Given that average age of employees of a large company is Normal
X - average age of employees
X:N(32,4)
The average age of employees in sales dept is 27 years.
Prob that an employee, chosen at random, will be younger than 27 years.
= P(X<27)
Let us convert x into Z
Z = (x-32)/4 = -5/4 = -1.25
Reqd prob = P(Z<-1.25) =0.5-0.3925
= 0.1075
Hence 10.56% is the correct answer.
" 8 more "....means add 8
" twice a number " means multiply the number by 2
ur expression is : 2n + 8
The answer is 25%
(1)
If 64 is 100%, 48 is how much percent:
64 : 100% = 48 : x
x = 100% * 48 : 64
x = 75
(2)
Percent of decrease is:
100% - x = 100% - 75% = 25%
Answer:
C
Step-by-step explanation:
This one is quite easy. If you look angle M is slightly obtuse which means that it can't be A or B but it is to small to be D.
Answer:
D. y=2x(4×2)
Step-by-step explanation:
y=8 and x=4 and they are asking about the books that Maggie read how they the books re equal to the ones Rahul read. so y will be equal to x times 2 which is also x+x.
Hope I helped!
