A graphing calculator shows the rocks are at the same height 1.5 seconds after they are released.
That height is 3.975 meters.
_____
f(x) = g(x)
-4.9x^2 +15 = -4.9x^2 +10x
15 = 10x . . . . . . . . . . . . . . . . . . add 4.9x^2
1.5 = x . . . . . . . . . . . . . . . . . . . divide by 10
f(1.5) = -4.9*2.25 +15 = 3.975
Answer:
0.91824 = 91.824% probability that more than 3 students will have their automobiles stolen during the current semester.
Step-by-step explanation:
We have only the mean, which means that the Poisson distribution is used to solve this question.
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 interval.
Suppose that on the average, 7 students enrolled in a small liberal arts college have their automobiles stolen during the semester.
This means that
What is the probability that more than 3 students will have their automobiles stolen during the current semester?
This is:
In which
So
Then
0.91824 = 91.824% probability that more than 3 students will have their automobiles stolen during the current semester.
20.8.
You multiply 5.2 times 4
