Ankit makes 74% of the free throws he takes in his basketball league. If he is fouled on a three-point shot and gets three free throws, what is the approximate probability he will make all three shots?
Answers
The approximate probability that Ankit will make all three shots is 0.405 or 40.5%.
What is binomial distribution?A probability distribution known as the binomial distribution is used to characterize the number of successes in a certain number of independent trials, where each trial has only one of two potential outcomes (success or failure) and the chance of success is constant across all trials. For determining the likelihood of achieving a certain number of successes in a set number of trials, it is utilised.
Given, Ankit makes 74% of the free throws.
Using binomial distribution we have:
[tex]P(X=k) = (n C k) * p^k * (1-p)^{(n-k)}[/tex]
For k = 3 we have:
[tex]P(X=3) = (3 C 3) * 0.74^3 * (1-0.74)^{(3-3)}\\\\P(X=3) = 0.74^3[/tex]
P(X=3) ≈ 0.405
Hence, the approximate probability that Ankit will make all three shots is 0.405 or 40.5%.

A rectangle has a length of 20 inches. if its perimeter is 64 inches, what is the area?
Answers
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf 240 \: {inches}^{2} }}}}[/tex]
Step-by-step explanation:
Given,
Length of a rectangle = 20 inches
Perimeter of a rectangle = 64 inches
Area of a rectangle = ?
Let width of a rectangle be ' w ' .
First, finding the width of a rectangle
[tex] \boxed{ \sf{perimeter = 2(l + w)}}[/tex]
plug the values
⇒[tex] \sf{64 = 2(20 + w)}[/tex]
Distribute 2 through the parentheses
⇒[tex] \sf{64 = 40 + 2w}[/tex]
Swap the sides of the equation
⇒[tex] \sf{40 + 2w = 64}[/tex]
Move 2w to right hand side and change it's sign
⇒[tex] \sf{2w = 64 - 40}[/tex]
Subtract 40 from 64
⇒[tex] \sf{2w = 24}[/tex]
Divide both sides of the equation by 2
⇒[tex] \sf{ \frac{2w}{2} = \frac{24}{2} }[/tex]
Calculate
⇒[tex] \sf{w = 12 \: inches}[/tex]
Width of a rectangle ( w ) = 12 inches
Now, finding the area of a rectangle having length of 20 inches and width of 12 inches
[tex] \boxed{ \sf{area \: of \: rectangle = length \: \times \: \: width}}[/tex]
plug the values
⇒[tex] \sf{area \: of \: rectangle =20 \times 12 }[/tex]
Multiply the numbers : 20 and 12
⇒[tex] \sf{area \: of \: rectangle = 240 \: {inches}^{2} }[/tex]
Hence, Area of a rectangle = 240 inches²

Answers
The correct answer will be option C Randomization of students in morning and afternoon classes.
What is psychology?Psychology is the scientific study of the mind and behavior, according to the American Psychological Association.
The only way to minimize this effect would be through randomization of students in morning and afternoon classes.
Doing so apply the factor of skill from an individual student to either time of day class greatly lessens the overall effect that it has on the results.
This therefore, minimizes the effect it has on the experiment itself, since the same students that have been studying in a certain time of day would be randomized and not have the same environment that they are used to.

The distance from Earth and the troposphere's temperature have a negative association. Interpret the meaning of the negative association with respect to the temperature. As you move closer to the Earth, the temperature decreases. As you move away from the Earth, the temperature increases. As you move closer to the Earth, the temperature remains the same. As you move away from the Earth, the temperature remains the same. As you move away from the Earth, the temperature decreases.

Answers
Answer:
Step-by-step explanation:
- 6x + 9 > 7x + 74
Treat them as being equal first.
Subtract 9 from both sides.
- 6x + 9 - 9 > 7x + 74 - 9
- 6x > 7x + 65
Subtract 7x from each side
- 6x - 7x > 7x - 7x + 65
- 13x > 65
Divide each side by -13
- 13x / -13 > 65 / -13
x < -5
So x hust be smaller than -5 meaning -6 works but -4 doesn't.

3. y= -2
complete the steps used to solve a system of linear equations by substituting the value of y into one of the original equation s to find the value of x. what is the solution to the system
Answer:
x = 3.5
Step-by-step explanation:
We are given;
1. 3(4x - 7y = 28) -> 12x - 21y = 84
-2(6x - 5y = 31) -> -12x + 10y = 62
2. 12x - 21y = 84
-12x + 10y = -62
-----------------------
-11y = 22
3. y= -2
Since y = - 2, let's put -2 for y into the equation; 12x - 21y = 84
This gives;
12x - 21(-2) = 84
This gives;
12x + 42 = 84
12x = 84 - 42
12x = 42
x = 42/12
x = 3.5
