Consider Statement 1: All prime numbers greater than 3 are equal to a multiple of six, plus 1 or minus 1. Let P(x) be the statem

ent "x is a prime number." Let Q(x) be the statement "x is greater than 3." Let R(x) be the statement "x % 6 = 1 or x % 6 = 5." (i.e. x is a multiple of 6, plus or minus 1)
Let U be the domain of x. (% represents the modulo operation in this question.)

a. Given the following definitions of U, translate the above statement into an expression of predicate logic.

i. U = all prime numbers greater than 3.

ii. U = all prime numbers.

iii. U = all positive integers.

Answer:

Explanation: P(x): Prime number; Q(x): Prime number greater than 3; R(x): Positive integer and U(x): All prime numbers

i) {∀x) (Q(x) ⇒  (U(x)}

ii) {∀x) (P(x) ⇒ (U(x)}

iii) {∀x) (R(x) ⇒(U(x)}

Answer:

The type of b is bool ( B )

The type of c is int ( C )

The type of d is int ( D )

Explanation:

The options that must hold zero are: The type of b is bool,The type of d is int and The type of c is int.

If b is true then c or d is true because c and d are int. this is because b been a true/false means that d and c are boolean int. because d and c are assigned to integers

mojhsa [17]

<em>Answer:</em>

<em>When listing to studying music or calm music it will help you considerate on a test or any home work that you are doing </em>

<em>Explanation:</em>

<em>Since 2006, two UCF professors neuroscientist Kiminobu Sugaya and world-renowned violinist Ayako Yonetani have been teaching one of the most popular courses in The Burnett Honors College. “Music and the Brain” explores how music impacts brain function and human behavior, including by reducing stress, pain and symptoms of depression as well as improving cognitive and motor skills, spatial-temporal learning and neurogenesis, which is the brain’s ability to produce neurons. Sugaya and Yonetani teach how people with neurodegenerative diseases such as Alzheimer’s and Parkinson’s also respond positively to music. </em>

<em> </em>

<em>“Usually in the late stages, Alzheimer’s patients are unresponsive,” Sugaya says. “But once you put in the headphones that play [their favorite] music, their eyes light up. They start moving and sometimes singing. The effect lasts maybe 10 minutes or so even after you turn off the music.” </em>

<em> </em>

<em>This can be seen on an MRI, where “lots of different parts of the brain light up,” he says. We sat down with the professors, who are also husband and wife, and asked them to explain which parts of the brain are activated by music.</em>

Write a program that uses nested loops to collect data and calculate the average rainfall over a period of years. The program sh
babunello [35]

Answer:

In Python:

year = int(input("Years: "))

while year<1:

   year = int(input("Invalid. Enter 1 or greater: "))

total = 0

for i in range(1,year+1):

   for j in range(1,13):

       month = int(input("Year "+str(i)+", Month "+str(j)+": "))

       while month<0:

           month = int(input("Invalid. Enter 0 or greater: "))

       total+=month

ave = total/(12*year)

print("Months: "+str(12 * year))

print("Total: "+str(total))

print("Average: "+str(ave))

Explanation:

This gets the number of years

year = int(input("Years: "))

This loop validates the number of years

<em>while year<1:</em>

<em>    year = int(input("Invalid. Enter 1 or greater: "))</em>

<em />

This initializes total to 0

total = 0

This iterates through the years

for i in range(1,year+1):

This iterates through the month of each year

   for j in range(1,13):

This gets the rainfall for each month

       month = int(input("Year "+str(i)+", Month "+str(j)+": "))

This loop validates the amount of rainfall

<em>        while month<0:</em>

<em>            month = int(input("Invalid. Enter 0 or greater: "))</em>

This calculates the total rainfall

       total+=month

This calculates the average rainfall

ave = total/(12*year)

This prints the number of month

print("Months: "+str(12 * year))

This prints the calculated total amount of rainfall

print("Total: "+str(total))

This prints the calculated average amount of rainfall

print("Average: "+str(ave))

In what cases would you denormalize tables in your database?
ad-work [718]

Answer: Denormalize is the mechanism is carried out by addition of the redundant bits in the already normalized database.The data is attached in the form of attributes,adding new tables.

This technique is used in the case of previously normalized data collection which requires improvement in the performance by reducing the errors.The improvement is made by making database readable ,adding  group of data in redundant form etc.

When data is to be retrieved quickly then also denormalization is used as by grouping or collecting information into a single table.
