c)5y = 10 - 2y ⇒ Add 2y to both sides.
d)5 = 25y ⇒ Divide both sides by 25
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
a)2 + 2y = y
to solve the equation in least number of steps, we need to Subtract 2y on both sides.
2+2y-2y=y-2y
2=-y
b)5(y - 4 ) = 2y
to solve the equation in least number of steps, we need to Distribute 5
5y - 40 =2y
c)5y = 10 - 2y
to solve the equation in least number of steps, we need to Add 2y to both sides.

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?
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.

every year a laptop is worth 1/3 of what it was worth for each year previous. if you have a $600 laptop, how much is it worth after 15 years?
The laptop will be worth $0.001286 after 15 years if its worth becomes 1/3 each year.
We can solve this problem by using the formula for geometric sequences,
an = a₁r^(n-1), here in this case, an is the worth of the laptop after n years, r is the rate at which the worth is changing that 1/3 in this case and a₁ is the value of the laptop currently. Substituting the given values, we get:
a₁₅ = 600(1/3)¹⁵⁻¹
a₁₅ = 600(1/3)¹⁴
a₁₅ = 600x0.0000021433
a₁₅ = 0.001286
Therefore, after 15 years, the laptop is worth approximately $0.001286.

k = −3
k = −2
k = 2
k = 3
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.

Se asume que las ventas de un determinado distribuidor de electrodomésticos se aproxima mediante una función lineal. Supongamos que las ventas fueron $5000 en 1982 y de $90,000 en 1987. Si x = 0 representa 1982. Encuentra la ecuación que da las ventas anuales
The equation that gives the annual sales is y = 17,000x - 23,000, where x is the year and x = 0 corresponds to 1982.
What is the slope?In mathematics, slope refers to the steepness or incline of a line on a graph. It is a measure of how much the dependent variable changes for every unit change in the independent variable.
Assuming that the sales of a certain appliance distributor are approximated by a linear function, we can find the equation that gives the annual sales based on the given information.
Let's first find the slope of the line, which represents the rate of change in sales per year. We can use the formula:
slope = (change in y) / (change in x)
where y represents sales and x represents the year, with x = 0 corresponding to 1982.
So, the change in y is 90,000 - 5,000 = 85,000, and the change in x is 1987 - 1982 = 5. Therefore, the slope is:
slope = (change in y) / (change in x) = 85,000 / 5 = 17,000
Now, we can use the point-slope form of the equation of a line, which is:
y - y₁ = m(x - x₁)
where m is the slope, and (x₁, y₁) is a point on the line. We can use either of the given points (1982, 5,000) or (1987, 90,000) as the point on the line. Let's use (1982, 5,000):
y - 5,000 = 17,000(x - 1982)
Simplifying and rearranging, we get:
y = 17,000x - 23,000
Therefore, the equation that gives the annual sales is y = 17,000x - 23,000, where x is the year and x = 0 correspond to 1982.

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

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

The 95% confidence interval for the proportion of all Californians who considered moving out of state is (0.504, 0.530). We can be 95% confident that the true proportion of all Californians who considered moving out of state lies between 50.4% and 53.0%.
The UC Berkeley Institute of Governmental Studies conducted a poll in 2019 with 4,527 respondents in California, where 51.7% of them reported considering moving out of the state. The objective is to calculate a 95% confidence interval for the proportion of all Californians who considered moving out of state, given the sample size and proportion.
B. The formula to calculate the confidence interval for a proportion is:
CI = p^ ± z* √[(p^(1-p^))/n]
Where p^ is the sample proportion, n is the sample size, and z* is the critical value of the standard normal distribution for the desired confidence level. For a 95% confidence level, z* = 1.96.
Substituting the given values into the formula, we get:
CI = 0.517 ± 1.96 * √[(0.517*(1-0.517))/4527]
CI = 0.517 ± 0.013
The 95% confidence interval for the proportion of all Californians who considered moving out of state is (0.504, 0.530). Therefore, we can be 95% confident that the true proportion of all Californians who considered moving out of state lies between 50.4% and 53.0%.
