The histogram below gives the length of service of members of the department of biology at a particular university. the classes, in years of service, are 0−
−
4.9, 5−
−
9.9, etc., and the vertical axis represents the number of faculty.
what percent of the department faculty have 5 or more years of service?

The percentile is 27 .

Solution:

All the values in the series are in order small to large, ,22, 23, 25, 26, 27, 28, 29, 31, 32, 33, 43, 44, 45, 46, 47, 48, 50, 53

There are total 18 numbers in the problem.

To find the index multiply by 18.

So, the index is

Now counting the data set from left to right i.e, from smallest to largest the 5th number of the series is 27.

Hence, the percentile of the data set is 27.

what are the statements

step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
