Answer:
50
Step-by-step explanation:
Each question is 6%/3 = 2% worth. If each question is worth 2% then total questions must be 50 (cuz that would be 2% x 50 (total question) = 100%).
The slope is 1/6
130 expected hits
520 attempts times 0.25 is 130
Slope 2; passes through (-5,1)
the answer is
y-1=2(x+5)
