Liam works at a zoo. he was looking at some data showing the masses of their 5 african elephants. the mean mass of the elephants was 3800 kg and the median mass was 3600 kg. the smallest elephant, named lola, weighed 2700 kg. lola then got very sick and lost weight until her mass reached 1800 kg. how will lola's mass decreasing affect the mean and median?
a. both the mean and median will decrease
b. the median will decrease, and the mean will stay the same.
c. the mean will decrease, and the median will stay the same.
d. the mean will decrease, and the median will increase.

How does increasing Omar's mass affect the median?

The median is the  3rd mass when the masses are put in order from least to greatest because there are 5 elephants.

Increasing Omar's mass (the 5th mass)  doesn't affect the 3rd mass, so the median stays the same.

How does increasing Omar's mass affect the mean?

Let's remember how to calculate the mean:

mean = total mass/ number of elephants

Increasing Omar's mass from 6000kg to 7000kg increases the total mass and doesn't change the number of elephants, so the mean increases.

Therefore -

no not all of them.

some of them have a square base.
