The multiple coefficients of determination, R², is 0.7, or 70% evaluated using the formula R² = SSR/SST.
The numerous coefficient of assurance called R-squared (R²), may be a degree of the extent of the full variety within the subordinate variable clarified by the free factors within the relapse demonstrate.
To calculate R² you can use the following formula:
R² = SSR/SST
where:
SSR is the regression sum of squares.
SST is the sum of squares. This is the regression sum of squares plus the error sum of squares.
In this case SSR = 1400 and SSE = 600. SST can be calculated as:
SST = SSR + SSE
= 1400 + 600
= 2000
Therefore, R² is
R² = SSR/SST
= 1400 / 2000
= 0.7
Therefore, the fold determination coefficient R² is 0.7 or 70%.

Mr. Snowdon posted the final exam grades for Algebra II in the hallway as soon as the tests were graded. The data is represented on the box plot below.
Which set of data below represents the interquartile range and the maximum, in that order?
The set of data that represents the interquartile range and the maximum, in that order, is (80 - 70, 95), which simplifies to (10, 95).
Looking at the box plot, we can see that the box spans from approximately 65 to 85, with the median at around 75. To find the values for the interquartile range and maximum, we need to determine the exact values for Q1, Q3, and any outliers.
From the box plot, we can estimate that Q1 is around 70 and Q3 is around 80.
The median of the lower half of the data is the middle value between the smallest value and the median, which is approximately 68.
The median of the upper half of the data is the middle value between the median and the largest value, which is approximately 83.
To find the maximum value, we look for the highest data point that is not an outlier. From the box plot, we can see that there are no outliers, so the maximum value is the highest value in the data set, which is approximately 95.
Therefore, the set of data that represents the interquartile range and the maximum, in that order, is (80 - 70, 95), which simplifies to (10, 95).

If the function's f(x) = |x|, graph is shifted right by 3 units, and vertically stretched by a factor of "4", then function which best describes the transformed-function is 4|x-3|.
Let the transformed function be : g(x); The transformed function g(x) is obtained by applying two transformations to the original function f(x) = |x|.
The "first-transformation" is to make a "horizontal-shift" (right-shift) of 3 units. This means that the entire graph of the function is shifted to the right by 3 units, so, function becomes |x-3|.
The "second-trans-formation" is to stretch the graph vertically by a factor of 4. This means that the entire graph of the function is stretched vertically,
Now, the function becomes, g(x) = 4|x-3|.

narrator that's right! there needs to be motivation to change for employees. so what can you ask the vp and analyst in the unfreezing stage in order to influence change? should we survey a sample set of employees at each of our locations to ask what they dislike about the current system? should we survey a sample set of employees at each of our locations to ask their opinions on whether we should change systems or not? should we mandate change now? should we even be changing?
It's crucial to take a collaborative approach and involve employees in the change process as much as possible.
In the unfreezing stage, it is important to gather information and input from various stakeholders in order to influence change effectively. Therefore, asking the VP and analyst questions such as "What do you think are the areas that need improvement in our current system?" or "How do you think changing the system would benefit our organization?" can provide valuable insight into the motivation for change.
Surveying a sample set of employees at each location to ask their opinions on the current system and whether they think changes are necessary is also a good approach. This can help to identify common pain points and gauge the level of employee buy-in for potential changes. It's important to also consider other factors such as the cost and feasibility of implementing changes, as well as potential risks and benefits.
Mandating change without proper analysis and buy-in from employees may lead to resistance and resentment. Ultimately, the decision to change or not should be based on a thorough assessment of the situation, including feedback from stakeholders and the potential impact on the organization.

