Answer:
Step-by-step explanation:
<u>Sum of 8 fifths and 4:</u>
- 8/5 + 4 =
- 1 3/5 + 4 =
- 5 3/5
<u>7 copies of the of sum of 8 fifths and 4:</u>
- 7 × 5 3/5 =
- 7( 5 + 3/5) =
- 35 + 7(3/5) =
- 35 + 21/5 =
- 35 + 4 1/5 =
- 39 1/5 or 39.2
A squared + b squared = c squared
8.6^2+14.7^2=c^2
73.96+216.09=c^2
square root both sides and...
c=17.03085
Your answer is A

Answer:
336 squirrels
Step-by-step explanation:
-This is a Mark-Recapture method.
-The population is estimated using the formula:

where:
- N-is the estimated population size.
- M-is the number of individuals tagged
- C- is the total number captured the second time(both tagged and untagged)
- R-is the total number of tagged individuals recaptured.
#We substitute our values as follows to estimate N:

Hence, there are approximately 336 squirrels in the conservation area.
*population is always rounded up to the next whole number.
