Answer:

F

Step-by-step explanation:

We can use a proportions to solve this problem:

time of researches (in percentages 100% is used to indicate the total)

5 : 100 = x : 30

x = (5 * 30)/ 100 = 1.5

time of games

25 : 100 = x : 30

x = (25 * 30)/100 = 7.5

7.5 - 1.5 = 6 hours

Answer:

Crazy boy [7]
I think the possible way that the percentage vote of a country is different to the next random sampling to the other data table is its population in each country. In the first table i think Malta has the edge to this table data and place in number 1 but to the other data table the country was left of.

What is the value of the function when x = 1?
creativ13 [48]

On the graph, we can see that when x=1, y=0.

But we don't even need to bother opening the attachment
and studying the graph !

In your question, you said that one point on the function is  (1, 0) .
That means that when 'x' is 1, 'y' is zero.  And there you are !

What is y-intercept of the graph
Kipish [7]

Answer:

  1a. y-intercept: 12

  1b. slope: -3/2

  1c. equation: y = -3/2x +12

  2a. y-intercept: -9

  2b. slope: 2

  2c. equation: y = 2x -9

Step-by-step explanation:

<h3>1.</h3>

A) We observe the pattern to be <em>x-values in the table increase by 2, while y-values in the table decrease by 3</em>. We notice the first x-value is 2, so extending the table upward to x=0 would tell us the y-intercept. That is, adding 3 to the first y-value will give the y-intercept as (x, y) = (0, 12).

B) We have already observed that the "rise" (change in y) is -3 for each "run" (change in x) of 2. The slope is the ratio of these changes:

  slope = m = rise/run = -3/2

C) From the above, we know that m=-3/2 and b=12. Putting these values into the equation for the line gives ...

 y = -3/2x +12

__

<h3>2.</h3>

A) We observe the pattern to be <em>y-values increase by 2 while x-values increase by 1</em>. As before, we can find the point that would go before the first one shown in the table. It will have an x-value of 0 and a y-value of -9.

  the y-intercept is -9

  the slope is 2/1 = 2

  the equation is y = 2x -9
