please prove 9.6 and 9.7
The next three theorems formalize what you may have discovered in the preceding group of questions. 9.6 Theorem. Let K be a positive integer Then, among any k real num- bers, there is a pair of them whose difference is within 1/K of being an integer When we take our collection of real numbers to be multiples of an ir- rational number, then we can find good rational approximations for the irrational number. Remember how...

Question For this problem, consider the function on the domain of all real numbers. (a) The value of is Oo . (If you need to use -co or o, enter-infinity or infinity.) (b) The value of f(x) limx→- is O0 X . (If you need to use -oo or co, enter -infinity or infinity.) (c) There are two x-intercepts; list these in increasing order: s- t- (d) The intercepts in part (c) divide the number line into three intervals. From...

A random sample of 88 women showed that the mean number of children reported was 1.58 with a standard deviation of 1.8. (interestingly, a sample of 88 men showed a mean of 1.3 children.) Complete parts (a) through (c) below EEB Click the lcon to view the ttable. Find a 95% confidence interval for the population mean number of children for women. Because the sample size is so large, you can use 1.96 for the critical value of t (which...

What do we mean by “regression toward the mean?” A. The linear regression equation can be used to identify the average value of each variable in the model. B. Linear regression normalizes the scale of the variables so they have a mean of zero and standard deviation of 1. C. The phenomenon that if a variable is extreme on its first measurement, it will tend to be closer to the average on a second measurement. D. Outliers in the model...

Let k 21 be a positive integer, and let r R be a non-zero real number. For any real number e, we would like to show that for all 0 SjSk-, the function satisfies the advancement operator equation (A -r)f0 (a) Show that this is true whenever J-0. You can use the fact that f(n) = crn satisfies (A-r)f = 0. (b) Suppose fm n) satisfies the equation when m s k-2 for every choice of c. Show that )...
