Answer:
6/95.
Step-by-step explanation:
Prob(red marble on the first choice) = 4/(10+6+4)
= 4/20
= 1/5.
Prob(green marble on the second draw) = 6/19.
Prob( read then a green)
= 1/5 * 6/19
= 6/95.

Answer:
The equation of the straight line is x - 2y +6 =0
Step-by-step explanation:
<u>Explanation:</u>-
Given a point ( 2, 4) and slope m = 
The equation of the straight line passing through the point and having slope 'm'
y - y₁ = m ( x - x₁)
y - 4 =
( x - 2)
2( y -4) = ( x-2)
2 y - 8 = x -2
x - 2 y - 2 + 8 =0
x - 2y + 6 =0
The equation of the straight line is x - 2y +6 =0
Answer:
C, assuming you left off the y on the 30
Step-by-step explanation:
30(.5x-2)+40(.75y-4)
Distribute
15x-60+30y-160
Simplify
15x+30y-220
