5 cards are drawn randomly from a regular deck of cards. how many ways can you draw 5 cards and get 4 hearts and 1 spade?

Answers

Answer 1

Answer:

There are 13 hearts in a deck of cards, so the probability of drawing a heart on the first draw is 13/52. After the first heart is drawn, there are 12 hearts left in the deck out of a total of 51 cards, so the probability of drawing another heart is 12/51. This process continues until we have drawn 4 hearts and 1 spade. Therefore, the total number of ways to draw 5 cards with 4 hearts and 1 spade is:

(13/52) x (12/51) x (11/50) x (10/49) x (13/48) x 5!

The factor of 5! accounts for the fact that the 5 cards can be drawn in any order. Simplifying the expression above, we get:

(13/52) x (12/51) x (11/50) x (10/49) x (13/48) x 120 = 0.000495 or approximately 1 in 2,020 ways.

Therefore, there are approximately 2020 ways to draw 5 cards from a regular deck of cards and get 4 hearts and 1 spade.

Answer 2

There are 54,145,200 ways to draw 5 cards and get 4 hearts and 1 spade from a regular deck of cards.

There are 13 hearts in a deck of cards, so the probability of drawing a heart on the first draw is 13/52 or 1/4. The probability of drawing another heart on the second draw, given that one heart has already been drawn, is 12/51. The same goes for the third and fourth draws. The probability of drawing a spade on the fifth draw is 13/50.

To calculate the number of ways to draw 4 hearts and 1 spade, we need to multiply the number of ways to choose 4 hearts from 13 (13 choose 4 or 715) by the number of ways to choose 1 spade from 13 (13 choose 1 or 13) and then multiply that by the number of ways to arrange those 5 cards (5!). So, the total number of ways is:

715 * 13 * 5! = 54,145,200

Therefore, there are 54,145,200 ways to draw 5 cards and get 4 hearts and 1 spade from a regular deck of cards.

a cheetah travels at a rate of 90 feet per second. the distance d traveled by the cheetah is a function of seconds traveled t. write a rule for the function.

Answers

The function rule for this question is d = 90t.

The rate of the cheetah is given as 90 feet per second. The distance travelled by the cheetah is a function of seconds travelled. Let the distance be denoted as d and the time be denoted as t. The function is therefore a linear function of the form y = mx + b.

The equation can be expressed as d = 90t + b. The constant b is the initial distance travelled at time zero since the rate is constant. Therefore, b is zero when the time is zero. The final equation is given as follows: d = 90t, where d is the distance travelled, t is the time and 90 is the rate or speed of the cheetah.

As a result, the following is the system of equations' solution as  12x - 2y = 20 in the calculation, x = 7/4 and y = 1/2.

what is equation ?

A mathematical assertion proving the equality of two expressions is known as an equation. It has two sides—a left side and a right side—that are divided by the equal symbol (=). Variables, constants, and mathematical processes may be used in the expressions on either side of the equal sign. For instance, the expression 2x + 3 on the left is equivalent to the expression 7 on the right, as shown by the equation 2x + 3 = 7.

given

We can use the technique of elimination to solve this system of equations by adding or removing one of the variables from the equations. In this instance, by combining the two equations, we can remove y:

12x - 2y = 20

16x + 2y = 29

28x = 49

We can now find the value of x by multiplying both parts by 28:

28x/28 = 49/28

x = 7/4

We can solve for y by substituting this value of x into either of the initial equations. Let's employ the initial equation:

12x - 2y = 20

12(7/4) - 2y = 20

21 - 2y = 20

-2y = -1

y = 1/2

As a result, the following is the system of equations' solution as  12x - 2y = 20 in the calculation, x = 7/4 and y = 1/2.

WHAT IS TRIGONOMETRY ?

Trigonometry is a branch of mathematics that deals with the study of the relationships between the sides and angles of triangles. It is used to solve problems involving distances, heights, angles, and other geometric measurements. Trigonometric functions such as sine, cosine, and tangent are used to relate the angles of a triangle to its sides. Trigonometry has many practical applications in fields such as engineering, physics, and architecture, and is essential for understanding and solving problems involving waves, oscillations, and periodic phenomena. It is also used in navigation, surveying, and astronomy, among other areas.

To solve this problem, we need to use the concept of right triangle trigonometry.

Let's assume that point C is directly opposite the midpoint of AB, and that the distance from point C to the midpoint of AB is x. Then we can draw a right triangle with legs of length x and 25 (half of 50) and a hypotenuse of length d (the distance from point C to each landing point).

