Answer:

BA, ED

Step-by-step explanation:

Yes, it is very important. The idea here is that the decimal point in division problems like these can be moved the same number of places in the same direction in each number without changing the result.

__

1. Without a calculator, this is about 8/5, which you know to be more than 1 and less than 4. The only suitable answer choice is the correct one:

  B  1.645 ft.

__

2. Moving the decimal point 1 place to the left in both numbers, we have ...

  (892×10) ÷ (8×10) = 8290 ÷ 80 . . . . matches A

Moving the decimal point 3 places to the left in both numbers, we have ...

  (892×0.001) ÷ (8×0.001) = 0.892 ÷ 0.008 . . . . matches E

The other choices did something other than move the decimal point the same number of places. (Your calculator can verify this.)

__

3. Moving the decimal point 3 places to the right, we have ...

  (4367×1000) ÷ (0.004×1000) = 4,367,000 ÷ 4 ≈ 1,000,000

_____

Additional comment

For numbers like the ones in problem 3 that differ substantially in magnitude, it can work well to adjust the decimal points in both numbers so the divisor is between 1 and 10. This lets you easily estimate the position of the decimal point in the quotient.

Of course, if you're doing long division by hand, you always adjust the decimal points so the divisor is an integer (possibly with no trailing zeros).

Find the missing side lengths. Leave your answers as radicals in simplest form.

Answers

9514 1404 393

Answer:

x = 18y = 9

Step-by-step explanation:

The ratios of side lengths in a 30°-60°-90° triangle are ...

  1 : √3 : 2

In the same order, the given side lengths are ...

  y : 9√3 : x

Comparing these two sets of ratios, we see that we can make the first equal to the second by multiplying by 9:

  9(1) : 9√3 : 9(2) = y : 9√3 : x

Then y = 9·1 = 9, and x = 9·2 = 18.

The missing side lengths are x = 18, y = 9.

Muhammad, your client, comes to your office. He is from Pakistan and is an avid cricket player. His annual salary and bonus/incentive compensation income, earned as the president of an engineering firm in Virginia, is usually $2 million. He is in the top tax bracket. Muhammad would like to donate $1 million to the Pakistani Cricket Foundation in Islamabad (the foundation is not a U.S. registered charity) to support cricket in his homeland. He assumes he will get an income tax deduction for this.
1. Will Muhammad likely get an income tax deduction for his planned $1 million donation? Why or why not?
2. Should you try to persuade Muhammad to be more patient and make the donation in his will? Why or why not?

Answers

Solution :

It is given that Muhammad annual income is $ 2 millions. He wants to donate $ 1 million to the Pakistani Cricket Foundation to support cricket.

1. Muhammad believes that donating the amount will help him getting a income tax deduction,  but he is not eligible for the tax deduction even if he donates. This is because income tax is deducted only if one donates to a US qualified charitable organization that is a 501(c) 3 type of organizations for any federal tax purposes. The Pakistani Cricket Foundation is not a US qualified charitable organization.

2. Yes, I would persuade Muhammad to be more patient and continue to make donations on his will to some conservation organizations as well. This will help the organization to spend the fund on some useful activities and can also get some tax benefits for the taxa purposes under section 170(h) and 2013(c).

Step-by-step explanation:

The False statement about using the confidence interval method when testing a claim about  μ when  σ is​ unknown is ; The​ P-value method and the classical method are not equivalent to the confidence interval method in that they may yield different results

Mopeds (small motorcycles with an engine capacity below 50 cm^3) are very popular in Europe because of their mobility, ease of operation, and low cost. Suppose the maximum speed of a moped is normally distributed with mean value 46.8 km/h and standard deviation 1.75 km/h. Consider randomly selecting a single such moped.

Required:
a. What is the probability that maximum speed is at most 49 km/h?
b. What is the probability that maximum speed is at least 48 km/h?
c. What is the probability that maximum speed differs from the mean value by at most 2.5 standard deviations?

Answers

Answer:

a) 0.1038 = 10.38% probability that maximum speed is at most 49 km/h

b) 0.2451 = 24.51% probability that maximum speed is at least 48 km/h

c) 0.9876 = 98.76% probability that maximum speed differs from the mean value by at most 2.5 standard deviations

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean value 46.8 km/h and standard deviation 1.75 km/h.

This means that [tex]\mu = 46.8, \sigma = 1.75[/tex]

a. What is the probability that maximum speed is at most 49 km/h?

This is the pvalue of Z when X = 49. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{49 - 46.8}{1.75}[/tex]

[tex]Z = 1.26[/tex]

[tex]Z = 1.26[/tex] has a pvalue of 0.8962

1 - 0.8962 = 0.1038

0.1038 = 10.38% probability that maximum speed is at most 49 km/h.

b. What is the probability that maximum speed is at least 48 km/h?

This is 1 subtracted by the pvalue of Z when X = 48. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{48 - 46.8}{1.75}[/tex]

[tex]Z = 0.69[/tex]

[tex]Z = 0.69[/tex] has a pvalue of 0.7549

1 - 0.7549 = 0.2451

0.2451 = 24.51% probability that maximum speed is at least 48 km/h.

c. What is the probability that maximum speed differs from the mean value by at most 2.5 standard deviations?

Zscores between Z = -2.5 and Z = 2.5, which is the pvalue of Z = 2.5 subtracted by the pvalue of Z = -2.5

Z = 2.5 has a pvalue of 0.9938

Z = -2.5 has a pvalue of 0.0062

0.9938 - 0.0062 = 0.9876

0.9876 = 98.76% probability that maximum speed differs from the mean value by at most 2.5 standard deviations

If you do this, you should be at a negative number that  is ALSO 10 units away from 0, just in a different direction than positive number. both are 10 units from 0.   There always 2 numbers, one 10 units to the right of zero, and one 10 units to the left of zero.

Which statement in the excerpt supports the idea that the author is building a slippery slope argument?adapted from Away with Standardized Testing!Standardized testing is a billion dollar industry. The companies that create these tests charge school districts and institutions millions of dollars to create and administer them. Let us not even forget the millions of dollars they make selling study guide materials for college entrance exams. Some school districts provide waivers so that students do not have to pay to take these exams. However, some students do not have that luxury and must pay for every attempt at the test until they get a desirable score.
