A bag contains 3 blue marbles and 4 yellow marbles. You pull out one
marble, do not replace it, and then pull
out another one. What is the probability
that the first marble is yellow and the
second one is blue? In simplest form

2/7

Step-by-step explanation:

Probabilty 1 = 4/7

Probability 2 = 3/6 = 1/2 (because if you not replace it, there is one less

final probability = 4/7 * 1/2 = 4/14 = 2/7

168

step-by-step explanation:

i am pretty sure that the answer is 168

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
