Select the most appropriate answer. when a higher confidence level is used to estimate a proportion and all other factors involved are held constant there is not enough information to determine the effect on the confidence interval. the confidence interval will be less likely to contain the parameter being estimated. the confidence interval will be narrower. the confidence interval will not be affected. the confidence interval will be wider. provide an appropriate response. in a recent study of 42 eighth graders the mean number of hours per week that they watched television was 19.6 with a standard deviation of 5.8 hours. find the 98% confidence interval for the population mean (19.1, 20.4) (18.3, 20.9) (14.1, 23.2) (17.5, 21.7) provide an appropriate response a 95% confidence interval for a population mean has a margin of error of 3.9. if the sample mean is 54.6 obtain the 95% confidence interval from 50.7 to 54.6 from 46.8 to 62.4 from 50.7 to 58.5 from 52.64 to 56.56 from 46.96 to 62.24

the factors of 24 are 1, 2, 3, 4, 6, 8, 12 and 24. hope this ! mark brainliest! you v much! : )

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!
