Answer: Intersect at one point and exactly one solution.
Step-by-step explanation: I answered it right now in the assignment and it was correct.
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.

We are given that the surface area A is:
A = 5.2 ft^2
To convert this into in^2, we know that there are 12
inches in 1 feet, so 12 in = 1 ft:
A = 5.2 ft^2 * (12 in / 1 ft)^2
<span>A = 748.8 in^2</span>
180/3=60
Now lets find out what x is the get 5x+10 to equal 60.
Just looking at it, its D.....x=10
5(10)+10
50+10=60

Answer:
20 feet
Step-by-step explanation:
1/2" = 4 feet
1" = 8 feet
2" = 16 feet
2 1/2" = 20 feet
