Question

5.1 math find the mean of 40, 40, 40, 44

Explanation:

Step1: Recall the formula for the mean

The mean (average) of a set of numbers is calculated by the formula: $\text{Mean} = \frac{\text{Sum of the numbers}}{\text{Number of numbers}}$.

Step2: Calculate the sum of the numbers

The numbers are 40, 40, 40, 44. So the sum is $40 + 40 + 40 + 44$. Let's calculate that: $40\times3 + 44 = 120 + 44 = 164$.

Step3: Determine the number of numbers

There are 4 numbers in the set.

Step4: Calculate the mean

Using the formula, $\text{Mean} = \frac{164}{4}$. Dividing 164 by 4 gives $41$.

Answer:

41
