The box plot will have its left tail longer than the right tail becuase a few exceptionally low prices make the distribution skewed to the left.                                              

Step-by-step explanation:

As seen in the attached file, the box plot has its left tail longer than the right tail because of the exceptionally low prices that is :$2

Firstly arranging the data in increasing order:

$2,$2,$25,$25,$26,$26,$27,$27,$28,$28,$30

Median of the data = 26 (since there are odd numbers)

Lower quartile (Q1) = 25

Upper quartile (Q2) = 26

By plotting the box plot we conclude that the left tail is longer than the right tail.

Step-by-step explanation:

Since Farmer Tim has one of each coin, 50+20+10+5=85 cents are accounted for, leaving 395 - 85 = 310 cents for the remaining coins. We can try minimizing the number of coins that add up to 310 cents by using as many large denominations as possible.

The largest denomination is 50 cents, so we can take six 50 cent coins, which add up to 6 times 50 = 300 cents. We then can take one 10 cent coin. Thus, we have a combination of seven coins that up to 310 cents.

Therefore, the smallest number of coins that Farmer Tim could have is 4 + 7 = 11.

Answer:

A factor of 24 is a number that can be multilied by another number (normally whole (not fraction or decimal) numbers) so a factor must be less than the number any multiple of 2 greater than 24 will work so just any even number greater than 24 exg 26,28,30,32,34,36,38,40,42,44,46,48,50,52,54,56,58,60, and so on.

Step-by-step explanation:

Not all multiples of a number are its factors. In the case of the number 24, only the multiples that can divide evenly into 24, which include 1, 2, 3, 4, 6, 8, 12, and 24, can be considered its factors. Higher multiples like 48, 72 or 96 are not factors as they do not divide into 24.

In mathematics, the multiples of a number are obtained by multiplying that number by any integer. The factors of a number, on the other hand, are the numbers that you can evenly divide into that number. Therefore, for the number 24, its multiples include 24, 48, 72, 96, and so on.

However, not all multiples of 24 are factors of 24. A factor must divide into 24 with no remainder, which isn't the case with greater multiples of 24. For instance, 48, 72, 96 etc. are multiples of 24, but they are not factors of 24 because they cannot divide evenly into 24.

rational number: any number that can be written as a fraction of integers

Answer: B: integer and rational number

Answer:

B and C.

Step-by-step explanation:

-20 is a negative integer.

It is also rational.

In a parallelogram, opposite angles are the same.

Because you are given angle C is 70 degrees, angle R is also 70 degrees.

An exterior angle of a triangle is equal to the sum of the two opposite inside angles.

Angle KSO is an exterior angle to the triangle made from ORS,

So angle KSO would equal the sum of angle O and angle R.

Angle KSO = 65 + 70 = 135 degrees.

To find the perpendicular slope, we simply flip the fraction (aka reciprocal) and flip the sign (go from positive to negative, or vice versa)

So for problem 1a) we flip the fraction to go from 4/3 to 3/4. Then we flip the sign to go from +3/4 to -3/4. The final answer to problem 1a) is -3/4

The answer to problem 1b) is 7/3 following the same basic steps: -3/7 ---> -7/3 ---> 7/3

The answer to problem 1c) is -1/4. You can think of 4 as 4/1 which flips to 1/4 and it becomes -1/4

Answer:

Step-by-step explanation:

First find 2 points on the line.  To do this you will need to substitute numbers in for x and y.  Do this by first putting 0 in for x to find the value of y:

9(0) + 4y = -36

0 + 4y = -36       =  4y = -36   =        y = -36 ÷ 4 = -9     y= -9

(0,-9)

Now that we have that point substitute 0 in for y.

9x + 4(0) = -36

9x + 0 = -36   =    9x = -36     =    x = -36  ÷ 9    x = -4

(-4,0)

After you have your two points decide which on you want to be (x1,y1) and which you want to be (x2,y2).  It doesn't matter which one you choose.  You will then plug in your numbers into the slope formula:

       y2 - y1           -9 - 0         -9           The slope is - 9/4

       x2 - x1            0 - 4          -4

Answer:

$55.20

Step-by-step explanation:

What is the brokerage fee

.15 * 48 = 7.2

The total cost of his ticket is the price of the ticket plus the brokerage fee

total cost = 48 + 7.2

               = $55.20

Marcus had to pay a total of $55.20 for the concert ticket, which includes the 15% brokerage fee on top of the original ticket price.

Marcus bought a concert ticket for $48. The online ticket broker charged a 15% brokerage fee on top of the ticket price. To calculate the total amount Marcus had to pay, we first need to calculate the brokerage fee. The brokerage fee is found by multiplying the ticket's price by the brokerage fee rate. So, $48 multiplied by 15% (or 0.15) gives us the brokerage fee of $7.20. This brokerage fee is then added back to the original ticket price, so Marcus paid a total of $48 + $7.20 = $55.20 for the concert ticket.

Step-by-step explanation:

Answer:

x=15

Step-by-step explanation:

Lets start solving the equation line by line,

2/5(5+x)=8

For solving such type of question one must know the BODMAS Rule.

Where,

B= Bracket  

O=Orders

D=Division

M=Multiplication

A=Addition

S=Subtraction

and its very important to remember the priority of each operation, as you need to solve it as per their Priorities.

Bracket first, Orders second, Division and so on....

So now lets start with the given equation,

2/5(5+x)=8

As per the BODMAS we have to first start with brackets,

2/5(5+x)=8

2/5*5+2/5*x=8 First Step

2+2/5*x=8

2/5*x=8-2

2/5*x=6

2x=30

so x=15.

