A square storage bin that measures 15 feet on a side is filled with corn. If 1 bushel fits in 1.25 cubic feet, how many bushels
2 answers:
Answer:
2700 bushels
Step-by-step explanation:
First of all we have to calculate the square storage bin volume:
Square storage bin volume= Side*Side*Side
<em>Remember that in a square storage bin (cube) the sides are the same length.</em>
Then:
Square storage bin volume= Side*Side*Side
Square storage bin volume= 15 feet*15 feet*15 feet
Square storage bin volume= 3375
We know that 1 bushel fits in 1.25 cubic feet, then in order to calculate how many bushels the square storage bin contain:
3375 * (1 bushel)/(1.25
)
2700 bushels

Answer:
Step-by-step explanation:
a) Denote the event of commercially availability of f_uel cell technology as F_, commercial availability of solar power technology as S
Write the probability of energy supplied by these energy sources in the next 10 years
P(energy supplied) = P(S ∪ F) -----(1)
Rewrite eqn (1)
P(energy supplied) = P(S) + P(F) - P(F) P(S) ----(2)
substitute 0.85 for P(S) and 0,7 for P(F) in eqn (2) to find the probability of energy supplied by these energy sources
P(energy supplied) = 0.85 + 0.7 - (0.7 * 0.85)
= 0.85 + 0.7 - (0.595)
= 1.55 - 0.595
= 0.955
Therefore, the probability that there will be energy supplied by these two alternative sources in the next 10 years is 0.955
B) write the probability of only one source of energy available
P(only one source of energy available) = ∪
---(3)
Rewrite the equation (3)
P(only one source of energy available) =
Therefore,The probability that only one of the two alternative energy sources will be commercially viable in the next 10 years is 0.36
