Step 1: Find out how many cm3 is filled in a minute.
750000/30 = 25000cm3 per minute
Step 2: Find out how many minutes it takes to fill 1200000cm3.
1200000/25000 = 48 minutes
Answer: 48 minutes
Answer: C) 150°
Step-by-step explanation: all the angles are the same
Answer:
j = 38
Step-by-step explanation:
j/-2 + 7 = -12
first subtract 7 from both sides
j/-2 = -19
then multiply both sides by -2
j = 38
Answer:
d = 244

Answer:
Step-by-step explanation:
Given that a parking lot has two entrances. Cars arrive at entrance I according to a Poisson distribution at an average of 3 per hour and at entrance II according to a Poisson distribution at an average of 2 per hour.
Assuming the number of cars arriving at the two parking lots are independent we have total number of cars arriving X is Poisson with parameter 3+2 = 5
X is Poisson with mean = 5
the probability that a total of 3 cars will arrive at the parking lot in a given hour
= P(X=3) = 0.1404
b) the probability that less than 3 cars will arrive at the parking lot in a given hour
= P(X<3)
= P(0)+P(1)+P(2)
= 0.1247
