Answer:
MAD is 5.12
Step-by-step explanation:
The following data were obtained from the question:
42, 50, 54, 38, 48
Next, we shall determine the mean of the data. This can be obtained as follow:
Mean = summation X / n
n is the number of the data.
Summation X = 42 + 50 + 54 + 38 + 48
Summation X = 232
n = 5
Mean = summation X / n
Mean = 232 / 5
Mean = 46.4
Therefore, the mean of the data is 46.4
Finally, we shall determine the mean absolute deviation (MAD) of the data as follow:
MAD = summation |mean – X| /n
MAD = (|(46.4 – 42) + (46.4 – 50) + (46.4 – 54) + (46.4 – 38) + (46.4 – 48|) /5
MAD = |4.4 + 3.6 + 7.6 + 8.4 + 1.6| /5
MAD = 25.6/5
MAD = 5.12
Therefore, the mean absolute deviation (MAD) is 5.12

Answer: g(x) transforms the function so that the graph of the function f(x) shifts vertically by 4 units. For instance, if f(x) is a line intersecting the origin, the transformed function g(x) will be a line with same slope but with a y-intercept at 4.
Answer:
K = 2y + 4
Step-by-step explanation:
Let K = Keith
The numbers should be 2, 2, 5, 9 and 12.
<h3>What is mean, mode and median?</h3>
The arithmetic mean is found by adding the numbers and dividing the sum by the number of numbers in the list.
The median is the middle value in a list ordered from smallest to largest. The mode is the most frequently occurring value on the list.
Let us take numbers 2, 2, 5, 9 and 12.
mean = 30/5
mean= 6
range = 10.
