Global Airlines operates two types of jet planes: jumbo and ordinary. On jumbo jets, 25% of the passengers are on business while

MArishka [77]

Answer:

The probability is $P(J|B) = 0.36$

Step-by-step explanation:

B =business

J=jumbo

Or =ordinary

From the question we are told that

The proportion of the passenger on business in the ordinary jet is $P(B| Or) = 0.25$

The proportion of the passenger on business in the jumbo jet is $P(B|J) = 0.30$

The proportion of the passenger on jumbo jets is $P(j) = 0.40$

The proportion of the passenger on ordinary jets is evaluated as

$1 - P(J) = 1- 0.40 = 0.60$

According to Bayer's theorem the probability a randomly chosen business customer flying with Global is on a jumbo jet is mathematically represented as

$P(J|B) = \frac{P(J) * P(B|J)}{P(J ) * P(B|J) + P(Or ) * P(B|Or)}$

substituting values

$P(J|B) = \frac{ 0.4 * 0.25}{0.4 * 0.25 + 0.6 * 0.3}$

$P(J|B) = 0.36$

Lolita deposited 500 in her savings account that earns 5% intrest compounded anually. She forgot about it until now, 15 years la

Sonja [21]

Answer:

P = 1039.5

Step-by-step explanation:

Given:-

- The initial amount deposited, Po = 500

- The interest rate applied, I = 5% compounded annually

Find:-

- The amount on her bank statement after 15 years?

Solution:-

- We see that the principal amount increases every year and no transactions have been made in the course of 15 years.

The total amount left in her savings account would be given by the following formula:

P = Po * ( 1 + I/100 )^n

- Where, n = number of years passed since deposit. (15 years)

P = 500 * ( 1 + 5/100 )^15

P = 500 * (1.05)^15

P = 1039.5

almond37 [142]

Answer:

The volume of the marble is 47 ml

The volume of the water is 100 ml

Step-by-step explanation:

we know that

The volume of the marble is equal to the change in water level

To find out the volume of the marble subtract 100 ml from 147 ml

$147-100=47\ ml$

The volume of the water no change

The volume of the water is 100 ml

2 1/2 x 3 1/5 fast please

vova2212 [387]

Step-by-step explanation:

Let's turn each mixed fraction into an improper fraction:

$2 \frac{1}{2} =\frac{2}{2} +\frac{2}{2} +\frac{1}{2} =\frac{5}{2}$

$3\frac{1}{5} =\frac{5}{5} +\frac{5}{5} +\frac{5}{5} +\frac{1}{5} =\frac{16}{5}$

Multiply:

$\frac{5}{2} \times \frac{16}{5} =\frac{80}{10}$

Simplify:

$\frac{80 \div 10}{10 \div 10} =\frac{8}{1} =8$

8 is your simplified product.
