Answer:

26,000,000 codes

Step-by-step explanation:

To find how many unique codes can be created, we just need to check how many possibilities there are for each letter or digit in the code.

Each letter has 26 possible values, and each digit has 10 possible values, so as we have 1 letter and 6 digits, the total number of unique codes are:

26 * 10 * 10 * 10 * 10 * 10 * 10 = 26,000,000 codes.

Answer:

0.50 \leq \frac{x+2}{x+10}\\

At least 6 strikes

Step-by-step explanation:

The required numerical data is missing from the question. In the original question, Roni gets a strike 2 out of 10 times and her goal is to have a minimum strike rate of 50%. The number of consecutive strikes required is given by the following inequality:

0.50 \leq \frac{x+2}{x+10}\\

Solving the inequality:

0.5x+5 \leq x+2\\3\leq0.5x\\x\geq6

Roni needs at least 6 strikes.

After 6 strikes, she would have 8 out of 16, which equals exactly 50%.
