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

Answer:
C) c || d by converse of corresponding angles
Step-by-step explanation:
Only corresponding angles where transversal b crosses lines c and d are shown. All answer choices involving a||b or interior angles can be eliminated from consideration.
The "corresponding angle" theorem tells you corresponding angles are congruent if the lines are parallel.
The converse of that theorem tells you the lines are parallel if the corresponding angles are congruent. Here, the angles are shown congruent, so the "converse" theorem applies.
