Answer:
can you please describe this more and what it is then i will answer it in the comments
Step-by-step explanation:
Answer: 2(4)+3(4)^3≠5(4)4
Step-by-step explanation: i just answered it and I was correct.
In the first slot lets calculate the chance of getting a w: 1/5
In the second slot calculate the chance of getting a o: 1/4 (notice how it's 4 not 5 because you already have one letter in the first slot so you have 4 left to choose from.)
In third slot, chance of getting a r: 1/3
In fourth slot, chance of getting a l: 1/2
In the fifth slot, if you got all the first four letters right, than you would be left with one letter, so your chances are 1/1 (100%) for the fifth slot
To calculate probability multiply all the fractions we got above: 1/5 x 1/4 x 1/3 x 1/2 x 1/1
We will then get: 1/(5x4x3x2x1) = 1/120
1/120 is the probability of the 5 slots showing the word "world"
Area of ABC : AB*AC/2
the maximum of the parabola is reached at x=-4/(2*(-1))=2 hence A is at (2,0) and B is at (2,(-2)^2+4*2+C)=(2,12+C)
C is the second root (x-intersect), which we can find :
determinant1 : D=16-4*(-1)*C=4(4+C) thus the second root is at x=
Hence the area of the triangle is
hence
.
We remark that
Hence 4+C=16 thus
C=12
