Answer:

$360.12

Step-by-step explanation:

Phan's net pay would be equal to the gross wage he receives minus the deductions:

Gross wage= $487.12

Federal withholding taxes= $49

Social security taxes= $487.12*6.2%= $30.2

Medicare taxes= $487.12*1.45%= $7.06

Health insurance= $28.74

Union dues= $12

Net pay= $487.12-$49-$30.2-$7.06-$28.74-$12

Net pay= $360.12

According to this, Phan's net pay is $360.12.

Phan's net pay is calculated by subtracting the sum of Social Security tax, Medicare tax, federal withholding, health insurance, and union dues from his gross wages. After performing the calculations, Phan's net pay is $360.12.

To calculate Phan's net pay, we first need to determine the amount of each deduction from his gross wages. We will follow these steps:

Now let's do the math:

To calculate the net pay:

Gross wages = $487.12

Total deductions = $127.00

Net pay = Gross wages - Total deductions

Net pay = $487.12 - $127.00 = $360.12

Therefore, Phan's net pay is $360.12.

Step-by-step explanation:

Answer:

The only correct options are A, B and E.

Step-by-step explanation:

He buys [tex]1\frac{1}{2}[/tex] pounds of flour, 12 ounces of coconut, and [tex]1\frac{1}{4}[/tex] pounds of sugar.

We will add these together, but before that, we convert the 12 ounces to pounds, so that all the units are the same:

1 ounce = 0.0625 pounds

12 ounces = 12 * 0.0625 = [tex]\frac{3}{4}[/tex] pounds

He buys  [tex]\frac{3}{4}[/tex] pounds of coconut.

Adding all of them together yields:

[tex]1\frac{1}{2}[/tex] + [tex]\frac{3}{4}[/tex] + [tex]1\frac{1}{4}[/tex] = [tex]3\frac{1}{2}[/tex] pounds

Let us also convert to ounces:

[tex]3\frac{1}{2}[/tex]  / 0.0625 = 56 ounces

Let us also convert 1/2 pound to ounces:

1/2 / 0.0625 = 8 ounces

Hence, the total weight of ingredients that Dwayne bought is [tex]3\frac{1}{2}[/tex] pounds or 56 ounces or 3 pounds 8 ounces

Hence, options A, B and E are correct.

Step-by-step explanation:

The circumference of a regulation basketball hoop with an 18-inch diameter is approximately 56.52 inches.

The question asks for the approximate length around the rim of a regulation basketball hoop, which has an 18-inch diameter. To find the circumference (the length around the rim), we can use the formula:

Circumference =
pi imes diameter

Since the diameter of the rim is 18 inches, we can approximate
pi as 3.14 to calculate the circumference:

Circumference = 3.14 imes 18 inches = 56.52 inches

Thus, the approximate length around the rim of a regulation basketball hoop is about 56.52 inches.

7:9

Step-by-step explanation:

it was 70:70+90 cuz it was 20 moe than kates broom and if u simpifly that it will be 7:9 and sorry if my grammers bad im also a student lol i hope this helps. :)

Given that Kate possessed 70 brooms and Alisa had 20 more brooms than her, Alisa possessed 90 brooms. The ratio of Kate's brooms to Alisa's brooms reduces to 7:9.

The question wants to find the ratio of brooms Kate has to the brooms Alisa has. Firstly, we know Kate has 70 brooms. The question also tells us that Alisa has 20 more brooms than Kate, which means Alisa has 70+20=90 brooms. To establish a ratio, we simply put Kate's brooms to Alisa's brooms which gives us 70:90. However, we always want to reduce the ratio to its simplest form. Both 70 and 90 are divisible by 10, so we divide each side by 10, getting 7:9. The ratio of Kate's brooms to Alisa's brooms is therefore 7:9.

Question:

Evaluate the expression 5^x - 3^x for x=2

Answer:

5^x - 3^x for x=2 is 16

Step-by-step explanation:

Given

5^x - 3^x

x=2

Required

Evaluate

When fazed with question like this all you need is to substitute the value of x (or any other variable{s} used) in the expression.

Recall that x = 2

So, you have to substitute 2 for x in 5^x - 3^x

This gives

[tex]5^2 - 3^2[/tex]

This can be further solved in 2 ways

1. Solve directly

[tex]5^2 - 3^2[/tex]

= [tex]25 - 9[/tex]

= 16

2. Expand using difference of two squares.

Difference of two squares is represented by

[tex]a^2 - b^2 = (a + b) (a - b)[/tex]

By comparison

[tex]5^2 - 3^2[/tex] becomes

[tex]5^2 - 3^2 = (5 + 3) (5 - 3)[/tex]

[tex]5^2 - 3^2 = (8) (2)[/tex]

[tex]5^2 - 3^2 = 8 * 2[/tex]

[tex]5^2 - 3^2 = 16[/tex]

For both ways, we'll arrive at the same answer.

