Answer:
20x^2-10x+8
Step-by-step explanation:
8+x2-4x3 +5x 2x2
20x^2-10x+8
i hope this helps!
You first set up a proportion
16/100 = x/90
then cross multiply 16*90
and 100*x
1440 = 100x
divide each side by 100
1440/100 = 100x/100
100 cancels out on the right side
the answer is
14.4=x
Answer:
The probability that the person gets a speeding ticket is 0.27
Step-by-step explanation:
The probability that the person receives a speeding ticket is the probability that the person passes through any of the speed limits and the radar is operating at that time.
Let
is the probability that the person passes through radar
and it is operating at that time is

Where
P(1) is the probability of person passes through 
P(2) is probability that the radar is operating

Similarly the probabilities are calculated for other radars in the similar manner as


Thus the reuired probability of the reuired event is
