Answer:
Area 1 is the best option
Step-by-step explanation:
Given Data:
Area 1 = 0.75 dam square
Price = €11,620
Area 2 = 0.009 ha
at €193,500
Area 3 = 0.84a
at €68,900
Where ha ( hectare )
a ( area )
Solution
First we convert all areas to square meter ( m² )
Area 1 = 100 * 0.75 dam square
= 75m²
Cost of area 1/ square meter
= €11,620 / 75m²
= €154.93 / square meter
Area 2 = 0.009 ha * 10,000
= 90m²
Cost of area 2 / square meter
= €193,500 / 90m²
= €2,150 / square meter
Area 3 = 0.84a * 100
= 84m²
= Cost of area 3 / square meter
= €68,900 / 84m²
= €820.23 / square meter
4x^2+6x=12
16x+6x=12
22x=12
x=12/22 or 0.55
The decimal is rounded to the nearest hundreth
Answer:
So the idea is that we want to find the total number of ways that we can pick 7 diamonds (real or fake) from the 12 diamonds.
So as you said, 12 choose 7 = 792
Now we need the total number of ways that we can satisfy that of the 7 we picked, exactly three are real, but this also means that four are fake.
So to choose 3 real from 5 is 5 choose 3 = 10
And to choose 4 fake from 7 is 7 choose 4 = 35
3x10/792= 350/792= 175/396
