Answer:

C

Step-by-step explanation:

what is it you don't understand about this ?

the question only asks about a wallpaper border, which is a strip.

so, we don't need any areas, we only need the perimeter of the room.

that means we need to add up all sides.

the little "missing corner" on the top right would hurt us for the area of the room, but not for the perimeter.

just imagine, the room would be a perfect rectangle.

how long would the top side be ?

right, identical to the bottom side : 8 ft.

and how long would the right side be ?

right, identical to the left side : 4 yds.

now, look closely, did we lose (or add anything) of/to the side lengths by the missing corner up there ?

we lost area, but ... we did not lose perimeter distance !

i know, this sounds funny, but it is true. look again.

the short right side plus the long right side are together still the same length as the left side : 4 yds.

and the long top side and the shorter lower top side together are still the same length as the bottom line : 8 ft.

attention trap : the left and right sides are in yds.

1 yd = 3 ft !

so, long story short, the perimeter is as for a normal rectangle

2×length + 2×width = 2×8 + 2×4×3 = 16 + 8×3 = 40 ft

and the border costs $3 per ft, so we get

3×40 = $120

as the total price for the border.

Answer:

x= -9/7

y= -38/7

so it has A. exactly one solution

Step-by-step explanation:

Substitute into one of the equations: 5x+1= -2x-8

Rearrange unknown terms to the left side of the equation: 5x+2x=-8-1

Combine like terms:7x=-8-1

Calculate the sum or difference: 8x=-9

Divide both sides of the equation by the coefficient of variable: x=-9/7

Substitute into one of the equations:y=-2×(-9/7)-8

Write as a single fraction:y=2×9/7-8

Calculate the product or quotient:y=18/7 -8

Convert the expression into a fraction: y=18/7 -8/1

Expand the fraction to get the least common demominator:y=18/7-8x7/1x7

Calculate the product or quotient: y=18/7-56/7

Write the numerators over common denominator:y=18-56/7

Calculate the sum or difference: y=-38/7

Rewrite the fraction: y= -38/7

The solution of the system is:

x= -9/7

y= -38/7

Answer:

Jayce should not use either option. Option 1 is likely to be based so that paperbacks are overrepresented, while Option 2 is likely to be biased so that e-books are overrepresented.

Step-by-step explanation:

Given:

Jayce volunteers for the local library. The librarian wants to find out whether the patrons prefer paperback books or e-books. Jayce cannot decide which method to use for polling the patrons.

Option 1: Poll every fifth patron who enters the library on Paperback Lovers Day.

Option 2: Poll every third patron who enters the library on Technology Appreciation Day.

Since, Option 1: Poll every fifth patron who enters the library on Paperback Lovers Day. It biased because since it paperback lovers day thus, it would be likely that most people like the paperback which make it biased.

Since, Option 2: Poll every third patron who enters the library on Technology Appreciation Day. It biased because since it technology appreciation day thus, it would be likely that most people don't care about these stuff since people coming in are for technology appreciation.

Therefore, the answer is:

Jayce should not use either option. Option 1 is likely to be based so that paperbacks are overrepresented, while Option 2 is likely to be biased so that e-books are overrepresented.

Answer: she needs 3281/12 sq inches

Step-by-step explanation:

12 * 12.25 = 147 sq inches

Answer:

A bag contains 9 pennies, 8 nickels and 5 dimes: 22 coins total

5/30 = 1/6

22 + 8 = 30

 8 quarters would give the needed 30 coin total

P(dime) = 5/30 = 1/6

Step-by-step explanation:

No quarters should be added to the bag so the probability of drawing a dime is 1/6

Let x be the number of quarters to be added to the bag.

The probability of drawing a dime can be found by dividing the number of dimes in the bag by the total number of coins in the bag after adding x quarters.

The total number of coins in the bag before adding any quarters is:

9 pennies + 8 nickels + 5 dimes = 22 coins

After adding x quarters, the total number of coins in the bag becomes:

9 pennies + 8 nickels + 5 dimes + x quarters = 22 + x coins

The probability of drawing a dime is given as 1/6.

So, we can set up the equation:

5 / (22 + x) = 1/6

30 = 5(22 + x)

30 = 110 + 5x

-80 = 5x

x = -16

Since x represents the number of quarters to be added, it cannot be negative. Therefore, it is not possible to add any quarters to the bag so that the probability of drawing a dime is 1/6.

