Below is a chart given for the number of students from different departments in
Technical / engineering college for the year
2019. The proportion of male to female
students in each department is 5:4. There are
40 males in Electrical Engineering. What is
the difference between numbers of female
students in the Civil department and the
female students in the Mechanical
department?

20%
Civil
30%

32

Step-by-step explanation:

From the chart

Male: Female=5:4

Number of Males in Electrical Engineering=40

Let the total population of the student=x

Therefore:

5*0.2x=40*9

x=360

Number of Females in the Civil Department

=48

Number of Females in the Mechanical Department

=16

Difference in the number of females

=48-16

=32

the answer is simply just 6n add the two together as they have an n

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
