Answer: A. 
Step-by-step explanation:
Given : Jason bought 10 of the 30 raffle tickets for a drawing.
i.e. Total tickets = 30
Also, Number of prizes = 3
The total number of combinations of getting 3 prizes out of 30 tickets = 
The number of combinations of getting 3 prizes out of 10 tickets =
Then, the probability that Jason will win all 3 of the prizes if once a raffle ticket wins a prize it is thrown away will be :
Hence, the probability that Jason will win all 3 of the prizes if once a raffle ticket wins a prize it is thrown away is .
Hence, the correct answer is A. 6/203.
Math to me is very complicated. I know that I need it in life, but when have you ever needed to find the square root of the distance from the sun to mars on a normal day-to-day basis? But jokes aside, I know that I do math without thinking about it. It is important, even for the jobs that you would think that you would NEVER need it (even English teachers do it, haha.) Overall, math is kinda iffy. In my opinion, you can't live with it, but you <u>really</u> can't live without it.
To answer, first, convert the given velocity in km/h to m/s as shown below,
(144 km / hr) x (1000 m / 1 km) x (1 hr / 3600 s) = 40 m/s
The acceleration (a) is solved by through the equation,
a = (Vf - Vi) / Δt
where Vf and Vi are final and initial velocities, respectively and Δt is change in time. Substituting the known values,
a = (0 - 40 m/s) / 12 s = -3.3 m/s²
Thus, the answer to this item is letter B.
Answer:
D
Step-by-step explanation:
Rational. Not whole or integer because its an exact measurement and not irrational because it CAN be expressed as a ratio (fraction, decimal measurement )
