Iswear i will give 50 points and brainliest here are 10 test scores: 73, 74, 76, 77, 78, 79, 80, 80, 82, 84. the mean of these scores is 78.3. does this set have an outlier and, if so, how does removing it affect the mean?

No it doesnt and if you did have an outlier it would greatly affect the mean because if there was an outlier the mean would move closer to the outlier.

Step-by-step explanation:

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
