<span>The list of
scores will be: 30 60 63 65 65 67. To get the median, you have to
arrange the scores from lowest to highest. The middle number is the median. In
this, case there are two numbers in the middle so you have to add the two and
then divide by two.</span>
<span>Therefore, 63 +
65 = 128 / 2 = 64.</span>
That is called square root
First because 5x+5y=0 you can factor the 5
from equation so:
5(x+y) =5 (0) => x+y=0
and by solving for × using elimination method
-8x+y=36
x+y=0
by subtracting both x and y we get
-9x=36 => x=-4
by inputing × into the "x+y=0" equation so we get:
-4+y=0 => y=4
Answer:
625 seconds and 10 minutes
Step-by-step explanation:
distancs=S=5km=5000m
average speed=v=8m/s
time taken=t=?
as we know that
average speed=![\frac{distance covered}{time taken}](https://tex.z-dn.net/?f=%5Cfrac%7Bdistance%20covered%7D%7Btime%20taken%7D)
average speed×time taken=distance covered
here we have to find the time taken
time taken=![\frac{distance covered}{average speed}](https://tex.z-dn.net/?f=%5Cfrac%7Bdistance%20covered%7D%7Baverage%20speed%7D)
time taken=![\frac{5000m}{8m/s}](https://tex.z-dn.net/?f=%5Cfrac%7B5000m%7D%7B8m%2Fs%7D)
time taken=625seconds
now we convert seconds into minutes
![\frac{625}{60}](https://tex.z-dn.net/?f=%5Cfrac%7B625%7D%7B60%7D)
10 minutes
