Tickets for an upcoming concert are sold out but a local charity is having a raffle and the prize is a pair of tickets to the concert. One hundred people enter the raffle, so each individual who entered has 1/100 probability of winning the pair of tickets. You and a friend both entered. What is the probability that one or the other of you wins the tickets

Answers

Answer:

[tex]P(A\ or\ B) = \frac{1}{50}[/tex]

Step-by-step explanation:

Represent the event that you win with A and the even that your friend win with B.

So, we have:

[tex]P(A) = \frac{1}{100}[/tex]

[tex]P(B) = \frac{1}{100}[/tex]

Required

Calculate P(A or B)

Both events are mutually exclusive.

So:

[tex]P(A\ or\ B) = P(A) + P(B)[/tex]

Substitute values for P(A) and P(B)

[tex]P(A\ or\ B) = \frac{1}{100} + \frac{1}{100}[/tex]

Take LCM

[tex]P(A\ or\ B) = \frac{1+1}{100}[/tex]

[tex]P(A\ or\ B) = \frac{2}{100}[/tex]

Simplify:

[tex]P(A\ or\ B) = \frac{1}{50}[/tex]

There are 9 students in the art club. The students shared 150 sheets of construction paper equally for an art project. How many sheets of paper were left over?

Answers

Answer: 6 sheets left over.

Step-by-step explanation:

Given, Total students = 9

Total sheets = 150

If sheets were divided equally, then the number of sheets each student got = Total sheets ÷ Total students

= 150 ÷ 9

[tex]= 16\dfrac{6}{9}[/tex]

So, each student got 16 sheets and 6 sheets left over.

Hence, 6 sheets were left over.

Compute 292,000 divide 100.

Answers

I think The answer is 2920

The division 292,000 divide 100. results to 2920.

What is Division?

Repetitive subtraction is the process of division. It is the multiplication operation's opposite. It is described as the process of creating equitable groups. When dividing numbers, we divide a larger number down into smaller ones such that the larger number obtained will be equal to the multiplication of the smaller numbers.

Given:

292,000 divide 100.

We know division with zero in the denominator is different and easy.

As, 292000 have three and 100 have two zeroes.

So, the two zero of hundred cancels out the two zeroes of  292000.

So, 292000/ 100

= 2920

Hence, the division results to 2920.

The difference between two numbers is 2.5 . The product of those two numbers is 21. Provide the 2 equations needed to solve the application separated by a comma and NO SPACES.

Answers

Answer:

x-y=2.5,xy=21

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

One of the numbers is x.

The other number is y.

The difference between two numbers is 2.5

This means that x - y = 2.5

The product of those two numbers is 21.

This means that xy = 21.

So the two equations are: x-y=2.5,xy=21

Which of these transaction types

DECREASE how much you owe the credit card

company?

Answers

Options:

a. Balance Transfers

b. Cash Advances

c. Payments

d. Interest Charges

Answer:

c. Payments

Step-by-step explanation:

Of all the given options, only (c) Payments decreases amount owed.

(a) Balance transfer means one is taking out cash from the account (i.e. a debit transaction); (b) Cash advances implies a withdrawal transaction from one's account and (c) Interest charges is the amount of interest deducted from an account over a debt for a given period.

As analysed , each of the above transactions increases debts.

However, (c) Payments implies a credit transaction and as such, reduces the amount owed.

The only transaction type among the given ones that helps to decrease how much you owe the credit card company is;

Option C; Payments

The missing options are;

A) Balance Transfers

B) Cash Advances

C) Payments

D) Interest Charged

We want to find out which of the transactions among the given options would lead to a decrease in the amount you owe the credit card company.

Let's analyze the options;

Option A; Balance transfer means when a customer wants to move the amount he/she owns to a credit card that has lower interest rates. This does not reduce the debts as the debts are still there just that you have moved the funds to another credit card.

Option B; Cash advances are typically short term loans offered the credit card company. Thus, it only increases your debt.

Option C; Payments in this case means paying outstanding debts with the credit card holder. Thus, it helps to decrease how much you owe the credit card company.

Option D; Interest charges are usually the amount issued by the credit card holder for debts accrued over a given period of time.

Looking at the options, the only one that helps to decrease how much you owe the credit card company is Option C.
