Clean up the equation with x first and x=12.
Substitute this value in to the other equation to solve for y.
You should get a solution of (12,-8)
Standard form: 100,000,000 (100 million)
Scientific form: 1 * 10
.
The value would be 5 itself because it is in the ones place. If it were in the tens place it would be 50, if it were in the hundreds place it would be 500, and so on. Hope this helps. Let me know if you need anything else or if I can clarify anything for you, and feel free to post more questions.
the outlier is 37 it affects the mean because
1)37+4+ 7+ 3 +11 +9+13+ 5=89
2)89 divide by 8 number= 11.1 , it give you a decimal number
