If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up (+1).
If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down (no change).
Answer:
6
Step-by-step explanation:
18.3/3.05=6
18.3 / 6=3.05
Answer:
50°
Step-by-step explanation:
Let measure of one equal side be x.
80° +x +x = 180°[ sum of interior angle of triangle is 180°]
= 2x = 180° -80°
= x = 100°/2
=x = 50°
I'm guessing that [10] refers to the set of the first 10 positive integers.
If the largest element of a given 4-permutation is 6, then the other three elements are pulled from the set {1, 2, 3, 4, 5}. This can be done in 5!/(5 - 3)! = 60 ways. Then there are four possible positions to place the 6, giving a total of 4 * 60 = 240 permutations.
If the largest element of a permutation is *at most* 6, then the maximal element is 4, 5, or 6.
- If it's 4, then there are three other elements available; this can be done in 3!/(3 - 3)! = 6 ways; multiply by 4 to get a total of 24;
- If it's 5, then there are four other elements available, hence 4!/(4 - 3)! = 24 ways; multiply by 4 to get a total of 96;
- If it's 6, then the total is 240.
Putting everything together, the total number of permutations in which the maximal element is at most 6 is 24 + 96 + 240 = 360.
Answer: Statistical
Step-by-step explanation:
I think its statistical because its quantitative data, meaning you can count it.
