Determine whether the pair of actions results in independent or dependent events. Serena picks one marble out of a bag. Then, af
harina [27]

Answer:

B) Independent; the 1st marble selection will not affect the 2nd marble selection.

Step-by-step explanation:

When finding the probability of events in mathematics, we have both independent and dependent events.

Independent events are events that occur when the results of selection of the first events does not affect the results or outcomes of the second events.

Dependent events are the opposite of Independent events. They are events that occur when the results or outcomes obtained from the second events is affected by the results or outcomes from the selection of the first events.

From the question, we can see that the first event is she picked one marble from the bag. The second event is she replaced the marble before picking another marble. By doing this, the total number of possible outcomes for the probabilities of both events remains the same and they are unaffected.

Therefore, we can say that the two events are Independent because the 1st marble selection will not affect the 2nd marble selection.

1. The amount of money Travis earns is given in the table.
Anastaziya [24]

Answer:

  $250

Step-by-step explanation:

The numbers in the table indicate a proportional relationship between earnings and hours worked. Among other things, that means you can find the earnings for 20 hours by using any table values that sum to 20 hours.

For example, 9 hours + 11 hours = 20 hours, so the earnings would be ...

  $112.50 +137.50 = $250.00 . . . for 20 hours

You could also use 4×5 hours = 20 hours, so ...

  4×$62.50 = $250 . . . for 20 hours

__

Or, you can figure ...

  $37.50/(3 h) = $12.50/h

so the pay for 20 hours is ...

  (20 h)×($12.50/h) = $250.00
