The answer is 67 because 67 x 82 is 5,494 which us close to 5,514
Answer:
The mean absolute deviation of this data
is
.
Step-by-step explanation:
The mean absolute deviation (MAD) of a dataset is the average distance between each data point and the mean. It gives us an idea about the variability in a dataset.
The steps to find the MAD include:
- find the mean (average)
- find the difference between each data value and the mean
- take the absolute value of each difference
- find the mean (average) of these differences
To find the mean absolute deviation of this data
you must
Step 1: Calculate the mean.

Step 2: Calculate the distance between each data point and the mean and take the absolute value of each difference
.

Step 3: Add the distances together.

Step 4: Divide the sum by the number of data points.

Answer:
50
Step-by-step explanation:
.80n = 40
n = 40 divided by .80
40/8/10 = 400 / 80 = 50

Answer:
x = -4
Step-by-step explanation:
The axis of symmetry is the vertical line through the vertex. The vertex is the turning point, or minimum, of the function. It is (x, y) = (-4, 0). The x-coordinate there is -4, so the equation of the axis of symmetry is ...
x = -4
