X = 12
multiply both sides by 12 then expand the brackets and simplify
Answer:
if number of useres are take to be 100(example)
Step-by-step explanation:
total users=100
14% of total users=14
therefore probability=14/100
new probabiltity=(14/100)*(2/10)
15 /6÷ 5/6
when we divide fractions we do the reciprocal of the second number that is of
5/6 = 6/5 and then multiply it by the first number
15/6 x 6/5
ans) 3
Solution :
Let :
X = number of overtime hours
S = total weekly salary
S = 
S = 480 + 18X
E(S) = 

= 750
Mean of S = 750
Var (S) = 
Var(S) = 
= 5184
Variance of S = 5184
The standard deviation equals square root of 5184 = 72
1 1/10
