So, first you divide 75000 by 1000. Then you add 2 to each side. Then that's the answer, x=77
Use the substitution method for y=0
(40,0)
y=0
0=0
Answer: (40,0) It does make the equation y=0 true
<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>
Answer:
40%
Step-by-step explanation:
It is 40% because 8/20 times 5 is 40/100 and that is 40%.
