Answer:
B. 1
Step-by-step explanation:
Your answer for A is correct.
The time it take for the sub to hit the water will be the time between when the submarine started to get lowered and when its distance from the water was zero.
The sub started to get lowered at x = 0.
Now we need to solve for the smallest positive zero of the function.
This function factors to (x - 1)(x - 7)
From this we can tell that the submarine is a water level for time x = 1 and x = 7.
The smallest of these is 1, so that is when the submarine first hit the water and 7 is when it came back out.
The sub started getting lowered at x = 0 and hit the water at x = 1 and because x is in seconds, it took 1 second for the sub to hit the water.

The statement that is not true for goodness-of-fit tests is: A. Expected frequencies must be whole numbers.
<h3>What is Goodness-of-fit tests?</h3>
Goodness-of-fit tests can be defined as the test conducted to help find out whether the observe value work hand in hand with expected value or the observe value is different from the expected value.
The statement is not true because it is not must for expected frequencies to be whole number despite the fact that expected frequencies are whole numbers.
Therefore the statement that is not true for goodness-of-fit tests is: A. Expected frequencies must be whole numbers.

Answer:
3.5 hours
Step-by-step explanation:
Use the formula:
distance=rate*time
224=64t
Divide by 64 on both sides
t=3.5
So, it takes 3.5 hours to travel 224 miles
