Answer:
116,280 different leadership structures are possible
Step-by-step explanation:
The order is important.
For example, a Committee of John, Elisa, Laura and Rose means that John is the chairperson, Elisa the vice-chairperson, Laura the secretary and Rose the treasurer. If we exchange John and Elisa, their roles are also exchanged. This means that we use the permutations formula to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:

How many different leadership structures are possible
Permutations of 4 elements from a set of 20. So

116,280 different leadership structures are possible
Answer:
The time spend to burn energy is 3300 minutes .
Step-by-step explanation:
Given as :
The speed at which the bike ride = 10 miles per hours
The energy burn while riding = 550 calories
Let The time spend to burn energy = t minutes
So, According to question
Time spend = 
i.e t =
hours
∴ t = 55 hours
So, in minutes
The time spend
1 hours = 60 min
∴ 55 hours = 60 × 55 = 3300 minutes
So, The spend to burn energy = t = 3300 minutes
Hence The time spend to burn energy is 3300 minutes . Answer
Answer:
1/38
Step-by-step explanation:
Given :
Probability = required outcome / Total possible outcomes
Total possible outcomes = total Numbe rod sections = 38
Required outcome = number of 1's on the entire section = 1
Hence, the probability of spinning a one equals :
P(spinning a 1) = 1 / 38
Answer:
3 / 10
Step-by-step explanation:
