Answer:
Part A is 1/4
Part B is 3/4
Step-by-step explanation:
1(A):3(B)
brainliest?
Step by step
One sixth of the sum 1/6 ( + )
the sum of d and 3 1/6 (d+3)
minus the product 1/6 (d+3) - ( )( )
The product of 4 and q 1/6 (d+3) - 4q
The product of p and 3 3p
is subtracted from - 3p
three-fourths of s 3/4 s - 3p
three-fourths the sum 3/4 ( + )
the sum of 9 and k 3/4 (9+k)
Obviously, the final line in each case is the answer.
The last option c is right because each book selected represents the sample from the population of full library books.
We have given that,
Sahira chooses a random sample from the library and records the type of books in the chart below.
Type of Book Number
Fantasy 10
Literature 25
Children’s 4
Nonfiction 11
t, 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 books literature 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.
<h3>
What is the population?</h3>
A population is defined as a group of individuals of the same species living and interbreeding within a given area. Members of a population often rely on the same resources, are subject to similar environmental constraints, and depend on the availability of other members to persist over time.
The last option c is right because each book selected represents the sample from the population of full library books.

Complete the square since can't factor
2/2=1
add 1 to both sides
x²+2x+1-6=1
factor perfect square
(x+1)²-6=1
add 6 to both sides
(x+1)²=7
sqrt both sides
x+1=+/-√7
minus 1 both sides
x=-1+/-√7
so x=-1+√7 or x=-1-√7
