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:
No
Step-by-step explanation:
4/6 is also equal to 8/12
9/12 is bigger than 8/12
Answer:
A to B = 2000 m/s
C to D = 30,000m/s
Step-by-step explanation:
A to B is 10secs and the distance is 200m so you multiply them and you get 2000m/s
C to D is 60secs and the distance is 500m so you multiply and you get 30,000m/s
Answer:
The vertical line test can be used to determine whether a graph represents a function. If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because a function has only one output value for each input value.
