1.) 7,056 * 41 = 289,296 (apple barrel volume * no. of barrels sold)
5,826 * 41 = 238,866 (cranberry barrel volume * no. of barrels sold)
2.) Subtract cranberry barrel volume from apple barrel volume
289,296 - 238,866 = 50,430 cubic inches
3.) Convert 50,430 cubic inches to liters
50,430 = 826.39 liters or 826.40 liters (rounded off)
4.) Therefore, 826.40 liters is the discrepancy in the shipment volume.

Answer:
The percent for 3 out of 12 is 25%
If the total number of games was 100, the win amount would need to be 25.
Step-by-step explanation:
3 out of 12 is a fraction - 3/12
3/12 = 0.25 which means 25% because 0.25 is 25% of 1.
Using the same percentage for 100 total games, you just multiply 100 by 0.25, the decimal version of the percentage.
Answer:
The 90% confidence interval for the mean nicotine content of this brand of cigarette is between 20.3 milligrams and 30.3 milligrams.
Step-by-step explanation:
We have the standard deviation for the sample, so we use the t-distribution to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 9 - 1 = 8
90% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 8 degrees of freedom(y-axis) and a confidence level of
. So we have T = 1.8595
The margin of error is:
M = T*s = 1.8595*2.7 = 5
In which s is the standard deviation of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 25.3 - 5 = 20.3 milligrams
The upper end of the interval is the sample mean added to M. So it is 25.3 + 5 = 30.3 milligrams.
The 90% confidence interval for the mean nicotine content of this brand of cigarette is between 20.3 milligrams and 30.3 milligrams.
