Find the volume v of the described solid s. the base of s is the region enclosed by the parabola y = 2 − 2x2 and the x-axis. cross-sections perpendicular to the x-axis are isosceles triangles with height equal to the base.

Consider that lines b and c are parallel. what is the value of x? what is the measure of the smaller angle?

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).

What is mean median mode and range?
