It would be the last answer because as you can see the line goes up for 2 hours and then goes straight for 1 hour than goes up again for 2. -The last option
Answer: The probability of rejecting the null hypothesis, when it is true, is 5%.
Step-by-step explanation:
We know that the level of significance ( denoted as 
) is generally the probability of rejecting the null hypothesis when it is true.
Therefore , If the level of significance (\alpha[/tex] ) 0.05, then it means that it is the probability of rejecting the null hypothesis when it is true.
i.e. The probability of rejecting the null hypothesis when it is true= 0.05
In percent : 
Hence, the correct option is : The probability of rejecting the null hypothesis when it is true is 5%.
Answer:
y = 2x - 3
Step-by-step explanation:
Start by writing out the given equation.
-2x + y = -3
The goal is to isolate the variable y.
For this equation, all you need to do is add 2x to each side.
-2x + y + 2x = -3 + 2x
Therefore, the answer is y = 2x -3.
I don't know if you are are familiar with the equation y = mx + b, but here's a little refresher. m is the slope, or in this case 2. b is the y-intercept, or in this case -3.
The equation y = mx + b is slope intercept form, so if you know this, you should be able to write any equation in slope intercept form.
