Which statement best describes the use of a simulation to predict the probability that two randomly chosen people will both have their birthdays on a Monday? Randomly generate an integer from 1 to 2 seven times, and the probability is StartFraction 1 over (2) (7) EndFraction. Randomly generate an integer from 1 to 2 seven times, and the probability is StartFraction 1 over 2 Superscript 7 Baseline EndFraction. Randomly generate an integer from 1 to 7 two times, and the probability is StartFraction 1 over (2) (7) EndFraction. Randomly generate an integer from 1 to 7 two times, and the probability is StartFraction 1 over 7 squared EndFraction.

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.

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
