what is trigonometric ratios  ?

To determine the angles of a right triangle, trigonometric ratios are ratios of the side lengths of the triangle. Sine (sin), cosine (cos), and tangent (tan) are the three fundamental trigonometric ratios, and their definitions are as follows:

Sine: The length of the angle's opposite side divided by the length of the hypotenuse is known as the sine of the angle.

Cosine: The length of the neighbouring side divided by the length of the hypotenuse is the angle's cosine value.

Angle's tangent is determined by dividing the length of the adjacent side by the length of the opposite side.

These ratios can be used to discover missing side lengths in right triangles and other situations with right triangles.

What does a maths percent mean?

In essence, percentages are fractions with a 100 as the denominator. We place the percent sign (%) next to the number to indicate that the number is a percentage.

What does the word "percentage" actually mean?

Rather than being stated as a fraction, a percent is a piece of an entire thing expressed as just a number between zero and 100. Nothing is zero percent; everything is 100 percent; half of something is 50 percent; and nothing is zero percent. You divide the part of the total by its entirety and multiply the result by 100 to get the percentage.

Blue Cab operates 12% of the taxis in a certain city, and Green Cab operates the other 88%. After a night-time hit-and-run accident involving a taxi, an eyewitness said the vehicle was blue. Suppose, though, that under night vision conditions, only 85% of individuals can correctly distinguish between a blue and a green vehicle. What is the probability that the taxi at fault was blue given an eyewitness said it was? Round your answer to 3 decimal places Write your answer as reduced fraction

Answers

The probability that the taxi at fault was blue given an eyewitness said it was is approximately 0.436.

To find the probability that the taxi at fault was blue given an eyewitness said it was, we can use Bayes' theorem. Bayes' theorem is expressed as: P(A|B) = (P(B|A) * P(A)) / P(B)

Where:
- P(A|B) is the probability of A given B (the probability the taxi is blue given the eyewitness said it was blue)
- P(B|A) is the probability of B given A (the probability the eyewitness said the taxi was blue given it was actually blue)
- P(A) is the probability of A (the probability the taxi is blue)
- P(B) is the probability of B (the probability the eyewitness said the taxi was blue)


First, let's define our events:
- A: The taxi is blue (Blue Cab), with a probability of 12% (0.12)
- B: The eyewitness said the taxi was blue

Now, we need to find P(B|A) and P(B).

1. P(B|A) = 0.85 (the probability the eyewitness correctly identifies the blue taxi)
2. P(B) can be found using the law of total probability: P(B) = P(B|A) * P(A) + P(B|A') * P(A')
  - A': The taxi is not blue (Green Cab), with a probability of 88% (0.88)
  - P(B|A') = 1 - 0.85 = 0.15 (the probability the eyewitness incorrectly identifies the green taxi as blue)

So, P(B) = 0.85 * 0.12 + 0.15 * 0.88 = 0.102 + 0.132 = 0.234

Now, we can apply Bayes' theorem:

P(A|B) = (P(B|A) * P(A)) / P(B)
P(A|B) = (0.85 * 0.12) / 0.234
P(A|B) ≈ 0.4359

Rounded to three decimal places, the probability that the taxi at fault was blue given an eyewitness said it was is approximately 0.436 or 436/1000 as a reduced fraction.

To determine the % Cr in the chromium-complex Legna synthesized, she massed out a 1.0240 g sample of the Cr complex. She dissolved the sample in a volumetric flask and made 100.0 mL of solution. From the standard curve of Absorbance versus concentration Legna obtained [Cr3+]=0.03933 M. Calculate the %Cr in the complex.

To determine the % Cr in the chromium-complex synthesized by Legna, we can use the following formula:% Cr = (mass of Cr/mass of sample) x 100We have the mass of the sample, which is 1.0240 g. We need to find the mass of Cr in the sample. To do this, we need to find the number of moles of Cr in the solution, and then use the molar mass of Cr to convert this to mass.

The concentration of Cr3+ in the solution is given as 0.03933 M. We know that the complex is made up of Cr and some other ligands, and the concentration of Cr3+ is not the same as the concentration of Cr in the complex. To find the concentration of Cr in the complex, we need to use the formula:[Cr] = [Cr3+] x (1/x), where x is the number of moles of Cr3+ in the complex.

