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:
a. 25%
b. $1560
c. $130
Step-by-step explanation:
a.
If 75% is paid by company, the rest is paid by Ruth.
Out of 100%, 75% is paid by company, so Ruth pays 100 - 75 = 25%
b.
Per year, the total amount paid is 6240, but Ruth pas 25% of this. So,
25% = 0.25
To get the answer, we multiply 0.25 with 6240.
0.25 * 6240 = 1560
So, $1560 is paid by Ruth annually.
c.
Since 1560 is paid annually (in 12 months), each month Ruth has to pay:
1560/12 = $130
Hence, $130 is deducted each month from her paycheck
We can write the domain and range in interval notation, which uses values within brackets to describe a set of numbers. In interval notation, we use a square bracket [ when the set includes the endpoint and a parenthesis ( to indicate that the endpoint is either not included or the interval is unbounded.
The answer is C.1/2 because there is only possible numbers are 3,5,6.
