Answer: See explanation.
Step-by-step explanation:
You need to put a little X on the graph down at the bottom on the ticks that represent 1/2, 3/4, 1 1/4, and 2.
Here mark the angles
- m<FHG=75
- m<FGH=55
- m<GHI=59°
- m<GIH=63°
By using angle sum property
So
- m<FGH < m<IGH <m<GHI <m<GIH <m <FHG
So
A researcher analyzed the results of her data and calculated the standard deviation of scores at 3.5. what is the variance?
Solution: We are given the standard deviation of scores = 3.5
We know that the variance is the square of the standard deviation.
Therefore, the variance is:



Therefore, the variance of the scores is 12.25
Perpendicular Transversal Theorem <span>can be used to prove that d is perpendicular to t.
The theorem states that : </span><span>In a plane, if a line is perpendicular to one of the 2 parallel lines then it is perpendicular to the other.</span>
