1. There are 10 ducks in total, 5 in each pool.
2. For each pool, the probability of picking a certain numbered duck—for instance, #3—is 20%.
3. Because the pools are separate with, picking one duck from one pool does not affect the chance of picking a certain duck from the other pool.
4. Therefore, the probability that a contestant wins the game is 20%.
Good luck!
Answer:
40% I think because it is easy to turn a number into percentage.
Area = 32 units^2. Formula for a right angle triangle is Length x Width x 1/2. The biggest triangle is 4 x 10. Put that into the formula you get 4 x 10 x 1/2 which equals 20. Medium triangle is 2 x 6. In the formula it’s 2 x 6 x 1/2 = 6. Small triangle is 2 x 2. In the formula it’s 2 x 2 x 1/2 = 2. And the small square is 2 x 2 which you multiply normally to equal 4. Now add them all up to get 32 units^2
Answer:
C
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
(7x - 40) is an exterior angle of the triangle, then
7x - 40 = 3x + 3x - 20
7x - 40 = 6x - 20 ( subtract 6x from both sides )
x - 40 = - 20 ( add 40 to both sides )
x = 20 → C
