An histogram provides a good visualization of data, however, the values of the data points are left out in an histogram

The correct responses are as follows;

1. The possible mean is given as follows;

Mean = ∑(fx)/(∑f)

Using the central values, we have;

Estimate of the Mean = (4.5×4 + 7.5×9 + 10.5×5 + 13.5×6 + 16.5×1)/(1 + 9+ 5+ 6+ 1) ≈ 10.7

2. The median is the middle value class

The total area of the histogram is given as follows

3 × (4 + 9 + 5 + 6 + 1) = 75

The middle value is located at half the total area = 75/2 = 37.5

The median class is the class of catfish with length 6 - 9 inches

3. There where 5 fishes caught that have lengths between 9 and 12 inches and there where 6 fishes caught that are 12 to 15 inches long

4. No, the longest fish caught was 18 inches long

A histogram enables a better data visualization, but that the values of the datasets in the histogram have been left out.

Following are the responses to the given points:

        Mean [tex]\bold{= \frac{\Sigma(fx)}{(\Sigma f)}}[/tex]

        We use the central values;

        Estimate of the Mean:

                   [tex]\bold{= \frac{(4.5\times 4 + 7.5 \times 9 + 10.5\times 5 + 13.5\times 6 + 16.5 \times 1)}{(1 + 9+ 5+ 6+ 1)}} \\\\ \bold{= \frac{18 + 67.5 + 52.5 + 81 + 16.5}{22}} \\\\ \bold{= \frac{235.5}{22}} \\\\ =\bold{10.704 \approx 10.7}[/tex]

        The entire histogram area is shown as follows:

          [tex]\to \bold{3 \times (4 + 9 + 5 + 6 + 1)= 3 \times (25)= 75}[/tex]

          This same average value is half the entire area [tex]\bold{= \frac{75}{2} = 37.5}[/tex]

          The average class seems to be catfish 6 - 9 inches long.

72/9=8

Each child pays 8 dollars

If only 6 kids go we multiply 8 and 6

since each of them are paying 8 dollars

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = πr² ( r is the radius )

Here diameter = 3 , then r = 3 ÷ 2 = 1.5 , then

A = π × 1.5² = 2.25π ≈ 7.1 ft² ( to the nearest tenth )

Answer:

37   9/20

Step-by-step explanation:

Answer:

[tex]{ \bf{answer \: is \: { \underline{37 \frac{9}{20} }}}}[/tex]

Step-by-step explanation:

When converting to fraction, you must get to know about the place values.

3 » tens

7 » ones

.4 » tenth

5 » hundredth

since last place value is hundredth, fraction denominator must be 100

therefore:

[tex]37.45 = \frac{3745}{100} [/tex]

then you can reduce by 5:

[tex] = \frac{3745 \div 5}{100 \div 5} \\ \\ = \frac{749}{20} [/tex]

In mixed fraction:

[tex] = 37 \frac{9}{20} [/tex]

A.)

Total Number of students = 60

Since each candidate passed in atleast one of English and Math ; the none of the students failed.

Percentage who passed :.

Mathematics only = 20%

English only = 40%

Since, no one failed ; percentage that passed both = 100% - (40+20)% = 40%

Number who passed Mathematics only :

20% × 60 = 12 students

Number that passed English only :

40% × 60 = 24 students.

Number that passed both = (40% × 60) = 24 students

Number that passed English = (Number that passed English only + Number that passed both) = 24 + 24 = 48

.Number that passed mathematics = (Number that passed Maths only + Number that passed both) = 12 + 24 = 36

2.)

Total daddy has = 50

Half given to mummy = 1/2 × 50 = 25

Amount given to houseboy = 10

Amount left = 50 - (25 + 10) = 15

Fraction of Amount left = 15/50 = 3/10

C.)

Length of cuboid = 12

Height = 8 cm

Volume of cuboid = 480

Width = w

Recall :

Volume = Length × width × height

480 = 12 × 8  × w

480 = 96w

w = 490 / 96

w = 5

Width of the cuboid = 5

The surface area of a cuboid : 2(lh + lw + hw)

Hence,

2([(12×8) + (12×5) + (8 ×5)]

2(96 + 60 + 40)

The answer is [tex]24/4=6 \hspace{0.1cm} and \hspace{0.1cm}4*6=24[/tex]. "unknown factor" pertains to finding an unknown value in a multiplication problem, while "quotients" refer to the results obtained in division operations.

