7. Suppose that the blood cholesterol level of all men aged 20 to 34 follows a normal
distribution with mean y = 188 milligrams per deciliter (mg/dl) and standard deviation o = 41
mg/dl. in an SRS of size 100, find the probability that X estimates y to within t3 mg/dl.

Identify which functions are linear or non-linear. a. f(x) = x2 + 1 b. f(x) = 2x + 5 c. f(x) = x 2 + 3 d. f(x) = 3 x + 7 e. f(x) = 4x + 10 2 - 5

In which direction does the left side of the graph of this function point? f(x) = 3x3 - x2 + 4x - 2

The function y= x - 4x+ 5 approximates the height, y, of a bird, and its horizontal distance, x, as it flies from one fence post to another. all distances are in feet. complete the square to find and interpret the extreme value (vertex). select two answers: one extreme value and one interpretation.
