Answer:

Due to the higher Z-score, Kamala had the best GPA when compared to other students at her school.

Step-by-step explanation:

Z-score:

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

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

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

In this question:

Whichever student's GPA had the higher z-score had the best GPA compared to other students.

Thuy 2.5 3.2 0.8

This means that $X = 2.5, \mu = 3.2, \sigma = 0.8$

The z-score is:

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

$Z = \frac{2.5 - 3.2}{0.8}$

$Z = -0.875$

Vichet 88 75 20

This means that $X = 88, \mu = 75, \sigma = 20$

The z-score is:

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

$Z = \frac{88 - 75}{20}$

$Z = 0.65$

Kamala 8.9 8 0.4

This means that $X = 8.9, \mu = 8, \sigma = 0.4$

The z-score is:

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

$Z = \frac{8.9 - 8}{0.4}$

$Z = 2.25$

Due to the higher Z-score, Kamala had the best GPA when compared to other students at her school.

If two lines are perpendicular, what is the product of their slopes?

Nadusha1986 [10]

The product of the slopes would be -1 because the slopes of two lines that are perpendicular are opposite reciprocals (ex. 2 and -1/2 multiplied together would be -1)
