For your question: "A teacher wants to investigate whether listening to music while taking a math test increases scores. He instructs half
of his 36 students to listen to music while taking a test and the other half to not listen to music during the test. To
determine who listens and who does not, the teacher identifies the two students who scored highest on the last test
and randomly instructs one to listen to music and one to not. The teacher does the same for the next two highest-
scoring students and continues in this manner until each student has their instructions. Which of the following best
describes this plan?"
The answer is D
Answer:
x = 5
AB = 26
BC = 39
Step-by-step explanation:
A___B___C
AC = AB + BC
65 = (5x+1) + ( 7x+4 )
65 = 12x + 5
12x = 65-5
12x = 60
x = 60/12
x = 5
AB = 5x +1 = 5(5) +1 = 25 +1 = 26
BC = 7x+4=7(5) + 4 = 35 +4 = 39
I hope I helped you^_^
i believe that the median would be 98.5, because you add the two middle numbers which in this case are 99 and 98 and divide by 2.
Answer:
Option (3)
Step-by-step explanation:
By definition, rigid transformation is a transformation in which size of the object (angles and sides) remains the same.
Option (1).
2 right triangles have identical angle measures but different side lengths.
Since side lengths of the triangle are different so it's not a rigid transformation.
Option (2).
2 right triangles have different angles and side lengths.
Since the triangles are not equal, transformation is not a rigid transformation.
Option (3).
2 right triangle have identical side lengths and angle measures.
Therefore, It's a rigid transformation.
<em>a)</em> The perimeter of question a's shape is 18 units.
