Answer:
See below
Step-by-step explanation:
Circle equation standard form
(x-h)^2 + ( y-k)^2 = r^2 h, k is the center
All are centered at 0,0
radii are sqrt(225) = 15 sqrt 49 = 7 and sqrt 178
The height of the softball when it travels 12 feet using the quadratic regression model is 5.53 foot.
<h3>What is the correlation coefficient?</h3>
Correlation coefficient is used to calculate how strong the relationship is between the two variables.
When there is a statistical relationship between two or more variables, then they are said to be in correlation.
The table represents the distance and height for softball travels after being hit by the batter.
- Distance x (ft) Height y (ft)
- 0 5
- 2 25
- 4 37
- 6 42
- 8 34
- 10 26
- Mean 5 28.167
The mean of the data of distance is 5 and the mean of the data of height is 28.167. The correlation coefficient is 0.9938.
The quadratic regression model for this model is given as,
At the 12 feet, the value of height y is,
Hence, the height of the softball when it travels 12 feet using the quadratic regression model is 5.53 foot.

Answer:
D.
Step-by-step explanation:
CPCTC which stands for "corresponding parts of congruent triangles are congruent". Since ΔMQN and ΔPQN have already been proved congruent, So every angle and sides of these two triangle corresponding with each other would be congruent.
The correct answer is B. Two out of every five people in the shopping center are in the clothing store.
Step-by-step explanation:
To establish this answer we have to know the total number of people that were in the Shopping Center. So, we have to add people from every store.
48+96+20+64+12=240
The result of this operation is 240 people.
Later we have to divide the total number in 5 and multiply by 2.
So, the operation is
240/5 = 48
48x2=96
According to the above, the correct answer is B. Two out of every five people in the shopping center are in the clothing store.
