<u>Solution and Explanation:</u>
a) 51% of users of mobile phones use their phone at least once per hour,
It is a binomial distribution with n = 150, p = 0.51
mean = np = 150 multiply with 0.51 = 76.5
SD= sqrt(np(1-p) )= 6.1225
Since np and n(1-p) > 5, we can assume the distribution is normal.
B) please see the attached file.
c) It is a binomial distribution with n = 150, p = 0.02
mean = np = 150*0.02 = 3
SD= sqrt(np(1-p) )= 1.71464
Since np < 5, we cannot assume the distribution is normal.
Answer:
$250,000
Explanation:
The depreciable cost of the equipment is the amount that will be used to provide for depreciation on the asset also known as Depreciable Amount.
<em>Depreciable Cost = Cost - Salvage Value</em>
therefore,
Depreciable Cost = $300,000 - $50,000 = $250,000

Answer:
The type of action that asks how and why performance deviated is called BASIC CORRECTIVE ACTON.
Explanation:
Basic corrective action are Corrective action that looks at how and why performance deviated before correcting the source of deviation.
Basic Corrective Action - Essential restorative activity that takes a gander at how and why execution veered off before remedying the wellspring of deviation. It's not unusual for supervisors to legitimize that they don't have opportunity to discover the wellspring of an issue (fundamental restorative activity) and keep on ceaselessly "put out flames" with prompt remedial activity.
Answer:
a) 
b) 
c) For this case we have the total sales $ 15 millions after t =4 months
d) 
e) This value represent the increase in the amount of sales in millions after t=4 months
Explanation:
For this case we have the following function for the sales

Part a
For this case we want to find the derivate of S respect to t and we got:

Part b
For this case we want to find the value of S when t = 4 so if we replace we got:

Part c
For this case we have the total sales $ 15 millions after t =4 months
Part d
For this case we just need to replace t=4 in the derivate and we got:

Part e
This value represent the increase in the amount of sales in millions after t=4 months
