Answer:
Total amount = R5112
Step-by-step explanation:
Let the cooks be C.
Let the waiters be W.
Given the following data;
Number of cooks, C = 2
Number of waiters, W = 3
a. To find the amount earned by each cook;
C = 36 * R36 = R1296
b. To find the amount earned by each waiter;
W = 30 * R28 = R840
c. To find the total amount earned by the employees;
Total amount = 2C + 3W
Total amount = 2(1296) + 3(840)
Total amount = 2592 + 2520
Total amount = R5112

The semicircle shown at left has center X and diameter W Z. The radius XY of the semicircle has length 2. The chord Y Z has length 2. What is the area of the shaded sector formed by obtuse angle WXY?

RADIUS = 2
CHORD = 2
RADIUS --> XY , XZ , WX
( BEZ THEY TOUCH CIRCUMFERENCE OF THE CIRCLES AFTER STARTING FROM CENTRE OF THE CIRCLE)

THE AREA OF THE SHADED SECTOR FORMED BY OBTUSE ANGLE WXY.

AREA COVERED BY THE ANGLE IN A SEMI SPHERE


Total Area Of The Semi Sphere:-

Area Under Unshaded Part .
Given a triangle with each side 2 units.
This proves that it's is a equilateral triangle which means it's all angles r of 60° or π/3 Radian
So AREA :-


Total Area - Area Under Unshaded Part


Answer:
k
Step-by-step explanation:
Answer:
65.3%
Step-by-step explanation:
Binomial distribution PMF below (along with a description)
the probabilty of getting 2, 3, or 4 successes in 5 trials is just
p(2)+p(3)+p(4)
p(2)= 5C2*.4²*(1-.4)³ = .3456
p(3)= 5C3*.4³*(1-.4)²= .2304
p(4)= 5C4*.4⁴*(1-.4)=.0768
.3456+.2304+.0768= .6528
