Answer 2

Answer:

The mean of the first five perfect squares  = 11

Step-by-step explanation:

Required to find,

The mean of the first five perfect squares

Recall the formula

Mean = $\frac{Sum \ of \ values }{Total \ number\ of \ values}$

Solution

The first five perfect squares are 1²,2²,3²,4²,5²

=1,4,9,16,25

Sum of the first five perfect squares = 1+4+9+16+25

= 55

Total number  of perfect squares = 5

Mean = $\frac{sum \ of \ first \ five \ perfect \ squares}{5}$ = $\frac{55}{5}$ = 11

∴The mean of the first five perfect squares  = 11
