Identify two methods a person can use to pay their bills online. Explain the advantages and disadvantages of both methods.

jek_recluse [69]

1) You can pay your bills online using your debit, credit card, or an electronic check. Advantage: you pay when you want and when you are sure you have money in the bank. Disadvantage: you have to remember to pay the bills by the due date.

2) You can set up automatic withdrawal from your bank account to pay your bills. Advantage: once you set it up, you do not have to remember to pay the monthly bills. Disadvantage: if you do not check your checking account balance to be sure there is enough money to cover the bills, your account may go negative.

Hope this helps! :)

What are the related frequencies to the nearest hundredth of the columns of the two way table?

Eddi Din [679]

Answer: The relative frequency of column A in group 1= $0.75$

The relative frequency of column B in group 1= $0.25$

The relative frequency of column A in group 2= $0.56$

The relative frequency of column B in group 2= $0.44$

Step-by-step explanation:

The relative frequency is the ration of each frequency by the total value in particular group.

For group 1 : Total =102+34=136

The relative frequency of column A in group 1= $\frac{102}{136}=0.75$

The relative frequency of column B in group 1= $\frac{34}{136}=0.25$

For group 2 : Total =18+14=32

The relative frequency of column A in group 2= $\frac{18}{32}=0.5625\approx0.56$

The relative frequency of column B in group 2= $\frac{18}{32}=0.4375\approx0.44$
