To find the median cancel out numbers on both sides, until one is left in the middle and if there are two in the middle add them up and divide by two.
So in this case the median is
53+78
131 / 2
65.5
7 tenths is 0.7. The fraction form is 7/10, since the digit of 7 is in the tenths place.
I hope this helps, please Brainliest me, and have a great day! :D
53 races are needed to finish.
<h3><u>Determination of quantities</u></h3>
Given that 271 sprinters enter a race, and the track has 7 lane so only 7 can compete at a time, and at the end 6 non winners are eliminated and the winners race in a later race, to determine how many races are needed to finish the following calculation must be performed:
- 271 / 7 = 38.71 (39)
- 39 / 7 = 5.57 (6)
- 45 / 7 = 6.42 (7)
- 7 / 7 = 1
- 39 + 6 + 7 + 1 = X
- 53 = X
Therefore, 53 races are needed to finish.

15 divide by 3 equals 5
15 is equal to 3 units
1 unit equal to 5
15 plus 5 equal to 20
Answer:
5
Step-by-step explanation:
[2 3]
[1 4]
The determinant of the above matrix can be obtained as follow :
|2 3|
|1 4|
= (2×4) – (1×3)
= 8 – 3
= 5
Thus, the determinant of the metrix is 5
