Answer:

You can use the rename function to change the column name. Here is an example code chunk:

flavors_df %>%

rename(Company = Company...Maker.if.known.)

This will rename the Company...Maker.if.known. column to Company. Note that the old column name is surrounded by backticks () because it contains a period, which is a special character in R. The new column name, Company`, does not need to be surrounded by backticks because it does not contain any special characters.

Answer:

c. let v = silo.volume();

Explanation:

When you create and initialize a new object you pass through that object's class constructor. The constructor is in charge of initializing all the necessary variables for that class including radius and height. Once you save the object in a specific variable (silo) you need to call the class methods through that variable, using the '.' command. Therefore, in this scenario, in order to call the volume() method you would need to call it from the silo object and save it to the v variable, using the following statement.

let v = silo.volume();

Punch card is the oldest computer storage; followed by tape and then floppy disk. Hard drive goes back as far as floppy but is still in use today. CD/DVD/BR discs are all later storage but are also used for storing music and videos. USB flash, SD card, SSD and cloud storage are the common technologies used today for data storage.

Answer:

Explanation:

the other answer talks about when the different storages were used; here are their capacity comparison; in increasing order:

punch card - one hole represents 1 bit

tape - slightly more w/ 0/1 represented by sound

floppy disk - more as 0/1 represented by magnetics

hard drive - also magnetics but capacity ranges from okay (in MB) at the beginning to enormous (in TB) currently

CD - beginning to be okay but still under 1 GB

DVD and BR - better 5-28GB

USB/SD/SSD - good; all in 10s to 100s of GB

cloud storage - UNLIMITED!

The function is as follows:

def compute_net_correlation(data_series_1,data_series_2):

   series1 = 0; series2 = 0

   for i in range(len(data_series_1)):

       series1+=data_series_1[i]

       series2+=data_series_2[i]

   avg_series1 =series1/len(data_series_1)

   avg_series2 =series2/len(data_series_1)

   for i in range(len(data_series_1)):

       data_series_1[i]-=avg_series1

       data_series_2[i]-=avg_series2

       data_series_1[i]*=data_series_2[i]

   net_correlation = 0

   for i in range(len(data_series_1)):

       net_correlation +=data_series_1[i]

   return net_correlation

Explanation:

This defines the function

def compute_net_correlation(data_series_1,data_series_2):

This initializes the sum of each series to 0

   series1 = 0; series2 = 0

This iterates through each data series

   for i in range(len(data_series_1)):

This adds series 1

       series1+=data_series_1[i]

This adds series s

       series2+=data_series_2[i]

This calculates the average of data series 1

   avg_series1 =series1/len(data_series_1)

This calculates the average of data series 2

   avg_series2 =series2/len(data_series_1)

This iterates through each data series

   for i in range(len(data_series_1)):

This subtracts the average from series 1

       data_series_1[i]-=avg_series1

This subtracts the average from series 2

       data_series_2[i]-=avg_series2

This multiplies the corresponding elements of both series

       data_series_1[i]*=data_series_2[i]

This initializes the net correlation to 0

   net_correlation = 0

This iterates through each data series

   for i in range(len(data_series_1)):

This adds up the corresponding elements of both series

       net_correlation +=data_series_1[i]

This returns the net correlation

   return net_correlation

Explanation:

One example of FLAT artwork is the Tagged Image File Format (TIFF). TIFF is a common computer file format used for storing raster images.

It is a flexible format that can support a wide range of color depths and image compression methods. It is often used for high-quality images, such as those used in printing, and is supported by a wide range of image-editing software.

Therefore, based on the context of the above, TIFF files are FLAT artwork as they are a single, static image without any animations or interactivity.

Answer:

The program in Python is as follows:

age = int(input("Age: "))

carryOn = int(input("Carry on Bags [0 or 1]: "))

checkedBags = int(input("Checked Bags [0 or greater]: "))

airFare = 300

if age >= 60:

   airFare = 290

elif age <= 2:

   airFare = 0

if carryOn ==  1:

   airFare += 10

if checkedBags ==  2:

   airFare += 25

elif checkedBags >  2:

   airFare += 25 + 50 * (checkedBags - 2)

print("Airfare: ",airFare)

Explanation:

This gets input for age

age = int(input("Age: "))

This gets input for carry on bags

carryOn = int(input("Carry on Bags [0 or 1]: "))

This gets input for checked bags

checkedBags = int(input("Checked Bags [0 or greater]: "))

This initializes the base cost to 300

airFare = 300

This updates the base cost to 290 for adults 60 years or older

if age >= 60:

   airFare = 290

This updates the base cost to 0 for children 2 years or younger

elif age <= 2:

   airFare = 0

This updates the airFare if carryOn bag is 1

if carryOn ==  1:

   airFare += 10

if carryOn bag is 0, the airFare remains unchanged

This updates the airFare if checkedBags is 2. The first bag is free; so, only the second is charged

if checkedBags ==  2:

   airFare += 25

This updates the airFare if checkedBags greater than 2. The first bag is free; so, only the second and other bags is charged

elif checkedBags >  2:

   airFare += 25 + 50 * (checkedBags - 2)

if checkedBags is 0 or 1, the airFare remains unchanged

This prints the calculated airFare

print("Airfare: ",airFare)

Hit rate = 80%

Miss rate = 20%

Hit time = 0.3 ns  

Miss penalty = 0.4 ns

AMAT ≈ 3.875 ns

Explanation:

8 out of 10 = 0.3ns. to return data  ( also finds data in the upper level )

2 out of 10 = 0.7 ns to return data

a) Hit rate in upper level memory

= 8/10 * 100 = 80%

b) Miss rate

= 2/ 10 * 100 = 20%

c) Hit time in the upper level memory

Hit time = 0.3 ns

d) Miss penalty

This is the time taken by the missed requests to return their own data

= 0.7 ns -  0.3 ns =  0.4 ns

e) AMAT ( average memory access time )

Hit rate = 80% , Hit time = 0.3ns

miss rate = 20%  Miss time = 0.7 ns

hence AMAT = (0.3 / 0.8 ) +  (0.7 / 0.2 )

                      ≈ 3.875 ns

Too much photoshop to the point where you start to resemble Kim Kardashian is way too much. Simple men like me enjoy average women. Like makeup, an absurd amount of photoshop will deter most men as they'll find you shallow and fraudulent. More women should start to flaunt their natural beauty.
