In a nursery class of 18 pupils, the average is 4<img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20" id="TexFormula1"

Alisiya [41]

Answer:

The sum of ages of all 18 pupils in the class = 81

Step-by-step explanation:

Total number of pupil in the class = 18

Average of years in the class = $4\frac{1}{2}$

Now, $4\frac{1}{2} = 4 + \frac{1}{2} = 4 + 0.5 = 4.5$

⇒Average of sum of ages in the class = 4.05

Let us assume the sum of ages of all students in the class = m

By the formula for AVERAGE:

$\textrm{Average of n obseravtions} = \frac{\textrm{Sum of n observations}}{\textrm{n}}$

$\implies 4.5 = \frac{m}{18}$

or, m = 18 x 4.5 = 81

Hence, the sum of ages of all 18 pupils in the class = 81

Find the distance between the points. Give an exact answer and an approximation to three decimal places.

Nimfa-mama [501]

Answer:

The distance between the points is $d=2\sqrt{5}\ units$ or $d=4.472\ units$

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

we have

$(7,-3)\\(5,1)$

substitute the values

$d=\sqrt{(1+3)^{2}+(5-7)^{2}}$

$d=\sqrt{(4)^{2}+(-2)^{2}}$

$d=\sqrt{20}\ units$

$d=2\sqrt{5}\ units$ ----> exact answer

$d=4.472\ units$ -----> approximation to three decimal places
