500 juniors at RHS took the ACT last year. The scores were normally distributed with a mean of 24 and a standard deviation of 4. Draw a normal curve and label the mean and 3 standard deviations from the mean to help you answer the following questions. a) What percent of scores are between 20 and 28? b) What percent of scores are between 16 and 32? c) What percent of scores are between 16 and 28?

Differential Equations

Have you ever observed the movement of the satellites and rockets or how the planets go around the sun in their orbits? How will you determine their motion? Definitely they follow some scientific laws and these kinds of problems are framed as differential equations.
