B because it’s a random sample and it’s not biased
Y= f(x)= ax+b
when x= -1, y= -1
-1= -a+b | * ( -1)
when x= -3, y=2
2= -3a+b
-3a+b= 2
a - b= 1
--------------
2a=3
a=3/2 is the slope
Answer:
5A)36 5b)30(mark as brainliest)
Step-by-step explanation:
5a)6+6+6+6+12 = 36
5b)36-8=28
28+2 = 30
Add them all up, and divide by 10 so 29+38+39+26+29+29+39+77+38+29 which is 33.5
