Let the original price of the item be X.

In one week, the price is halved and becomes (1/2)X.

In two weeks, the price is halved again and becomes (1/4)X, which is only 75% off.

Answer: The answer is B

Step-by-step explanation:

Look at A- You can see that it wants you to go to English and see that 50 freshmen chose english. Then, you go to undecided, you see that it has 50 freshmen who chose it as well. They are the same, so it is false.

Look at B- You can see that it wants you to go to Education and see that 60 people chose Education. Then you go to both Science or other and see that they are both less than Education. So, this statement would be correct.

Look at C- You can see that it wants you to go to business or Education and see that 45 people chose business and 60 people chose education. Go to science, 35 people chose science and 40 chose engineering. This is false.

Look at D- 45 people chose business as their major and 50 chose english as their major, so no this wouldn't be correct because 45 if less than 50 and it says that it would be greater than 50.

So, B would be the correct answer to this problem.

4)  the distribution of the sample proportion of the 125 taxpayers that used the computer software to do their taxes is n(0.34, 0.0424) - option A

5)  the probability that between 28% and 40% of the taxpayers from the sample of 125 used computer software to do their taxes is pnorm(0.4,0.34,0.0424) - pnorm(0.28,0.34,0.0424) - Option A

4) Given data:

P = 0.34 and n = 125

Since, np = 0.34 * 125 = 42.5 > 10

& n(1 - p) = 125 * 0.66 = 82.5 > 10

Therefore, the normal distribution can be used here:

Mean is μp = p = 0.34

The standard Deviation is σp = \(\sqrt \frac{P(1-p)}{n} = \sqrt\frac{(0.34)(0.66)}{125} = 0.0424\)

The distribution of sample proportion will be;

N (0.34, 0.0424)

Therefore, option (a) is correct that is n(0.34, 0.0424)

5) The likelihood that between 28% and 40% of the 125 taxpayers in the sample used tax preparation software is calculated as follows:

pnorm (0.4, 0.34. 0.0424) - pnorm (0.28, 0.34, 0.0424)

Therefore, option A is correct that is pnorm(0.4,0.34,0.0424)-pnorm(0.28,0.34,0.0424)

To find the price at which the designer will sell the maximum number of shirts, we need to determine the vertex of the quadratic function representing the number of shirts sold.

The equation for the number of shirts sold is given by:

S = -4x^2 + 80x - 76

This is a quadratic function in the form of:

S = ax^2 + bx + c

To find the price at which the maximum number of shirts is sold, we need to locate the vertex of the quadratic function. The x-coordinate of the vertex can be found using the formula:

x = -b / (2a)

In this case, a = -4 and b = 80. Plugging in these values, we can calculate the x-coordinate:

x = -80 / (2*(-4))

x = -80 / (-8)

x = 10

Therefore, the designer will sell the maximum number of shirts at a price of $10. Hence, the correct option is c) $10.

The expression for the total volume of the building is V = L × W × H.

Volume is defined as the space occupied within the boundaries of an object in three-dimensional space.

To write an expression for the total volume of a building, we'll need to consider the dimensions of the building: length (L), width (W), and height (H). The volume of a rectangular building can be calculated using the formula:

Total Volume (V) = Length (L) × Width (W) × Height (H)

So, the expression for the total volume of the building is V = L × W × H.

Step-by-step explanation:

You cannot have the same number in your domain twice.

To find ln(x³y) in terms of u and v, we can use the properties of logarithms. ln(x³y) can be rewritten as ln(x³) + ln(y), and using the property ln(a^b) = bˣ ln(a), we have 3ln(x) + ln(y) = 3u + v.

To find ln(x³y) in terms of u and v, we can use the properties of logarithms. ln(x³y) can be rewritten as ln(x³) + ln(y), and using the property ln(a^b) = bˣ ln(a), we have 3ln(x) + ln(y) = 3u + v.

The domain of the function f(x) = ln(x-3) is x > 3, since the natural logarithm is undefined for non-positive values. The x-intercept occurs when f(x) = 0, so ln(x-3) = 0, which implies x - 3 = 1. Solving for x gives x = 4 as the x-intercept.

There are no vertical asymptotes for the function f(x) = ln(x-3) since the natural logarithm is defined for all positive values. However, the graph approaches negative infinity as x approaches 3 from the right, indicating a vertical asymptote at x = 3.

To sketch the graph of f(x) = ln(x-3), we start with the x-intercept at (4, 0). We can plot a few more points by choosing values of x greater than 4 and evaluating f(x) using a calculator.

As x approaches 3 from the right, the graph approaches the vertical asymptote at x = 3. The graph will have a horizontal shape, increasing slowly as x increases. Remember to label the axes and indicate the asymptote on the graph.

