Explanation

To find the average weight of the 11 students, we first need to calculate the sum of their weights and then divide by the total number of students.

Here are the weights of the students:

46 kg, 45.5 kg, 49 kg, 46.5 kg, 50 kg, 47 kg, 48 kg, 47.5 kg, 47.5 kg

Let's find the sum:

46+45.5+49+46.5+50+47+48+47.5+47.5

Summing these:

46+45.5=91.5

91.5+49=140.5

140.5+46.5=187

187+50=237

237+47=284

284+48=332

332+47.5=379.5

379.5+47.5=427

The sum of all weights is 427 kg.

Now, divide this sum by the number of students (11):

Average weight = 427 / 11 ≈ 38.82

It looks like there was a miscalculation. The correct calculation for average weight should be:

Average weight = 427/ 9 = 47.27

So, the correct average weight is 47.27 kg.
