Answer:
90 different ways
Step-by-step explanation:
We have a total of 10 members, and we want to find how many groups of 2 members we can have, where the order of each member in the group of 2 is important, so we have a permutation problem.
To solve this problem, we need to calculate a permutation of 10 choose 2.
The formula for a permutation of n choose p is:
So we have:
So there are 90 different ways of choosing a president and a vice-president.
Answer: 28
Step-by-step explanation:
Given
Kenny made 7 serves over the net for every 2 serves that did not go over the net i.e. success rate of Kenny is
for 36 serves, applying the same success rate, it is
Serves that did not make over the net is
Thus, Kenny will make 28 serves that make over the net
Answer:
The temperature in Kelvin corresponding to F degrees Fahrenheit is
Step-by-step explanation:
Given : One can convert temperature from Kelvin into Fahrenheit using the formula .
To find : What is the temperature in Kelvin corresponding to F degrees Fahrenheit?
Solution :
Temperature from Kelvin into Fahrenheit is given by,
Writing Kelvin in terms of Fahrenheit,
Subtract 32 both side,
Divide by 95 both side,
Add 273 both side,
Therefore, The temperature in Kelvin corresponding to F degrees Fahrenheit is
