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.
Well slope means <span>a surface of which one end or side is at a higher level than another; a rising or falling surface.</span> So pretty much its just saying he had 6 litters used 4 of those litters and had a remainder of 2. So you can say the slope means that he was decreasing in litters by using 2 litters every 1 hour. I don know really if it´s correct so, sooopppeeerrrr sorry. :( :) bye

Answer:
D
Step-by-step explanation: because W in the equation is the number of weeks she paid for the self defense class. and the 12.50 would be the registration fee because that is added on top of the number of 40w.
40w + 12.50 = 492.50
-12.50 -12.50
40w = 480.00
w = 12 which is how many weeks she paid
The value of y is 83 degrees because any quadrilaterals opposite sides or angles are equal and opposite (or diagonal) from point D.
Hope this helps !
