<span>A.
Half the students were failing the course near the end of the school year.
The sentence is written in passive voice because the course is the subject of the sentence and was being failed is the main verb phrase. The course can't fail. The students are the ones who are failing so to change it you must make the students the subject of the sentence. A is the only option that makes the students the subject.

Answer:
a = –0.4 and b = 0.15
Explanation:
<em>Shanti wrote the predicted values for a data set using the line of best fit y = 2.55x – 3.15. She computed two of the residual values. What are the values of a and b?</em>
<em />
Residual values are the difference between Given and predicted value. That is:
Residual Value = Given - Predicted
Taking the values of the table:
a = 4.1 - 4.5 = -0.4
a = -0.4
And b is:
b = 7.2 - 7.05 = 0.15
b = 0.15
That means right answer is:
<h3>a = –0.4 and b = 0.15</h3>
