Answer:
for sample = xbar
population = μ
Step-by-step explanation:
The arithmetic mean for sample can be represented by xbar and it can be calculated as
xbar=∑xi/n
Where xi represents data values and n represents number of data values in a sample.
The arithmetic mean for population can be represented by μ and it can be calculated as
μ=∑xi/N
Where xi represents data values and N represents number of data values in a population.
Answer:b
8
You just gotta divide 64 by 8
40. m∠2=148° m∠4=148°
41. ∠2 and ∠5
42. ∠1 and ∠2
43. ∠3 and ∠5
Sorry, I don't know how to do the rest, but I hope this helps!
