<span>Residents who are under 25 years and those above are mutually exclusive.
Let V = number of persons who take Vanilla under 25yrs and V' be the number of residents who are at least 25yrs who take Vanilla.
Okay, so P(V) = 40/150 and P(V') = 15/150
P(V or V') = 40/150 + 15/150 = 0.366</span>

Answer:
The answer is below
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. Types of triangles are isosceles, acute, scalene, obtuse, right and equilateral triangle.
A scalene triangle is a triangle in which all the three sides of the triangle have different lengths hence, all the angles of the triangle also have different lengths.
Therefore the set of straw lengths that can be used a scalene triangle must have different lengths, for example:
5, 7 , 8
You divide 240 miles by 6 cm so you can figure out how many miles are in each centimeter. So 240/6=40 miles. The scale is for every one centimeter, that is 40 miles.
