Answer:
Option B
Step-by-step explanation:
Given that the regression equation using least squares for test scores and student teacher ratio is
Test Score = 557.8 + 36.42 In (Income).
Say if 1% income is increased.
Let income be 100
New income = 101
Then we have
Test score original =
Test score new income
= 
Increase = 0.362~0.36
Option B is right.

The answer is C,
Coterminal when involving angles is an angle that is 360 degrees greater or lesser. In order to find whether something is coterminal or not you take one of your angles and subtract or add 360 from it until you reach that number. If you add/sub 360 and you can't ever equal the other number than they are not coterminal.
Example:
591 - 360 = 231
So that means
231 degrees = 591 degrees
Example 2:
51 - 360 = 309
51 + 360 = 411
411 + 360 = 771
771, 411, and 309 /= 591 or 231
So 51 degrees /= 231 or 591
C: 51 is not coterminal!

We know that 70% of all comic book fans are male, and that 40% of Company A fans are male.
Since 25% of all comic book fans are company A fans:
0.4 * 0.25 (meaning 40% of 25%) = 0.1, or 10% of all comic book fans are male company A fans.
What percentage, then, of male comic book fans are company A fans?
0.1 ÷ 0.7 = 0.142
We divide 10%, the percentage of all comic book fans that are male and company A fans, by the percentage of comic book fans that are male, since we are given that the fan is male.
Answer is 0.14
