This is an ungraded practice prompt. ### Twice-Differentiable Functions and Analysis#### Table of Values:The table provided lists values for $ x $, $ f(x) $, $ f'(x) $, $ g(x) $, and $ g'(x) $ for selected values of $ x $. | $ x $ | $ f(x) $ | $ f'(x) $ | $ g(x) $ | $ g'(x) $ ||--------|------------|-------------|------------|-------------|| 1 | 6 | -2 | 1 | 10 || 2 | 4 | -8 | 12 | -9 || 3 | 1 | -3 | 3 | 2 || 4 | -1 | 2 | -8 | -4 |#### Problem Analysis:The functions $ f $ and $ g $ are twice-differentiable for all real numbers and exhibit continuous second derivatives. The graph of $ f $ is strictly decreasing. We are given values of $ f $, $ f' $, $ g $, and $ g' $ for specific $ x $ values. Define $ h $ as $ h(x) = f(x) \cdot g(x) $.#### Questions:a) **Explain why there must be a value $ a $ for $ 1 < a < 4 $ such that $ h(a) = 7 $****Answer:** By the Intermediate Value Theorem, if $ h(x) $ is continuous and takes different values at two points, then it must take every value between them at some point in the interval. Given $ h(1) = f(1) \cdot g(1) = 6 \cdot 1 = 6 $ and $ h(4) = f(4) \cdot g(4) = (-1) \cdot (-8) = 8 $, and 7 is between 6 and 8, there exists some $ a $ in $ (1, 4) $ such that $ h(a) = 7 $.b) **Find $ h'(3) $****Answer:** The derivative of $ h(x) $ is \( h

You may need to use the appropriate appendix table to answer this question. Alexa is the popular virtual assistant developed by Amazon. Alexa interacts with users using artificial intelligence and voice recognition. It can be used to perform daily tasks such as making to-do lists, reporting the news and weather, and interacting with other smart devices in the home. In 2018, the Amazon Alexa app was downloaded some 2,800 times per day from the Google Play store.† Assume that the number of downloads per day of the Amazon Alexa app is normally distributed with a mean of 2,800 and standard deviation of 860. (a) What is the probability there are 1,900 or fewer downloads of Amazon Alexa in a day? (Round your answer to four decimal places.) (b) What is the probability there are between 1,600 and 2,400 downloads of Amazon Alexa in a day? (Round your answer to four decimal places.) (c) What is the probability there are more than 2,900 downloads of Amazon Alexa in a day? (Round…

The Census Bureau Web site gives several choices for "average income" in its historical income data. In 2006, the median income of American households was $48,201. The mean household income was $66,570. The median income of families was $58,407, and the mean family income was $77,315. The Census Bureau says, “Households consist of all people who occupy a housing unit. The term ‘family’ refers to a group of two or more people related by birth, marriage, or adoption who reside together.” Identify the reason for mean incomes for households being higher than median incomes for households.
Give five different numbers whose mean is 11 and range is 14.
