Answer:

economy class = 260

business class = 100.

Step-by-step explanation:

for every 13 economy seats, there are 5 business class seats

EC = 13

BC = 5

ADD to get total = 18

divide 360 by 18 to get the number of groups created.

you get 20.

multiply 20 by each class seats

13 by 20 = 260

5 by 20 = 100

you can confirm by adding the seats to see if you will get 360.

You get a bagel for $1.95 and juice for $1.09 . You pay with a 5 -dollar bill. How much change will you get back?

inessss [21]

1.95 + 1.09 = 3.04 so you will spend $3.04 then 5 - 3.04 = $1.96

Rainbow [258]

Answer:

(A) 0.006593 or 0.6593%

(B) 0.01538 or 1.538%

Step-by-step explanation:

The total number of possibilities to pick 3 parts out of 15 possible parts is given by the following combination:

$n=\frac{15!}{(15-3)!3!}=\frac{15*14*13}{3*2*1}\\n=455\ ways\\$

(A) There are only three possibilities for which the inspector finds exactly one nonconforming part (NCC, CNC, CCN). Therefore, the probability is:

$P(N=1) = \frac{3}{455}=0.006593 =0.6593\%$

(B) There are three possibilities for which the inspector finds exactly one nonconforming part, three possibilities for two nonconforming parts (NNC, CNN, NCN), and one possibility for all nonconforming parts (NNN). The probability that the inspector finds at least one nonconforming part is:

$P(N>0) =P(N=1)+P(N=2)+P(N=3) \\P(N>0) = \frac{3}{455}+ \frac{3}{455}+ \frac{1}{455}\\P(N>0) =0.01538 =1.538\%$
