Simplify the trigonometric expression.
Call the expression E:
So basically E is equivalent to
where the sign depends on which quadrant
lies. Shortly,
I hope this helps. =)

Answer:
C. 7
Step-by-step explanation:
Therefore, by Basic Proportionality theorem:
Answer:
A) cluster sampling ( b ) and systematic sampling ( e )
B ) Randomly selecting precincts increases the likelihood that the people polled represent the population well. ( c )
Step-by-step explanation:
Cluster sampling is a type of sampling plan used when there is an internally heterogeneous groups can be found inside a population that is supposed to be mutually homogeneous . while systematic sampling is a type of probability sampling that involves the selection of samples from a larger population at random but using a specific interval. to get the systematic sample the larger population is divided by the sample size.
from the information available in the report it is very evident that not all voters can be captured at once hence cluster sampling and systematic sampling would be employed .
B) the company will randomly select precinct to increase the likelihood of the sample size representing the entire population very well
The formula for the circumference of a circle if you have diameter is:
pi multiplied by diameter
So, 3.14 multiplied by 8 is equal to 25.12
The circumference of the circle is 25.12 cm
Hope it helps :)
