Answer:
First 25% 10 - 22.5
Next 25% 22.5 - 35
Third 25% 35 - 47.5
Last 25% 47.5 - 60
Step-by-step explanation:
First get the median of the entire data.
From the median, you split the data into two and find the median for both sections.
Finally, your smallest median is your first 25% and so on.
I believe the answer is either 5 or -1.5
4n - 7 = 13
7 - 4n = 13
4(5) - 7 = 13
7 - 4(-1.5) = 13
4(5) - 7 = 13
Slope is already given in the question so we only need to solve for the y-intercept.
Slope intercept form: y = mx + b
m = slope
b = y-intercept
-3/5 = -0.6
1 = -0.6(1) + b
1 = -0.6 + b
1 + 0.6 = -0.6 + b + 0.6
1.6 = b
Now, write in slope-intercept form.
y = -3/5x - 1.6

6.4x + 2.8y = 44.4
6.4(3) + 2.8y = 44.4
19.2 + 2.8y = 44.4
-19.2 -19.2
2.8y = 25.2
------ ------
2.8 2.8
y = 9
That is a ratio. 7 x 3 = 21 and 13 x 3 = 39.
