One year terry had the lowest era (earned-run average, mean number of runs yielded per nine innings pitched) of any male pitcher at his school, with an era of 2.85 . also, karla had the lowest era of any female pitcher at the school with an era of 2.95 . for the males, the mean era was 4.893 and the standard deviation was 0.949 . for the females, the mean era was 4.348 and the standard deviation was 0.997 . find their respective z-scores. which player had the better year relative to their peers, terry or karla ? (note: in general, the lower the era, the better the pitcher.)

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8
