Consider the two following random arrays "a" and "b": (10 points) a = np.random.randn (2, 3) # a.shape = (2, 3) b = np.random.randn (2, 1) # b.shape=(2, 1) c = a + b What will be the shape of "c"?

import numpy as np a = np.array([1,2,3]) b = np.array([4,5,6]) You may need to use NumPy methods to answer the following questions. What is the cross product of the two vectors a and b given above? What is the dot product of the two vectors a and b given above?

Given an array of wine objects, write a function that returns the name of the wine he will buy for the party. If given an empty array, return null. If given an array of only one, Atticus will buy that wine. Examples chosenWine ([ { name: "Wine A", price: 8.99 }, { name: "Wine 32", price: 13.99 }, { name: "Wine 9", price: 10.99 } - "Wine 9" ])
