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.
Answer:
6
Step-by-step explanation:
First, subtract 9 on both sides:
d+9-9=15-9
d=6
Hope this helped!
Answer:
131˙
Step-by-step explanation:
Supplementary angles are angles that add up to 180˙. If you subtract 49 from 180, you get 131.

For this case, the first thing to do is to graph the following ordered pairs:
(-6, -1)
(-3, 2)
(-1,4)
(2,7)
We observe that the graph is a linear function with the following equation:
y = x + 5
Note: see attached image.
Answer:
The function that best represents the ordered pairs is:
y = x + 5
