Answer:
539
Step-by-step explanation:
Let the total population of grizzly bears=x
In the first capture, 97 were tagged.
Therefore, ratio of the total population to the tagged=x:97
A month later, when 200 bears were captured, 36 were tagged.
Ratio of the sample to the tagged=200:36
Since a sample is representative of the population, the ratios are the same. We therefore have:
x:97=200:36
There are about 539 grizzly bears in the population

Answer:
36
Step-by-step explanation:
2*n = what the expression says.
2*18 = 36 is the answer to n = 18
Whatever value is given to n you just multiply it by 2.
(22 + 15.50 + 2.75) 15
(22 * 15) + (15.50 * 15) + (2.75 * 15)
