Patterns are found all around us. In this lesson, we will discuss how these patterns and linear functions can be related. Take a look at the block patterns
below. Make a prediction of how many blocks would be needed to create the
next pattern. Make sure to explain your reasoning How could you determine
how many blocks are in the 10th pattern? Can you write an equation or a rule
for how to determine the amount of blocks needed for any pattern?

What values of x satisfy the inequality x^2-9x< 0? how is your answer shown on the graph?

(20 points) a bank has been receiving complaints from real estate agents that their customers have been waiting too long for mortgage confirmations. the bank prides itself on its mortgage application process and decides to investigate the claims. the bank manager takes a random sample of 20 customers whose mortgage applications have been processed in the last 6 months and finds the following wait times (in days): 5, 7, 22, 4, 12, 9, 9, 14, 3, 6, 5, 15, 10, 17, 12, 10, 9, 4, 10, 13 assume that the random variable x measures the number of days a customer waits for mortgage processing at this bank, and assume that x is normally distributed. 2a. find the sample mean of this data (x ě…). 2b. find the sample variance of x. find the variance of x ě…. for (c), (d), and (e), use the appropriate t-distribution 2c. find the 90% confidence interval for the population mean (îľ). 2d. test the hypothesis that îľ is equal to 7 at the 95% confidence level. (should you do a one-tailed or two-tailed test here? ) 2e. what is the approximate p-value of this hypothesis?
