The volume of a cone can be said to be equal to one-third of the volume of a cylinder having the same base radius and height. In general, a cone is a pyramid with a circular cross section. A right cone is a cone with its vertex above the surface.

What is the effect on the graph of the function f(x)=x when f(x) is replaced with -f(x)+4

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).

Does anyone know how to solve and graph this: 4 + | a + 2 | < 7the only part i don't get is the "4 +"
