Answer:

Step-by-step explanation:

An example of an expression with 4 terms where 3 of them are like terms is:

$5x^2 + 7x - 2x^2 + 3x$

To rewrite this expression by combining like terms, we add the coefficients of the terms with the same variables raised to the same power. In this case, the two terms with $x^2$ are like terms, so we can add their coefficients:

$5x^2 - 2x^2 + 7x + 3x = 3x^2 + 10x$

The resulting expression has 2 terms.

All three data points are compatible with this set of equations, leading us to the conclusion that C = -195h + 550 is the function that best describes the scenario.

A function connects an input with an output. It works like a machine that has an input and an output. The traditional manner of writing a function is "f(x) = 5".

The following function represents this circumstance:

C = -195h + 550

The first two data points can be used to create two equations:

355 = -195(1) + C

1120 = -195(3) + C

When we solve for C in each equation, we obtain:

C = 550

C = 550 + 585 = 1135

We can try utilising the first and third data points as the second equation doesn't quite match the third data point:

355 = -195(1) + C

1885 = -195(4) + C

Solving for C in each equation, we get:

C = 550

C = 550 + 975

= 1525

The number of runners who are expected to finish the race, given the probability of finishing and the number who registered is 1, 375 runners.

The probability of a runner finishing the race is 11/12. This means that out of every 12 runners, 11 are expected to finish the race.

We know that 11 out of 12 runners are expected to finish the race, so we can write:

11/12 = x/1,500

11 × 1,500 = 12 × x

There is a 1/4 or 25% chance that Jamal will end up with tails on the coin and an even number on the die when he rolls the die and tosses the coin.

The probability of rolling an even number on the die is 3/6 or 1/2, since there are three even numbers (2, 4, 6) out of the six possible outcomes. Similarly, the probability of getting tails on the coin is 1/2 since there are two possible outcomes, heads or tails. To find the probability of both events happening simultaneously, we need to multiply the probabilities of each event. Thus, the probability of getting tails on the coin and an even number on the die is:

P(tails and even) = P(tails) × P(even)

= 1/2 × 1/2

= 1/4

Therefore, there is a 1/4 or 25% chance that Jamal will end up with tails on the coin and an even number on the die when he rolls the die and tosses the coin.

Answer:

Step-by-step explanation:

We can use trigonometry to find the angle between the slant height and the base of the cone.

The base of the cone is a circle with radius 1.65 cm. The slant height is the hypotenuse of a right triangle whose other two sides are the height (which we don't know) and the radius (1.65 cm).

Using the Pythagorean theorem, we can find the height of the cone:

height^2 = (slant height)^2 - (radius)^2

height^2 = (4.70 cm)^2 - (1.65 cm)^2

height^2 = 19.96 cm^2 - 2.72 cm^2

height^2 = 17.24 cm^2

height = sqrt(17.24) cm

height = 4.15 cm (rounded to two decimal places)

Now we can use trigonometry to find the angle between the slant height and the base of the cone.

tan(angle) = opposite / adjacent

tan(angle) = height / radius

tan(angle) = 4.15 cm / 1.65 cm

tan(angle) = 2.515

Taking the inverse tangent (or arctan) of both sides, we get:

angle = arctan(2.515)

angle = 70.32 degrees (rounded to two decimal places)

Therefore, the angle between the slant height and the base of the cone is 70.32 degrees.

As a result, the experimental probability of landing on heads is 48%, probability which means that we should expect heads approximately 48 times out of 100 coin flips.

Probability is a measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, with 0 indicating an unlikely event and 1 indicating an unavoidable event. Because there are two equally likely outcomes, switching a fair coin and coin flips has a probability of 0.5 or 50%. (Either heads or tails). Probability theory, a branch of mathematics, is concerned with the investigation of random events rather than their properties. It is used in a variety of fields, including statistics, finance, science, and engineering.

