It is important to keep a
close eye on all the information’s that are given in the question. Based on
those given information’s the answer can be easily deduced.
The distance traveled by Linda in 3 hours = 4.8 miles
Then
In 1 hour the distance traveled by Linda = (4.8/3) * 1 miles
= 1.6 miles
So the speed of Linda is 1.6 miles per hour.
I hope the procedure is simple
enough for you to understand. You can always solve similar kind of problems
using this simple procedure.
Answer:
This question involves a Permutation as the order is important; the lead is chosen first, and then the backup singer is chosen.
Step-by-step explanation:
Consider the provided information.
Whenever the position or order matters, use permutation.
If position or order does not matter, then it's a case of combination.
Now director choose a lead singer and then a backup singer in this case position matters.
Suppose David is lead singer and John is backup singer this scenario is different form John is lead singer and David is backup singer.
Thus, order matter so we will use permutation.

The number of players compete in round 7 will be 4.
Step-by-step explanation:
The number of players in a tennis tournament is reduced by half (50%) after every round. In round 1 there are 256 players, in round 2 there are 128 players, and so on.
So, the number of players is multiplied by 
gives the number of players in the next round.
Therefore, the explicit function of number of players in nth round is given by
where .
Therefore, the number of players compete in round 7 will be 
. (Answer)
