Answer:
A
Explanation:
You must know the basics of Trigonometry to solve this.
First, you must know that
lies in the second quadrant, so sin is negative.
Next, since
pi/4, is the reference angle of 3 pi/4, this means that we can set up a right triangle with pi/4 as an angle, we get
So the answer is A
I just use regular ones cause I don’t like to reuse :)
Answer:
Where are the events? Do we hav e to make them up?
In Statistics, when you are is using the standard normal distribution, P(z < 0) = 0.5.
<h3>What is a normal distribution?</h3>
A normal distribution is also referred to as the Gaussian distribution and it can be defined as a probability distribution that is continuous and symmetrical on both sides of the mean, which shows that all data near the mean have a higher frequency than data that are far from the mean.
This ultimately implies that, when you are is using the standard normal distribution, P(z < 0) must be equal to 0.5 because it has a median of zero (0).
