In post-apocalyptic neverland, clean water is sold in "2-liter" bottles off the back of a truck that arrives every day. the arrival time is normally distributed with mean 2: 54 pm and standard deviation 24 minutes. the time it takes for the water to sell out is also normally distributed with mean 33 minutes and standard deviation 7 minutes. the price of a "2-liter" bottle fluctuates from day to day according to a normal distribution with mean 128 rubles and standard deviation 4 rubles. the amount of water in a "2-liter" bottle varies from bottle to bottle according to a normal distribution with mean 63.5 ounces and standard deviation 1 ounce. assume that all days, all times, and all bottles are independent.

on april 3, 2020, you buy four "2-liter" bottles of clean water. what is the probability that it costs you more than 500 rubles? give your answer to 4 decimal places.

0.7734

Step-by-step explanation:

The average in this problem is 128 and the standard deviation is 4.

We buy 4 bottles.  We want the probability that the cost is more than 500 rubles; this means the average of each bottle would be

500/4 = 125 rubles.  This is our X value.

Using the z score formula, we have

Using a z table, the area under the curve less than this is 0.2266.  We want the probability that the cost is more than this, which would be to the right; we subtract from 1:

1-0.2266 = 0.7734

the answer is thin because within context, the stanza concludes the and frail tone the people have toward each other, and the fact that it would be thin, makes the most sense compared to "pliable" or "not hard or firm to the touch". hope this , good luck.

can i have brainliest

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
