For question 1, it is important to know the vertical angles are angles that are equal to each other because they are congruent and are "across" from each other when two lines intersect. Therefore, you can set an equation where one side is equal to the other as you are solving for x, which would be 2x=x+30. You may then solve this equation like any other equation based on mathematical properties and operations, whereas this is how you may do question #1.

Leviafan [203]

Answer:

0.157 is the proportion of students who smoke.                                        

Step-by-step explanation:

We are given the following in the question:

Number of students who smoke = 58

Number of students who don't smoke = 311

Total number of students surveyed =

Number of students who smoke + Number of students who don't smoke

= 58 + 311\\=369

Proportion of students who smoke =

=\displaystyle\frac{\text{Number of students who smoke}}{\text{Total number of students}}\\\\= \frac{58}{369}\\\\= 0.157

Thus, 0.157 is the proportion of students who smoke.
