Numerical Problem: Password Strength Analysis As a cybersecurity analyst, you understand the importance of using strong and unique passwords for online security. Here, you will evaluate the strength of a password based on certain criteria. Consider the following password: PurpleBanana123$ Calculate the strength of this password based on the following criteria: 1. Length: Each character contributes 4 points to the password strength. 2. Uppercase Letters: Each uppercase letter adds 8 points. 3. Lowercase Letters: Each lowercase letter adds 6 points. 4. Numbers: Each number adds 10 points. 5. Special Characters: Each special character adds 12 points. Calculate the total strength score for the password PurpleBanana123$ Hint: After calculating points for each of the 5 criteria, add them together.

a) Use the Laws of Logarithms to expand the expression. log(sqrt(x*sqrt(y*sqrt(z)))) b) Use the Laws of Logarithms to combine the expression. 2(log5x + 2log5y - 3log5z) Solve the equation for x. a) 3^(4x) - 3^(2x) - 6 = 0 b) log4(x+2) + log4(3) = log4(5) + log4(2x-3) Application section 10.2 A gas station sells three types of gas: Regular for $3.00 a gallon, Performance plus for $3.20 a gallon, and Premium for $3.30 a gallon. On a particular day, 6500 gallons of gas were sold for a total of $20,050. Three times as many gallons of regular as Premium gas were sold. How many types of each gas were sold that day.

A developer wants to know if the houses in two different neighborhoods were built at roughly the same time. She takes a random sample of six houses from each neighborhood and finds their ages from local records. The accompanying table shows the data for each sample (in years). Test the null hypothesis that the mean age of houses in the two neighborhoods is the same. Assume that the data come from a population that is Normally distributed. Complete parts a through f below. Click the icon to view the data table. a) Find the value of the t-statistic for the difference, $\bar{y}_1 - \bar{y}_2$, in sample mean ages for the null hypothesis. t= \boxed{} (Round to two decimal places as needed.) b) Calculate the degrees of freedom from the formula $df = \frac{\left(\frac{s_1^2}{n_1} + \frac{s_2^2}{n_2}\right)^2}{\frac{1}{n_1 - 1}\left(\frac{s_1^2}{n_1}\right)^2 + \frac{1}{n_2 - 1}\left(\frac{s_2^2}{n_2}\right)^2}$. df = \boxed{} (Round to two decimal places as needed.) c) Calculate the degrees of freedom using the rule that df = min($n_1$ - 1, $n_2$ - 1). df = \boxed{} (Type a whole number.) d) Find the P-value using the degrees of freedom from part b. P= \boxed{} (Use the answer from part b to find this answer. Round to three decimal places as needed.) e) Find the P-value using the degrees of freedom from part c.
