John’s piggy bank contained 7 dimes and 3 quarters. He pulled out 1 coin without looking. Without replacing the first coin, John then pulled out a second coin. What is the probability that both coins were dimes? Express your answer in simplest form.

We have to find the probability that both coins John pulled from the piggy bank were dimes. At start the piggy bank contained 7 dimes and 3 quarters ( 10 coins in total ). The probability that the first coin pulled out was a dime : 7 / 10 ( 7 favourable of 10 possible outcomes ). So if he pulled out a dime there left: 6 dimes and 3 quarters ( total: 9 coins ). The probability that the second coin pulled out was a dime : 6 / 9 ( 6 favourable of 9 possible outcomes ). Filnally: P = 7 / 10 * 6 / 9 = 42 / 90 = 7 / 15 = 0.467 = 46.7%. Answer: The probability is 7 / 15 or 46.7 %.

Probability Trees - See linked image

A good visual method for this is a probability tree.

Each set of branches represents the probabilities of on coin being removed, the second set is out of 9 as the first coin is taken and not replaced.
Multiply along the lines to work out the probability of each of the combinations.

*Even though only 'Dime Dime' is needed, it is best to do all of them as this way you are able to get all marks in an exam; you can also add up all the final values as a check to see if you are right.

QUESTION POSTED AT 15/12/2019 - 10:43 PM

Ramon was studying pond life in Doyle Park. In two hours, he counted four more frogs than turtles. The number of crayfish he counted was three more than the twice the number of turtles. In total he counted 54 turtles and crayfish. How many frogs were there?

Let us assume the number of turtles = x
Then
Number of frogs = x + 4
Number of crayfish = 2x + 3
Total number of turtles and crayfish = 54
Then we can write the equation as
x + 2x + 3 = 54
3x + 3 = 54
3x = 54 - 3
3x = 51
x = 51/3
   = 17
Then
The number of frogs = x + 4
                                  = 17 + 4
                                  = 21
So there are 21 frogs in the pond that has been counted by Ramon.

Used books: 14-5=9 //////////// New books: 5
Therefore the answer is  5:9 or 5/9.

The costume designer for the school play uses 4 feet of fabric to make 8 costumes. at the same rate, how many costumes can the designer make with 3 yards of fabric?

Well the first thing you need to know is that there are 3 feet in 1 yard. Therefore 3 yards is equal to 9 feet of fabric. The next thing you need to know is how many costumes she can make with 1 foot of fabric which is just 8 divided by 4 so your answer is 2. Then you just multiply 9 and 2 to get 18 costumes. Therefore the designer can make 18 costumes with 3 yards of fabric if she goes at the same rate.

Each week, Rosario drives to an ice skating rink that is 120 miles away. The round-trip takes 2.75 hours. If he averages 55 miles per hour on his way to the rink, which equation can be used to find x, the number of miles per hour he averages on his way home?

While going to the ice skating rink,
Rosario drives a distance of 55 miles in = 1 hour
Then
While going to the ice skating rink,
Rosario drives a distance of 120 miles in = (1/55) * 120                                                                                                          = 2.18 hours
The number of miles per hour Rosario averages while coming back home = x Total up and down time taken by Rosario = 2.75 hours
Then time taken by Rosario to come back
home from ice skating rink = (2.75 – 2.18) hours                                                      = 0.57 hours
Then we can write the equation as
 x = 120/0.57 miles/hour   
    = 210.53 miles/hour

So the average speed of Rosario while coming back home from ice skating rink is 210.53 miles per hour.

Meena sells apple pies at the farmers market. She charges $12 for each pie. It costs her $5 to make each pie, and there is a $35 fee she must pay each week to have a booth at the market. Suppose the fee to have a booth at the farmers market increases to $40. Will the new fee increase the number of pies Meena will have to sell in order to make a profit? Explain your reasoning

Well really it depends on how many pies she sold a week, lets says that she sells six a week then she makes 72 dollars, then minus 30 for the money it takes to make the pies, then minus 40 for the fee to have a booth at the farmers market. Her product is 2 dollars per week, it's not much but it's a profit.

QUESTION POSTED AT 15/12/2019 - 09:44 PM

Of the 50 tables in a restaurant, 40% seat 2 people. The rest of the tables seat 4 people. How many seats are there in the restaurant?

For this case, the first thing we must do is determine the number of tables that 2 people sit.

For this, we use the following rule of three:

50 tables -----------------> 100%

x ----------------------------> 40%

Clearing x we have:

 x = (\frac{40}{100}) * (50)\\x = 20

Then, the number of tables that 4 people feel is given by:

 50 - x = 50 - 20 = 30

We are now looking for the number of chairs:

Table for 2:  20 * 2 = 40

Table for 4:  30 * 4 = 120

Total seats:   120 + 40 = 160

Answer:

there are 160 seats in the restaurant

A train traveled 1/5 of the distance between two cities in 3/4 hour. At this rate, how many hours will it take the train to travel the entire distance between these two cities

Answer: 3\dfrac{3}{4}\text{ hours}

Step-by-step explanation:

Let x denotes the number of hours to cover the entire distance between these two cities .

Using formula \text{Speed}=\dfrac{\text{Distance}}{\text{Time}}, we have

\text{Speed}=\dfrac{1}{x}  (1)

Given : A train traveled \dfrac{1}{5} of the distance between two cities in \dfrac{3}{4} hour.

Then,

\text{Speed}=\dfrac{\dfrac{1}{5}}{\dfrac{3}{4}}=\dfrac{1}{5}\times\dfrac{4}{3}=\dfrac{4}{15}   (2)

From (1) and (2), we have

\dfrac{4}{15}=\dfrac{1}{x}\\\\\Rightarrow\ x=\dfrac{15}{4}=3\dfrac{3}{4}\text{ hours}

Hence, it will take 3\dfrac{3}{4}\text{ hours} to complete the entire distance between these two cities.

How do you find 40 percent of 65


You need to remember a couple of things:

-- ' 40% ' means ' 0.40 ' .

-- In math, the word 'of' almost always means 'times'.

So  " 40% of 65 "  means  " 0.40  x  65 " . 

You can do that easily with your pencil or your calculator.

Someone is reading a book that is 347 pages long....But he or she is on page 203........So what is the percent of the number does this person has to read left?

33. Someone is reading a book that is 347 pages long. But he or she is already on page 203.Now, let’s find the percentage rate of the remaining number of pages. => 347 pages = 100% => 203 is the pages that he or she already read. Solve: => 347 – 203 = 144 pages left. Now, let’s find the percentage of 144 pages out of 347 pages => 144 / 347 = 0.41 => 0.41 * 100% = 41% Thus, he or she still need to read around 41% of the book

Alexis counted 16 commercials while watching 30 min of tv. At this rate, how many commercials would play in a day

There are several information’s that are actually of immense importance, already given in the question. Based on these information’s the answer to the question can be easily deduced.We already know that 
24 hours = (24 * 60 ) minutes
               = 1440 minutes
Then
In 30 minutes the number of commercials shown =16
so 
In 1440 minutes the number of commercials shown = (16/30) * 1440
                                                                                    = 768
So the number of commercials shown in 24 hours is 768.
