The weights, in pounds, of the upper class men offensive line players for a college are shown below: 322, 290, 321, 326, 330, 315, 311, 292, 290

What is the average, or mean, weight of the upper-class men offensive players? provide your answer with 3 sig figs.

1) 311 pounds
2) 315 pounds
3) 290 pounds
4) 318 pounds

311 pounds

Step-by-step explanation:

Here, we are to calculate the average weight of the upper-class men offensive players

To calculate this, we need to sum up all the weights and divide by their count

Mathematically, that would be;

Average weight = (322+290+321+326+330+315+311+292+290)/9 = 2,797/9 = 310.77778

Now this written in 3 significant figures would be 311 pounds

points are handed out whenever you post answers.

brainliest answers are handed out by the person asking the question, so whether your answer is picked depends entirely on whether the asker bothers to pick

if you're asking about your rank, it depends on having a certain number of points and a certain number of brainliest answers. for example, at the time of this writing, i have 44338 points out of 15000 needed for the next (nearly triple the requirement! ) but i only have 24 out of 50 required brainliest answers. this number decays, meaning after a certain amount of time (i think about a month), the total number of brainliest answers you've earned doesn't count toward this total. (i've been stuck at the same rank for a long

the lesson to learn here is that you shouldn't worry about points or rank. chances are, no matter how good an answer you may provide, your efforts will go mostly unnoticed unless you focus on the newest/most active questions that get posted.
