You are a Data Scientist at Anthem Blue Cross Blue Shield. You want to check if a patient will develop diabetes. Please write the R code to split the dataframe into test and training data. The proportion of split is 85/15, and the sample stratification needs to be done on the variable - age.

You work for a small company that exports artisan chocolate. Although you measure your products in kilograms, you often get orders in both pounds and ounces. You have decided that rather than have to look up conversions all the time, you could use Python code to take inputs to make conversions between the different units of measurement.
You will write three blocks of code. The first will convert kilograms to pounds and ounces. The second will convert pounds to kilograms and ounces. The third will convert ounces to kilograms and pounds.
The conversions are as follows:
1 kilogram = 35.274 ounces
1 kilogram = 2.20462 pounds
1 pound = 0.453592 kilograms
1 pound = 16 ounces
1 ounce = 0.0283 kilograms
1 ounce = 0.0625 pounds
For the purposes of this activity the template for a function has been provided. You have not yet covered functions in the course, but they are a way of reusing code. Like a Python script, a function can have zero or more parameters. In the code window you will see three functions defined as def convert_kg(value):, def convert_pounds(value):, and def convert_ounces(value):. Each function will have a block showing you where to place your code.

Suppose Alice downloads a buggy browser that implements TLS incorrectly. The TLS specification says that, during the handshake, the browser should send a random 256-bit number RB. Instead of picking RB randomly the browser always sends all zeros. Describe an attack that is possible against this buggy browser and how to update the browser so that this attack is no longer feasible.

# change amount as an integer input, and output the change using the fewest coins, one coin type per line. The coin types are Dollars, Quarters, Dimes, Nickels, and Pennies. Use singular and plural coin names as appropriate, like 1 Penny vs. 2 Pennies
my code produces no output and i cant find why?


coin_change =int(input())

def coin_change(cents):
if cents <= 0:
print( 'Zero cents.')
else:
quarter = cents // 25
dime = (cents % 25) //10
nickle = cents % 25 % 10 // 5
penny = cents % 5



print (coin_change )
# produces no output

In a multimedia presentation, when might voice-over be a better choice than placing the text on the screen?
when you have very little to say
when your audience is bored
when you have a lot to say
when you don’t want to write

In order to implement the classic DoS flood attack, the attacker must generate a sufficiently large volume of packets to exceed the capacity of the link to the target organization. Consider an attack using ICMP echo request (ping) packets that are 500 bytes in size (ignoring framing overhead). How many of these packets per second must the attacker send to flood a target organization using a 0.5-Mbps link
