Answer:
Expected net earning X for this case is 
=$0.6923
Step-by-step explanation:
We need to calculate the probability of the case and multiply by the net earning. The Case is:
<u>the card is a Face card, and the coin lands on Heads</u><u>:</u>
<em>Net earning</em> = 9-3 =6
There are 12 Face Cards in a regular 52-card deck. Then,
<em>Probability of a Face Card</em>= 
<em>Probability that the coin lands on Tails</em> = 
Then <em>total probability of the case</em> is = × =
Expected net earning X for this case is = × 6 =

Step-by-step explanation:
Answer:
3,413.841
Step-by-step explanation:
you times 628.7 by 5.43 and then you get your answer
Formula for compound interest is stated as follows:
A = P(1+r)^n; where A = Amount in the bank after compounding, P = Principal amount deposited in the account, r = annual interest rate as a decimal, n = number of years to accumulate amount A in the account.
Using the values given;
9090 = P(1+0.058)^5
P = 9090/[(1+0.058)^5] = 9090/1.3256 = 6857.02
Therefore, the amount put in the account must be $6,857.02
