Answer:

Option C is correct

Step-by-step explanation:

Given that The owner of a movie theater wants to survey theater customers about their favorite types of movies.

If he surveys every 10th man that will not be a random sample and hence need not represent the population.

If only 25 teenagers are surveyed then opinion would be biased because of their age and will not represent the full population.

C) 50 randomly selected people leaving the movie theater

is the correct method of survey since 50 is a reasonable sample size for public going out from theatre and also all type of people are covered here.

D) 10 women waiting in line to buy movie tickets

is false because they are only women and also they are still waiting to get tickets.

So Option C is right.

A number a decreased by 7 is 2.

umka21 [38]

Answer:

Step-by-step explanation:

Let's first convert this to numbers. When a number is decreased by a certain amount, that is the same as saying that something is subtracted from it. Therefore:

a-7=2

Add 7 to both sides:

a-7+7=2+7

a=9

Hope this helps!

What number increased by 75% is 35

Ne4ueva [31]

To solve this, you would do:

x + 75% * x = 35

7/4 * x = 35

x = 20

Find the equation of a line that passes through the point (3,1) and has a gradient of -3. Leave your answer in the form y = m x

Bingel [31]

Answer:

$y = (-3)\, x + 10$ .

Step-by-step explanation:

The question requires that the equation should be in the slope-intercept form $y = m \, x + c$ . The $m$ and $c$ in this equation are constants. In particular:

$m\!$ would represent the slope of this line (also known as the gradient of this line,) whereas
$c$ would be the $y$ -intercept of this line.

The question states that the slope of this line is $(-3)$ . Therefore, $m = -3$ . Thus, the equation for this line should be in the form $y = (-3)\, x + c$ .

The value of constant $c$ could be found using the other piece of information: the point $(3,\, 1)$ is in this line. In other words, the solution $\text{$x = 3$ and $y = 1$}$ should satisfy the equation $y = (-3)\, x + c$ .

Substitute $\text{$x = 3$ and $y = 1$}$ into the equation $y = (-3)\, x + c$ and solve for $c$ :

$1 = (-3) \times 3 + c$ .

$1 = -9 + c$ .

$c = 10$ .

Hence, $y = (-3) \, x + 10$ would be the slope-intercept form of the equation of this line.
