Answer:
Step-by-step explanation:
<u>The ratio is given:</u>
<u>Let each equal part be x, then we have:</u>
- b - r = 6
- 9x - 6x = 6
- 3x = 6
- x = 2
<u>Total number of counters:</u>
- 2(9 + 6 + 3) = 2(18) = 36
Step-by-step explanation:
Let,
Blue counter = 9x
Red counter = 6x
Yellow counter = 3x
Given,
9x = 6x + 6
9x - 6x = 6
3x = 6
x = 6/3
x = 2
Now,
Total number of counter = 2(9) + 2(6) + 2(3)
=> 18 + 12 + 6
=> 36

Answer:
Step-by-step explanation:
=> 5x-4+2(x-4) = 16
Expanding the brackets
=> 5x-4+2x-8 = 16
Combining like terms
=> 5x+2x-4-8 = 16
=> 7x - 12 = 16
Adding 12 to both sides
=> 7x = 16+12
=> 7x = 28
Dividing both sides by 7
=> x = 4
I would say to do 637000-437000, which is 200000, and then do 200000/637000. You get 0.314, and the percentage of that in hundreds is 31%.
The outlier is 68
The median is 102
First quartile: 87
Third Quartile: 115
The interquartile range is 87-115
