Answer:

B) randomly select people from all residents of the apartment building

Step-by-step explanation:

First let's see what a sample is.

Sample is nothing but taking a few people for a survey from the entire population. When want to take the survey we cannot ask the opinion of the entire population. We take a few people from the group, ask their opinion and draw for a conclusion for the entire group.

In this case, to building a pool in the apartment, we take a few from the apartment and ask their opinion.

Therefore, answer is B) randomly select people from all residents of the apartment building

Hope this will helpful.

Thank you.

Find the equation of the line through (0,4) perpendicular to the line y = 3x

Rufina [12.5K]

Answer:

$y = - \frac{1}{3} x + 4$

Step-by-step explanation:

The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.

The product of the gradients of perpendicular lines is -1.

Gradient of given line= 3.

(Gradient of line)(3)= -1

3m= -1

m= $- \frac{1}{3}$

subst. m= $- \frac{1}{3}$ into the equation:

$y = - \frac{1}{3} x + c$

To find the value of c, substitute a coordinate.

When x=0, y=4,

$4 = - \frac{1}{ 3} (0) + c \\ 4 = c \\ c = 4$

Thus the equation of the line is $y = -\frac{1}{3} x + 4$ .

" 6x > 12 " ;

Solve in terms of "x" :

______________________________________________________

Divide each side of the inequality by "6" ;

to isolate "x" on one side of the inequation; & to solve in terms of "x" ;

→ " 6x / 6 > 12 / 6 " ;
