Dr. Ramirez just started an experiment. He will collect data data for 7 days. How many hours is this?

the answer is 168.

Step-by-step explanation:

7 times the number of hours in a day (24) equals 168.

Edit: i edited the answer to avoid any confusion my original answer was wrong.

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
