Answer:
81.5
Step-by-step explanation:
first arrange the numbers
25,40,68,70,78,85,85,95,98,100
N= 10
median= (n+1)/2
=11/2
=5.5
the average between 5th position and 6th
which is 78 and 85
=(78+85)/2
=81.5
Answer:
8k
Step-by-step explanation:
if you multiply a number and a variable then they combine to make the equation the answer rather than a single number so your answer would be 8k
Answer:

We have to multiply the equation by 100.
Solution:-
We can write 0.03 as 3/100

Hence the answer is 12-x.
Answer:
Step-by-step explanation:
If v = plane velocity and c = air current, then:
v + c = 480
v - c = 400
2v = 880
v = 440
The plane's velocity in still air would be 440 miles per hour.
