The total snowfall per year in Laytonville is normally distributed with mean 99 inches and standard deviation 14 inches. Based o n the Empirical Rule, what is the probability that in a randomly selected year, the snowfall was less than 127 inches
1 answer:
Answer: Required probability is 0.9772.
Step-by-step explanation:
Since we have given that
Mean = 99 inches
Standard deviation = 14 inches
It is normally distributed.
We need to find the probability that in a randomly selected year, the snowfall was less than 127 inches.
As we know that
So, it becomes,
Hence, required probability is 0.9772.

I believe the answer is D. 25 and 27
it equals -1
you can think of it as 7-6=1 and at the end you can just add the negative sign
Hope it helps :))
I think there's supposed to be a picture here. Anyway, you can find out by finding the slope of the line on the graph and comparing it to .5 which is Henry's slope. If the graphed slope is larger than .5 then Clark hikes faster, if it is less than .5, Henry hikes faster.
Hope this helps :)
