What are the scale factor of ABC dilated to XYZ plz help

Explanation:

The order is important for ABC and XYZ so we can see what letters pair up.

Based on that, we can see that AB pairs with XY as they are the first two letters of ABC and XYZ respectively.

Divide the length XY over AB and reduce

XY/AB = 10/15 = 2/3

We could also divide XZ over AC

XZ/AC = 14/21 = 2/3

and we get the same ratio

Step-by-step explanation:

If a media research company increased the size of their random samples from 3,500 to 5,000, to get the percentage margin error, we will follow the steps;

Initial sample size = 3500

Final sample size = 5000

margin error = Final sample size - initial sample size

Margin error = 5000-3500

Margin error = 1500

%margin error = Margin error/Initial sample size * 100%

%margin error = 1500/3500 * 100%

%margin error = 3/7 * 100%

%margin error = 300/7

%margin error = 42.86%

This means that they improved their margin by 42.9% (to the nearest tenth)
