The sum of the draws from a box is 440. If the average of these draws is 2.20, how many draws were there?
Mean = (sum of scores)/(number of scores)
Solve for number of scores.
100
To find the number of draws, we can set up an equation using the given information. Let's denote the number of draws as "n".
The sum of the draws is given as 440, so we can write the equation as:
n * 2.20 = 440
This equation represents that the average of the draws multiplied by the number of draws is equal to the sum of the draws.
To solve for "n", we need to divide both sides of the equation by 2.20:
n = 440 / 2.20
Calculating this, we find:
n = 200
Therefore, there were 200 draws.
