Write a function named "list_concat" that takes a list of strings as a parameter and returns the concatenation of all the values

Marina CMI [18]

Answer:

Following are the program in python language:

def list_concat(ls): #define function

if(len(ls) == 0): #set if condition

return ""

res = ""

for x in ls: #set for loop

res += x + " "

return res[:len(res)-1] #removing the extra spaces from list

ls = ['limit','break','ready'] #initialize the value in list

print(list_concat(ls)) #call the function

Output:

limit break ready

Explanation:

Here we declared a function "list_concat()" in which we pass an argument "ls" then check if condition that check the length of list .We also Iterating the loop in that function res[:len(res)-1] statement removes the extra space from the list and finally print the list

Catherine wants to search online for fruit juices. She is fine with aerated or fresh fruit juices. Which Boolean operator will e

ZanzabumX [31]

<h2>Answer:</h2>

<u>She will use the </u><u>OR Boolean operator</u>

<h2>Explanation:</h2>

Boolean Operators are used to connect and define the relationship between your search terms. Doing searching in any electronic databases like Google search engine, we use Boolean operators to either narrow or broaden our searches. The three Boolean operators are AND, OR and NOT. Among these operators OR is used to add the items. Since Catherine is searching for aerated or fresh fruit juices so she needs both the results therefore she must use OR operator.

Which of the following commands uses correct syntax for matching the patterns bunk or bank at the end of a line of text?

Alika [10]

Answer:

a. grep 'b[au]nk$' myLine

Explanation:

grep is a command used for searching a specified pattern in a given text.

Our goal is to match the character sequence - bank or bunk at the end of line in a given line referenced by myLine.

The regular expression for the specified match criterion is:

b[au]nk$

The second character can be either a or u.

$ indicates match at end of line.

So the overall grep command is :

grep 'b[au]nk$' myLine

A student who used a regression model that included indicator variables was upset when receiving only the following output on th

jeka57 [31]

Answer:

This is a multicolinearity problem and the student should determine the variable(s) that cause(s) the problem and remove it.

Explanation:

This information means that there exists a linear combination between the independent variables. The problem might have developed due to multicolinearity producing almost perfectly linearly dependent columns.

This could also be as a results of single matrix created when the student use an incorrect indicator variables and included an additional indicator column which created linearly dependent columns.

Acceleration is the rate at which an object changes its velocity. It is typically represented by symbol a and measured in m/s2 (

Natalija [7]

Answer:

<u>Pseudocode:</u>

INPUT velocity

INPUT time

SET velocity = 0.44704 * velocity

SET acceleration = velocity / time

SET acceleration = round(acceleration, 1)

PRINT acceleration

velocity = float(input("Enter a velocity in miles per hour: "))

time = float(input("Enter a time in seconds: "))

velocity = 0.44704 * velocity

acceleration = velocity / time

acceleration = round(acceleration, 1)

print("The acceleration is {:.2f}".format(acceleration))

Explanation:

*The code is in Python.

Ask the user to enter the velocity and time

Convert the miles per hour to meters per second

Calculate the acceleration using the formula

Round the acceleration to one decimal using round() method

Print the acceleration with two decimal digits
