I'm fairly sure it is 0 because it is impossible to roll a number greater than 13 with a 12 sided die.
The answer for B is: 40 - (7.50 x 4) = 10 Because 7.50 x 4 = 30 and 40 - 30 = 10 So they are left with $10 after paying for the tickets
The answer for C is: Miguel and his 3 friends started with $40 and had a fee of $7.50 for each ticket and there are 4 people. 4 x 7.50 = 30 and 40 - 30 = 10 so they are left with $10 to spend on snacks and other stuff!
Idk the answer for D sorry about that!
Hope this helps!
Your first option y/x=1/4 is correct
In general, you just need to follow the formula for amplitude:v
y = A*sin(Bx - C) + D
The amplitude is |A|
For our problem <span>y = 5 sin 1/2x the amplitude and the answer to your question is 5.</span>
