Answer:
-155
Step-by-step explanation:
a common factor of 5, 15 and 25 is 1 and 5
The total number of possibilities of drawing their names
is given by permutation.
4P4 = 24
The total possibility of drawing their names in
alphabetical is only 1.
Therefore the probability is:
P = 1 / 24
P = 0.0417
<span>Therefore there is about 4.17% chance that it will be in
alphabetical order</span>
Answer:
A. (-4, -3)
B. (5, 3)
C. (-1, 3)
Step-by-step explanation:
Ok, bear with me, its been a while since I have done this so make sure you double check.
A. So, we already know where point A is(1,-3) and we need that to find B
It says we need a reflection which is basically mirroring it across the y-axis(note: if it were across the x-axis then this would turn out much differently.)
Its hard to explain but i will tell you that reflecting point A will give us (-1, -3)
Now we need to translate it 3 units to the left
<u>(-4, -3)</u>
B. Ok, next we have point C which is a reflection using the x-axis (now you will see how important it is to make sure you are reflecting in the right place.) Over the x-axis, will give us (1, 3).
Now we need to translate to the right... (5, 3)
C. Point D... we need to rotate it. Now, rotating is a little bit more work than reflecting and translating but its not hard.
since we are rotating 180 degrees then we are basically just turning it around halfway from 360...
A is (1, -3) so D would be (-1, 3)
Hope this helps :)
