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: PMI will automatically be dropped when the balance reaches $117,000.
Explanation: PMI stands for private mortgage insurance. This is an insurance policy that banks often require lenders to have when they do not have a 20% down payment on a new home.
PMI is automatically dropped with the amount of the mortgage due is reduced to 78% of the original appraised value of the home. In this case, the home was originally purchased for $150,000. 78% x 150,000 = $117,000. When the loan reaches $117,000 the pmi will automatically be dropped.
Answer:
C. By realizing gains through increase in share price and cash divideneds.
Explanation:
For most corporations, the management must strive to ensure the firm is doing well in the market space. Once a company is doing well, it will affect its share price positively on the stock exchange.
An increase in the share price of fim is a gain to the firm and its corporate owners. I.e sharedholders. This means that the value of their investment in the firm has appreciated.

Answer:
The price of a Dinner= $6.22
Explanation:
<em>Mark-up is the proportion of the product cost which is expected to be made as profit. In other words, it is profit expressed as a percentage of product cost.</em>
To account for the spoilage rate of 10%, $3.50 unit cost would be consider as 90% of the cost. Thus, 100% of the cost would be given as follows:
Dinner cost = 100/(100-10)× 3.50= 3.89
The price of a Dinner = product cost + 60% of product cost
The price of a Dinner = 3.89 + 60%*3.89= $6.22
The price of a Dinner= $6.22
According to Quora dot com, US magazines are viewed as historically dependent on advertising revenue hence why subscriptions to magazines are historically very low as advertising is used to subsidise cover price or subscription cost.
With the general collapse of print publications in the US, particularly led by the drying up of physical newsstand presence, magazines have a harder time getting into consumer's hands. This means that advertisers are less likely to spend in a publication (readership decreasing) and then advertising revenues go down, making magazines less and less profitable.
I realize this is quit lengthy so I'd sum it up to saying the business model for magazines has traditionally been the selling of advertising space ... Not sure if this is what you're looking for
