At a tennis tournament a statistician keeps track of every serve. the statistician reported that the mean serve of a particular player was 98 miles per hour (mph) and the standard deviation of the serve was 10 mph. assume that the statistician also gave us the information that the distribution of the serve speeds was bell shaped. what proportion of the players serves are expected to be between 108 mph and 118 mph?

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

segment bisector

step-by-step explanation:

line segment bisector. definition: a line, ray or segment which cuts another line segment into two equal parts. try this drag one of the orange dots at a or b and note the the line ab always divides the line pq into two equal parts.

answer: a parabola

steps:

(x-1)(x+4)   = x(x+4) - 1(x+4) = (x^2 + 4x) - (x+4)

                = x^2 +4x -x -4   = x^2 +3x -4

which is a parabola
