Explain how you might determine the rate of weathering on a sample rock

Scientists observed a rock stratum with fossil. if mollusks evolved before arthropod, where will their fossils be found.

Consider a normal distribution of frog weights with u = 500 grams and o = 65 grams. a sample of size 2,000 is drawn from this population. approximately how many of the 2,000 cases would you expect to find between 435 and 565?
