Answer:
Step-by-step explanation:
a. #We notice this is a Poisson probability function expressed as:
x-number of occurrences in a given interval.
-mean occurrences of the event
-The mean is calculated as:
#the probability of no accidents in a 15-minute period is :
Hence, the probability of no accident in a 15-min period is
b. The the probability of at least one accident in a 15-minute period. is calculated as:
Hence, the probability of at least one accident in a 15-minute period is
c. The probability of four or more accidents in a 15-minute period is calculated as:
Hence,the probability of four or more accidents in a 15-minute period. is 0.9997
Simplify 7/8-2/3
78−2378-23
To write 7878 as a fraction with a common denominator, multiply by 3333.
7833−237833-23
To write 2323 as a fraction with a common denominator, multiply by 8888.
7833−23887833-2388
Write each expression with a common denominator of 2424, by multiplying each by an appropriate factor of 11.
7⋅324−2⋅8247⋅324-2⋅824
Combine the numerators over the common denominator.
7⋅3−(2⋅8)247⋅3-(2⋅8)24
Simplify the numerator.
524524
The result can be shown in both exact and decimal forms.
Exact Form:
524524
Decimal Form:
0.208¯3
Answer:
maybe u missplaced it somehow and it also would depend if you trust that person or not. some times that 'friend' can turn out to be fake but i don't mean it about ur friend. for now, u should just ask, there's no harm in that.
Answer:
The half-life in days is 6.3 days
Step-by-step explanation:
Here, we want to get the half-life
From what we have in the question, we can see that we have a first order decay relation
For a first order decay relation;
t1/2 = ln 2/k
That will be;
t1/2 = ln2/0.1095
t1/2 = 6.33
To the nearest tenth, this is 6.3 days
70,000 - 16,000 = 54,000 (money needed from commissions)
