Answer:
D
Step-by-step explanation:
There are 9 letters, which contains 2Qs, 3Ls and 4Bs.
If the 9 letters are distinct, the number of permutations they have will be 9!.
! is the factorial sign.
9! = 9*8*7*6*5*4*3*2*1
HOWEVER, we have some identical elements, so we need to get rid of the permutations of the same letters.
Thus we have:
The answer is D
Answer: m = 1/2
Step-by-step explanation: Let's use the graphing method.
To find the slope of the line using the graphing method,
we first set up a coordinate system.
Next, we plot our two points, (0, 0), which we label point A, and (2, 1),
which we label point B, and we graph our line, as shown below.
Now just graph the line through the two points.
Now, remember that the slope, or m, is equal to the
rise over run from point A to point B.
To get from point A to point B, we rise 1 unit and run 2 units.
So our slope, or rise over run, is 1/2.
