Answer:
1st statement is true.
2nd statement is false.
3rd statement is true.
Step-by-step explanation:
We have been given two inequalities and we are asked to find out whether the given statements are true or false.
represents balance of account A and represents balance of account B.
1. We can see from our inequalities that Jeremiah initially invested $100 in account A and $50 in account B. Therefore, 1st statement is true.
2. The rate at which balance of account A grows is 1.2 and rate for account B is 1.23. Therefore, 2nd statement is false.
3. We can find total amount Jeremiah invested in two accounts by adding initial investment of both accounts, that is 100+50=150 . Therefore, 3rd statement is true.
The answer is b because 0.008 is negative and is being subtracted from 2.9.

0.5 40 60
Answer:
Expected values for x and Y
E(x) = 39, E(Y) = 61
Variance for x and Y
E(x^2) = 1570
E(Y^2) =3830

Let W and J represent the # of votes rec'd by Will and John. Then J = 2W.
Then W + J = 36, and W + 2W = 36 => 3W = 36 => W = 12.
Will rec'd 12 votes and John rec'd 2(12), or 24, votes.
Note that 12 + 24 = 36.
