Examine the reasoning in the first two explorations. Can you apply the same reasoning for any nth root, va, where n is a natural number? Explain. What can you conclude?

Which is the correct excel formula for the 80th percentile of a distribution that is n(475, 33)? =norm.dist(80,475,33,1) =norm.inv(0.80,475,33) =norm.s.inv((80-475)/33)?

Question: what is the value of x 4x-2= (-7) +5x. it would be greatly appreciated if someone could actually explain to me step by step
