Answer: Check explanation
Step-by-step explanation: (3,-5), because that's the point where the two lines intersect.
Y=-2x+1
Y=-3/2x-1/2
Substitute the Y to get -2x+1=-3/2x-1/2
1/2x=3/2
x = 3
Now plug x into first equation: y=-2*3+1=-5
so the intersection point is (3,-5)

Answer:
x = -8
Step-by-step explanation:
Answer:
0.3667
0.2727
Step-by-step explanation:
a)
P (Blue) = P (large and Blue) + P (mid and Blue) + P (small and Blue)
P (Blue) = (0.5 * 0.2) + (0.4*7 / 12) + (0.1* 1 / 3)
P (Blue) = 0.3667
b)
Conditional Probability:
P (Large / Blue ) = P (large and Blue) / P ( Blue)
P (Large / Blue ) = 0.5*0.2 / 0.36667
P (Large / Blue ) = 0.2727
