Answer:

-\sqrt{6}

Step-by-step explanation:

Because the square root of 6 cannot be simplified any further without getting a mess of decimals, you would treat it as if it were an "x" in this scenario. Simply subtract 4 from 3 to get -1, and -1 multipled by the square root of 6 is just -\sqrt{6}.

In order to determine the number of squirrels in a conservation area, a researcher catches, and marks 114 squirrels then release
vodomira [7]

Answer:

456 squirrels

Step-by-step explanation:

We have the following formula:

N = M * C / R

Where "N" is the estimated population size, "M" is the number of individuals already tagged, "C" is the total number of those caught the second time regardless of whether or not they are tagged, and "R" is the total number of tagged recaptured individuals.

Now, replacing we have:

N = 114 * 96/24

N = 456

Therefore, there are approximately 456 squirrels in the conservation area.

Vlad [161]

Answer:

The shrinkage as a percentage of sales is 1.6%.

Step-by-step explanation:

In order to find the percentage of the sales that can be contributed to shrinkage, we first need to find the amount of shrinkage between the book value ($907,340) and the physical inventory ($875,435).  The difference between these two values is $31,905.  With this value of shrinkage, I then divide by the total amount in sales, which is $1,988,345.  This would give me an overall percentage of 1.6%, which represents the shrinkage as a percentage of sales.
