Question

How to find x if the mean is 8, x, 4.5, 6.7, 2.7, 10.

Options:
Option 1: x = 6.7
Option 2: x = 5.4
Option 3: x = 7.2
Option 4: x = 6.0

Answer 1

To find the value of x, calculate the mean of the given set of numbers. The mean is the average value, which can be found by summing all the numbers and dividing by the total count.

Step-by-step explanation:

To find the value of x, you need to calculate the mean of the given set of numbers. The mean is the average value, which can be found by summing all the numbers and dividing by the total count. In this case, the mean is (8 + x + 4.5 + 6.7 + 2.7 + 10) divided by 6. This simplifies to (8 + x + 4.5 + 6.7 + 2.7 + 10) / 6 = 8. Rearranging the equation, we get (x + 32.9) / 6 = 8. Multiplying both sides by 6, we have x + 32.9 = 48. Subtracting 32.9 from both sides, we find x = 15.1. Therefore, the correct option is x = 15.1.
