An urn contains n balls, one of which one is special. If k of these balls are withdrawn one at a time, with each selection being equally likely to be any of the balls that remain at the time, what is the probability that the special ball is chosen

Answers

Using it's concept, it is found that the probability that the special ball is chosen is given by:

[tex]p = \frac{1}{C_{n,k}}[/tex]

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

The total number of outcomes is given by the combination of k balls from the set of n balls, given by:

[tex]C_{n,k} = \frac{n!}{k!(n - k)!}[/tex]

One ball is special, hence the probability the special ball is chosen is given by:

You are the head seamstress at a boutique that specializes in making prom dresses. You are supervising the construction of a new style of dress that will take 180 hours of work to complete. Twenty percent of this time is for beading. Thirty-five percent of this time is for adding ruffles. The remaining time is divided equally between embroidery and sewing. When pricing this style, hourly labor and material costs are $40 for beading, $35 for ruffles, $20 for embroidery, and $18 for sewing. The dress is then sold in the showroom for 25% more than the cost of labor and materials. How much will this dress sell for in the boutique?

Answers

The amount at which the dress will sell for in the boutique is $6716.25.

What is the sellig price of the dress?

The total cost of beading = 180 x 25% x $40 = $1800

The total cost of ruffles = 35% x 180 x $35 = 2205

Time left for making embroidery and sewing = (100% - 35% - 25%)/2 = 20%

The total cost of embroidery = 20% x 180 x $20 = $720

The total cost of sewing = 20% x 180 x $18 = $648

Total cost = 5373

Selling price = 1.25 x 5373 = $6716.25

Answers

Answer:

86.28 degrees

Step-by-step explanation:

Angle between vectors is

[tex] \cos(x) = \frac{cross \: product}{magnitudes \: multiplied} [/tex]

The cross product is

[tex]4 + 0 - 3 = 1[/tex]

The magnitudes of first vector is

[tex] \sqrt{1 {}^{2} + 2 {}^{2} + 3 {}^{2} } = \sqrt{14} [/tex]

The second vector magnitude is

[tex] \sqrt{17} [/tex]

So the magnitudes multiplied is

[tex] \sqrt{14} \times \sqrt{17} = \sqrt{238} [/tex]

So our equation will be

[tex] \cos(x) = \frac{1}{ \sqrt{238} } [/tex]

[tex]x = \cos {}^{ - 1} ( \frac{1}{ \sqrt{238} } ) [/tex]

X is about 86.28 degrees

If a hypothesis is not rejected at the 5% level of significance, it a. will always be rejected at the 1% level b. will also not be rejected at the 1% level c. will sometimes be rejected at the 0.1% level d. will sometimes be rejected at the 1% level

Answers

Considering the p-value of the test, the correct option is:

b. will also not be rejected at the 1% level.

How do we reach the decision to reject or not reject the null hypothesis?

It depends on the p-value of the test, as follows:

If the p-value is greater than the significance level, we do not reject the null hypothesis.If it is less than the significance level, we reject the null hypothesis.

In this problem, the hypothesis is not rejected at the 5% level of significance, hence the p-value is greater than 0.05, which means that it will not be rejected at any level below 5% and option b is correct.

New York City has a population of approximately 8.8 million people with a population density of approximately 29,300 people per square mi
What is the approximate area of New York City to the nearest square mile?
The area of New York City is approximately
square miles.

Answers

Answer:

300 square miles (nearest square mile).

Step-by-step explanation:

Population Density formula

[tex]\sf Population\;Density=\dfrac{Number\;of\;People}{Land\;Area}[/tex]

Given values:

Total population = 8,800,000 people.Population density = 29,300 per square mile.

Substitute the given values into the formula and solve for land area:

[tex]\implies \sf 29300=\dfrac{8800000}{Land\;Area}[/tex]

[tex]\implies \sf Land\;Area=\dfrac{8800000}{29300}[/tex]

[tex]\implies \sf Land\:Area=300.3412969...square\;miles[/tex]

Therefore, the approximate area of New York City is 300 square miles (nearest square mile).

We know, however, that bonds typically have a lower rate of return than stocks.Why would people be advised to invest in assets that give lower average rates of return?a. This is bad advice. People should always invest in whichever assets have the highest average rate of return.b. Although stocks have a higher rate of return in the long run, they are much more volatile, or riskier, in the short run. Therefore, there is a higher probability that the value of the stocks will be less than the original value of the investment for people who might need to withdraw the investment in the short run.c. Since bondholders get paid before stockholders in the event of bankruptcy of a firm, the average "real" rate of return on stocks and bonds will be the same, with bonds being less risky.d. Although stocks have higher average rates of return in the long run, bonds have higher average rates of return in the short run. Therefore, bonds are likely to be more profitable for people who might need to get their investment back in the short run.