Let's assume that there is one mole of Cr3+ in the complex, then x = 1. If there are n moles of Cr3+ in the complex, then x = n. We can find x by using the formula:x = (mass of sample/Mr of Cr3+) x [Cr3+]/volume of solutionWe know that the mass of the sample is 1.0240 g, and the volume of the solution is 100.0 mL = 0.1000 L. The molar mass of Cr3+ is 52.00 g/mol. Substituting these values into the formula, we get:x = (1.0240/52.00) x 0.03933/0.1000x = 0.000761 moles of Cr3+ in the complex

Now we can use the formula [Cr] = [Cr3+] x (1/x) to find the concentration of Cr in the complex:[Cr] = 0.03933/0.000761[Cr] = 51.69 M

Finally, we can use the formula:% Cr = (mass of Cr/mass of sample) x 100The molar mass of Cr is 52.00 g/mol. The mass of Cr in the complex is 51.69 x 52.00 = 2689.88 g/mol. Substituting this value and the mass of the sample (1.0240 g) into the formula, we get:% Cr = (2689.88/1.0240) x 100% Cr = 262944.53% Cr = 26.294%

Answers

The equation of this circle with a radius of 4/7 and is centered at (−2.5, −4.4) is (x + 2.5)² + (y + 4.4)² = 49/16.

It is given to us that a circle has a radius of 7/4 units and is centered at (−2.5, −4.4). We need to write an equation of this circle

Therefore, we can say that the standard form of a circle is:

(x - h)² + (y - k)² = r²

where, (h, k) is center and r is radius of the circle.

when we substitute h = -2.5, k = -4.4 and r = 7/4 in the above formula, we get:

= [x-(-2.5)]² + [y-(-4.4)]² = (7/4)²

= (x + 2.5)² + (y + 4.4)² = 49/16

Hence the equation of circle is (x + 2.5)² + (y + 4.4)² = 49/16.

MODELING REAL LIFE You deposit $5000 in an account earning 7. 5% simple interest per year. How long will it take for the balance of the account to be $6500?

Answers

We use the formula I = Prt where I is the interest earned, P is the principal, r is the interest rate per year, and t is the time in years. Substituting the values, we find that it will take 4 years for a $5000 balance to reach $6500 with a 7.5% simple interest rate.

To solve this problem, we can use the formula for simple interest:

I = Prt

Where I is the interest earned, P is the principal (initial amount), r is the interest rate per year (as a decimal), and t is the time in years.

In this case, we know that the principal is $5000, the interest rate is 7.5% or 0.075, and we want to find the time required for the balance to reach $6500.

Substituting these values into the formula, we get:

I = $6500 - $5000 = $1500

P = $5000

r = 0.075

t = ?

Solving for t, we get:

$1500 = $5000 * 0.075 * t

t = $1500 / ($5000 * 0.075)

t = 4

Therefore, it will take 4 years for the balance of the account to be $6500 with a 7.5% simple interest rate.

Answers

a) The rate of change of the drug's concentration at 50 minutes is 1.7 mg/min.

b) The rate of change of the drug's concentration at 85 minutes is 0.2 mg/min.

c) The drug's concentration is decreasing at 115 minutes.

a) The central difference approach can be used to calculate the rate of medication change after 50 minutes.

f'(x) = (f(x+h) - f(x-h))/2 × h    ....(1)

As per the question, we have h = 10 and x = 50

Substitute the values of h = 10 and x = 50 in (1),

f'(40) = (f(50+10) - f(50-10))/2 × 10

f'(40) = (89-55)/20

f'(40) = 1.7 mg/min

b) For the rate of change of concentration at 85 minutes:

Here, f(80) = 111 mg and f(90) = 113.

The concentration at 90 minutes is 113 mg.

Rate of change = (f(90) - f(80)) / h

= (113 - 111) /10

= 2 / 10

= 0.2 mg/min

c) Since the concentration at 120 minutes (68 mg) is lower than the concentration at 110 minutes (103 mg), the drug's concentration is decreasing.

Therefore, the drug's concentration is decreasing at 115 minutes.

Answers

As per the given average, the solution of the breakeven w/ hidden costs is 62% higher.

Let's assume that the costs associated with running a 315-ticket run are $7,592. This means that on average, each ticket needs to sell for $24.10 (($7,592/315) = $24.10) to break even.

Similarly, if we consider the other two runs, we can calculate the average number of tickets needed to break even per show as follows:

For the 323-ticket run, the average number of tickets needed to break even per show is 65. (($7,784/323) = $24.10)

For the 331-ticket run, the average number of tickets needed to break even per show is 56. (($7,977/331) = $24.10)

Furthermore, we can calculate the break-even occupancy percentage for each run, which is the percentage of tickets that need to be sold to break even. The break-even occupancy for each run is as follows:

For the 331-ticket run,

=> 56/331 = 0.17 or 17%,

=> 1-0.17 = 0.83 or 83%,

=> 0.83/0.17 = 4.88,

=> 4.88 x 100% = 488%,

=> 488% x 0.62 = 303%,

=> 303%/4.88 = 62%

an apple falls from a tree 100 km to the ground. if the acceleration due to gravity is 9,8 m/s² and the mass of the apple is 0,2 gram. what is the potential energy of the apple?

Answers

Answer: 196 Joules (J)

Step-by-step explanation:

To calculate the potential energy of the apple, we can use the formula:

Potential Energy = Mass x Gravity x Height

First, let's convert the height from kilometers to meters:

100 km = 100,000 meters

Now, let's convert the mass of the apple from grams to kilograms:

0.2 gram = 0.0002 kilograms

Using these values, we can calculate the potential energy:

Potential Energy = 0.0002 kg x 9.8 m/s^2 x 100,000 m

Potential Energy = 196 Joules (J)

Therefore, the potential energy of the apple is 196 Joules (J).

Answers

The amount of plastic wrap required to cover the entire cone will be 16.575 square inches.

To calculate how much plastic wrap is required to completely cover an ice cream cone with a slant height of 4.25 inches and a diameter of 2 inches, we must use the surface area of the cone.

Here, the ice cream cone can be visualized as a cone-shaped object with an added circular base.

We must use the following formula to calculate the surface area:

Surface area = πr2 + πrl

Where r is the radius and l is the slant height of the cone.

As we know the diameter of the ice cream cone is 2 inches, and its radius can be calculated by dividing it by

2.r = d/2 = 2/2 = 1 inch.

Substitute the values of r and l in the formula, and then calculate the surface area of the cone.

π = 3.14r = 1 inchl = 4.25 inches

Surface area = πr2 + πrl

                     = 3.14 × 1² + 3.14 × 1 × 4.25

There are a total of 7 ways to seat eight people around a table if Alice and Bob won't sit next to each other. This is because the seating arrangement must be a permutation of the seven people not including Alice and Bob.

We can calculate this by taking the factorial of the number of people not including Alice and Bob, which is seven. Since a factorial is the product of an integer and all the integers below it, we can calculate the factorial of seven by multiplying all the integers from one to seven.

Also given that the length of BC = 6 units

Here we can see that:

As both triangles are similar, their corresponding sides are in proportion.

This means that:

Thus, the solution to the initial value problem is:[tex]y(t) = - y'(t) + \frac{5}{2} (-\frac{1}{5} (y''(0) - 20)) e^{2t} + 3 e^{2t}[/tex]

In this case, the student is asking about an initial value problem with a given differential equation. The differential equation is:[tex]y(t) = y'(t) - 2y(0) + 5[/tex]The initial condition is:y'(0) = 4To solve this initial value problem, we can use the method of integrating factors. First, we need to find the integrating factor. The integrating factor is given by:[tex]e^{∫ -2 dt} = e^{-2t}[/tex]

Now we can multiply both sides of the differential equation by the integrating factor to get:

[tex]e^{-2t} y(t) = e^{-2t} y'(t) + 5e^{-2t} y(0)[/tex]

We can now integrate both sides of this equation with respect to t to get:[tex]e^{-2t} y(t) = - e^{-2t} y'(t) + \frac{5}{-2} e^{-2t} y(0) + C[/tex]where C is the constant of integration.

