Answer:
Part A: 5
Part B: 2
Step-by-step explanation:
to find the mean all you have to do is add all the numbers together and then divide it by how many numbers there are in the data set
3+4+4+4+5+6+6+8=40
40÷8=5
so the mean is 5
next to find the mean of absolute deviations you need to subtract each number in the data set from the mean then divide it by how many numbers are in the data set (if you get a negative like 6-5=-1 just take away the negative sign to make it positive)
5-3=2
5-4=1
5-4=1
5-4=1
5-5=0
6-5=-1
6-5=-1
8-5=-3
2+1+1+1+0+1+1+3=10
10÷5=2
so the mean absolute deviation is 2
Answer:
That means Circumference = PI * diameter
Therefore,
PI = Circumference / diameter
Step-by-step explanation:
Answer:
B .57
Step-by-step explanation:
hundredths place is the second decimal place. And because the thousandths place is less than 5, you round down.
Answer:
I think is: x = 344/23
Step-by-step explanation:
It means putting X at the front. So you'd express the equation as x = ay + b
