No of people not from their neighborhood=25-20=5
total contact s=25
therefore probability to call a person not from his neighborhood=5/25=1/5
therefore P=1/5
Answer:
For each US dollar she gets 1.1 AUS dollars
Step-by-step explanation:
350US for 385AUS
350:385 divide by 350
1 : 1.1
Simplify the following:5 i/(3 i + 2)^2
(3 i + 2)^2 = 4 + 6 i + 6 i - 9 = -5 + 12 i:(5 i)/12 i - 5
Multiply numerator and denominator of (5 i)/(12 i - 5) by 5 + 12 i:(5 i (12 i + 5))/((12 i - 5) (12 i + 5))
(12 i - 5) (12 i + 5) = -5×5 - 5×12 i + 12 i×5 + 12 i×12 i = -25 - 60 i + 60 i - 144 = -169:(5 i (12 i + 5))/-169
i (12 i + 5) = -12 + 5 i:(5 5 i - 12)/(-169)
Multiply numerator and denominator of (5 (5 i - 12))/(-169) by -1:Answer: (-5 (5 i - 12))/169
Answer:
(a) 
(b) 
(c) 
Step-by-step explanation:
We have given velocity as function of t 
Acceleration is equation rate if change of velocity with respect to time
So 
(a) Acceleration at t = 5 sec
(b) Acceleration at t = 10 sec
(c) Acceleration at t = 20 sec
