If 11 students in a team have respective weights of 46 kg, 45.5 kg, 49 kg, 46.5 kg, 50 kg, 47 kg, 48 kg, 47.5 kg, and 47.5 kg what will be the average weight in the team?
If 11 students in a team have respective weights of 46 kg, 45.5 kg, 49 kg, 46.5 kg, 50 kg, 47 kg, 48 kg, 47.5 kg, and 47.5 kg what will be the average weight in the team?
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.
