The total snowfall per year in Laytonville is normally distributed with mean 99 inches and standard deviation 14 inches. Based o
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.

Answer:
A = 20.5 sq units
Step-by-step explanation:
you have the height of 5 but need to figure out the base
we can use the Pythagorean Theorem two times to find it
1) a² + 5² = 7²
a² = 49-25
a = =
·
= 2
2) b² + 5² = 6²
b² = 36-25
b =
Base = 2 +
A = 1/2 x 5· (2 +
)
A = 2.5 · (2 +
)
A = 2.5(8.2)
A = 20.5
Switch sides:
find least common multiplier of 16, 4
Prime factorization of 16 = 4²
Prime factorization of 4 = 2²
LCM = 16
Multiply by LCM
