Question

Carl is a biologist studying different types of mammals. He finds in one vally that there are 15 plant-eating mammals for every 2 meat-eating mammals. The total population is about 2,900. Which number is the beat estimate of the population of meat-eating mammals in the valley. * 170 *340 *1,450 * 2,560

Answer 1

Answer: 340

Explanation:

Given: There are 15 plant-eating mammals for every 2 meat-eating mammals.

i.e. ratio of meat-eating mammals to plant eating animals = 2:15 or
`\frac2{15}`

ratio of meat-eating mammals to total population =
`(2)/(17)`

Total population: 2,900 (approx.)

The population of meat-eating mammals in the valley =
`(2)/(17)*2900`

`\approx341`

From the given options, the best estimate of the population of meat-eating mammals in the valley = 340
