Step-by-step explanation:

The average movie ticket cost in Switzerland and Japan each of these​ countries is 46.97.

Let's assume that the average cost of a movie ticket in Japan is x, and the average cost of a movie ticket in Switzerland is y.

According to the problem statement, we can write two equations based on the given information:

3x + 2y = 78.5 ...(1)

2x + 3y = 74.1 ...(2)

We can solve these equations simultaneously to find the values of x and y. Here's how:

Multiply equation (1) by 2 and equation (2) by 3, then subtract equation (1) from equation (2):

(2x + 3y) - 2(3x + 2y) = 74.1 - 2(78.5)

Simplifying this equation, we get:

-y = -109.3

Therefore, y = 109.3.

Now substitute y = 109.3 into either equation (1) or (2) and solve for x:

3x + 2(109.3) = 78.5

Simplifying this equation, we get:

3x = -140.9

Therefore, x = -46.97.

However, we cannot have negative ticket prices.

Therefore, the average cost of a movie ticket is 46.97.

Therefore, we can say that after studying 2.5 hours, a student should expect a quiz score of 81.6 based on the line of best fit.

A line of best fit, also known as a trend line, is a straight line that is drawn through a scatter plot to represent the general trend or pattern of the data. It is used to show the relationship between two variables, usually the independent variable (x) and the dependent variable (y), by fitting a line that comes as close as possible to all the data points. The line of best fit can be used to make predictions about future data points or to estimate values of the dependent variable for certain values of the independent variable. The most common method for finding the line of best fit is the method of least squares, which minimizes the sum of the squared differences between the actual data points and the predicted values of the dependent variable on the line.

Here,

The point (2.5, 81.6) represents a data point on the coordinate axes, where the x-coordinate of 2.5 represents the number of hours studied and the y-coordinate of 81.6 represents the quiz score earned by a student who studied for 2.5 hours.

Based on the line of best fit that the math teacher drew, we can use this point to estimate the quiz score for other students who also study for 2.5 hours. The line of best fit is a straight line that passes through the average point of all the data points and is used to predict one variable (quiz score) based on another variable (hours studied).

A. The derivative of f'(x) = 26x + 5is 26x + 5

B. Slope at x = 2 is 57

Slope at x = 3 is 83

c. The equation of the tangent line at x = 3 is y - 122 = 83(x - 3), or y = 83x - 179.

D. The value of x where the tangent line is horizontal is x = -5/26.

(A) f'(x) = 26x + 5.

It should be noted that to find the derivative of f(x), we apply the power rule and the constant multiple rule:

f'(x) = d/dx (13x²+5x)

= d/dx (13x²) + d/dx (5x)

= 26x + 5

(B) ain this case, to find the slope of the graph of f(x) at x = 2 and x = 3, we plug these values into the derivative:

Slope at x = 2: f'(2) = 26(2) + 5 = 57

Slope at x = 3: f'(3) = 26(3) + 5 = 83

(C) Based on the information, to find the equation for the tangent line at x = 2 and x = 3, we use the point-slope form of a line:

Tangent line at x = 2:

We know the slope is 57, and the point (2, f(2)) is on the line.

Plugging in x = 2 to f(x) gives us f(2) = 13(2)² + 5(2) = 58.

So the equation of the tangent line at x = 2 is y - 58 = 57(x - 2), or y = 57x - 56.

Tangent line at x = 3:

We know the slope is 83, and the point (3, f(3)) is on the line.

Plugging in x = 3 to f(x) gives us f(3) = 13(3)² + 5(3) = 122.

So the equation of the tangent line at x = 3 is y - 122 = 83(x - 3), or y = 83x - 179.

D. In order to find where the tangent line is horizontal, we need to find where the slope is equal to zero. Setting f'(x) = 0 and solving for x gives:

f'(x) = 26x + 5 = 0

x = -5/26

Therefore, the only value of x where the tangent line is horizontal is x = -5/26.

In the exponential decay, A) r = -0.0839 , B) r = -8.39% , C) Value=$11,800.

What is exponential decay?

The term "exponential decay" in mathematics refers to the process of a constant percentage rate reduction in an amount over time. It can be written as y=a(1-b)x, where x is the amount of time that has passed, an is the initial amount, b is the decay factor, and y is the final amount.

To find the annual rate of change between 1992 and 2006, we can use the formula:

r = [tex](V_2/V_1)^{1/n}-1[/tex]

where V1 is the initial value, V2 is the final value, and n is the number of years between the two values.

=>r = -0.0839

Therefore, the rate of change between 1992 and 2006 is -0.0839.

To express the rate of change in percentage form, we can multiply the result from part A by 100:

=>r = -0.0839 x 100

=> r = -8.39%

Therefore, the rate of change between 1992 and 2006 is a decrease of 8.39%.

To find the value of the car in the year 2009, we can assume that the value continues to drop at the same percentage rate as calculated in part A.

From 2006 to 2009, there are 3 years. So, using the formula for exponential decay, we have:

where V0 is the value in 2006, r is the rate of decrease, and n is the number of years between 2006 and 2009.

=>V = 11792.51

Therefore, the value of the car in the year 2009 would be approximately $11,800 (rounded to the nearest $50).

The area of the triangle is 3 square units whose vertices are (-3,1), (1,1) and (1,4). We will use distance formulae in this question.

To find the area of a triangle whose vertices are (-3,1), (1,1), and (1,4), we can use the formula for the area of a triangle:

Area = 1/2 * base * height

where the base and height are perpendicular and are formed by any two sides of the triangle.

