Witch ones are bigger. <br> a. 5/9 or 11/18<br><br> b. 3/8 or 4/9

Mariulka [41]

Answer:

for a it would be 11/18 and for b it would be 4/9

Step-by-step explanation:

This is because I did the same butterfly method. 5 times 5 times 18 which is 90 for 5/9 and 9 times 18 is 99 for 11/18, you can also write it as 5/9 and 11/18 but cross multiply. This is also what I did with the second one.

Students in a school were surveyed about their study habits. Forty-two percent of students said they study on weeknights and wee

MA_775_DIABLO [31]

Answer:

0.6 = 60% probability that he or she studies on a weeknight.

Step-by-step explanation:

We solve this question treating these events as Venn probabilities.

I am going to say that:

Probability A: Probability of a student studying on weeknights.

Probability B: Probability of a student studying on weekends.

Forty-two percent of students said they study on weeknights and weekends

This means that $P(A \cap B) = 0.42$

47% said they studied on weekends

This means that $P(B) = 0.47$

65% said they study either on weeknights or weekends.

This is $P(A \cup B) = 0.65$

If you were to pick one student at random, what is the probability that he or she studies on a weeknight?

This is P(A), and the equation used is:

$P(A \cup B) = P(A) + P(B) - P(A \cap B)$

Considering the values we have:

$0.65 = P(A) + 0.47 - 0.42$

$0.05 + P(A) = 0.65$

$P(A) = 0.6$

0.6 = 60% probability that he or she studies on a weeknight.

Ruth found 37 tickets for $7. Please help Ruth by figuring out the ratio. (round to 2 decimal places)

Amanda [17]

Answer:

Ratio of ticket to its price is 1 : 0.189.

Step-by-step explanation:

Here, the cost of 37 tickets = $7

Let us find the unit cost of the ticket.

$\textrm{Unit Price } = \frac{\textrm{Total Price of n units}}{\textrm{n}}$

$\implies U = \frac{7}{37}=0.189$

So, the unit price of each ticket = $0.189

Now, ratio of Each Ticket: Unit Price = 1 : 0.189

Hence, the ratio of ticket to its price is 1 : 0.189.
