Step-by-step explanation:
Step 1: Calculate the mean. Step 2: Calculate how far away each data point is from the mean using positive distances. These are called absolute deviations. Step 3: Add those deviations together. Step 4: Divide the sum by the number of data points.
Answer:
Its 225
1200 divided by 225 is 3
56.7 and 123.3
delta math
3x+2=-x+10
3x+2+x=-x+10+x
4x+2=10
4x+8
4x/4=8/4
x=2
The solution set is {2}
