When solving a word problem using a system of equations with two unknowns, you must create two equations. So, correct option is B.

The reason is that each unknown in the problem requires an equation to represent its relationship with the other variables.

For example, let's say you have two unknowns, x and y. You need two equations to define the relationships between these variables. These equations can be represented as:

Equation 1: x + y = 10 (This equation represents the relationship between x and y based on the given information in the problem.)

Equation 2: 2x - y = 4 (This equation represents another relationship between x and y based on additional information provided in the problem.)

With a system of two equations involving two unknowns, you can use algebraic methods such as substitution or elimination to solve for the values of x and y.

Having only one equation would not be enough to determine unique values for both x and y, as there would be an infinite number of possible solutions. On the other hand, having more than two equations might lead to over-determining the system, making it inconsistent or redundant.

Therefore, two equations are the minimum required to solve for two unknowns effectively. So, correct option is B.

The percentage increase is about 16.66%.

What is a percentage increase?

The percentage increase formula is the ratio of value increased to the original value and multiplied by 100. It is expressed in percentage. If there is an increase in the value of anything, then there is an increase in the percentage.

The initial amount was $18 and the final amount is $21.60.

By using the percentage increase formula, we can write

        Percentage increase = (final value - initial value)/|Final value| * 100

                                            = ((21.60 - 18)/21.60)*100

                                            = 16.66%

Hence, the percentage increase is about 16.66%.

Answer:

To create a proportion using the form %/100 = is/of, we can first write the given information in the form %/100 = is/of. In this case, we know that 1 1/2% represents 15, so we can write:

1 1/2%/100 = 15/of

Next, we need to solve for the "of" value, which is the number we are trying to find. To do this, we can multiply both sides of the equation by 100 and then divide both sides by 1 1/2% to get:

(1 1/2%/100) * 100 = (15/of) * 100

of = (15/1 1/2%) * 100

Finally, we can evaluate the right-hand side of the equation to find the value of "of". Since 1 1/2% is the same as 1.5%, we can substitute 1.5 for 1 1/2% in the equation to get:

of = (15/1.5%) * 100

of = (15/0.015) * 100

of = 1000

Therefore, the number we are trying to find is 1000.

In summary, the proportion that represents the given word problem is:

1 1/2%/100 = 15/1000

Answer:

[tex]\textsf{Proportion}: \quad \sf \dfrac{1.5}{100}=\dfrac{15}{x}[/tex]

[tex]\textsf{Solution}: \quad \sf x=1000[/tex]

Step-by-step explanation:

Given proportion formula:

[tex]\sf \dfrac{\%}{100}=\dfrac{is}{of}[/tex]

Given word problem:

Let the unknown number be x.

Therefore:

Substitute these into the proportion formula to create a proportion to represent the given word problem:

[tex]\sf \dfrac{1.5}{100}=\dfrac{15}{x}[/tex]

To solve the proportion, cross multiply:

[tex]\implies \sf 1.5x=15 \cdot 100[/tex]

[tex]\implies \sf 1.5x=1500[/tex]

Divide both sides by 1.5:

[tex]\implies \sf \dfrac{1.5x}{1.5}=\dfrac{1500}{1.5}[/tex]

As a/b times c/d = ac/bd, we can simply extend multiplication to rational integers. By the way, this definition enables us to say that multiplication is closed for rational numbers.

Concentrating on the words "sum" and "product" in relation to "things that aren't numbers" is still beneficial. In logic, the terms "sum" and "product" have a non-numerical sense as the union and intersection of sets.

For instance, a "blue circle" is a reasonable outcome. It is where the "blue" and "circle" sets cross. The only components in the logical combination of the two sets would be those that are "blue" or "circular."

Length of each Plan A workout: 4 hours and Length of each Plan B workout: 8 hours.

To find the length of each workout plan, we need to know the total amount of time that Deshaun spent on each plan. We can find this by adding up the number of clients who did each plan on Friday and Saturday and then multiplying by the total amount of time that Deshaun spent training his clients on each day.

On Friday, Deshaun had 4 clients who did Plan A and 8 who did Plan B, for a total of 4 + 8 = 12 clients.

On Saturday, Deshaun had 2 clients who did Plan A and 3 who did Plan B, for a total of 2 + 3 = 5 clients.

In total, Deshaun had 12 + 5 = 17 clients who did his workout plans.

Since Deshaun trained his Friday clients for a total of 17 hours and his Saturday clients for a total of 7 hours, the total amount of time that he spent on Plan A was 4 × 17 = 68 hours.

The total amount of time that he spent on Plan B was 8 × 17 = 136 hours.

Since there were 17 clients in total, the length of each Plan A workout is 68 / 17 = 4 hours.

The length of each Plan B workout is 136 / 17 = 8 hours.

Thus, the length of each Plan A workout is 4 hours, and the length of each Plan B workout is 8 hours.

1/2 is the slope of the following when you simplify

The correct answer is D. A 95% confidence interval must be wider than an 80% confidence interval in order to be more confident that it captures the true value of the population proportion.

The width of a confidence interval reflects the degree of uncertainty about the estimate of the population parameter. A wider interval indicates a higher degree of uncertainty, while a narrower interval indicates a lower degree of uncertainty.

The confidence level of a confidence interval is the probability that the interval contains the true population parameter. For example, a 95% confidence interval means that there is a 95% probability that the interval contains the true population parameter. Similarly, an 80% confidence interval means that there is an 80% probability that the interval contains the true population parameter

Since a 95% confidence interval is more confident that it captures the true value of the population parameter than an 80% confidence interval, the 95% confidence interval must be wider in order to capture the true value with a higher degree of confidence.

The total charge for taking 30 people aboard = $180

The total charge for taking 50 people on board = $220

The differences in the number of people and charges are 20 and $40, respectively.

Let x = the number of people boarding the bus and n = the fixed rate per bus.

30x + n = 180 ... Equation 1
