Answer:
A. The football does not reach a height of 15ft
Step-by-step explanation:
Given

Required
Determine which of the options is true
The option illustrates the height reached by the ball.
To solve this, we make use of maximum of a function
For a function f(x)
Such that:
:

i.e we first solve for 
Then substitute
for x in 
In our case:
First we need to solve
Then substitute
for t in 
By comparison:






Substitute
for t in 






This implies that the maximum height reached is 14.0625ft.
So, the option that answers the question is A because 
Answer: 14.353 or 18.647
Step-by-step explanation:
Hi.
Subtracting:
16.5 - 2.147 = 14.353
Adding:
16.5 + 2.147 = 18.647
Per 1 yard the cost would be $0.38. Not sure what unit you need it in, but thats the answer in yards.
Answer:
The value remain unchanged.
Step-by-step explanation:
By Z score, we mean:
Z =
, if we substitute the given values of mean and standard deviation, we obtain the z score value. That is,
Z =
= 85/12 = 7.083333.
NB: We assume that mean and standard deviation are in the same units.
The answer is : x= -y/3+2