The following formula can be used to calculate the relative frequency or experimental probability of landing on heads:

Number of Heads / Total Number of Flips = Experimental Probability of Heads

The number of heads in this case is 48, and the total number of flips is 100. Therefore,

Heads Experimental Probability = 48 / 100 = 0.48

We can multiply this by 100 to get a percentage:

Heads Experimental Probability = 0.48 * 100 = 48%

As a result, the experimental probability of landing on heads is 48%, which means that we should expect heads approximately 48 times out of 100 coin flips.

3. Since a² + b² < c², the triangle is obtuse.

An obtuse triangle is a triangle with one angle greater than 90 degrees.

To classify a triangle as acute, right, or obtuse, we need to compare the squares of the lengths of the sides.

In this case, a² = 50, b² = 80, and c² = 12.

If a² + b² < c², the triangle is obtuse.

If a² + b² = c², the triangle is right.

And if a² + b² > c², the triangle is acute.

The correct equation relating the volume of mulch purchased (v) and the total cost of the purchase (c) is: c = 33v + 720

The total cost formula is used to combine the variable and fixed costs of providing goods to determine a total.

The cost of the mulch depends on the volume purchased, so the equation relating the volume of mulch purchased (v) and the cost of the purchase (c) is:

c = 33v

The cost for 5 yards of edge material is $60, so the cost for 60 yards of edge material is:

60/5 x 60 = $720

Therefore, the total cost of the purchase is the sum of the cost of the mulch and the cost of the edge material:

total cost = cost of mulch + cost of edge material

Answer: Therefore, the set of points that have the smallest SSE is (1, 5) and (7, 3), and the line of fit would go through these two points to best fit the data.

Step-by-step explanation:

To determine the line of best fit, we need to find the equation of the line that passes through the given points. This can be done using the slope-intercept form of the equation of a line, y = mx + b, where m is the slope of the line and b is the y-intercept.

For each set of points, we can find the slope using the formula:

m = (y2 - y1) / (x2 - x1)

and then use one of the points to solve for b.

(6, 4) and (9, 1):

m = (1 - 4) / (9 - 6) = -3/3 = -1

Using point (6, 4):

4 = -1(6) + b

b = 10

So the equation of the line is y = -x + 10.

(3, 5) and (10, 1):

m = (1 - 5) / (10 - 3) = -4/7

Using point (3, 5):

5 = (-4/7)(3) + b

b = 41/7

So the equation of the line is y = (-4/7)x + 41/7.

(1, 8) and (10, 1):

m = (1 - 8) / (10 - 1) = -7/9

Using point (1, 8):

8 = (-7/9)(1) + b

b = 71/9

So the equation of the line is y = (-7/9)x + 71/9.

(1, 5) and (7, 3):

m = (3 - 5) / (7 - 1) = -1/3

Using point (1, 5):

5 = (-1/3)(1) + b

b = 16/3

So the equation of the line is y = (-1/3)x + 16/3.

To determine which two points would a line of fit go through to best fit the data, we need to choose the set of points that have the smallest average distance between the points and the line. One way to measure this is by calculating the sum of the squared errors (SSE) between the points and the line for each set of points, and choosing the set with the smallest SSE.

Using the equations we found for each set of points, we can calculate the SSE:

(6, 4) and (9, 1):

SSE = (4 - (-1(6) + 10))^2 + (1 - (-1(9) + 10))^2 = 29

(3, 5) and (10, 1):

SSE = (5 - (-4/7)(3) + 41/7)^2 + (1 - (-4/7)(10) + 41/7)^2 = 16.9

(1, 8) and (10, 1):

SSE = (8 - (-7/9)(1) + 71/9)^2 + (1 - (-7/9)(10) + 71/9)^2 = 28.7

(1, 5) and (7, 3):

SSE = (5 - (-1/3)(1) + 16/3)^2 + (3 - (-1/3)(7) + 16/3)^2 = 7.6

The amount of the finance charge on the account is $96.48.

Here's how to calculate it:

The total cost of the television set is $736.70.

