Answer:

Step-by-step explanation:

Ok, this is an easy one. Step one: Find the Mean of the numbers by adding all the numbers 21, 45, 21, 14, 21, 28, 14, 24, and 28 which you will get according to my answer 220. Then you divide that by 9 since that there are 9 numbers listed above. When you divide you will get about 24.4 since you want it to be rounded to the neared tenth. Then you subtract 24.4 to all the number and when you get your answer, put the answer as |-3.4| for the first one so you will get a positive instead of a negative which is what we want. The second will be |20.6| which is 20.6 ans so on when we subtract. Then when you get all of that, you will need to add all those numbers and get a number and divide that by 9 because again there are 9 numbers. Now that you know that, you can do part b and c. Interpret means to depict something. For part C, you will need to use part A again and find the mean absolute deviation for part A again but without 45. And then explain the difference and how it affects the answer. To help with that, compare the 2 answers.

1. -88 = -3(4m + 5) - (1 - 3m)​
Vadim26 [7]

Answer:

m=8

Step-by-step explanation:

-88=-3(4m+5)-(1-3m)

-88=-12m-15-(1-3m)   <- Distributive Property

-88=-12m-15-1+3m  <- Open () if there is a negative negative the symbol equals positive

-88=-9m-16    <- Simplify

0=-9m+72   <- Add 88 to both sides

9m = 72 <- Add 9m to both sides

9m = 72

/9      /9

m=8
