In a population of toads, average body length is 30mm. Body length is variable and the narrow sense heritability for body length is 0.1 for this population. You cross a male of 20mm with a female of 22mm. In order to determine the expected average offspring length, what do you multiply with your heritability?

In 1991 the Zambian Government began economic reforms which included the transport sector. The reforms in the transport sector resulted in the abolishment of parastatal companies like United Bus Service of Zambia, Mulungushi Bus Service, Zambia Airways and Contract Haulage to mention just a few. Your assignment is as follows;

  1. Discuss how the reforms have affected the transport sector overall, in the passenger and freight transport. Conduct literature review about the transport reforms from the UNIP government policy perspective to the MMD government transport reforms.
  2. Explain how a regulated transport sector and deregulated transport sector operate, what role does government play to ensure that there is transportation equity in the provision of the service.
  3. Explain how cartels can distort the market functioning in the transport sector (Demand and supply).
  4. Give your general observations about these reforms and what would be your recommendation to improve the current transport sector performance.

A four legged sling distributes its load equally among its four legs. When the load is picked up, each leg forms 45° with the horizontal. The nominal breaking strength of the chain is specified to be 10 tons. If the load that is carried is 5 tons, Would it be safe to carry the load? What factors might play a role in setting 20% as the safety factor?

#Write a function called clean_data. clean_data takes one
#parameter, a dictionary. The dictionary represents the
#observed rainfall in inches on a particular calendar day
#at a particular location. However, the data has some
#errors.
#
#clean_data should delete any key-value pair where the value
#has any of the following issues:
#
# - the type is not an integer or a float. Even if the value
# is a string that could be converted to an integer (e.g.
# "5") it should be deleted.
# - the value is less than 0: it's impossible to have a
# negative rainfall number, so this must be bad data.
# - the value is greater than 100: the world record for
# rainfall in a day was 71.8 inches
#
#Return the dictionary when you're done making your changes.
#
#Remember, the keyword del deletes items from lists
#and dictionaries. For example, to remove the key "key!" from
#the dictionary my_dict, you would write: del my_dict["key!"]
#Or, if the key was the variable my_key, you would write:
#del my_dict[my_key]
#
#Hint: If you try to delete items from the dictionary while
#looping through the dictionary, you'll run into problems!
#We should never change the number if items in a list or
#dictionary while looping through those items. Think about
#what you could do to keep track of which keys should be
#deleted so you can delete them after the loop is done.
#
#Hint 2: To check if a variable is an integer, use
#type(the_variable) == int. To check if a variable is a float,
#use type(the_variable) == float.


#Write your function here!

#Below are some lines of code that will test your function.
#You can change the value of the variable(s) to test your
#function with different inputs.
#
#If your function works correctly, this will originally
#print (although the order of the keys may vary):
#{"20190101": 5, "20190103": 7.5, "20190104": 0, "20190107": 1}
rainfall = {"20190101": 5, "20190102": "6", "20190103": 7.5,
"20190104": 0, "20190105": -7, "20190106": 102,
"20190107": 1}

A company uses codes to represent its products, for example ABC2475A5R-14. Valid codes must have:

  • At least 10 characters (some codes have more than 10 characters)

  • Positions 4 through 7 must be digits (and represents the country in which the product will be sold)

  • The character in the 10th position must be a capital letter and represents the security level of the product.

Write a Python program that will read 10 product codes from a text file (Codes.txt - attached below). Determine if each conforms to the rules listed above:

If it does conform, print a heading: Valid Code(s) are: and list the codes that are valid. If it does not conform, print a heading: Invalid Code(s) are: and list the codes that area invalid. Be sure to test all possible combinations.

Further, if the code is valid, due to new government security laws, products with a security level of R (restricted) are no longer to be sold in countries with a country code of 2000 or higher. Output a heading: Invalid Restricted Code(s) are: and list the codes that are invalid in case you encounter any products that violate these new laws.

Imagine you are starting the firm with your Team and you are all college seniors with limited work experience (as probably some of you are!). You may not have impressive credentials to include in the management team section of your business plan.

  1. How can you construct this section of your plan, and the company itself, in a way that reassures the readers of the plan that you know what you’re doing and will get the advice you need to launch a successful company.
  2. Please discuss with your Team your answer and agree on what to do for your final plan.
    • Please summarize your discussion and final recommendation.
