Answer:
y = 5/2x - 5
Step-by-step explanation:
Step 1: Write equation
5x - 2y = 10
Step 2: Solve for <em>x</em>
- Subtract 5x on both sides: -2y = 10 - 5x
- Divide both sides by -2: y = -5 + 5/2x
- Rewrite: y = 5/2x - 5
Answer:
Step-by-step explanation:
(8-5)/(1-0) = 3/1 = 3
y - 5 = 3(x -0)
y -5 = 3x - 0
y = 3x + 5
Your goal is to isolate the x variable, so all you have to do here is subtract 6 on both sides.
Your final answer is x ≤ 2.
Hope this helps a lot! :)
I believe the answer would be 10.5 inches per hour.
Answer:
The expression is 
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the z-score that has a p-value of 
.
The margin of error is of:
90% confidence level
So 
, z is the value of Z that has a p-value of 
, so 
.
What expression would give the smallest sample size that will result in a margin of error of no more than 3 percentage points?
We have to find n for which M = 0.03.
We have no prior estimate for the proportion, so we use 
. So
The expression is
