Mice eat insects and get eaten by owls. In which case would a population of mice increase? drought keeps grass from growing.

More mice die than are born.

The owl population increases.

The populations of insects increases.

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

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?

Abowling ball rolling down the lane toward the pins has gravitational potential energy. a. no b. a lot of c. a little
