A university's freshman class has 7700 students. 67% of those students are majoring in Engineering. How many students in the freshman class are Engineering majors?

5159 students

Step-by-step explanation:

To find a percentage of a number larger than 100, divide the percent by 100, so 67/100=0.67. Multiply that number by the number that you want to take the percentage of. 0.67 x 7,700 = 5,519

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.

answer: (-6,3)
