Answer:
The value of x = 38
Step-by-step explanation:
As we know that
The mean of a data set is the sum of the terms divided by the total number of terms.
Using math notation we have:
Mean = (Sum of terms) ÷ (Number of terms)
As
- Sum of terms = -3 + 10 + 22 + x + 28
so mean the equation becomes
Mean = (Sum of terms) ÷ (Number of terms)
19 = (-3+10+22+x+28) ÷ 5
19 × 5 = -3+10+22+x+28
95 = x + 57
x = 95 - 57
= 38
Therefore, the value of x = 38
