Agroup of 120 seventh- and eighth-grade students were asked whether they participate in sports or in non–sports-related activities. the two-way table shows their answers.

participation in sports or non-sports

which statement is correct?

twenty-nine seventh-grade students chose a sports activity.
twenty-eight eighth-grade students chose a sports activity.
twenty-four seventh-grade students chose a non-sports activity.
thirty-nine eighth-grade students chose a non-sports activity.

Option 3. is the answer.

Step-by-step explanation:

For Option 1. Not true because 39 seventh grade students chose a sports activity.

For Option 2. Not true because 29 eighth grade students chose a sports activity.

For option 3. True as 24 seventh grade students chose a non sports activity.

For option 4. Not true because 28 eighth grade students chose a non sport activity.

Option 3. is the answer.

eve and marks ratios are equivalent

step-by-step explanation:

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'.
