Barry used a number line to simplify a numerical expression on a math test. Which number did Barry add to get a result of 4 on the numerical expression he simplified? –14 −6 4 14

Answers

Answer 1

To get a result of 4 on the numerical expression, Barry added 4 to the expression on the number line. So, the correct answer is C).

The expression involves adding up the values at different points on the number line. We can see that the value at the point labeled "x" is the missing value that needs to be found.

By adding up the values at each point, we get the following equation

-5 + (-3) + x - (-7) = 1

Simplifying this equation gives

-5 - 3 + x + 7 = 1

Simplifying further

-x = -4

Solving for x, we get

x = 4

Therefore, the value of x that Barry added to the expression on the number line to get a result of 4 is 4. So, the correct option is C).

Many types of bias exist when it comes to surveys, including nonresponse bias, undercoverage, and poorly worded survey questions. Think about a survey you’ve been asked to participate in. Maybe it was printed on a fast-food receipt or a store directed you to an online survey after you made a purchase. What influenced you to participate in the survey or to opt out of participating?

Answers

Answer:

your experience and whether or not you believe any biases were present in the survey.

When it comes to surveys, there are several factors that can influence a person's decision to participate, such as the timing and location of the survey, the perceived relevance of the questions and incentives offered for participation. In some cases, people may opt-out of participating in a survey due to privacy concerns, lack of interest or distrust of the organization conducting the survey.

In terms of biases, survey designers should be careful of different types of biases that can affect the results, such as sampling bias, selection bias and response bias. For example, if a survey is only given to certain demographics, the results may not be representative of the target audience. Similarly, if the survey questions are worded in a leading or biased way, it can influence a person's response and skew the results.

It is important for survey designers to be aware of these biases and take steps to minimize their impact. This can include using random sampling techniques to ensure a representative sample, testing survey questions with focus groups to ensure they are clear and unbiased, and providing clear and transparent information about the purpose and use of the survey data. By taking these steps, survey designers can create surveys that produce accurate and reliable results.

Answer:

People may be more likely to participate in a survey if:

1. They have a positive experience with the company or organization.

2. The survey is relevant to them and they feel their opinion is important.

3. There is some incentive, such as a discount or chance to win a prize.

4. The survey is short and easy to complete.

On the other hand, people may choose to opt-out of a survey if:

1. They don't have the time or interest in participating.

2. They don't trust the company or organization.

3. They don't want to share personal information.

4. The survey is too long or difficult to complete.

It's important for researchers to be aware of these factors to minimize bias in survey results.

Step-by-step explanation:

The graph shows f(x). The absolute value function g(x) is described in the table.

4 6

If g(x) = f(x) + k, what is the value of k?
k = −3
k = −2
k = 2
k = 3

Answers

The value of k, in the absolute function g(x) = f(x) + k is 3.

The correct option is k = 3.

The vertex of the graph of f(x) is at (0, -1).

This means that f(0) = -1.

To make g(x) = f(x) + k, we need to add k to every y-value of the graph of f(x).

Since f(0) = -1, we want g(0) = f(0) + k = -1 + k.

Looking at the table of values for g(x), we see that g(0) = 2.

Therefore, we have:

-1 + k = 2

Solving for k, we get:

A system of linear equations for line h and j are y = -3x/4 - 5 and y = -5x/4 + 1 respectively.

An equation for the exponential function graphed is [tex]f(x)=\frac{1}{3}^{x}[/tex]

How to determine an equation of lines h and j?

First of all, we would determine the slope of line h as follows;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (1 - 7)/(-8 + 16)

Slope (m) = -6/8

Slope (m) of line h = -3/4.

At data point (-8, 1) and a slope of -3/4, a linear equation in slope-intercept form for line h can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y - 1 = -3/4(x + 8)

y - 1 = -3x/4 - 6

y = -3x/4 - 5

At data point (-4, 6) and a slope of -5/4, a linear equation in slope-intercept form for line j can be calculated by using the point-slope form as follows:

y - 6 = -5/4(x + 4)

y - 6 = -5x/4 - 5

y = -5x/4 + 1

In Mathematics, an exponential function can be modeled by using the following mathematical equation:

[tex]f(x) = a(b)^x[/tex]

Since this exponential function passes through the points (0, 1) and (-1, 3), we have:

1 = ab⁰

1 = a

3 = a(b)⁻¹

3 = 1 × (b)⁻¹

3 = 1/b

b = 1/3

Therefore, the graphed exponential function is given by;

[tex]f(x) = a(b)^x\\\\f(x) = 3^{-x}\\\\f(x)=\frac{1}{3}^{x}[/tex]

A large business took in 7 million dollars in insurance premiums and paid out 5.9 million in medical claims. Did this business meet the minimum MLR?

