Answer:
c. 1.67 standard deviations above the mean
Step-by-step explanation:
The z-score measures how many standard deviations a score X is from the mean. It is given by the following formula:
In which 
is the mean and 
is the standard deviation.
A positive z-score means that X is above the mean, and a negative Z-score means that X i below the mean.
In this problem, we have that:
Tyler consumed 13 pounds of sugar last year How many standard deviations from the mean is that?
This is Z when X = 13. So
So this is 1.67 standard deviations above the mean.
Answer:
definatly not infinitely it should be only one correct answer so false
Step-by-step explanation:
X^2 - 20x = 10
x^2 - 20x + 100 = 10 + 100
(x - 10)^2 = 110
Answer:
First box : 100
Second box: 110

Cube root of n^12 is n^4
Answer:
Step-by-step explanation:
Equation: 
Step 1: Balance both parts of the equation.
Step 2: Reduce 14 from both parts of the equation.
Step 3: Split both sides by 10, because 
.
Therefore, x = -1.
