The mean of four numbers is 59

The numbers are 52, 57, 58 and p
Find the value of p

1 answer

To find the value of p, we can use the formula for the mean:

Mean = (sum of all the numbers) / (number of numbers)

Given that the mean is 59, and there are four numbers (52, 57, 58, and p), we can set up the equation:

59 = (52 + 57 + 58 + p) / 4

To solve for p, we can multiply both sides of the equation by 4 to get rid of the fraction:

59 * 4 = 52 + 57 + 58 + p

236 = 167 + p

Next, subtract 167 from both sides of the equation:

236 - 167 = 167 - 167 + p

69 = p

Therefore, the value of p is 69.
