Step 1) Sort the data values. Since the data is already sorted for us, we can skip to step 2
Step 2) Identify the median of the given data set. The median is the middle most value. In this case, its the value 80 which is in the 4th slot. There are 3 values to the left of the median, and there are 3 values to the right of the median.
Step 3) Break the given data set into two halves such that the lower half data set is L = {36, 45, 79}
Notice how everything in set L is the set of values smaller than the median found back in step 2
Step 4) Find the median of set L. The median of this sub-set is 45
The median of the lower half of data values is the first quartile Q1.

Final Answer: 45
185:235. Since the ratio is referring to oranges first and then bananas, those numbers would get plugged in that order.
Answer:
The minimum volume of hot air needed to lift a hot air balloon carrying 800kg
Is 653.1m³
Step-by-step explanation:
This problem bothers on the density of materials in this problem air
Given data
Volume of air V=?
Mass of air m= 800kg
From tables the density of air is
ρ =1.225 kg/m3
Now to solve for the volume we have
ρ=m/v
v=m/ρ
v=800/1.225
Volume v = 653.1m³
Answer:
the correct answer is A
