Answer:
34/13
Step-by-step explanation:
The length-to-width ratio here is:
8.5 / 3.25
which can be reduced by dividing numerator and denominator both by 0.25:
8.5/0.25
--------------- = 34/13
3.25/0.25
Answer:

Required
The IQR
This is calculated as:

Calculate 



Remove bracket

This means that:
is the mean of 5th and 6th item
From the given data:


So, we have:




Calculate 



Remove bracket

This means that:
is the mean of 15th and 16th item
From the data:


So:



Recall that:


Answer:
The scale factor is 1.
Step-by-step explanation:
Let k be the scale factor of a dilation of triangle ABC to form the image triangle A'B'C'.
The dilation is a magnification if

In this case, the preimage will be similar to the image triangle.
If

the dilation is a reduction. The image and pre-image will still be similar.
But if

the image is the same as the preimage.
We say the pre-image is congruent to the image triangle.
