Answer:
Step-by-step explanation:
The third quartile is at 75% of total of number of students.
So percentage score great or equal to this is 25%.
We will have to use the formula for the area of a trapezoid on this problem, which is ( and are the bases of the trapezoid and is the height):
All we need to do is substitute the information we are given into our formula:
Now, let's just simplify the equation:
The missing base has a length of 13 units.
Answer:

The graph would look something similar to this:
Answer:
(-3, 0)
(0, 3)
(1, 4)
Step-by-step explanation:
It’s easier if you make an equation like this!
Start by finding the slope using two points
m = slope
m = y2 - y1/x2 - x1
For right now, I’m going to have to use two points from the graph.
Points: (-5, -2) and (0, 3)
m = 3 - -2/0 - -5
m = 5/5
m = 1
Now find the y-intercept (located where x coordinate is 0)
y-intercept = 3
Now make the equation of a line that has a slope of 1 and a y-intercept of 3
y = x + 3
Now use any point to see if it is a point on the graph.
y = x + 3
Point: (2, 5)
5 = 2 + 3
5 = 5
Therefore it is a point
y = x + 3
Point: (-3, 0)
0 = -3 + 3
0 = 0
y = x + 3
Point: (2, 4)
4 = 2 + 3
4 = 5
That comes to sin 3 theta + cos 3 theta + 2 sin theta cos theta + 1
