<h3>
720 different ways</h3>
Step-by-step explanation:
Permutation has to do with arrangement. If r objevt selected from n pool of objects are to be arranged in a straight line, this can be done in nPr number of ways.
nPr = n!/(n-r)!
If 5 people are to be chosen and arranged in a straight line, if there are 6 people to choose from, this can be done in 6P5 numbe of ways.
6P5 = 6!/(6-5)!
6P5 = 6!/1!
6P5 = 6*5*4*3*2*1
6P5 = 720 different ways

Answer:
12.
Step-by-step explanation:
Replace k in the radical by -2:
So we have √(-72*-2)
= √144
= 12.
You add the legnths of the sides together exg
if you have rectangle with width=2 legnth=3
permiter=w+w+l+l=2+2+3+3=10
Answer: 2.5%
3967.50 - 3450 = 517. 50
i = prt/100
i = 517.50, p = 3450, t = 6
517.50 = 3450 x r x 6/ 100
517.50 = 20700r/100
517.50 = 20700r
517.50/20700 = r
r = 0.025 = 2.5%
