Answer:

1. The answer for the first question is c.

2. The answer for the second question is d.

Step-by-step explanation:

1. The idea to solve this exercise is to evaluate the given functions in the points {1,2,3,4,5} (notice that these are the x component of the ordered pairs) and then eliminate the different possibilities.

  • The option a. cannot be because 1²=1, which is different from 2 (recall the ordered pair (1,2)).
  • The option b. cannot be because 2*3=6, which is different from 8 (recall the ordered pair (3,8))
  • The option c. is the answer, notice that 2¹=2, 2²=4, 2³=8, 2⁴=16 and 2⁵=32.
  • The option cannot be, because 1+2=3, which is different from 2 (recall the pair (1,2)).

2. The idea is the same of the above.

  • The option a. cannot be because 1²=1, which is different from 16 (recall the pair (1,16)).
  • The option b. cannot be because 2+15=17, which is different from 25 (recall the pair (2,25)).
  • The option c. cannot be because 2(1+3)=8, which is different from 16 (recall the pair (1,16)).
  • By elimination this should be the correct answer. Anyway, it is no difficult to check that (1+3)²=16, (2+3)²=25, (3+3)²=36, (4+3)²=49 and (5+3)²=64.

Stacy rolls a pair of six-sided fair dice.
Nutka1998 [239]

Answer:

The probability that the sum of the numbers rolled is either a multiple of 3 or an even number is 24/36 = 2/3

The two events are mutually exclusive

Step-by-step explanation:

we first need to create a table of the sample space from the experiment, the sum of the numbers rolled. Find the attached for a depiction of the possible outcomes.

The probability that the sum of the numbers rolled is either a multiple of 3 or an even number will be given by counting the numbers that are either even or multiples of 3 and then dividing by the number of possible outcomes, 36.

In our case this will be;

24/36 = 2/3
