Prehistoric pottery vessels are usually found as sherds (broken pieces) and are carefully reconstructed if enough sherds can be found. Information taken from a study provides data relating x = body diameter in centimeters and y = height in centimeters of prehistoric vessels reconstructed from sherds found at a prehistoric site. The following Minitab printout provides an analysis of the data. Predictor Coef SE Coef T P Constant -0.203 2.429 -0.09 0.929 Diameter 0.7648 0.1771 5.33 0.005 S = 4.28980 R-Sq = 70.3% (a) The standard error $S_e$ of the linear regression model is given in the printout as \"S.\" What is the value of $S_e$? 4.28980 (b) The standard error of the coefficient of the predictor variable is found under \"SE Coef.\" Recall that the standard error for b is $\frac{S_e}{\sqrt{\sum x^2 - \frac{(\sum x)^2}{n}}}$. From the Minitab display, what is the value of the standard error for the slope b?

25 points Question 1 Unlimited tries (Locate the largest element) Write the following method that returns the location of the largest element in a two-dimensional array. public static int[] locateLargest(double[][] a) The return value is a one-dimensional array that contains two elements. These two elements indicate the row and column indices of the largest element in the two-dimensional array. If there are more than one largest element, return the smallest row index and then the smallest column index. Write a test program that prompts the user to enter a two-dimensional array and displays the location of the largest element in the array. Sample Run Enter the number of rows and columns of the array: 3 4 Enter the array: 23.5 35 2 10 4.5 3 45 3.5 35 44 5.5 9.6 The location of the largest element is at (1, 2) Class Name: Exercise08_13 If you get a logical or runtime error, please refer https://liveexample.pearsoncmg.com/faq.html.

Let $f(x) = x^3 - 5x^2 + 1$. Fill in the values or intervals below. If there is nothing applicable for a given category enter NONE. For $\infty$ use infinity. For $-\infty$, use -infinity. To indicate a union of intervals, use U. interval(s) on which $f$ is increasing interval(s) on which $f$ is decreasing $x$-coordinates of all local maxima $x$-coordinates of local minima interval(s) on which $f$ is concave up interval(s) on which $f$ is concave down Use your results, as recorded above, to sketch the graph of $f$. Check by making a plot (not submitted).
