Random question you dont have to answer but get free points Do you know the difference between the diameter and radius of a circle if you do can you explain it to me and draw me an example of each? Then help me answer the following questions:

Draw a circle that has a diameter of 24.
Draw a circle that has a radius of 25.
If the radius of a circle is 20cm what is the diameter.
If the diameter of a circle is 25 what is the radius of the circle.
When given the radius of 8 ft. find the area of the circle.
When given the radius of 14cm find the circumference.
When giving the diameter of 15cm find the radius.
The circumference of a circle is 72.22ft find the area.
The circumference of a circle is 91.06 find the area.

(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?
