Answer:
data distribution: shows all possible values of data/probability of how often it occurs.
if it is good distribution, the data will be scattered equally in a way which allows you to easily come up with a conclusion upon analysis.
if distribution is poor, the data will not make sense basically.
sorry if this doesn't make sense, i tried to phrase it as best as i could, good luck x
(C) sin(-r) = -a
(D) sin(r) = -a
<u>Explanation:</u>
The unit circle definition allows us to extend the domain of sine and cosine to all real numbers. The process for determining the sine/cosine of any angle θ is as follows:
Starting from (1,0) move along the unit circle in the counterclockwise direction until the angle that is formed between your position, the origin, and the positive x-axis is equal to θ.
- sin θ is equal to the y-coordinate of your point, and
- cosθ is equal to the xxx-coordinate.
In the question, sin(-r) = -a and sin(r) = -a is equal to the x-coordinate, thus they are not correct.

Answer:
100/5-4
Step-by-step explanation:
He spend 100 total, and he spend $5 on each book. So 100/5 would give him how many books total that he bought. If he bought 4 extra you need to subtract that to find out how many books he originally wanted to buy.
