ann picks a 4 digit number . The first digit is not a zero .The 4 digit number is a multiple of 5. how many different 4 digit numbers could she Pick?

Answers

Answer 1

_ _ _ _
since it has to be a four digit number and the restrictions are only two substitue the first digit with 1
1 _ _ _
then substitue the last one with 1 because there is only one multiple of 5 that is a single digit

1 _ _ 1

then substitue the second gap with 8 because 0-9 are ten numbers and since you already used 2 numbers 10-2 is 8
1 8 _ 1

then substitue the last gap with 7 because you already used three numbers

1 8 7 1

then multiply all of them and you get 56

What is the mean,median,mode(s) an range if the numbers are 15,30,17,15,24,31,15

Answers

The mean is 21. The median is 15. The mode is 15. The range is 16.

Hello There!

Mean: Average of numbers in a set of data.

STEP 1: Add the numbers together. In this case, we would add

15 + 30 + 17 + 15 + 24 + 31 + 15 = 147

STEP 2: Divide the sum by the number of digits you added. We would divide

147 "sum of numbers" by 7 "number of digits" and we would get an answer of

21.

The mean for the set of data is 21

Median: The middle number when all the numbers are listed in order.

To find the median, we would put the lowest number on the left and the biggest number on the right and continue to go from least top greatest.

-Least To Greatest-

15-15-15-17-24-30-31

In our set of numbers, we cross out one number from the left and the right each time until we come across one number in the middle. The number that is in the middle in 17.

The median for this set of data is 17

Mode: The number that occurs most often in a set of numbers.

15-15-15-17-24-30-31

Since the number 15 occurs three times, the mode for the set of data is 15.

The mode for this set of data is 15

Range: The difference between the highest and the lowest number.

15-15-15-17-24-30-31

The highest number in the set of numbers is 31 and the lowest number in this set is 15.

31 - 15 = 16

The range for this set of data is 16

Nicholas has a larger tropical fish collection. He gives 2/3 of his fish to a high school. Then he gives 2/5 of the remaining fish to another school. In the end he has 30 fish left. How many fish Nicolas have at first?

Answers

Let the initial count of his fish be n.

He gives away 2/3 of these fish: 2n/3, leaving n/3 fish.

He gives away 2/5 of these remaining n/3 fish: (2/5) times (n/3), or

2n
--- , meaning that (3/5) times (n/3) fish are left.
15

(3/5)(n/3) = n/5 fish left = 30 fish. Thus, n = 150 fish.

Be certain to check this answer!

Final answer:

To find the original number of fish in Nicholas' collection, work backward from the information provided on how many fish he has left after donating to the schools.

Explanation:

Nicholas has a larger tropical fish collection. He gives 2/3 of his fish to a high school, then he gives 2/5 of the remaining fish to another school. In the end, he has 30 fish left. To find the original number of fish, we can work backward:

Let the original number of fish be x.After giving 2/3 of the fish, Nicholas has (1-2/3)x fish remaining.After giving 2/5 of the remaining fish, he has [tex](1-2/3)*(1-2/5)x = 30[/tex] fish left. Solve for x to find the initial number of fish.

After 4 apples were added to a sack, there were 3 times as many apples in the sack as before. How many apples were in the sack before the addition?

Answers

Hello!
So, your equation for this problem would be—
x+4=3x
To solve this equation, you need to move the variables (x) to only one side of the equation.
So, you would use the Subtraction Property of Equality.
x+4=3x
-x -x
—————
4=2x
Now, your new equation is 4=2x.
Using the Commutative Property, we can reverse this to—
2x=4
Your next step is to find X. To do this, we can divide each side by 2.
2x=4
———
2 2

____

2/2=1. 4/2=2
Thus your new equation is—

X=2.
As a conclusion, there were 2 apples in the sack before you added the extra ones.

To check this, you could do
2+4= 6
6/3= 2

There were 2 apples originally in the sack.

Hope this helped!

The number of shirts Kelly has to choose from is 2, namely Redshirt and Pink shirt. Computed using the Cartesian Product of sets.

What is the Cartesian Product of two sets?

The cartesian product of two sets A and B is a set containing ordered pairs (x, y), for every x ∈ A, and every y ∈ B.

How to solve the question?

In the question, we are informed that Kelly is picking out an outfit to wear. The organized list below represents the sample space of all possible outfits.

Redshirt – Black pants

Redshirt – White pants

Pink shirt – Black pants

Pink shirt – White pants

We are asked to find the number of different color shirts Kelly has to choose from.

