(80 POINTS) What rule describes a dilation with a scale factor of ½ and the center of dilation at the origin?
lesya [120]

Answer:

C

Step-by-step explanation:

(x, y) -> (1/2x, 1/2y)

When you dilate a side, point, etc, you are multiplying the original dimension by the scale factor. That is represented in option C: the original x and y are multiplied by the scale factor, 1/2! Hope that helps! :)

Olenka [21]

Answer:

mean=13.2

median=13

mode=14

Step-by-step explanation:

mean=sum of values/number of values

sum of values=9+17+14+12+14+14+9+11+10+20+10+22+11+11+9+15+14+15=237

number of values=18

mean=237/18=13.17

Mean=13.2

Arranging data in ascending order

9 9 9 10 10 11 11 11 12 14 14 14 14 15 15 17 20 22

n/2=18/2=9 is an integer so,

median= the average of (n/2)th and (n/2 +1)th observation

median=(12+14)/2=26/2=13

Median=13

Mode= The most repeated observation in the data

14 is repeated more than other numbers so, 14 is the mode for this data.

Mode=14