Both concepts are fundamental in arithmetic and algebraic calculations.

In mathematics, "unknown factor" and "quotients" are related to multiplication and division, respectively:

1. **Unknown Factor:**

  - An "unknown factor" refers to a number or variable that you want to find or determine in a multiplication problem.

  - In the context of an equation like "a * b = c," where "a" and "b" are known values or variables, and "c" is the result of the multiplication, you might be trying to find the value of "a" or "b." The unknown factor is the value that you don't initially know, and you need to solve for it.

  - For example, if you have the equation "3 * x = 15," the unknown factor is "x," and to find its value, you would need to divide both sides of the equation by 3, yielding "x = 5."

2. **Quotients:**

  - "Quotients" is the plural form of "quotient," and it refers to the result of a division operation.

  - In division, the quotient is the number that you get when you divide one number (the dividend) by another number (the divisor).

  - For example, in the division problem "12 ÷ 4," the quotient is 3 because 12 divided by 4 equals 3. Here, 3 is the result or quotient of the division operation.

  - Quotients can be whole numbers, fractions, or decimals, depending on the numbers being divided and the division process.

Answer:

£65

Step-by-step explanation:

The original price of the table is unknown, so let x = original price of the table.

The price, x, increased by 4/5 of the price, so the increase is 4/5 x.

The total price after the increase is x + 4/5 x = 5/5 x + 4/5 x = 9/5 x.

The price after the increase is £117.

9/5 x = 117

5/9 * 9/5 x = 5/9 * 117

x = 65

Answer: £65

Answer:

£ 93.60 p

Step-by-step explanation:

I am not sure if I am fully correct but what I did , I divide 117 / 5 and then x by 4 to give me the price

(117/5 ) x 4 = £ 93.60 pence

117 / 5 =  £ 23.40 p x 4 = £ 93.60 pence

x = 4.4

Answer:

(2,4)

Step-by-step explanation:

the x values stays the same because you are reflecting over its axis. the 4 becomes positive

Step-by-step explanation:

Algebra Explanation: If something is reflected over the x axis, the x coordinate's sign will stay the same while the y coordinate sign will switch.

Using this info, the answer will be (2,4)

Geometric Explanation: Point P is in Quadrant 4. If we reflect a point about the x axis, it can only go to Quadrant 1. Quadrant 1 has a positive x and positive y. So this eliminates the first 2 options.

Reflecting across a line will align the pre image and current image with each other. This means the x coordinate and y coordinate will stay in the same place. So (2,4) is the answer.

Answer:

What is the degree of rotation that takes quadrilateral FGHI to F'G'H.

Step-by-step explanation:

The figure will have 180 degrees of rotation.

The process of changing the location of the image on the coordinate system will be known as the translation.

The angle of rotation is a unit of measurement in mathematics that expresses the angle at which a figure is rotated about a given point, frequently the center of a circle.

Given that the figure FGHI is translated to become F'G'H'I. Each point of the given diagram must be changed from (x, y) to (z) when it is rotated 180 degrees around the origin, either clockwise or counterclockwise (-x, -y)

Here the point H of the figure changes from ( -4,5) to (4,-5). It shows that the degree of rotation of the figure is 180.

Therefore, the figure will have 180 degrees of rotation.

Answer:

Step-by-step explanation:

We have

[tex]\sin A=\frac{5}{13}[/tex]

Draw a right triangle where the side in front of the angle A is 5 and the hypothenuse is 13. Hence the length of the other angle is [tex]\sqrt{13^2-5^2}=12[/tex].

It follows that

[tex]\cos A=\frac{12}{13}[/tex] and [tex]\tan A= \frac{5}{12}.[/tex]

Subtitute this we obtain

[tex]5\sin A-\frac{2\cos A}{\tan A}=5\cdot \frac{5}{13}-\frac{12/13}{5/12}[/tex]

which is equal to

[tex]\frac{25}{13}-\frac{144}{65}=\frac{125-144}{165}=-\frac{19}{165}.[/tex]

[tex]2-\frac{1}{8}y-2=11+\frac{7}{8}y-2[/tex]

[tex]-\frac{1}{8}y=\frac{7}{8}y+9[/tex]

➠ Subtract 7/8y  from both sides:-

[tex]-\frac{1}{8}y-\frac{7}{8}y=\frac{7}{8}y+9-\frac{7}{8}y[/tex]
