Mr. Johansen has just finished grading a test he had given to his 5th period history class. Overall, he feels that the class
did pretty well, knowing that two students earned a 100% and at least half of the class scored a 78% or better. But, Mr.
Johansen also knows that there are a few very low scores in the 40% -50% range that will lower the average.
In order to get a good picture of his class's performance on the test, Mr. Johansen plans to create a box-and-whisker
plot to summarize the test results. Based on what he already knows, which of the following plots is most like what Mr.
Johansen should expect for his 5th period history class?

answer: a.   one is a factor of every whole number since every number is divisible by itself.

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

well

44-3-3-3=35

35+4+4+4+4=51

so the ansewr would be 51 degreesat 7: 00