Using the Pythagorean theorem, we can write:

d^2 = x^2 + 25^2

We also know that the angles opposite the legs of the right triangle are complementary, so we can use the tangent function to write:

tan(theta) = x/25

where theta is the angle between the hypotenuse and the side of length 25.

We can rearrange this equation to solve for x:

x = 25 tan(theta)

Now we can substitute this expression for x into the equation for d^2:

d^2 = (25 tan(theta))^2 + 25^2

Simplifying this equation, we get:

d^2 = 25^2 (tan^2(theta) + 1)

Finally, we can use the fact that tan(theta) is equal to the height of the opposite bank divided by the distance from point C to the midpoint of AB. Let's call this distance y. Then we have:

tan(theta) = y/x

Substituting this expression for tan(theta) into the equation for d^2, we get:

d^2 = 25^2 (y^2/x^2 + 1)

So the distance from each landing point to the boat pulled ashore at point C is given by:

d = sqrt(25^2 (y^2/x^2 + 1))

where x and y are the distances from point C to the midpoint of AB and the opposite bank, respectively.

tycho plans his running training. each week he wants to go for a run on the same weekdays. he never wants to go for a run on two consecutive days. but he wants to go for a run two days a week. how many different weekly plans meet those conditions?

Answers

There are 4 different weekly plans that meet the condition

If Tycho wants to go for a run on the same weekdays every week, there are 7 choices for the first day of the week, 6 choices for the second day of the week, and 5 choices for the third day of the week (since he can't run on two consecutive days).

However, we have to be careful not to overcount the number of plans that meet the conditions. For example, if Tycho chooses Monday and Tuesday as his running days, that's the same as choosing Tuesday and Monday.

To avoid overcounting, let's first count the total number of possible plans, regardless of whether they meet the conditions or not. We can choose any two days of the week for Tycho to run, which can be done in 7 choose 2 ways (or C(7,2) ways), since order doesn't matter.

C(7,2) = 7!/(2!(7-2)!) = 21

So there are 21 possible plans, regardless of whether they meet the conditions or not.

Now let's count the number of plans that meet the conditions. Since Tycho wants to run on two days a week and not on consecutive days, there are only two possible patterns: (1) run on Monday and Thursday, or (2) run on Tuesday and Friday.

Each pattern can be done in 2 ways: either run on Monday and Thursday, or run on Thursday and Monday. Similarly, either run on Tuesday and Friday, or run on Friday and Tuesday.

So there are 4 plans that meet the conditions: (Monday, Thursday), (Thursday, Monday), (Tuesday, Friday), and (Friday, Tuesday).

Therefore, there are 4 different weekly plans that meet the condition

Vincent bought a lot with an area of 105. 7 square meters at 12,500. 00 pesos per square meter. He paid -0. 45 of the amount in cash and the rest 24 equal monthly installments. How many much is his monthly installment?

Answers

The amount to be paid as monthly installment for 24 equal monthly installments is given by 30,278.65 pesos.

Area bought by Vincent =  105. 7 square meters

Cost per square meters =  12,500. 00 pesos per square meter.

The total cost of the lot is the product of the area and the price per square meter,

Cost

= 105.7 sq m ×12,500.00 pesos/sq m

= 1,321,250.00 pesos

Amount paid by Vincent in cash is equals to

= 0.45 × 1,321,250.00 pesos

= 594,562.50 pesos

The remaining balance to be paid in installments is equals to,

= 1,321,250.00 pesos - 594,562.50 pesos

= 726,687.50 pesos

This balance will be paid in 24 equal monthly installments, so the monthly installment amount is equals to,

= 726,687.50 pesos / 24 months

= 30,278.65 pesos per month (rounded to the nearest cent)

Therefore, amount paid by Vincent as monthly installment is equal to 30,278.65 pesos.

How much more expensive is it, per pound, to buy chicken thighs at Store B than at Store A?

Answers

Answer:

To find out how much more expensive it is, per pound, to buy chicken thighs at Store B than at Store A, we need to compare the cost per pound at each store.

At SuperGrocery B, we know that 3 pounds of chicken thighs cost $34.80, so the cost per pound is:

$34.80 / 3 pounds = $11.60 per pound

At SuperGrocery A, we can use the information in the table to find the cost per pound for each amount of chicken thighs:

For 1.5 pounds of chicken thighs:

$13.52 / 1.5 pounds = $9.01 per pound

For 3 pounds of chicken thighs:

$27.03 / 3 pounds = $9.01 per pound

For 3.5 pounds of chicken thighs:

$31.54 / 3.5 pounds = $9.01 per pound

For 4.5 pounds of chicken thighs:

$40.55 / 4.5 pounds = $9.01 per pound

So the cost per pound of chicken thighs at SuperGrocery A is $9.01 per pound, which is less expensive than the cost per pound at SuperGrocery B, which is $11.60 per pound.

