Zoom in on the picture to see it better. The box plots show Theo's math scores and language arts scores.

About 50% of Theo's scores are in which range for each subject?
60 to 85 for math; 60 to 80 for language arts
55 to 90 for math; 50 to 90 for language arts
55 to 60 for math: 50 to 60 for language arts
85 to 90 for math: 80 to 90 for language arts

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

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.
