As per the combination method, there are 15 different ways are possible for this situation.
Combination method:
Combination method also known as NCR is a formula of combination and arrangement, where the object's order does not matter so much.
Given,
Here we have to find the number of ways to be selected as the best student and another student is to be selected as a runner-up among the 6 students.
Here we know that that the value of
Total number of students = 6
Best student = 1
Runner - up = 1
So, as per the NCR formula, the value of n = 6 and the value of r = 2
Then the possible combinations are calculated as,
=> ⁶C₂ = 6! / 2!(6 - 2)!
=> ⁶C₂ = 6!/2!4!
=>⁶C₂ = 15
Therefore, the resulting number of ways is 15.

Answer:
6.5
Step-by-step explanation:
39/6 comes out to 6.5
Denali- 6.7x70= 469
The building should be strong enough to withstand an earthquake of that magnitude.
Rat Island- 7.8x30=234
The building should be string enough to withstand an earthquake of that magnitude.
Hope this helps! ;)
