The z-score counts the number of standard deviations from the mean. Then the meaning in gallons of a difference in z-score is found by multiplying the z-score difference by the value of a standard deviation.
(3 -0)*1.2 = 3.6 . . . . gallons.
The 3rd selection is appropriate.
Hello from MrBillDoesMath!
Answer: 8a
Discussion
:
Let's study the expression:
2(5a - 4a) + 6a
The boldfaced term simplifies to "a" as 5 = 4 = 1. So the expression becomes
2a + 6a
As 2 + 6 = 8, 2a + 6a = 8a.

Answer:
W = 2t + 8
Step-by-step explanation:
weight from birth plus number of months times 2 equals your total weight.
We want to write a linear equation for the recipe that describes the amount of oil that we need in terms of the vinegar.
The linear equation is: L = 3*V
So we know that the recipe calls for 1/3 tbsp of vinegar for every tbsp of oil.
Defining:
- V = amount of vinegar used
- L = amount of oil used.
The original equation is written as:
V = (1/3)*L
Now we want to rewrite this for L, this means, isolating L.
To do that we just multiply both sides by 3, so we get:
V*3 = (1/3)*3*L
V*3 = L
L = 3*V
This equation says that we will use 3 times more oil than vinegar.
