I’m confused on this one

Mekhanik [1.2K]

In this parallelogram, angle A and B add up to 180 (they are supplementary). Set up an equation like this and solve:

3x + 4 + 143 = 180

3x + 147 = 180

3x = 33

x = 11

The measure of x is 11°.

In one town, the number of pounds of sugar consumed per person per year has a mean of 8 pounds and a standard deviation 3 of 20

lesantik [10]

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:

$Z = \frac{X - \mu}{\sigma}$

In which $\mu$ is the mean and $\sigma$ 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:

$\mu = 8, \sigma = 3$

Tyler consumed 13 pounds of sugar last year How many standard deviations from the mean is that?

This is Z when X = 13. So

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{13 - 8}{3}$

$Z = 1.67$

So this is 1.67 standard deviations above the mean.