The translation from the triangle ABC to triangle A'B'C' is 3 units right and 2 units up.

A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.

Given that,

The coordinates of triangle ABC are A(-3, 1), B(-1, 2) and C(1, 1)

The coordinates of triangle A'B'C' are A'(0, 3), B'(2, 4) and (4, 3).

When the shape is moved towards the right by k units, then replace x with x + k.

When the shape is moved up by k units, then replace y with y + k.

A(-3, 1)→A'(-3+3, 1+2)

B(-1, 2)→B'(-1+3, 2+2)

C(1, 1)→C'(1+3, 1+2)

Answer:

usage patterns are a variable used in market segmentation.

Step-by-step explanation:

Usage patterns are a variable used in behavioral segmentation.

Behavioral segmentation is a marketing strategy that divides a market into different segments based on consumer behavior, specifically their patterns of product usage, buying habits, and decision-making processes. This segmentation approach recognizes that customers with similar behavioral characteristics are likely to exhibit similar preferences and respond in a similar manner to marketing initiatives.

Usage patterns, as a variable, help marketers understand and classify customers based on how they interact with a product or service. This can include factors such as the frequency of product usage, the amount of product used, the timing of purchases, brand loyalty, product benefits sought, and other behavioral indicators.

By analyzing usage patterns, marketers can identify distinct segments within their target market and tailor marketing strategies to meet the unique needs and preferences of each segment. This enables companies to develop more targeted marketing campaigns, optimize product offerings, improve customer satisfaction, and drive customer loyalty.

Overall, behavioral segmentation, including the consideration of usage patterns, allows companies to better understand and connect with their customers by aligning their marketing efforts with specific behaviors and motivations.

The proportion that is correct to find the value of x in the similar triangles is: B. x/20 = 9/15.

For any two triangles that are similar to each other, their corresponding sides will have lengths that are proportional to each other, which means they have the same ratio.

The triangles as shown in the image attached below are said to be similar to each other, this means they have side lengths that are proportional to each other or their corresponding sides will have proportional lengths.

Therefore, we will have the following proportion if we intend to find the value of x in the image given:

x corresponds to 20 while 9 corresponds to the side that measures (9 + 6) 15.

To find the area of the region within both of the circles r = 3 cos(θ) and r = 3 sin(θ), we can use a double integral. The region is defined in polar coordinates, so we need to integrate over the appropriate range of θ and r.

The first step is to determine the bounds of integration. Since both circles have a radius of 3, we can set up the following inequalities to find the limits of θ:

0 ≤ θ ≤ π/4 (from r = 3 sin(θ))

π/4 ≤ θ ≤ π/2 (from r = 3 cos(θ))

Next, we need to determine the limits of r. From the equation r = 3 sin(θ), we have 0 ≤ r ≤ 3 sin(θ). From the equation r = 3 cos(θ), we have 0 ≤ r ≤ 3 cos(θ). However, since we are considering the region within both circles, the appropriate limits for r are determined by the smaller of the two functions, which in this case is r = 3 sin(θ). So we have 0 ≤ r ≤ 3 sin(θ).

The double integral to find the area of the region is then given by:

Area = ∬ R dA = ∫[0, π/2]∫[0, 3 sin(θ)] r dr dθ

Evaluating this double integral will give us the area of the region within both circles.

Answer:

a. To find the margin of error and interval estimate for the number of eligible people under 20 years old who had a driver's license in 1995, we can use the formula for a confidence interval for a proportion:

margin of error = zsqrt(p(1-p)/n)

where z is the z-score corresponding to the desired level of confidence (95% confidence corresponds to a z-score of 1.96), p is the sample proportion (0.639), and n is the sample size (1200).

Plugging in the values, we get:

margin of error = 1.96sqrt(0.639(1-0.639)/1200) = 0.0261 (rounded to four decimal places)

To find the interval estimate, we can use the formula:

interval estimate = p ± margin of error

Plugging in the values, we get:

interval estimate = 0.639 ± 0.0261 = (0.6129, 0.6651) (rounded to four decimal places)

b. To find the margin of error and interval estimate for the number of eligible people under 20 years old who had a driver's license in 2016, we can use the same formulas with p = 0.417 (the sample proportion for 2016) and n = 1200:

margin of error = 1.96sqrt(0.417(1-0.417)/1200) = 0.0294 (rounded to four decimal places)

interval estimate = 0.417 ± 0.0294 = (0.3876, 0.4464) (rounded to four decimal places)

c. The margin of error is not the same in parts (a) and (b) because the sample proportion for 2016 (0.417) is smaller than the sample proportion for 1995 (0.639). As a result, the standard error (which is the square root of p*(1-p)/n) is larger for the 2016 sample than for the 1995 sample, which leads to a larger margin of error for the 2016 estimate.
