Answer:
Answer is 0.5
Step-by-step explanation:
The text implies that the number of traffic accidents determines the number of ambulances required on the road. Hence, 1 traffic accident requires 1 ambulance.
The time slot and time of day remain same in both the text and the question.
The average or mean number of accidents is 1.1
QUESTION: What then is the probability that there is need for exactly 2 ambulances on that road and in that time frame?
In other words, what is the probability that there'll be 2 accidents on that road and in that time frame?
Since the mean number of accidents is 1.1, 2 is above the mean.
Probability of 1.1 accidents is 1, since that's the mean (expected value).
Probability of 2 accidents is 1/2 which is = 0.5
W is equal to 6 because 6/3=2 so 2+6=8
Answer:
Step-by-step explanation:
pull like terms from the problem to re-arrange it into a product
He works 5 hours per week. let x represent the number of weeks.
the equation is 5x=y
in the x boxes put: 1 2 3 and 4
in the y boxes multiply each number by 5.
x-y
1-5
2-10
3-15
4-20
