Answer: D. an angle is in standard position if the vertex is at the origin of a rectangular coordinate system and the initial side lies along the positive x-axis.
Answer:
(221.39, 300.61) and (255.2223, 266.7777)
Step-by-step explanation:
Given that X, the lengths of pregnancies in a small rural village are normally distributed with a mean of 261 days and a standard deviation of 17 days
Middle 98% would lie on either side of the mean with probability ±2.33 in the std normal distribution on either side of 0
Corresponding we have x scores as
Between
and 
i.e. in the interval = (221.39, 300.61)
If sample size = 47, then std error of sample would be

So 98% of pregnancies would lie between
and 
= (255.2223, 266.7777)
Answer:
1
Step-by-step explanation:
Answer:
Range = highest value - lowest value
Explanation:
This is the required formula to find range from a distribution table.
Two sides are the same length one angle measures 90 degrees
