5+6+4=15
blue marble = 6 out of 15
replacing blue marble for black = 4 out of 14
0.5 times 0.2 equals 0.1.
0.5 * 0.2 = 0.1
The sum of all cars will be = 70 + 30 + 50 + 80 + 20 = 250
So,
<span>the probability that’s the nexts car to drive by will be red = (red cars)/(total cars)
= 50 / 250 = 0.2
</span>
the probability that’s the nexts car to drive by will be <span>blue = (</span><span>blue cars)/(total cars) = 70 / 250 = 0.28
then
</span>
<span>the probability that’s the nexts car to drive by will be red or blue
= 0.2 + 0.28 = 0.48 </span>

Answer:
(3x-2y)(3x+2y)
Step-by-step explanation:
Proof:
(3x-2y)(3x+2y)-use FOIL method (First, Outer, Inner, Last)
3x*3x+2y3x-2y3x-2y*2y
9x^2+0-4y^2
<u>9x^2-4y^2</u>
The answer is (3x-2y)(3x+2y).
