The percent increase from 2013 to 2014 is given as follows:

39%.

The percent increase from 2013 to 2014 is obtained applying the proportions in the context of the problem.

The amounts were of 631 in 2013 and 877 in 2014, hence the percentage of 2014's amount relative to 2013's amount is given as follows:

877/631 x 100% = 139%.

The initial amount has a percentage of 100%, hence the percent increase from 2013 to 2014 is given as follows:

Let's call the cost of each video game "x". We can set up two equations based on the information given:

4x + 2(0.01) = 20.92 (the 0.01 represents the commission fee for each phone)

4x = 20.92 - 0.02

4x = 20.90

x = 5.225

So each video game costs $5.225.

We can double-check our answer using the information about the friend's sales:

4(5.225) + 3(0.01) = 23.44

20.90 + 0.03 = 23.44

23.44 = 23.44

So our answer is correct.

The recipe will need 21 cups of sauce and three and a half teaspoons of oregano for 7 servings. The correct option is C.

The sauce to oregano ratio for five servings is equal to 15 cups and 2.5 teaspoons, respectively. For a single portion of the recipe, this computes to 3 cups and 0.5 teaspoons.

It should be noted that to attain the correct amount needed for seven servings, simply multiply each part of the ratio by seven. Consequently, you should use 21 cups of sauce and three and one-half teaspoons of oregano.

The two inequalities that the graph represents are:

y ≤ ²/₃x - 4

An inequality can be represented graphically as a region on one side of a line. Inequalities that use < or > symbols are plotted with a dashed line to show that the line is not included in the region. Inequalities that use ≤ or ≥ symbols are plotted with a solid line to show that the line is included in the region.

The formula for the equation of a line in slope intercept form is:

y = mx + c

where:

m is slope

c is y-intercept

The first inequality is the one with the dashed line and a y-intercept of 4 and so since shaded below line, we will use the symbol <.

The slope from two coordinates on the line (0, 4) and (4, 0) is:

(0 - 4)/(4 - 0) = -1

Thus, inequality is:

y < -x + 4

The first inequality is the one with the solid line and a y-intercept of -4 and so since shaded below line, we will use the symbol ≤.

The real exchange rate is 0.75.

It is not possible to make a profit by buying apples in one country and selling them in another.

We have,

To find the real exchange rate, we need to compare the price of apples in the two countries in terms of their respective currencies.

In the U.S., a bushel of apples costs $15.00.

In Japan, the same apples cost 1,600 yen.

Using the exchange rate of 80 yen per dollar, we can convert the cost in yen to dollars:

1,600 yen / 80 yen per dollar

= $20.00

So, the price of a bushel of apples in Japan is equivalent to $20.00 in the U.S.

The real exchange rate is the ratio of the prices of the same goods in two different countries, taking into account the exchange rate.

In this case, the real exchange rate is:

Real exchange rate = Price in U.S. / Price in Japan

= $15.00 / $20.00

= 0.75

This means that it takes 0.75 U.S. dollars to buy the same goods in Japan which would cost 1 Japanese yen.

To determine if there is an arbitrage opportunity, we need to compare the real exchange rate with the actual exchange rate.

If the real exchange rate is greater than the actual exchange rate, there is an arbitrage opportunity for someone to buy the good in one country and sell it in another country for a profit.

However, if the real exchange rate is less than the actual exchange rate, there is no arbitrage opportunity.

In this case,

The real exchange rate is 0.75, while the actual exchange rate is 80 yen per dollar, or 0.0125.

Since the real exchange rate is less than the actual exchange rate, there is no arbitrage opportunity.

Therefore,

The real exchange rate is 0.75.

The total time taken to walk the museum is t = 3/4 of an hour

Given data ,

Let the time spent at the first 3 exhibits = 3/4 + 3/4 + 3/4 = 9/4 hours

Let the time spent at the museum after the first 3 exhibits = 1 1/2 = 3/2 hours

Total time spent at the museum = 9/4 + 3/2 = (9/4 + 6/4) = 15/4 hours

Since the museum closes after you spend a total of 4 1/2 hours at the museum, we can subtract the total time spent at the museum from the closing time to find the time it took you to walk to the museum:

Closing time - Total time spent at the museum = 4 1/2 - 15/4

On simplifying the equation , we get

A = 9/2 - 15/4

On subtracting the fractions , we get

9/2 - 15/4 = (18/4) - (15/4) = 3/4

Since John cannot buy a fraction of a can, he needs to round up to the nearest whole number. So, John needs at least 5 cans of paint to cover the entire wall as per the height and length.

