It seems that the question above is incomplete. I believe the complete statement would be written as:
When placed in a 100 mL cube-shaped box, a substance fills the cube and has a volume of 100 mL. When placed in a 50 mL tube, that same amount of substance fills the tube and thus has a 50 mL volume. What is the state of the substance?
From the statement, most likely, the substance is a gas since the volume it takes is the same as its container. Gas is the only phase that could take up the whole volume of its container given a certain mass.
This is true a polygon with 12 sides is called a dodecafon.
Answer:
0.9007 is the probability that a student scored below 86 on this exam.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 77
Standard Deviation, σ = 7
We are given that the distribution of examination grades is a bell shaped distribution that is a normal distribution.
Formula:

a) P(student scored below 86)
P(x < 86)
Calculation the value from standard normal z table, we have,

0.9007 is the probability that a student scored below 86 on this exam.
