The arithmetic mean is calculated by adding all the observations and dividing by the number of observations.

Explanation

We are given: (-2x)^3

To solve this, we need to cube both -2 and x separately:

(-2)^3 * x^3

Calculating the cube of -2:

(-2) * (-2) * (-2) = -8

So, the expression becomes:

-8 * x^3

Explanation

The range of a data set is calculated as the difference between the maximum value and the minimum value:

$$\text{Range}=\text{Maximum value}-\text{Minimum value}$$

Given:

• Minimum value = 5
• Range = 50

Substitute these values into the formula:

$$50 = text{Maximum value} - 5$$

Solving for the maximum value:

$$\text{Maximum value}=50+5=55$$
