Answer:
The slope is 2.
Step-by-step explanation:
slope = rise/run
= 1-(-5) / 2-(-1)
= 6/3 = 2
Therefore, the slope is 2.
Answer:
Line B
Step-by-step explanation:
- Automatically, we can eliminate Line C, because the slope is negative, since the question's asking which one is the greatest slope. However, if you do want to find the slope of Line C, you can use the rise/run method or the slope formula. Using the coordinate sets (0, 0) and (1, -2) and applying y2-y1/x2-x1 = -2-0/1-0 = -2/1 = -2.
- Line A's slope is 1/2. You can either find this out by applying the rise/run formula (rise = 1, run = 2) or you can find 2 coordinate sets to solve for slope. In this case, I'll use (0, 0) and (2, 1). Using the formula y2-y1/x2-x1... 1-0/2-0 = 1/2.
- Line B's slope is 2. As stated in Line A, you can find this by applying the rise/run formula or using 2 coordinate sets. I'll use the points (0, 0) and (1, 2). Using the formula y2-y1/x2-x1... 2-0/1-0 = 2/1 = 2.
Since the question is asking which line has the greatest slope, the line that has the greatest slope would be Line B. (2 > 1/2 > -2)
We have to find the critical t value for 99% confidence level and sample size of 18.
Degrees of freedom = n - 1 = 17
α = 1 - 0.99 = 0.01
α/2 = 0.01/2 = 0.005
So, from the t table we have to check the value against the column 0.005 and for 17 degrees of freedom.
This value comes out to be 2.898.
So, <span>tα/2</span> = 2.898
Well 8 divided by 30 = .26 wich is one of the choices so that way might work.
