Liam works at a zoo. He was looking at some data showing the masses of their 5 African elephants. The mean mass of elephants was 3,800 kg, and the median mass was 3,600 kg. The smallest elephant named Lola weighed 2,700. Lola then got very sick and lost weight until her mass reached 1,800 kg. How will Lola’s mass decreasing affect the mean and median?

The mean will decrease, and the median will stay the same.

Step-by-step explanation:

The mean is affected by increasing or decreasing numbers  Lola's mass decreased from 2700kg to 1800 kg, resulting in a change of the mean. However the median stays the same because it is the middle number, only adding or losing an elephant in this case would affect the median.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
