Answer:
4083.2
Step-by-step explanation:
I don't know if I'm right Y=10
Given steps :
Step 1: m∠m + m∠n + m∠o = 180 degrees (sum of angles of a triangle)
Step 2: m∠p − m∠o = 90 degrees (alternate interior angles) : <em>It's incorrect step because m<p and m<0 are on a common point on a line and make a linear pair. Therefore, m<p and m<0 are supplementary angles.</em>
Step 3: Therefore, m∠m + m∠n + m∠o = m∠o + m∠p.
Step 4: So, m∠m + m∠n = m∠p.
<h3>Therefore, student did mistake in 2nd step and correct step should be Step 2; it should be m∠o + m∠p = 180 degrees (supplementary angles).</h3>
Yes, a common denominator is just the smallest multiple of all numbers in a group.
So the common denominator of 4, 8 and 12 would be 4, because 4 goes into all those numbers.
Answer:
sigma should be used
Step-by-step explanation:
Given that The mean length of time in jail from the survey was four years with a standard deviation of 1.9 years.
The above given is for sample of 27 size.
For hypothesis test to compare mean of sample with population we can use either population std dev or sample std dev.
But once population std deviation is given, we use only that as that would be more reliable.
So here we can use population std deviation 1.4 only.
If population std deviation is used we can use normality and do Z test
