Statisticians for a roadside assistance company interviewed 50,000 randomly selected United States (US) households. Of those, 15

Answer:

The answer is the scatter plot that displays a pronounced positive slope along the curve of best fit.

Step-by-step explanation:

A scatter plot illustrates the relationships between two variables for an individual. It is essentially a graph in which a best-fit curve is drawn to encapsulate the complete dataset. A scatter plot is considered to have a robust correlation if the correlation coefficient is near r = 1, indicating a very strong connection between the two variables.

A scatter plot exhibits a solid correlation when its data points are closely aligned to the line or curve of best fit.

For r = 1, the correlation is regarded as strong and positive.

Answer:

The exponential equation can be expressed as A = 600(1.04)^15

After 15 years, the value of the mutual fund will be $1,081

Step-by-step explanation:

The worth of the mutual fund after a specific number of years can be represented by the compound interest formula shown below;

A = P(1 + r/n)^nt

In this formula, A stands for the mutual fund's value after 15 years, P represents the principal amount invested, which is $600, r denotes the interest rate at 4% or 0.04 (thus, 4% = 4/100 = 0.04), n indicates the number of times compounding occurs per year (in this case, it is done once a year), and t represents the number of years, which is 15.

Now, substituting in these values gives us;

A = 600(1 + 0.04/1)^15

A = 600(1.04)^15

A = $1,081 approximately

The degree is positive and even

The degree is negative and odd

This is a useful question to answer. I believe there’s not a single place on earth that is free from some form of tax.

Tax is applicable only during transactions where money is exchanged, and it does not affect discounts.

If you decide to take the offer, the cost is determined by:

Cost for two pizzas = standard price - discount applied.

Cost for two pizzas = 2*10.50 - 2.00

Cost for two pizzas = 21 - 2

Cost for two pizzas = 19.00 dollars.

Now, you should add the sales tax to this amount. There are two methods to do this: the detailed method or the quicker method.

Detailed Method

Calculate the sales tax:

Tax = rate * total cost

Tax = (7.5/100) * 19

Tax = 1.425, don’t round yet.

Total Amount = total purchase + tax

Total Amount = 19.00 + 1.425 = 20.425. Now, round it off. The way to round when the last digit is 5 can vary; I usually round up, so my final answer would be 20.43 <<<<< This is the answer.

Quick Method

Final Cost = (Original Price - discount)*(1 + tax rate/100)

Final Cost = (21 - 2)*(1 + 7.5/100)

Final Cost = 19 * (1.075)

Final Cost = 20.425, which rounds to 20.43.

Answer:

P(R or G) = 0.3

Step-by-step explanation:

In the question, we are provided with the following information:

x:      BR       Y      R      BL     O     G

P(x):  0.1     0.2    0.1    0.2    0.2   0.2

Initially, we need to assess the distribution type.

This indicates it is a discrete probability distribution.

Next, we need to compute P(R or G)

Therefore, the likelihood of picking a red or green M&M is 0.3