To find the difference between the two prices, we can subtract the cost per pound at SuperGrocery A from the cost per pound at SuperGrocery B:

$11.60 per pound - $9.01 per pound = $2.59 per pound

Therefore, it is $2.59 more expensive, per pound, to buy chicken thighs at SuperGrocery B than at SuperGrocery A.

(x - 3)(x + 4) What is the horizontal distance between the two x-intercepts?

Answers

Answer:

The horizontal distance between the two x-intercepts is 7 units.

Step-by-step explanation:

What are the x-intercepts?

The x-intercepts are the points at which the graph of a function or equation crosses the x-axis.  At these points, the value of y is zero.

Therefore, to find the x-intercepts of the given expression, set the expression equal to zero and solve for x:

(x - 3)(x + 4) = 0

This equation is true if and only if either x - 3 = 0 or x + 4 = 0, which means the x-intercepts are at x = 3 and x = -4.

The horizontal distance between these two points is the absolute value of the difference between the x-coordinates of the x-intercepts:

|3 - (-4)| = |3 + 4| = 7

Therefore, the horizontal distance between the two x-intercepts is 7 units.

one business has a large amount of debt on which it pays an annual yield of 8%. a competitor has no debt, and any excess money goes into the bank and earns a yield of 2.3%. each of these businesses bids on a contract which pays $ 40,000 in one year and nine months. indicate which company gives this contract a higher present value, and calculate the difference between these present values, rounding to the nearest dollar. [hint: for both businesses the yield is treated as positive.]

Answers

This gives us a present value for the company with debt of $35,564 and a present value for the competitor without debt of $36,944. The difference in present values is $1,380, rounded to the nearest dollar. Therefore, the company with debt gives the contract a higher present value of $1,380.

The company with debt will have the higher present value for this contract. This is because, despite having a higher yield, the competitor without debt is only earning 2.3% on their excess money, while the company with debt is earning 8%.


To calculate the difference in present values, we need to first calculate the present value of each company's contract. To do this, we will use the present value formula, which is:


[tex]PV = C / (1 + r)n[/tex]

Where C is the contract amount, r is the rate of return, and n is the number of years. For the company with debt, we can substitute $40,000 for C, 8% for r, and 1.75 for n. For the competitor without debt, we can substitute $40,000 for C, 2.3% for r, and 1.75 for n.

a centrifuge in a medical laboratory rotates at an angular speed of 3450 rev/min in the positive direction. when switched off, it rotates through 45.8 revolutions before coming to rest. Find the constant angular acceleration of the centrifuge.

Answers

The constant angular acceleration of the centrifuge is approximately [tex]-331283[/tex] rad/min² in the negative direction.

To find the constant angular acceleration of the centrifuge, we can use the following kinematic equation:

ω² = ω₀² + 2αθ

Here, ω is the final angular velocity (0 rad/min, since it comes to rest), ω₀ is the initial angular velocity (3450 rev/min), α is the constant angular acceleration we want to find, and θ is the angular displacement (45.8 revolutions).

First, we need to convert the given angular values to radians. We know that 1 revolution equals 2π radians.

Initial angular velocity, ω₀ = 3450 rev/min × 2π rad/rev = 6900π rad/min

Angular displacement, θ = 45.8 rev × 2π rad/rev = 91.6π rad

Now, substitute the values into the kinematic equation:

[tex]0 = (6900π)² + 2α(91.6π)[/tex]

[tex]α = - (6900π)² / (2 × 91.6π)[/tex]

[tex]α ≈ -331283 rad/min²[/tex]

Since the area is less than [tex]$60\pi$[/tex]square inches, this equation can be rewritten as[tex]$60\pi > \pi r^2$[/tex]. We can then divide both sides by [tex]$\pi$[/tex] to get [tex]$60 > r^2$[/tex]. Taking the square root of both sides gives us [tex]$r < \sqrt{60}$[/tex]. This result can then be rounded down to the nearest integer, which is 7. Therefore, the greatest possible integer value of the radius of the circle is 7 inches.

one of four different prizes was randomly put into each box of a cereal. if a family decided to buy this cereal until it obtained at least one of each of the four different prizes, what is the expected number of boxes of cereal that must be purchased?

Answers

The expected number of boxes of cereal that must be purchased to obtain at least one of each of the four different prizes is 1.

