Answer: The true statements are:-

There are about the same number of points above the x-axis as below it.

The points are randomly scattered with no clear pattern.

The number of points is equal to those in the scatter plot.

Explanation:

  • A residual plot is a graph which shows that the residuals on the vertical axis and the independent variable on the horizontal axis.

Thus, the number of points is equal to those in the scatter plot and ame number of points above the x-axis as below it.

We know the points are randomly scattered across the plot, so that there is no relationship.  Thus the points are randomly scattered with no clear pattern.

Answer:

The statements that best describes a residual plot for a line of best fit that is a good model for a scatter plot is:

  • There are about the same number of points above the x-axis as below it.
  • The points are randomly scattered with no clear pattern.
  • The number of points is equal to those in the scatter plot.

Step-by-step explanation:

We know that a line of best fit is a line that best represents the set of data.

In this the point may or may not lie on the line but the number of points that lie above or below the line are equal ; otherwise the line will not be a line of best fit.

Also the points may be distorted in any manner not necessarily in  a straight line.

valentina_108 [34]

Step-by-step explanation:

\frac{5}{2}  =  \frac{x - 4}{3}

3 \times \frac{5}{2}  =  \frac{x - 4}{3}

\frac{3}{1}  \times  \frac{5}{2}  =  \frac{x - 4}{3}

cross multiplication

\frac{6 \times 5}{2}  =  \frac{x - 4}{3}

15 =  \frac{x - 4}{3}

15 \times 3 = x - 4

45 + 4 = x

49 = x

The first- and second-year enrollment values for a technical school are shown in the table below: Enrollment at a Technical Scho
lyudmila [28]

Answer:

  • <u><em>The solution to f(x) = s(x) is x = 2012. </em></u>

Explanation:

<u>Rewrite the table and the choices for better understanding:</u>

<em>Enrollment at a Technical School </em>

Year (x)       First Year f(x)      Second Year s(x)

2009                  785                        756

2010                   740                        785

2011                    690                        710

2012                   732                         732

2013                   781                          755

Which of the following statements is true based on the data in the table?

  • The solution to f(x) = s(x) is x = 2012.
  • The solution to f(x) = s(x) is x = 732.
  • The solution to f(x) = s(x) is x = 2011.
  • The solution to f(x) = s(x) is x = 710.

<h2>Solution</h2>

The question requires to find which of the options represents the solution to f(x) = s(x).

That means that you must find the year (value of x) for which the two functions, the enrollment the first year, f(x), and the enrollment the second year s(x), are equal.

The table shows that the values of f(x) and s(x) are equal to 732 (students enrolled) in the year 2012,<em> x = 2012. </em>

Thus, the correct choice is the third one:

  • The solution to f(x) = s(x) is x = 2012.
