1. Suppose that to make the golf team you need to score no more than 85 on average over 5 games. If you scored 97, 76, 84, and 68 in your first 4 games, what is the highest score you can shoot in your 5th and final game and still make the team?

2. A store sells 5 models of cameras for $400, $320, $480, $350, and $320. If the sales tax rate is 11%, what are the mean, median, mode, and range of the total cost of the cameras?

the correct answer is 5 6 and 7

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.

the first option i believe
