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.
The graph that would easily allow us to see the increase or decrease of persons or individuals owning cellphone/s from 2000 to 2007, we could use bar graph. This bar graph represents the grouped data in rectangles and the number in y-axis would be shown to differ through the lengths of the bars.
Step-by-step explanation:
recommended is to convert to decimal
1/5 is 0.2
1/2 is 0.5
1/3 is 0.33
Order is 1/5, 1/3, 1/2
B
The purple balls constitute 1/3 of the amount of balls there, so you’re that likely to pluck one out.
Answer:
67°
Step-by-step explanation:
Angles on a straight line add to 180, so:
A + D = 180
D = 180 - A
D = 180 - 113
D = 67