To apply this formula, we can choose the line segment between (1,1) and (1,4) as the base of the triangle, since it is a vertical line and therefore has a length equal to the height of the triangle. The length of this line segment is 4 - 1 = 3 units.

Next, we need to find the length of the perpendicular segment from the point (-3,1) to the line containing the base. To do this, we can use the formula for the distance between a point and a line:

distance = [tex]|ax + by + c| / \sqrt{(a^2 + b^2)[/tex]

where a, b, and c are the coefficients of the equation of the line and x, y are the coordinates of the point.

In this case, the equation of the line containing the base is x = 1, so a = 1, b = 0, and c = -1. Plugging in the coordinates of (-3,1), we get:

distance = [tex]|1*(-3) + 0*(1) - 1| / \sqrt{(1^2 + 0^2)} = 2[/tex]

Therefore, the height of the triangle is 2 units.

Finally, we can plug these values into the formula for the area of a triangle to get:

Area = 1/2 * base * height = 1/2 * 3 * 2 = 3

So the area of the triangle is 3 square units.

Answer:

Apple Pie = 66.67%

Cherry Pie = 16.67%

Peach Pie = 16.67%

A possible distribution of pie percentages could be 66.67% apple, 16.67% cherry, and 16.67% peach.

Step-by-step explanation:

Let's assume that the bakery has 1 peach pie. Then, according to the problem statement, the bakery has 4 apple pies.

So, the total number of pies is 1 + 4 + 1 = 6.

To find the percentage of each type of pie, we need to divide the number of each type of pie by the total number of pies and multiply by 100%.

Percentage of apple pies: (4/6) x 100% = 66.67%

Percentage of cherry pies: (1/6) x 100% = 16.67%

Percentage of peach pies: (1/6) x 100% = 16.67%

Therefore, a possible distribution of pie percentages could be 66.67% apple, 16.67% cherry, and 16.67% peach.

It is important to note that this is just one possible distribution based on the information given in the problem. If we were given different information, such as the total number of pies, the percentages could be different.

For the regression coefficient, the value of bvu is 0.8.

Regression coefficient is a measure of the relationship between two variables in a regression analysis. It represents the degree of change in one variable for a unit change in another variable.

Recall that:

u = (x – a)/p

v = (y – c)/q

b[tex]_{yx}[/tex] = q/p × bvu

Given: u = (x-100)/2 and v = (y-200)/3

Thus, q = 3 and p = 2

Since the regression coefficient of Y on X = 1.2.

Thus, b[tex]_{yx}[/tex] = 1.2

b[tex]_{yx}[/tex] = q/p × bvu

The number of phone calls received in the second month is 25% more than the first month, which means:

Number of phone calls in second month = 1.25 x 4,264 = 5,330

To find the percent increase from the second month to the third month, we can use the percent increase formula:

Percent increase = (New value - Old value) / Old value x 100%

Using this formula, the percent increase from the second month to the third month is:

Percent increase = (6,396 - 5,330) / 5,330 x 100%

= 20%

Therefore, the percent increase in the number of phone calls from the second month to the third month is 20%.

Therefore, the completed statement is: The circumference of the base of Figure 2 is 9π inches, and the area of the base of Figure 2 is 20.25π square inches.

Area is a measure of the size of a two-dimensional surface or region, typically expressed in square units. It is the amount of space inside a closed shape, such as a square, rectangle, triangle, circle, or any other shape with a well-defined boundary. The concept of area is used in many areas of mathematics, science, and engineering, such as geometry, calculus, physics, and architecture. For example, engineers need to calculate the area of materials, such as the cross-sectional area of a pipe or the surface area of a building, in order to design structures that are strong, efficient, and safe.

Here,

The missing information in the statement can be found by using the given dimensions of the cylinders.

Figure 1 has a height of 9 inches and a radius of 4.5 inches.

Figure 2 is similar to Figure 1, so its height and radius are proportional to those of Figure 1. Let the height of Figure 2 be h inches and the radius be r inches. Then we have:

h/r = 9/4.5 = 2

So the height of Figure 2 is twice the radius.

The circumference of the base of Figure 2 is 2πr, which is equal to 2π(4.5) = 9π inches.

Step-by-step explanation:

The cylinders are similar, not congruent. That means the shape is the same but the values are not. The radius of figure 1 ( 4.5 in ) is half of figure 1's height ( 9 in ).

Plug 2.5 into the circumference and area formulas and you have figure 2's circumference and circle area.

Answer:

Without an image or a more detailed description of the diagram, it's difficult to provide an exact answer to this problem. However, we can use some logical reasoning to try to solve it.

Let's assume that the three lines of three numbers are arranged in a Tic-Tac-Toe grid, like this:

CSS

Copy code

A B C

D E F

G H I

We know that the product of the three numbers in each line is the same. Let's call this product "P". Then we can write:

CSS

Copy code

A * B * C = P

D * E * F = P

G * H * I = P

If we divide the second equation by the first equation, we get:

CSS

Copy code

(D * E * F) / (A * B * C) = 1

Since all the numbers are single-digit, this means that either D or F is equal to A, B, C, or 1. If D or F is equal to 1, then E is also equal to 1, which means that the entire middle row is filled with 1s, and that cannot be the case since all the numbers are different.

Therefore, we can assume that either D or F is equal to one of the numbers in the top row. Without further information, we cannot determine which one it is, but we know that the product of the numbers in the bottom row must be divisible by the product of the numbers in the top row. This means that the number in the circle containing the question mark must be a factor of this product, and it must be different from all the other numbers in the diagram.

Again, without more information, we cannot determine the exact number in the circle containing the question mark, but this logic should help narrow down the possibilities.
