In a spreadsheet what does the following symbol mean?
$
Answers
Answer:
$ = dollar sign
Explanation:
In a spreadsheet, the $ symbol is the symbol of the dollar. The dollar is the currency of the United States.
What is currency?Currency is a form of payment for goods and services. In a nutshell, it is money in the form of paper and coins that is usually issued by a government and is generally accepted as a form of payment at face value.
Currency exchange rates differ between businesses because each one distorts the interbank rate to maximize profits. We encounter numerous competitors who post interbank rates internet as bait to attract new customers, but once the customers are onboard, they drastically change the rate, typically not in the customers' favor.
Therefore, the $ symbol represents the dollar in a spreadsheet. The US dollar is the country's currency.

Answers
Answer:
I don't know how to code C++
Explanation:
In numerical methods, one source of error occurs when we use an approximation for a mathematical expression that would otherwise be too costly to compute in terms of run-time or memory resources. One routine example is the approximation of infinite series by a finite series that mostly captures the important behavior of the infinite series.
In this problem you will implement an approximation to the exp(x) as represented by the following infinite series,
exp(x) = Infinity n= 0 xn/xn!
Your approximation will be a truncated finite series with N + 1 terms,
exp(x, N) = Infinityn n = 0 xn/xn!
For the first part of this problem, you are given a random real number x and will investigate how well a finite series expansion for exp(x) approximates the infinite series.
Compute exp(x) using a finite series approximation with N E [0, 9] N (i.e. is an integer).
Save the 10 floating point values from your approximation in a numpy array named exp_approx. exp_approx should be of shape (10,) and should be ordered with increasing N (i.e. the first entry of exp_approx should correspond to exp(x, N) when N = 0 and the last entry when N = 9).
Answers
Answer:
The function in Python is as follows:
import math
import numpy as np
def exp(x):
mylist = []
for n in range(10):
num = (x**n)/(math.factorial(n))
mylist.append([num])
exp_approx = np.asarray(mylist)
sum = 0
for num in exp_approx:
sum+=num
return sum
Explanation:
The imports the python math module
import math
The imports the python numpy module
import numpy as np
The function begins here
def exp(x):
This creates an empty list
mylist = []
This iterates from 0 to 9
for n in range(10):
This calculates each term of the series
num = (x**n)/(math.factorial(n))
This appends the term to list, mylist
mylist.append([num])
This appends all elements of mylist to numpy array, exp_approx
exp_approx = np.asarray(mylist)
This initializes the sum of the series to 0
sum = 0
This iterates through exp_approx
for num in exp_approx:
This adds all terms of the series
sum+=num
This returns the calculated sum
return sum
Write an interface called Shape, inside, there is a method double area(); write a class called Box which implements the Shape. In Box, there are two data members: a double called length, and a double called width. Also implements constructor, and the method area() which calculates the area by multiplying the length and width. Then write a Tester class, which has a main method and creates a box object and displays the area.

Explanation:
The following code is written in Java. It contains the interface Shape, the class Box, and a tester class called Brainly with the main method. Box implements the Shape interface and contains, the instance variables, the constructor which takes in the inputs for length and width, getter methods for length and width, and the defines the area() method from the interface. Then the object is created within the Brainly tester class' main method and the area() method is called on that object. Output can be seen in the image attached below.

Write a test program that prompts the user to enter the number of the items and weight for each item and the weight capacity of the bag, and displays the maximum total weight of the items that can be placed in the bag. Here is a sample run:
Answers
Answer:
The program in Python is as follows:
n = int(input("Number of weights: "))
weights= []
for i in range(n):
inp = float(input("Weight: "))
weights.append(inp)
capacity = float(input("Capacity: "))
possible_weights = []
for i in range(n):
for j in range(i,n):
if capacity >= weights[i] + weights[j]:
possible_weights.append(weights[i] + weights[j])
print("Maximum capacity is: ",max(possible_weights))
Explanation:
This gets the number of weights from the user
n = int(input("Number of weights: "))
This initializes the weights (as a list)
weights= []
This iteration gets all weights from the user
for i in range(n):
inp = float(input("Weight: "))
weights.append(inp)
This gets the weight capacity
capacity = float(input("Capacity: "))
This initializes the possible weights capacity (as a list)
possible_weights = []
This iterates through the weights list
for i in range(n):
for j in range(i,n):
This gets all possible weights that can be carried by the bag
if capacity >= weights[i] + weights[j]:
possible_weights.append(weights[i] + weights[j])
This prints the maximum of all possible weights
print("Maximum capacity is: ",max(possible_weights))

why the internet is not considered a mass medium in Africa
Answers
“Mass media,” therefore, would be that content created by a few and copied to the many — a large circulation newspaper, for example, or a network television or radio program.
The internet’s content is anything but “mass” in that regard — there is mass media content on it, to be sure, but there is also a panoply of content created by many for dissemination to many — or the few who are attracted by the content created by a certain few, or a certain individual. The reasons why there is not an internet infrastructure like in other regions is because in Africa people have low levels of computer literacy, there is poor infrastructures in power supply and urbanism in general, and Internet services are offered only at a high cost. Hope this helps!
Answer:
the reason why internet not considered as a mass medium is probably because most of the African are not educated and civilized, thereby making them not common to the usage of the internet.

The project downloaded contains a package (folder) named Q1 within the src folder. Inside Q1 is a Java class named Questions. The purpose of Question 1 is to examine your understanding of loops and branching conditions. You should implement all of your code for this question in the main method of the Questioni class. While significant detail is provided below to be sure you undertand what is required, please note that the amount of code required to solve this question (Parts a-c) is less than 10 lines (total). In the Question1 class, you are given a line of code that generates a random number between 0 and 1. Math.random(): //generates number between 0 and 1 val
You are to create a loop which, in each iteration, generates a new random value, assigns it to val using the line provided and checks to see if that val is greater than 0.5. If val is greater than 0.5, a variable named counter should be incremented. The loop should continue this process (generate random value, check if it is greater than 0.5) until a total of three random numbers generated are greater than 0.5 (values do not have to be consecutive). You should also use the variable named numIterations, which is included for you, to track how many iterations of your loop were required for you to generate three random numbers greater than 0.5. A printin() statement is included for you that displays the value of numlterations. As an example of how the program should behave, if the following sequence of random numbers are randomly generated from your loop
0.3, 0.7,0.2, 0.6,0.9
then numIterations would equal 5 (the third value greater than 0.5 occured on the fifth iteration).
If
0.6, 0.8, 0.75
was the random sequence of numbers generated by your loop, then numlterations would equal 3 (the third value greater than 0.5 occured on the third iteration).
These are two examples to illustrate the scenario given in Question 1. Since at each iteration of your loop the number generated is random, the value of numIterations that your program observes may be any value greater than or equal to 3. Note that your program does not need to print out each of the random values that it generates. The steps to solve Question 2 are broken down as follows.
a. Implement a branching condition that increases the variable counter by 1 if val is larger than 0.5 1
b. Add a loop around the code created in Part a that continues until counter equals 3.
c. Use the variable numlterations to count how many times your loop iterates.
