Answer:
About 1.23 standard deviation above the mean
Step-by-step explanation:
From what we have here, we need to calculate the difference between the given value and the mean and divide by the standard deviation
That would be through calculating the z score as follows;
z-score = (x - mean)/SD
where x is the given value
z-score = (87-71)/13 = 1.23
Since the score is bigger than the mean, the correct choice here is that the score is about 1.23 standard deviation above the mean
Answer:

Step-by-step explanation:
step 1
Find the slope
we have
(0,-6) and (1,4)
The slope is equal to

step 2
Find the equation of the line in slope intercept form
The equation of the line in slope intercept form is

we have

-----> y-intercept (given value in the table)
substitute

Let's plug in a few points to see which graph belongs to the function f(x) = 2x^2
Let's say x =0, let's find y!
2(0)^2 = 2(0) = 0
So one point on our line is (0.0)
Just finding this point right here eliminates 3 of the answer choices. Your answer is the graph that goes through the point (0,0)
For your added convenience, I have attached the graph. :)
Answer:
(-1,0)
Step-by-step explanation:
3(-1)+3(0)=-3
-3+0=-3
-3=-3
-2(-1)+(0)=2
2+0=2
2=2
Answer:
there is no solution, meaning the lines would be parallel
