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:
The probability of testing positive for one is 0.20.
The probability of testing negative for one sample is (1-0.2)=0.8.
We only save time when all five are negative, which has a probability of 0.8^5=0.32768.
This means that the expected number of tests is
combined sample tests negative = 1 with probability 0.32768
combined sample tests positive = 1+5 retests = 6 with probability 0.67232
Expected number of tests
=Σ nipi / n
=(1*0.32768+6*0.67232)/5 [divide by 5 because we tested 5 samples]
= 0.87232 < 1
So yes, there is a saving.
Note: In practice, all medical tests are not absolute, i.e. they give false-positives(α) and false-negatives (β). The ratios 1-α and 1-β are respectively measures of specificity and sensitivity.
These two parameters complicate the simplistic evaluation above.
Answer:
s = 6
Step-by-step explanation:
We know a square has all equal side lengths. So we would divide the square by four to get one side length.
24/4 = 6
s = 6
