Answer:
C. Bottling plant B (with 175,000 sports drinks per day), because the daily mean will be closer to 20 fluid ounces with more sports drinks in the sample.
Step-by-step explanation:
The general rule is that the larger the sample, the closer the sample mean will be to the population mean. This happens because the standard deviation of our sample is given by the following formula:
In which is the standard deviation of the mean volume of all of this type of sports drinks and is the size of the sample. So as increases, the less variation there will be, and the closer the sample mean will be to the population mean, that is, the closer the population mean is going to be closer to a mean volue of 20 fluid ounces.
So, the correct answer is:
C. Bottling plant B (with 175,000 sports drinks per day), because the daily mean will be closer to 20 fluid ounces with more sports drinks in the sample.
Answer:
The equation would be 7.50x + 15=90
Step-by-step explanation:
So the the total you are trying to find is 90. So the equation would equal 90. Now since we are trying to find a unknown variable we use x. This results in 7.50x. Now 15 is a known variable so it will just stay the same. The amount of hours would be 10.
Answer:
m = 3/2
Step-by-step explanation:
The slope of a line is m = rise / run.
As we move from P to Q, x increases from -8 to -5 (3 units) and y decreases from -10 to -12 (2 units). Hence, the slope of this line is m = rise / run
and m = -2 / 3.
Any line perpendicular to this line has a slope which is the negative reciprocal of this.
(slope of perpendicular line) = -1 / (-2/3) = 3/2
