Mean is when you add all of them together and divide by the amount of data you collected. Mean is considered the average. So, all of them added together would be 14. Divide that by 7. You should get 2 and that is the average.
Answer:
There are no simple factors to this expression. You can however solve for x, giving you:
x = -1 ± √(y + 3)
Step-by-step explanation:
There is no simple pair of factors to this equation, so we'll have to go through the full process. You can see that by observing that there is no pair of rational numbers that add to make 2 and multiply to make -2. We can however solve for x:
