Answer:
5:6
five of the 6 students are girls
5/6
Step-by-step explanation:
Not sure if these are the three different ways you wanted, but all of these represent the number of girls compared to the total number of students.
The absolute value of 7 and 1/8 is 7 and 1/8! If you have to add these two values then it would be 7 1/8. Absolute value just means both values will be positive. Hope this helps!

Answer:
Step-by-step explanation:
This fraction represents the area under the standard normal curve between 60 and 65 points. This represents the area from the mean (60) to one standard deviation above the mean (65). The applicable z-score is
65 - 60
z = --------------- = 1.
5
The problem then involves finding the area under the curve from z = 0 (that is, the mean) to z = 1 (one standard deviation above the mean).
Refer to the "empirical rule." This rule states that 68% of data lies within one standard deviation of the mean, that is, within z = -1 and z = 1. We are interested only in the area that is within z = 0 and z = 1, which is half of 68%, and thus is 34%.
In summary, approx. 34% of students have scored between 60 and 65 points.
