Answer:
(2, 3), (-3, 2), (-2, -3), (3, -2)
Step-by-step explanation:
You can pick any point you like, then rotate it around the origin to the four quadrants (or axes) by the transformation ...
(x, y) ⇒ (-y, x) . . . . . . . . . 90° rotation CCW
That is a rotation 90° CCW. Of course a rotation CW can do the same thing for you.

One possible square is ...
(2, 3), (-3, 2), (-2, -3), (3, -2)
First, start off by listing a few of the numbers that follow the first three clues to see if you can narrow it down.
7,111,111
7,333,333
7,555,555
etc.
Then, start adding up digits to see if you're getting close.
7+1+1+1+1+1+1 = 13
7+3+3+3+3+3+3 = 25
7+5+5+5+5+5+5 = 37
Since 7,555,555 is too high, we step it down to 7,555,333
7+5+5+5+3+3+3 = 31
7,555,333 will work as an answer, as well as 7,333,555, since it's the same amount when the digits are added together.
Answer:
0.68
Step-by-step explanation:
Given that :
P(trombone | snow) = 0.8 ;
P(trombone | no snow) = 0.5
P(snow) = 0.6
P(trombone) = P(trombone | snow) * p(snow) + P(trombone | no snow) * p(no snow)
P(no snow) = 1 - 0.6 = 0.4
Hence,
P(trombone) = P(trombone | snow) * p(snow) + P(trombone | no snow) * p(no snow)
P(trombone) = (0.8 * 0.6) + (0.5 * 0.4)
P(trombone) = 0.48 + 0.20
P(trombone) = 0.68
Answer:
44
Step-by-step explanation:
By substituting x=8 in the equation we get the answer as 44.
