Question 671:

• WAEC 2019

The distribution of the masses of a group of persons is shown in the following table

Mass/kg	10.5 - 14.4	14.5 - 24.4	24.5 - 44.4	44.5 - 47.4	47.5 - 49.4
Number of Persons	2	6	18	2	1

Draw a histogram for the distribution

Question 672:

• WAEC 2019

Find the angle between $\frac{}{OP}$ = (${}_{-4}^{-3}$) and $\frac{}{OQ}$ = (${}_{-15}^8$)

Question 673:

• WAEC 2019

In the diagram, a mass of 12kg hanging from a light inextensible string is pulled aside by a horizontal force, R, such that the string is inclined at 45${}^o$ to the vertical. If the system is in equilibrium, calculate the;
(a) tension in the string;
(b) value of R

Question 674:

• WAEC 2019

(a). $\frac{T}{\sin {90}^o}$ = $\frac{120}{sin{135}^o}$ and found T = 169.71N
(b) $\frac{R}{\sin {135}^o}$ = $\frac{120}{\sin {135}^o}$
R = 120N

Question 675:

• WAEC 2019

(a) If sin p = $\frac{1}{2}$ and cos q = $\frac{1}{3}$, evaluate sin(p - q), where 0${}^o$ $\ge$ p $\ge$ 90${}^o$ and 90${}^o$ $\ge$ q $\ge$ 180${}^o$

b) Using trapezum rule with seven ordinates, evaluate ${\int }_1^4\frac{2}{\sqrt{x+3}}$dx
