Step-by-step explanation:
medals?
Decide if the situation involves a permutation or a combination, and then find
the number of ways to award the medals.
Answer: Permutation; number of ways = 120
Step-by-step explanation:
Answer with explanation:
Number of runner= 5
Number of Distinct Medal = 5
First Medal can be Awarded in 5 ways, second Medal can be awarded in 4 ways and third Medal can be awarded in 3 ways , fourth medal can be awarded in 2 ways and fifth Medal can be awarded in one way.
So, total number of ways =5 × 4×3×2×1=120 way
⇒We will use the concept of Permutation as there are five distinct medal and five different runners
So, Five distinct places can be filled in 5! or ways as order of arrangement is Important because any of the five candidates can win first second, third , fourth or fifth Prize.
= 5!=5×4×3×2×1=120 ways
Because, n!=n×(n-1)×(n-2)×........1.
Answer:
slope intercept form: y=5x+9
standard form: x-5/y =-9/5
Step-by-step explanation:
slope intercept form: y=mx+b, m=slope, b=y-intercept
m= 5, b=9 therefore,
y=5x+9
