Use the information below to answer questions 6-10.The table below shows some data collected over 22 weeks about the depth of water in a reservoir.  The equation for the regression line and the correlation coefficient are given as well.Use the regression line equation to predict the depth of water at t=20 weeks.  Do not round your answer

The water in a tank is drained out at a constant rate. The relationship between the depth of water in the tank, d cm, and time, t in seconds, is given 3d=-6t+210. Determine the initial depth of water in the tank.

A submarine is at a depth of 100 feet below sea level. Then it starts to dive at a rate of 50 feet per minute.Question 1A. For this situation, what is the independentvariable (include units)?B. What is the dependent variable (include units)?C. What is the slope of the line that models thissituation?D. What is the y-intercept of the line that modelsthis situation?Question 2Write the equation of the line that models thesituation using the slope and y-intercept found inparts C and D of question 1.

Calculate the amount that the pumped water would raise the level of the dead sea by every year assume that there is no loss of sea level by other means.  use volume = surface area x length

If the lines of regression of sample are x + 6y = 6 and 3x + 2y = 10.Find i) mean of x & y andii) correlation coefficient between x and yiii) estimate y when x = 12

A long jump competition took place recently at a local high school. The coach is interested in performing as well as possible in the next competition, so he is looking at the relationship between height and distance jumped (both measured in inches). He uses height to predict distance. The data was analyzed to produce the following regression line: What is the correlation coefficient?
