A. the ratio of boys to girls in a class is 6 to 5 . what is the ratio of girl s to all the students in the class? b. if the ratio of boys to girls in a class is m: n, what is the ratio of girl s to all the students in the class? c. if five elevenths of the class are girls, what is the ratio of girls to boys? a. the ratio, in simplest form, of the number of girl s to the total number of students is 5 : 11 . b. the ratio, in simplest form, of girl s to all the students in the class is nothing : nothing . c. the ratio, in simplest form, of girls to boys is nothing : nothing.

a. Ratio of girls to all students 5:11

b. Ratio of girls to all students n:m+n

c. Ratio of girls to boys 5:6

Step-by-step explanation:

In order to find each of these, we simply need to look at these as a comparison of two data points.

a. In this example, we are looking for girls to all students. We already who there would be 5 girls in the comparison. Then we need to find the whole amount, which is girls + boys (6 + 5 = 11)

5:11

b. In this example, we are looking for girls to all students. We already who there would be n girls in the comparison. Then we need to find the whole amount, which is girls + boys (m + n)

n:m+n

c. In this example, we are looking for girls to boys. We already who there would be 5 girls in the comparison. Then we need to find the boys amount, which is whole - girls (11 - 5 = 6)

5:6

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
