Answer:
y=3x-2
Step-by-step explanation:
y = 3x+ 2 ; y= 3x - 2 is a system of equations with no solution.
The sample size should be 73.
We use the formula
To find the z-score:
Convert 95% to a decimal: 0.95
Subtract from 1: 1-0.95 = 0.05
Divide by 2: 0.05/2 = 0.025
Subtract from 1: 1-0.025 = 0.975
Using a z-table (http://www.z-table.com) we see that this value goes with a z-score of 1.96. Using this, our value for σ and our margin of error, we have:
The answer is 9:1 cause it’s the only one set to 1
Answer:
true because when you add negatives it's the same as subtracting, so, you're just going further negative
