Step-by-step explanation:

x+y=60

400x+250y=18600

x=60-y

400(60-y)+250y=18600

y=36.

solve this expression then u will get the answer for y.

In response to the increasing weight of airline passengers, the Federal Aviation Administration in 2003 told airlines to assume

Rufina [12.5K]

Answer:

The approximate probability that the total weight of the passengers exceeds 4432 pounds is 0.2709

Step-by-step explanation:

$\mu = 192$

$\sigma = 31$

No. of passengers = n = 21

We are supposed to find the approximate probability that the total weight of the passengers exceeds 4432 pounds

$x = \frac{4432}{21} \sim 211$

$Z=\frac{x-\mu}{\sigma}\\Z=\frac{211-192}{31}$

Z=0.612

refer z table

P(Z<211)=0.7291

P(Z>211)=P(Z>4432)=1-0.7291=0.2709

Hence the approximate probability that the total weight of the passengers exceeds 4432 pounds is 0.2709
