Ask every fifth person that exits the school
(systematic random)
Answer:
0.52
Step-by-step explanation:
(13/25)(4/4)=52/100
52/100=0.52
Use Pythagorean theorem:
9i-j = sqrt (9^2 - 1^2) = sqrt(81-1) = sqrt80
now divide both terms in V by that:
u = 9/sqrt(80)i - 1/sqrt(80)j
see attached picture:
1/5(25-5a)=4-a
⇔5-a=4-a
