Answer:
B
Step-by-step explanation:
Before outlier : 7.25
After outlier : 4
7.25 - 4 = 3.25
So the mean decreases by 3.25 when the outlier is removed.
Answer:
cost of producing the 501st item = $9.92
Step-by-step explanation:
The function representing the cost is given by;
C(x) = 10000 + 90x - 0.08x²
To get the cost of producing the 501st item, we have to first find the cost of producing 500 items and then do the same for 501 items then subtract the values gotten.
Thus;
C(500) = 10000 + 90(500) - 0.08(500)²
C(500) = 10000 + 45000 - 20000
C(500) = $35000
Similarly;
C(501) = 10000 + 90(501) - 0.08(501)²
C(501) = 10000 + 45090 - 20080.08
C(501) = $35009.92
cost of producing the 501st item = C(501) - C(500) = 35009.92 - 35000 = $9.92

To find:
Degree of the polynomial
Solution:
Degree of a polynomial:
The degree of the polynomial is highest power of the variable in the polynomial.
Here, the highest power is 4.
The degree of the polynomial is 4.