Hence, the answer is zero quarters.

Answer: Doctor A: 751.6   Doctor B: 755.2   Doctor B has an average of 3.6 more patients wearing corrective lenses than Doctor A.

Step-by-step explanation:

To find the mean for corrective lenses, add up all of the numbers and divide by the number of data points.

Doctor A's mean:

Add up the data points: 745+726+769+765+756+742+747+748+770+738 = 7516. Count the number of data points to get 10. Divide 7516 by 10. 7516/10 = 751.6.

Doctor B's mean:

Add up the data points: 763+736+735+759+748+756+765+761+768+761 = 7552. Divide by 10. 7552/10 = 755.2

Difference:

755.2-751.6 = 3.6

Doctor A: 751.6 Doctor B: 755.2 Doctor B has an average of 3.6 more patients wearing corrective lenses than Doctor A.

Answer:

[tex]\dfrac{4}{7}x^7-\dfrac{1}{2}x^4+\dfrac{7}{2}x^2-4x+\text{C}[/tex]

Step-by-step explanation:

Integration is the "opposite" of differentiation.

Fundamental Theorem of Calculus

[tex]\displaystyle \int \text{f}(x)\:\text{d}x=\text{F}(x)+\text{C} \iff \text{f}(x)=\dfrac{\text{d}}{\text{d}x}(\text{F}(x))[/tex]

If differentiating takes you from one function to another, then integrating the second function will take you back to the first with a constant of integration (C).

[tex]\boxed{\begin{minipage}{5 cm}\underline{Integrating a constant}\\\\$\displaystyle \int n\:\text{d}x=nx+\text{C}$\\(where $n$ is any constant value)\end{minipage}}[/tex]

Just add an x to the constant.

[tex]\boxed{\begin{minipage}{4 cm}\underline{Integrating $x^n$}\\\\$\displaystyle \int x^n\:\text{d}x=\dfrac{x^{n+1}}{n+1}+\text{C}$\end{minipage}}[/tex]

Increase the power by 1, then divide by the new power.

[tex]\boxed{\begin{minipage}{5 cm}\underline{Terms multiplied by constants}\\\\$\displaystyle \int ax^n\:\text{d}x=a \int x^n \:\text{d}x$\end{minipage}}[/tex]

If the terms are multiplied by constants, take them outside the integral.

Given indefinite integral:

[tex]\displaystyle \int (4x^6-2x^3+7x-4)\:dx[/tex]

Integrate each term separately and take the constants outside the integrals:

[tex]\implies \displaystyle 4 \int x^6\:\text{d}x - 2 \int x^3 \:\text{d}x + 7 \int x \:\text{d}x - \int 4 \:\text{d}x[/tex]

Integrate, using the rules given above:

[tex]\implies 4 \cdot \dfrac{x^7}{7}-2 \cdot \dfrac{x^4}{4}+7 \cdot \dfrac{x^2}{2}-4x+\text{C}[/tex]

Simplify:

[tex]\implies \dfrac{4}{7}x^7-\dfrac{1}{2}x^4+\dfrac{7}{2}x^2-4x+\text{C}[/tex]

Length of the coffee table will be 12.25 inch

What is Area of square?

The area of square is length time width.

Given that;

Area of square coffee table = 150 square inches.

Now,

Area of square = (side)²

Substitute the value of area of square,

Side² = 150

Take square root both sides,

Side = √150

Side = 12.247

After rounding it,

Side = 12.25

Thus, Length of the coffee table will be 12.25 inch.

Answer:

Surface Area: 34

Volume: 10[tex]u^{2}[/tex]

Step-by-step explanation:

Volume = l*w*h

We need to divide the shapes up.

First Shape: 3 length * 1 width * 2 height

Second Shape: 2 length * 1 width * 2 height

6+4=10

Surface Area: 2(lw+wh+hl)

Lets divide the shape into two parts again and plug in the number into the formula.

2(3+2+6) = 2(11) = 22

However, for this, two units are inside to shape because we split it up. We can remove these 2 units.

22-2=20

Now we move to the next shape.

(Keep in mind, you can always just count surface area.)

2(2+2+4) = 2(8) = 16

However, again, two units are inside the shape because this is not just a simple figure.

16-2=14
