Let x = 11

12∣∣−11+3∣∣−5

Do the absolute value first

12∣∣-8∣∣−5

Taking the absolute value, which means making it positive

12* 8 -5

Rotate the rectangle 90° clockwise about the origin.

WINSTONCH [101]

The coordinates of the new rectangle formed after transformation are; A'(3, -1); B'(6, -1); C'(6, 4); D'(3, 4)

<h3>How to carry out rotational transformation?</h3>

We are told that the original rectangle which I labelled ABCD in the attached image is rotated 90° clockwise about the origin.

Now, from the translation of Rectangle ABCD into A'B'C'D' using the transformation rule in the question, the new coordinates are;

A'(3, -1)

B'(6, -1)

C'(6, 4)

D'(3, 4)

A thief steals an atm card and must randomly guess the correct three digit pin code from a 9 key keypad repetition of digits is

marissa [1.9K]

Answer:

1/729

Step-by-step explanation:

Assuming that the probabilities of each digit in the pin is independent from the other digits, the answer to this question can be calculated. There are total of 9 digits, out of which 1 digit is correct. This is true for all the three digits. So the probability of choosing the correct digit in the first place in the first try will be 1/9. Since this is true for the rest of the digits as well and they are independent, we can safely multiply the probabilities. So P(Correct Guess in the first try) = 1/9 (first place) * 1/9 (second place) * 1/9 (third place) = $1/9^3$ = 1/729. So the correct answer is 1/729!!!
