9 because if you subtract 11 from 19 you het 9
Answer:
16,667
Step-by-step explanation:
The company will "break even" when revenue is equal to cost.
R(x) = C(x)
3.2x = 2.6x + 10000 . . . . substitute the given expressions for R(x) and C(x)
0.6x = 10000 . . . . . . . . . . subtract 2.6x
x = 16,666 2/3 . . . . . . . . . divide by 0.6
The company must sell 16,667 lanterns to break even.
The median is the value that can be found in the middle of any data set. After plotting the values on the line plot (shown in the attached image), we can write out our data (shown under neath the line plot).
Then, we start by crossing off one value on each side of the data to work our way towards the middle. Once we come to the middle, we see that there are two values in the middle: 6 and 6.
To find the median when we have two values in the middle, we must add them, then divide by two.
6 + 6 = 12
12 ÷ 2 = 6
So, the median for this data set is 6.
