Answer:
2x-3>15 and 3-7x>17 =
3-7x>17
-7x>14
x<-2
Step-by-step explanation:
Sorry this is not a proper equation. I think you meant this equation.
2x-3>15 and 3-7x>17
for this equation the answer is
3-7x>17
-7x>14
x<-2
The mean = 2,000
s = Sigma ( standard deviation ) = 300
M - 2 s = 2,000- 2 * 300 = 2,000 - 600 = 1,400
M + 2 s = 2,000 + 2 * 300 = 2,000 + 600 = 2,600
Answer.
Useful life of light bulbs within 2 standard deviations of the mean is:
A ) Between 1,400 and 2,600 hours
6.23 is the answer you get that by square root 40
Step-by-step explanation:
4. y=-6/3x+3 (if you can simplify put y=-2x+3)
5. y=5/2x+1
6. y=-8/2x -5 (if you can simplify put y=-4x-5)
7. y=-6/6x+2 (if you can simplify put y=-x+2)
8. y=4/6x-4 (if you can simplify put y=2/3x-4)
9. y=6/5x+0
hope this helped!!!
