First of all you times the top and the bottom together;
(11*17)/(34*19) = 187/646

Then you can simplify this;
187/646 = 11/38

Hope this helps! :)

A professor determined the relationship between the time spent studying (in hours) and performance on an exam.

kykrilka [37]

Step 1: Insert 2.6 hours for the variable of time and solve.
70.443 + 4.885(2.6)
70.443+ 12.701
= 83.144
This is Ann's EXPECTED exam score. Because of the concert, Ann scored 16 points lower than this number.
Step 2: Subtract 16 from Ann's expected score.
83.144 - 16
= 67.144
