Given the graph with nodes a... f, construct its adjacency matrix A. Make sure to list the nodes in alphabetical order. Write your adjacency matrix with pen and paper. a b f C d e Now, enter your adjacency matrix A below by entering each row of A as a sequence of numbers separated with comas "," Row 1: Row 2: Row 3: Row 4: Row 5: Row 6:

Plot the following points on the scatter diagram:{(0,2),(1,1),(2,4),(3,3),(4,4),(5,7),(6,3),(7,5),(8,10),(9,7),(10,7)}. Plot the points carefully and use the "Remove Last Point" button to replot a point if you make an error. What is the approximate correlation coefficient (r) for your scatter diagram? Between .50 and .69Between .70 and .89Between .90 and 1

This network represents the distribution of dried fruit used to make cake from 2 wholesalers to 3 bakeries. Nodes A and B are the wholesalers and nodes X, Y and Z are 3 bakeries. The decimal number on each arc shows the proportion of fruit sent from each wholesaler to each bakery ie. 25% of the fruit from wholesaler A is sent to Bakery Z. Write down the matrix which represents this network and then use this matrix to determine the amount of dried fruit received by bakeries X, Y and Z if 450 kg of dried fruit is distributed from wholesaler A and 750 kg is distributed from wholesaler B.

A researcher collected data on how much extra sleep subjects got after being placed into one of two groups. Each group received a different set of mediation exercises.  The dataset they collected is called df and the first 6 rows are shown here: Which lines of code are required to make the plot above?   Click all that apply. a. geom_boxplot(alpha = .3) b.  geom_jitter(width=.1, size = 2, color = "navy") c. geom_boxplot(fill = "dodgerblue", alpha = .3)   d. geom_jitter(color = "navy")   e. ggplot(sleep, aes(x = group, y = extra))   f. theme_classic()

Construct two histograms showing the distribution of prices for homes without central air and the prices for homes with central air.First, create the two columns of data. On the Data worksheet, copy the Price column to columns P and Q. In cell P1, type Price without central air. In cell Q1, type Price with central air. Then select the first row, go to the Home tab of the Ribbon, and select Sort&Filter in the Editing group. Select Filter in the drop-down menu. In cell E1, open the drop-down menu and select to show only value 0. Delete all of the filtered values in column Q. Then in cell E1 in the drop-down menu, select to show only value 1. Delete all of the filtered values in column P. Go back to cell E1 and select to show all values.Construct the histogram using Data Analysis for the Price without central air column using the Binsize column K (starting on cell K1). Choose cell R1 on the Data worksheet as the output range. Be sure to check the ‘Labels’ and ‘Chart Output’ boxes in…

The entirety of the data set will be in the two pictures
