In an extensive government study conducted this year, a simple random sample of 500 households was obtained and 80 had experienced property damage due to a crime. (b) Last year, it was found that the proportion of households that had been damaged due to crime was 0.20. Based on your interval from part (a), is there convincing evidence that the proportion of households damaged due to crime has decreased from 0.20? Explain.

faster, im not sure why but i know it is faster

answer: it is a.,b.,d.

step-by-step explanation:

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
