Because the y intercept on the graph is 3
And when x is 1 y is 2.5
9514 1404 393
Answer:
y = (-7/3)x +3
Step-by-step explanation:
The line has a negative slope (eliminating choices B and C) that is steeper than a line with a slope of -1, The only answer choice with a negative slope less than -1 is choice D.
__
The slope is the coefficient of x. It is "rise"/"run". Here, the line goes through grid points (0, 3) and (3, -4), so drops 7 units (rise=-7) for each 3 units to the right (run=3). Then the slope is rise/run = -7/3.
The line crosses the y-axis at y=3, so the slope-intercept equation is ...
y = mx + b . . . . . . . . slope = m; y-intercept = b
y = (-7/3)x +3

How do you compute term life insurance?
Answers
1. Add up your assets
Find the sum of your post-tax income and any liquid assets, like life insurance policies you already own, current investments, and future assets like social security benefits.
2. Add up your debts and financial obligations
Account for your yearly living expenses and debt payments and multiply them by the number of years your family would need support. Make sure to include future financial obligations, like college tuition.
3. Subtract your assets from your debts and financial obligations
The resulting number is the coverage gap — the amount of money your family would need to be financially comfortable in your absence, which is the minimum amount your
death benefit
should be. Your policy’s term (i.e., the amount of time your coverage lasts) should last as long as your family’s financial dependence requires.
The death benefit is paid as a lump sum, but your beneficiaries shouldn’t use it all at once. Much of it can be invested, and the rate of return can provide additional income to make the benefit last longer — but you’ll also want to consider the inflation rate over a 20- or 30-year term.
Work with a financial advisor to decide how to maximize the value of your death benefit and prepare your beneficiaries to take on the financial responsibility of the large payment.

a. The test could be conducted on the mean of one sample or two samples of observations.
Find out that which statement is not related to statistics ?The statement "The test could be conducted on the mean of one sample or two samples of observations" is not related to statistics associated with cross-tabulation.
Cross-tabulation, also known as a contingency table or a crosstab, is a statistical technique used to analyze the relationship between two categorical variables. It is commonly used to examine the association between two variables and determine if there is a significant relationship between them.
Options (b), (c), and (d) are all related to statistics associated with cross-tabulation. The chi-square statistic is commonly used to measure the statistical significance of the observed association. The statement in option (c) correctly highlights that the strength of association is of interest only if it is statistically significant. Option (d) mentions several measures that can be used to quantify the strength of association in cross-tabulation, including the phi correlation coefficient, the contingency coefficient, Cramer's V, and the lambda coefficient.

in a(n) "_______" pie chart, each slice is slightly separated from the whole.
Answers
The main answer is: Exploded pie chart.
In an exploded pie chart, each slice is slightly separated or "exploded" from the whole chart.
This separation is achieved by pulling one or more slices away from the center of the pie chart, creating a visual effect of detachment or emphasis on certain categories.
The purpose of using an exploded pie chart is to highlight specific data points or categories in the chart. By pulling out one or more slices, it draws attention to those particular segments and makes them more visually prominent compared to the rest of the chart.
The degree of separation or explosion can vary depending on the design and intent of the chart. Some slices may be slightly pulled out, while others can be significantly detached to create a more pronounced effect. The separation is typically uniform across all slices to maintain visual consistency.

let A^2 = A. prove that either A is singular or det(A)=1
Answers
Eeither A is singular or det(A) = 1.
Let A be a square matrix such that A^2 = A.
If A is singular, then det(A) = 0, and we are done.
Otherwise, let B = A(I - A). Then we have:
B^2 = A(I - A)A(I - A) = A^2(I - A)^2 = A(I - A) = B
Multiplying both sides by B^-1 (which exists since B is invertible), we get:
B^-1 B^2 = B^-1 B
I = B^-1
Now we have:
det(A) = det(B)/det(I - A)
Since B = A(I - A), we have:
det(B) = det(A)det(I - A) = det(A)(1 - det(A))
Substituting into our expression for det(A), we get:
det(A) = det(A)(1 - det(A))/(1 - det(A))
Simplifying, we get:
1 = det(A)
Therefore, either A is singular or det(A) = 1.

Step-by-step explanation:
We want to isolate for x, meaning x must be the only variable on one side of the equationSimplifying an equation would mean to write it in its simplest form which in this case would be when x is by itself.Calculations:
\(3x +4y -4y=16-4y\) - Subtract 4y from both sides to get rid of it on one side.
\(3x=16-4y\) - Simplify the equation.

The given condition can be modeled by the compound inequality:
x < -3 or x > 3.
Which inequality describes the condition?
We want to find an inequality that describes the next condition:
"All real numbers X with an absolute value of greater than three"
So our variable will be X, and the absolute value of X is written as:
|X|
We want to have an absolute value larger than 3, so we can write the inequality:
|X| > 3.
The absolute value part can be separated into two, such that we will get two inequalities:
x > 3
x < -3
So the inequality that illustrates the given condition is the compound inequality:

What are an experiment and observational study?
In observational research, participants are measured or surveyed without any attempt to influence them. In a controlled experiment, participants or objects are divided into groups, and one group is given treatment while the other is not.
What are randomized or block designs?
An experimental design known as a randomized block design divides the experimental units into units known as blocks. The experimental units inside each block are assigned the treatments at random. We have a fully randomised block design when each block has at least one instance of each treatment.
a. Is this an experiment or an observational study?

Answers
The independent variable is the variable you change in an experiment. Therefore, option B is the correct answer.
What is the independent variable?
The experiment's independent variable is defined as the variable that is purposefully modified or controlled. It is the variable being studied during a study to determine how it affects the dependent variable. The dependent variable, on the other hand, is the variable that is being measured or observed in response to the changes made to the independent variable.
The purpose of an experiment is to test a hypothesis. A hypothesis is a statement that predicts an outcome based on some assumptions. The researcher manipulates the independent variable and observes the effect on the dependent variable to test a hypothesis. The hypothesis is supported if changes in the independent variable produce changes in the dependent variable. The theory is rejected if changes in the independent variable do not result in changes in the dependent variable.
Therefore, option B is the correct answer.

Maya just turned 14 years old. Her parents started saving $350 each month for her college.
education when she was born. Her parents want to make sure there will be enough money in
her account by the time she turns 18 to cover tuition and expenses at an in-state, four-year
college. How much will Maya's parents need to raise their monthly contribution for the next 4
years if they want to save at least $80,000?
Answers
Answer:
$91.66
Step-by-step explanation:
We need to calculate how much they've saved so far. So we multiply 12 * 14 to get 168 months (14 years). Then we can multiply 350 by 168 to get $58,800.
We then subtract 58,800 from 80,000 to get 21,200 left to cover over 4 years. In 4 years, there are 48 months so we just divide 21,200 by 48 to get 441.66.
Subtract 350 from 441.66 to get 91.66.
We can check this by doing (350*168) + (441.66 * 48).
Hope this helps,
As always, correct me if I'm wrong
Answer:
Given :-
Money saved by her parents each month = $350
Time = 14 years = 14 × 12 = 168 months
To find :-
How much money ger parents have to save in next 4 years to achieve the goal of $80,000
Total money saved in 14 years = 350 × 168 = $58,800
Total money left to achieve goal = 80,000 - 58,800
= $21,200
Money they have saved next 4 years in each month to achieve the goal
\( = \frac{21200}{4 \times 12} \\ = \frac{21200}{48} \\ = 441.69 \)
They need $441.69 each month to complete $80,000 for her college.
