8 0

Explanation:

Using this technique a number is represented in bits by three parts: sign, exponent, and fraction. This is similar to scientific notation used to represent large or small numbers (e.g. ). The sign is negative, the exponent is 8 and the fraction is 0.35.

What is the best use of a line chart?

lapo4ka [179]

Line graphs can also be used to compare changes over the same period of time for more than one group. Pie charts are best to use when you are trying to compare parts of a whole. They do not show changes over time. Bar graphs are used to compare things between different groups or to track changes over time.

What should you do if a headset plugged into your computer is not working properly?

Alex777 [14]

If a headset plugged into computer is not working properly than one can go for updating the device driver. The correct option is B.

<h3>What is a device driver?</h3>

A device driver is a type of software application that allows one hardware device (such as a computer) to communicate with another hardware device (such as a printer). A device driver is indeed referred to as a software driver.

A driver, also known as a device driver, is a collection of files that instructs a piece of hardware on how to operate by communicating with a computer's operating system.

Every piece of hardware, from internal computer components like your graphics card to external peripherals like a printer, requires a driver.

If a headset plugged into a computer is not working properly, the device driver can be updated.

Thus, the correct option is B.

a. Write a function called fizzbuzz. This function will take 1 number as a parameter. The function will print all numbers from 0

OLga [1]

Answer:

def fizzbuzz (num):

for item in range(num):

if item % 2 == 0 and item % 3 == 0:

print("fizzbuzz")

elif item % 3 == 0:

print("buzz")

elif item % 2 == 0:

print("fizz")

else:

print (item)

fizzbuzz(20)

Explanation:

Using Python programming Language

Use a for loop to iterate from 0 up to the number using the range function

Within the for loop use the modulo (%) operator to determine divisibility by 2 and 3 and print the required output

see attached program output screen.

If I gain a rank and go under the points that the rank coust do I lose the rank

padilas [110]

This is a good question, and I've wondered about that myself. I'm going to 'report' the question, not because there's anything wrong with it, but to bring it to the attention of the Moderators, so they can tell both of us.

mestny [16]

The conclusion sustains the thermogram will be that the windows are not energy efficient, but the roof stands energy efficient.

<h3>What is Thermography?</h3>

Thermography exists a noninvasive method that employs an infrared camera to develop pictures that depict patterns of heat and blood flow on or around the body's surface. A thermogram taken outside a house shows high quantities of thermal energy around the windows but not around the roof. The conclusion that supports the thermogram will be that the windows are not energy efficient, but the roof exists energy efficient.

Thermal energy (also named heat energy) is produced when a rise in temperature pushes atoms and molecules to move faster and collide with each other. The energy that reaches the temperature of the heated substance is named thermal energy. The term "thermal energy" exists utilized loosely in various contexts in physics and engineering. It can guide several different well-defined physical concepts.
