Answer: The percentage of parents who use cloth diapers in the sample is the statistic.
Step-by-step explanation:
- A statistic is the measure of a particular characteristic in the sample which is nothing but a subset of population.
Here, the concern is to estimate the percentage of parents who use cloth diapers.
He took a sample of 125 parents to enquiry whether or not they use cloth diapers.
So, the percentage of parents who use cloth diapers 9in the sampl is the statistic.
Let x be the price of the blouse.
42=2x-14
56=2x
28=x
The blouse was $28

Answer:
2n - 11
Step-by-step explanation:
Note there is a common difference d between consecutive terms of the sequence, that is
d = - 7 - (- 9) = - 5 - (- 7) = - 7 + 9 = - 5 + 7 = 2
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 9 and d = 2, thus
= - 9 + 2(n - 1) = - 9 + 2n - 2 = 2n - 11
I hope this isn't too late! You can find the answer to this by first finding the area of the circle, A=πr². So since the radius is 10, we input that into the equation to get π100. Now, there is 360° in a circle and a sector of 90° is 1/4 of it. So to answer the question all you have to do is find 1/4 of the area of the circle.
The answer is π25.
To solve the other questions on your assignment just think about how much the sector is of the full 360° of the circle, for example 180° is 1/2 of the circle or 270° is 3/4 of the circle, and multiply the fraction by the area of the circle.
Hope this helped, good luck! :)
