5 0

Answer:

P = 4/9

Step-by-step explanation:

Event A1: The first dice shows a factor of 12. P(A1) = 4/6 = 2/3

Event A2: The second dice shows a factor of 12. P(A2) = 4/6 = 2/3

P (A1*A2)=4/9

Hey!

-----------------------------------------------------------------

We know that (a = -3), (b = 2), (c = 5), (d = -4).

Solution:

=\frac{ab}{d}

=\frac{(-3)(2)}{-4}

=\frac{-6}{-4}

=1\frac{1}{2}

-----------------------------------------------------------------

Answer:

1 1/2

Find the missing segment in the attached image
uranmaximum [27]

Answer:

25 units

Step-by-step explanation:

This problem can be solved by using concept of Basic proportionality theorem.

This theorem states that if there is line drawn parallel to any side of the triangle, and it intersect the other two sides, then

segment divided on those two sides are in equal proportion.

Let naem this triangle

the side containing 15 and 6 be AB, with A be point on segment having length 15 units

B be  point on segment having length 6 units

c be point on segment having length ? units

DE line parallel to BC

Thus, if apply Basic proportionality theorem. in this then ratio formed will be

15/6 = ?/10

5/2 = ?/10

?= 5/2* 10 = 25

The length of missing segment is 25 units.