Answer:

a.) [tex]mean=200.3[/tex]

b.) [tex]210[/tex] [tex]cm[/tex]

Step-by-step explanation:

a.) We are given the heights and their frequency. We can make a new set:

198, 199, 199, 199, 200, 200, 201, 201, 201, 201, 201, 202, 202

Now find the mean. The mean is found by adding all the numbers in the set, then dividing the total by the number of terms in the set. Add:

[tex]198+199+199+199+200+200+201+201+201+201+201+202+202=2604[/tex]

Now count the terms. There are 13 terms. Divide the total by the number of terms:

[tex]\frac{2604}{13}= 200.3[/tex]

The mean is 200.3.

b.) Use random values like 200, 198 etc. and add them to the total of the last set, then divide by 14 instead of 13 (because there is a new player). Do this until you get a mean of 201 with the new height:

[tex]2604+210=2814\\\\\frac{2814}{14}= 201[/tex]

For the new mean to be 201 cm, the new player has a height of 210 cm.

Finito.

To estimate the mean height of students at your college or university with 93 percent confidence and a margin of error of 1 inch, you would need to measure approximately 333 male students.

To estimate the mean height of students at your college or university with 93 percent confidence and a margin of error of 1 inch, you need to use the formula for sample size.

The formula for sample size is:

N = ((Z * σ) / E)^2

Where N is the sample size, Z is the Z-score for the desired confidence level, σ is the standard deviation, and E is the margin of error.

In this case, the Z-score for 93 percent confidence is 1.8119 (found using a Z-table). The standard deviation is given as 2.5 inches. Substituting these values into the formula:

N = ((1.8119 * 2.5) / 1)^2

N = 18.2255^2

N ≈ 332.3782

Rounding up to the nearest whole number, you would need to measure approximately 333 male students to estimate the mean height with 93 percent confidence and a margin of error of 1 inch.

When we look at a cylinder, it has be observed that it has 3 parts or 3 shapes to it.

These 3 parts or shapes are referred to as the net of a cylinder.

This 3 parts include

a. A circle at the top

b. A circle at the bottom.

c. A rectangle.

The circle at the bottom gives us the base of the cylinder while the rectangle is curved when forming the cylinder and it is due to this that we have the curved surface area of the cylinder.

It is important to know that there is a relationship between the length of one of the edges of the rectangle and the circumference of the base of the cylinder such that, the length of one of the edges of the rectangle is equal to or equivalent to the circumference of each circular base.

Answer:

42.7 cm sq.

Step-by-step explanation:

small/large = 16 / 122

16/122 = S / 56

S = 56 * (16/122) = 7.34...

however not in the choice

ah ha..

You meant :    12.2 sq. cm :  16 sq. cm  = small / large

so   12.2 / 16 = S / 56 cm

S = 42.7 sq. cm

The surface area of the smaller pyramid is approximately 42.7 cm. Answer: B) 42.7 cm

Area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.

If two pyramids are similar, their corresponding linear dimensions (height, slant height, etc.) are in the same ratio as their corresponding base dimensions.

Let the height of the larger pyramid be h, and let the height of the smaller pyramid be x, h, where x is the scaling factor.

The ratio of their base areas is given by:

(xh)² : h² = 16 : 122

Simplifying this equation, we get:

x²h² = 16/122 * h²

x² = 16/122

x = √(16/122)

Now we know that the linear dimensions of the smaller pyramid are

1/√(122/16) = √(16/122) times that of the larger pyramid.

So, the surface area of the smaller pyramid is:

(16/122) * (56 / (√(16/122))²) = 42.7 cm (rounded to one decimal place)

Therefore, the surface area of the smaller pyramid is approximately 42.7 cm. Answer: B) 42.7 cm

8.6 x 3.14 = 27.00cm (squared) I think. Double check that. But i think ( .00 ) is in the hundredths.

Final answer:

The area of a circle with a radius of 8.6 centimeters is approximately 232.23 square centimeters when calculated using 3.14 for Pi and rounding to the nearest hundredth.

