Answer:
Yes, it is representative because each type of book was represented in the approximate proportion that exists in the library.
Step-by-step explanation:
Given is a chart, showing the distribution of the number of books in a library.
Also given that Sahira chooses a random sample from the library and records the type of books in the chart below.
Sahira's sample can be said to be representative because given that books are taken at random. So just because literacy books were more we cannot say it is not representative II option is not right, because each book was not chosen uniquely, just random books were drawn
Lastly The Answer is C) Yes, it is representative because each type of book was represented in the approximate proportion that exists in the library is right, because each book selected represents the sample from population of full library books.
Answer:
1.35764501988
Step-by-step explanation:
x = -16 or x = 5
Solution:
Given polynomial:
To find the roots of the polynomial.
Split the middle term 11x.
11x = 16x - 5x
Take the x common in first 2 terms an -5 common in next 2 terms.
Take (x + 16) common in both terms.
x + 16 = 0 or x - 5 = 0
x = -16 or x = 5
Hence x = -16 or x = 5.
