If the fourth term of a geometric progression is
—81/2 and the fifth term is 243/2 find a1 and r ?

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 value of m will create a system of parallel lines with no solution? y = mx - 6 8x - 4y = 12

Solve for x and select the correct answer
