Answer:
I have that same problem but im trying to figure out the answer
Step-by-step explanation:
According to the problem we start with 6000 gal of E10 which means there is 10% of ethanol in this 6000, with ths information we can calculate the amount of ethanol already in the mixture:
The relationship between ethanol and total fluid can be represented like this:
Based on this relationship we can build the one that we are looking for:
the total solution will be:
where X is the E5 solution volume
and the TotalEthanol would be:
where E5ethanol (5% Ethanol 95% Gasoline) would be:
Now replacing in the relationship we found before:
Solving for X:
We should mix 1500 gal of E5 to make an E9 mixture
Answer:
The probability of selecting at least one consonant when selecting 2 cards is 0.0954.
Step-by-step explanation:
There are 26 letters in the English alphabet series.
Of these 26 letters there are 5 vowels and 21 consonants.
The total number of ways to select 2 letters is:
The number of ways to select at least one consonant is:
n (At least 1 consonant) = N - n (Two vowels)
Compute the probability of selecting at least one consonant as follows:
Thus, the probability of selecting at least one consonant when selecting 2 cards is 0.0954.
