The number of possible ways to organize these books based on their number is 240.

<h3>What is the combination?</h3>

In math, this is the concept that describes the organization of a set of elements such as books, people, etc. This concept differs from permutation because in combination, the order does not matter.

<h3>What is the combination formula?</h3>

The genral formula is:

  • nCr = n! / ((n – r)! r!) n
  • n= total of elements
  • r= elements to be used

But in this case, whe can use the n!.

Based on this, let's find out the total ways the books can  be arranged:

  • Math books: 5! = 5 x 4 x 3 x 2 x 1= 120
  • Social studies books = 1! = 1
  • Science books= 2! = 2 x 1 = 2
  • 120 x 1 x 2 = 240 ways

Note: This question is incomplete; here is the complete question:

Tthere are 5 different math books, 1 social studies book, and 2 different science books on the shelf. how many different ways can the books be arranged  if the books of each type must be together?

DedPeter [7]
Eddie is correct about his prediction. A coin has two sides, one head, one tail, so there is a 50% chance that it will land heads every time Eddie flips the coin. I would tell Eddie that his prediction is reasonable and mathematically correct.

Varvara68 [4.7K]

Answer:

The answer to your question is: Ф = 43.95°

Step-by-step explanation:

Data

length = 18 ft

distance bottom to is 13 ft

x = angle = ?

Formula

cos Ф = opposite side / hypotenuse  

Process

cos Ф = 13 ft / 18 ft                   substitution

cos Ф = 0.72                            simplify

Ф = cos⁻¹ (0.72)

Ф = 43.95°                                result
