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 will check each options
option-A:
The modulus represents the distance between the complex number and the origin
we know that modulus is a kind of distance
For example: if we have to find modulus of x+iy
we get
that is also distance between (0,0) and (x,y)
so, this is TRUE
option-B:
It is also similar to Pythagoras theorem
so, this is also TRUE
option-C:
we got modulus formula
we know that value of sqrt can never be negative because it will always result in positive value
so, this is FALSE
option-D:
It is also similar to absolute value
so, this is TRUE
