Decision alternatives are structured so that several could occur simultaneously. Group of answer choices True False

False

Explanation:

It is false because the range of designed alternatives reflect solid different approaches or priorities across objectives, presenting decision makers with real options and choices.

Decision trees are well-known representations of Boolean functions, the  decision alternatives structure has a statement or a set of statements that are considered “true”. When the Boolean expression determines it as "true", the statement or set of statements of the structure is executed, if this doesn´t happen then the statements are skipped.

25 meters

Step-by-step explanation:

in this case they give us the information about the lake and that length corresponds to the perimeter.

the perimeter of a circle has the following formula:

p = 2 * pi * r

then r equals:

r = p / pi * 2

replacing we have:

r = 157 / (2 * 3.14)

r = 25

which means that the radius of the lake is 25 meters
