M/5 + 3(m - 1) = 2(m - 3)

Simplify inside the parenthesis.

m/5 + 3m - 3 = 2m - 6

Now, we need to move all variables to the left side of the equal sign, and move all isolated numbers to the other (right) side of the equal sign.

So, we need to add 3 to both sides, and subtract 2m from both sides,

m/5 + 3m - 2m = -6 + 3

Simplify.

m/5 + m = -3

Remember : m/5 is basically 1/5m :)

So, our equation now looks like this :

1/5m + m = -3

Remember, "m" is basically 5/5, because "5" is our common denominator.

So, our equation now looks like this :

1/5m + 5/5m = -3

Simplify.

6/5m = -3

Then, multiply both sides by 5/6 so that m is isolated.

5/6 × 6/5m = -3 × 5/6

Simplify.

m = -5/2 AND -2 1/2 AND -2.5

Statistics show that about 42% of Americans voted in the previous national election. If three Americans are randomly selected, w

Answer:

19.51% probability that none of them voted in the last election

Step-by-step explanation:

For each American, there are only two possible outcomes. Either they voted in the previous national election, or they did not. The probability of an American voting in the previous election is independent of other Americans. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$
