Hei, as avea si eu nevoie de putin ajutor la subpunctul c, voiam sa o rezolv cu criteriul clestelui, dar tot obtin 1/2<=In<=1.

The distribution of a sample of the outside diameters of pvc pipes approximates a symmetrical, bell-shaped distribution. the arithmetic mean is 14.0 inches, and the standard deviation is 0.1 inches. about 68% of the outside diameters lie between what two amounts?

Below are two different functions, f(x) and g(x). what can be determined about their slopes? f(x)= −1x + 1 the function g(x) going through 0, 3 and 1, 1

Find the slope of the line that passes through the points (-3, -1) and (0, 3). 3/4 0 4/3
