8/9=?/18 find another name for the given number, but with the denominator indicated. Use multiplication by 1.

16

Step-by-step explanation:

8/9 = ?/18

Let the missing value be c

8/9 = c/18

Cross multiply

9c = 18 x 8

9c = 144

Divide both sides by 9

c = 144/9

c = 16.

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
