What is the mean absolute deviation of the data set?

Ronch [10]

Answer:

the mean absolute deviation of the data set is 2.

Step-by-step explanation:

To calculate the mean absolute deviation of a data set, we need to follow the following steps:

Step 1: Calculate the mean.

Step 2: Calculate how far away each data point is from the mean (always keeping a possitive distance).

Step 3: Calculate the mean of the deviations.

Step 1: The mean of the data set is:

Mean = (12 + 10 + 10 + 8 + 6+ 7 + 7 + 12)/8 = 72/8 = 9

Step 2:

{12 -9, 10-9, 10-9, 9-8, 9-6, 9-7, 9-7, 12-9} = {3, 1, 1, 1, 3, 2, 2, 3}

Step 3: (3 + 1 + 1 + 1 + 3 + 2 + 2 + 3)/8 = 2

In conclusion, the mean absolute deviation of the data set is 2. Which corresponds to the option B.

In order to store paint, a factory has purchased a cylindrical tank that is 6 feet across and 9 feet deep. What is the maximum n

SOVA2 [1]

Answer:

254 cubic feet.

Step-by-step explanation:

It is given that the a cylindrical tank is 6 feet across and 9 feet deep. It means

Diameter of cylinder = 6 feet

Radius of the cylinder = 6/2 = 3 feet

Height of the cylinder = 9 feet

The volume of a cylinder is

$V=\pi r^2h$

where, r is radius and h is height of the cylinder.

Substitute r=3 and h=9 in the above formula.

$V=\pi (3)^2(9)$

$V=81\pi$

$V=254.46900$

We need to find the maximum number of cubic feet. So approx the value to a whole number.

$V\approx 254$

Therefore, the maximum number of cubic feet of paint the tank will hold is 254 cubic feet.
