Considering that the data is only noted and not changed, this is an example of an observational study.
<h3>What are observational and experimental studies?</h3>
- Experimental study: In an experimental study, there is an intervention in a sample, and it's effect is studied.
- Observational study: In an observational study, the sample is just analyzed, without any intervention.
In this problem, the data, which is the number of miles traveled, is only analyzed, no interventions are made, hence this is an example of an observational study.

If you're talking about inequality graphs, you shade the area where any point in the shaded area can solve the inequality, if I remember correctly. I can't exactly show you how much to shade.
I believe the answer is 2783 for 1 a - either
Answer:
x = 180 - (37 + 53)
Step-by-step explanation:
x + 37 + 53 = 180
x = 180 - (37 + 53)
All of the angles have to equal 180 due to the supplementary angles thm
How to find the mixed number to a fraction:
Let's take 3/2 for instance.
1) You will see how many times the denominator (bottom number) goes into the numerator (top number) in this case that is one time.
2) You will place that number (1) off to the side like so --> 1
3) Then you will see how many parts are left, in this case that is 1 and place that number over the original denominator like so: 1/2
4) Finally you will just combine to get your answer- 1 1/2
Hope I helped,
