Answer:
1 in 10, or 10% because there is a 90% chance she will choose the wrong number.
Step-by-step explanation:
1-10 is 10 numbers, only one of which is the correct one.
The resulting proportion is:
-40
-4 * 2 = -8
-8*-1= 8
12+8 = 20
20*(-2) =-40
Yes, they vary directly
y=kx; k is the constant (12 in this case) and as x increases y increases, so they vary directly
