Two cars are moving towards an intersection. One car is 160 meters north of the intersection and moving towards the intersection at 15 m/s, while the other is 120 meters west of the intersection and moving away from the intersection at 20 m/s. 4 seconds later, the cars are getting (farther apart/closer together)at _____m/s. (Enter your answer rounded to three decimal places).

Inverse Normal Distribution

The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.

Mean, Median, Mode

It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.

Z-Scores

A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
