The Pythagorean theorem is: a²+b²=c², and "c" will always be the hypotenuse or the longest side of the triangle.
In order to find MN you can make a triangle, and then you can find the lengths of the other sides(a and b).
You should get a = 4 and b = 6. Next you plug these numbers into the equation.
(4)² + (6)² = c²
16 + 36 = c²
52 = c²
√52 = c
Answer:
1) If the order doesn't matter, there are 36 possible outcomes.
2) If the order does matter, there are 181,440 possible outcomes.
Step-by-step explanation:
1) In the case when the order doesn't matter , we have to calculate a combination of 7 screws in 9 holes.
We use the formula for combinations:
being r: the number of screws and n: the number of holes.
2) When the order does matter, the possible outcomes are called permutations. We have permutations of 7 screws in 9 holes.
We use the formula for permutations:
