Answer:
Mean: 6.8
Median: 2
Mode: There is no mode of the data set
Step-by-step explanation:
Finding the mean: 5+8+2+9+10= 34 divided by the numbers of the data set which is 5= 6.8
Finding the median: The middle of the data set which is 2
Finding the mode: the most frequently occurring number which doesn't appear in this data set which means there is none.
Answer:
a) $50,880
b) $48
c) 1060
Step-by-step explanation:
a)
-320x^2 + 1920x + 48000 = 0
This is a parabola that opens downward. It has a maximum value. The maximum value occurs at x = -b/(2a)
x = -b/(2a) = (-1920)/(2(-320)) = 1920/640 = 3
The maximum revenue, y, is the value of the function evaluated at x = 3.
f(x) = -320x^2 + 1920x + 48000
f(-3) = -320(3)^2 + 1920(3) + 48000
f(-3) = 50,880
The maximum revenue is $50,880
b)
Since maximum revenue occurs at x = 3, and since x represents the number of $4 discounts, the discount is 3 * $4 = $12. The price is $60 - $12 = $48
c)
$50,880/$48 = 1060
