<u>Answer:</u>

Permutation - requires to arrange order with quantities

Combination - order is not required

<u>Step-by-step explanation:</u>

If a question demands you to select as well as arrange the given quantities then it means that it is a problem of permutation.

While on the other hand, a problem of combination would only ask you to select the quantities and not their order.

So with practice, you get to know how exactly it works.

Answer:

Step-by-step explanation:

Permutation is the ways in which a fixed group or members that can be arranged or ordered and combinations are used when a smaller group has to be chosen from a larger group.

Examples:

<u>Permutation: </u>How many unique combinations of the word MAHNOOR can be formed when the letters will be scrambled

2. In what order or arrangements five people can be seated in the front row?

The number of people are fixed, we have to find the order.

<u>Combination:</u> Choosing two cards from a deck of 52 cards. We are choosing a small group from a larger group of all cards.

2. Choosing 4 students from a class to take part in the competition.

The total amount of weight on an elevator cannot exceed 1,800 pounds. a delivery person is on the elevator delivering packages.
HACTEHA [7]

Answer:

p ≤ 8

Step-by-step explanation:

Given the following :

Maximum weight elevator can hold ≤ 1800

Weight of delivery person and packages = 520 pounds

Average weight of a person = 160 pounds

Inequality to show how many additional people elevator can hold?

(weight of delivery person and packages + average weight of persons * number of persons) ≤ 1800

Let p = number of persons

(520 + 160p) ≤ 1800

160p ≤ 1800 - 520

160p ≤ 1280

p ≤ 1280 / 160

p ≤ 8

nikdorinn [45]

The two expressions that are comparable to one another for the total cost of the cloth are and

(7.99 × 7/3) and 18.64

This is further explained below.

<h3>What is expressions ?</h3>

In most cases, the two expressions that are comparable to one another for the total cost of the cloth are

(7.99 × 7/3) and 18.64

Total cost = Cost of fabric per yard * Number of fabrics

= 7.99 × 2 1/3

= (7.99 × 7/3)

= 55.93 / 3

= 18.64

As a result, the two expressions that are comparable to one another for the total cost of the cloth are and

(7.99 × 7/3) and 18.64
