Step-by-step explanation:
Given f(x) divided by (x + h) then the remainder is the value of f(- h)
Here
f(x) = 3x³ - 5x² - 47x + k ← k is the constant term , then
f(- 3) = 3(- 3)³ - 5(- 3)² - 47(- 3) + k = 0 , that is
3(- 27) - 5(9) + 141 + k = 0
- 81 - 45 + 141 + k = 0
15 + k = 0 ( subtract 15 from both sides )
k = - 15

The standard deviation is 
Step-by-step explanation:
The standard deviation of a sampling distribution is the standard error or a valuation of the standard deviation. Where statistic parameter is the mean it is referred to as the standard error of the mean.
The formula for standard deviation of a sampling distribution is as follows;
Where;
= Sample proportion of rabbits with white markings from R
= Sample proportion of rabbits with white markings from S
= Number of from R = 50
= Number of from S = 100
Therefore, the standard deviation of the sampling distribution is given as follows;
.
