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

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
