Question

find the average of the squares of the first five whole numbers​

Answer 1

Answer:

6

Step-by-step explanation:

First five whole numbers are 0, 1, 2, 3 and 4.

square of these numbers is :

 0² = 0  ; 1² = 1  ;  2² = 4

 3² = 9   ; 4² = 16

Average = sum/no.  of quantities

        = (0 + 1 + 4 + 9 + 16)/5

        = 30/5

        = 6

Answer:

$\large\underline \red{\sf \pmb{Question}}$

• Find the average of the squares of the first five whole numbers

$\large \underline \red{\sf \pmb{Solution}}$

$\purple\bigstar\underline\frak {\pmb{Fistly,Finding \: the \: square \: of \: first \: five \: whole \: numbers }}$

✠ First five whole numbers

• $\mapsto\sf{0, 1, 2, 3, 4}$

✠ Square of first five whole numbers

• $\mapsto\sf{ {0}^{2} = 0 \times 0 = 0}$
• $\mapsto \sf{ {1}^{2} = 1×1 = 1}$
• $\mapsto\sf {2}^{2} = 2 \times 2 = 4$
• $\mapsto\sf {3}^{2} = 3 \times 3 = 9$
• $\mapsto \sf{4}^{2} = 4 \times 4 = 16$

$\purple\bigstar\underline\frak{ \pmb{Now,Finding \: the \: average \: of \: first \: five \: whole \: numbers }}$

$\heartsuit\underline{\boxed{\sf{Average = \dfrac{Sum \: of \: Numbers }{Number \: of \: Units } }}}$

• Substituting the values.

${\implies{\sf{Average = \dfrac{0 + 1 + 4 + 9 + 16 }{5} }}}$

${\implies{\sf{Average = \dfrac{30 }{5} }}}$

${\implies{\sf{Average = \cancel\dfrac{30 }{5} }}}$

${\implies{\bf \purple{Average = 6}}}$

$\heartsuit \large\underline{\boxed{\frak \pink {\pmb {Average = 6}}}}$

• Henceforth,The average of the squares of the first five whole numbers is 6.
