Help please just this that is all Please help Solve equations algebraically geniuses only 1. y= x-2
y=4

2. y= x+8
y= -2

3. y=x-5
y=6

4. y= x+6
y= -4

5. y= x-9
y= 3

6. y= x+4
y= -x

7. y= x-5
y= 2x

8. y= x+ 12
y= 1/2x

9. y= x-8
y= 3x

10. y= -x-2
2x-3y= -9

11. y= 2x-1
y= x+1

12. y= 2x+2
4x-y= -6

13. 2x+2y=3 1/2
x-4y=-1

14. y=x-4
4x+y=26

15. x-2y=-25
3x-y=0

Abottled water distributor wants to estimate the amount of water contained in 1-gallon bottles purchased from a nationally known water bottling company. the water bottling company’s specifications state that the standard deviation of the amount of water is equal to 0.02 gallon. a random sample of 50 bottles is selected, and the sample mean amount of water per 1-gallon bottle is 0.995 gallon a. construct a 99% confidence interval estimate for the popula-tion mean amount of water included in a 1-gallon bottle. b. on the basis of these results, do you think that the distributor has a right to complain to the water bottling company? why? c. must you assume that the population amount of water per bottle is normally distributed here? explain. d. construct a 95% confidence interval estimate. how does this change your answer to (b)?