To find C, we can use the initial condition:y'(0) = 4Substituting this into the equation above gives:C = 3Now we can solve for y(t) by multiplying both sides of the equation by[tex] e^{2t}:y(t) = - y'(t) + \frac{5}{2} y(0) e^{2t} + 3 e^{2t}[/tex]

Finally, we can use the initial condition y'(0) = 4 to solve for the value of[tex] y(0):y'(0) = - y''(0) + 5y(0) + 6y'(0) = - y''(0) + 5y(0) + 24[/tex]

Since y'(0) = 4, we have:[tex]4 = - y''(0) + 5y(0) + 24[/tex]Solving for y(0), we get:[tex]y(0) = -\frac{1}{5} (y''(0) - 20)[/tex]

Answers

The height of the cone is 13.38 units

What is volume of a cone?

A cone is a three-dimensional shape in geometry that narrows smoothly from a flat base (usually circular base) to a point(which forms an axis to the centre of base) called the apex or vertex.

The volume of a cone = 1/3 πr²h

volume = 2016 units³

r = d/2 = 24/2 = 12 units

2016 = 1/3 × 3.14 × 12² h

6048 = 452.16h

h = 6048/452.16

h = 13.38units

therefore the height of the cone is 13.38 units

a) Take a 20-question examination Number of questions answered correctly Discrete (0, 1, 2, 3, ..., 20)

b. Observe cars arriving at a tollbooth Number of cars arriving at tollbooth for 1 hour Discrete (0, 1, 2, 3, ...)

c. Audit 50 tax returns Number of returns containing errors Discrete (0, 1, 2, 3, ...)

d. Observe an employee’s work Number of nonproductive hours in an eight-hour workday Continuous

e.Weigh a shipment of goods Number of pounds Continuous Random variables are numerical values that are a result of a random experiment. Random variables are generally classified into two categories

Solution:

discrete random variables and continuous random variables

.Discrete random variables

 When a random variable can assume only a countable number of values, it is called a discrete random variable.

Examples: the number of cars passing by a particular point of a highway in a day or the number of customers served by a shop in a day.

Continuous random variables: 

When a random variable can assume any value within a given range or interval, it is called a continuous random variable.

Examples: temperature, the weight of a person, or the height of a person.Tax returns: The random variable is discrete, as it can only take certain values (0, 1, 2, 3, and so on) since the number of tax returns containing errors is an integer.The shipment of goods: The random variable is continuous because it can assume any value between the minimum and maximum weight of the shipment, and the weight of the shipment can be any value.

In a pond, the ratio of newts to toads was 3:4
9 more toads then entered the pond, and the ratio of newts to toads became 3:5

Work out how many newts are in the pond

Answers

The initial number of newts and toads in the pond were in the ratio 3:4, making the total number of organisms in the pond 7x. Solving for x, we get the initial number of toads and newts in the pond as 108 and 81.

Let's assume that the initial number of newts and toads in the pond were 3x and 4x, respectively. Therefore, the total number of organisms in the pond would be 7x.

When 9 more toads entered the pond, the number of toads became 4x + 9, and the ratio of newts to toads changed to 3:5. This means that the number of newts and toads in the pond increased by a factor of 3/2 and 5/4, respectively. We can set up the following equation to solve for x:

3/2n = 4x + 9

5/4n = 4x + 9

Simplifying these equations, we get:

6x + 18 = 5x + 45

x = 27

So, the initial number of toads in the pond was 4x = 108, and the initial number of newts was 3x = 81.

How many possible outcomes are in the sample space?

Answers

The total number of possible outcomes in the sample space for three coin flips is 8.

When a coin is flipped three times, the sample space consists of all possible outcomes that can occur in the experiment. In this case, each coin flip can result in one of two possible outcomes: heads or tails. Therefore, the total number of possible outcomes in the sample space is obtained by multiplying the number of possible outcomes for each individual flip, since each flip is independent of the others.

Thus, the total number of possible outcomes in the sample space for three coin flips is 2 x 2 x 2 = 8. These outcomes include all possible combinations of heads and tails, such as HHH, HHT, HTH, THH, HTT, THT, TTH, and TTT. Each outcome has an equal probability of occurring, assuming the coin is fair and unbiased.
