One morning at a zoo, there were 165 adults and children who paid to enter. The zoo
collected $1,440 from admission fees. The price of admission is $10 for an adult and $7
for a child.
1. Write the system of linear equations that represents this situation. Let x represent the
number of adults admitted to the zoo and y represent the number of children admitted
to the zoo.

72 is the answer to this problem

probability for j is 1/4

while

a is 1/6

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.
