Answer:
c) 72% is a statistic and 56% is a parameter.
Step-by-step explanation:
Previous concepts
A statistic or sample statistic "is any quantity computed from values in a sample", for example the sample mean, sample proportion and standard deviation
A parameter is "any numerical quantity that characterizes a given population or some aspect of it".
Solution to the problem
For this case we know that they select a sample of 663 registered voters and the sample proportion from these registered voters is:
representing the sample proportion of people who voted in the election
They info that they have is that the true proportion before is 
and that represent a value related to the population.
So on this case the 0.72 represent a statistic since represent the sample and the 0.52 is a value who represent the population for this case is a parameter.
So the correct option is:
c) 72% is a statistic and 56% is a parameter.
Follow the a² + b² = c² formula
The hypotenuse always equal the c
a and b can be the other two numbers and are interchangeable
plug in 5 and 6 into a and b
(5)² + (6)² = c²
simplify
25 + 36 = c²
add
c² = 61
isolate the c, root both sides
c² = 61
√c²= √61
c = √61
Roots are Irrational numbers, and so D) irrational number should be your answer

Answer:
Supplementary, 39+5x=180, x=28.2
Step-by-step explanation:
So we know that a straight line is 180 degrees, therefore 52+(5x-13) must equal 180. This is a supplementary relationship. That's our equation, now we just have to solve.
52+5x-13=180
We can straight away combine numbers, giving us
39+5x=180
Now we subtract 39 from both sides, giving us
5x=141.
Now we will answer.
141/5=28.2=x
I'm not sure if this is right, but this is my answer :)
Answer:
the answer is 9.66 probably
Step-by-step explanation:
Step-by-step explanation: If two events are independent events, then the outcome of one event will not affect the outcome of the other event. I'll show an example.
Two coins are tossed. Find the probability of the following event.
P (heads and heads)
This problem would be dealing with independent events because the outcome of tossing 1 coin does not affect the outcome of tossing the second coin.
