30 books represent 2% of the total books at library 1. how many books are in library 1?

Answers

Answer:

There are 1,500 books in Library 1

Step-by-step explanation:

30 = 0.02x

Divide 0.02(or 2%) from both sides

1,500

You need to divide the 20 books by the percentage that they are compared to the total amount.

(\) QueTooOfficial (/)

Final answer:

To find the total number of books in Library 1, we can use the concept of percent. We are given that 30 books represent 2% of the total books in Library 1. By setting up and solving an equation, we find that the total number of books in library 1 is 1500.

Explanation:

To find the total number of books in Library 1, we can use the concept of percent.

Let's represent the total number of books in library 1 as x.

We are given that 30 books represent 2% of the total books in Library 1.

So, we can set up the equation:

2% of x = 30

To solve for x, we need to isolate it on one side of the equation. To do this, we can divide bothsides of the equation by 2% or 0.02.

x = 30 ÷ 0.02 = 1500

Therefore, the total number of books in Library 1 is 1500.

60 paintings. T= Painting from 20th century. B= British painting. A painting is chosen random.it is from the 20 century. Work out the probability it is British

Answers

The probability will be "0.20".

According to the question,

The sum of all the areas = 60

then,

$x(x-2)+x+(2x+8)+10=60$
$x=6$

Therefore,

→ $P (British | It's \ from \ the \ 20^(th) \ century) = (n(B \ and \ T))/(n(T))$

$= (x)/(x+x(x-2))$

$= (6)/(6+6(6-2))$

$= (1)/(5)$

$= 0.20$

Thus the answer above is right.

Final answer:

This question is about computing the conditional probability that a painting selected at random is British, given it's from the 20th century. Without specific numbers, the tentative solution is the ratio of the number of British 20th-century paintings to the total number of 20th-century paintings.

Explanation:

The subject here is Probability, a topic within Mathematics. Let us assume without losses in generality that 'T' represents a painting from the 20th century and 'B' represents a British painting. Given 60 paintings, we're selecting one at random. The condition is it's a 20th-century painting ('T') and we need to find the probability that it's also a British painting ('B'). The data given in the question isn't clear enough to give a numerical answer. However, we can give a general solution.

Firstly, we find the number of paintings which are both from 20th century and British. Let's say this number is n. The number of 20th-century paintings would be more than or equal to n. Let's call this N. Therefore, the required probability would be n/N.
