<span>−<span>45</span></span>
<span><span>
</span></span>
Explanation:
Since <span><span>tan<span>(θ)</span></span>=<span>34</span>>0</span> and <span><span>sin<span>(θ)</span></span><0</span>, θ is in quadrant 3 (since <span><span>tan<span>(θ)</span></span>>0</span> iff θ is in quadrant 1 or 3 and <span><span>sin<span>(θ)</span></span><0</span> iff θ is in quadrant 3 or 4).
<span>cos<span>(θ)</span></span> must then be negative.
Hey!

We know that (a = -3), (b = 2), (c = 5), and (d = -4).
----------------------------------------------------------------------
Solution #1:
≈ 1.57
----------------------------------------------------------------------
Solution #2:
= a - 4b / 3c + 2d
= (-3) - 4(2) / 3(5) + 2(-4)
= (-3) - 8 / 15 + (-8)
= (-3) - 0.53 + (-8)
= (-3.53) + (-8)
= -11.53
----------------------------------------------------------------------
Solution #1 Answer: 1.57
Solution #2 Answer: -11.53

Answer:
The population of interest for this student is the students whom are enrolled in statistics classes.
Step-by-step explanation:
Sampling
This is a common statistics practice, when we want to study something from a population, we find a sample of this population.
For example:
I want to estimate the proportion of New York state residents who are Buffalo Bills fans. So i ask, lets say, 1000 randomly selected New York state residents wheter they are Buffalo Bills fans, and expand this to the entire population of New York State residents.
The population of interest are all residents of New York State.
A simple random sample of 500 students was selected from all the students enrolled in statistics classes.
This means that the population of interest for this student is the students whom are enrolled in statistics classes.
