This scatterplot and regression line below show the relationship between the average rent for a 1-bedroom apartment in New York and the number of years after the year 2000. The fitted line has a y-intercept of 800. What is the best interpretation of this y-intercept?

Answers

Answer: That the average price of a 1-bedroom apartment in New York in the year 2000 was around $800.

Step-by-step explanation:

In this case, x represents the number of years after the year 2000.

Then we can think that x = 0, represents the year 2000 itself.

Now, remember that the y-intercept is the value of y when we have x = 0.

Then the y-intercept gives information about the average price of a 1-bedroom apartment in the year 2000.

The information that we can conclude with this is that the average price of a 1-bedroom apartment in New York in the year 2000 was around $800.

The differences between a physical change and a chemical change are as follows :

Physical change is a temporary and usually reversible change in which no new substances are formed whereas Chemical change is a permanent and it is usually an irreversible change in which new substances with different properties are formed. In physical change, the chemical composition of the substance remains the same but only the physical properties like state , colour , speed , motion , shape , size etc are changed whereas In chemical change , the physical properties , the chemical properties and the chemical composition of the substances are changed.Physical change is a reversible change as it occurs in forward as well as backward directions whereas chemical change is an irreversible change as it cannot be reversed back from products to reactants.Some of the examples of physical change are glowing of an electric bulb , magnetising an iron nail , preparing a solution , changing of ice into water and water vapour etc. Some of the examples of chemical change are changing milk into curd , rusting of iron , burning magnesium ribbon , decaying grasses , cooking rice etc.

Find the measure of angle b

Answers

Answer:

130°

Step-by-step explanation:

a straight line is 180°

so you have

180°-50°= 130°

explanation:

b and 50 are supplementary angles (they add up to 180), so create an equation by adding them up to equal 180:

b + 50 = 180

we want the x by itself, so subtract both sides by 50 to get:

b = 130°

Cape Corp. Will pay a dividend of $4.40 next year. The company has stated that it will maintain a constant growth rate of 5 percent a year forever. a. If you want a return of 17 percent, how much will you pay for the stock? (Do not round intermediate calculations and round your answer to 2 decimal places, e.G., 32.16.) b. If you want a return of 10 percent, how much will you pay for the stock? (Do not round intermediate calculations and round your answer to 2 decimal places, e.G., 32.16.)

Answers

Answer:

Step-by-step explanation:

a. If you want a return of 17 percent, how much will you pay for the stock?

The price of the stock can be calculated as:

= dividend next year/(required return - growth rate)

= 4.4/(17% - 5%)

= 4.4/12%

= 4.4/0.12

= 36.67

b. If you want a return of 10 percent, how much will you pay for the stock?

At 10%

= 4.4/(10% - 5%)

= 4.4/5%

= 4.4/0.05

= 88

Una caja contiene 448 mascarillas, las cuales se deben acomodar en 3 cajas más pequeñas. En la primera se deben poner ; 1/8, del total, en la segunda 3/8 y en la tercera 4/8 ¿Cuántas mascarillas van en cada caja y cuántas quedan en la caja original?

Answers

Step-by-step explanation:

Si una caja contiene 448 cajas y debe acomodarse en tres cajas más pequeñas, si la primera contiene 1/8 del total, entonces el número de cajas en la primera será:

[tex]= \frac{1}{8}\times 448\\ = \frac{448}{8}\\ = \frac{8\times56}{8}\\ = 56[/tex]

Por lo tanto, la primera caja contiene 56 cajas más pequeñas.

Si el segundo contiene 3/8 del total, entonces el número de casillas en el segundo será:

[tex]= \frac{3}{8}\times 448\\ = \frac{3\times448}{8}\\ = \frac{8\times 3 \times 56}{8}\\ = 3 \times56\\= 168[/tex]

Por lo tanto, la segunda caja contiene 168 cajas más pequeñas.

Si el tercero contiene 4/8 del total, entonces el número de casillas en el tercero será:

[tex]= \frac{4}{8}\times 448\\ = \frac{1}{2} \times 448\\ = 224[/tex]

Por lo tanto, la tercera caja contiene 224 cajas más pequeñas.

