Write an equation of the perpendicular bisector of the segment with endpoints U(-3,4) and V(9,8)

stealth61 [152]

Answer:

y=-3x+15

Step-by-step explanation:

the midpoint of UV (using the midpoint formula) is (3,6)

the slope of UV= 4/12= (1/3)

perpendicular slope is -3

now find line with slope -3 passing (3,6)

y-6=-3(x-3)

y=-3x+15

Patrisse and Makayla began arguing about who did better on their tests, but they couldn't decide who did better given that they

hodyreva [135]

a) Z-score for Patrisse test grade is 0.7288

b) z-score for Makayla test grade is -0.7441

c) Patrisse did better.

<h3>What is z- score?</h3>

A Z-score is a numerical measurement that describes a value's relationship to the mean of a group of values.

Z-score for Patrisse test grade.

X= 81.4, $\mu$ = 72.8, $\sigma$ = 11.8

Z= x- $\mu$ / $\sigma$

Z= 81.4 - 72.8/ 11.8

Z= 0.7288

Now, z-score for Makayla test grade.

X= 60.6, $\mu$ = 67, $\sigma$ = 8.6

Z= x- $\mu$ / $\sigma$

Z= 60.6 - 67/ 8.6

Z= -0.7441

Hence, Patrisse did better as she had better z- score.
