The figure shows triangle pqr and some of its transformed images on a coordinate grid: a coordinate grid is shown from positive 6 to negative 6 on the x-axis and from positive 6 to negative 6 on the y-axis. a triangle labeled pqr is shown on ordered pair 1, 1 and 1, 4 and 3, 1. another triangle labeled image a is shown on ordered pair 1, negative 1 and 1, negative 4 and 3, negative 1. another triangle labeled image b is shown on ordered pair negative1, negative 1 and negative 1, negative 4 and negative 3, negative 1. another triangle labeled image c is shown on ordered pair negative 5, 1 and negative 5, 4 and negative 3, 1. another triangle labeled image d is shown on ordered pair negative1, 1 and negative 1, 4 and negative 3, 1. which of the four triangles was formed by a translation of triangle pqr? a b c d

C

Step-by-step explanation:

Triangle A is a reflection across the x-axis. All the y coordinates are negated.

Triangle B is a rotation 180° about the origin. All coordinates are negated.

Triangle C is a translation to the left by 6 units. 6 is subtracted from each x-coordinate.

Triangle D is a reflection across the y-axis. All the x-coordinates are negated.

Comment on presentation

Your question would be much easier to read if you would simply use minus signs (hyphens) and conventional ordered-pair presentation: (1, -1), (1, -4), (3, -1), for example, for triangle A.

B) At Maryland, the mean number of points per player per game is greater than the median number of points per player per game.

Step-by-step explanation:

Baylor University

There are 6 players who each score 12 points per game.

There are 6 players who each score 0 points per game.

The Points of the 12 players are: 0,0,0,0,0,0,6,6,6,6,6,6

University of Maryland

One player scores 58 points per game,

One player scores 14 points per game,

The rest(10) of the players score 0 points per game.

The Points of the 12 players are: 0,0,0,0,0,0,0,0,0,0,14,58

Dartmouth College

4 players score 5 points per game.

4 players score 6 points per game.

4 players score 7 points per game.

The Points of the 12 players are: 5,5,5,5,6,6,6,6,7,7,7,7

The following therefore applies:

B) At Maryland, the mean number of points per player per game is greater than the median number of points per player per game.
