Answer:
1.83% probability there are no car accidents on that stretch on Monday
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given time interval.
The number of accidents on a certain section of I-40 averages 4 accidents per weekday independent across weekdays.
This means that 
What is the probability there are no car accidents on that stretch on Monday?
This is P(X = 0).


1.83% probability there are no car accidents on that stretch on Monday
Correct answer would be D. hope this helps :)
Answer:
370
Step-by-step explanation:
50 + x = 420
x = 420 - 50
x = 370
It is 10 to 1 significant figures
Let's assume the some number be h.
Now the given statement is "seven less than some number".
Which means we need to take out 7 from h. Hence, it can be translate into an algebraic expression as h-7.
