Formula: y=mx+b
(4,-1)
4 is x
-1 is y
m=1/2
-1=1/2(4)+b
1/2(4)=2
-1=2+b
-1-2=-3
-3=b
y=1/2x-3

Answer:
thirteen hundredths=13/100
one hundred thirty thousandths=130/1000
cancelling by 10 this is =13/100
hence the question
Step-by-step explanation:
<span>Number of values = 5 (There are 5 values given)
Mean = (82 + 44 + 67 + 52 + 120)/5 = 73
Variance = (1/5) [(82-73)^2 + (44-73)^2 + (67-73)^2 + (52-73)^2 + (120-73)^2] = 721.6
Standard deviation = sqrt (721.6) = 26.86</span>
