This probability distribution shows the typical grade distribution for a Geometry course with 35 students. Find the probability that a student earns a grade of A, B, or C. Enter a decimal rounded to the nearest hundredth.

.86

Step-by-step explanation:

There are 5+10+15 = 30 students that earned and A, B or C

P( A, B or C) = number of students that earned and A ,B , C / total

                    =30/35

                    =.857142857

   Rounded to the nearest hundredth

                   =.86

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
