Answer:
first X=8.94
second X=34
Step-by-step explanation:
5) x^2=4^2+8^2
x^2=16+64=80
x=8.94
6)x^2= 31^2+14^2
x^2=961+196
x^2=1157
x=34
ANSWER
y = 100 + 0.25(160) - equation
y = 140 - if you needed the answer
Mean is average
so we have 4 numbers
sum them then divide by 4
(32+31+37+44)=144
divide by 4
144/4=36
answer is C
I think the mode is 9.875
33•3 is 99, so the answer is 3
