In forming a chelate with a metal ion, a mixture of free EDTA (abbreviated Y4−) and metal chelate (abbreviated MYn−4) can buffer the free metal ion concentration at values near the dissociation constant of the metal chelate, just as a weak acid and a salt can buffer the hydrogen ion concentration at values near the acid dissociation constant.

The equilibrium

Mn++Y4−−⇀↽−MYn−4

is governed by the equation

K′f=αY4−*Kf=[MYn−4]/[Mn+][EDTA]

here Kf is the association constant of the metal and Y4−, αY4− is the fraction of EDTA in the form Y4−, and [EDTA] is the total concentration of free (unbound) EDTA. K′f is the conditional formation constant.

How many grams of Na2EDTA⋅2H2O (FM 372.23 g/mol) should be added to 1.55 g of Sr(NO3)2⋅4H2O (FM 283.69 g/mol) in a 500. mL volumetric flask to give a buffer with pSr2+=8.00 at pH 10.00? logKf for Sr−EDTA is 8.72 and αY4− at pH 10.00 is 0.30.

The epidemiology lab at the UVA Hospital is trying to estimate how COVID-19 is affecting African American communities living near the Hospital. They know that the infection rates of African Americans in the Baltimore area have been high, at 12% since March 2020. A small team of courageous researchers samples 12 people on the street in several areas near the Hospital – to ensure that they don’t know each other.

a. Please write out the values of the random variable X (the number of people who could be infected in the sample) and its probability distribution. Also draw a histogram of this probability distribution. Then, compute the mean using both the definitional formula and the special formula for this probability distribution.

b. What is the standard deviation of this sample? Compute this standard deviation using both the definitional formula and the special formula for this probability distribution.

c. What is the probability that exactly one-third of this sample is infected with COVID-19?

d. What is the probability that less than 3 students in this sample are infected with the virus?

e. If a much larger group of 110

Which of the following attacks can be mitigated by proper data retention policies?
A.   Dumpster diving
B.   Man-in-the-browser
C.   Spear phishing
D.   Watering hole

A security administrator needs to conduct a full inventory of all encryption protocols and cipher suites. Which of the following tools will the security administrator use to conduct this inventory MOST efficiently?

A security analyst is interested in setting up an IDS to monitor the company network. The analyst has been told there can be no network downtime to implement the solution, but the IDS must capture all of the network traffic. Which of the following should be used for the IDS implementation?

C.   Aggregation
D.   Port mirror

Which of the following is a security consideration for IoT devices?
A.   IoT devices have built-in accounts that users rarely access.

To obviate current beach erosion potentials and as a part of beach re-nourishment, Research department’s Dr. Smith proposed a construction of a series of submerged wave energy dissipation structures (=submerged-plate breakwaters) at 110 ft from the shoreline of the Beach. Based on design specifications of the structure, the distribution of the number of waves dissipatable by the proposed structure per hour could be approximated by a normal distribution with a mean of 189 waves and a standard deviation of 7 waves.
1) Use the Empirical Rule to describe the 90% distribution/range of X, i.e., the number
of waves dissipatable by the proposed structure per hour.
2) If the structure is built with dissipating a maximum 195 waves/hour capacity, what
fraction of an hour, i.e., minutes, might the structure be unable to handle incoming
waves (or in other word, how many minutes per hour the structure exceeds 195
waves/hour capacity)?
3) What wave dissipating capacity of the structure should be built so that the
probability of the incoming waves exceeding the structure capacity is equal to only
0.05 (or 5%)?

Write a python program using the following requirements:

Create a class called Sentence which

• has a constructor that takes a sentence string as input.
  • The default value for the constructor should be an empty string
  • The sentence must be a private attribute in the class
• contains the following class methods:
  • get_all_words — Returns all the words in the sentence as a list
  • get_word — Returns only the word at a particular index in the sentence
    • Arguments: index
  • set_word — Changes the word at a given index in sentence to a new word
    • Arguments: index, new_word
    • Does not return anything
  • a str method — Returns the sentence as a string using the built in method

Include a unit test in an if __name__ block to test the class. Use assert to check for errors.

Unit Test Example:

• Set a sentence variable with a sentence of your choice
• Instantiate the Sentence object using the variable
• Test that get_all_words() correctly returns that sentence as a list
• Test that get_word(#) correctly returns the # word in the sentence
• Test that replace() actually changes a word in the sentence object
• Print the sentence before and after the word change using the built in str method
