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

while year<1:

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

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

while month<0:

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

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))

What is the value of the average variable after the following code is executed? var sum = 0; var prices = [14, 10, 9, 12, 11, 14

Reika [66]

Answer:

The value of average is 11

Explanation:

Analyzing the program line by line

This line initializes sum to 0

var sum = 0;

This line defines an array named prices and it also fills it with integer values.

var prices = [14, 10, 9, 12, 11, 14, 10, 8];

The italicized lines is an iteration that adds every element of prices and saves the result in variable sum

for( var i = 0; i < prices.length; i++ ) {

sum = sum + prices[i];

}

At this point, the value of sum is 88

The next line divides the value of sum (88) by the length of the array (8) which gives 11.

11 is then saved in variable average

var average = sum/prices.length;

Write a program in python that can compare the unit (perlb) cost of sugar sold in packages with different weights and prices. Th

Dmitrij [34]

Answer:

weight1 = float(input("Enter the weight of first package: "))

price1 = float(input("Enter the price of first package: "))

weight2 = float(input("Enter the weight of second package: "))

price2 = float(input("Enter the price of second package: "))

if weight1 > 0 and price1 > 0 and weight2 > 0 and price2 > 0:

unit_cost1 = price1 / weight1

unit_cost2 = price2 / weight2

if unit_cost1 < unit_cost2:

print("Package 1 has a better price.")

else:

print("Package 2 has a better price.")

else:

print("All the entered values must be positive!")

Explanation:

*The code is in Python.

Ask the user to enter the weight and the price of the packages

Check if the all the values are greater than 0. If they are, calculate the unit price of the packages, divide the prices by weights. Then, compare the unit prices. The package with a smaller unit price has a better price.

If all the entered values are not greater than 0, print a warning message

The more _____ a thumb drive has, the more storage capability it will provide. Hertz, bytes or pixels. The more _____ a micropro

beks73 [17]

Answer:

a) bytes

b) hertz

c) 1) hertz and 2) bytes

Explanation:

A byte is the basic unit of information and data stored in a computer storage. Hence, the storage capability of a drive will be measured in Bytes. On the other hand speed of processor is measured in terms of number of cycles made per second i.e hertz. Hence, the higher the value of hertz the higher is the speed of the computer.
