A=  Accident caused by blue cab    B= witnesses told the cab was blue.It is easy and straightforward to have probability of P(A)= 15% and P(B/A) is 85%. Following the law of total probability.<span><span><span>P(D)</span><span>=P(D|H)P(H)+P(D|<span>¯H</span>)P(<span>¯H</span>)</span></span><span> <span>=0.8⋅0.15+0.2⋅0.85=0.29</span></span></span>Therefore I get <span>P(H|D)=41%</span>. Thus, even if the witness said that the cab involved in the accident was Blue, the probability of this being true is only <span>41%</span>.

Why is price important to a company?
alukav5142 [94]

Answer:

B. It is a part of the marketing mix.

Explanation:

Price refers to the amount of money a customer or consumer buying goods and services are willing to pay for the goods and services being offered. The price of goods and services are primarily being set by the seller or service provider.

Price is important to a company because it is a part of the marketing mix.

Generally, a marketing mix is made up of the four (4) Ps;

1. Products: this is typically the goods and services that gives satisfaction to the customer's needs and wants. They are either tangible or intangible items.

2. Price: this represents the amount of money a customer buying goods and services are willing to pay for it.

3. Place: this represents the areas of distribution of these goods and services for easier access by the potential customers.

4. Promotions: for a good sales record or in order to increase the number of people buying a product and taking services, it is very important to have a good marketing communication such as advertising, sales promotion, direct marketing etc.

Price is generally considered to be a variable in the marketing mix that is most flexible because unlike other elements of production, it can be easily changed. An organization can decide to either raise or lower it's price depending on the nature of the market.

A student borrows $95,000 for business school at 4.5% stated annual interest with monthly repayment over 9 years. Consider this
Damm [24]

Answer:

$918.70 or $900

Explanation:

The computation of the first monthly payment is given below:

Interest rate per Month is

= Annual Rate ÷ 12

= 4.50% ÷ 12

= 0.375%

Now

Present Value of Growing Annuity = First payment × (1 - ((1 + Growth Rate) ÷ (1 + Interest Rate))^Periods) × 1 ÷  (Interest Rate - Growth Rate)

95000 = First payment × (1 - ((1 + 0.30%) ÷ (1 + 0.375%))^108) × 1 ÷ (0.375% - 0.30%)

95000 = First payment × (1 - 0.999252^108) × 1 ÷ (0.075%)

95000 = First payment × (1 - 0.92244) × 1 ÷ (0.075%)

95000 = First payment × 103.4067

First payment = $918.70 or $900
