1. you roll a 6 sided dice. find the probability of rolling a number less than 3. 2. the probability of the dodgers winning the world series is 3/8. the probability of the broncos winning the super bowl is 1/30. calculate the probability that both the dodgers win the world series and the broncos win the super bowl. 3. how many degrees are in a triangle? 4. one angle of a right triangle is measured to be 32 degrees. what is the measure of the other two angles? 5. the hypotenuse of a right triangle is 5 and one leg is 3. what is the measure of the other leg?

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.

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.
