write down the formula to find out profit percent
​

An equation for each company representing the total sponsorship money earned (y) you can make for each day of the trip (x) are as follows;

In order to write the required system of linear equations, we would have to use the point-slope form formula as follows;

y - y₁ = m(x - x₁)

Where:

Next, we would determine the linear equation representing the total sponsorship money earned for Takis Chips:

y - y₁ = m(x - x₁)

y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

y - 480 = (655 - 480)/(26 - 16)(x - 16)

y - 480 = 175/10(x - 16)

y - 480 = 17.5(x - 16)

y = 17.5x - 280 + 480

y = 17.5x + 200.

For Monster energy drink, the linear equation is given by;

y - 300 = (755 - 300)/(23 - 10)(x - 10)

y - 300 = 455/13(x - 10)

y - 300 = 35(x - 10)

y = 35x - 350 + 300

y = 17.5x - 150.

For Snickers candy bars, the linear equation is given by;

y - 100 = (400 - 100)/(15 - 9)(x - 9)

y - 100 = 300/6(x - 9)

y - 100 = 50(x - 9)

y = 50x - 450 + 100

y = 50x - 350.

The correct answer is a. H0: u≥2 hours and H1:u<2 hours. When testing a right-tailed hypothesis using a significance level of 0.025, a sample size of n=13, and with the population standard deviation unknown, the critical value is as follows:

To determine the critical value, we need to use the t-distribution since the population standard deviation is unknown.

Using a t-distribution table or calculator with 12 degrees of freedom (n-1), a one-tailed test, and a significance level of 0.025, the critical value is 2.1604.

If the test statistic is greater than or equal to this value, we can reject the null hypothesis in favor of the alternative hypothesis, which is a right-tailed hypothesis.

This glass is most likely a cylinder. To find the volume of a cylinder you take the area of the circle base and multiply it by the height.

To find the area of a circle, you square the radius and multiply it by pi (we will use 3.14 for pi).

Our radius is 3cm.

3

We square it.

3²=9

Multiply by 3.14.

9×3.14=28.26

Now that we have our circle base area, we multiply it by the height (7 cm).

28.26×7= 197.82

This is how many cubic centimeters the glass can hold if it is completely full. However, we want half full, so we can just divide by 2.

197.82/2=98.91

We can also multiply our circle base by 3.5, which will give us half of the full height.

So, the height of the water is 3.5 cm and the volume of the water is 98.1 cm³.

Since the probability of drawing a blue marble in the first draw and the probability of drawing a blue marble in the second draw are the same, the statement is true.

The probability of drawing a blue marble in the first draw is:

P(First marble is blue) = (number of blue marbles) / (total number of marbles)

P(First marble is blue) = 10 / (10 + number of red marbles)

Now, if we draw with replacement, we return the first marble to the jar before drawing the second one. Therefore, the number of blue marbles and the total number of marbles in the jar remains the same. Therefore, the probability of drawing a blue marble in the second draw is also:

P(Second marble is blue) = (number of blue marbles) / (total number of marbles)

P(Second marble is blue) = 10 / (10 + number of red marbles)

Since the probability of drawing a blue marble in the first draw and the probability of drawing a blue marble in the second draw are the same, the statement is true.

Step-by-step explanation:

Given that a telephone pole casts a shadow of 20 feet when the angle of elevation of the sun is directly away from the pole, the task is to determine the length of the pole to the nearest tenth of a foot.

We can use the concept of similar triangles to solve this problem. The telephone pole, the shadow, and the sun form two right triangles that are similar to each other. Let's assume the height of the pole is h feet. The length of the shadow is given as 20 feet. Since the angle of elevation of the sun is directly away from the pole, the angle between the shadow and the height of the pole is 90 degrees.

By considering the two similar triangles, we can set up a proportion: the length of the shadow / the height of the pole = the length of the adjacent side / the length of the opposite side. This can be written as 20 / h = tan(angle of elevation).To solve for h, we can rearrange the equation: h = 20 / tan(angle of elevation).

