When finding the area of a triangle, you always divide the product by 2 because a triangle is half a square.
Answer:
Geometric sequence.
Step-by-step explanation:
Simply defined, a complex sequence is a set of numbers in a sequence, whose numbers include imaginary numbers. In essensce, not all numbers in a complex sequence are real numbers.
A geometric sequence is a sequence in which each number must be multiplied by a number (referred to as the common ratio) to attain the next value in the sequence.
An arithmetic sequence is a sequence of numbers in which one has to add a value to the previous number to attain the next number.
A simple sequence can be defined as a pattern of numbers, such as a list of multiples.
In the given sequecne:
3, 9, 27, 81, 243
One can see that each element is three times the last. Diving any two consecutive elements (elements next to each other) will result in the numerical value of (3). Therefore this is a geometric sequence since it fits all of the criteria of a geometric sequence and even has a common ratio of (3).
36 equally-likely outcome: (1,1), (1,2), (1,3), (1,4), (1,5), (1,6), (2,1), (2,2), (2,3), (2,4), (2,5), (2,6), (3,1), (3,2), (3,3), (3,4), (3,5), (3,6), (4,1), (4,2), (4,3), (4,4), (4,5), (4,6), (5,1), (5,2), (5,3), (5,4), (5,5), (5,6), (6,1),(6,2), (6,3), (6,4), (6,5), (6,6)
Solution:
Outcomes with first number being old number and second being even number: (1,2), (1,4), (1,6), (3,2), (3,4), (3,6), (5,2), (5,4), (5,6) = 9 outcomes
P(old,even) = 9/36 =1/4 = 0.25
