At the rolling ridge school spelling bee, 75% of the
contestants advanced to the second round and 60% advanced
to the third round. what is the probability that a randomly
selected contestant advanced to the third round given the same
contestant advanced to the second round?
a. 3/20
b. 9/20
c. 7/15
d. 4/5

Option D

Step-by-step explanation:

Call A to the event in which a student advances to the second round.

We know that:

Call B the event in which a student advances to the third round.

We know that:

We then look for the probability of B given A. This is:

In this case, the probability of B and A is equal to the probability of B, since the students who advance to the third round also advanced to the second round before

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.
