Refer to the diagram shown.
Let x = the distance from the base of three to where the rope is tied.
By definition,
tan 30° = 8/x
0.5774 = 8/x
Multiply each side by x.
0.5774x = 8
Divide each side by 0.5774
x = 13.855 ft
Answer: 13.9 ft (nearest tenth)
Answer:
400
Step-by-step explanation:
The two is less than 5 so it becomes 0 and so does the 7
Answer:
a number produced from a subset of the group of interest.
Step-by-step explanation:
This problems is, basically, about the difference of concepts between a statistic and a parameter.
When something is taken from a sample and estimated to the entire population, it is a statistic. For example, if you survey 200 Central New York residents, an 60% of them say they are Buffalo Bills fans, the 60% is a statistic.
When something is true to the entire population, it is a parameter. If i study the voting preference of all 53 players on the Buffalo Bills active roster, and 83% are Democrats, the 83% is an parameter.
So the correct answer is:
a number produced from a subset of the group of interest.
This subset is the sample, for example, and the group of interest is the population.
The first one
