The currency used in Japan is called the yen, and the currency used in the United States is called the dollar. When you want to know how much a certain amount of yen is worth in dollars, you need to know the exchange rate between the two currencies.

As of my knowledge cutoff, the exchange rate between the yen and the dollar can fluctuate. But to give you a rough idea, as of 2021, the exchange rate was around 1 dollar equals to 108 yen. To convert 200,000 yen to dollars, you would divide 200,000 by 108. So 200,000 yen is roughly equal to about 1,851 dollars.

It's important to keep in mind that exchange rates can change over time, so the amount in dollars may be different at different times. Additionally, the rates may vary depending on the method of exchange and the institution you are using to exchange the currencies.

Step-by-step explanation:

The cost when no sugar is transported is 3250, so that is the "y-intercept". (There is no "y". The vertical axis is labeled "c", so that  is the c-intercept.)

The cost per ton is 125, so that is the slope or "rate of change". Each increase of 1 unit in the value of "s" will result in an increase of 125 in the value of "c". The grid lines for "c" are 500 apart, so 1 vertical grid space will correspond to 500/125 = 4 horizontal grid spaces.

The graph starts at the left side halfway between 3000 and 3500. It goes up 1 grid square for each 4 grid squares to the right.

a) The value of t0 is 1.7709.

b) The value of t0 is -2.8609.

c) The value of t0 is 2.2622.

d) The value of t0 is -3.4175.

To find the values of t0 for each statement, we can use the table of critical values of t. The table provides the critical values of t for different degrees of freedom (df) and desired levels of significance (alpha).

a) For the statement P(t - t0 < t < t0) = 0.095, where df = 13, we need to find the critical value of t for a two-tailed test with a significance level of alpha = 0.05. Looking at the table, the closest value to 0.095 is 0.100, which corresponds to a critical value of t0 = 1.7709.

b) For the statement P(t <= t0) = 0.01, where df = 19, we need to find the critical value of t for a one-tailed test with a significance level of alpha = 0.01. In the table, the closest value to 0.01 is 0.005, which corresponds to a critical value of t0 = -2.8609.

c) For the statement P(t <= -t0 or t >= t0) = 0.010, where df = 9, we need to find the critical value of t for a two-tailed test with a significance level of alpha = 0.005 (split equally between both tails). The closest value to 0.010 is 0.025, which corresponds to a critical value of t0 = 2.2622.

d) For the statement P(t <= -t0 or t >= t0) = 0.001, where df = 14, we need to find the critical value of t for a two-tailed test with a significance level of alpha = 0.001 (split equally between both tails). The closest value to 0.001 is 0.001, which corresponds to a critical value of t0 = -3.4175.

one leg of a right triangle is 6 inches longer than the other leg, and the hypotenuse is 30 inches. Thus,

The lengths of the legs of the triangle are 18 inches,24 inches and  30 inches.

Three vertices make up a triangle, a three-sided polygon. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.

Given that,

one leg of a right triangle is 6 inches longer than the other leg.

hypotenuse is 30 inches.

Let assume, the other leg be x

It is given that, one leg of a right triangle is 6 inches longer than the other leg. So, One leg = x + 6

Since it is a right angled triangle,

h² = p² + b²

Where, h = hypotenuse

p = perpendicular

B = Base

So, (30)² = (x+6)² + x²

or, x = -24, 18

As, the length of side cannot be negative so x becomes 18.

Thus, x + 6 = 18 + 6 = 24 inches

Hypotenuse = 30 inches

Hence, the lengths of the legs of the triangle are 18 inches, 24 inches and  30 inches.

Answer:

x = 11

z = 86

Step-by-step explanation:

8x + 6 and 10x-16 are vertical angles

Vertical angles are pairs of angles that are opposite each other and have the same vertex, or point of intersection. They are formed when two lines intersect at a point, and are always congruent, or of equal measure.

To solve this equation, we need to isolate the variable x on one side of the equation. To do this, we can start by subtracting 6 from both sides of the equation:

8x + 6 - 6 = 10x - 16 - 6

8x = 10x - 22

Now we can subtract 8x from both sides of the equation:

8x - 8x = 10x - 22 - 8x

0 = 2x - 22

To solve for x, we can add 22 to both sides of the equation:

0 + 22 = 2x - 22 + 22

22 = 2x

Finally, we can divide both sides of the equation by 2 to find the value of x: 22 / 2 = 2x / 2

x = 11

Therefore, the solution to the equation is x = 11.

