Table of the graph:
x: <em>
</em>
1 2 3
y: 5 25 125
Average Rate of Change =
Section A = 25-5/2-1 =20/1 =20
Section B = 125 - 25/ 3-2 = 100/1 = 100
So, Section B is 5 times greater than A.
Section B is greater because the slope of two points is greater than points in Section A.
Answer:
Step-by-step explanation:
The standard deviation is the square root of the variance, and the variance is found by using the mean. So we will do that first. I will use the population variance as opposed to the sample variance since our set of numbers is small.
The mean: 8 + 12 + 15 + 17 + 18 = 70 and divide that by 5 to get
and use this to find the variance in the formula:
it is a bit difficult to enter that formula in correctly, but here's how it works mathematically:
Squaring this ensures us that we don't end up with zero, which would be useless.
so
which means that the standard deviation is
s = 3.633
(If you do it with n-1 = 4 in the denominator of the variance, you get a standard deviation of 4.062)
No, she did the right way!!!!!
Answer:
cuz they are chairs
Step-by-step explanation:
Must be in the same units
6 ft/ 24 ft (8yds x 3 = 24 ft)
Let's use yards instead
6 ft = 2 yds
so
2 yds/8 yds again is 1/4
