Answer: The value of n = 7.
Step-by-step explanation:
Since we have given that
Number of beads is to selected = 20
Number of dozen each of n different colored beads = 2
Number of different colored beads = n
With repetitions of colors allowed.
Number of ways = 230,230
So, it becomes
now,
By hit and trial we get that
Hence, the value of n = 7.
Answer:
The required co-ordinate is (-2, -5).
Step-by-step explanation:
For a given point, reflection of a point (x, y) across a horizontal line y = k, the reflected co-ordinates will be: .
Here, (x, y) = (-2, 7) then reflection along the line y = 1, we get:
= (-2, -5)
The reflected point is (-2, -5).
