Please help! Correct answer only, please! Consider the matrix shown below: Find the determinant of the matrix A. Group of answer choices A. The Determinant cannot be found for a matrix with these dimensions B. 11 C. 7 D. 23

d) 23

Step-by-step explanation:

Consider matrix . The determinant is: ad - bc

In the matrix given, a = 5, b = -1, c = 3, d = 4

det A = ad - bc

        = 5(4) - 3(-1)

        = 20 - (-3)

        = 20 + 3

        = 23

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
