Complete Question:

Which of the following statement is true?

Group of answer choices.

A. When declaring a variable, you also specify the type of its values.

B. Variables cannot be assigned and declared in the same statement.

C. Variable names can be no more than 8 characters long.

D. Variable names must contain at least one dollar sign.

Answer:

A. When declaring a variable, you also specify the type of its values.

Explanation:

In Computer programming, a variable can be defined as a placeholder or container for holding a piece of information that can be modified or edited.

Basically, variable stores information which is passed from the location of the method call directly to the method that is called by the program.

For example, they can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function. Therefore, when you create variables in a function, you can can set the values for their parameters.

For instance, to pass a class to a family of classes use the code;

\\parameter Name as Type (Keywords) = value;

\\procedure XorSwap (var a,b :integer) = "myvalue";

<em>Hence, the true and correct statement is that when declaring a variable, you also specify the type of its values such as integers, string, etc. </em>

Answer:

Explanation:

The question does not provide any actual data to manipulate or use as input/guidline therefore I have taken the liberty of creating a function for each of the question's points that does what is requested. Each of the functions takes in a list of the needed data such as a list of field test averages for part 1, or a list of field tests for part 2, etc. Finally, returning the requested output back to the user.

import matplotlib.pyplot as plt

from collections import Counter

def best_pilot(field_test_average):

return max(field_test_average)

def find_average(field_test):

average = sum(field_test) / len(field_test)

return average

def create_histogram(field_test_colors):

count_unique_elements = Counter(field_test_colors).keys()

plt.hist(field_test_colors, bins=len(count_unique_elements))

plt.show()

def average_name_lengths(first, last):

first_name_sum = 0

last_name_sum = 0

count = 0

for name in first:

first_name_sum += len(name)

count += 1

for name in last:

last_name_sum += len(name)

first_name_average = first_name_sum / count

last_name_average = last_name_sum / count

return first_name_average, last_name_average

3.14 LAB: Simple statistics for Python

Ad libitum [116K]

Answer:

Following are the correct python code to this question:

n1 = float(input('Input first number: '))#input first number

n2 = float(input('Input second number: '))#input second number

n3 = float(input('Input third number: '))#input third number

n4 = float(input('Input fourth number: '))#input fourth number

average = (n1+n2+n3+n4)/4 #calculate input number average

product = n1*n2*n3*n4 # calculate input number product

print('product: {:.0f} average: {:.0f}'.format(round(product),round(average))) #print product and average using round function

print('product: {:.3f} average: {:.3f}'.format(product,average)) #print product and average value

Output:

Please find the attachment.

Explanation:

The description of the above python code can be defined as follows:

In the above python program four variable "n1, n2, n3, and n4" is defined, in which we take input from the user end, and in these user inputs we use the float method, that converts all the input value in to float value.
In the next step, two variable average and product are defined, that calculate all input numbers product, average, and hold value in its variable.
In the last line, the print method is used, which prints its variable value by using a round and format method.
