Match the scenario to the term it represents. 1. A scientist records Star C's age based on the distance he determined it to be from earth.

2.A scientist records data for Star X in January and again in June of the same year.

3.A scientist records color data for Star Q.

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error

What is the rate of change in a objects position?

Rank the automobiles based on the magnitude of the force needed to stop them, from largest to smallest.2000 kg car going 5m/s500 kg car going 20 m/s1000 kg car going20m/s500 kg car going10m/s1000 kg car going10/s4000 kg car going 5m/s 0 0 603
