Ryan wants to describe the translation shown on the grid below. ryan uses the following steps to describe the translation. step 1: identify the pre-image and the image: the pre-image is triangle xyz, and the image is x'y'z'. step 2: identify the number of units that each point moves horizontally: each point moves one unit left. step 3: identify the number of units that each point moves vertically: each point moves three units down. step 4: the translation is one unit left and three units down. in which step did ryan make the first error? a. step 1 b. step 2 c. step 3 d. step 4

Option C. Step 3

Step-by-step explanation:

step 1

Identify the pre-image and the image: The pre-image is triangle XYZ, and the image is X'Y'Z'

The step 1 is correct

step 2

Identify the number of units that each point moves horizontally: Each point moves one unit left.

The step 2 is correct

step 3

Identify the number of units that each point moves vertically: Each point moves three units down

The step 3 is not correct

Each point moves three units up

step 4

The translation is one unit left and three units down

the step 4 is not correct

The translation is one unit left and three units up

therefore

The first error is in the Step 3

All is correct up to Step 3, where the direction should be described as Up instead of Down. C is the best choice.

if this is really you s much. i only have 3 points left and i have 2 questions to ask

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
