4. Consider the temperature in a classroom throughout any given day. Suppose that the
temperature constantly cycles between 68°F and 80°F and is given by the sinusoidal function
f(0) = Acos(Bt) + C, where t=the number of hours after midnight. The temperature starts at
68°F at midnight and first returns to 68°F at 8am.
a) Sketch the graph of the function for two full periods.

the answer is 13/48

step-by-step explanation:

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
