Find the sum of (8a+2b-4) and (3b-5)

Acylinder has volume 45π and radius 3. what is it’s height?

Atextile fiber manufacturer is investigating a new drapery yarn, which the company claims has a mean thread elongation of 12 kilograms with a standard deviation of 0.5 kilograms. the company wishes to test the hypothesis upper h subscript 0 baseline colon mu equals 12 against upper h subscript 1 baseline colon mu less-than 12 using a random sample of n equals 4 specimens. calculate the p-value if the observed statistic is x overbar equals 11.8. round your final answer to five decimal places (e. g. 98.76543).

Which expression do you get when you eliminate the negative exponents of 4a^2 b^216a^-3 b
