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 %.

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

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.

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.

A. Since the question is asking for the ratio of new books to used books, you need to know the number of used books and new books.

Used books: 14-5=9 //////////// New books: 5

Therefore the answer is 5:9 or 5/9.

B. 14:9 or 14/9

Hope this answer helped you.

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.

QUESTION POSTED AT 15/12/2019 - 10:11 PM

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.

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.

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

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.

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.
