(2 points) Let B = {b1, b2} and C = {c1, c2} be bases for R 2 , find the change-of-coordinates matrix from B to C and the change-of -coordinates matrix from C to B, where b1=[7 5] , b2=−[3 −1 ] c1= [1 −5] , c2= [ −2 2]

seems like d

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
