Take the root of both sides, and solve.
x = 2i sqrt 2, -2i sqrt 2.
Answer:
Option D
Step-by-step explanation:
A). From the graph attached,
Arrow AB represents the RISE and arrow BC represents the RUN.
B). RUN from point A to B (Horizontal distance) = 2 units
Rise from point A to B (Vertical distance) = -4 [Since, downwards arrow represents negative notation]
Slope of the line segment AB =
=
= -2
Therefore, slope of the line = slope of the line segment AB = -2
Option D will be the correct option.
Answer:
y = -cos(2x)
Step-by-step explanation:
Mean/mid line: y = 0
It's a negative cos, with period pi.
So, y = -cos(2x)
Just count up from 9:30. 5 and 1/2 hours is the answer
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.
