The recipe makes 8 pancakes.
He wants to make 12 pancakes.

First, find out how many times what he needs is compared to the recipe.

He wants 12 pancakes; the recipe makes 8 pancakes.

12/8 = 1.5

He wants to make 1.5 times the recipe.

Now multiply every ingredient amount by 1.5 to find what he needs to make 12 pancakes.

240 g of plain flour.
240 g * 1.5 = 360 g of plain flour

2 egs
2 eggs * 1.5 = 3 eggs

600 ml milk
600 ml * 1.5 = 900 ml

Answer: 360; 3; 900

A kitten was given to a child as a birthday present when she was two years old. The cat lived a good life, but eventually became

Katyanochek1 [597]

Answer: 14 years

Step-by-step explanation:

Let the cat's age when it died = x.

Therefore, the child's age is 2 + x because he/she got the cat when he/she was 2 years old.

We can set up an equation.

x + (2+x) = 30

2x + 2 = 30

2x = 28

Therefore, x = 14

When someone buys a ticket for an airline flight, there is a 0.098 probability that the person will not show up for the flight.

DedPeter [7]

Answer:

Step-by-step explanation:

Probability that a person will not show up is,

P(person not show up)=0.098.

Probability that they will show up is

1-0.098=0.902

P(person will show up)=0.902

Jet passenger seat=18.

a. But is it wise to book 20 passenger seat

If the flight attendant book 20.

We want to know the probability that the two person will not show up.

The probability that the 2 person will not show up out of the 20 is given as

Using binomial distribution

Check attachment for formulas.

P(2 not showing up) =

20C2 • 0.098² • 0.902^20=0.2319

Which is 23.19% that the 2 person will not show up.

b. But is it wise to book 24 passengers for 22 jet seat.

The probability that the 2 will not show up out of the 24 is given as

Using binomial distribution

P(2 not showing up) =

24C2 • 0.098²• 0.902²²=0.2741

Which is 27.41% that the four person will not show up.

c. Probability of no enough seat

For 20 passengers and 18seats on jet

1-0.2319=0.7631.

For 24 passengers and 20 seats on jet

1-27.41=0.7259.

Then, It is not a wise decision because the probability that there are not enough seats on the jet is 0.7259 (72.59%). So, overbooking is an unlikely event.
