Answer:
Step-by-step explanation:
2/3 means 2 out of 3 parts
to find out the 3 parts of 6 you do 6 divided by 3 to get 2
1 part is 2
2/3 means 2 out of 3 parts so you need to find the 2 parts
since 1 part is 2 then 2 parts are 2x2=4
Answer:
3
17
Step-by-step explanation:
3 groups of 17 are the only way to divide 51 evenly.
3 x 17 = 51 + 1 = 52

27ft³=x tons
1ft³=0.5 tons

Cross multiply
1x=13.5tons
x=13.5tons
So one scoop/load carries 13.5 tons of sand. Lets see how many 120 loads can carry.
13.5tons*120loads=1620 tons of sand
Now lets see how freight cars it would take to hold 1620 tons of sand
1620/40=40.5 freight cars
Since you can't have .5 of a freight car, lets round 40.5 up to 41
Answer=41 freight cars
Answer:
Here, we have:
P(5 days snow in this 8 days) = 8C5 x (0.85)^5 x (1 - 0.85)^3 = 0.084
P(6 days snow in this 8 days) = 8C6 x (0.85)^6 x (1 - 0.85)^2 = 0.238
P(7 days snow in this 8 days) = 8C7 x (0.85)^7 x (1 - 0.85)^1 = 0.385
P(8 days snow in this 8 days) = 8C8 x (0.85)^8 x (1 - 0.85)^0 = 0.272
Add up those above, then the probability that it will snow AT LEAST five of those days in February:
P = 0.084+ 0.238 + 0. 385 + 0.272 = 0.979
Hope this helps!
