The price of products may increase due to inflation and decrease due to depreciation. Derek is studying the change in the price

of two products, A and B, over time.
The price f(x), in dollars, of product A after x years is represented by the function below:

f(x) = 0.69(1.03)x

Part A: Is the price of product A increasing or decreasing and by what percentage per year? Justify your answer. (5 points)

Part B: The table below shows the price f(t), in dollars, of product B after t years:




t (number of years)
1 2 3 4

f(t) (price in dollars)
10,100 10,201 10,303.01 10,406.04

Which of the following is true of analogies in supporting problem solving?
iVinArrow [163]

Answer:

  • B) Relevant analogies often assist individuals in problem-solving, though people usually do not instinctively consider relevant analogies.

Explanation:

An analogy establishes a connection between two situations, highlighting similarities or points of comparison.

Indeed, analogies are valuable in resolving problems. At times, a dilemma may appear intricate and hard to grasp, but it is possible to relate the situation to another, for which the solution is more straightforward. Once you identify the answer to the simpler issue, you can apply similar reasoning to resolve the original question.

Conversely, identifying relevant analogies can be challenging, necessitating tips, clues, or hints that help bridge the two seemingly disconnected problems. Upon discovering the link, the more obvious solution to the less complicated issue can then be utilized to tackle the more complex one.

kotykmax [209]

Answer:

Regarding the nature of a Case Study:

E. The conclusions can be generalized to represent a whole population.

Explanation:

A case study conducts an in-depth examination of an individual, group, situation, or event to illustrate a specific principle that can be generalized across a larger population.

Case study findings have significantly impacted fields such as business, management, psychology, anthropology, sociology, political science, education, clinical science, social work, and administrative science. For instance, a physician might consider a patient as a case study to explore a illness, its treatment, and its results. This knowledge can then be applied to treat subsequent patients.

Kathy and her brother Clay recently ran in a local marathon. The distribution of finishing time for women was approximately norm
zhannawk [148]

Answer:

Approximately 66% of women who participated in the marathon finished with a time faster than Kathy's (rounded to the nearest whole number)

Explanation:

1. To analyze this correctly, let's go over the provided data:

The average finishing time for women = 259 minutes

Standard deviation of finishing time for women = 32 minutes

Kathy's finishing time = 272 minutes

2. To find the proportion of women who ran the marathon with times less than Kathy's, we will calculate the z-score for her finishing temperature as follows:

z-score = (272 - 259)/32

z-score = 13/32 = 0.41 (rounded to the nearest hundredth)

Using the z-table, we can now determine the proportion of women who completed the marathon in less time than Kathy:

p(z=0.41) = 0.6591

About 66% of women who completed the marathon had a quicker finishing time compared to Kathy's (rounded to the nearest whole)
