Answer:
a) The third quartile Q₃ = 56.45
b) Variance
Step-by-step explanation:
Given that :
= 30.8
Median = 48.5
Mean = 42
a) The mean is less than median; thus the expression showing the coefficient of skewness is given by the formula :
Divide both sides by 1.38
b) The objective here is to determine the approximate value of the variance;
Using the relation
Variance =

Simplify
(((3 • (x3)) + 5x) - ) + 1
3.1 Subtracting a fraction from a whole
Rewrite the whole as a fraction using x as the denominator :
3x^3 + 5x (3x^3 + 5x) • x
3x^3 + 5x = ———————— = ——————————————
1 x
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
4.1 Pull out like factors :

5.1 Adding a whole to a fraction
Rewrite the whole as a fraction using x as the denominator :
1 1 • x

Answer:
c ≈ 40
Step-by-step explanation:
Using the sine ratio in the right triangle
sin40° = =
=
( multiply both sides by c )
c × sin40° = 26 ( divide both sides by sin40° )
c = ≈ 40 ( to the nearest whole number )
