Triangle J′K′L′ shown on the grid below is a dilation of triangle JKL using the origin as the center of dilation: Two triangles are drawn on a grid. First triangle has vertices J 8 and 12, K 4 and 8, L 12 and 6. Image triangle has vertices J prime 4 and 6, K prime 2 and 4, L prime 6 and 3.

Which scale factor was used to create triangle J′K′L′?

4
one quarter
2
one half

one half

Step-by-step explanation:

The vertices of triangle J′K′L′ are all half of their counterparts in Triangle J′K′L′ which means that the scale factor used was one-half.

First triangle has vertices J 8 and 12.

= 8/2 = 4

= 12/2 = 6

Image triangle has vertices J prime 4 and 6.

First triangle has vertices K 4 and 8

= 4/2 = 2

= 8 / 2 = 4

Image triangle has vertices K prime 2 and 4.

First triangle has vertices L 12 and 6

= 12/2 = 6

= 6/2 = 3

Image triangle has vertices L prime 6 and 3.

It is 1/4 I believe.

Step-by-step explanation:

binomial distribution

median= 2

range = 7-0 = 7

how to find median?

no. of term=28

median=(28+1)/2=14.5th term

the 14th and 15th term are 2, therefore the median is (2+2)/2 = 2

450 is the final answer! : )
