In the grid below, points A and B have been rotated 90° counterclockwise around the origin. Give their image coordinates.

Step-by-step explanation:

4). Rule for the rotation by 90° counterclockwise about the origin is,

   (x, y) → (-y, x)

   For the given coordinates,

  A(1, 3) → A'(-3, 1)

  B(5, 6) → B'(-6, 5)

5). Rule used in question (4) is,

  (x, y) → (-y, x)

  Option (4) will be the correct option.

6). Coordinates of point C(2, 8) by rotation of 90° counterclockwise about the origin will be,

   C(2, 8) → C'(-8, 2)

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
