Ihave to figure out the mean of 11+12+12+13+12 divided by 12 and what i have so far is: 23+25+12 divided by 48+12 divided by 60 divided by 12 and my answer was 24, but 24 times 12 equals 288 so could someone me out here?

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

ou would have 12 of each
