for one file:
For X = 1,
P(~A and B)
or
P(A and ~B) =
0.6 * 0.3 + 0.4*0.7 = 0.46
Oh, I think I see, the universe for P(A and B) is first
or
second file
while P(~A and B) or P(A and ~B) the universe is first, second or no

The order of the letters is very important when we explain the congruence of two triangles.
<span>Triangle DEF is congruent to right triangle GHI means that the following pairs of angles are congruent:
{D, G}, {E, H}, and {F, I}, according to the order of the letters. Thus, in triangle DEF, E is a right angle.
This means that the line segments </span>
and
are perpendicular.
As we know that the product of the slopes of 2 perpendicular lines (or line segments) is -1, and since the slope of the side DE is -2, then the slope of the side EF must be -1/(-2)=1/2.
Since the sides EF and HI are congruent according to our discussion above, then, the slope of the side HI is also 1/2.
Answer: A and B
No she is not right.
Dividing blocks by minutes would be 12/36 = 1/3
The ratio would be 1:3 meaning she runs 1 block every 3 minutes.
Number 5 is 3.8
number 6 is yes, she will bc if you multiply 14,2 by 8, it will be less than 88.3
number 7 is about .11
number 8 is about 4.285
