Question

How is value of 6 number 7 12 17 24 26 and 28 is 1958 is added to each number what will be the new average?

Answer 1

Answer:

Step-by-step explanation:example

from the following data we can assume

f(x,y,z) = ax+by+cz+d

then we get 4 equations and 4 unknown, by solving we get

a= -11/2

b = 15/4

c = 25/4

d = -105/4

Hence we conclude,

f(x,y,z) = -(22x - 15y - 25z + 105)/4

thus f(6,7,7) = 43/4 or 10.75