Assuming the sample space to be the Cartesian Product of the set of shirts and set of pants, we can write the set of shirts as the first element of every ordered pair to get:

Set of Shirts = {Redshirt, Redshirt, Pink Shirt, Pink Shirt}.

Removing the repeating terms, we get:

Set of Shirts = {Redshirt, Pink Shirt}.

Thus, the number of shirts Kelly has to choose from is 2, namely Redshirt and Pink shirt. Computed using the Cartesian Product of sets.

Alice read a total of 36 books over 6 months. After belonging to the book club for 14 months, how many books will Alice have read in all?

Answers

Well if she read 36 books in 6 months, we can conclude that she reads 6 books per month. So if we take 6 * 14, we'll get 84.

She read 84 books in 14 months

36 books = 6 months.
Divide both sides by 6.
6 books = 1 month is Alice’s reading average.
6 books x 14 months = 84 books

Alice will have read 84 books in 14 months.

Carmen cuts a 60 inch long wire into pieces that are 3/4 inch long. How many pieces does she have?

Answers

Basically, she is dividing a 60 inch long wire into 3/4 pieces. So, what we have to do here is divide 60 by 3/4.

= 60 ÷ 3/4

Keep the first number, change the sign, and flip the fraction.

= 60 × 4/3

You can reduce the numbers by the GCF (greatest common factor) of 3.

= 20 × 4/1

After reducing 60 to 20 and 3 to 1, you are left with 20 × 4/1 or simply 20 × 4.

Multiply the numbers as usual, and you will get your product of 80.

Match the inequality to the graph of its solution.
a. n/4 ≤ -1
b. -10 ≥ -100
c. 5x ≥ 20

Answers

a. n/4 ≤ -1

Multiply both sides by 4 => n ≤ - 4, which is all the real numbers less or equal than - 4.

That in the real number line is all the numbers to the left of - 4 (including -4)

The matching graph is the B.

b. -10n ≥ -100

Divide both sides by - 10 => n ≤ 10

That is all the real numbers less or equal than 10.

In the real number line it is all the numbers to the left of 10, including 10.

So, the matching graph is the A.

c. 5x ≥ 20

Divide both sides by 5 => x ≥ 4

That is all the real numbers greater or equal to 4.

In the real number line it is all the numbers to the right of 4, including 4.

The agent withdraws 30% of his 10631.25 to pay for a trip to Montego bay, Jamaica. He hotel costs $350 per night for five nights plus an 8.5% room tax. How much does the agent have remaining

Answers

I believe the agent has $1,290.63 left.

Because... 30% of 10,631.25 is $3,189.38( the exact was 3,189.375 but I rounded up). That's how much the agent has. Since it is $350 a night, 350 x 5= $1,750.00. Then you add the 8.5% to the $1,750 and you get $1,898.75. That will be the total amount of money he will spend. So you will have to subtract $1,898.75 from $3,189.38 and the amount is $1,290.63. The remaining amount is $ 1,290.63. I hope this helps :)

Aubrey and Charlie are driving to a city that is 120 mi from their house. They have already traveled 20 mi, and they are driving at a constant rate of 50 mi/h. Complete the function that models the distance they drive as a function of time. Then complete a reasonable domain for this situation.

Answers

1. The total distance will be equal to 20 miles plus the remaining distance which would be obtained when you multiply the speed to time t. The equation would be written as follows:

120 = 20 + 50t

2. The minimum time would be 0 hours. The maximum time is when the total distance of 120 is fully covered.

t ≤ (120 - 20)/50
t ≤ 2 hours

Thus, the domain would be 0 < t ≤ 2.

The function that models the distance they drive as a function of time is 120 = 20 + 50t

The required domain must be within the range of 0 and 2 i.e. 0≤t≤2

The formula for calculating distance travelled is expressed as:

Distance = Speed × time

Given the following

Total distance = 120 miles

Distance already travelled = 20miles

If they are trying at a constant rate of 50mi/hr, the distance travelled at the time "t", this period will be 50t.

The required function that models the distance is expressed as;

120 = 20 + 50t

Hence the function that models the distance they drive as a function of time is 120 = 20 + 50t

To get a reasonable domain, we need to get the value of t as shown;

120 = 20 + 50t

120 - 20 = 50t

100 = 50t

t = 100/50

t = 2sec

Hence the required domain must be within the range of 0 and 2 i.e. 0≤t≤2
