In the list of numbers, 6, x, 10, 2, 7, 13, and 15, the median is 10.
Which of the following could NOT be the value of x?
(A) 9
(B) 10
(C) 11
(D) 13

Step-by-step explanation:

Let’s put the number of the set 6, 10, 2, 7, 13, 15 in order from least to greatest :

2 , 6 , 7 , 10 , 13 , 15

we know that the median is the central value of the number set

then

if the median is 10

then x should be placed between 10 and 13 or 13 and 15

which means

x ≥ 10

therefore

9 could NOT be the value of x

step-by-step explanation: ; )

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
