We know that
The t<span>wo roads are the x axis coordinate and y axis coordinate
</span>
therefore
if <span>A hospital is located at the point (−1.25, −5.5)
the distance of hospital from x axis coordinate is the y coordinate---> 5.5 units
</span>the distance of hospital from y axis coordinate is the x coordinate -->1.25 units
the answer are
the distance of hospital from each road is 5.5 units and 1.25 units
Let's represent this unknown number with the variable 'n'
n + n + 2n + 4n = -104
Explanations:
'n+n' - a number plus itself
'+2n' - plus twice itself
'+4n' - plus 4 times itself
Anyway:
n + n + 2n + 4n = -104
Simplify:
8n = -104
Divide both sides by 8:
n = -13
The number is -13
Good luck! If you need me to explain something in more depth, just ask :))

Answer:
Comparing means from dependent samples.
Step-by-step explanation:
In the scenario described above, the 25 sampled individuals were used to test the effect of weightlifting on alleviating back pain. The samples used were not changed nor altered during the study as the same subjects who were tested to measure their level of pain before lifting weight were the same group subjected to the actual weight lifting test and again had their level of pain tested. Since only one group was involved in the study ( a single group was tested on neutral and actual treatment). Hence, the study used dependent samples to compare the average level of pain.
