Question

If the mean value of (x,y,z) is 10, what is the mean value of (5x,5y,5z)?

Answer 1

Answer:

The mean would be 150

Step-by-step explanation:

mean = (x + y + z)/3= 10

therefore (x + y + z) = 30

5x + 5y + 5z = 5(x + y + z) = 5(30)=150..

Answer 2

x+y+z/3 = 10 -Equation 1

5x+5y+5z/3

5 ((x+y+z)/3) - Equation 2

Sub Equation 1 in 2

5*10= 50

ANSWER is 50