Answers

Answer:

Step-by-step explanation:

To determine if the business met the minimum Medical Loss Ratio (MLR), we need to calculate the MLR for this business. The MLR is the ratio of the total amount of premiums received by the insurance company to the total amount of premiums spent on medical claims. The Affordable Care Act (ACA) requires insurance companies to meet a minimum MLR of 80% in the individual and small group markets, and 85% in the large group market.

Given that the business took in 7 million dollars in insurance premiums and paid out 5.9 million in medical claims, we can calculate the MLR as follows:

MLR = Total premiums spent on medical claims / Total premiums received

MLR = 5.9 million / 7 million

MLR = 0.8428571428571429 or 84.29%

Since the MLR for this business is 84.29%, which is higher than the minimum MLR required by the ACA for the large group market (85%), we can conclude that the business did not meet the minimum MLR.

What is transposition-method?

Using the Transposition Method, one variable linear equations can be solved. There are situations when an equation's two sides have both constants and variables. In these situations, we first simplify the two sides into their simplest forms before transposing phrases containing variable on the RHS to the LHS and constant terms on the LHS to the RHS.

Given equations are:

2 + 2y = y

5(y - 4 ) = 2y

5y = 10 - 2y

5 = 25y

Volume is a measure of the amount of space occupied by a three-dimensional object or substance. It is typically measured in cubic units such as cubic meters (m³) or cubic feet (ft³). The volume of an object can be calculated by multiplying its length, width, and height (or depth) together, or by using a specific formula depending on the shape of the object.

To find the total volume of Tank A, we need to add the volumes of the two sections.

The volume of the first section is 24 cubic feet.

a frog swims 8 miles downstream in 2 hours. she returns upstream in 14 hours. how fast does the frog swim in still water?

Answers

The frog's speed in still water is 2.2857 miles per hour.

Let's call the frog's speed in still water "s", and the speed of the current "c".

When the frog is swimming downstream, its effective speed is the sum of its speed in still water and the speed of the current. So the distance it covers in 2 hours is:

distance = speed x time

8 = (s + c) x 2

Simplifying this equation, we get:

s + c = 4

When the frog is swimming upstream, its effective speed is the difference between its speed in still water and the speed of the current. So the distance it covers in 14 hours is:

distance = speed x time

8 = (s - c) x 14

Simplifying this equation, we get:

s - c = 0.5714

Now we have two equations with two unknowns:

s + c = 4

s - c = 0.5714

We can solve for s (the frog's speed in still water) by adding these two equations:

2s = 4.5714

Brandon estimated that he would spend $35 on his ticket and snacks at a baseball game with his friends. Happily, he only spent $28. What is the percent error for Brandon's estimate?

Answers

Answer:

25%

Step-by-step explanation:

The percent error can be calculated using the formula:

(percent error) = [(|estimated value - actual value|) / actual value] x 100%

In this case, the estimated value is $35, and the actual value is $28. Therefore:

(percent error) = [(|35 - 28|) / 28] x 100%

(percent error) = (7 / 28) x 100%

(percent error) = 0.25 x 100%

(percent error) = 25%

Therefore, Brandon's estimate had a percent error of 25%.

through a 120° angle as its rubber blade cleans the windshield. The wiper blade begins
cleaning at a distance of 4 inches from the point of rotation. The wiper blade is 16 inches
long.
4 in.
16 in.
What is the area cleaned by the wiper blade?

Answers

The area cleaned by the wiper blade is 418.88 square inches.

How to solve

The area purged by the cleaning mechanism can be determined to possess the features of a fractional sector of a circular shape, with the circumference comprising of the addition of the longitudinal length and layer height of the wiper blade (20 inches total).

This yields a calculation of Area = (120°/360°) * π * (20 in)^2 = (1/3) * π * 400 in^2 ≈ 418.88 square inches.

The surface area is the amount of space that is covering the external parts of an object. It is a two-dimensional quantity used to quantify the outermost dimension of something.
