The correct set of equations is C.

Step-by-step explanation:

m + n = 32

m = 3n

Classify triangle by its<br> Aangles and sides

goldenfox [79]

Answer:

Triangle is a three(3) sided shape i.e it has 3 sides and angles. Triangle can classify based on its side (length and equality) and size of its angles.

Step-by-step explanation:

A, Classification by sides: There are three types of triangle base on sides. These are:

1. Scalene Triangle : This describe triangle that has none of its side to be equal. i.e none of the three sides has no equal length.

2. Isosceles Triangle : This describe triangle that has two of its side equal. Also two of the angles are equal.

3. Equilateral Triangle : This describe triangle that has all its side equal i.e all three sides have equal length. Also all angles are of equal sizes.

B. Classification by size of angle: There are four types of triangle base on classification by angle:

1. Acute Triangle : This describe triangle with all three angles less than 90 degree.

2. Obtuse Triangle : This describe triangle that has one of its angle greater than 90 degree

3. Right Angled Triangle : This describe triangle with one of its angle equal 90 degree.

A graduate class consists of six students. What is the probability that at least 5 of them are born either in April or in Octobe

nlexa [21]

Answer:

0.0671% probability that at least 5 of them are born either in April or in October

Step-by-step explanation:

For each student, there are only two possible outcomes. Either they were born in April or October, or they were not. The probabilty of a student being born in April or October is independent of other students. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$
