Answer

Step 4: Finally, take the square root of this result to find the RMS. That is \(\sqrt{16.67}\).

Steps

Step 1 ：Step 1: Calculate the square of each number. Thus we have \(3^2 = 9\), \(4^2 = 16\), and \(5^2 = 25\).

Step 2 ：Step 2: Add these squared numbers together to get \(9 + 16 + 25 = 50\).

Step 3 ：Step 3: Divide this sum by the total number of values, which is 3. So, we get \(\frac{50}{3} = 16.67\)

Step 4 ：Step 4: Finally, take the square root of this result to find the RMS. That is \(\sqrt{16.67}\).