This is a very common Traditional Method  to solve such problems but their are other ways too.

Lets see one by one how NIco, Erik, Raj sandra and Aditi is trying to solve this question by their methods.

Lets analyze the method used by Nico first,

Nico has smartly multiplied both the sides of the equation with 5/2 so that the problem becomes easy to solve in further steps,

2/5(5+x)=8

5/2*2/5(5+x)=8*5/2

5+x=20

so x=15.

smart answer in a few steps.

Now let's analyze the answer by  Aditi,

2/5(5+x)=8

5/2*(5)+5/2=(5/2)8

The second step of Aditi is incorrect as it doesn't make any sense.

Now lets analyze the answer by Erik,

2/5(5+x)=8

2/5(5+x)-5=8-5

this will also yields a correct answer but subtracting 5 from both side doesn't seems to be a optimum way to solve and it will add more steps before getting the answer.

Raj has again using a smart way to solve the equation,

2/5(5+x)=8

1/2*2/5(5+x)=8*1/2

This will also gives correct answer in a few steps.

Sandra is using a traditional way to solve the question and it will also give correct result.

So, we can say that except Aditi all will get the correct answer.

and if we compare then Nico and Raj will get the answer in few steps.

I hope this will help you.

Answer:

The equation of the line would be y = 5/4x - 4

Step-by-step explanation:

To find the equation of any line, start by finding the slope using the slope formula.

m(slope) = (y2 - y1)/(x2 - x1)

m = (-4 - 1)/(0 - 4)

m = -5/-4

m = 5/4

Now that we have the slope, use that and either point to get the equation of the line

y - y1 = m(x - x1)

y + 4 = 5/4(x - 0)

y + 4 = 5/4x

y = 5/4x - 4

The equation of the line would be y = (5/4) x - 4. Hence, option B is correct.

An equation is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

To find the equation of any line, start by finding the slope using the slope formula.

m(slope) = (y₂ - y₁)/(x₂ - x₁)

m = (-4 - 1)/(0 - 4)

m = -5/-4

m = 5/4

Now that we have the slope, use that and either point to get the equation of the line.

y - y₁ = m(x - x1)

y + 4 = 5/4(x - 0)

y + 4 = 5/4x

y = 5/4x - 4

Hence, option B is correct.

25(x-y) simplified using the distributive property gives us 25x - 25y.

WE are given the expression as 25x-25y

WE know that distributive property states that an expression of the form A(B + C) can be solved by a multiplication over addition operation that is

A(B + C) = AB + AC

To use the distributive property to simplify 25(x-y), we need to distribute the 25 to both x and y separately.

So,

25(x-y) = 25(x) - 25(y)

= 25x - 25y

Therefore, 25(x-y) simplified using the distributive property gives us 25x - 25y.

Final answer:

The expression 25(x-y) is simplified using the distributive property by multiplying 25 by each term inside the parentheses, resulting in 25x - 25y.

Explanation:

To use the distributive property to simplify the expression 25(x-y), you should multiply each term inside the parentheses by 25.

This is what it looks like when we apply the distributive property:

25 × (-y) = -25y

So, the simplified expression is 25x - 25y.

When we evaluate expressions, we are typically trying to express them in a way that shows the multiple or product terms explicitly. This process is like reversing distributive law and turning it back into factors (multiples). Here, the distributive law helps us see that the expressions 25x and -25y, when combined, produce the same value as the original expression 25(x-y).

The simplified expression for (m+13)-(p+25) is m - p - 12.

To simplify the expression (m+13)-(p+25), we can distribute the negative sign to both terms inside the parentheses:

[tex]\[m + 13 - p - 25.\][/tex]

Next, combine like terms by grouping the variables (m and -p) and the constants (13 and -25):

[tex]\[m - p + 13 - 25.\][/tex]

Now, simplify the constants:

[tex]\[m - p - 12.\][/tex]

So, the final answer is m - p - 12. This expression represents the simplified form of the given algebraic expression.

In the original expression, (m+13)-(p+25), we subtracted the entire quantity (p+25) from (m+13). Distributing the negative sign, we subtracted p and 25 individually. Combining like terms involved combining the variables (m - p) and constants (13 - 25). The final result is m - p - 12, where m and p are coefficients of the respective variables, and 12 is the simplified constant term.

In summary, the expression (m+13)-(p+25) simplifies to m - p - 12 by applying the principles of combining like terms and distributing the negative sign. This simplified form is a more concise representation of the original expression.

Answer:

25/w = l

Step-by-step explanation:

We know that the formula for the area of a rectangle is

A = l*w

We know the area is 25

Substituting this into the equation

25 = l*w

We are to solve for l, by dividing each side by w

25/w = lw/w

25/w = l

To find the length (L) of a rectangle when the area (A) is 25 square inches, you use the formula L = A/W, substituting A with 25 and W with the given width.

To solve for the length (L) of a rectangle with a known area (A), you first need the formula for a rectangle's area, which is A = L × W, where L is the length and W is the width of the rectangle. Given that the area (A) is 25 square inches and the area formula has been incorrectly stated as A = 2LW, we should correct it to A = LW.

If you have a specific width (W), you can rearrange the formula to solve for L by dividing both sides by W, resulting in L = A/W.

Using an example, if we know the width (W) is 5 inches, we could substitute into the formula:

L = A/W

L = 25 in2/5 in = 5 in

Therefore, the length (L) of the rectangle would be 5 inches.
