I believe you would take 127.5 and divide it by 8.5, try that and see if that works, hope this helps!
Answer:
With what?
Step-by-step explanation:
Oof, this is surely a tough one. But, if I'm looking at this correctly, than I think you were in the right mindset when trying to figure both of them out. Like, for #18, think about the formula; P(B|A) = P(A and B)/P(A). So, based on the question, you can let not rolling a 1 on the blue cube be A, and rolling a 1 on the red cube be B. Now, personally, I prefer using the decimals when heading into the equations, but I'll convert the product into a fraction for the instruction's sake. 0.02777777778 + 0.13888888889 = 1/6. 1/6 ≈ 17.7%. You can do the same for #19, the overall outcome would be 5/6, which would be about 83%. Now, that's just me really attempting my hand at it, I will say, Math is far from my strong suite. But, in all honesty, I really am doing my best to help (and no, it's not because of what you offered, lol, more rather I want to help people who struggle with the same problems I do). Anyways, I hope this helps, and if you need more information, or anything, just let me know! Wish ya the best of luck!! ^u^
Answer:
read the problem
Step-by-step explanation:
a. write down the facts and figures
b. read the problem
c. find a relationship between what is given and what must be found
d. do the work
Answer:
Step-by-step explanation:
d = r * t Divide both sides by t
r = d / t
d = distance = 2.25 km
t = time = 3 3/4 minutes = 3.75 minutes
r = 2.25 / 3.75
r = 0.6 km / minute
r = 3/5 km / minute
If the units are different than those given, please state them underneath my answer. I'll get to it as soon as I see your comment.
