Answer:

(a) To find out how long it takes for Claudia to catch up with Cindy, we can first calculate the head start that Cindy had before Claudia started. Cindy had a head start of:

d = rt = 108 km/h x 1 h 40 min = 180 km

where d is the distance that Cindy traveled during the 1 hour 40 minutes (1.67 hours) between her departure and Claudia's departure, r is Cindy's speed, and t is the time she traveled.

When Claudia started, both Cindy and Claudia were 180 km away from Beach Town. The distance between them decreases at a rate equal to the difference in their speeds, which is:

124 km/h - 108 km/h = 16 km/h

So Claudia catches up at a rate of 16 km/h. The time it takes for Claudia to catch up is then:

t = d / r = 180 km / 16 km/h = 11.25 hours

However, we need to subtract the 1 hour 40 minutes (1.67 hours) that Cindy traveled before Claudia started to find the actual time Claudia took to catch up with Cindy:

t = 11.25 hours - 1.67 hours = 9.58 hours

Therefore, Claudia took about 9 hours and 35 minutes (0.58 x 60 minutes) to catch up with Cindy.

(b) When Claudia catches up with Cindy, they are both the same distance away from Beach Town. Cindy has already traveled 180 km when Claudia catches up, so the distance they are from Beach Town is:

600 km - 180 km = 420 km

Therefore, they were 420 km away from Beach Town when Claudia caught up with Cindy.

The mode would not change if the number 24 were added to the set, as it is still the number that appears most frequently in the set.

What is a mode in statistics?

In statistics, the mode is the value that appears most frequently in a set of data. In other words, it is the value that occurs with the highest frequency.

For the set of 5 numbers given: 24 58 24 24 53, the mode is 24 because it appears three times, which is more than any other number in the set.

If the number 24 were added to the set, then the set would become: 24 58 24 24 53 24. In this case, the mode would still be 24 because it still appears most frequently, now occurring four times in the set.

Hence, the mode would not change if the number 24 were added to the set, as it is still the number that appears most frequently in the set.

He can withdraw $114746.17 (approx.) at the end of each of the next 25 years and end up with zero in the account. The solution has been obtained by using the concept of present value of annuity.

What is present value of annuity?

With a specific rate of return, or discount rate, an annuity's present value is the current worth of its expected future payments. The present value of the annuity decreases with increasing discount rates.

We are given that uncle has $1,375,000 and wants to retire. He expects to live for another 25 years and to earn 7.5% on his invested funds.

Using present value of annuity,

Present value of annuity due = P + P [(1 - (1 + r)⁻⁽ⁿ⁻¹⁾) / r]

1375000 = P + P [(1 - (1+0.075)⁻⁽²⁵⁻¹⁾)/0.075]

1375000 = P [1 + 10.98297]

P = 1375000/11.98297

P = $114746.17 (approx.)

Hence, uncle can withdraw $114746.17 (approx.) at the end of each of the next 25 years.

A correlation coefficient based on an observational study can only measure the strength of the relationship between two variables, and it cannot be used to prove a cause-and-effect relationship.

Even if the correlation is close to -1 or +1, this does not necessarily mean there is a cause-and-effect relationship between the two variables—it could be due to chance. Similarly, if the scatterplot of the data has little vertical variation, this does not necessarily mean there is a cause-and-effect relationship. The only way to prove a cause-and-effect relationship is through a controlled experiment. Therefore, the correlation coefficient based on an observational study can never be used to support a claim of cause and effect.

The cone’s radius r in terms of x is x + 7

From the question, we have the following parameters that can be used in our computation:

Volume, V = 3πx^2 + 42πx + 147π

Height, h = 9

The volume of a cone is

V = 1/3πr^2h

Substitute the known values in the above equation, so, we have the following representation

1/3πr^2 * 9 = 3πx^2 + 42πx + 147π

So, we have

3πr^2 = 3πx^2 + 42πx + 147π

Divide by 3π

r^2 = x^2 + 14x + 49

So, we have

r = √(x² + 14x + 49)

Take the square roots of both sides

r = x + 7

The sample is not approximately normal because (50) (0.02) is not equal to or greater than 10.

The conditions for performing a significance test using a z-statistic require a sample size large enough to satisfy the Central Limit Theorem, which means that the sample should be approximately normal. In this case, the expected number of adults who own a motorcycle in the sample is only 1, which is less than the threshold of 10 needed for approximate normality. Therefore, the sample distribution is not normal, and a z-statistic cannot be used for hypothesis testing.

An acre is a unit of measurement used to quantify land area, and it is commonly used in the United States to measure the size of plots of land, farms, and estates. One acre is equal to 43,560 square feet.

