By the empirical rule, 84% of the distribution is below one standard deviation above the mean.
16% of Ed's monthly phone bills are more than $76.
Multiply it all together 3/4 is 0.75 2/3 is 0.66 1/2 is 0.5 now do in your calculator 0.75+0.66+0.5 and becase everything is in fractions remember that you have to convert your decimal into a fraction your answer is 1 91/100
It's 9. (I don't use inches in Canada but I made everything in inches so hopefully it helped)
Answer:
C. He should have added t instead of subtracting t.
Step-by-step explanation:
We know that measure angle PQS = 112 degrees.
From the drawing, we can see that:
measure angle PQR + measure angle RQS = measure angle PQS
72 + 10x = 112
10x = 112 - 72
10x = 40
x = 4
