Answer:
1792
Step-by-step explanation:
Probability =
(number of ways it can come out the way you want)
divided by
(total number of ways it can come out).
Total number of ways to draw a marble = 30 (marbles in the bag).
Number of ways it can succeed = 15 (number of red or green ones)
Probability = 15/30 = 1/2 = 50% .
Answer:
x = -1 /2= -0.5 y = 15 /10= 1.5
Answer:
y = -3x + 15
Step-by-step explanation:
Parallel means they have the same gradient.
So we know that y = -3x + c
Now we solve for C by substituting the values at the point - (4,3)
y = -3x + c
3 = -3(4) + c
3 = -12 + c
3 + 12 = c
15 = c
y = -3x + 11
Answer:
b = 3/4
Step-by-step explanation:
Using point slope: y - y1 = m(x - x1).
Substitute your given slope, given point, and subsitute 0 in for x and solve for y since the y intercept is the y value when x = 0.
0.2 = 1/5, so 1/5 * 1/4 = 1/20
Therefore: y - 4/5 = 1/4(0 - 0.2) → y - 4/5 = -1/20 → y = 4/5 - 1/20 → 15/20 → <em>3/4</em>
