Option (a):
The population as well as the aim of study is not defined. Hence, it is incorrect.
Option (b):
As the girls belong to soccer team, the views towards their favourite sport would likely be biased and they will probably chose soccer as their favourite sport. This is incorrect.
Option (c):
The nature of data is not described. Also we don't know whether the sample drawn was random or biased. Hence, this option is also incorrect.
Option (d):
In this scenario, the sample is drawn randomly. The aim of the study is also clearly defined. Hence, this option is correct.
Answer:
Use the distance formula. Result: sqrt [ (a-c)^2 + (b-d)^2 ]
Step-by-step explanation:
distance = d = sqrt [ (a-c)^2 + (b-d)^2 ]
Answer:
x = 9
Step-by-step explanation:
Well, let's solve it!
x - 9 = 0
Let's add 9 to both sides to isolate the variable and maintain equality.
We end up with :
x = 9 since -9 and 9 cancel out and 0 + 9 = 9.
Answer:
Yes you would know
Step-by-step explanation:
We can view these tents as sides on a shape that is 30 sided, with lines connecting each tents together.
After this we calculate the interior angle of each side, and use our given 20m to calculate it.
