When the number of data points is odd the formula to find the Ranking of the Median is (n+1)/2, When the number of data points is even the ranking of the Median will be the AVERAGE of n/2 + n/2 +1, where n is the number of data points.
In our case the ranking of the Median is the average (20+21)/2 = 20.5.
1- How many points are below the Median =20
Lower half = 20, Upper half = 20 & Median = 20.5 (Don't forget Median is the ranking of data points).
Again the 1st Quartile is at 10.5, so 10 data points are below the 1st Quartile
and 20 points are between Q1 & Q3
Answer:
Step-by-step explanation:
<u>The speed is:</u>
<u>To find:</u>
- Distance in 1 minute and 2 seconds
Distance = speed * time
<u>Distance is:</u>
- 100/9 meter /seconds * 1 min and 2 seconds =
- 100/9 m/s *62 s =
- 6200/9 m = 688.88 m ≈ 689 m rounded to the nearest meter

They are vertical angles meaning they both have the same angle thus you can set the two equations equal to each other
9y+7 = 2y+28
Solve for y
Plug your y into one of the equations and you’ll get your angle

Answer:the unit rate is $0.5
Step-by-step explanation:
Andre rents a bike for a day. The rental changes can be determined by the equation: R = $0.5d, where R is rental changes and d is number of days she rents the bike.
The unit rate multiplied by the number of days for which the bike was rented would give the total rental charge. From the given equation, the unit rate would be $0.5
