Assume v0 is 5.6, v1 is 10.5, and t is 0.5, and write the code to display the average acceleration. # Exercise01_02Extra print((10.5 - 5.6) / 0.5) Chapter 2 Quiz 2.5 #1: Assign 7 to a variable named seven. seven = 7 Quiz 2.5 #2: Define a variable precise and make it refer to 1.09388641. precise = 1.09388641 Quiz 2.5 #3: Define two variables, one named length making it refer to 3.5 and the other named width making it refer to 1.55. ©2020 Pearson Education, Inc., 330 Hudson Street, NY NY 10013. All rights reserved. length = 3.5 width = 1.55 Quiz 2.6 #1 : Variables i and j each have associated values. Swap them, so that i becomes associated with j's original value, and j becomes associated with is original value. You can use two more variables itemp and jtemp . Note: This question does not follow our naming convention for variables. itemp and jtemp should have been named iTemp and jTemp . itemp = i jtemp = j i = jtemp j = itemp Quiz 2.6 #2 : Given two already defined variables, i and j, write a statement that swaps their associated values. i, j = j, i Quiz 2.6 #3 : Given two variables matric_age and grad_age , write a statement that makes the associated value of grad_age 4 more than that of matric_age . Note: This question does not follow our naming convention for variables. matric_age and grad_age should have been named matricAge and gradAge . grad_age = matric_age + 4 Quiz 2.8 #1 : Given the variables taxable_purchases and tax_free_purchases (which already have been defined), write an expression corresponding to t he total amount purchased. Note: This question does not follow our naming convention for variables. taxable_purchage and tax_free_purchase should have been named taxablePurchage and taxFreePurchase . taxable_purchases + tax_free_purchases Quiz 2.8 #2 : Given the variables full_admission_price and discount_amount (already defined), write an expression corresponding to the price of a discount admission. full_admission_price - discount_amount Quiz 2.8 #3 : Given the variable price_per_case , write an expression corresponding to the price of a dozen cases. ©2020 Pearson Education, Inc., 330 Hudson Street, NY NY 10013. All rights reserved. Note: This question does not follow our naming convention for variables. price_per_case should have been named pricePerCase . price_per_case * 12 Quiz 2.8 #4 : Given the variables cost_of_bus_rental and max_bus_riders , write an expression corresponding to the cost per rider (assuming the bus is full). cost_of_bus_rental / max_bus_riders Quiz 2.8 #5 : Write an expression that computes the remainder of the variable principal when divided by the variable divisor . (Assume that each is associated with an int.) principal % divisor Quiz 2.8 #6 : Write an expression that computes the average of the values 12 and 40, and assign it to the variable avg, which has al ready been defined. avg = (12 + 40) / 2 Quiz 2.8 #7 : You are given two variables, both already defined. One is named price and is associated with a float and is the price of an order. The other is total_number and is associated with an int and is the number of orders. Write an expression that calculates the total price for all orders. price * total_number Quiz 2.8 #8 : You are given two variables, both already defined, one associated with a float and named total_weight , containing the weight of a ship ment, the other associated with an int and named quantity , containing the number of items in the shipment. Write an expression that calculates the weight of one item. total_weight / quantity Quiz 2.8 #9 : Assume there is a variable, h already assigned a p ositive integer value. Write the code necessary to assign its square to the variable g. For example, if h had the value 8 then g would get the value 64. g = h * h Quiz 2.8 #10 : Assume that price is an integer variable whose value is the price (in US currency) in cents of an item. Assuming the item is paid for with a minimum amount of change and just single dollars, write an expression for the amount of change (in cents) that would have to be paid.