To visualize an acre, imagine a rectangle that is approximately 208 feet by 209 feet, or a square that is approximately 209 feet on each side.

To convert acres to square feet, you can use the following formula:

1 acre = 43,560 square feet

Therefore, to convert acres to feet, you can simply multiply the acre value by 43,560. For example, if you want to convert 5 acres to square feet, you can use the following formula:

5 acres x 43,560 square feet per acre = 217,800 square feet

So 5 acres is equal to 217,800 square feet.

A graph is referred to be an interval graph if each of its vertices can be connected to a real line interval in such a way that two vertices are only connected if and only if the connected intervals have a nonempty intersection.

Given:

Our curve has a minimum at (-2.5, -12)

Our curve has a maximum at (0, - 3)  

We know that the curve crosses the x-axis at (-4, 0) and y-axis at (0, -3)

At the value x = -2.5 > (-4) the function is negative.

So, f(-2.5) = -12

f(-4) = 0

As a result, it is clear that the function is negative after f(x) crosses the x-axis at x = -4.

This implies that the function must be positive prior to that point.

Thus, the function > 0 for x values less than -4.

f(x) > 0 if x < -4

The retail price of the car at the dealership is $9,803.90. This means that the dealership is adding a markup of $1,453.90, or 17.4% of the cost, to sell the car to customers.

To find the retail price of the car at the dealership, we need to add 17.4% to the dealership's cost of $8,350. Here are the steps to do this calculation:

Multiply the cost of the car by the percentage markup as a decimal. To convert a percentage to a decimal, divide it by 100. So 17.4% as a decimal is 0.174.

Markup = $8,350 x 0.174 = $1,453.90

Add the markup to the cost of the car to get the retail price.

Retail Price = $8,350 + $1,453.90 = $9,803.90

Regression is a statistical procedure for determining the linear relationship between a number of variables. A simple regression model has one dependent variable and one independent variable [tex](y)[/tex]

It is used to forecast the amount of a dependent variable according to the results of one independent variable. [tex](x)[/tex]

The estimated least-squares line has the following shape :[tex]y=bo+b1x[/tex].

In this case, the dependent variable is, the independent variable is, the intercept is, and the slope coefficient is.

The slope of a linear regression describes how a unit change in x changes the y value.

When, the intercept represents the expected mean value of Y. When X never equals zero, the intercept has no intrinsic meaning.

Step  (1) The process of estimating the linear relationship between two or more variables is known as regression. Only if there is a linear relationship between both variables can a regression equation be used to predict future.

Linear regression is the most fundamental a kind of regression and is the most widely used proposed model. A regression line can be used to predict dependent variables based on independent variables.

Step: (2) Outliers have a significant impact on the slope of the regression line. Influential points are also referred to as outliers in regression analysis.

Outliers can have a significant impact on the regression equation, so remove any outliers that are recognized errors. Consider the effects of any known inconsistencies that are outliers.

Step 3: Because outliers can have a large impact on the regression line, they are also referred to as important and powerful points.

An outlier is a data point that is located far away first from remaining pieces of data. These are additionally known as influencing points. Outliers have a significant influence on the slope of something like the regression line.

What is a trapezoid?

A polygon with only one set of parallel sides is called a trapezoid. The parallel bases of a trapezoid are another name for these parallel sides. Trapezoids have two additional sides that are not parallel and are referred to as their legs.

Trapezoids are defined differently by different people. A trapezoid can have one and only one pair of parallel sides, according to one school of mathematics, while another contends that a trapezoid can have multiple pairs of parallel sides. If we take into account the second definition, then a parallelogram is also a trapezoid by that definition. However, the first definition excludes parallelograms from the definition of a trapezoid since it is one of the quadrilateral types that we have already mentioned.

2. The formula for the area of a trapezoid is 1/2 × (sum of parallel side) × height.

The length of one parallel side is 10 inches. The length of the other parallel side is (10+4+4) inches = 18 inches.

The height of the trapezoid is 14 inches

The area of the trapezoid is 1/2 ×(10 + 18) × 14

= 196 square inches.

3.

The formula for the area of a trapezoid is 1/2 × (sum of parallel side) × height.

The length of one parallel side is 5 ft. The length of the other parallel side is (5+3) ft = 8 ft.

The height of the trapezoid is 5 ft.

The area of the trapezoid is 1/2 ×(5 + 8) × 5

= 32.5 square ft.

4.

The area of a parallelogram is the product of height and base.

The length of the base is (2.5 yards + 6.5 yard) = 9 yards

The height of the parallelogram is 6 yards.

The area of the parallelogram is 9 yards × 6 yards

= 54 square yards

Each beg can cover 40 square yards field.

The number of begs that the farmer need is 56/40 = 1.4  ≈2
