Answer:
D
Hey There!
To find the answer you have to add the frequencies of all of them and take the frequency of 3 people being in a car and divide that by the sum of all of the frequencies if that makes sense
37+98+40+25=200
The frequency of 3 people being in a car is 40
so we would do
which is equal to
Therefore D is your answer
Answer:
(a)
(b)
(c)R'(5400)=$394
Step-by-step explanation:
Given that x is the quantity demanded and the speaker's unit price (in dollars) is p where:
p = −0.02x + 610 (0 ≤ x ≤ 20,000)
(a)Revenue function R.
Revenue = Price X Quantity Demanded
Therefore:
R(x)=xp
(b)Marginal revenue function R'(x)
If
Then, the marginal revenue function
(c)We want to compute R'(5,400)
From the above, we can infer that the revenue that will be generated on the sales of the 5401st item is $394.
