Use the equation y-y1 = m(x-x1). Slope = m which can be solved by taking the difference of y and dividing it by the difference of x. Therefore m = 6/-10 which simplifies to -3/5. Then plug m into the equation with either point so for example y-(-5) = (-3/5)(x-19). This then simplifies into y = (-3/5)x + (32/5) which is the final answer.

Answer:

Tera had the higher z-score, so she should be offered the job.

Step-by-step explanation:

Z- score:

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.

In this problem:

Whoever has the higher z-score should get the job.

Brittany:

Scored 88.3, mean 63.1, standard deviation 14. So

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

$Z = \frac{88.3 - 63.1}{14}$
