Answer: 1/3
Step-by-step explanation:
We know that after dilation with scale factor k the coordinates of pre-image (x,y) map to (kx,ky) of the image.
From the given graph, the coordinate of A =(9,4) and the coordinate of A' (3,2)
Then
and 

Therefore, the scale factor of the dilation is 1/3.
Answer:
0.8
Step-by-step explanation:
The annual factor will be found by dividing any year's population by the population of the year before. The points most easily read from the graph are the populations for years 0 and 1. Then the annual factor is ...
factor = (year 1 population)/(year 0 population) = 320/400
factor = 0.8
Spinning on Y out of three letters (G, I and Y) = 1/3
then either an easy or hard = 1/2
so
The probability that the spinner will stop on the letter Y and then easy
= 1/3 x 1/2
= 1/6
= 0.17
answer:
0.17
