Answer:

A.10

B.10

C. 10,000

D. 8 hours

Step-by-step explanation:

Firstly, we should know that the numbers are labeled 0-9.

A. 10 digits

B. We already took one digit , but we still have 10 choices left again as numbers can be repeated.

C. For the first number, we have 10C1 choices since we are selecting 1 out of 10 numbers. This is the case for all the 3 renaming numbers. Hence the total number of possible passwords are

(10C1)^4 = 10,000 possible password combinations

D. That is (10,000*3)/60 in minutes = 500 minutes = 500/60 = 8.3333 , approximately 8hrs

Neil and Nancy are married with two children at home and a mortgage. Neil's net pay per year is $56,000 and Nancy doesn't have a
jok3333 [9.3K]

Answer:

their current cash flow is negative since their expenses are higher than their income:

  • monthly net income = $56,000 / 12 = $4,667
  • monthly expenses = $1,500 + $3,500 = $5,000
  • monthly cash flow = ($333)

they have 3 options:

  • Option 1 (which I personally dislike) is that Neil contributes $4,000 less per year to his retirement account in order to balance their net income and expenses. The problem is that once he retires, his income will be much lower.
  • Option 2 is that they lower their expenses a little bit, only enough to balance their cash flows.
  • Option 3 is that Nancy gets a part time job, maybe a couple of hours per day which will allow her to earn money that can be used to cover some expenses.

Personally I believe that option 2 is the best, but if they definitely cannot lower their monthly expenses, then option 3 would probably fit them.
