Question

you weigh 5 kittens all from the same litter and get the following data (in pounds): 1.05, 1.2, 1.15, 1.2, 1.4. calculate the average weight of the kittens, in pounds. (1 point) 1.15 1.3 1.0 1.2

Explanation:

Step1: Sum the weights

To find the average, first sum all the weights. The weights are \(1.05\), \(1.2\), \(1.15\), \(1.2\), and \(1.4\). So, \(1.05 + 1.2 + 1.15 + 1.2 + 1.4\). Let's calculate that: \(1.05 + 1.2 = 2.25\); \(2.25 + 1.15 = 3.4\); \(3.4 + 1.2 = 4.6\); \(4.6 + 1.4 = 6\). So the sum is \(6\).

Step2: Divide by the number of kittens

There are 5 kittens. The formula for the average (mean) is \(\frac{\text{Sum of values}}{\text{Number of values}}\). So we divide the sum (\(6\)) by \(5\): \(\frac{6}{5}=1.2\).

Answer:

1.2
