Answer:
12.76% probability that there is exactly 1 reported crime on any given day.
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.
Statistics from the Riverside Police Department show that in the last 12 years there were 648 reported crimes in the city.
Each year has 365 days. We want the mean for a day. So
Find the probability that there is exactly 1 reported crime on any given day.
This is P(X = 1).
12.76% probability that there is exactly 1 reported crime on any given day.
Answer:
well, the second score would be -3
Step-by-step explanation:
first game: +3
second game: - 3
Total: 0
3 - 3 = 0
Hope it Helps!
Take you the common factors. those are 2 and x. So if you divided 2x^2 by 2x you end with only one x. and if you divided 4x by 2x you end with 2. The final answer should look like 2x(x+2)=2x^2+4x
Wilda can do the job in 4 hours ... she does 1/4 (or 0.25) of it each hour.
Karla can do it in 5 hours ... she does 1/5 (or 0.2) of it each hour.
Wilda worked alone for 1 hour ... 0.25 of the job was done before her helper
arrived. So only 0.75 of the job remained to be done together.
Working together, they accomplish (0.25 + 0.2) = 0.45 of the job in 1 hour.
How many times do they need to do 0.45 of the job in order to finish
the 0.75 of it that remains ? That's the number of hours it will take them,
working together.
0.75 / 0.45 = <em>1 and 2/3</em>
After Wilda worked alone for 1 hour and Karla came along to join her, it will
take them another <em>1 hour and 40 minutes</em> to finish the job and go for a swim.
we can establish a ratio since triangle MNQ is equal to Triangle MLP.
your answer is B 9 inches
