B. Given the formula d = 90 - 4t represents the amount of water in a 90 gallon fish tank in terms of the number minutes, t, since the tank began to drain.

i. As the number of minutes since the tank began to drain increases from 7 to 13 minutes, the number of
gallons of water decreases
from ___ gallons to ___ gallons.

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x

answer: 5

step-by-step explanation:

since, the range is the difference between the lowest and highest values of the given sample space.

and, here the sample space = { 3, 1, 0, 4, 1, 4, 2, 3, 0, 5, 0, 1, 1, 2, 0, 4, 1,4, 4 ,2 ,3 ,2 ,0 ,1 ,4 }

here, the highest value of the given sample = 5

and, the lowest value = 0

therefore, the range of the sample space = 5 - 0 = 5

do it yourself this is easy
