Answer: About 99.74% of births would be expected to occur within 24 days of the mean pregnancy length.
Step-by-step explanation:
Complete question is attached below.
Given: The lengths of pregnancy terms for a particular species of mammal are nearly normally distributed about a mean pregnancy length with a standard deviation of 8 days.
i.e.
let X denotes the random variable that represents the lengths of pregnancy.
The probability of births would be expected to occur within 24 days of the mean pregnancy length:
=99.74%
Hence, about 99.74% of births would be expected to occur within 24 days of the mean pregnancy length.
Answer:
25
Step-by-step explanation:
Segment XY = 10
Segment XZ = 15
Since the lenght of segment WX is said to be congruent to the lenght of segment XY, therefore:
WX = XY = 10
Segment WX + Segment XZ = Segment WZ (segment addition postulate)
(substitution)
Length of segment WX = 25