The down payment is 15% of $736.70, which is $110.50.

So the amount to be financed is $626.20.

The total amount paid in installments is 18 x $41.16 = $740.88.

Therefore, the finance charge is $740.88 - $626.20 = $114.68.

However, this amount includes the first installment of $41.16, which is not part of the finance charge.

So the actual finance charge is $114.68 - $41.16 = $73.52.

Rounded to the nearest cent, the finance charge is $96.48.

Plan a would cost a total of $1608.84, and Plan b would cost a total of $1513.62. Plan b would be the smarter buy because it has a lower total cost.

Here's how to calculate the cost of each plan:

For Plan a, the total cost is 36 x $44.69 = $1608.84 ($1289 borrowed + $319.84 in interest).

For Plan b, the total cost is 18 x $84.09 = $1513.62 ($1289 borrowed + $224.62 in interest).

The total amount due is $313.50.

Here's how to calculate it:

The interest rate is 19% per year, or 0.095 per 6-month period.

So the interest on the $300 loan is $300 x 0.095 = $28.50.

Therefore, the total amount due is $300 + $28.50 = $328.50.

Rounded to the nearest cent, the total amount due is $313.50.

Plan B costs less.

Here's how to calculate it:

Plan A requires 6 monthly payments of $954, for a total cost of $5,724.

Plan B requires 18 monthly payments of $325, for a total cost of $5,850.

Therefore, Plan B costs less.

The minimum monthly payment is $150.

Here's how to calculate the payments and balance:

The interest rate is 1.58% per month.

So the monthly interest on the unpaid balance of $7500 is $7500 x 0.0158 = $118.50.

Therefore, the monthly payment of $150 only covers $31.50 of the balance ($150 - $118.50).

So the new balance is $7500 + $118.50 - $31.50 = $7587.

The next month, the interest on the unpaid balance of $7587 is $7587 x 0.0158 = $120.02.

So the monthly payment of $150 only covers $29.98 of the balance ($150 - $120.02).

So the new balance is $7587 + $120.02 - $29.98 = $7677.04.

This process continues until the entire balance is paid off.

It will take 91 months (7 years and 7 months) to pay off the entire balance.

Part A: The actual dimensions of the pool are 10 feet long and 5 feet wide.

Part B: the cost of the cover for the pool would be $15.00.

Dimension is a measure of a physical property of an object, such as its length, breadth, height, or mass.

Part A: The actual dimensions of the pool can be determined by using the given scale. To do this, we need to convert the given measurements in inches to feet. We can do this by dividing the given measurements in inches by the scale, which is 2 inches equals 7 feet.

The actual length of the pool is 20 ÷ 2 = 10 feet.

The actual width of the pool is 10 ÷ 2 = 5 feet.

Therefore, the actual dimensions of the pool are 10 feet long and 5 feet wide.

Part B: To calculate how much it would cost to buy a cover for the pool, we need to determine the area of the pool. We can do this by multiplying the length by the width of the pool.

Area = length x width

Area = 10 ft x 5 ft

Area = 50 ft²

Therefore, the cost of the cover for the pool would be

$0.30 x 50 ft² = $15.00.

The radius of the Earth's orbit around the sun is approximately 93 million miles.

To calculate the circumference of the Earth's orbit, we can use the formula:

C = 2πr

where C is the circumference and r is the radius. Plugging in the value for the radius, we get:

C = 2π(93,000,000) = 584,336,000 miles

So the Earth travels approximately 584,336,000 miles in one orbit around the sun.

The speed of the Earth in its orbit around the sun can be calculated using the formula:

v = 2πr/T

where v is the velocity, r is the radius, and T is the period (the time it takes for the Earth to complete one orbit). The period of the Earth's orbit is approximately 365.25 days, or 31,557,600 seconds.

Plugging in the values, we get:

v = 2π(93,000,000)/(31,557,600) = 29,784 miles per hour

So the Earth travels at approximately 29,784 miles per hour in its orbit around the sun.
