Answer:

2400

Step-by-step explanation:

150 times 4 = 600 times 4 = 2400

Answer:

30 minutes

Step-by-step explanation:

150 sec. x 4 = 600 sec.

600 sec. per mile

600 sec. x 3 = 1800 sec.

1800 sec. / 60 sec. = 30 min.

Answer:

Behavioral Research in Accounting (January 2008) study of Machiavellian traits in accountants

a) Population of interest to the researcher: accountants

b) Sample = 700 accounting alumni

c) The inference made by the researcher = Machiavellian behavior is not required to achieve success in the accounting profession.

d) The non-responses reduce the sample size and this might introduce bias to the inference made to the population.

Step-by-step explanation:

a) Data and Calculations:

Research Question = Is Machiavellian behavior is required to achieve success in the accounting profession?

Population of interest = all accountants

Sample size = 700 accounting alumni of a university

No. of analyzed questionnaires = 198

No. of questionnaires not analyzed due to nonresponse and incomplete answers = 502 (700 - 198)

Percentage of analyzed questionnaires to sample size = 28.3% (198/700 *100)

Percentage of questionnaires not analyzed = 71.7% (100% - 28.3%)

Conclusion reached by the researchers = Machiavellian behavior is not required to achieve success in the accounting profession.

Answer:

0% probability that the mean score for the B group will be at least five points higher than the mean score for the A group

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution, the central limit theorem, and subtraction of normal variables:

Normal probability distribution

When the distribution is normal, we use the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Subtraction of normal variables:

When we subtract two normal variables, the mean is the subtraction of the mean of each variable, while the standard deviation is the square root of the sum of each variance.

Method A:

One student: N(75,30), so [tex]\mu = 75, \sigma = 30[/tex]

Samples of 100 students: [tex]n = 100, s = \frac{30}{\sqrt{100}} = 0.3[/tex]

Method B:

One student: N(74,40), so [tex]\mu = 74, \sigma = 40[/tex]

Samples of 100 students: [tex]n = 100, s = \frac{40}{\sqrt{100}} = 0.4[/tex]

What is the probability that the mean score for the B group will be at least five points higher than the mean score for the A group?

This is the probability that B - A >= 5. So

[tex]\mu_{B-A} = \mu_B - \mu_A = 74 - 75 = -1[/tex]

[tex]s_{B-A} = \sqrt{s_A^{2}+S_B^{2}} = \sqrt{(0.3)^2+(0.4)^2} = 0.5[/tex]

We have to find 1 subtracted by the pvalue of Z when X = 5. So

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

By the Central Limit Theorem

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

[tex]Z = \frac{5 - (-1)}{0.5}[/tex]

[tex]Z = 12[/tex]

[tex]Z = 12[/tex] has a pvalue of 1

1 - 1 = 0, so

0% probability that the mean score for the B group will be at least five points higher than the mean score for the A group

y = (7w - 3m) / 3a

Step-by-step explanation:

w = 3/7ay + 3/7m

multiply each side by 7 to eliminate fractions

7w = 3ay + 3m

3ay = 7w - 3m

y = (7w - 3m) / 3a

Answer:

x = 4

Step-by-step explanation:

Given:

(√x + 2)(√x - 2) = 0

Required:

Find x

SOLUTION:

√x(√x - 2) + 2(√x - 2) = 0 (distributive property)

x - 2√x + 2√x - 4 = 0

x - 4 = 0

x - 4 + 4 = 0 + 4

x = 4

Answer: The answer is,

$5,110

Option (B)

The tax of a single person that earns $33,200 is $5110

The earnings (E) is given as:

[tex]E = \$33,200[/tex]

From the tax table, the equation to calculate the tax of a single person within the income range $28400 to $68,799.99 is:

[tex]Tax =0.25E - 3190[/tex]

So, we have:

[tex]Tax =0.25 \times 33200 - 3190[/tex]

[tex]Tax =8300 - 3190[/tex]

Evaluate the like terms

[tex]Tax =5110[/tex]

Hence, the tax of a single person that earns $33,200 is $5110

Answer:

384 square meters.

Step-by-step explanation:

Given that a cube has a lateral surface area of 64 square meters, to find the total surface area of the cube, the following calculation must be performed, knowing that the formula to calculate the area of a cube is to multiply by 6 (the number of sides of the cube) the area of one of its sides:

A x 6 = X

64 x 6 = X

384 = X

Thus, the area of the cube is 384 square meters.

Answer:

A = 3.57 m²

Step-by-step explanation:

Given that,

The circumference of a circle is 7xm.

The expression for the circumference of a circle is given by :

[tex]C=2\pi r[/tex]

r is the radius of the circle

[tex]r=\dfrac{C}{2\pi}\\\\r=\dfrac{7}{2\times \dfrac{22}{7}}\\\\r=1.11\ m[/tex]

The area of a circle is given by :

[tex]A=\pi r^2\\\\A=3.14\times (1.11)^2\\\\A=3.89\ m^2[/tex]

Out of given option,

A = 3.57 m²

So, the area of the circle is 3.57 m².
