Which statement is true...

In this assignment you are going to explore how to solve exponential expressions. Make sure you answer all questions in the spaces provided Part A: Finding the Answer In this section, you are going to use the appropriate rule of exponents to find the answer. Simplify means to write the answer as a new exponent. e.g. to simplify 2 x 21 = 21 =27 Evaluate means to write the answer found by using the exponent e.g. to evaluate ?' means 16 In the textbox given, write the steps that you used to solve the problem. Enter the answer on the line to the left of the question number. Each question is worth 2 marks: I mark for the steps and I mark for the correct answer. 1. Express 34 x 3" as a single power. 2. Express 8" + 8' as a single power. 3. Express (-5) as a single power. 43 x (43)3 4. Express as a single power. (0.25) 5. Simplify (0.25) x (0.25) Page 13. The Engineering Department has made a process change. The change is expected to produce a small improvement in process variance. What sort of statistical test is needed to determine if variance has improved? Would this be a lor 2 sided test? The Engineering Manager has requested nancing to collect at least 100 samples. She says based on the statistical test needed she can only test for small changes in variance with such a large sample size. Based on your understanding of the test function's shape explain why you would or would not approve funding. Which of the following statements regarding artificial intelligence are true? Select all that apply. Artificial intelligence is a term used to describe the simulation of natural human intelligence by computer systems. The primary goal of artificial intelligence is to surpass the decision-making skills that are part of natural intelligence. Artificial intelligence research incorporates experts from a variety of disciplines and has seen much progress but also raises ethical concerns. Because humans have perceptive systems, we are able to understand sensory stimuli that cannot be interpreted by artificial intelligence. Artificial intelligence can rarely, if ever, display the creativity and imagination that is part of natural intelligence. Some computers equipped with artificial intelligence systems are able to learn from experiences and apply what they have learned, like humans. Artificial intelligence and natural intelligence are similar in that both are able to solve complex problems through the use of heuristics
