Answer:
x + 4y ≤ 15; y ≥ 0
Step-by-step explanation:
The graph doesn't do a very good job of modeling any of the given equations. However, the equations listed above seem the best fit.
The slope of the top (left) line is negative, so the equation will be of the form ...
x + 4y = something
When y=0, x=15, so the "something" is expected to be 15.
However, the line appears to go through points (6, 2) and (-2, 4). Both of these points are on the line x + 4y = 14.
The graph is shaded <em>below the line</em> so the values of x and y that are in the shaded area will add to <em>less than</em> 15 (or 14). Hence, the inequality will be ...
x + 4y ≤ something . . . . . part of the 3rd answer choice
The fact that the shading does not go below y=0 means the other limit is ...
y ≥ 0 . . . . . part of every answer choice.
Answer:
A) <u>7 : 13</u> is the ratio .
B) <u>69.65 million </u>approve of George W. Bush.
Step-by-step explanation:
Given:
The results of a recent survey of 1500 American adults show that 525 approve of the job that President George W. Bush is doing and 975 do not approve.
Now, to find the ratio of the people approve to those that do not. And number of people approve of George W, if there are 199 million adults in the United States.
<h2>A)</h2>People approve of the job = 525.
People do not approve of the job = 975.
So, the ratio of that approve to those that do not:
<em>On simplifying it:</em>
Thus, the ratio is 7 : 13.
<h2>B)</h2>If the adults in the United States is 199 million.
Let the people approve be
According to survey 525 out of 1500 approve of the job.
So, 525 is equivalent to 1500.
Thus, is equivalent to 199,000,000. (1 million = 1,000,000.)
Now, to solve by using cross multiplication method:
<em>By cross multiplying we get:</em>
<em /><em />
<em>Dividing both sides by 1500 we get:</em>
Thus, number of people approve are 69.65 million.
Therefore, 69.65 million approve of George W. Bush.
