How do you find the rank of product of two matrices?

just make the matrices upper triangular by making the values below the digonal zero,and then find how many minors can be calcuted.......


A Calculate Bowleys coefficient of skewness from the following information equals 34.087156 equals 44.962963 equals 39.606382?

the sum of the upper quartile and lower quartile is 56 and their difference is 24. find upper quartile and lower quartile.


How do you find least upper bound and greatest lower bound (if it exists) of (0)?

The answer depends on the level of accuracy of the value 0.


How do you find the inter-quartile of 7 numbers?

The interquartile range is the difference between the Lower quartile and the upper quartile. Obviously you need to be able to find these values. Haylock (2006) explains how to do this for difficult size groups in mathematics explained for primary teachers. He explains the position of the lower quartile is a quarter of (n+1) and that of the upper quartile is three-quarters of (n+1). So for a group of 7 numbers, you find a quarter of 8, which is 2. Therefore the number in second place is the lower quartile. Three quarters of 8 is 6 and so the number in 6th position is the upper quartile. Now take the lower quartile from the upper quartile.


What is the upper quartile of the numbers 75 80 85 90 95 100 105 110 115 120 125 130 135?

To find the upper quartile (Q3) of the dataset, first, arrange the numbers in ascending order, which they already are. The upper quartile is the median of the upper half of the data. In this case, the upper half consists of the numbers 110, 115, 120, 125, 130, 135. The median of these values is the average of the third and fourth numbers (120 and 125), which is (120 + 125) / 2 = 122.5. Thus, the upper quartile is 122.5.
