(2/3)(30)=20
30+20=50=(x/5)
(50*5)=x=250

Answer: "13,000 books" represents the population.
"200" books represents the sample.
Step-by-step explanation:
- A population is the term that denotes a whole large possible group of individuals, objects, events or measurements.
- A subset of population is known as ample.
- When population is too large to the researcher , then it uses sample to represent the entire population.
Here, "13,000 books" represents the population.
"200" books represents the sample which is a subset of 13,000 books.
Answer:


Step-by-step explanation:

a) about the line y = 3
⇒
is the intersection point
So,

b) about the line x = 5
⇒ 
So,

Answer:
The answer is P(6) is 44.
Step-by-step explanation:
Given:
If P(x) = x^2 + X + 2 and Q(x) = 3x^3 - 2.
Now, to find P(6).



Therefore, the answer is P(6) is 44.
45=k√5
times both sides by √5
45√5=5k
divide both sides by 5
9√5=k
