Question

a pet store has 7 cats. here are their weights (in pounds). 5, 16, 6, 9, 5, 6, 14 find the mean weight of these cats. if necessary, round your answer to the nearest tenth. pounds

Explanation:

Step1: Sum the weights

Add all the weights: \(5 + 16 + 6 + 9 + 5 + 6 + 14\)
\(5+16 = 21\), \(21+6 = 27\), \(27+9 = 36\), \(36+5 = 41\), \(41+6 = 47\), \(47+14 = 61\)

Step2: Divide by number of cats

There are 7 cats, so mean \(=\frac{61}{7}\approx8.7\) (rounded to nearest tenth)

Answer:

8.7
