The amount of water for washing x cars is y = 12x, and 72 gallons would be needed to wash 6 cars.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

The standard form of a linear equation is given as:

y = mx + b

Where m is the rate of change and b is the y intercept (initial value of y)

Let y represent the amount of water Jaquan uses to wash x cars, Using the point (2, 24) and (5, 60):

y - 24 = [(60 - 24)/(5- 2)](x - 2)

y = 12x

For 6 cars:

y = 12(6) = 72

The amount of water for washing x cars is y = 12x, and 72 gallons would be needed to wash 6 cars.

Answer:

Null hypothesis: There is no relationship between direction of the ball and if it resulted in a hit or an out.

Step-by-step explanation:

In this case, the experiment conducted is to determine whether there is any relationship between the direction of the ball and if it resulted in a hit or an out.

A random sample of 300 balls hit into play in college baseball games is taken. For each ball hit into play, it is recorded whether the ball was hit to the left, center, or right of the field, and whether the ball resulted in a hit or an out.

The regression analysis would be used to determine whether there is any relationship between direction of the ball and if it resulted in a hit or an out.

The hypothesis for the regression analysis is defined as follows:

<em>H</em>₀: There is no relationship between direction of the ball and if it resulted in a hit or an out.

<em>H</em>ₐ: There is a significant relationship between direction of the ball and if it resulted in a hit or an out.

Can someone please help me with this

Alright!

To solve, all we need to do is <em>subtract the area of the inner circle from the arear of the outer circle.</em>

But first, we need to find the area of both

Key equation: πr²

π = 3.14

Inner cirle area = π13²

π13² = 530.66

Outer cirle area = π21²

I got 21 by adding 8 and 13: both added together makes the radius of the larger circle

π21² = 1,385.74

Now let's <em>subtract. </em>

1,385.74 - 530.66 = 855.08

The area of the blue is = 855.08 yards²
