Suppose you have Avogadro\'s number of mini marshmallows and use them to cover the state of Oregon which has a land area of 9.600 × 104 mi2. Each mini marshmallow has a diameter of 0.635 cm and a height of 2.54 cm. Assuming the marshmallows are packed together so there is no space between them, to what height above the surface, in kilometers, will the mini marshmallows extend?

Draw the cache tables and the state of all bits within them. Suppose you have a 16 byte cache with 2 byte long cachelines that is 2-way set associative and write-back. Further assume that prior to processing any read/write requests the state of memory is M[a] = a, or another words, the byte at address 0 is 0, address 1 is 1, address 2 is 2, and so on. Assume an *8 bit* long address. Along with depicting the cache...

6. There are 40 books on a bookshelf. Exactly 10 of them have a red cover. The remaining books have a white cover. You intend to choose a random sample of nine books, but you haven't decided whether to choose with replacement or without replacement? a) If you choose books with our placement, would this procedure lead to independent trials or dependent trials? b)if you choose books with replacement, would this procedure be consistent with a binomial experiment or not?...

Use pd.crosstab() to count the number of regions of each cover type there are for each of the 40 soil types. Pass this function the Cover_Type column as its first argument and the Soil_Type column as the second argument. Store the results in a DataFrame named ct_by_st and then display this DataFrame. soil = np.unique(fc['Soil_Type']) palette = ['orchid', 'lightcoral', 'orange', 'gold', 'lightgreen', 'deepskyblue', 'cornflowerblue'] Perform the following steps in a single cell: 1. Start by converting the count information into...

State the number of friends (or connections) that you have on Facebook (or Linkedin). In case you have more than 365 friends or connections, think of an alternative, smaller group of friends or relatives. What is the chance that there are at least 2 people among your friends (or connections) with the same birthday (same day, not same year)? Let's find out. Please respond with an estimate of the probability that this will happen. This estimate can be intuitive or...
