What is the probability of rolling a six on a fair die?

Answers

Answer: 1/6

Step-by-step explanation: To find the probability of rolling a six,

let's use our ratio for the probability of an event.

number of favorable outcomes / total number of outcomes

Since only one side of a die has a six on on it, the number of favorable

outcomes for rolling a six is 1 and since there are six sides to a die and it's

equally likely that the die will landy on any of these sides, the total number

of outcomes is 6.

So the probability of rolling a six is 1/6.

The relation is the descending the series by 7 and the next term is 33.

We have to determine, find the pattern and what numbers come next

We have given that, 61, 54, 47, 40.

What is the series?

A series is, roughly speaking, a description of the operation of adding infinitely many quantities, one after the other.

61-54=7

54-47=7

47-40=7

So the next term is

40-7=33

Therefore the relation is the descending the series by 7 and the next term is 33.

The seventh-grade class is putting on a variety show to raise money. It costs $150 to rent the auditorium that they are going to use. If they charge $5 per ticket, how many tickets do they need to see in order to raise at least $750?

Answers

Answer:

180 tickets

Step-by-step explanation:

750 + 150 = 900 they will have to make

900/5 = 180 tickets

To raise at least $750, the seventh-grade class needs to sell a minimum of 180 tickets, priced at $5 each, to cover the fundraising goal and the $150 auditorium rental cost.

Given that,

Seventh-grade class is putting on a variety show to raise money.

The auditorium rental cost is $150.

Each ticket is priced at $5.

The goal is to raise at least $750.

Denote the number of tickets they need to sell as "x".

The revenue generated from ticket sales can be calculated by multiplying the number of tickets sold (x) by the ticket price ($5),

Which gives us 5x dollars.

Now since,

Total revenue from ticket sales - Auditorium rental cost ≥ Fundraising goal

Therefore,

5x - 150 ≥ 750

Add 150 to both sides:

5x ≥ 900

Divide both sides by 5 to solve for x:

x ≥ 180

Since the seventh-grade class cannot sell a fractional number of tickets,

Hence,

They need to sell at least 180 tickets to raise at least $750 and cover the auditorium rental cost.
