Answer:

A.Their means it will be most affected because this value will be an outlier.  

Step-by-step explanation:

The mean is found by adding together the data points and then dividing by the number of data points.  For this reason, the mean is most affected by an outlier, or a number very different from the others.

A high outlier will make the sum of the data points higher; this in turn makes the mean higher.

A low outlier means the sum of the data points does not increase as much as it would have with other numbers; this in turn makes the mean lower.

Since 65 is much lower than the other values, it is an outlier.  Including it will affect the mean the most.

Hiya!

Right now, both of their medians are 86. This means that both will get the same median if a 65 was added.

I believe A.) would be the correct answer, given it's pretty far away from 83 or 84. My second answer would be B.), but I'm not sure.

If you found this especially helpful, I'd appreciate if you'd vote me Brainliest for your answer. I want to be able to assist more users one-on-one! :)

Andreyy89

Answer: One book has a greater mass.

Step-by-step explanation:

Jamal has a pair of shoes with a total mass of 960 grams. This means that each shoe has a mass of:

960 grams ÷ 2= 480 grams per shoe.

Jamal also has four identical books with a total mass of 2 kilograms. Note that 1000 grams make a kilograms. Therefore 2 kilograms will be (2 × 1000 grams) = 2000 grams.

Each book will have a mass of:

2000 ÷ 4 = 500 grams per book.

One shoe has a mass of 960 divided 2 = 480 grams . One book has a mass of 2000 divided 4 = 500 grams . So one book has a greater mass.
