Which of the following relations has a domain of {1, 4, 5}? choose all that apply.

a) {(1, 3), (4, 2), (5, 2), (4, 1)}

b) {(4, 1), (5, 4), (6, 4), (2, 5)}

c) {(0, 1), (3, 5), (5, 4)}

d) {(1, 2), (4, 3), (1, 5), (5, 6)}

probability for j is 1/4

while

a is 1/6

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
