Here are the solutions to the questions. 22. Step 1: Write the formula for the mean. The mean of a set of numbers is the sum of the numbers divided by the count of the numbers. Given numbers: 3, 5, 3x, 2. The count is 4. The mean is 4. Mean = (3 + 5 + 3x + 2)/(4) Step 2: Set up the equation and solve for x. 4 = (10 + 3x)/(4) Multiply both sides by 4: 4 × 4 = 10 + 3x 16 = 10 + ✂️ _That answer was long and got cut off.
