Answer:

1

Step-by-step explanation:

The given expression is

[tex]\frac{2^{\frac{11}{2} }\times 2^{-7}\times 2^{-5}}{2^3\times 2^{\frac{1}{2} }\times 2^{-10}}[/tex]

Recall and use

[tex]a^m\times a^n=a^{m+n}[/tex]

[tex]\frac{2^{\frac{11}{2} -7-5}}{ 2^{3+\frac{1}{2} -10}}[/tex]

[tex]\frac{2^{-\frac{13}{2}}}{ 2^{-\frac{13}{2}}}[/tex]

Same bases are dividing, so we write one base and subtract the exponent.

[tex]2^{-\frac{13}{2}+\frac{13}{2}}[/tex]

[tex]2^0=1[/tex]

Camden's net pay is 76.75% of his gross pay

Alternative:

100%-15.6%-6.2%-1.45%=76.75%

Final answer:

To calculate Camden's net pay, you subtract federal withholding, Social Security, and Medicare deductions from his gross pay based on provided percentages. By applying these calculations to an example, Camden's net pay from a $2,000 gross salary over two weeks would be $1,535, after deductions totaling $465.

Explanation:

The calculation of Camden's net pay involves subtracting federal withholding, Social Security, and Medicare deductions from his gross pay. Assuming Camden's gross pay is a certain amount, we'll illustrate how to find the net pay. Let's not forget to account for the percentages provided for each deduction category: 15.6% for federal withholding, 6.2% for Social Security, and 1.45% for Medicare.

Calculate Federal Withholding: Gross Pay * 15.6%.

Calculate Social Security Deduction: Gross Pay * 6.2%.

Calculate Medicare Deduction: Gross Pay * 1.45%.

Add all deductions together: Federal Withholding + Social Security + Medicare.

Subtract the total deductions from the Gross Pay to get the Net Pay.

For example, if Camden's gross pay is $2,000 for two weeks, his deductions would be:

Federal Withholding: $2,000 * 15.6% = $312

Social Security: $2,000 * 6.2% = $124

Medicare: $2,000 * 1.45% = $29

Total Deductions: $312 + $124 + $29 = $465

Net Pay: $2,000 - $465 = $1,535

The mean of the students' data set is approximately 8.56 hours of sleep per night, while the mean of the teachers' data set is approximately 6.7 hours of sleep per night. This suggests that, on average, students get more sleep than teachers.

To find the mean of a data set, you need to add up all the values and then divide the sum by the total number of values. Let's start by finding the mean of the students' data set. Summing up the values: 7 + 6 + 8 + 9 + 8 + 9 + 10 + 10 + 10 = 77. Since there are 9 values in the data set, we can calculate the mean by dividing the sum by 9: 77 / 9 = 8.56 (rounded to two decimal places). Therefore, the mean of the students' data set is approximately 8.56 hours of sleep per night.

Next, let's find the mean of the teachers' data set. Summing up the values: 6 + 6 + 4 + 5 + 7 + 8 + 7 + 8 + 8 + 8 = 67. Since there are 10 values in the data set, we can calculate the mean by dividing the sum by 10: 67 / 10 = 6.7 (rounded to one decimal place). Therefore, the mean of the teachers' data set is approximately 6.7 hours of sleep per night.

The means tell us the average amount of sleep that students and teachers get each night. The mean of the students' data set (8.56) suggests that, on average, students get more sleep than the mean of the teachers' data set (6.7). This indicates that, based on this survey, students tend to get more sleep than teachers.

By the way just for the future I'll teach you how to to the problem because it'll be 10x easier for you!

Let's say you have the equation y = -4x - 2

You go 2 down on the y-axis. So place a point on (0, -2)

After that we have -4x which is actually -4/1 which means +1 for the x-axis and -4 on the y-axis!

Which determines our new point to be on (1, -6)

And you just make the lines now or to make it even easier flip (1, -6) to (-1, 6)

That'll make drawing your lines way easier! Good luck ^-^

Answer:

Mean=12.5

Median=13

Step-by-step explanation:

What you do for the mean is you add all the numbers together to get 75.

You will then divide it by 6 because there are 6 numbers to get 12.5 as your answer.

The median all you do is find the middle number. The middle numbers are 12 and 14. You will take 12 and 14 and add them together to get 26.

You will then divide it by 2 to get 13 as your answer.

The Mean of the data is 12.5 and the Median of the data is 13.

Mean is defined as the ratio of the sum of the number of the data sets to the total number of the data. The mean is calculated by adding all the data and dividing it by the number of the data.

The Median is the middle value of the data set when all the data is arranged in ascending order.

