PLEASE HELP URGENTT Lamar goes shopping for a new flat-panel television. A television is usually described by the length of the
screen’s diagonal. He finds a great deal on a 42-inch display model.
a. If the screen’s height is 21 inches, what is the width of the screen?
b. The border around the screen is 2 inches. What are the dimensions of the television, including
the border?

Step-by-step explanation:

d^2=h^2+w^2

a)

w^2=42^2-h^2, h=21

w^2=1764-441

w^2=1323

w=36.373

b)

36.373+2(2) by 21+2(2)

w=40.373, h=25

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
