Take the average for each machine:
Machine 1 Average = 311
Machine 2 Average = 311.25
Machine 3 Average = 311.75

lukebluefive · Answer

Average = (Sum of all values) / (Number of values)
Number of values = 8 in this case

workin on my ged

lukebluefive · Answer

Ah, well, hope that goes well.  I've heard it's tough.
Sorry, let me explain better this time.
First, sum all of the values for each machine, individually:
Machine 1 Total Dispensed = 2488 grams
Machine 2 Total Dispensed = 2490 grams
Machine 3 Total Dispensed = 2491 grams

lukebluefive · Answer

To get the average, or mean, you divide these numbers by the total number of values, or bags, in this case, which number 8:
Machine 1 Average Dispensed = 2488 / 8 = 311
Machine 2 Average Dispensed = 2490 / 8 = 311.25
Machine 3 Average Dispensed = 2491 / 8 = 311.75

The question is asking which machine outputs the most cereal on average.

	c. $56.00
	d. $98.00
	e. $196.00

lukebluefive · Answer

I'm above average, though it's not my specialty.  What do you need help with?

anonymous · Answer

the question i just sent forget the language arts for right now

lukebluefive · Answer

Well, since there are two speakers, each 28 feet from the central console, that'd be:
2 x 28 feet x $3.50 = 28 feet x $7 = ?
Assuming that two speakers can't share the same wire, which seems like a realistic assumption to me.
