PIT_PIT [12445]

Answer:

Dependent: Total cost of the ride.

Independent: Amount of rides.

Step-by-step explanation:

The independent variable represents what is adjusted, while the dependent variable signifies what alters as a result of that adjustment.

In this case, the total expense for rides fluctuates with any variation in the number of rides taken.

Therefore, the amount of rides is the independent variable whereas the total cost for rides is the dependent variable

On a track and field team, 8% of the members run only long-distance, 32% compete only in field events, and 12% are sprinters onl

lawyer [12517]

Answer:

0.40

Step-by-step explanation:

The percentage of members who engage only in long-distance running is 8%

Therefore, the probability that a member focuses solely on long-distance running is P(A) = 0.08

The percentage of members who participate exclusively in field events is 32%

Thus, the probability of a member competing only in field events is P(B) = 0.32

The percentage of members acting as sprinters is 12%

So, the probability that a member is a sprinter is P(C) = 0.12

We need to determine the probability that a team member is either an exclusive long-distance runner or an only field event competitor, which equates to finding P(A or B). Since these two events cannot occur simultaneously, we can express this as:

P(A or B) = P(A) + P(B)

Substituting the known values results in:

P(A or B) = 0.08 + 0.32 = 0.40

Thus, the likelihood that a randomly selected team member runs exclusively long-distance or participates solely in field events stands at 0.40
