According to a survey of hikers on a trail, 50% of the hikers like Gatorade (G) and 40% like energy bars (E). 20% like both. Assume random selection:____________ a. Find the probability that a hiker likes Gatorade or energy bars b. If a hiker likes Gatorade, find the probability that he likes energy bars c. If a hiker likes energy bars, find the probability that he likes Gatorade.

Answers

Answer 1

Answer:

Explanation:

As per given data

Probability hikers like Gatorade (G) = P(G) = 50% = 0.5

Probability hikers like energy bars = P(E) = 40% = 0.4

Probability hikers like both = P(G and E) = 20% = 0.2

a)

To find the probability that a hiker likes Gatorade or energy bars use the following formula

P(G or E) = P(G) + P(E) - P(G and E )

P(G or E) = 0.5 + 0.4 - 0.2

P(G or E) = 0.7

b)

To find the probability that a hiker likes Gatorade or energy bars use the following formula

P(E|G) = P(E and G)/P(G)

P(E|G) = 0.2/0.5

P(E|G) = 0.4

c)

The probability that he likes Gatorade.

P(G|E) = P(G and E) / P(E)

P(G|E) = 0.2 / 0.4

P(G|E) = 0.5

(Python)Write an expression using Boolean operators that prints "Eligible" if user_age is greater than 17 and not equal to 25.


Sample output with input: 17

Ineligible

Answers

user_age = input("Input Age: ")

if int(user_age) <= 17:

   print("Ineligible")

elif int(user_age) == 25:

   print("Ineligible")

else:

   print("Eligible")

:Here is some basic code.  It takes an input, turns it into an int type value, and checks the parameters that you gave me.  It errors out when you put in anything but a number.

Answer:

user_age = int(input())

if (user_age > 17) and (user_age != 25):

   print('Eligible')

else:

   print('Ineligible')

Explanation:

the code is very easy to do because it asks for it in Boolean operators.  So user_age = int(input()) ## asks for user input

then it checks the status by seeing if the number is greater than 17 and not equal to 25.  we know that > is greater and we know that != means not equal.  Therefore, this will rule out both and then give the eligible or ineligible statement.

Answers

Answer:

On cell R8, type in the formula  "=AVERAGEIF(M2:M31,"Elected",D2:D31)".

Explanation:

Microsoft Excel is a spreadsheet application developed by Microsoft as a part of the office package, used for statistical analysis of data. It has several tools used for this purpose.

The AVERAGEIF function is used to give the average of numeric column based on a condition. The formula above uses the word 'Elected' in the M column to calculate the average of numbers in the D column.

The formula to enter in cell R8 is =AVERAGEIF(M2:M31,"Elected",D2:D31)

The AVERAGEIF function is used to calculate the average of a range of numbers if a certain condition is true.

From the complete question,

The range is M2 to M31

The condition is to check is the students in range D2 to D31 have been elected

The syntax of the AVERAGEIF function

=AVERAGEIF(range,criteria,average_range)

So, the formula to enter in cell R8 is =AVERAGEIF(M2:M31,"Elected",D2:D31)

g P4. (5pts) IPv4 tunneling was introduced to solve this issue of forwarding IPv6 packets via IPv4 routers. Please explain how this mechanism works.

Answers

Answer:

In IPv4 tunneling, IPv6 packets are encapsulated in the IPv4 packets, adding a header comparing the source IP, the packet entry point to the tunnel and the destination point, as well as the exit point of the tunnel.

Explanation:

IPv6 is the latest version of the network address. They eliminate the exhaustion of addresses experienced in IPv4, but is it not used in all networks which makes it hard to communicate with other networks with IPv4 and with IPv6 addresses through IPv4 medium.

To avoid the needed to reconfigure other IPv4 networks to IPv6 and establish communication between the networks, IPv4 tunneling is used to transmit IPv6 packets from one IPv6 network to other IPv6 networks through the IPv4 transmission cables or mediums.

How does SQL allow implementation of the entity integrity and referential integrity constraints?

Answers

Explanation:

Entity Integrity

The Entity Integrity helps to ensure each row in a table to be a uniquely identifiable entity. For example, product ID column  of products table is a primary key for the table.

Entity integrity ensures any two properties for the primary keys. The primary key for a row is unique. The primary key is not null, no component of the primary key my be set tonal. This property is unique and the second property ensures that primary key has a meaning has a value.

Referential integrity

The Referential integrity make sure that the relationship between tables remains or data is inserted, deleted or even modified. It specifies that the value that appears in a certain relation for a given set of some attributes, it also appears for the certain set of attributes in some other relation.

Referential triggered actions:

The Referential integrity actions are mostly triggered by physical and not by logical, or updates to unique value.
