Answer:
416.8 pounds.
Explanation:
The mean weight of the 28 bears at a zoo is 413 pounds.
The Total Weight of the 28 bears = Mean weight × number of bears
= 413 pounds × 28 bears
= 11564 pounds
Fuzzy the bear, whose weight is 434 pounds, and Wuzzy the bear, whose weight is 505 pounds, were added to the zoo.
This means the total number of bears
= 30 bears because two additional bears were added
What is the new mean of the weight of the bears at the zoo?
New Mean = 11564 pounds + 505 pounds + 434 pounds/30 bears
= 12503 pounds /30 bears
= 416.76666667 pounds
Approximately to the nearest tenth = 416.8 pounds.
