A researcher wishes to estimate the percentage of adults who support abolishing the penny, What size sample should be obtained if he wishes the estimate to be within 4 percentage points with 99% confidence it

(a) he uses a previous estimate of 36%?

(b) he does not use any prior estimates?

incomplete question. how do you expect anyone to you when you do not post the question in its entirety?

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!

the answer would be 44.79

step-by-step explanation:

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
