Question

Winnie measured the length of her father's ranch four times and got four different distances. Her measurements are shown in the table. To estimate the actual length, Winnie first approximated each distance to the nearest hundredth. Then she averaged the four numbers. Using a calculator, find Winnie's estimate. Round to two decimal places, if necessary. The first distance is 61, the second distance is 58, the third distance is 74, and the fourth distance is 72. Winnie's estimate is:

A) 63.75
B) 65.25
C) 66.25
D) 65.75

Answer 1

Winnie's correct estimate for the length of her father's ranch is 66.25, after averaging her four measurements of 61, 58, 74, and 72.

Step-by-step explanation:

To estimate the actual length of her father's ranch, Winnie measured the length four times and recorded the following distances: 61, 58, 74, and 72 units. According to the question, she then approximated each distance to the nearest hundredth (which, given these are whole numbers, would stay the same) and averaged the four numbers to find her estimate.

The steps to the calculation are as follows:

1. Add the four measurements: 61 + 58 + 74 + 72 = 265.
2. Divide the sum by the number of measurements to find the average: 265 ÷ 4 = 66.25.

Therefore, the correct answer is C) 66.25.
