Step-by-step explanation:
Answer: y = 5x + 13
<u>Step-by-step explanation:</u>
Parallel means it has the same slope.
Given line y = 5x + 5 --> the slope is 5, so parallel slope is 5
Use the Point-Slope formula: y - y₁ = m(x - x₁) such that
y + 2 = 5(x + 3) <em>input m and (x₁, y₁) into the Point-Slope formula</em>
y + 2 = 5x + 15 <em>distributed</em>
y = 5x + 13 <em>subtracted 2 from both sides</em>
Answer:
The easiest way of solving this is to eliminate one of the variables. If you multiply each of the equations by a number so you can add the equations together and have only one variable left, you can solve the single variable equation. Try multiplying the first equation by 11, the second by -10 and adding them, thus eliminating the y variable. After this, substitute that value you have for x and solve for y. I hope this helps.

Answer:
Option B) Reject null hypothesis
Step-by-step explanation:
We are given the following in the question:
We are given the null hypothesis:
Two tailed z-test
Now, 
Since,
The calculated z-statistic does not lie in the acceptance region, we fail to accept and reject the null hypothesis.
Left-tailed z-test
Now, 
Since,
We fail to accept and reject the null hypothesis.
Right-tailed z-test
Now, 
Since,
We fail to accept and reject the null hypothesis.
3) 1 lb=16 oz. multiply the number of lbs by 16 to get number of oz: 320x16=5,120. Since they want per month divide by 12: 5120/12=426.6667. Rounded to the nearest tenth: 426.7 oz. hope this helps :)
