Answer:
P43=4!(4–3)!=241=24
Step-by-step explanation:
There are four choices you can make for the lead reindeer. For each possible choice, there are then three remaining you can choose to fly second, making 4×3=12 choices for the lead pair. For each possible choice there are two remaining reindeer to take up the back position, making 12×2=24 choices for the team of three.
This type of problem is called a permutation problem, and we write Pnr for the number of ways of choosing r items from n possibilities when the order of the items matters. In this case we are choosing 3 reindeer from 4 possibilities, and the order they appear in the flying line does matter, so the answer we want is P43. The general formula is Pnr=n!(n−r)!. For the answer we are looking for we therefore have:
P43=4!(4–3)!=241=24
An ordered pair is written as (x, y)
P(-3) = 18
The -3 is the x value and the 18 is the y value
Answer: (-3,18)
The answer is obtuse triangle
Answer:
7/15
I hope this helps and I apologize if I'm wrong.
Can you tell me if I was wrong or right?
Answer:
Equilateral and acute
Step-by-step explanation:
Notice that the angles of the triangle are all 60 degrees which is less than 90 degrees. Also notice the lines in the middle of the triangle lines, those signify that the lines are the same length. Thus making it acute and equilateral
