Answer: D. The Median and they should predict 58.5 inches.

Step-by-step explanation: Before we start, we want to use median. This is because there is an outlier, 72, and that would mess up the mean by a small yet noticeable margin.

Since the median picks both numbers 58.5 and 58.5, that means that the answer will be D. The Median and they should predict 58.5 inches.

Answer:

D The median and they should predict 58.5

Step-by-step explanation:

If you count from the outsides and go to the inside with a pencil or you're fingers then you get 58.5 :D

Step-by-step explanation:

The given circle has diameter  [tex]8\frac{3}{5}[/tex].

We can write as a decimal to obtain;

[tex]8\frac{3}{5}=8.6[/tex]

On the number line 8.6 is between 8 and 9 but closer to 9.

From the graph the correct answer is D

4(2x-5) is the answer

answer: 4(2x - 5)

explanation: if you don’t know how to factor gcf, look it up. But you need to find the gcf of 8 and 20 which is 4. Then you just get your answer. Sorry this is hard to explain but a tip is to distribute and check to see that it matches the original problem to find out if your answer is right. I will do that for this. 4(2x - 5) I use distributive property here meaning I distribute the 4 to both terms. 4 times 2x is 8x. 4 times negative 5 is negative 20. That leaves me with the original equation 8x - 20 so the answer is correct.

The equation that represents an inverse variation with a constant of 56 is:

             Option: D

         D.   [tex]\dfrac{xy}{2}=28[/tex]                  

Inverse Variation--

It is a relationship between two variables such that it is given in the form that:

If x and y are two variables then they are said to be in inverse variation if there exist  a constant k such that:

[tex]y=\dfrac{k}{x}[/tex]

i.e.

[tex]xy=k[/tex]

Here the constant of variation is 56

i.e. k=56

Hence, we have:

[tex]xy=56\\\\i.e.\\\\xy=28\times 2\\\\i.e.\\\\\dfrac{xy}{2}=28[/tex]

              Hence, option: D is the correct answer.

Answer: 11

Steps

1. 100-15=85

2. 85/8=10.625

3. 10.625 rounds up to 11

Final answer:

Terry needs to buy at least 11 boxes of candles to meet her requirement of having at least 100 candles, as she must purchase whole boxes and not a fraction of a box.

Explanation:

Terry has 15 candles and needs a total of at least 100 candles. To find the least number of boxes she needs to buy, we should first find out how many more candles are required to reach a minimum of 100 candles:

100 - 15 = 85 candles needed.

Next, we calculate how many boxes of 8 candles this equates to by dividing the number needed by the number of candles per box:

85 ÷ 8 = 10.625.

Since Terry cannot buy a fraction of a box, we round up to the nearest whole number, which gives us 11 boxes.

Therefore, the least number of boxes Terry needs to buy is 11 to acquire at least 100 candles.

Answer:

The answer in one common tangent only ⇒ answer (B)

Step-by-step explanation:

∵ The two circles touch internally in a common point

* At this point we can draw only one tangent

∵ This point is common in the two circles

∴ The tangent will be common for the two circles

∴ There is only one common tangent can be draw passing

   through the common point which the two circles

   touch each other on it

∴ The answer is (B)

Answer:

D - 56.6 MPH is the faster

Step-by-step explanation:

Find the unit rate by dividing the miles by hours

A. 589/11 = 53.55 MPH

B. 360/7 = 51.43 MPH

C. 111/2 = 55.5 MPH

D. 283/5 = 56.6 MPH

After calculating the speed for each option by dividing the distance by time, option D is found to be the fastest with a speed of 56.6 mph.

To find out which rate is the fastest, we need to calculate the speed for each option by dividing the distance by the time.

The speed is the distance traveled per unit of time, typically expressed in miles per hour (mph).

Comparing the calculated speeds, option D is the fastest with a speed of 56.6 mph.

A denominator is the number that a fraction is being divided by, or the number below the line is a fraction. In this case the denominator is 7.

Answer:

22/45

Step-by-step explanation:

Let A be the event of drawing a multiple of 2,  

So,  

p(A)=  23/45

Now, let A' be the opposite(complementary) event which means not drawing a multiple of 2

From the properties of probability, the sum of an event’s probability and its opposite(complementary) event’s probability is equal to 1.

p(A)+p(A')=1

We have to find the probability of not drawing a multiple of two i.e. p(A')

p(A')=1-p(A)

=1 - 23/45

=  (45-23)/45

=22/45

So the probability of not drawing a multiple of 2 from the hat is 22/45.

Final answer:

The probability of not drawing a multiple of two from the numbers 30 to 74, given the probability of drawing a multiple of two is 23/45, is computed by subtracting 23/45 from 1, resulting in a probability of 22/45.

Explanation:

The probability of not drawing a multiple of two is simply calculated by subtracting the probability of drawing a multiple of two from 1, as these probabilities are complementary.

Given that the probability of drawing a multiple of 2 is 23/45, we can find the probability of not drawing a multiple of two by doing the following:

1 - (probability of drawing a multiple of 2) = 1 - (23/45) = 22/45.

Therefore, the probability of not drawing a multiple of two is 22/45.

A might be the answer because 20%of 24 = 4.8 and 24×0.20 give you 4.8

Answer: The correct answer is H.

Step-by-step explanation: The first step is to calculate how much he is going to pay 28% on. The difference between $3,775 and $3,523 = $252.

The formula to calculate his total taxes = .28 x $252 + $699.65.

$70.56 + $699.65 = $770.21, which is the total federal taxes that he needs to pay.

Next, to determine the amount he will receive you need to subtract the taxes from his gross income. $3,775 - $769.65 = $3,004.79 Net Income

Step-by-step explanation:

The 7th term in the geometric sequence with a first term of 5 and a common ratio of 2 is found using the formula for the nth term of a geometric sequence. The 7th term is calculated to be 320.

