The constant of proportionality between the number of fiction book (f) and the number of nonfiction books (n) in a library is 15/22. There are 3498 nonfiction books in the library. How many fiction books are in the library

Answers

2385  I think

Step-by-step explanation:

The total number of fiction books in the library are 2385.

What is the constant of proportionality?

The constant of proportionality is the ratio of two proportional values at a constant value.

Let the total number of fiction books be f and nonfiction books be n.

According to the given question.

The constant of propotionality between the number of fiction book(f) and the number of non-fiction books(n) in a library is [tex]\frac{15}{22}[/tex].

[tex]\implies \frac{f}{n} = \frac{15}{22}[/tex]

Also, the total number of nonfiction books is 3498.

Therefore,

[tex]\frac{f}{3498} = \frac{15}{22}[/tex]

[tex]\implies f = \frac{15}{22} \times 3498[/tex]

[tex]\implies f = 15\times 159[/tex]

[tex]\implies f = 2385[/tex]

Hence, the total number of fiction books in the library are 2385.

Tina is packing for a five-day trip. She has one blue, one red, one white, one green, and one grey t-shirt. Tina will not wear each t-shirt more than once. What is the probability that Tina will wear blue on the first day of her trip and then wear grey on the second day of her trip?

2/5


1/5


1/20


1/25

Answers

the answer is 1/5 because there’s 5 shirts but a 20% change which is also 1/5 she’ll pick the blue one.

The probability of Tina wearing blue on the first day of her trip and then wearing grey on the second day of her trip is 1/20.

What is Probability?

It is a branch of mathematics that deals with the occurrence of a random event.

The probability of Tina wearing blue on the first day of her trip is 1/5, since she has 5 t-shirts to choose from and only one of them is blue.

After wearing the blue t-shirt on the first day, Tina will have 4 t-shirts left to choose from for the second day. Only one of those t-shirts is grey, so the probability of Tina wearing grey on the second day given that she wore blue on the first day is 1/4.

The probability of both events happening (Tina wearing blue on the first day and then grey on the second day) is the product of the individual probabilities:

P(blue on first day and grey on second day) = P(blue on first day) x P(grey on second day | blue on first day)

P(blue on first day and grey on second day) = (1/5) x (1/4)

P(blue on first day and grey on second day) = 1/20

Therefore, the probability of Tina wearing blue on the first day of her trip and then wearing grey on the second day of her trip is 1/20. So, the correct option is 1/20.

They settle on picking the letters L, E, A, and P from a bowl, replacing them after each pick, to make the decision. They repeat this experiment 40 times to verify their model and record the results in this table.
Below is the chart

Based on the results in the table, is this model a fair representation for choosing an activity?
A.
No, it is an unfair model because the outcomes have different frequencies.
B.
No, it is an unfair model because the relative frequency of the letter E is the highest.
C.
Yes, it is a fair model because the relative frequencies of the letters L and P are equal.
