Question

Find the average of all even numbers from 1to 42

Answer 1

Step-by-step explanation:

Even numbers between 1and 42 are 2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40.

Average = sum of observations/ no of observations = 2+4+6+8+10+12+14+16+18+20+22+24+26+28+30+32+34+36+8+40/20

= 453/20

= 22.65
