It will be 5.15-w= minimum wage in 1996. Your keyword in that word problem would be when they said that 5.15 was w more than the minimum wage in 1996. I hope I helped ya :)
The answer is x<-2.
Hope this was correct :)
Standard form (which I assume is what they want you to turn these into) is y=mx+b.
12x-5y=20 is y=2.4x-4.
Subtract 12x from both sides, -5y=-12x+20.
Multiply both sides by -1, 5y=12x-20.
Divide both sides by 5, y=2.4x-4.
y=x+4 is already in standard form- I'm not quite sure what to do.
3x+y=3 is y=-3x+3.
Subtract 3x from both sides, y=-3x+3.
x=-y+3 is y=-x+3
Ad y to both sides, y+x=3.
Subtract x from both sides, y=-x+3.
Answer:
CI = x ± 2.58 (s / √n)
Step-by-step explanation:
The confidence interval is the mean plus or minus the margin of error. The margin of error is the critical value times the standard error. For a normal distribution, the critical value is the z-score at the given confidence level. The standard error is the standard deviation divided by the square root of the sample size.
CI = x ± z (s / √n)
At 99% confidence, z = 2.58.
CI = x ± 2.58 (s / √n)