La cantidad que quede en la casilla original se expresará como

= 448- (56 + 168 + 224)

= 448-448

= 0

Por lo tanto, no quedó ninguno en la caja original.

2. x-2y =2

4. y+3 = 1/2 (x+4)

5. y-2= 1/2 (x-2)

Answers

Answer:

2, 3 and 4 represent the graph in the pic

Step-by-step explanation:

When you look at the graph, you can immediately tell the gradient and the y-intercept. The gradient is 1/2 and the y-intercept is -1

Hence the graph in the picture follows the formula: y = 1/2x - 1

When you expand/rearrange the options (1-5) into the slope form you would be able to see which of these options matches with the formula of the line.

1. y= 2x-1: Isn't the same as the equation of the line in the pic

2. Rearrange:

-2y = -x + 2        (divide both sides by 2)

y = x/2 - 1          (x/2 = 1/2x, its the same thing)

3. y= 1/2x - 1       (this is the formula of the line)

4. Expand right-hand-side:

y + 3 = 1/2x + 2    (rearrange)

y = 1/2x - 1            (this is the formula of the line)

5. Expand right-hand-side

y - 2 = 1/2x - 1      (rearrange)

y = 1/2x + 1          (is not the formula of the equation)

Ara is lining the bottom and lateral faces of a drawer with liner paper. The dimensions of the inside of the drawer are 1 yard, 29 inches, and 9 inches. What is the total area in square inches being covered? The total area being covered is square inches.

Answers

Answer:

The total area being covered is 3,528 square inches

Step-by-step explanation:

Mathematically, we can deduce the shape of the drawer using the dimensions.

With the dimensions given, we can infer that the drawer is shaped like a match box which thus is in the shape of a cuboid.

We can then proceed to find the area of the cuboid.

Mathematically, the area of a cuboid can be calculated as;

2(lb + lh + bh)

Kindly note we need to have a uniform unit before we proceed to calculate the area.

Mathematically, 1 yard is 36 inches

So the sides of the drawer measures 36 inches by 29 inches by 9 inches

Thus, the area is thus;

2( 29(9) + 36(29) + 9(36))

= 2(261 + 1044 + 324)

= 2(1629)

So the area of the drawer is 3,528 square inches

If Courtney paid a total of $27.93 to download songs, which includes $2.06 for tax, how many songs did she download at a cost of $1.99 per song?

Answers

Answer:

13 songs.

Step-by-step explanation:

$27.93 - $2.06 = $25.87 in order to get the price of the songs before the tax.

Since each song cost $1.99, $25.87 divided by $1.99 is equal to 13

Answer:

13 songs

Step-by-step explanation:

The total cost of the songs is $27.93, including the tax. The tax cost should be removed from the total cost to find how many songs Courtney downloaded because she didn't pay $2.06 for the songs.

[tex]27.93 - 2.06 = 25.87[/tex]

The cost of all the songs is $25.87. Each one costs $1.99 so, to find how many songs she bought, the cost of each song should be divided from the total cost.

[tex]25.87 \div 1.99 = 13[/tex]

Answers

First you add 5x+7x=12x
Next add 3+4=7
So it’s 12x+7

Answer:

12x +7

Step-by-step explanation:

First determine what numbers are coefficients. Because 3 and 4 don't have a variable in them, we know they are coefficients. You can then add them together to get 7. After that, we see that 5x and 7x both share the variable x. Because they share the same variable you can add them together to get 12x. Because 12x and 7 don't have the same variable you cannot add them together. This means that 12x + 7 is your final answer.

2x² + 2x + 1 = 221
Subtract 221 from both sides to make quadratic form:
2x² + 2x - 220 = 0

Answers

Answer:

slope = [tex]\frac{4}{3}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 5, - 8) and (x₂, y₂ ) = (7, 8) ← 2 points on the green line

m = [tex]\frac{8+8}{7+5}[/tex] = [tex]\frac{16}{12}[/tex] = [tex]\frac{4}{3}[/tex]

Repeat with (x₁, y₁ ) = (0, - 6) and (x₂, y₂ ) = (3, - 2) ← 2 points on the blue line

m = [tex]\frac{-2+6}{3-0}[/tex] = [tex]\frac{4}{3}[/tex]

Since the slopes of both lines are equal, then the lines are parallel
