A) The appropriate hypothesis test to determine if there is a statistically significant association between sales and profits is B. H_0: There is no linear relationship between sales and profits, beta_1 = 0. H_A:

There is a linear relationship between sales and profits, beta_1 ≠ 0. This test will determine if there is a linear relationship between the two variables, regardless of the direction of the relationship (positive or negative).

B) The conclusion of this test would be based on the p-value obtained from the test. If the p-value is less than the significance level of 0.05, we would reject the null hypothesis and conclude that there is a statistically significant linear relationship between sales and profits.

If the p-value is greater than 0.05, we would fail to reject the null hypothesis and conclude that there is not enough evidence to suggest a linear relationship between the two variables.

Answer:

[tex]\dfrac{223}{64}=3.484375[/tex]

Step-by-step explanation:

The Riemann sum is a method by which we can approximate the area under a curve using a series of rectangles.

The Lower Riemann Sum uses the minimum height of the rectangle on each subinterval.  

As the Lower Riemann Sum is entirely below the curve, it is an underestimation of the area under the curve.

The number of partitions is the number of rectangles used.  

Partitions can be of equal length or not of equal length.

Given:

The given partition divides the interval [0, 1] into 3 subintervals:

To calculate the areas of the rectangles, multiply the width of each rectangle by its height.

The width is the difference between the x-values of each subinterval.

The height is the minimum value of the function across the subinterval. For the given function, this is the value of the function for the right side of the subinterval.

First rectangle [0, 1/2]:

[tex]\begin{aligned}\implies \left(\dfrac{1}{2}-0\right) \cdot f\left(\dfrac{1}{2}\right)&=\dfrac{1}{2} \cdot \left(4-\left(\dfrac{1}{2}\right)^2\right)\\\\&=\dfrac{1}{2} \cdot \dfrac{15}{4}\\\\&=\dfrac{15}{8}\end{aligned}[/tex]

Second rectangle [1/2, 3/4]:

[tex]\begin{aligned}\implies \left(\dfrac{3}{4}-\dfrac{1}{2}\right) \cdot f\left(\dfrac{3}{4}\right)&=\dfrac{1}{4} \cdot \left(4-\left(\dfrac{3}{4}\right)^2\right)\\\\&=\dfrac{1}{4} \cdot \dfrac{55}{16}\\\\&=\dfrac{55}{64}\end{aligned}[/tex]

Third rectangle [3/4, 1]:

[tex]\begin{aligned}\implies \left(1-\dfrac{3}{4}\right) \cdot f\left(1\right)&=\dfrac{1}{4} \cdot \left(4-\left(1\right)^2\right)\\\\&=\dfrac{1}{4} \cdot 3\\\\&=\dfrac{3}{4}\end{aligned}[/tex]

Therefore, the Lower Reimann Sum for the given function over the given interval and partitions is the sum of the area of the rectangles:

[tex]\implies \dfrac{15}{8}+\dfrac{55}{64}+\dfrac{3}{4}=\dfrac{223}{64}=3.484375[/tex]

The price of an adult ticket is $14 and the price of a children's ticket is $8.

Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.

Let x be the price of an adult's ticket and y be the price of a children's ticket.

One family bought 1 adult ticket and 3 children's tickets for a total of $38.

x + 3y = 38

Another family bought 2 adult tickets and 4 children's tickets for a total of $60.

2x + 4y = 60

We have two linear equations in two variables here.

x + 3y = 38

2x + 4y = 60

Multiplying the first equation throughout by 2, we get,

2x + 6y = 76

Subtracting the second equation 2x + 4y = 60 from the multiplied first equation 2x + 6y = 76, we get,

2x + 6y - (2x + 4y) = 76 - 60

2y = 16

y = 8

x + 3y = 38 ⇒ x = 38 - 24 = 14

Hence the price of an adult's ticket and children's ticket is $14 and $8 respectively.

Parallel lines are coplanar infinite straight lines that do not cross at any point in geometry. Parallel planes are planes that never intersect in the same three-dimensional space. Parallel curves are those that do not touch or intersect and maintain a constant minimum distance. Parallel lines are lines that are always the same distance apart in a plane. Parallel lines never cross. Perpendicular lines are those that connect at a straight angle (90 degrees). Parallel lines in geometry are two lines in the same plane that are at equal distance from each other but never intersect. They can be both horizontal and vertical in orientation.

