Answer:
a) 55%
b) Joint Probability
c) They are not mutually exclusive
Explanation:
Part 1 of the Question
First, we determine the formula for calculating the probabilities of Yellowstone Park and the Tetons as follows
Probability of Yellow Stone = <em>p(</em>Yellowstone)= 0.5 or 50%
Probability of Tetons = <em>p(</em>Tetons)= 0.4 or 40%
Probability of Both = <em>p(</em>Both)= 0.35 or 35%
Therefore, the probability of visiting at least one by a vacationer is as follows:
p(At least One) = <em>p(</em>Yellowstone or Tetons)
= <em>p(</em>Yellowstone) + <em>p(</em>Tetons) - <em>p(</em>Both)
= 50%+40%-35%
= 0.5+0.4-0.35
= 0.55 or 55%
Part 2 of the Question
First the probability of 35% represents the possibility of a vacationer visiting the two locations, hence, it can be called the percentage of intersection between Tetons and Yellowstone. It is also referred to as joint probability
Part 3 of the Question
Once event are mutually exclusive, it means they cannot be carried out or considered together. In other words, one becomes an alternate cost for the other. This means going to Yellowstone means the vacationer cannot go to Tetons and vice versa. In this situation, the joint probability will not be possible (0%). Since, we already know that there is a joint probability of 35%, it means <u>the events are not mutually excusive</u>

Answer:
Comparative Advertising
Explanation:
Comparative advertising is a form of advertising war in which manufacturers compare their products directly or indirectly with competing products. This technique involves comparing product that are similar with the aim of showing the public that the opposite or competing products are inferior to yours. It is done only when the business is at maturity stage. A new start up business cannot go into this form of advertising. Also, it is ill-advised for companies or organizations whose brand are leaders in the markets to go for this kind of marketing, even at maturity stage. The aim of such marketing is usually to put pressure on the leaders of the brand, claiming your products are more superior to theirs.
Answer:
The price of the 1975 golf ball in 2005 is $0.55
Explanation:
In this question, we are asked to calculate the price of a golf ball in the year 2005 which was bought in the year 1975.
Before we begin to answer, we have been seeing CPI, what could this mean?
The term CPI stands for consumer price index. It refers simply to the change in price of a particular goods or services over a specific period of time.
Now, we mathematically propose a solution to the problem as follows;
We identify the following;
CPI in 1975 = 52.3
CPI in 2005 = 191.3
We now calculate the CPI change between the years. This can be done by dividing the CPI in the year 1975 by the CPI in the year 2005. Mathematically;
CPI change between years = CPI IN 1975/ CPI in 2005
= 52.3/191.3
= 0.273
Now, we proceed to calculate the price of the 1975 ball in 2005.
Mathematically;
A 1975 golf ball’s cost in 2005 = CPI change * price of golf ball in 2005
= 0.273 * 2
= $0.55
Answer: $83
Explanation:
Given that,
On 1 June,
Materials purchased = 50 units
Unit price of material = $1.30
On June 15,
Materials purchased = 50 units
Unit price of material = $1.20
Total cost of 65 units:
= (Material purchased on 1 June × Unit price of material) + [(65 units - 50 units) × $1.20]
= (50 units × $1.30) + (15 units × $1.20)
= $65 + $18
= $83