Let X be the number of boxes of cereal that need to be purchased to obtain at least one of each of the four different prizes. We want to find E(X), the expected value of X.

To do this, we can use the concept of the geometric distribution. The probability of obtaining a new prize in a box of cereal is given by:

p = 4/4 = 1 (since there are four different prizes)

The probability of not obtaining a new prize in a box of cereal is

q = 1 - p = 0

Therefore, X follows a geometric distribution with parameter p = 1. The expected value of a geometric distribution with parameter p is

E(X) = 1/p

So in this case, we have

E(X) = 1/1 = 1

This means that on average, the family will need to purchase one box of cereal to obtain at least one of each of the four different prizes.

find two divergent series summation from n equals 1 to infinity of the quantity a sub n and summation from n equals 1 to infinity of the quantity b sub n such that summation from n equals 1 to infinity of the quantity a sub n times b sub n end quantity converges.

Answers

To find two divergent series, summation from n equals 1 to infinity of a_n and summation from n equals 1 to infinity of b_n, such that their product converges, we can consider the following series:

1. Summation from n equals 1 to infinity of a_n = ∑(1/n)
2. Summation from n equals 1 to infinity of b_n = ∑n

Solution:

1. The first series, ∑(1/n), is known as the harmonic series. It is a famous example of a divergent series, meaning that its sum approaches infinity as n approaches infinity.

2. The second series, ∑n, is an arithmetic series where the terms increase linearly. This series is also divergent, as the sum increases without bound as n approaches infinity.

Now, we need to verify that the product of these series converges:

3. Summation from n equals 1 to infinity of (a_n * b_n) = ∑((1/n) * n)

4. Simplifying the expression, we get ∑(1), which is a constant series with all terms equal to 1.

5. The sum of the constant series converges, as it approaches a finite value when n approaches infinity.

In conclusion, the two divergent series summation from n equals 1 to infinity of a_n = ∑(1/n) and

summation from n equals 1 to infinity of b_n = ∑n, have a product that converges, as their product ∑((1/n) * n) simplifies to a constant series ∑(1), which has a finite sum.

the mean cost of 4 computer keyboards is $12 each. if the cost of a fifth computer keyboard is $16, what is the mean cost for all 5 computer keyboards?

Answers

The mean cost for all 5 computer keyboards is $12.80.

The mean cost, also known as the average cost, is a measure of central tendency that represents the typical or average cost of a set of values

To find the mean cost of all 5 computer keyboards, we need to calculate the total cost of all 5 keyboards and then divide by the total number of keyboards.

The total cost of the first 4 keyboards is

= 4 keyboards x $12 each

Multiply the numbers

= $48

The total cost of all 5 keyboards is

= $48 + $16

Add the numbers

= $64

The mean cost of all 5 keyboards is

= $64 / 5 keyboards

a random sample of 150 teachers in an inner-city school district found that 72% of them had volunteered time to a local charitable cause within the past 12 months. what is the standard error of the sample proportion?

Answers

The standard error for the sample proportion of 150 teachers in an inner-city school district is found to be 0.037.

The formula for the calculation of the standard error of a sample proportion is below,

SE = √((p × (1 - p)) / n)

Here,

SE is the standard error of the sample proportion

p is the sample proportion (in decimal form)

n is the sample size

In the mentioned case, the sample proportion is 0.72 (since 72% of 150 is 108), and the sample size is 150. Substituting these values into the formula, we will be getting,

SE = √((0.72 × (1 - 0.72)) / 150)

SE = √((0.2052) / 150)

SE = √(0.001367)

SE = 0.037

Therefore, the standard error of the sample proportion is 0.037.

The assessed value of the Weber family’s house is $186,000. The annual property tax is 2. 15% of assessed value. What is the property tax on the Webers home?

Answers

the property tax on the Weber family's home is $3,999. To find the property tax on the Weber family's home, we can use the formula:

Property tax = assessed value x tax rate

First, we need to convert the tax rate from a percentage to a decimal. We can do this by dividing the tax rate by 100:

2.15% ÷ 100 = 0.0215

Now we can plug in the values we know into the formula:

Property tax = $186,000 x 0.0215

Property tax = $3,999

So the property tax on the Weber family's home is $3,999.

Property taxes are a common way for local governments to generate revenue to fund public services like schools, roads, and emergency services. The tax rate is usually based on the assessed value of the property, which is determined by a local assessor's office. It's important for homeowners to be aware of the property tax rates in their area so they can budget for this expense. Some homeowners may be eligible for property tax exemptions or reductions, so it's also worth checking with the local assessor's office to see if there are any options available.
