In this activity you will perform matrix operations to solve problems. Part A Table 1 contains data on unit sales of notebook computers by three sales teams of Computer Gear Corporation in three cities for the first quarter of last year. Table 2 contains the sales data for the second quarter. Table 1: First Quarter Sales City Team A Team B Team C New York City 112 89 101 Chicago 78 82 43 Phoenix 91 96 103 Table 2: Second Quarter Sales City Team A Team B Team C New York City 81 63 92 Chicago 68 72 56 Phoenix 71 76 89 Use matrices to compute the midyear sales report. What does the middle entry, C22, of the resultant matrix represent?

step-by-step explan mxfcg'k; uafwgzfgjhklhgation:

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
