Answer:
A. $18
B. $200
C. 
Step-by-step explanation:
Function:
<u>Parts A and B:</u>
The price that generates the maximum profit is ate vertex of parabola. Find the coordinates of the vertex:
The price that generates the maximum profit is $18
The maximum profit is $200
<u>Part C:</u>
The company breaks even when the profit is positive. From the graph of the function you can see that the graph of the function is over p-axis for all , so the positive profit is for
In p=16 and p=20, the profit is 0 and when p<16 and p>20, there will be a loss.
Answer:
Step-by-step explanation:
Without any calculations, you can eliminate Apple and Google: both of them suffered looses. Neither went up. They went down. eBay went up ever so slightly (0.09 on nearly 21 dollars). At least it did not loose money on the day. So it is possible.
Netflix went up $2.73 on a stock that was about 118 on it's close. So while ebay only made $.09, Netflix was the winner on the day both in absolute and % terms.
Answer: 424.115
Step-by-step explanation:
(Pi)6^2(5) =565.49
3/4 = 424.115
Explanation:
Since we have given that
The prices of three t-shirts styles i.e $24, $30, $36 with their probability is given by
As we know that,
Now,
and
So,
So, the expected value of a t-shirt = $31.
Answer:
We conclude that the sonnets were written by by a certain Elizabethan poet.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 8.9
Sample mean, 
=10.2
Sample size, n = 6
Alpha, α = 0.05
Population standard deviation, σ = 2.5
First, we design the null and the alternate hypothesis
We use One-tailed z test to perform this hypothesis.
a) Formula:
Putting all the values, we have
Now, 
b) We calculate the p value with the help of z-table.
P-value = 0.1003
The p-value is greater than the significance level which is 0.05
c) Since the p-value is greater than the significance level, there is not enough evidence to reject the null hypothesis and accept the null hypothesis.
Thus, we conclude that the sonnets were written by by a certain Elizabethan poet.
