Male and female high school students reported how many hours they spend each week in summer jobs. the data is represented in the following box plots:

The answer is D

Step-by-step explanation:

As you can see by the graph the males line stretches far out compared to the female the box on the line for the males is where the averages are therefore the outlier is about 35

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
