Determine whether WXYZ is a parallelogram, a rectangle, a rhombus, or a square for each set of vertices. State yes or no for each and explain why or why not. Show work to support the explanations. For example, if you say the sides are parallel then you need to calculate the slopes. W(-3, -3), X(1, -6), Y(5, -3), Z(1, 0)

If 1/√5+1/√5+1=p+q√r , find the values of p, q 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).
