Step-by-step explanation:
Equation of given line is:
Thus, the slope of required line is 2.
Step-by-step explanation:
Part C: Of the following choices, which equation is the best fit line for the data
As we can see from the data, the population size are decreased year by year, so the slope of the line of best fit must be a negative number.
So we have: C and D left.
Let x = 0, year 2005, the population size is 296 around 320, hence, we choose D.
D f(x) = -34x + 320
Part D: What is the predicted population size for the year 2010? How does that compare to the real data? Round to the nearest million.
year 2010, x =5 so let substitute x =5 into f(x) = -34x + 320
<=> f(x) = -34*5 + 320
= 150 mil
The result is smaller than the real data, (201-150 = 51 mil)
Part E: In what year is the population predicted to go extinct
the population predicted to go extinct when f(x)= 0
<=> -34x + 320 = 0
<=> x ≈ 9.4
So after 10 years, the the population predicted to go extinct
Answer:
<h2>x + y - 2 = 0</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept.
Put the given y-intercept b = 2 and the coordinates of the point (1, 1) to the equation:
<em>subtract 2 from both sides</em>
The equation of a line:
The general form of an equation of a line:
Convert:
<em>add x to both sides</em>
<em>subtract 2 from both sides</em>
Answer:
15600
Step-by-step explanation:
120x130=15600
20x30=600
& you can work from there if you have to show work
Also you have a nice day too!
