Answer:
x = 7 , -1
Step-by-step explanation:
<u>SOLUTION :-</u>
- Add 11 to both the sides.
- Divide both the sides by 4.
- Root square both the sides.
Here , x will have two values -
1) 
2) 
<u>VERIFICATION :-</u>
When x = 7 ,
When x = -1 ,
X is greater than or equal to 0
y is greater than or equal to 0
a) The population is all of the flights belonging to the particular airline. It's not all flights in general because the airline does not have control over a rival company's flight schedule.
------------------
b) The sample is the 5 airlines the company selected. Ideally the sample should represent the population as much as possible. The larger the sample, the more representative the sample is.
------------------
c) No, the sample is likely <u>not</u> representative because one day of flight does not represent the entire lifetime of all flights done so far for that company. This particular day could have been a very good day with good weather, which may explain why the 5 flights were all on time.
------------------
d) It would be better for the company to select the days at random and sample all of the flights for those particular days chosen. This is a cluster sample. Each cluster is a day. Also, I think more flights should be sampled. Five flights does not seem like enough.
Answer:
y-2=1/3(x+6)
Step-by-step explanation:
y-2=1/3(x-(-6))
y-2=1/3(x+6)
Answer:
Step-by-step explanation:
The circumcenter is equidistant from the three vertices of the triangle. From the figure shown, we will prove DA = DB = DC. 2) DA = DB, DC = DB(If a point is on the perp. bisector of a segment, it is equidistant from each endpoint of the segment.)
