Question

The mean of the data x1,x2,x3........xn is 10 .find mean of 5x1 5x2, 5x3..... ........ 5xn.

Answer 1

Answer:

Step-by-step explanation:

Mean=sum of observations / total number of observations

10= x1+x2+x3+.....+xn/n

Multiply the equation with 5

50=5(x1+x2+x3+.......+xn)/n

50=5x1+5x2+5x3+........+5xn/n

Answer is 50

Answer 2

Given; The mean of the data x1,x2,x3........xn is 10

To Find ; 5x1 5x2, 5x3.

Solution; Mean is the average of numbers mean can be defined as the sum of all numbers divided by the number of quantities

mean of given data = 10

x1 + x2 + x3 + x4 .... +xn = 10*n

Mean of 5x1 5x2, 5x3..... ........ 5xn.= 5 (x1 + x2+ x3 ...+ xn )/n

= 5 *10n/n

= 50

Hence the mean is 50