To calculate the area of the wall, we need to multiply the height and the length of the wall.

From the diagram, we can see that the height of the wall is 2 meters and the length is 5 meters.

So the total area of the wall is:

Area = height x length

Area = 2 meters x 5 meters

Area = 10 square meters

To convert this to square feet, we can use the conversion factor:

1 square meter = 10.764 square feet

So:

Area = 10 square meters x 10.764 square feet/square meter

Area = 107.64 square feet

Since 1 can of paint covers 24 square feet, John needs:

Number of cans = Area ÷ Coverage per can

Number of cans = 107.64 square feet ÷ 24 square feet/can

Number of cans = 4.485 cans

Thus, John needs at least 5 cans of paint to cover the entire wall.

Step-by-step explanation:We can solve this quadratic equation in sin(θ) by using the substitution u = sin(θ):

-6u^2 - 5u + 3 = 0

Now we can use the quadratic formula to solve for u:

u = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = -6, b = -5, and c = 3. Substituting these values, we get:

u = (5 ± sqrt(5^2 - 4(-6)(3))) / 2(-6)

u = (5 ± sqrt(109)) / (-12)

Therefore, either:

sin(θ) = (5 + sqrt(109)) / (-12)

or:

sin(θ) = (5 - sqrt(109)) / (-12)

For example, let's say we have a collection of sets I that includes sets A, B, C, D, E, and F. If we have two sets [tex]D_{i}[/tex] and [tex]D_{j}[/tex], where [tex]D_{i}[/tex] is the set of all even numbers, and [tex]D_{j}[/tex] is the set of all positive integers less than or equal to 10, then we can say that there exists a set [tex]D_{k}[/tex] in I that contains both [tex]D_{i}[/tex]and [tex]D_{j}[/tex] as subsets.

In this case, the set [tex]D_{k}[/tex] could be the set of all even positive integers less than or equal to 10. This set contains all the elements of [tex]D_{i}[/tex] and [tex]D_{j}[/tex], making them both subsets of [tex]D_{k}[/tex]. The statement "there is some k belongs I such that [tex]D_{i}[/tex] is a subset of [tex]D_{k}[/tex] and [tex]D_{j}[/tex] is a subset of [tex]D_{k}[/tex]" is a way to express this relationship between the sets.

Step-by-step explanation:The six sample minimums are 15, 15, 15, 18, 18, and 20.

To find the mean of all six sample minimums, we add them up and divide by 6:

(15 + 15 + 15 + 18 + 18 + 20) / 6 = 16.1667

So the mean of all six sample minimums is $16,166.67.

The population minimum is the smallest cost among the four cars, which is $15,000.

The sample minimum is a biased estimator of the population minimum. Since the samples are of size 2, the probability of obtaining the population minimum as the sample minimum is only 1/3 (when the minimum of the two cars selected is the population minimum). Therefore, the sample minimum tends to underestimate the population minimum.

Answer:

To calculate the average annual percentage gain, we need to use the formula:

Average annual percentage gain = ((Ending value / Beginning value)^(1/n) - 1) x 100%

where:

- Ending value = the value of the investment at the end of the period

- Beginning value = the value of the investment at the beginning of the period

- n = the number of years

In this case, the beginning value of the stocks is not given, so we cannot calculate the exact average annual percentage gain. We only know the profit and the ending value. However, we can make an estimate assuming that the profit is equal to the gain, i.e., there were no transaction costs or other fees.

If the profit was $3,250 and the ending value was $10,500, then the beginning value was:

Beginning value = Ending value - Profit

Beginning value = $10,500 - $3,250

Beginning value = $7,250

The number of years is given as 4.

Using the formula above, we can estimate the average annual percentage gain as:

((10,500 / 7,250)^(1/4) - 1) x 100%

= (1.1267^(0.25) - 1) x 100%

= (1.0266 - 1) x 100%

= 0.0266 x 100%

= 2.66%

Therefore, the estimated average annual percentage gain is 2.66%.