Therefore, the image coordinates of the vertices of triangle N'M'O' are: N'(-11, -2), M'(-8, -1), O'(-11, -5) that is option D.
What is coordinate?In mathematics, a coordinate is a numerical value that specifies the position of a point in a geometric space, relative to a reference frame or origin. Coordinates are commonly used to describe the position of points in two-dimensional (2D) or three-dimensional (3D) space. In 2D space, a point can be described by its x-coordinate and y-coordinate. The x-coordinate represents the horizontal distance of the point from the origin, while the y-coordinate represents the vertical distance of the point from the origin. Together, the x-coordinate and y-coordinate specify the position of the point in the 2D space. In 3D space, a point can be described by its x-coordinate, y-coordinate, and z-coordinate. The x-coordinate represents the horizontal distance of the point from the origin, the y-coordinate represents the vertical distance of the point from the origin, and the z-coordinate represents the distance of the point along the depth or height axis. Together, the x-coordinate, y-coordinate, and z-coordinate specify the position of the point in the 3D space.
Here,
To determine the image coordinates of N'M'O' after translating the preimage 7 units to the left, we need to subtract 7 from the x-coordinates of each point.
The coordinates of N', M', and O' are obtained by subtracting 7 from the x-coordinates of N, M, and O respectively:
N' = (-4 - 7, -2) = (-11, -2)
M' = (-1 - 7, -1) = (-8, -1)
O' = (-4 - 7, -5) = (-11, -5)
Therefore, the image coordinates of N'M'O' are ON'(-11, -2), M'(-8, -1), O' (-11,-5). Answer option (D) is correct.

The amount of money Morgan will have after 3 years in the savings account is $315.60.
The formula to calculate the amount of money in a savings account after a certain number of years with compound interest is
A = P(1 + r/n)^(nt)
Where:
A = the amount of money in the account after the specified time period
P = the principal amount (initial investment)
r = the annual interest rate (as a decimal)
n = the number of times the interest is compounded per year
t = the number of years
In this case, Morgan invests $275 at an interest rate of 4% per year, compounded once a year, and keeps the money in the account for 3 years.
So, we can plug in the values into the formula
A = 275(1 + 0.04/1)³
A = 275(1 + 0.04)³

Solve the system of equations. 4x – y = 4 2x2 – y = 4
Answer:
-4 or 4
Step-by-step explanation:
We can solve for the value of y by using the first equation to express y in terms of x and then substituting the resulting expression for y into the second equation.
From the first equation, we have:
4x - y = 4
Rearranging this equation to solve for y, we get:
y = 4x - 4
Now, we can substitute this expression for y into the second equation:
2x^2 - y = 4
Replacing y with 4x - 4, we get:
2x^2 - (4x - 4) = 4
Expanding the brackets and simplifying, we get:
2x^2 - 4x + 4 = 4
Subtracting 4 from both sides, we get:
2x^2 - 4x = 0
Factorizing, we get:
2x(x - 2) = 0
Using the zero product property, we see that this equation is satisfied when either 2x = 0 or x - 2 = 0.
If 2x = 0, then x = 0, and we can use the expression for y that we found earlier to get:
y = 4x - 4 = 4(0) - 4 = -4
If x - 2 = 0, then x = 2, and again using the expression for y, we get:
y = 4x - 4 = 4(2) - 4 = 4
Therefore, the possible values of y are -4 and 4. We would need more information to determine which value of y is the correct one in this context.
Midland Electronics is advertising that everything in their store is 10% off. If p represents the original price of an item in
their store, then the sale price of the item can be represented by the expression p - 0.1p.
A. Write an equivalent expression to represent the sale price of the item.
B. Using complete sentences, describe how the sale price can be found in two different ways.
Results:
A. An equivalent expression to represent the sale price of the item of p - 0.1p = 0.9p.
B. The different ways to be used to find the sale price of an item in Midland Electronics are:
(i) We can take the original price of the item and multiply it by 0.9, which is the percentage of the original price that is being paid after the 10% discount.
(ii) Or we can subtract the discount amount from the original price, where the discount amount is equal to 0.1 times the original price.
Both of these methods lead to the same sale price of the item.
How to write an equivalent expression to represent the sale price of the item?We can write the expression by:
Simplify the expression p - 0.1p by factoring out the common factor of p:
p - 0.1p = p(1 - 0.1)
Simplifying further, we can see that 1 - 0.1 equals 0.9
Substitute the value back into the expression:
p - 0.1p = p(1 - 0.1)
= p(0.9) = 0.9p
Thus, an equivalent expression of p - 0.1p = 0.9p

