Jayana is trying to run 30 miles by the end of the months.
30% / 100% = 9 / x
9 * 100 = 900
900 / 30 = 30 miles
So, let's make these two values improper fractions so they're easier to work with. 
So, to get the rate he grew in those months we have:
And to get the rate he grew in one month we have to divide both our numerator and our denominator by 21 to get:
aka he grew 1.24 inches in a month.
a constant of proportionality is a number you have to multiply x by to get y.
y=kx is the equation that expresses the proportionality of x and y
the constant of proportionality is k, so k=-5
Answer:
Absolute deviation is when you find the mean of a data set, then the difference between each number and the mean, then the average f the differences.
Step-by-step explanation:
Maddox: |10-9| = 1
Enrique: |10-13| = 3
Gloria: |10-9| = 1
McKenna: |10-10| = 0
Asher: |10-9| = 1
Hannah: |10-9| =
Danielle: |10-10| = 0
Katy: |10-10| = 0
Timothy: |10-11| = 1
Gentry: |10-9| = 1
Now you have the numbers: 1, 3, 1, 0, 1, 1, 0, 0, 1, 1,
Now find the mean of those numbers:

The absolute deviation is 1.
Answer:
7.5%
Step-by-step explanation:
86 - 80 / 80 = 0.075
so 7.5%
