180 = 2n + 128
2n = 52
n = 26°
180 - 128 = 52
90 + 52 + m = 180
142 + m = 180
m = 38°
Answer: n = 26° and m = 38°
Answer:
Step-by-step explanation:
5y + x = 25
Subtract x from both sides when x = 5
5y + x - x = 25 - x
5y = 20
5y/5 = 20/5
=4
Y=4
Answer: Perpendicular.
Step-by-step explanation:
If you multiply the slopes together you will get -1:

<em>Parallel means they have the same slope, so that is easily ruled out here.</em>
Question A is asking: Considering the distribution shape (i.e skewed left, right, or symmetrical), what measure of center would be used? Explain why that measure of center would be used.
Question B is asking: What measure of variability (or change, i.e range, interquartile range, or standard deviation) would be used for this graph? Explain why this measure would be used.