Given data is 2, 7, 12, 14, 19, 21. The mean of the data will be calculated as below:-

Mean = ( 2 + 7 + 12 + 14 + 19 + 21 ) / 6

Mean = 75 / 6 = 12.5

The Median will be calculated as below:-

Median = ( 12 + 14 ) / 2

Median = 26 / 2 = 13

Therefore, the Mean of the data is 12.5 and the Median of the data is 13.

Answer: The height of the right rectangular prism is 3.5 meters.

Step-by-step explanation:

To find the height of the right rectangular prism, you need to use the formula of the surface area of a rectangular prism, where [tex]l[/tex] is the lenght, [tex]w[/tex] is the width and the height is [tex]h[/tex]:

[tex]SA=2wh+2lw+2lh[/tex]

Substitute [tex]SA=286[/tex], [tex]l=10[/tex] and [tex]w=8[/tex] into the formula and solve for the height of the right rectangular prism:

[tex]SA=2wh+2lw+2lh\\\\286=2(8)h+2(10)(8)+2(10)h\\\\286=16h+160+20h\\\\286=160+36h\\\\286-160=36h\\\\126=36h\\\\\frac{126}{36}=h\\\\h=3.5\ m[/tex]

Final answer:

Using the surface area formula for a right rectangular prism, the height is calculated to be 3.5 meters after setting up the equation with given surface area, length, and width.

Explanation:

To find the height of a right rectangular prism with a given surface area, length, and width, we can use the surface area formula for a prism: SA = 2lw + 2lh + 2wh, where SA is the surface area, l is the length, w is the width, and h is the height.

Given that the surface area is 286 m2, the length is 10 m, and the width is 8 m, we can set up the equation 286 = 2(10)(8) + 2(10)h + 2(8)h.

Simplify this to 286 = 160 + 20h + 16h, which further simplifies to 286 = 160 + 36h. Subtracting 160 from both sides, we get 126 = 36h. Dividing both sides by 36 gives us h = 3.5 m.

Therefore, the height of the prism is 3.5 meters.

Answer: %53

Step-by-step explanation:

3/20=%15

15+32=%47 for both video games and camp

100-47= %53 left over for college

Answer: .53

Step-by-step explanation: Of Kylies $550, 32% was for a down payment for summer camp. This is calculated with the formula 550 x .32 = $176 down payment.

She used 3/20 for two video games. 3/20 = .15, so the video games cost .15 x $550 = $82.50.

Kylie spent $176 + $82.50 = $258.50.

$550 savings - $258.50 = $291.50 is the amount that she put into her savings account. Expressed as as decimal, it is 291.50/550 = .53, so she put .53 of her babysitting money into her college savings account.

Step-by-step explanation:

Jason starts riding a bike 1 mile from the station.

Shawn starts biking 2 miles from the station.

For Jason to reach Shawn, he needs to go at a higher speed. However we know that they are going at the same constant speed. Then they will never meet.

To prove it we propose the following system of equations. Where x is the hours and y is the distance in miles.

For Jason we have:

[tex]y = 20x + 1[/tex]

For Shawn

[tex]y = 20x + 2[/tex].

We want to know when Jason and Shawn are at the same distance.

Then we write the following eqution and clear x:

[tex]20x + 1 = 20x + 2\\20x -20x + 1 = 2\\1 = 2[/tex]

Equality is not satisfied. Therefore, it has no solution.

Option A

Answer:

12.7

Step-by-step explanation:

The diagonal formula is x*sqrt(2) with x being one side length.

To find the side length divide the perimeter by 4.

That gives us 9.

Then, all you have to do is multiply that by the square root of 2 and then round.

To find the diagonal of a square with a perimeter of 36 inches, calculate the side length as 9 inches and apply the Pythagorean theorem, resulting in a diagonal length of approximately 12.7 inches.

The perimeter of a square is given as 36 inches, so to find the length of one side, we divide the perimeter by 4, since a square has four equal sides. Therefore, each side of the square is 36 inches ÷ 4 = 9 inches. To determine the length of the diagonal, we can apply the Pythagorean theorem in the square. The square's diagonal splits it into two right triangles, each with legs equal to the side of the square. If we denote the length of the diagonal as d and one side as s, the formula d² = s² + s² applies.

With both sides being 9 inches, this becomes d² = 9² + 9², leading to d² = 81 + 81 = 162. Taking the square root to find d, we get d = √162, which is approximately 12.7 inches when rounded to the nearest tenth.

Answer:

D

Step-by-step explanation:

We can use the "vertical line test" to determine whether a given graph represents a function or not.  

If your vertical line intersects the graph in more than one place, the graph does NOT represent a function.  Thus, D does not represent a function, as a line drawn vertically thru this graph intersects the graph multiple times.

Graph A:  Note that if you draw a vertical line thru x = -2, your line will intersect the BLACK dot (-1 3/4, 0) and the EMPTY circle (-1 3/4, 3 1/4).  This is OK; this graph represents a function.
