Approximately 520 cards actually sold this year in the class, more than 505, have fulfilled their objective.
According to the question,
If the students sell c cards the,
The total revenue,
The total production costs,
`
The inequality of profit, or income, which is less than 10 thousand dollars represents their objective, such as:
→
→
→
→
or,
→
The class had to sell more than 505 cards just to meet their goals.
Thus the above answer is right.

Sample Answer for Edmentum
Answer:
Hot dogs - 27, soda - 81
Step-by-step explanation:
Soda to Hot dog ratio = 3:1
If the total is 108, we can divide 108/4 ---> 27
now, multiply 3 and 1 by 27 and there you go!
edit: also if you don't know why I divided 108 by 4, its because you add together both sides of the ratio
Completed question:
An initial time study resulted in an average observed time of 2.2 minutes per cycle, and a standard deviation of .3 minutes per cycle. The performance rating was 1.20. What sample size, including the 20 observations in the initial study, would be necessary to have a confidence of 95.44 percent that the observed time was within 4 percent of the true value?
Answer:
47
Step-by-step explanation:
When doing a statistic study, a sample of the total amount must be taken. This sample must be done randomly, and, to be successful, the sample size (n) must be determined, by:
Where Z(α/2) is the value of the standard normal variable associated with the confidence, S is the standard deviation, and E is the precision. The confidence indicates if the study would have the same result if it would be done several times. For a confidence of 95.44, Z(α/2) = 2.
The standard deviation indicates how much of the products deviate from the ideal value, and the precision indicates how much the result can deviate from the ideal. So, if it may vary 4% of the true value (2.2), thus E = 0.04*2.2 = 0.088.
n = [(2*0.3)/0.088]²
n = 46.48
n = 47 observations.

Answer:
(a) The sample size required is 2401.
(b) The sample size required is 2377.
(c) Yes, on increasing the proportion value the sample size decreased.
Step-by-step explanation:
The confidence interval for population proportion p is:
The margin of error in this interval is:
The information provided is:
MOE = 0.02
(a)
Assume that the proportion value is 0.50.
Compute the value of n as follows:
Thus, the sample size required is 2401.
(b)
Given that the proportion value is 0.55.
Compute the value of n as follows:
Thus, the sample size required is 2377.
(c)
On increasing the proportion value the sample size decreased.
