122
The incomplete table above summarizes the number
of left-handed students and right-handed students by
gender for the eighth-grade students at Keisel Middle
School. There are 6 times as many right-handed female
students as there are left-handed female students, and
there are 8 times as many right-handed male students as
there are left-handed male students. If there are a total
of 18-left-handed students and 122 right-handed students
in the school, which of the following is closest to the
probability that a right-handed student selected at random
is female? (Note: Assume that none of the eighth-grade
students are both right-handed and left-handed.)
A. 0.613
B. 0.541
C. 0.410

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.

step-by-step explanation:

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to
