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.

For which equation is not a solution? x=-1/3

aniked [119]

The answer is B.
We can prove this by putting -1/3 into x.
6(-1/3) - 5 = 7
Multiply -1/3 by 6.
-2 - 5 = 7
Subtract 5 from -2.
-7 $\neq$ 7
So, -1/3 is not a solution to this equation.
Hope this helps!
