D

8

Statistics JSA 2021
Correct Answer: C
Explanation

With 3 points we can describe a polynomial of degree 2 .

so our desired polynomial is of the form y=ax+ bx + c.

plugging the above given values in the above quadratic equation we get

5 = a x 0 + b x 0 + c 

=> c = 5.

6 = a x 1 x 1 + b x 1 +c

=> 6 = a+ b + c

but c = 5

so a + b = 1

also

8 = a x 2 x 2 + b x 2 +c

8 = 4a + 2b + 5

but a+b = 1 using this we get

b = 1/2 , a = 1/2, also c = 5

using these values we get value for P(3) as:

(1/2) x 3 x 3 + (1/2) x 3 +5 

9/2 + 3/2 +5 = 1

laser

Computer JSA 2021 VERIFIED
Correct Answer: D
Explanation

A laser printer uses a combination of the laser beam and electrophotographic techniques. Laser printing is an electrostatic digital printing process. It produces high-quality text and graphics by repeatedly passing a laser beam back and forth over a negatively charged cylinder called a "drum" to define a differentially charged image. The drum then selectively collects electrically charged powdered ink (toner), and transfers the image to paper, which is then heated in order to permanently fuse the text, imagery, or both. As with digital photocopiers, laser printers employ a xerographic printing process.
