The cardinality of a sample space means the size of the sample space.
Event A: There are only 2 possible outcomes. Cardinality is 2.
Event B: There are 5 possible outcomes. Cardinality is 6.
14/74 in the simplest form is 7/37
You have to shoe that the angles between adjacent sides = 90 degrees. You do do this by showing the adjacent sides are perpendicular by comparing their slopes.
Answer:
C and E
Step-by-step explanation:
We are given that



A.

Hence, it is not in proportional relationship with (0.2,0.3)
B.(2.7,4.3)


Hence, it is not in proportional relationship with (0.2,0.3).
C.(3.2,4.8)


Hence, the ordered pair (3.2,4.8) are in a proportional relationship with (0.2,0.3).
D.(3.5,5.3)

Hence, the ordered pair (3.5,5.3) are not in a proportional relationship with (0.2,0.3).
E.(5.2,7.8)

Hence, the ordered pair (5.2,7.8) are in a proportional relationship with (0.2,0.3).
2481.7
^ is the tenth place.
The 5 would either round it up or down by one-tenth. Since we like big numbers... we'll round it to 7 from 6.
