Question

If the mean of the data below is 3.8 find m. x 1 2 3 4 5 6 y 2 4 7 m 6 3​

Answer 1

Answer:

m = 0.8

Step-by-step explanation:

The mean can be calculated as:

$\frac{2 + 4 + 7 + m + 6 + 3}{6} = 3.8$

Then, all the values can be added and the expression turns into:

$\frac{22 + m }{6} = 3.8$

The expression can be simplified by multiplying on both sides by 6:

$\frac{22 + m }{6}*6 = 3.8*6$

$22 + m = 22.8$

Which makes m = 0.8
