Step-by-step explanation:
The initial height of the ball is the y-intercept of the function
The initial height she threw the ball from is 35
<h3>How to determine the initial height</h3>
The function is given as:

Set x = 0.
So, we have:

Evaluate the exponent

Evaluate the products

Evaluate the sum

Hence, the initial height she threw the ball from is 35

Answer: The 95% confidence interval is approximately (55.57, 58.43)
======================================================
Explanation:
At 95% confidence, the z critical value is about z = 1.960 which you find using a table or a calculator.
The sample size is n = 17
The sample mean is xbar = 57
The population standard deviation is sigma = 3
The lower bound of the confidence interval is
L = xbar - z*sigma/sqrt(n)
L = 57 - 1.960*3/sqrt(17)
L = 55.5738905247863
L = 55.57
The upper bound is
U = xbar + z*sigma/sqrt(n)
U = 57 + 1.960*3/sqrt(17)
U = 58.4261094752137
U = 58.43
Therefore the confidence interval (L, U) turns into (55.57, 58.43) which is approximate.
Answer:
C
Step-by-step explanation:
Let H = Henry
Let R = Roger
Let S = Sandy
H = 3R -> H = 3y
S = 9 + H -> S = 9 + 3y
R = y
Sandy has 3y + 9 CDs more than Roger.
