Answer:

First blank: MAX

Second blank: AVERAGE

Explanation:

Required

Complete the blanks

The first blank is to be filled with a function that calculates the highest score from a given range of scores (cells).

To do this, we make use of the MAX function, and the syntax is:

=MAX(cell_range)

The second blank is to be filled with a function that calculates the mean score from a given range of scores (cells).

To do this, we make use of the AVERAGE function, and the syntax is:

=AVERAGE(cell_range)

Paladinen [302]

Answer:

Option B; 30 SECONDS OR LESS.

Explanation:

Short-term memory, also known as primary or active memory, is the information we are currently aware of or thinking about.

When short-term memories are not rehearsed or actively maintained, they last mere seconds.

Most of the information kept in short-term memory will be stored for less than 30 seconds (approximately 20 to 30 seconds), but it can be just seconds if rehearsal or active maintenance of the information is not done.

Therefore, Anita likely will be able to retain the information in short-term memory, without additional processing, for 30 SECONDS OR LESS.

Just five types of pointing device,list

posledela

Answer:

five types of pointing devices

Explanation:

Ponting devices

Pointing means point something and the pointing devices are the input /peripheral devices those are used to point the pointer on the screen. We do move cursor on the screen to open the files or any icon.

There are many types of pointing devices but these are quite common which are given below

Computer mouse
Finger on touch screen.
Joystick.
Leap Motion.
Light pen (pen)

1.Mouse

Mouse is most common type of input device that is used for pointing the data on the screen. We press it with our hands and keep pointing the things.

There are three types of mouse

optical mouse
wireless mouse
trackball mouse.

2. Finger on touch screen

In this type of movement the fingers are input devices those we use to see the movement of pointer on the screen and this is most common in this century.

3.Joystick.

Joystick is another input device to point the cursor but it is mostly used in games. Children can use it smartly so it is inculcated in games usually.

4. Leap Motion

The Leap Motion (LM) controller is a latest 3D sensing device for hand posture interaction with a computer. It is having the capability sense the location of the fingers of the hands, as well as the palm position.

5.Light Pen

this is another pointing device which is mostly used to highlight and select the data on the screen.

Note: All of these above pointing devices are most common used now a days. These devices are having new conventions day by day for the ease of user. This era is basically the era of IT ,so the use of computer must be so easy and conventional for the user so, the innovations and improvement in such devices is made side by side.

I don’t understand how to make a hyperlink or put an image in an html file

Mademuasel [1]

To use image as a link in HTML, use the <img> tag as well as the <a> tag with the href attribute. The <img> tag is for using an image in a web page and the <a> tag is for adding a link. Under the image tag src attribute, add the URL of the image. With that, also add the height and width.

Don wishes to swap the values of the variables x and y in his program. He adds a line of code which sets the value of x to the v

12345 [234]

Answer:

The correct answer is (c): The value of both x and y will be set to the original value of y.

Explanation:

Let suppose, we assign some value to variable x and to variable y i.e.

var x=10

vary y=15

Then Don adds a line of code which set the value of x to value of y i.e.

x=y

here it is mean that value of x become 15.

So after this line the value of x is 15 and y is also 15

Then he also added a line of code which set the value of y to value of x. i.e.

y=x

By adding this line of code, the value of y is 15 because x is equal to 15.

Therefore, the value of both x and y will be set to the original value of y.

Why other option are not correct

a. After swapping the value of both variable it is impossible that both variable retain original value in it.

b. this option is only true if in this first line he set the value of y to value of x and in the second line set the value of x to value of y.

d. When you swap two values, there is need of third variable for swapping, when you will swap the value only between two variable, only one variable value will be retained and intended swapping will not be performed
