When Margo makes cheese ravioli, she uses both ricotta and mozzarella cheeses to make the filling. She often varies the proporti

Answer:

The result is 2

Step-by-step explanation:

A segment requires at least 2 points for its construction.

In geometry, a line segment refers to a section of a line defined by two unique endpoints, encompassing all points located along the line segment between these endpoints.

2x + 4

To represent 2x + 4, the following is required:

2 positive x-tiles corresponding to 2x.

4 positive unit tiles for the value of 4.

3x + (-1)

To illustrate 3x + (-1), you will need:

3 positive x-tiles to depict 3x.

1 negative unit tile to signify (-1).

Answer:

• The mean will decrease, while the median remains unchanged.

Explanation:

Using asterisks instead of dots, the plot described is as follows:

Minutes spent by Sarah getting ready for school, rounded to the nearest five minutes:

                                                               *                *

                                      *       *                *       *       *

                              *       *       *                *       *       *

5    10   15   20    25    30    35    40    45    50    55    60

                                                               *                *

                                      *       *                *       *       *

              *              *       *       *                *       *       *

5    10   15   20    25    30    35    40    45    50    55    60

We need to observe the impacts on the mean and median in both datasets.

The mean will decrease:

The mean is expected to decrease as including a lower value will lower the overall mean.

The calculation is:

• Mean = Total of values / number of values.

• By incorporating a low value (less than the previous mean), the new mean calculation will yield a lower figure.

The median will remain unchanged:

Initially, the first graph contains 13 dots, making the median the value at the seventh dot, which is 45.

In the second graph, there are 14 dots, thus the median is the average of the seventh and eighth positions, both of which are 45, resulting in an overall median of 45.

Therefore, the mean will decrease while the median stays the same.
