Jasmine has 5 books that she wants to read. she wants to read the nonfiction book first and the mystery book last. in how many different orders can she read the books?

We have been given that Jasmine has 5 books and she wants to read the nonfiction book first and the mystery book last. It means that the time of reading of 2 books are fixed. Now she has 3 books which she needs to arrange.

Now, we know that n different things can be arranged in n! ways. We can use this concept to find the number of different orders can she read the books.

Using the above concept, 3 books can be arranged in 3! ways.

Therefore, there are 6 different orders in which she can read the books.

entering that problem on the tube might get you an answer

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
