The baseball team has a double-header on Saturday. The probability that they will win both games is 42%. The probability that th
netineya [11]
This problem fits the conditional probability formula very well. The formula is P(B|A) = P(B ∩ A)/P(A). If event A is winning the first game, and event B is winning the second, then P(B ∩ A) = 0.44, and P(A) = 0.6. So P(B|A) is obtained by dividing 0.44 by 0.6, which is about 0.733.

Corey wants to estimate the height of the statue of Stephen F. Austin in Angleton, Texas. He stands approximately 19.3 feet away
aniked [119]

The statute is about 80 feet tall

<h3>Similar triangles;</h3>

In order to get the height of the statute, we will need to get the base of the bigger triangle using the similarity theorem of triangles as shown:

B/19.3 = 19.3/5

5B = 372.49

B = 372.49/5

B = 74.498

<h3>Get the height of the status</h3>

The height of teh status = B + 5

Height of the status = 74.498 + 5

Height of the status = 79.498

Hence the statute is about 80 feet tall
