The width of a table is 2 feet less than the length. The area is 20 square feet. Find the dimensions. Show and explain all work using mathematical concepts in this module. (use quadratic equation)
Let's denote the length of the table as "x" feet. According to the problem, the width is 2 feet less than the length, so the width can be represented as "x - 2" feet. The area of the table is given as 20 square feet.
The formula for the area of a rectangle is length times width. Therefore, we can set up the equation:
Length × Width = Area
x(x - 2) = 20
Expanding the equation, we get:
x^2 - 2x = 20
Rearranging the equation in quadratic form:
x^2 - 2x - 20 = 0
To solve this quadratic equation, we can factor it or use the quadratic formula. Let's use the quadratic formula:
x = (-b ± √(b^2 - 4ac)) / (2a)
For our equation, a = 1, b = -2, and c = -20. Plugging these values into the quadratic formula, we get:
x = (-(-2) ± √((-2)^2 - 4(1)(-20))) / (2(1))
Simplifying further:
x = (2 ± √(4 + 80)) / 2
x = (2 ± √84) / 2
x = (2 ± 2√21) / 2
Simplifying the expression inside the square root:
x = (1 ± √21)
So the possible values for x are 1 + √21 and 1 - √21.
Since the length cannot be negative, we take the positive value:
x = 1 + √21
Now we can find the width by substituting this value of x into the expression for width:
Width = x - 2
Width = (1 + √21) - 2
Width = -1 + √21
Therefore, the dimensions of the table are approximately 1 + √21 feet for the length and -1 + √21 feet for the width.

Step-by-step explanation:
Which point is found on the line represented by the equation y+6=x ?
A (−5,1)
B (2,−4)
C (3,9)
D (6,6)
The point that satisfies the equation y+6=x is :
A (−5,1)
The line represented by the equation y+6 = x can be rewritten as x - y = -6. The equation is in the standard form:
Ax + By = C.
The x-intercept and y-intercept can be found using the standard form. Then, plot these points on the graph and draw a straight line between them to complete the graph of the equation.
Using the equation x - y = -6 to find the x-intercept, set y = 0 and solve for x.
Thus, x - 0 = -6x = -6
The x-intercept of the line is (-6, 0).
Using the equation x - y = -6 to find the y-intercept, set x = 0 and solve for y.
Thus, 0 - y = -6y = 6
The y-intercept of the line is (0, 6).
Plot the x-intercept (-6,0) and the y-intercept (0,6) on the coordinate plane. Then, draw the line through these points.
Now, we need to find which point is found on the line represented by the equation y+6 = x.
We can now plug in the values of the points to the equation:
y + 6 = x
x - y = -6(-5) - 1 = -6
The point A (-5,1) satisfies the equation since x - y = -6.
So, the answer is A (−5,1).

What is the measure of the third angle?
Answer:
90
Step-by-step explanation:
Answer:
90 degrees
Step-by-step explanation:
Step One: In order to solve this problem, you need to know that all angles in a triangle add up to 180 degrees.
Step Two: Now that we know that information, we need to add the angles we do know together: 34+56= 90 degrees.
Step Three: We subtract 90 from 180 to figure out the missing angles: 180-90= 90 degrees.
Find slops ;
3y=9x+18
To find the slope of the line, we need to put the equation in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.
Step 1: Divide both sides of the equation by 3 to get y by itself on one side of the equation.
3y = 9x + 18
y = 3x + 6
Step 2: Compare the equation to the slope-intercept form y = mx + b, and we can see that the slope is 3.
Therefore, the slope of the line is 3.

You can practice on this problem. 1. A sample of men agreed to participate in a study to determine the relationship between several variables including height, weight, waste size, and percent body fat. A scatterplot with percent body fat on the y-axis and waist size (in inches) on the horizontal axis revealed a positive linear association between these variables. Computer output for the regression analysis is given below: Dependent variable is: WBE R-squared - 67.8% S - 4.713 with 250-2 - 248 degrees of freedom Variable Constant Waist Coefficient -42.734 1.70 se of coeff 2.717 0.0743 t-ratio -15.7 22.9 prob <.0001 <.0001 (a) Write the equation of the regression line (be sure to use correct notation and define your variables): (b) Explain/interpret the information provided by R-squared in the context of this problem. Be specific, (c) Calculate and interpret the correlation coefficient (r). (d) One of the men who participated in the study had waist size 35 inches and 10% body fat. Calculate the residual associated with the point for this individual.
(a) The equation of the regression line Percent Body Fat = -42.734 + 1.70 * Waist Size
(b) The higher the R-squared value, the better the regression line fits the data and the stronger the relationship between the variables.
(c) It means that as waist size increases, the percentage of body fat also tends to increase, and vice versa.
(d) The residual associated with this point is approximately -6.766
(a) The equation of the regression line can be written as:
Percent Body Fat = -42.734 + 1.70 * Waist Size
In this equation, Percent Body Fat represents the dependent variable, Waist Size represents the independent variable, -42.734 is the intercept (constant), and 1.70 is the coefficient for the Waist Size variable.
(b) R-squared is a measure of how well the regression line fits the data. In this context, R-squared of 67.8% indicates that 67.8% of the variation in the percent body fat can be explained by the linear relationship with waist size. The higher the R-squared value, the better the regression line fits the data and the stronger the relationship between the variables.
(c) To calculate the correlation coefficient (r), we can take the square root of the R-squared value. In this case, the correlation coefficient would be approximately √(0.678) ≈ 0.823.
Interpretation: The correlation coefficient (r) of 0.823 indicates a strong positive linear relationship between waist size and percent body fat. It means that as waist size increases, the percentage of body fat also tends to increase, and vice versa.
(d) To calculate the residual associated with the point for an individual with a waist size of 35 inches and 10% body fat, we need to substitute the waist size value into the regression equation and calculate the difference between the actual percent body fat and the predicted percent body fat.
Using the regression equation: Percent Body Fat = -42.734 + 1.70 * Waist Size
Substituting Waist Size = 35:
Percent Body Fat = -42.734 + 1.70 * 35 = -42.734 + 59.5 ≈ 16.766
The actual percent body fat for this individual is 10%. Therefore, the residual can be calculated as:
Residual = Actual Percent Body Fat - Predicted Percent Body Fat
Residual = 10 - 16.766 ≈ -6.766
The residual associated with this point is approximately -6.766. This indicates that the actual percent body fat is about 6.766 units lower than the predicted value based on the regression equation.

