Consider the system of equations -10x1 + 4x2 = 0 15x1 - 6x2 = 0 as you did in the previous exercise, enter the corresponding matrix c and column vector d into matlab. then type in > > x = c\d note the strange output. include it in your write-up. now go ahead and solve this system by hand. how many free variables do you have in your solution? based on your answer, can you explain why you got the error message when trying to use the command x = c\d?

Find the value of x. give reasons to justify your solutions! c ∈ ae

Name and describe the three most important measures of central tendency. choose the correct answer below. a. the mean, sample size, and mode are the most important measures of central tendency. the mean of a data set is the sum of the observations divided by the middle value in its ordered list. the sample size of a data set is the number of observations. the mode of a data set is its highest value in its ordered list. b. the sample size, median, and mode are the most important measures of central tendency. the sample size of a data set is the difference between the highest value and lowest value in its ordered list. the median of a data set is its most frequently occurring value. the mode of a data set is sum of the observations divided by the number of observations. c. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is the product of the observations divided by the number of observations. the median of a data set is the lowest value in its ordered list. the mode of a data set is its least frequently occurring value. d. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is its arithmetic average. the median of a data set is the middle value in its ordered list. the mode of a data set is its most frequently occurring value.

Collin did the work to see if 10 is a solution to the equation r/4=2.4
