What is the mean of the data set [3,2,2,12,6,5,14,4]?

A.2
B.4
C.6
D.7

6

Explanation:

To find the mean of a data set, add all the values in the set together, and then divide the result by the number of values in the set.

3 + 2 + 2 + 12 + 6 + 5 + 14 + 4 = 48

There are 8 values in the data set.

48/8 = 6

So the mean of the data set is 6.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
