Five students are competing in a race. In how many different
Dimas [21]

Answer:

120

Step-by-step explanation:

• we need to find the number of the possible orderings

of this five students.

•• which we can simulate to a permutation

of 5 objects.

••• and we know that The number of permutations

of 5 distinct objects is 5!.

5! = 5×4×3×2×1 = 120

there are six permutations of the set {1, 2, 3}, namely (1, 2, 3), (1, 3, 2), (2, 1, 3), (2, 3, 1), (3, 1, 2), and (3, 2, 1). These are all the possible orderings of this three-element set.

The number of permutations of n distinct objects is n factorial, usually written as n!, which means the product of all positive integers less than or equal to n.

the larger of two numbers is 12 more than the smaller number.if the sum of the two numbers is 74,find the two numbers
jek_recluse [69]
X = larger number, y = smaller number

x = y + 12
x + y = 74

y + 12 + y = 74
2y + 12 = 74
2y = 74 - 12
2y = 62
y = 62/2
y = 31

x = y + 12
x = 31 + 12
x = 43

so ur 2 numbers are : 43 and 31
