Question

5.3 row game: calculations
work independently on your column. partner a completes the questions in column a only and
partner b completes the questions in column b only. your answers in each row should match.
work on one row at a time, and check if your answer matches your partner’s before moving on. if
you don’t get the same answer, work together to find any mistakes.

Explanation:

Row 1 - Column A: Calculate the mean of 1, 1, 1, 2, 100

Step1: Sum the numbers

The sum of the numbers is \(1 + 1 + 1 + 2 + 100 = 105\).

Step2: Divide by the count of numbers

There are 5 numbers. So the mean is \(\frac{105}{5}=21\).

Step1: Sum the numbers

The sum of the numbers is \(20 + 20 + 20 + 20 + 25 = 105\).

Step2: Divide by the count of numbers

There are 5 numbers. So the mean is \(\frac{105}{5} = 21\).

Step1: Order the numbers

First, we order the numbers from smallest to largest: \(1, 4, 6, 9, 10\).

Step2: Find the middle number

Since there are 5 numbers (an odd count), the median is the middle number, which is the 3rd number. So the median is 6.

Answer:

21