Now that we have x, z is a supplementary angle to 8x + 6 (or you could do 10x - 16)

Supplementary angles are pairs of angles that add up to 180 degrees. They are formed when two lines intersect at a point, and the angles formed at the intersection are supplementary.

First plug in x, 8x + 6 = 8(11) + 6 = 88 + 6 = 94

180 - 94 = z

z = 86

The average number of days appointments are booked in advance has increased since 2017.

What is the average?

This is the arithmetic mean and is calculated by adding a group of numbers and then dividing by the count of those numbers. For example, the average of 2, 3, 3, 5, 7, and 10 is 30 divided by 6, which is 5.

a.

Null hypothesis: H0: μ ≤ 24 (the average wait time in 2018 is less than or equal to the average wait time in 2017)

Alternative hypothesis: H1: μ > 24 (the average wait time in 2018 is greater than the average wait time in 2017)

We will use a one-sample t-test with a significance level of α = 0.01 and degrees of freedom (df) = n-1 = 39.

The appropriate critical value is tα = t0.01,39 = 2.423.

To calculate the test statistic, we first need to find the sample mean and standard deviation:

x = (24+57+6+18+36+52+48+51+18+49+47+53+42+2+36+18+23+34+11+48+17+51+7+27+42+3+52+14+29+43+12+36+8+5+41+27+39+15+4+35)/40 = 31.6

s = √((∑(xi - x)²)/(n-1)) = 16.77

The test statistic is:

t = (x - μ) / (s / √(n)) = (31.6 - 24) / (16.77 / √(40)) = 2.44

Since the test statistic t = 2.44 is greater than the critical value tα = 2.423, we reject the null hypothesis.

b.

Using Excel, we can calculate the p-value for the test statistic t = 2.44 with the formula "=TDIST(2.44,39,1)", which gives a p-value of 0.010.

the precise p-value for this test is 0.010. Since the p-value is less than the significance level α = 0.01, we reject the null hypothesis and conclude that there is sufficient evidence to suggest that the average number of days appointments are booked in advance has increased since 2017.

Hence, the average number of days appointments are booked in advance has increased since 2017.

According to the given equation, the number of bottles that the vendor sold today before raising the price is; 8 bottles

In equation for the total amount collected T = 12 + 1.75n, it means that every additional bottle sold at the new price brings in $1.75 dollars:

Therefore, the per-bottle price after the $0.25 price increase would be $1.75. The per-bottle price before the price increase would be;

$1.75 - $0.25 = $1.50

When n = 0, we have;

T = 12 + 1.75(0)

T = $12

Thus, before any bottle was sold the total price collected was $12 before any bottle was sold at the new price.

Thus, the number of bottles sold at that price = 12/1.5 = 8 bottles

Statistical power is a measure of the ability to reject the null hypothesis when it is false. It represents the probability of correctly identifying a true effect or relationship in a statistical hypothesis test.

A high statistical power indicates a greater likelihood of detecting a significant result if the null hypothesis is indeed incorrect. The power of a statistical test depends on several factors, including the sample size, the effect size (the magnitude of the true effect or difference), the chosen significance level (often denoted as α), and the variability or noise in the data. Increasing the sample size or effect size generally increases the statistical power, while a lower significance level or higher variability decreases it.

Power analysis is commonly used to determine an appropriate sample size for a study, ensuring that it is adequately powered to detect the desired effect. A higher power is desirable as it reduces the chances of a Type II error (failing to reject the null hypothesis when it is false) and increases the chances of correctly detecting real effects or relationships.

The expression that represents the side length of the square pool is 2x² + 36x - 1120 = 0. The side length of the square pool is x = 16.31 feet.

Let's denote the side length of the square pool as x.

The walkway on two opposite sides of the pool is 8 feet, which means that the overall length of the pool and walkway on those sides is x + 8 + 8 = x + 16.

Similarly, x + 10 + 10 = x + 20.

The total area covered by the pool and walkway is given as 1,440 square feet.

Total Area = Pool Area + Walkway Area

The area of the square pool is x², and the area of the walkway is the difference between the total area and the pool area:

Walkway Area = Total Area - Pool Area

Substituting the values, we have:

1440 = x² + (x + 16)(x + 20)

1440 = x² + (x² + 36x + 320)

Combining like terms:

1440 = 2x² + 36x + 320

2x² + 36x + 320 - 1440 = 0

2x² + 36x - 1120 = 0

After solving, we get:

\(x=-9+\sqrt{641},\:x=-9-\sqrt{641}\)

Take positive value:

\(x=-9+\sqrt{641},\\x = -9+25.31\\x = 16.31\)
