The significance of 160,000 in the function is the initial population at the time of the estimation.

The correct option is (C)

<h3>What is data?</h3>

A collection of facts, such as numbers, words, measurements, observations or even just descriptions of things.

Given:

As per the table attached below:

F(x) signify the total population when the time was x hour.

So,  160,000 in the function signifies that the population at starting i.e., initial point.

Take 2 points
(3, 9) and (0, 3)
Slope = (Y2 -Y1) ÷ (X2 -X1)
<span>Slope = (3-9) / (0-3)
</span><span>Slope = -6 / -3
</span><span>Slope = 2

The equation will have the form    </span><span>y = mx + b</span>
We can rearrange this to   b = y -mx
Let's take one of the points (3, 9) and the slope (m) and enter it into the formula:
b = -9 -2*3
b= -3
Now we enter all that data into b = y -mx
and get
y = 2x -3

Survey data indicate that 42% of customers at Mega Hit video rental stores subscribe to premium movie channels through their cab
omeli [17]

Answer:

P=0.17

Step-by-step explanation:

If A and B are dependent events, then we have a Rule of Addition:

P(A\cup B)=P(A)+P(B)-P(A\cap B)

Let A represent event that customer at Mega Hit is subscribed to premium movie channels while B represent event that customer at Mega Hit owns a DVD, so, we get the following:

P(A)=0.42\\P(B)=0.31\\P(A \cup B)=0.56\\\\

We need to find P(A \cap B) or probability that a randomly selected Mega Hit customer both owns a DVD and subscribes to a premium movie channels.

Using Rule of Addition, we get:

0.56=0.42+0.31-P(A \cap B)\\\\0.56=0.73-P(A\cap B)\\P(A\cap B)=0.73-0.56\\P(A\cap B)=0.17

So, the required probability is 0.17.

<h2>Answer:</h2><h3>For each of these, we use PEMDAS (parenthesis, exponent, multiplication, division, addition, subtraction, IN THAT ORDER).</h3>

#11:

2(6k - 1) = -32\\\\12k - 2 = -32\\\\12k = -30\\\\k = -2.5

#12:

15 = -3(x - 1)\\\\15 = -3x + 3\\\\12 = -3x\\\\-4 = x

#13:

7x + 6x - 3x - 45 = 15x\\\\10x - 45 = 15x\\\\-45 = 5x\\\\-9 = x

#14:

3x + 5 = \frac{1}{2}(4x + 28)\\\\3x + 5 = 2x + 14\\\\x + 5 = 14\\\\x = 11

#15:

10 - (x + 5) = 2x + 14\\\\10 - x - 5 = 2x + 14\\\\5 - x = 2x + 14\\\\5 - 3x = 14\\\\-3x = 9\\\\x = -3

#16:

\frac{2}{5}(10x - 15) = -14\\\\4x - 6 = -14\\\\4x = -8\\\\x = -2

*Note: You can check my work by pluging in each result I got for x back into the equation and solve. If both numbers on each side of the equal sign match, that means I'm right.
