mean is 20; 6,22,7,36,x what is the value of x
It would help if you proofread your questions before you posted them. Though not sure, I assume the numbers after the mean are the raw scores.
mean = Σx/n
20 = (6+22+7+36+x)/5
Solve for x.
20x5=100
6+22+7+36=71
100-71=29
X=29
double check
6+22+7+36+29=100
100/5=20
To find the value of x in the given set of numbers, we need to find the missing value that would make the average of the set equal to 20.
The mean (average) is calculated by dividing the sum of all the numbers by the total number of values. In this case, we need to calculate the sum of the given numbers and then divide it by the total count of numbers, including x.
Let's calculate the sum of the given numbers first:
6 + 22 + 7 + 36 + x
The average is given to be 20, so we can set up the equation:
(6 + 22 + 7 + 36 + x) / (5 + 1) = 20
To solve for x, we can multiply both sides of the equation by (5 + 1) to remove the denominator:
6 + 22 + 7 + 36 + x = 20 * (5 + 1)
71 + x = 120
Next, let's isolate x by subtracting 71 from both sides of the equation:
x = 120 - 71
x = 49
Therefore, the value of x is 49.
