5.5

Step-by-step explanation:

because the middle most number is 5,6

so

5+6=11

11/2= 5.5

Answer : The median of the given set of data of values is, 5.5

Step-by-step explanation :

Median : It is the middle term that is sorted by the list of numbers. It is determine by placing the numbers in increasing order.

For odd observations the formula will be:

For even observations the formula will be:

As we are given that the set of data:

1, 2, 3, 4, 5, 6, 7, 8, 9, 10

Now we have to determine the median.

For even data:

Middle two values are, 5 and 6

Thus, the median of the given set of data of values is, 5.5

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