Answer: B. $1.49
Step-by-step explanation:
1.) Find how much one pound of cherry tomatoes would cost. To do so, do
4.50 (the cost for 3 lbs for cherry tomatoes) /3 (the number of pounds), which would be $1.50 per pound of cherry tomatoes.
2.) Find how much one pound of heirloom tomatoes would cost. To do so, do 5.98 (the cost for 2 pounds for heirloom tomatoes) /2 (the number of pounds), which would be $2.99 per pound of heirloom tomatoes.
3.) Subtract. To find the "difference" in the unit costs of the tomatoes, do 2.99-1.50=1.49.
Therefore, the difference in the unit costs of the tomatoes is B. $1.49.

The possible values of x are numbers greater than 2, that is x > 2. The square have a greater area than the rectangle, and the difference in areas is 1 cm²
How to evaluate for x of the rectangle and squareAll values equal to or less than 2 will result to either negative or a zero for the width of the rectangle, thus only numbers greater than 2 can give positive side lengths so possible values of x > 2.
If x = 3 then;
Area of rectangle = 3 cm × (3 - 2) cm
Area of rectangle = 3 cm²
Area of square = (3 - 1)cm × (3 - 1) cm
Area of square = 2 cm × 2 cm
Area of square = 4 cm²
For any value of x greater 2, the difference in the areas is 1 cm²

Graph f(x) = -2/3x -3
Use the line tool and select two points to graph the line.
Answer:
(0, -3) and (3, -5)
Step-by-step explanation:
To graph the line of the equation f(x) = -2/3x - 3, we can choose any two points on the line. One way to do this is to find the y-intercept and another point using the slope of the line.
1. To find the y-intercept, let x = 0 and solve for y:
f(0) = -2/3(0) - 3 = -3
So the y-intercept is (0, -3).
2. To find another point, we can use the slope of the line, which is -2/3. We can start from the y-intercept (0, -3) and move down 2 units (since the slope is negative) and to the right 3 units (since the denominator of the slope is 3) to get another point on the line:
(3, -5)
So the two points we can use to graph the line are (0, -3) and (3, -5).

A jelly bean is selected at random from a jar and is not returned. The jar contains 8 red, 2 green, 4 blue, and 7 pink jelly beans. Which is the probability of selecting a red jelly bean the first draw and a blue jelly bean on the second draw?
(A) 4/7
(B) 1/70
(C) 8/105
(D) 32/441
8/105 is the probability of selecting a red jelly bean the first draw and a blue jelly bean on the second draw, Therefore option C is correct.
The probability of selecting a red jelly bean on the primary draw is 8/(8+2+4+7) = 8/21, for the reason that there are 8 red jelly beans out of a complete of 8+2+4+7 = 21 jelly beans.
Since the jelly bean is not returned to the jar after the first draw, the number of jelly beans in the jar decreases through 1. consequently, on the second draw, there are 20 jelly beans left within the jar.
Out of those 20 jelly beans, 4 are blue. for that reason, the possibility of selecting a blue jelly bean on the second one draw, given that a red jelly bean was selected on the first draw, is 4/20 = 1/5.
To discover the probability of both events going on collectively & we multiply the probabilities of the 2 events:
P(red on 1st and Blue on 2d) = P(red on 1st) * P(Blue on 2nd | red on 1st)
P(red on 1st and Blue on 2nd) = (8/21) * (1/5)
P(red on 1st and Blue on 2nd) = 8/105
Therefore, 8/105 is the probability of selecting a red jelly bean the first draw and a blue jelly bean on the second draw