The student has asked to determine the 7th term in a geometric sequence whose first term is 5 and whose common ratio is 2. To find this, we can use the formula for the nth term of a geometric sequence, which is an = a1  times rⁿ⁻¹, where a1 is the first term, r is the common ratio, and n is the term number.

To find the 7th term:

Identify that the first term (a1) is 5

The common ratio (r) is 2

Insert these values into the formula to get a7 = 5  times 2⁷⁻¹

Calculate the exponent: 2⁶ = 64

Multiply by the first term: 5  times 64 = 320

Therefore, the 7th term in the geometric sequence is 320.

Multiply the length times width:

30 1/2 x 9 1/3= 284.6

Hence, the area of the rectangular space is:

                          284.6667 square yards.

It is given that the length(l) of the rectangular space is: [tex]30\frac{1}{2}\ yard[/tex] .

which in improper fraction is: [tex]\dfrac{61}{2}\ yard[/tex]

Similarly, the width(b) of the rectangular space is: [tex]9\frac{1}{3}\ yard[/tex]

which in improper fraction is: [tex]\dfrac{28}{3}\ yard[/tex]

As we know that the area of the rectangular space is calculated as:

[tex]Area=l\times b\\\\\\Area=\dfrac{61}{2}\times \dfrac{28}{3}\ \text{square\ yards}\\\\\\Area=284.6667\ \text{square\ yards}[/tex]

 Hence, Area is: 284.6667 square yards.

The equation of the graph is y= -(x+3)^2 +1

Choice A is the correct answer

The equation of the given graph is:

We know that the general equation of a downward parabola with vertex at (h,k) is given by the formula:

      [tex]y=a(x-h)^2+k[/tex]

where a<0

Here in each of the options we have a= 1 or -1

but as a has to be less than 1 this means that a= -1

Also, we have: (h,k)= (3,1)

i.e. h=3 and k=1

Hence, putting the values of h,k and a in the general equation we get:

      Hence, the equation of parabola is:

       [tex]y=-(x-3)^2+1[/tex]

Answer:

55 pages

Step-by-step explanation:

Knowing that the book holds 600 cards and 6 cards/page, we can tell that there are 100 pages.

From that, we know that 45% are empty, which means 55% of all of the pages have cards.

55% of 100 is 55. Therefore, 55 pages have baseball cards.

Final answer:

To find out how many pages of Thomas's album are filled with baseball cards, we first calculate the number of filled card slots and then divide by the number of slots per page, resulting in 55 filled pages.

Explanation:

Thomas has an album that holds 600 baseball cards, and each page of the album holds 6 cards. If 45% of the album is empty, we first calculate how many cards are in the filled portion of the album, and then determine how many pages are filled with baseball cards.

First, find 45% of 600 to determine the number of empty slots: 0.45 × 600 = 270. Therefore, there are 270 empty slots for baseball cards. To find the number of filled slots, subtract this number from the total capacity: 600 - 270 = 330 filled slots.

Since each page holds 6 cards, to find out how many pages are filled, divide the number of filled slots by the number of slots per page: 330 ÷ 6 = 55. Therefore, Thomas has filled 55 pages with baseball cards.

Answer: is there a picture or something like that?

Step-by-step explanation:  

Answer:

For the (), it is 32. r = 13.

Step-by-step explanation:

32 - 13 = 19.

In order to match each of the pairs you need to divide the numerator by the denominator to make it into a decimal.

Below are the pairs:

21/25 = 84%

13/20 = 65%

2/5 = 40%

3/4 = 75%

3/5 = 60%

21/25 = 84%

13/20 = 65%

2/5 = 40%

3/4 = 75%

3/5 = 60%

4 --

  11

Step-by-step explanation:

The gear ratio for the original gear system was 4/22. To get the 22 inch wheel to 26 inches, you have to multiply it by 26/22, so to keep the same ratio, you will also need to multiply 4 by 26/22. You get 104/22, which simplifies to 52/11 which simplified further to 4+8/11. You can check your answer by comparing the original ratio to the new ratio.

Using the principle of constant proportion, the new gear size for a bike with a 26-inch wheel while maintaining the original gear-to-wheel diameter ratio is approximately 4.73 inches.

The student asked about the gear size for a bike with a 26-inch wheel if the existing bike uses a 4-inch gear with a 22-inch wheel diameter, and the ratio of the gear size to the wheel diameter is constant.

To find the new gear size, we set up a proportion using the given gear and wheel sizes:

Cross-multiplying to solve for x gives us:

4 inches * 26 inches = 22 inches * x inches

104 = 22x

x = 104 / 22

x = 4.727272... inches

So, the new gear size would be approximately 4.73 inches if we maintain the same ratio for a bike with a 26-inch wheel.

Sorry, I messed up. So I changed it.

The system of linear equations, \(x + 2y = 4\) and \(-2x + 5y = 10\), was solved graphically. The lines intersect at (2, 1), yielding the solution \(x = 2\) and \(y = 1\).

To solve the system of linear equations graphically, we'll plot the lines corresponding to each equation and find their point of intersection, which represents the solution to the system.

Let's rearrange the equations to be in slope-intercept form (\(y = mx + b\)) for ease of graphing:

a. \(x + 2y = 4\)

  \[ 2y = -x + 4 \]

  \[ y = -\frac{1}{2}x + 2 \]

b. \(-2x + 5y = 10\)

  \[ 5y = 2x + 10 \]

  \[ y = \frac{2}{5}x + 2 \]

Now, we'll plot these lines on the graph:

The graph shows that the two lines intersect at the point \((2, 1)\). Therefore, the solution to the system of linear equations is \(x = 2\) and \(y = 1\).
