Description statistics is used to summarize sample or population by determining some of its parameters like mean, variance, standard deviation, proportion etc.
Stacy Wood at the Moore School of Business in South Carolina studied her samples and find sample proportions of a specific characteristic (proportion of people who chose new item) from two different samples of people who are identifying themselfves in a period of change and people who are not)
For example, if she further continues the study and finds with 95% confidence that proportion of people who are in a perid of change choses new item are higher than the proportion of people who are not in a period of change, then she would have made inferential statistics.
Add 6x and x to have 7x.
-1+6x+x=-1
7x-1=-1
+1=+1
7x=0
Divide 7x by 7 so the x can be left alone.
X=0
Answer: 2,977,200 miles per hour
Step-by-step explanation: This is true because taking that that is miles per second there is 60 seconds in a minute so times that by 60 and there are 60 minutes in an hour so times that last answer by 60 again which gives you the answer
Step-by-step explanation:
from,
An = 4n -13
A1 = 4 (1) - 13
> A1 = -9
A2 = 4(2) - 13
> A2 = -5
A3 = 4(3) - 13
> A3 = -1
A4 = 4(4) - 13
> A4 = 3
