Answer 1

Answer:

-0.6000

Step-by-step explanation:

sin² A + cos² A = 1

sin² A = 1 - Cos² A

= 1 - (4/5)²

= 1 - 0.64

= 0.36

sin A = sqrt 0.36 = 0.6

in quadrant IV sin is negative

sin A = -0.6000

The number of siblings each student at a softball game has is recorded. The graph below shows the probability distribution of having any number of siblings, X, for a randomly selected student. Which number of siblings is least likely?.

Answers

The number 4 siblings are least likely to be selected

What is the number of a sibling to be selected?

Probability is the likelihood of an event occurring or not. Probability value ranges from  impossibility(0) to certainty(1).

The lower the value, the less likely the event is bound to occur.

From the probability distribution table, the probability of having 4 siblings at the game is 0.

This is the lowest out of all the given values in the probability distribution table. Therefore, it is the least likely event.

Thus the number 4 siblings are least likely to be selected

The revenue function for a bicycle shop is given by R(x)=x⋅p(x) dollars where x is the number of units sold and p(x)=800−0.5x is the unit price. Find the maximum revenue.

Answers

Answer:

The maximum revenue is $320,000

Step-by-step explanation:

To find the maximum of a function f, the procedure is as follows:

Find the first derivative of f.Equate the derivative to 0. Solve the resulting equation to get the critical points.Try all the critical points in the original function and select the one that maximizes it.

The revenue function for a bicycle shop is

R(x)=xp(x), where p(x)=800-0.5x. Substituting:

[tex]R(x)=x(800-0.5x)=800x-0.5x^2[/tex]

Find the first derivative of R:

R'(x)=800-x

Equate to 0:

800-x=0

Solve:

x=800

There is only one critical point. Substitute it into the revenue function:

[tex]R(800)=800(800)-0.5(800)^2=320,000[/tex]

The maximum revenue is $320,000

What is the volume of a sphere with a radius of 2.5 units?

Answers

Answer: A sphere (from Greek σφαῖρα—sphaira, "globe, ball") is a geometrical object that is a three-dimensional analog to a two-dimensional circle. A sphere is the set of points that are all at the same distance r from a given point in three-dimensional space. That given point is the center of the sphere, and r is the sphere's radius. The earliest known mentions of spheres appear in the work of the ancient Greek mathematicians.

Step-by-step explanation: The formula used to calculate the sphere radius is: r = ∛((3/4) · V / π) Symbols. r = Sphere radius; V = Sphere volume; π = Pi = 3.14159… The volume of Sphere. Enter the volume contained within a sphere. The radius of Sphere. This is the radius of a sphere that corresponds to the specified volume.

cm.
Round your answer to 1 decimal place.

Help!!!

Answers

Answer:

Step-by-step explanation:

Note:

Circumference of a circle = [tex]\pi d[/tex]

Where d = diameter

We are given the diameter is 20cm, d = 20

Circumference of circle = [tex]\pi d[/tex] = 20 [tex]\pi[/tex]

Also, perimeter of a rectangle = 2 times length + 2 times width

We are told the length = 18 , width = x

Perimeter of rectangle = 2 times 18 + 2 times x

Perimeter of rectangle = 36 + 2x

The question also tells us that the circumference of the circle is EQUAL to the perimeter of the rectangle:

So this means:

Since Circumference of circle = 20[tex]\pi[/tex]  ,

Perimeter of rectangle = 36 + 2x .

We can write:

Circumference of circle = perimeter of rectangle

20[tex]\pi[/tex]   = 36 + 2x

Subtract 36 from both sides

20[tex]\pi[/tex] - 36   = 2x

Divide both sides by 2 to solve for "x".

x = [tex]\frac{20\pi - 36 }{2} = ?[/tex]

Plug it into your calculator and then just round it to 1 decimal place.

How to find the domain of a function

The domain are the input values for which a function exist.

Given the function relating the metal bar is L cm long when its temperature is T◦C as:

L(T) = 0.002T + 25

The domain of the expression is the point where 0.002T + 25 is greater than zero.

0.002T + 25 > 0

The bumper car ride at the state fair has 2 red cars, 3 green cars, and 3 blue cars. Janet is first in line for the ride and is assigned a car at random. Sarah is next in line and is randomly assigned a car. What is the probability that both Janet and Sarah will drive a red bumper car? Express your answer as a percent. If necessary, round your answer to the nearest tenth.
96.4%
25%
6.3%
3.6%

Answers

The probability (in percentage form) is 3.6%, so the correct option is the last one.

How to find the probability?

First, Janet is assigned to a car. We want to find the probability that it is a red car. All the cars have the same probability of being assigned, then the probability of getting a red car is equal to the quotient between the number of red cars and the total number of cars:

p = 2/(8) = 1/4

Now there is 1 red car left and 7 cars in total left.

Sarah is next on line, the probability that she gets a red car will be:

q = 1/7

The joint probability (the probability of both of these events happening) is given by the product of the two individual probabilities, so we get:

P = (1/4)*(1/7) = 0.036

If we multiply this by 100%, we get:

P = 100%*0.036 = 3.6%

So the correct option is the last one.
