Answer:
If the graphs of the equations do not intersect (for example, if they are parallel), then there are no solutions that are true for both equations. If the graphs of the equations are the same, then there are an infinite number of solutions that are true for both equations.
Step-by-step explanation:
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.

Answer:
36 inches of cable weighs 0.68 lbs
Step-by-step explanation:
1178 ft cable weighs 266 lbs...and u want to know how many lbs a 36 inch cable weighs....
we need to turn ur ft to inches....1 ft = 12 inches....so 1178 ft = (1178 * 12) = 14,136 inches
14136 in. to 266 lbs = 36 in.to x lbs
14136 / 266 = 36 / x...cross multiply
14136x = (36)(266)
14136x = 9576
x = 9576 / 14136
x = 0.6774 rounds to 0.68 lbs <===
