The reciprocal of
Answer:
0%
Step-by-step explanation:
We have the following information:
mean (m) = 208 days
standard deviation (s) = 15 days
We have that the z value would be:
z = (x - m) / sd
replacing we have:
z = (308 - 208) / 15
z = 6.66
However,
P (x> 308) = 1 - (x <308)
P (x> 308) = 1 - (z <6.66)
if we look for this value of z in the table we assume that it is 1, since the table reaches 3 and the value is 1. Therefore:
P (x> 308) = 1 - 1
P (x> 308) = 0
Which means that the probability is 0%, therefore it is a very unusual pregnancy.

We can use Pythagorean theorem to find lenght of each wire.
x^2 = 16^2 + 12^2
x^2 = 256 + 144
x^2 = 400
x = 20
Lenght of one wire is 20
Hence lenght of two wires would be 20 * 2 = 40 feet : Answer
Hope it will help you :)
