The circumference of a circle is 32π feet, which is the correct answer would be option (B).

The Circumference of a circle is defined as the product of the diameter of the circle and pi.

C = πd

where 'd' is the diameter of the circle

We have to determine the circumference of a circle whose radius is 16 feet

As per the question, we have

The radius of the circle r = 16 feet

Circumference of a circle = 2πr

Substitute the value of r in the above formula, and we get

Circumference of a circle = 2π(16)

Circumference of a circle = 32π

Hence, the correct answer would be an option (B).

Answer: The diver descended 20 meters below sea level and then ascended 8 meters.

Step-by-step explanation: The expression 2 + (-20) + 8 describes the diver's movements in relation to sea level. The first number, 2, represents the diver's initial position at sea level. The second number, -20, represents the diver's descent below sea level by 20 meters. The third number, 8, represents the diver's ascent back up to sea level. This can be interpreted as the diver starting at sea level, descending 20 meters below sea level, and then ascending 8 meters back up to sea level.

Option B is correct. It is a plot of the independent and dependent variables.

A scatter diagram is a type of plot or graph that uses Cartesian coordinates to display the values of two variables for a set of data. It is a simple yet powerful way to visualize the relationship between two variables.

The points on the plot represent the values of two variables, the independent variable (X-axis) and the dependent variable (Y-axis). Scatter diagrams provide a visual representation of the relationship between the two variables, which makes it easier to identify patterns such as linear or non-linear relationships.

They also can show correlations, or lack thereof, between two or more variables. Additionally, scatter diagrams can provide insight into the strength of the relationship between the two variables as well as how much of the variation in the dependent variable is explained by the independent variable. For example, a correlation coefficient of 1 indicates a perfect linear relationship, while a correlation coefficient of 0 indicates no relationship between the two variables.

Total bill that should be paid by Olive is $46.61. Olive's calculation is incorrect because she is applying the discount and tax to the original price of the clothes rather than to the discounted price.

A total bill is the final amount of money that is due for payment, usually for goods or services that have been provided. It is the sum of all charges, fees, taxes, and other expenses that have been incurred. The total bill may be presented as a single amount or as a breakdown of the various charges that make up the total.

The correct expression to calculate the total cost of the clothes would be:

Total cost = (Original price * (1 - Discount rate)) * (1 + Tax rate)

In this case, the original price is $54.50, the discount rate is 20%, and the tax rate is 7.5%. Plugging these values into the above expression gives us:

Total cost = (54.50 * (1 - 0.20)) * (1 + 0.075)

Total cost = (54.50 * 0.80) * 1.075

Total cost = $43.60 * 1.075

Step-by-step explanation:

Answer:

The correct answer is A (x+1)(7x-10).  

Step-by-step explanation:

To determine the dimensions of a rectangular poster that will cover an area represented by 7x² + 3x - 10, we need to find the factors of the expression 7x² + 3x - 10 that will give us the length and width of the poster.

One way to do this is to factor the expression 7x² + 3x - 10 using the difference of squares method. We can write the expression as follows:

7x² + 3x - 10 = (7x² + 3x) - 10

To factor (7x² + 3x) - 10, we can write the expression as the difference of squares:

(7x² + 3x) - 10 = (7x² + 3x + 10) - (10 + 10)

To simplify the expression, we can complete the square for the terms in parentheses:

(7x² + 3x + 10) - (10 + 10) = (7x² + 3x + 10) - 20

To complete the square, we need to add and subtract the square of half the coefficient of the x term, which is (3/2)² = 9/4. We can rewrite the expression as follows:

(7x² + 3x + 10) - 20 = (7x² + 3x + 10 + 9/4) - (20 - 9/4)

To simplify the expression, we can factor the terms in parentheses:

(7x² + 3x + 10 + 9/4) - (20 - 9/4) = [(7x² + 3x + 10 + 9/4) - (20 - 9/4)]

To simplify the expression further, we can factor out a common factor:

[(7x² + 3x + 10 + 9/4) - (20 - 9/4)] = (x + 1)(7x - 10)

From the given options, the expression that represents the area of the rectangular poster is (x+1)(7x-10), which is equivalent to 7x² + 3x - 10. We can verify this by multiplying (x+1)(7x-10) to get 7x² + 3x - 10. Therefore, the correct answer is A (x+1)(7x-10).

Answer:

The possible pairs of numbers that satisfy the given conditions are (x, y) = (4, 2) and (x, y) = (8, -2).

Step-by-step explanation:

To solve this problem, we can use algebra. Let's call the two numbers x and y. We are given that x + y = 6 and x^2 + y^2 = 28. We can square the equation x + y = 6 to get x^2 + 2xy + y^2 = 36. We can then subtract the equation x^2 + y^2 = 28 from the equation x^2 + 2xy + y^2 = 36 to get 2xy = 8. We can then divide both sides by 2 to get xy = 4.

We can then use the equation x + y = 6 to write x = 6 - y, which we can substitute into the equation xy =  to get (6 - y)y = 4. Solving this equation for y yields y = 2 or y = -2.

If y = 2, then x = 6 - y = 6 - 2 = 4, so the two numbers are x = 4 and y = 2. If y = -2, then x = 6 - y = 6 + 2 = 8, so the two numbers are x = 8 and y = -2. Therefore, the possible pairs of numbers that satisfy the given conditions are (x, y) = (4, 2) and (x, y) = (8, -2).

If the data display is strongly skewed right, it means that there are relatively more households with a higher number of children compared to households with a lower number of children. This means that the median value is likely to be higher than the mean value of 3 children per household.

Possible values for the median could be 4, 5, or even higher. It is not possible to determine the exact value of the median without more information about the distribution of the data. However, it is reasonable to assume that the median could be 4 or 5 children per household in this case.

Answer:

Step-by-step explanation:

Based on the given linear regression equation, Bill's score on the final exam would be calculated as follows:

y = 10 + 0.9 * 90 = 98

The equation that shows the relationship is y = 6 + x

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

Initial number of pieces = 6

Additional number of pieces per week = 1

The equation that shows the relationship is represented as

Number of pieces = Initial number of pieces + Additional number of pieces per week * Number of weeks

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

Number of pieces = 6 + 1 * Number of weeks

So, we have

Number of pieces = 6 + Number of weeks

Using the representations:

We have

y = 6 + x

The amount of interest Maria owes after 6 month of graduation, if she take a subsidized loan of $5,000 and unsubsidized loan of $4,500 is $508.75.

Therefore, the answer is $509.

Subsidized loan

Here, the time period is considered only after graduation, so time period is 6 months, that is 0.5 year. We know simple interest formula where P is the principal amount, r is annual interest rate and n time period in years.

I = P×r×n

Therefore I₁ =  5000 × 0.055 × 0.5

I₁ = 137.5

Unsubsidized loan

Here the time period is considered from the time the loan taken, so time period is one year of graduation plus 0.5 year, i.e. n = 1.5yrs.

Therefore, I₂ = 4500 × 0.055 × 1.5

I₂ = 371.25

Therefore total interest for both the loan is

I = I₁ + I₂

I = 137.5 + 371.25

I = 508.75

I ≈ $509
