Five friends: Aman, Biman, Chutki, Deep, and Eric went to a market to buy five different food items: Chocolate, Potato chips, Cold drinks, Pizzas, and sweets for their college reunion parties. The number of items bought by them in each of the categories are greater than 19, and less than 30 . The number of items bought by any two friends in the same food categories is distinct. Similarly, the number of items bought by any person in any two food categories is distinct. '*' given in the table denotes the highest or the second highest value of the respective row and column. (There are exactly two '*' values in each row and column, and some of the * values are intentionally left blank.) \begin{tabular}{|c|c|c|c|c|c|} \hline & Chocolate & Chips & Drinks & Pizzas & Sweets \\ \hline Aman & \( 26^{*} \) & & & & 22 \\ \hline Biman & & & \( 27^{*} \) & & \\ \hline Chutki & & \( 23^{*} \) & & \( 25^{*} \) & \\ \hline Deep & & & \( 23^{*} \) & & \\ \hline Eric & & \( 28^{*} \) & & & \\ \hline \end{tabular} The following information is also known: 1. The total number of cold drinks bought by them is equal to the number of pizzas bought by these five friends. 2. The number of chocolates bought by these five friends is a multiple of 13 , and the number of chocolates bought by Biman is a prime number. 3. The total number of sweets is greater than any other food item. 4. Eric bought 8 more sweets than the number of pizzas bought by Biman, and the number of chocolates bought by Chutki is an even number How many total combinations are possible?

Question 13 9 pts The image below shows the data points for the number of Marriages in the U.S. for a given year. Excel has calculated a trendline equation of y = -13.837x + 29972 for this data. Number of Marriages 2000-2015 y = -13.837x + 29972 R$^2$ = 0.624 Use the trend line equation to estimate the number of marriages in 2015. Do not include a label. 2 points Write a sentence that compares the equation's value with the actual value for 2015. 1 point Interpret the meaning of the slope of the trend line in a meaningful sentence. 3 points Classify the correlation as either weak, moderate, or strong. 1 point Should we use this model to predict how many marriages there will be in 2025? Why or Why not? 2 points
