Answer:

0.7070707070 is not an irrational number

Step-by-step explanation:

Irrational numbers cannot be expressed as a ration. These numbers are non repeating and non terminating. For example π is an irrational number.

In the given number 0.7070707070, we can see that 70 is repeating and it terminates as well.

Therefore, from the above definition of irrational numbers we can conclude that the number 0.7070707070 is not an irrational number because it terminates as well as repeated.

Using conditional probability, it is found that there is a 0.035 = 3.5% probability that a hospital patient has both Medicare and Medicaid.

<h3>What is Conditional Probability?</h3>

Conditional probability is the probability of one event happening, considering a previous event. The formula is:

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this problem, the events are:

Event A: Patient has Medicare.

Event B: Patient has Medicaid.

For the probabilities, we have that:

35% of the patients have Medicare, hence $P(A) = 0.35$ .

Of those who have Medicare, there is a 10% chance they also have Medicaid, hence $P(B|A) = 0.1$ .

Then, applying the conditional probability:

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

$0.1 = \frac{P(A \cap B)}{0.35}$

$P(A \cap B) = 0.35(0.1)$

$P(A \cap B) = 0.035$

0.035 = 3.5% probability that a hospital patient has both Medicare and Medicaid.

Three more than five times a number is less than or equal to eight?how do you write that in numbers?

Korolek [52]

3 + 5x ≤ 8 is how this would be displayed in numbers.

To solve, we treat this like an algebraic equation.

Subtract 3 from both sides.

5x ≤ 5

Divide both sides by 5.

x ≤ 1

The value of x is less than or equal to 1 to make the inequality true.

A Campus Republicans fundraiser offers raffle tickets for $14 each. The prize for the raffle is a $400 television set, which mus

Answer:

## Profit/Loss = $14x-400$

## 29 tickets

Step-by-step explanation:

Profit/Loss is Revenue - Cost

For the fundraisers:

Revenue comes from tickets sold at $14 each

x tickets sold, means the revenue is:

14x

Now, cost is what they are going to give out, that is $400 TV Set, so the cost is:

400

Hence, Profit/Loss would be:

Profit/Loss = $14x-400$

Raffle sales equaling the cost of prize is basically when we break-even, or when profit/loss is equal to 0. So we solve the equation:

Profit/Loss = 14x - 400

0 = 14x - 400

14x = 400

x = 28.57

We can't sell fractional tickets, so we have to sell 29 tickets in order to break even
