Answer:

x=4.5

Step-by-step explanation:

From AAA, both triangles in this figure are similar. Therefore, we can set up the following proportion:

\frac{x}{9}=\frac{x+3}{15} or \frac{x}{9}=\frac{3}{6}.

Cross-multiplying, we get:

6x=9(3),\\6x=27,\\x=\frac{27}{6}=\fbox{$4.5$}.

If a baseball player get a hit in 31% of his at-bats, what is the probability that he will
solong [7]

Given:

A baseball player get a hit in 31% of his at-bats.

To find:

The probability that he will  get a hit 5 at-bats in a row.

Solution:

Since, a baseball player get a hit in 31% of his at-bats, therefore

Probability that he get a hit = \dfrac{31}{100}

                                           = 0.31

Now, the probability that he will  get a hit 5 at-bats in a row is

P=0.31\times 0.31\times 0.31\times 0.31\times 0.31

P=(0.31)^5

P=0.0028629151&#10;

Therefore, the required probability is (0.31)^5 and it can be written as 0.0028629151 .
