<span>3 of the 20 toothbrushes are defective, so the initial probability of selecting a defective toothbrush on the first try is 3/20. After that, there will be 2 defective toothbrushes in the remaining 19, so the probability of selecting one of those on the 2nd try will be 2/19. To get the probability of those two events happening sequentially, we multiply the two probabilities. Thus (3/20)*(2/19) = 6/380 = 0.0157, or about 1.6%.</span>
6+(4/5)
=(30/5)+(4/5)
=34/5
Answer:
y= -1/3x - 2/3
Step-by-step explanation:
y- intercept is (0, -2/3) and the x intercept is (0, -2).
To find the slope of an equation, you do rise over run. To get from (0, -2/3) to (0, -2), you rise 2/3 and run -2. 2/3 divided by -2 is -1/3, that is where you get the slope from.
Answer:
2340
Step-by-step explanation:
(-12)×(13)×(-15)
=(-156)×(-15)[ (+) × (-) = (-)]
=2340[(-) × (-) = (+)]
