Given the following matrices, if possible, determine (bc)a. identify the dimensions of the resulting matrix and fill out the matrix, if it exists. if not, state "not possible". a=[5−16−6] , b=[43] , and c=[−3−287]

triangle abc is reflected on the line x=-6.5 then reflected again on the x axis

step-by-step explanation:

(-1,-0.5)

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
