For the polynomial 8x3y2 – x?y2 + 3xy2 – 4y3 to be fully simplified and written in standard form, the missing exponent on the x-term must be

Answers

Answer 1
Answer: In writing the standard form, the order of the exponents of the terms must be decreasing from left to right. Looking at the first term on the left, the exponent of x is 3. Looking at the third term from the left, the exponent of x is 1. Therefore, the missing exponent on the x-term must be 2.
Answer 2
Answer:

Short answer: 2

Why?

The missing x term is between an exponent of 3 and 1. Because this is standard form, we put the biggest exponent first and then go down the list. Therefore, it must be 2.

Good luck!

A game has 3 possible outcomes, with probabilities p1, p2, and p3. The amount of money that you will win or lose for each outcome is v1, v2, and v3, respectively. What is the expression p1v1 + p2v2 + p3v3 equal to?

Answers

We have the following given
p1 - probability for outcome 1
p2 - probability for outcome 2
p3 - probability for outcome 3
v1 - amount of money that you will win or lose for outcome 1
v2 - amount of money that you will win or lose for outcome 2
v3 - amount of money that you will win or lose for outcome 3

Therefore,
p1v1 + p2v2 + p3v3 is the average money you win or lose in playing the game.

Answer:

Option b) The average amount you will win (or lose) per game in the long run

Step-by-step explanation:

You owe $1,000 on a credit card that has an interest rate of 27.99% and make only the minimum payment of $20 each month. Which answer is correct?A. You will have the card paid off within a year.
B. You will never have the credit card paid off.
C. You will have it paid off within 5 years.
D. You will have the credit card paid off within 10 years.

Answers

Answer: The credit card will paid off within 10 years, therefore the correct option is D.

Explanation:

Let the number of years in which the credit card will aid of be x.

It is given that amount owed on credit card is $1000 with interest rate 27.99%.

So the amount of interest is calculated as,

1000* (27.99)/(100) =\$27.9

The total amount have to pay is,

\$1000+\$279.9=\$1279.9

The minimum payment is $20 each month.

x=(1279.9)/(20)

x=63.995

So, the credit card will paid of in 63.995 months. We know that 1 year =12 months.

(63.995)/(12) =5.33

Therefore, the will paid of in 5.33 years, s we can say that the credit card will paid off within 10 years, therefore the correct option is D.

Final answer:

The correct answer is not listed; it would take significantly longer than 10 years to pay off a $1,000 credit card debt at 27.99% APR by making only $20 minimum payments due to the high interest rate.

Explanation:

When dealing with credit card debt, it is crucial to understand the impact of making only minimum payments, especially when the interest rate is high. In the example provided, a credit card balance of $1,000 with an annual percentage rate (APR) of 27.99% and a minimum payment of $20 per month would take much longer than any of the given options to pay off if one were to only make minimum payments. Calculations using a debt repayment calculator or an amortization formula would show that the option of paying it off within 1, 5, or even 10 years by making minimum payments only is not feasible due to the high-interest costs that add up each month. The correct answer would be similar to the situation in which it takes about 15 years to pay off a $2,000 debt, making minimum payments will eventually lead to a payoff, but with a larger cost in interest over time.

When I was 2 years old, my sister was half of my age. Now Im 80 years old, how old is my sister?

Answers

Half of 2 = 1 so 1 year apart . That means 

80-1 = 79 years 
if u were 2 years old n your sister was half your age then her age must be 1
so her present age is 80-1=79(since she was just one year smaller than u)
