Marietta has three random samples of the same size from a population of 500 people. In one sample, 50% of people have a wand. In another, 45% of people have a wand. In the third, 40% have a wand.
Based on the three samples, how many people with a wand should he expect are in the population?

kk.bj.

step-by-step explanation:

.mnm.kn.kj

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.

∠cbe and ∠deb are same-side interior angles.
