The grades on a mathematics midterm are normally distributed with = 71 and o = 4.5. Rob scored 59 on the exam. Find his z-score and write your result in the empty box provided below round to two decimal places.

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5

step-by-step explanation:

a

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
