The vertices of AABC are A (-4.4), B (4.7), and C (-1, 3). What are the coordinates of AA'B'C' and AA"B"C" after reflecting them over the lines x = -3, then y = 5 respectively?

If 1 is divided by the sum of y& 4. the result is equal to 3 divided by 4 .find the value of m?

What is the value of x when x + 7 = 21?

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).
