An airplane flight has 228 seats. The probability that a person who buys a ticket actually goes on that flight is about 95%. If the airline wants to fill all the seats on the flight, how many tickets should it sell?A. Show your work.

B. Should your answer be more than 228 or less? Explain.

Answers

Answer 1
Answer: there should be 240 tickets sold

I made a proportion by doing 228/95 and equaling it to x/100

x= the number of seats that needs to be sold

I crossed multiplied
and got
95x=228×100

228×100=22800

95x=22800

then I diveded both sides by 95 and got

x=240

hope this helps :)
Answer 2
Answer:

Final answer:

The airline should sell 217 tickets to have a 95% probability that all seats will be filled.

Explanation:

To determine how many tickets the airline should sell, we need to find the number of tickets that corresponds to a 95% probability of a person actually going on the flight. We can think of this as finding the number of tickets that gives us a 95% confidence level.

We can use the formula for confidence interval to find the number of tickets:

Number of tickets = (Desired confidence level) × (Total number of seats)

Number of tickets = 0.95 × 228 = 216.6

Since we can't sell a fraction of a ticket, the airline should sell 217 tickets to have a 95% probability that all seats will be filled.

List the names and corresponding speeds from least to greatest in miles per hour. Julie 62 miles per hour manalo 311,520 feet per hour and leshawn 1,448 meters per minute

Answers

Answer:

\text{Ieshawn's speed}=\frac{53.98 km}{\text{Hour}}, \text{Manalo's speed}=\frac{\text{59 miles}}{\text{hour}}, \text{Julie's speed}=\frac{\text{62 miles}}{\text{hour}}.

Step-by-step explanation:

We have been given 3 different speeds. We are asked to list the names and corresponding speeds from least to greatest in miles per hour.

\text{Julie's speed}=\frac{\text{62 miles}}{\text{hour}}

\text{Manalo's speed}=\frac{\text{311,520 feet}}{\text{hour}}

\text{Manalo's speed}=\frac{\text{311,520 feet}}{\text{hour}}* \frac{\text{1 mile}}{\text{5280 feet}}

\text{Manalo's speed}=\frac{\text{59 miles}}{\text{hour}}

\text{Ieshawn's speed}=\frac{\text{1,448 meters}}{\text{minute}}

\text{Ieshawn's speed}=\frac{\text{1,448 meters}}{\text{minute}}* \frac{\text{60 minutes}}{\text{Hour}}* \frac{\text{1 mile}}{\text{1609.34 meters}}

\text{Ieshawn's speed}=\frac{1,448 *60}{\text{Hour}}* \frac{\text{1 miles}}{1609.34}

\text{Ieshawn's speed}=\frac{86880 miles}{1609.34\text{Hour}}

\text{Ieshawn's speed}=\frac{53.98 miles}{\text{Hour}}

Speeds from least to greatest in miles per hour:

\text{Ieshawn's speed}=\frac{53.98 km}{\text{Hour}},\text{Manalo's speed}=\frac{\text{59 miles}}{\text{hour}}, \text{Julie's speed}=\frac{\text{62 miles}}{\text{hour}}.

If x=2, and y=3, then 40-(9x)+y^2=____

Answers

Answer:

31

Step-by-step explanation:

We need to substitute values of x and y into given formula

40 - (9x) +y² = 40 - (9*2) + 3² = 40 - 18 + 9 = 31

Answer:

40-(9*2)+3^2

= 40 - 18 +9

= 31
