Answer:

6 times

Step-by-step explanation:

28claps =12seconds

? = 0.5minutes

60seconds=1minute

? =0.5 minutes

(cross multiply)

60*0.5/1 = ?

?=30seconds

28claps = 12secs

? =30secs

28*30/12 =?

HELP!!!!!!!!!!!
Svetradugi [14.3K]

Using the mean concept, it is found that:

Relative to Sabrina's goal, her average swim time over the last five weeks is 0.1 hours.

-----------------------

The mean of a data-set is given by the <u>sum of all observations divided by the number of observations</u>.

In this problem:

  • The data-set is her swim time relative to her goal, which is: {1.25, -1, 2.25, 0, -2.}
  • 5 observations.

Thus, the mean is:

M = \frac{1.25 - 1 + 2.25 + 0 - 2}{5} = 0.1

Relative to Sabrina's goal, her average swim time over the last five weeks is 0.1 hours.

Hey uh can anyone help me with this? This is a test and I dont need an explanation since its the last day of the marking period,
Archy [21]

Answer:

Look at explanation.

Step-by-step explanation:

<em><u>Dilation of scale factor of 5, because it would become more wide and open by a factor of 5. Reflection over y-axis, because it makes the shape double the size. Dilation of scale factor of 1/2, because it makes the shape half it's size.</u></em> The rotating 90 degrees would only change the shapes position, not the size. The translation would only move the shape to a different area, and not change the size.
