Answer:
let's see what to do buddy....
Step-by-step explanation:
The mean of the 10 values denoted x equals 7.4
So we have :
[tex] \frac{x(1) + x(2) + x(3) + ... + x(10)}{10} = 7.4 \\ [/tex]
Multiply the sides of the equation by 10 :
[tex]10 \times \frac{x(1) + x(2) + x(3) + ... + x(10)}{10} = 7.4 \times 10 \\ [/tex]
After do that we have :
[tex]x(1) + x(2) + x(3) + ... + x(10) = 74 \\ [/tex]
Which means we have the sum of all values.
And we're done...
Thanks for watching.