Since the angle of elevation is not given in the problem, we cannot calculate the exact length of the pole. However, if the angle of elevation is provided, we can substitute it into the equation to find the length of the pole to the nearest tenth of a foot.

If the null hypothesis is not rejected, we cannot conclude that there is a significant difference between the two time periods.

Assuming that the question is "Has real gross domestic product per capita significantly increased between 1988 and 1990?" We can use a paired-sample t-test to answer this question.

Here are the steps to conduct the paired-sample t-test:

Null hypothesis: The mean difference between the real gross domestic product per capita in 1988 and 1990 is zero. In other words, there is no significant difference between the two time periods.

Alternative hypothesis: The mean difference between the real gross domestic product per capita in 1988 and 1990 is not zero. In other words, there is a significant difference between the two time periods.

Determine the level of significance, alpha (α). Let's assume α = 0.05.

Calculate the difference between the two time periods (1990 - 1988) for each observation.

Calculate the mean and standard deviation of the differences.

Calculate the standard error of the mean difference (SEd) by dividing the standard deviation of the differences by the square root of the sample size.

Calculate the t-statistic by dividing the mean difference by the SEd.

Calculate the degrees of freedom (df) using the formula: df = n - 1, where n is the sample size.

Determine the critical t-value from the t-distribution table with df = n - 1 and α = 0.05.

Compare the calculated t-value with the critical t-value. If the calculated t-value is greater than the critical t-value, reject the null hypothesis. Otherwise, fail to reject the null hypothesis.

Interpret the results. If we reject the null hypothesis, we can conclude that there is a significant difference between the two time periods, and the direction of the difference can be determined by the sign of the mean difference.

Note: In order to conduct the paired-sample t-test, we need to assume that the differences are normally distributed and the variances of the two populations are equal.

After conducting the test, we can conclude whether there is a significant difference in real gross domestic product per capita between 1988 and 1990. If the null hypothesis is rejected, we can conclude that there is a significant difference between the two time periods. If the null hypothesis is not rejected, we cannot conclude that there is a significant difference between the two time periods.

Answer: graph it

Step-by-step explanation:

Step-by-step explanation:

I cannot draw here. but it is simple for you to do it yourself.

it is a linear function (highest exponent of x is 1). that means the graph of the function is a straight line.

and that means you just need 2 points, a ruler, a pen, and then you connect the 2 points (and extend the line left and right of the 2 points, as the graph goes on to infinity and beyond ...).

how do we find 2 points ?

by just thinking about 2 nice x-values and then calculate the corresponding y-values.

I always start with x = 0.

y = 5×0 + 1 = 1

so, the first point would be (0, 1).

but here, the y-axis has only steps of 2.

so, to be as precise a possible, I pick x=1.

y = 5×1 + 1 = 5 + 1 = 6.

so, our first point is (1, 6).

the next x that will give us an even y is x=3.

y = 5×3 + 1 = 15 + 1 = 16

so, our second point is (3, 16).

now, make dots at (1, 6) and (3, 16), and then draw the line as described above.

Martin is building a model. He cuts two pieces of wood that are each \(6\frac{1}{3}\) inches long from a board with a total length of 18 inches.  What is the length, in inches, of the remaining part of the board?

Answer : The length of the remaining part of the board is \(5\frac{1}{3}\) inches.

Step-by-step explanation :

As we are given that:

Total length of the board = 18 inches

Length of each piece of wood cut from the board = \(6\frac{1}{3}\) inches = \(\frac{19}{3}\) inches

Length of 2 pieces of wood cut from the board = \(2\times \frac{19}{3}\) inches

                                                                               =  \(\frac{38}{3}\) inches

Length of the remaining part of the board = Total length of the board - Length of 2 pieces of wood cut from the board

Length of the remaining part of the board = \(18-\frac{38}{3}\) inches

                                                                      = \(\frac{54-38}{3}\) inches

                                                                      = \(\frac{16}{3}\) inches

                                                                      = \(5\frac{1}{3}\) inches

Therefore, the length of the remaining part of the board is \(5\frac{1}{3}\) inches.
