Answer: There are 13 gamblers who played exactly two games.
Step-by-step explanation:
Since we have given that
Number of gamblers played black jack, roulette and poker = 5
Number of gamblers played roulette and poker = 8
Number of gamblers played black jack and roulette = 11
Number of gamblers played only poker = 12
Number of gamblers played poker = 24
Number of gamblers who played only roulette and poker is given by

Number of gamblers who played only black jack and roulette is given by

Number of gamblers who played only poker and black jack is given by

So, the number of gamblers who played exactly two games is given by

Hence, there are 13 gamblers who played exactly two games.
The answer is __ because the directions that the truck traveled are basically in the shape of a right triangle. From the warehouse to the airport, that's the slanted line, and from the warehouse to the factory, and the factory to the airport, those are the other lines.
To find the slant line of a right triangle, you want to use the Pythagorean theorem:
a^(2) * b^(2) = c^(2)
c being the slant line
In this case, we want to count how many boxes the other two lines are, then later factor in what units it's in. (meaning later we convert the boxes into miles)
The distance from the warehouse to the factory is 8, and the distance from the factory to the airport is 6. Now, we want to multiply 8 squared by 6 squared to equal c squared.
64+36 = 100
c squared = 100
Next, we have to find the square root of both sides of the equation.
c = 10
This means that there are 10 boxes in between the airport and the warehouse. Since one box = 44 miles, then we multiply our answer by 44 to find the real amount of miles that the truck traveled.
The distance from the warehouse to the airport = 440 miles
The distance from the warehouse to the factory = 352 miles (44*8)
The distance from the factory to the airport = 264 miles (44*6)
Now just add all the values together to find out how many miles in total the truck traveled.
440 + 352 + 264 = 1056
