First, in order to find the median you have to put each number in order from least to greatest.
Your median is the number in the middle.
In this case that number is 8.
If you have an even amount of numbers, you will have to convert that into a decimal.
Hopefully this has helped!
The possible digits could be 0, 1, 2, 3, or 4 as they would cause the entire number to round down instead of up.
Answer:
The number of elephant ears that must be sold to maximize profit is 400.
Step-by-step explanation:
Given that,
The profit that a vendor makes per day is given by
P(x)= - 0.004x² +3.2 x -200
where x is number of elephant ears.
P(x)= - 0.004x² +3.2 x -200
Differentiating with respect to x
P'(x)= - 0.008x+3.2
Again differentiating with respect to x
P''(x) = -0.008
For maximum or minimum P'(x)=0
- 0.008x+3.2=0
⇒0.008x=3.2

⇒ x = 400

Since at x=400, P''(x)<0, the profit is maximize.
P(400) = -0.004×400²+3.2×400-200
=440
The number of elephant ears that must be sold to maximize profit is 400.
