Hope that helped :D
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
D igneous intrusions is because it is the valuable
I agree. because you never know. you might go to the career and you dont like so you have to research about it to get a great job
Answer:
z = 1.00
Explanation:
Given:
Probability of z value = 0.6826
By using standard normal table for z value.
P(-z < Z < z) = 0.6826
P(Z < z) - P(Z < -z) = 0.6826
We know that
P(Z < z) + P(Z < -z) = 1
So,
2P(Z < z) - 1 = 0.6826
2P(Z < z) = 1 + 0.6826
2P(Z < z) = 1.6826
P(Z < z) = 1.6826 / 2
P(Z < z) = 0.8413
So,
P(Z < 1.00) = 0.8413
z = 1.00
