Answer:
The mean no. of red cubes is more than the median no. of red cubes.
Step-by-step explanation:
According to the question, we can prepare the following table denoting the no. of bags containing any number of red cube(s). The no. of red cubes in each bag can theoretically be any no. between 0 and 20 (both end inclusive) as in total each bag contains 20 cubes of different colors.There are as a whole 10 bags (given).
No. of red cubes No. of bags
0 2 0
1 0 0
2 2 4
3 1 3
4 1 4
5 0 0
6 1 6
7 2 14
8 1 8
9 0 0
10 0 0
Total 10 39
Now, no. of bags containing no. of red cubes above 10 is 0 [since there are as a whole 10 bags only]
So, from the table we get that mean no, of red cubes in each bag
=
= 39/10 = 3.9
Also, from the table, we get that, no. of bags with no. of red cubes ≤ 3
= (2 + 2 + 1) = 5
and, no. of bags with no. of red cubes ≥ 4
= (1 + 1 + 2 + 1) = 5
Also there are 1 bag each for no. of red cubes = 3 and 4
So. median no. of red cubes = (3 + 4)/2 = 3.5
So, we get that the mean no. of red cubes is more than the median no. of red cubes.
Answer:
216 people
Step-by-step explanation:
Given:
2.5 feet² is occupied by 1 person
Dimension of room = 216 in × 360 in
Required:
No. of people that would occupy the room
SOLUTION:
Step 1:
Convert the dimensions of the room from in to ft
Note: 1 foot = 12 inches
216 inches =
360 inches =
Step 2: calculate area of the room.
Area of the room = 30*18 = 540 ft²
Step 3: calculate the no. of people the room will contain.
2.5 ft² will contain one person
Therefore, 540 ft² will contain:
