20 total marbles....7 are green
probability on first draw is 7/20...and since the marble was not replaced, the probability on the second draw is 6/19. And since they cant happen at the same time, we multiply
7/20 * 6/19 = 42/380 which reduces to 21/190
Answer:
Step-by-step explanation:
<em>Find the equation of the dashed line</em>
The line pass through the points
-----> is the y-intercept of the line
Find the slope of the line m
The formula to calculate the slope between two points is equal to
substitute the values
Remember that
The equation of the line into slope intercept form is equal to
we have
substitute
<em>Find the inequality</em>
we know that
The solution of the inequality is the shaded area below the dashed line
so
Answer:
False
True

Step-by-step explanation:
90/5 = 18 x 8 = 144 jars of paint
90/3 = 30 x 10 = 300 sketch pads
300:144 = 25:12

Answer:
- reflection across the x- and y-axes (in either order)
- reflection across the origin
Step-by-step explanation:
Rotation of a figure by 180° about the origin puts each of its points on the opposite side of the origin. That can be accomplished also by either of ...
- reflection across the origin
- reflection across the x- and y-axes, in either order
