From a list of ten books, how many groups of 4 books can be selected

1 answer:

6 0

First you have all ten books, but then every time after, you loose one because you can't put the same book in the group twice.

10 * 9 * 8 * 7 = 5040 groups

DVD Video Rentals (Refer to Example 3.) The func-

Neporo4naja [7]

Answer:

$(a)\ V = \{(N,30),(R,37),(S,17)\}$

$(b)$

$Domain = \{N,R,S\}$

$Range = \{37,30,17\}$

Step-by-step explanation:

Given

$V(R) = 37,\ V(N) = 30,\ V(S) = 17$

Solving (a): Set of ordered pair

A function y = f(x) is represented as (x,y)

So, the ordered pair of V is:

$V = \{(R,37),(N,30),(S,17)\}$

Order the alphabets in increasing order

$V = \{(N,30),(R,37),(S,17)\}$

Solving (b): The domain and the range

In a function $\{(x_1,y_1),...,(x_n,y_n)\}$

The domain and the range are represented as:

$Domain = \{x_1,x_2....x_n\}$

$Range = \{y_1,y_2....y_n\}$

So, we have:

$Domain = \{N,R,S\}$

$Range = \{37,30,17\}$

What is the 1 in the 110

dezoksy [38]

You can divide 110 by 1 to see how many 1's go in 110:
110/1 = 110

This means that there are 110 1's in 110.

Hope this helps! :)
