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.
The coordinates of the endpoints of the range can be used to calculate the rate of change using the slope formula: m = dy / dx. The coordinates are (pi, -1) and (3pi/2, 2). So, dy = 3pi/2 - pi = pi/2 and dx = 2 - (-1) = 3. Therefore, m = pi/6.
