Provide the answer as a decimal

olga55 [171]

Answer:

0.55

Step-by-step explanation:

The right-hand column of the table gives us the probabilities of the probability function. We know from elementary probability theory that the "probability" of any event(s) happening would be from 0 to 1 inclusive.

The total probability of all events would add up to 1. So, we look at the probabilities given for each even, x, and add them:

0.29 + 0.09 + 0.03 + 0.04 = 0.45

All of these probabilities and the probability at x = 2 (the unknown) would add up to 1, so we can say:

0.45 + probability (x = 2) = 1

Probability at x = 2 = 1 - 0.45 = 0.55

5. Carla babysits and tutors to make extra money. She babysits for $5 an hour and tutors for $10 an hour.

HACTEHA [7]

Carla can babysit for 5 hours and tutor for 7 hours or babysit for 8 hours and tutor for 5.5 hours

<h3>How to graph the inequality?</h3>

Let x represents hours babysitting and y represents hours tutoring

So, we have:

Earnings = Rate of babysitting * x + Rate of tutoring* y

This gives

Earnings = 5x + 10y

He wants to earn at least $95.

This means that:

5x + 10y ≥ 95

See attachment for the graph of the inequality

From the attached graph, two possible solutions are: (5, 7) and (8, 5.5)

This means that Carla can babysit for 5 hours and tutor for 7 hours or babysit for 8 hours and tutor for 5.5 hours
