Last year 120 students were sick at school this year 20% fewer students are sick how many students are sick this year

96 students

Step-by-step explanation:

Since we are comparing last year to this year, the number if sick students last year would be 100% (or original number of sick students)

Percentage number of students sick this year

= 100% - 20%

= 80%

Note that the percentage of sick students this year is not 20% because of the word 'fewer'.

Number of sick students this year= 80/100 × 120= 96

Or you could also think of it this way:

100% 120 students

80% 120/100 × 80= 96 students

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'.

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.
