The annual precipitation amounts in a certain mountain range are normally distributed with a mean of 8080 inches, and a standard deviation of 1616 inches. what is the probability that the mean annual precipitation during 6464 randomly picked years will be less than 82.882.8 inches? round your answer to four decimal places.

The sample mean is μ=80, and sample standard deviation is σₓ=.

The Z-score is .

Refer to standard normal distribution table.

The required probability is

if you mean

then it's c. 8, -7/3

but if you mean

then it is

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
