Question 13(multiple choice worth 5 points) (05.06 lc)the net of an isosceles triangular prism is shown. what is the surface area, in square units, of the triangular prism? three rectangles are shown, one below the other. the middle rectangle has a width of 6 units, and, along each width, is a triangle with a height of 4 units. the length of the lowermost rectangle is 8 units and its width is 5 units. 104 units2 132 units2 152 units2 168 units2

Can someone tell me if this is perpendicular? !

The measures of the legs of a right triangle are 15m and 20m . what is the length of the hypotenuse

(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?
