3. The diference of the means are 4.5

I’m sorry, I do not understand the last one.

Step-by-step explanation:

The mean is the average, add all of the values and divide the result by the number of values. The MAD is the mean absolute deviation. You find it by taking the distance between the values and the mean. You then add them together and divide it by the mean. I really hope this helps you!

Sarah bought pencils and markers for school. She bought 3 times as many pencils as markers.

Serhud [2]

Answer:

Sarah bought 30 pencils

Step-by-step explanation:

1. Let define p, as the number of pencils bought, and m, as the number of markers bought.

2.

$0.15p+0.30m=7.50$

$p=3m$

3. Substitute p in the first equation to 3m since p=3m as defined.

$0.15(3m) + 0.30m=7.50\\0.45m+0.30m=7.50\\0.75m=7.50\\m=10$

plug m into equation p=3m to find the number of pencils bought

$p=3m=3(10)=30$
