Answer:
E. 10 and 10
Step-by-step explanation:
Standard Deviation is the square root of sum of square of the distance of observation from the mean.
where, 
is mean of the distribution.
Here, since standard deviation is the ratio of the distance from the mean and sample size. So for decreasing the standard deviation we should keep numerator constant and increasing the denominator.
This can be only possible in option (E).
Hence, only Option (E) is correct.

Answer:
Domain: All real numbers
or
Range: All real numbers
Or
Step-by-step explanation:
The given function is 
This a polynomial function of degree 1.
Polynomial functions are continuous everywhere.
The function is therefore defined for all real values of 
.
The domain is
If we let 
Then, 
.
is also defined for all real values of 
, hence the range is also all real numbers or
Answer:
Step-by-step explanation:
f(x)= -4x+9 solve f(c+2)
f(c+2) = - 4 (c+2)+9 = -4c -8+9
f(c+2) = - 4c +1
