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: 900 inches
Step-by-step explanation:
There is 12 inches in a feet so you would have to multiply 12 x 75 and that equals 900.
Answer:
Perimeter = 9x + 12x + 15x
Perimeter = 36x (simplified)
Answer:
second one I believe
Step-by-step explanation:
The slope of Anya’s line on the graph is 3
<h3>How to determine the slope of the line?</h3>
The equation is given as:
(y−2)=3(x−1)
Remove brackets
y − 2 = 3x − 3
Add 2 to both sides
y = 3x − 1
A linear equation is represented as:
y = mx + c
Where m represents the slope;
By comparison, m = 3
Hence, the slope of Anya’s line is 3
