Optimize the the cutoffs for Petal. Length and Petal. Width separately in the train dataset by using the seq function with increments of 0.1. Then, report the overall accuracy when applied to the test dataset by creating a rule that predicts virginica if Petal. Length is greater than the length cutoff OR Petal. Width is greater than the width cutoff, and versicolor otherwise.

Calculate the minimum energy required to remove one proton from the nucleus 126c. this is called the proton-removal energy. (hint: find the difference between the mass of a 126c nucleus and the mass of a proton plus the mass of the nucleus formed when a proton is removed from 126c.) express your answer with the appropriate units. emin e m i n = nothing nothing request answer part b how does the proton-removal energy for 126c compare to the binding energy per nucleon for 126c, calculated using eb=(zmh+nmn−azm)c2?
