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.
To solve this problem you must apply the proccedure shown below:
1. You have the following angle given in the problen above:
-230°
2. Then, to f<span>ind the least positive angle measurement that is coterminal with -230°, you must add 360°, as below:
coterminal angle=-230°+360°
coterminal angle=130°
3. Therefore, as you can see, the answer is: 130°</span>