Explanation:

The question is asking to find the area of a circle with a given radius. The formula to calculate the area of a circle is A = πr², where π is a constant (Pi, approximately 3.14) and r is the radius of the circle. To calculate the area with the given radius of 8.6 centimeters:

Insert the radius into the area formula: A = π × (8.6 cm)²

Perform the squaring of the radius: 8.6 cm × 8.6 cm = 73.96 cm²

Multiply the result by Pi (using 3.14 for π): A = 3.14 × 73.96 cm²

Calculate the product: A = 232.23 cm²

Round the result to the nearest hundredth: A ≈ 232.23 cm²

Therefore, the area of the circle is approximately 232.23 square centimeters.

The inequality 3+7<13 represents a situation where the sum of three units and seven units is less than thirteen units. While this does not hold true in a strict mathematical sense, it illustrates the notion of inequality.

The inequality 3+7<13 represents a situation where the sum of three units and seven units is less than thirteen units. The numbers could represent any sorts of units, depending on the real-world situation.

For instance, let's consider an example where each unit represents one apple. According to this inequality, if you have three apples and you add seven more apples, the total number of apples you have would be less than thirteen. As you can see, this does not make sense, because 3+7 equals 10, which is not less than 13. Thus, the inequality 3+7<13 does not hold true in this situation.

This example illustrates that the given inequality does not hold true in a mathematical sense because 3 + 7 equals 10, which is not less than 13. However, in a situation where there is a numerical error or logical inconsistency, this inequality could potentially be used.

Answer:

The solution will experience an instant colour change because thiosulphate which is meant to be used as a clocking or Redox reagent which would have to react with iodine is absent.

Step-by-step explanation:

Thiosulphate is a chemical reagent that is used in chemical reactions such as titrations.

Thiosulphate is used as in the chemical reaction called Iodometry. This is a reaction whereby Thiosulphate is used as reactant and it is titrated against iodine in order to obtain an endpoint.

If Thiosulphate is not added to the test tube, there would be a colour change that occurs instantly because Thiosulphate did not react with iodine.

Without thiosulfate in a chemical reaction, students might observe an unchecked reaction progression, an absent color change, or the non-formation of a precipitate, which could significantly alter the expected outcome of the experiment.

If a group of students forgot to add thiosulfate to one test tube during an experiment, they would likely observe changes in the reaction that the thiosulfate was intended to affect. Depending on the specific experiment, the absence of thiosulfate could result in a faster reaction rate, lack of a particular color change, or the non-formation of a precipitate if thiosulfate is used as a reagent to react with a specific analyte. In general, thiosulfate is often used as a titrant or a reducing agent in various chemical reactions.

For example, in a reaction where thiosulfate is used to quench iodine, forgetting to add it would result in a permanent dark/starch-iodine complex, indicating that the reaction has gone to completion without being stopped by the thiosulfate. In another example, in silver-based photographic processing, thiosulfate is used to remove excess silver halide from developed film or paper; without it, the remaining silver halide would cause the material to be overly dark or discolored.

In the context of the provided information, if thiosulfate were supposed to quench a reaction or produce a specific analytical result, its absence would alter the expected outcome, potentially leading to incorrect conclusions. Observations without thiosulfate could include an unchecked reaction progression or the non-formation of anticipated reaction products.

And rounded up we have that n=1423

c) For this case we can see that if we have a prior estimate the minimum sample size required for the margin of error desired would be less as we can see in part b we reduce the sample size compared to the part a

Step-by-step explanation:

Part a

The critical value for a confidence level of 99% is for this case [tex]z_{\alpha/2} =2.58[/tex]

The margin of error for the proportion interval is given by this formula:  

[tex] ME=z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}[/tex]    (a)  

And on this case we have that [tex]ME =\pm 0.03[/tex] and we are interested in order to find the value of n, if we solve n from equation (a) we got:  

[tex]n=\frac{\hat p (1-\hat p)}{(\frac{ME}{z})^2}[/tex]   (b)  

Since we don't know any estimate for the true proportion we can use [tex]\hat p =0.5[/tex] as a godd estimator. And replacing into equation (b) the values from part a we got:

[tex]n=\frac{0.5(1-0.5)}{(\frac{0.03}{2.58})^2}=1849[/tex]  

And rounded up we have that n=1849

Part b

For this case we have a prior estimate [tex]\hat p =0.26[/tex] and replacing we got:

[tex]n=\frac{0.26(1-0.26)}{(\frac{0.03}{2.58})^2}=1422.99[/tex]  

And rounded up we have that n=1423

Part c

For this case we can see that if we have a prior estimate the minimum sample size required for the margin of error desired would be less as we can see in part b we reduce the sample size compared to the part a
