If 100 students make up 40% of the 6th grade population, then 50 students make up 20% of the 6th grade population. 20% × 5 makes 100% so if your multiply 50 by 5 you'd get your population.
50 × 5 = 250 sixth-graders

Answer:
Step-by-step explanation:
Z-score:
In a set with mean 
and standard deviation 
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question:
You listen to the radio station for 1 hour, at a randomly selected time, and carefully observe that the amount of advertising time is equal to 17 minutes. Calculate the z-score for this amount of advertising time.
We have to find Z when X = 17. So
Answer:
Swing two arcs above and below the radius.
Step-by-step explanation:
We want to determine which statement is NOT a step used when constructing an inscribed hexagon?
1. Swing two arcs above and below the radius.
False
2. Draw a radius of the circle using a straightedge. True
3. Place the compass on the point where the circle and radius intersect. True
4. Swing an arc the length of the radius from the point on the circle. True
The first choice is the correct answer.
