A race car increases its speed from 11 m/s to 53 m/s during  a 7.0 s  time interval.  What is its acceleration?  

Explain how stopping and starting in a car can both be used as examples of inertia.    

A heavy object and a light object are dropped from rest at the same time in a vacuum. The heavier object will reach the ground

A boy on a skateboard pushes off the ground with his foot. He and the skateboard accelerate down the sidewalk due to the force

Find the heat required to raise the temperature of 450.0 g of water from 20.0oC to 45.0oC.

The following scatterplot is constructed from major and minor axis measurements from a sample of 100 raisins. The overlying curves correspond to 68%, 95%, and 99.8% prediction ellipses. What does this plot suggest about the assumption of bivariate normality of this data set? Explain your answer by referring to relevant characteristics of the plot.

Match the correct term to each statement.

The acceleration of gravity near the surface of Earth is 9.8 m/s2.

Water and mosquito fish samples were collected at a sample of 96 sites in the Florida Everglades in the spring of 1996. The confidence intervals below are for the means of totalmercury (thg), methyl mercury (mehg), and turbidity (turbid). Each interval is calculated at the individual 90% confidence level. Lower CI limit Upper CI limit thg 0.67 1.16 mehg 0.50 0.81 turbid 1.44 4.15   (3pts) What is meant by “individual” 90% confidence here? How is this different from “simultaneous” confidence? (3pts) If these intervals—without modification—are to be interpreted simultaneously, what confidence level would be applied to them?
