Answer:
Total # of marbles: 10
# of red marbles: 7
Probability of choosing a red marble out of 10 marbles: 7/10
Then in the second round, you replace that marble so you still have a total of 10 marbles and 7 of them will still be red: 7/10
Multiply...
7/10 x 7/10 = 49/100
PROBABILITY: 49/100 (or 49%)

Answer:
Reserve rate = 9%
Step-by-step explanation:
Reserve ratio/rate is the percentage of deposits which commercial banks are required to keep as cash, as directed by the central banks.
first, let us calculate the reserve amount as follows:
Reserve = Deposit - (free amount to lend out)
Reserve = 28,000 - 25,480 = $2,520
![Reserve\ rate = \frac{Reserves}{Deposits} \times100\\Reserve\ rate = \frac{2520}{28000} \times100\\=\frac{252000}{28000} =9\%](https://tex.z-dn.net/?f=Reserve%5C%20rate%20%3D%20%5Cfrac%7BReserves%7D%7BDeposits%7D%20%5Ctimes100%5C%5CReserve%5C%20rate%20%3D%20%5Cfrac%7B2520%7D%7B28000%7D%20%5Ctimes100%5C%5C%3D%5Cfrac%7B252000%7D%7B28000%7D%20%3D9%5C%25)
Therefore the reserve rate = 9%

Answer:
Yes.
Step-by-step explanation:
Any number raised to the power of 2 will be greater than the original number.
A positive number:
4² = 16
A negative number:
-3² = 9
Or:
0² = 0
