Step-by-step explanation:
The area of the yard on its own without the small part is 4444 square feet. The right extended part is 9 feet because we can see that it extends a bit farther than the other side parallel to it. 59.5-59.5=9. the small slant would be 12 feet. Now we solve the area of a triangle, the small part, as bh/2. 12*9/2=54. Now we add 54 to 4444 and get 4498.

2. The Line of Best Fit Include your scatter plot and the answers to the following questions in your word processing document:
Which variable did you plot on the x-axis, and which variable did you plot on the y-axis? Explain why you assigned the variables in that way.
Write the equation of the line of best fit using the slope-intercept formula y = mx + b. Show all your work, including the points used to determine the slope and how the equation was determined.
What does the slope of the line represent within the context of your graph? What does the y-intercept represent?
Test the residuals of two other points to determine how well the line of best fit models the data. Use the line of best fit to help you to describe the data correlation.
Using the line of best fit that you found in 2, approximate how tall is a person whose arm span is 66 inches?
According to your line of best fit, what is the arm span of a 74-inch-tall person?
Answers
Answer:
Here's what I get.
Step-by-step explanation:
1. Representation of data
I used Excel to create a scatterplot of the data, draw the line of best fit, and print the regression equation.
2. Line of best fit
(a) Variables
I chose arm span as the dependent variable (y-axis) and height as the independent variable (x-axis).
It seems to me that arm span depends on your height rather than the other way around.
(b) Regression equation
The calculation is easy but tedious, so I asked Excel to do it.
For the equation y = ax + b, the formulas are
\(a = \dfrac{\sum y \sum x^{2} - \sum x \sumxy}{n\sum x^{2}- \left (\sum x\right )^{2}}\\\\b = \dfrac{n\sumx y - \sum x \sumxy}{n\sum x^{2}- \left (\sum x\right )^{2}}\)
This gave the regression equation:
y = 1.0595x - 4.1524
(c) Interpretation
The line shows how arm span depends on height.
The slope of the line says that arm span increases about 6 % faster than height.
The y-intercept is -4. If your height is zero, your arm length is -4 in (both are impossible).
(d) Residuals
\(\begin{array}{cccr}&\textbf{Arm Span} & \textbf{Arm Span}&\\\textbf{Height/in} &\textbf{Actual} & \textbf{Predicted}&\textbf{Residual}\\25 & 19 & 22.3 & -3.3\\40 & 41 & 38.2 & 2.8\\55 & 51 & 54.1 & -3.1\\65 & 67 & 62.6 & 4.4\\ \end{array}\)
The residuals appear to be evenly distributed above and below the predicted values.
A graph of all the residuals confirms this observation.
The equation usually predicts arm span to within 4 in.
(e) Predictions
(i) Height of person with 66 in arm span
\(\begin{array}{rcl}y& = & 1.0595x - 4.1524\\66 & = & 1.0595x - 4.1524\\70.1524 & = & 1.0595x\\x & = & \dfrac{70.1524}{1.0595}\\\\& = & \textbf{66 in}\\\end{array}\\\text{A person with an arm span of 66 in should have a height of about $\large \boxed{\textbf{66 in}}$}\)
(ii) Arm span of 74 in tall person
\(\begin{array}{rcl}y& = & 1.0595x - 4.1524\\& = & 1.0595\times74 - 4.1524\\& = & 78.4030 - 4.1524\\& = & \textbf{74 in}\\\end{array}\\\text{ A person who is 74 in tall should have an arm span of $\large \boxed{\textbf{74 in}}$}\)

Answers
The answers is: 33
33 is the integer that represents her location relative to the surface after 7 seconds.
And 33 feet far the diver have to go to return to the surface.
Step-by-step explanation:
Given:
A scuba diver is 15.5 feet below the surface of the water.
The diver continues to swim downward at a rate of 2.5 feet per second.
Now, to find the integer represents her location relative to the surface after 7 seconds.
And to find how far does the diver have to go to return to the surface.
So, to get the integer represents her location relative to the surface after 7 seconds.
Initial depth = 15.5 feet.
Distance traveled down = 7 × 2.5 = 17.5 feet.
Final depth of water surface = Initial depth + Distance traveled down.
Final depth of water surface = 15.5 feet + 17.5 feet.
Final depth of water surface = 33 feet.
Thus, 33 is the integer represents her location relative to the surface after 7 seconds.
Now, to get how far does the diver have to go to return to the surface:
As, the diver goes to 33 feet down to the surface.
Thus, the diver to return she have to go through the same distance.
So, to return to the surface she need to go to 33 feet far.
Therefore, 33 is the integer that represents her location relative to the surface after 7 seconds.
And 33 feet far the diver have to go to return to the surface.

Reena has a square office with an area of 126 square feet. Jazmine has a square office with an area that is 50% greater than the area of Reena’s office. To the nearest tenth, how much greater is the side length of Jazmine’s office than the side length of Reena’s office?
Answers
Answer:
Reena has a square office with an area of 126 square feet. Jazmine has a square office with an area that is 50% greater than the area of Reena’s office. To the nearest tenth, how much greater is the side length of Jazmine’s office than the side length of Reena’s office?
To find the side length of Jazmine's office, we need to first determine the area of her office. We know that her office has an area that is 50% greater than Reena's office, which means the area of Jazmine's office can be calculated as follows:
Area of Jazmine's office = (1 + 0.5) * Area of Reena's office Area of Jazmine's office = 1.5 * 126 square feet Area of Jazmine's office = 189 square feet
Since Jazmine's office is also square, we can find the side length by taking the square root of the area:
Side length of Jazmine's office = sqrt(189) feet Side length of Jazmine's office ≈ 13.7 feet
To find how much greater the side length of Jazmine's office is than the side length of Reena's office, we simply subtract the side length of Reena's office (which is also the square root of her office's area) from the side length of Jazmine's office:
Side length difference = Side length of Jazmine's office - Side length of Reena's office Side length difference = sqrt(189) feet - sqrt(126) feet Side length difference ≈ 1.8 feet
Therefore, to the nearest tenth, the side length of Jazmine's office is 1.8 feet greater than the side length of Reena's office.