Answer: X = 25

Step-by-step explanation: We can use the Law of Cosines to solve for the remaining side of the triangle, which we'll call "x".

The Law of Cosines states that:

c^2 = a^2 + b^2 - 2ab * cos(C)

In this triangle, we are trying to find side "x" (c) so we can use the following equation:

x^2 = 20^2 + 17^2 - 2(20)(17)cos(H)

Now we can substitute the known values into the equation:

x^2 = 400 + 289 - 680cos(H)

Now we can solve for x by taking the square root of both sides:

x = sqrt(400 + 289 - 680cos(H))

= sqrt(689 - 680cos(H))

= sqrt(9 + 289cos(H))

Alternatively, we can use Law of Sines to solve for side x.

The Law of Sines states that a/sin(A) = b/sin(B) = c/sin(C)

Knowing all the angles in the triangle we can use the following equation

x/sin(K) = 20/sin(P) = 17/sin(H)

Now we can substitute the known values into the equation

x = (20*17)/sin(H)

In both case we get x = 25.

Rounded to the nearest inch, the length of side PR is 75 inches.

B. The inverse function is given as follows: [tex]f^{-1}(x) = \sqrt{0.5(x + 8)} + 4[/tex]

C. The composition of the function with it's inverse results in x, hence they are inverse.

The quadratic function for this problem is defined as follows:

y = 2(x - 4)² - 8.

The classifications regarding function and one-to-one are given as follows:

The inverse can only be obtained when the function is one-to-one, hence a possible domain is given as follows:

x ≥ 4.

(as the vertex is at x = 4).

To obtain the inverse, first we must exchange the variables x and y, hence:

x = 2(y - 4)² - 8.

Now we must isolate the variable y, as follows:

2(y - 4)² = x + 8

(y - 4)² = 0.5(x + 8)

[tex]\sqrt{(y - 4)^2} = \sqrt{0.5(x + 8)}[/tex]

[tex]y - 4 = \sqrt{0.5(x + 8)}[/tex]

[tex]f^{-1}(x) = \sqrt{0.5(x + 8)} + 4[/tex]

The composition of the two functions is given as follows:

Answer: To find the solution of a system of equations, we can either use substitution or elimination method.

For this system of equations, we can use the substitution method:

First, we solve one equation for one of the variables. For example, we can solve the first equation for y: y = -2x - 4

Then, we substitute this expression of y into the second equation and solve for x: 1/2x + 6 = -2x - 4

We can simplify this equation by adding 2x to both sides: 1/2x + 2x + 6 = -4

And then by adding 6 to both sides: 1/2x + 2x + 12 = 2

And then by multiplying both sides by 2: x + 4x + 24 = 4

And then by simplifying: 5x = -20

Finally, we find x = -4

Now that we have found x, we can substitute it back into one of the equations to find y:

y = -2(-4) - 4 = 8 - 4 = 4

So the solution of the system of equations is x = -4 and y = 4

We can check that this solution satisfies both equations.

Answer:

The percentage of increase in price is 175%. To calculate this, you can subtract the cost price (in this case, $1) from the selling price ($2.75) to find the profit ($1.75). Then divide that profit by the cost price and multiply by 100 to express it as a percentage.

$2.75 - $1 = $1.75

$1.75/$1 * 100 = 175%

If you want to calculate the percentage increase in price, use the formula:

Percentage Increase = (New Price - Original Price) / Original Price x 100

In this case, the original price is $1 (the price of buying the cards) and the new price is $2.75 (the price of selling the cards). So, plugging these values into the formula:

Percentage Increase = (2.75 - 1) / 1 x 100 = 175%

The percentage increase in price is 175%.

The term "rate of change" (ROC) describes the rate at which something changes over time. Thus, it is not the amount of individual changes themselves but rather the acceleration or deceleration of changes.

When something changes over time, it does so at a certain rate, or ROC. Therefore, rather than the size of each change individually, it is the rate of change—or, more specifically, its acceleration or deceleration. Rate of change is a concept in finance that is used to comprehend price returns and pinpoint trends' momentum.

A ratio is used to express the rate of change, which contrasts the values of the y and x variables. The slope of the line represents the rate of change if it is linear, constant, and so on. Positive, negative, zero, or undefinable slopes are all possible for lines.
