Third and last.
first, second and forth are wrong
Answer:
- the sample mean is 44
- the sample standard deviation is 12.35
Step-by-step explanation:
given information:
data, 
= 36.45, 67.90, 38.77, 42.18, 26.72, 50.77, 39.0, 50.23
the number of data, n = 8
the sample mean, xbar
xbar = ∑/n
= (36.45+67.90+38.77+42.18+26.72+50.77+39.0+50.23)/8
= 352.08/8
= 44
standard deviation, s
s = 
= 
= 
= 12.35
Answer:
depending on the form of how your question is actually written .. The answer will either be :
x= -1
or
There are no values of x that make the equation true. No solution.
Step-by-step explanation:
Hope this helps
You can use your calculator if you have one or do long division. just make sure to move the decimal so it looks like this: 63 divided by 7. you answer should be 9
