Answer:
The answer is "2653".
Step-by-step explanation:
Minimum sample size for Cl level and Desired Margin of Error, is:
The minimum n has to be integer, we take the ceiling Of above number and get n = 2663
The exact z-value.
using critical value of 2,575, which gives 2652.25
Answer:
The sine of the angle = the length of the opposite side. the length of the hypotenuse.
The cosine of the angle = the length of the adjacent side. the length of the hypotenuse.
The tangent of the angle = the length of the opposite side. the length of the adjacent side.
Step-by-step explanation:
(csc x-1)(csc x+1)=csc²x-1²=csc²x-1=(1/sin x)² -1=1/sin x² - sin²x/sin²x=
=(1-sin²x)/sin² x = cos² x/ sin² x = (cos x/sin x)²= (cot x)²
Answer:
False
Step-by-step explanation:
This is because there is no such thing! A double negative becomes a positive! Plz give brainliest!
