<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>
The answer it Curve Fitting or Arc but I think Curve Fitting just good luck
3n+4=-5
do the opposite of adding 4. this means you have to subtract 4 from 4. whatever you do to the problem, you must do to the answer. now subtract 4 from -5.
-5-4=-9
since 4-4=0, we can take 4 out of the equation. now you have:
3n=-9
now divide -9 by 3
-9/3=-3
n=-3
hope this helps :)
Answer:
D
Step-by-step explanation:
The line can be named with small latin letters or with two large latin letters which represent two points lying on the line.
Consider all options:
A. Points V and X lie on the line, so you can name the line as VX (true option)
B. Points W and X lie on the line, so you can name the line as WX (true option)
C. p represents the line (small letter given on the diagram) - (true option)
D. You cannot name the line using point V and line p, so this option is false
Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.
Matt's steps will be more complicated since Annie is using a program to do the constructions hers would probably be precise and easy.
