Answer:
Step-by-step explanation:
a) One can get maximum score when all the 20 questions answered are correct.
Maximum score = 20*3 = 60 points
b) Minimum score = 20 * (-2) = -40 points
c) Points for correctly answered questions = 10*3 = 30
Incorrectly answered questions = 14 - 10 = 4
Points for incorrectly answered questions = 4 * (-2) = -8
Total score = 30 + (-8) = 22
d) Points for correctly answered questions =5*3 = 15
Points for incorrectly answered questions = 13 * (-2) = -26
Total score = 15 + (-26) = -11
17 because 4 x 1.5 = 6, 50 / 1.5 = 33.33
The domain is three and the range is 68
12 girls out of 30 were selected, so the ratio "selected:tried" if 12/30. This fraction can be simplified into

Similarly, 16 boys out of 40 were selected, so the ratio "selected:tried" if 16/40. This fraction can be simplified into

So yes, the ratio of the number of students on the team to the number of students trying out the same for both boys and girls
