If a single person earns 33,200 what would his taxes be to the nearest dollar

Answers

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

An experiment on the teaching of reading compares two methods, A and B. The response variable is the Degree of Reading Power (DRP) score. The experimenter uses Method A in a class of 100 students and Method B in a comparable class of 100 students. Students are assigned to the two classes at random. Suppose that in the population of all children of this age the DRP score has the N(75, 30) distribution if Method A is used and the N(74, 40) distribution if Method B is used. Let us call the mean DRP score for 100 students in the A group. Let us call the mean DRP score for 100 students in the B group ý.

Required:
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?

Answers

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

a cube has a lateral surface area of 64sq m find the total surface area of the cube

Answers

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.

The circumference of a circle is 7xm.
What is the area of the circle?
A. 3.57x m²
B. 12.257x m2
C. 147xm2
D. 497xm2

Answers

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.

Percents can be expressed as fractions and decimals. A percent means “out of 100,” so we can express 40% as the fraction 40⁄100. We can simplify this fraction to2⁄5 by dividing by the greatest common factor, 20.

We can also express a percent as a decimal. Percents show a part out of a hundred, or hundredths, so you can divide the percent by 100 to find the decimal. 40 divided by 100 equals 40 hundredths, or .4. You can also divide the numerator by the denominator in the simplified fraction, 2⁄5, to find the equivalent decimal.


These values are all equivalent.

75% =

A
75/10

B
2/3

C
3/4

D
3/5

Answers

Answer:

Definitely 3/4!

Step-by-step explanation:

Option A = 7.5

Option B = 66.6%

Option C = 75% (because 25 times 4 is equal to 100%, so 25 times 3 would be 75)

Option D = 6/10 or 60%

The values that are equivalent to 75% are A) 75/100 (0.75) and C) 3/4.

To determine whether these values are equivalent, let's evaluate each expression and compare the results.

A) 75% can be written as a decimal by dividing 75 by 100:

75% = 75/100 = 0.75

B) 2/3 is already in fractional form and cannot be simplified further.

C) 3/4 is also in fractional form and cannot be simplified further.

D) 3/5 is in fractional form and cannot be simplified further.

Now let's compare the decimal equivalents:

0.75 = 75/100

2/3 = 0.666...

3/4 = 0.75

3/5 = 0.6

Comparing the decimal values, we can see that A) 0.75 and C) 0.75 are equivalent, as they both represent 75% in decimal form.

However, B) 2/3 and D) 3/5 do not equal 0.75 and are therefore not equivalent to 75%.

Hence, the values that are equivalent to 75% are A) 75/100 (0.75) and C) 3/4.
