Answer:
The mean absolute deviation = 3.5°F
Step-by-step explanation:
The sum of the given temperatures, ∑T, is found as follows;
∑T = 66°F + 57°F + 61°F + 65°F + 54°F + 62°F + 59°F + 56°F = 480°F
The number of days, n, over which the temperature was tracked = 8 days
Therefore, the mean, 
, of the data set = ∑T/n = 480°F/8 = 60°F
The mean absolute deviation is given by the following formula;
Therefore, we have;
66 - 60 = 
= 6
57 - 60 = 
= 3
61 - 60 = 
= 1
65 - 60 = 
= 5
54 - 60 = 
= 6
62 - 60 = 
= 2
59 - 60 = 
= 1
56 - 60 = 
= 4
The mean absolute deviation is therefore;
The mean absolute deviation = (6 + 3 + 1 + 5 + 6 + 2 + 1 + 4)/8 = 3.5°F.
Answer:
w = 
Step-by-step explanation:
The question is 
We can first use distributive property to simplify, the distributive property is 
Thus we have:
<em>Now we combine like terms and simplify to get the final answer for w</em><em>.</em>
Thus, w =
First, you add like terms. In this case, the like terms are 6 and 3.
4x + 6 + 3 = 17
4x + 9 = 17
Then, subtract 9 on each side:
4x + 9 - 9 = 17 - 9
4x = 8
Then divide by 4 on each side to get the x by itself:
4x/4 = 8/4
x = 2
A OK this was hard very hard
Its B, breed 1 dogs and breed 2 dogs have somewhat similar weight distributions
