If you illustrate the problem, the parallelogram will look like this with the following coordinated (see picture).
The k must be the x-axis while h must be the y-axis. The y-coordinate of the unknown must be j because it is aligned with the upper right corner. By definition, a parallelogram is a quadrilateral with two equal, parallel sides. Hence,you also have two sets of equal angles. It also means that the distance of the upper and bottom corners of the left side and the right side are equal. Through symmetry, the x-coordinate is the distance between h and k.
Thus, the unknown coordinates are
(h-k,j)
You can break it down into a bunch of squares and rectangles. Find those areas and add them up.
The total area is :
7*10 + 5*5 + 4*12 = 143
Answer:$90
Step-by-step explanation: 5x15=75
5x3=15+75=90
Using the interpretation of the confidence interval, the correct option is:
We are 95% confident that those who studied had a higher passing rate than those who did not study.
<h3>What is the interpretation of a x% confidence interval?</h3>
It means that we are x% confident that the population parameter(mean/proportion/standard deviation) is between a and b.
The confidence interval of the difference is:
(0.005, 0.125).
Since the entire interval is positive, the correct option is:
We are 95% confident that those who studied had a higher passing rate than those who did not study.

- Slope-Intercept Form: y = mx + b, with m = slope and (0,b) as the y-intercept.
So starting with the y-intercept, the easiest method to find it is to convert this standard form equation to slope-intercept form. Firstly, add 5x to both sides:

Next, divide both sides by -4 and your slope-intercept form is 
Looking at this slope-intercept form, <u>the y-intercept is (0, -5/2).</u>
Now to find the x-intercept, just set the y-variable to zero and solve:

<u>Our x-intercept is (-2,0).</u>
