Company F sells fabrics known as fat quarters, which are rectangles of fabric created by cutting a yard of fabric into four pieces. Occasionally the manufacturing process results in a fabric defect. Let the random variable X represent the number of defects on a fat quarter created by Company F. The following table shows the probability distribution. If a fat quarter has more than 2 defects, it cannot be sold and is discarded. Let the random variable Y represent the number of defects on a fat quarter that can be sold by Company F. (a) Construct the probability distribution of the random variable Y

Answers

From the given information given, the mean and standard deviation of the probability distribution is; Y will be 0.4899 and 0.699 respectively.

How to create the probability distribution?

From the given probability distribution, it should be noted that the probability distribution for y will be:

Y                   0        1.         2

Probability 0.63.   0.25.   0.12

The mean of Y will be:

Mean = (0 × 0.63) + (1 × 0.25) + (2 × 0.12)

Mean = 0 + 0.25 + 0.25

Mean = 0.49

The variance will be 0.4899. Therefore, the standard deviation will be:

Answers

Based on Marc and Jean's investment priorities and risk tolerance, we will assign most of their portfolio to High-risk stocks and real estate.

How should Marc and Jean's portfolio be allocated?

Marc and Jean will be assumed to be young which likely means that they have a high risk tolerance, and prioritize growth overtime.

We will therefore apportion 32% to High-risk stocks and bonds and 24% to real estate. This is because these are risky investments that can bring in high returns overtime.

We will also apportion 17% to Mutual funds and 15% to retirement for diversification purposes.

Cash will be apportioned 3% and low risk stocks and bonds will get 9%. This safety net ensures that the portfolio will have less risk in total but is small enough that they don't interefere with the general goals of the portfolio.

"The ‘luxury’ of having a human rights standard is to be expected in the advanced industrial democracies of the world because these countries are currently experiencing economic stability, flourishing agriculture, and reasonably stable populations. But in the developing world, the situation is more often reversed. Poverty in India, hunger in the Sahel [sub-Saharan West Africa], population pressures in China, or war and terrorism in Somalia all speak of continuing difficulties in trying to secure basic human rights for all people around the world. The so-called North-South dichotomy is a real one—part economic, part ideological, part ecological. In 1992, the [United Nations] Human Development report noted that ‘developing countries enter the global market as unequal partners and leave with unequal rewards. Furthermore, by 1990, the richest 20% of countries had national incomes 60 times greater than those of the poorest 20% of countries. ’ And, on the level of personal income the richest 20% of the world’s people get at least 150 times more than the poorest 20%. It is important to acknowledge these issues while at the same time attempting to move the international system toward a greater global human rights standard. "

The values in the table, which of the algorithms appear to run in reasonable time is algorithms B and algorithms C. Hence option B and C is correct.

What are algorithms?

Algorithms are defined as a finite series of strict instructions, generally used to execute a computation or solve a class of particular issues. For performing calculations and processing data, algorithms are employed as specifications. Based on data storage, sorting, and processing, algorithms are used to solve problems in the best way feasible.

Since the number of steps is equal to 10n 10n for a list of size n n, the number of steps required to sort the list increases linearly as the list's size increases. This is a concrete illustration of polynomial efficiency and shows that the algorithm completes its execution in a reasonable amount of time.

This battle with Mr. Covey was the turning-point in my career as a slave. It rekindled the few expiring embers of freedom, and revived within me a sense of my own manhood. It recalled the departed self-confidence, and inspired me again with a determination to be free. The gratification afforded by the triumph was a full compensation for whatever else might follow, even death itself. He only can understand the deep satisfaction which I experienced, who has himself repelled by force the bloody arm of slavery. I felt as I never felt before. It was a glorious resurrection, from the tomb of slavery, to the heaven of freedom. My long-crushed spirit rose, cowardice departed, bold defiance took its place; and
I now resolved that, however long I might remain a slave in form, the day had passed forever when I could be a slave in fact. I did not hesitate to let it be known of me, that the white man who expected to succeed in whipping, must also succeed in killing me. From this time I was never again what might be called fairly whipped, though I remained a slave four years afterwards. I had several fights, but was never whipped. It was for a long time a matter of surprise to me why Mr. Covey did not immediately have me taken by the constable to the whipping-post, and there regularly whipped for the crime of raising my hand against a white man in defence of myself. And the only explanation I can now think of does not entirely satisfy me; but such as it is, I will give it. Mr. Covey enjoyed the most unbounded reputation for being a first-rate overseer and negro-breaker. It was of considerable importance to him. That reputation was at stake; and had he sent me--a boy about sixteen years old--to the public whipping-post, his reputation would have been lost; so, to save his reputation, he suffered me to go unpunished.

Lake Erie is one of the Great Lakes of the United States. It is also the shallowest and warmest of the five lakes. The drainage basin that

surrounds Lake Erle contains urban areas, as well as agricultural and industrial areas. Because of the amount of nutrients, primarily

phosphates, being transported into Lake Erie from surrounding areas, Lake Erle experienced cultural eutrophication. The surface of the lake developed large blooms of algae, which blocked out the sunlight to the depths of the lake and caused the lake to become anoxic.

In 1972, the Great Lakes Water Quality Agreement was signed between the United States and Canada to reduce phosphate pollution. This was

the beginning of the recovery of Lake Erie. Phosphate-containing detergents have been eliminated from surrounding areas and native species have returned, but the lake is still subjected to pollution, including sewage, which results in beach closures, and invasive species, which drive out native species and change the biome.
