Answer:

the answer is 1.

Step-by-step explanation:

4 is equal to n so it would look like 24-7 but you have to multiply 2 and 4 which is 8. Then, you do 8-7 which is 1. hope this helped.

Find the number of unique permutations of the letters in the word: ONGOING
Kazeer [188]

Answer:

<h2>The Number of unique permutation is  6,615</h2>

Step-by-step explanation:

  This particular permutation  deals with words that have repeated letters.

Given word = "ONGOING"

the formula for the permutation is

= \frac{n!}{mA! mB!.....mZ!}

where   n   is the amount of letters in the word, and  m A , m B , ... , m Z  are the occurrences of repeated letters in the word. Each   m  equals the amount of times the letter appears in the word.

So in the word  "ONGOING"

n= 7

mO= 2

mN= 2

mG=2

permutations = \frac{7!}{2!2!2!} \\\\permutations= \frac{7*6*5*4*3*2*1}{(2*1)*(2*1)*(2*1)}

permutations=  \frac{52920}{8} \\permutation = 6,615

I don’t know how to do that
Alisiya [41]

Answer:

16

Step-by-step explanation:

Divide 64 by 8 to get 8. this is 1/8 of the books.

3/8 were non fiction, or 24

1/4 (2/8) were picture books, or 16

5/8 were non fiction or picture books, so ’the rest‘ of the chapter books is 3/8.

3/8 were chapter books, or 24.

add the amount of picture books and chapter books since they are the fictional texts.

16+24=40

subtract the amount of non fictional books from the amount of fictional books to get the sum.

40-24=16