New Mexico is the correct option with coordinates (-2.5,-1).
To find the midpoint between two points in the Cartesian plane, you can use the midpoint formula. The midpoint formula states that the coordinates of the midpoint between two points (x₁, y₁) and (x₂, y₂) are given by:
Midpoint = ((x₁ + x₂) / 2, (y₁ + y₂) / 2).
Here's a step-by-step process to find the midpoint:
1. Identify the coordinates of the two points you want to find the midpoint between. Let's say the coordinates are (x₁, y₁) and (x₂, y₂).
2. Add the x-coordinates of the two points together: x = x₁ + x₂.
3. Divide the sum by 2 to find the x-coordinate of the midpoint: x = x / 2.
4. Add the y-coordinates of the two points together: y = y₁ + y₂.
5. Divide the sum by 2 to find the y-coordinate of the midpoint: y = y / 2.

on a 7 question multiple-choice test, where each question has 4 answers, what would be the probability of getting at least one question wrong?
On a 7-question multiple-choice test, with 4 answer choices for each question, we need to determine the probability of getting at least one question wrong.
To calculate the probability of getting at least one question wrong, we can consider the complementary probability, which is the probability of getting all questions correct and subtract it from 1.
The probability of getting a single question correct is 1/4, since there are 4 answer choices for each question. Therefore, the probability of getting all 7 questions correct is (1/4) * (1/4) * (1/4) * (1/4) * (1/4) * (1/4) * (1/4) = [tex](1/4)^7[/tex].
To find the probability of getting at least one question wrong, we subtract the probability of getting all questions correct from 1:
P(at least one question wrong) = 1 - P(all questions correct).
Substituting the probability of getting all questions correct, we have:
P(at least one question wrong) = 1 - [tex](1/4)^7[/tex]
Calculating this expression, the probability of getting at least one question wrong is approximately 0.99999, which is essentially equal to 1
Therefore, on a 7-question multiple-choice test with 4 answer choices for each question, the probability of getting at least one question wrong is extremely high, nearly 1. This means that it is highly likely that a test taker will get at least one question wrong on such a test.

The number of dandelions at the beginning of the summer was 2,000. The population of dandelions is expected to grow at a rate of 2.5% each day. How many dandelions should we expect after 30 days?
Answer:
3500 dandelions
Step-by-step explanation:
To start you must multiply the number of dandelions by the growth rate to find the number of dandelions grown each day:
2,000 * 0.025 = 50
Then you multiply the number of dandelions by 30 for each day:
50 * 30= 1500
Lastly, you add the dandelions grown in 30 days to the original for your answer.

Frank owns a $141,000 home, for which he has a 30-year mortgage in the
amount of $700 a month. Once he has paid off the mortgage, how much will
he have paid in interest?
A. $111,000
B. $120,000
C. $141,000
D. $109,000
Answer: the answer is A !!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Step-by-step explanation:
After paying off the mortgage, Frank will have accrued interest costs of $111,000 in total. $111,000 is the correct response.
What is compound interest?The interest earned on savings that are computed using both the original principal and the interest accrued over time is known as compound interest. [tex]A = P(1 + r/n)^{nt[/tex], where P is the principal balance, r is the interest rate, n is the number of times interest is compounded annually, and t is the number of years, which is the formula for compound interest.
The total amount paid by Frank over 30 years will be the product of the monthly payment and the number of months in 30 years:
The total amount paid = Monthly payment × Number of months
Total amount paid = $700/month × 12 months/year × 30 years
Total amount paid = $252,000
However, this total amount includes both the principal (the original loan amount of $141,000) and the interest. To find the amount of interest paid, we need to subtract the principal from the total amount:
Interest paid = Total amount paid - Principal
Interest paid = $252,000 - $141,000
Interest paid = $111,000
Therefore, Frank will have paid $111,000 in interest once he has paid off the mortgage. The answer is A. $111,000.

Here, the analyst uses the benchmark returns as the explanatory variable, i.e., the x-variable, to explain the variation of portfolio returns, the y-variable. The analyst performs a regression analysis between the x and y variables. The y-intercept and slope coefficient of the x-variable are 0.013 and .892, respectively. If the benchmark return is 14%, the regression model will estimate the portfolio return closest to O 0% O 89.2% 1.3% O 13.79%
The regression model estimates the portfolio return closest to 13.79% when the benchmark return is 14%.
The analyst performed a regression analysis using the benchmark returns as the explanatory variable and the portfolio returns as the dependent variable. The y-intercept of the regression line is 0.013, indicating that when the benchmark return is zero, the estimated portfolio return is 0.013%. The slope coefficient of the benchmark returns is 0.892, meaning that for every 1% increase in the benchmark return, the estimated portfolio return increases by 0.892%.
To estimate the portfolio return when the benchmark return is 14%, we plug the value of 14 into the regression model. The estimated portfolio return is calculated as follows: 0.013 + 0.892 * 14 = 13.79%.
Therefore, based on the regression analysis, the model estimates that the portfolio return would be closest to 13.79% when the benchmark return is 14%.
