Step-by-step explanation:
i am unsure of what you actually need, but i want to help you.
if you were to set the boundaries of the feasibility region it would be as follows:
as points
A(1, 17/3) B(7, 11/3) C(7, infinity) D(1, infinity)
as graphs
y=-1/3x+6 where 1≤x≤7
x=1
x=7
Answer:
Step-by-step explanation:
Remark
You have 2 points to solve the equation y = mx + b. After finding m, use either of the points to find b.
Formula
y = mx + b
m = (y2 - y1)/(x2 - x1)
Solution
- y2 = 13
- y1 = 5
- x2 = 0
- x1 = 24
m = (13 - 5)/(0 - 24)
m = 8 / - 24
m = - 1/3
y = mx + b
y = -1/3 x + b
Use (0,13) as the point.
13 = -1/3 * 0 + b
13 = b
The y intercept = (0,13)
Answer:
a) 0.9
b) Mean = 1.58
Standard Deviation = 0.89
Step-by-step explanation:
We are given the following in the question:
A marketing firm is considering making up to three new hires.
Let X be the variable describing the number of hiring in the company.
Thus, x can take values 0,1 ,2 and 3.
a) P(firm will make at least one hire)
Also,
b) expected value and the standard deviation of the number of hires.
