Step-by-step explanation:

To find the surface area of the prism, we find the area of each similar faces and multiply by 2 and then add all together

Area of square faces

[tex]2(4\times 4)=16m^2[/tex]

Area of parallelogram faces

[tex]=2bh[/tex]

[tex]=2(2\times 4)=16m^2[/tex]

Area of the rectangular faces;

[tex]=2(4\times 2.5)=20m^2[/tex]

The total surface area of the prism is 20+16+32=68 square meters

Answer:

Step-by-step explanation:

Find the median and the upper/lower quartiles

Rearrange the data in ascending order

33, 36, 37, 38, 41, 42, 46, 49, 50, 50, 51, 52, 53, 54

The median is the middle value of the data or if there is no exact value at the middle then it is the average of the 2 values either side of the middle

Here the median is between 46 and 49

median = [tex]\frac{46+49}{2}[/tex] = 47.5

The upper quartile is the middle value of the data to the right of the median

[tex]Q_{3}[/tex] = 51

The lower quartile is the middle value of the data to the left of the median

[tex]Q_{1}[/tex] = 38

The minimum value = 33

The maximum value = 54

The lower quartile is the left side of the box plot

The upper quartile is the right side of the box plot

The median is located inside the box plot

The corresponding box plot is B

Answer:

C. F(x) = (x - 4)^2

Step-by-step explanation:

f(x) = (x - h)^2 is a parabola that opens up and has the line x = h as the vertical axis.

Here, the vertical axis is x = 4, so h must be 4.

The answer is: C. F(x) = (x - 4)^2

The solution is, Mean Absolute Deviation = 2.2222

The next three procedures are necessary to calculate the mean absolute deviation.

By adding up all the observations and dividing by the sample size, you can determine the sample average.

Discover the total deviation from the mean of each data point. When negative signals appear, ignore them and instead deduct the observed values from the mean.

Determine the absolute deviations' average. Divide the total of the values from step #2 by the sample size.

here, we have,

Input Data:

Data set = 1, 2, 3, 4, 5, 6, 7, 8, 9

Total number of elements = 9

Objective:

Find what is mean absolute for given input data?

Solution:

X mean = (1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9)/9

= 45/9

X mean = 5

MAD = (1 - 5) + (2 - 5) + (3 - 5) + (4 - 5) + (5 - 5) + (6 - 5) + (7 - 5) + (8 - 5) + (9 - 5)9 = (4) + (3) + (2) + (1) + (0) + (1) + (2) + (3) + (4)9

#SPJ2

Answer:

314 units²

Step-by-step explanation:

Centre of the circle = (0, 0)

Another point on the circle = (-6, -8)

[tex]\text {Radius = }\sqrt{(0 - (-6))^2 + (0- (-8))^2}[/tex]

[tex]\text {Radius = }\sqrt{6^2 + 8^2}[/tex]

[tex]\text {Radius = }\sqrt{100}[/tex]

[tex]\text {Radius = }10[/tex]

Area = π (10)² = 100π = 314 units²

Final answer:

The area of the circle is found by first calculating the radius using the distance formula, which is determined to be 10 units. Then, the area formula πr² is used to find that the area of the circle is 100π square units.

Explanation:

To find the area of the circle centered at the origin containing the point (-6, -8), we first need to determine the radius of the circle. The radius can be found using the distance formula for a point from the origin, which is √((-6)²+ (-8)²). After calculating the radius, we use the formula for the area of a circle, which is πr^2, to find the circle's area.

The distance from the origin to the point (-6, -8) is the radius (r) of the circle: r = √((-6)² + (-8)²) = √(36 + 64) = √100 = 10.

Now that we have the radius, we can calculate the area (A): A = πr² = π(10)² = 100π square units.

Answer:

Area of 81 sq in: 40.2

Perimeter of 36 in : 9

Step-by-step explanation:

Hope I'm right! :)

Answer:

9 inches

Step-by-step explanation:

A square has an area of 81 in^2

A = s^2

81 = s^2

Take the square root of each side

sqrt(81) = sqrt(s^2)

9 = s

The side length is 9 inches

A square has a perimeter of 36 in

P = 4s

36 = 4s

Divide each side by 4

36/4 = 4s/4

9 = s

Each side is 9 inches

Answer:

61

Step-by-step explanation:

The first thing that you want to do is distance formula

[tex]d=(x_{2}-x_{1} )^{2} + (y_{2}-y_{1} )^{2}[/tex]

I'm going to make the start of the line at (1,1) and that means that the end of the line is at (7,6). Now, you plug these numbers into the formula.

[tex]d=(7-1 )^{2} + (6-1 )^{2}[/tex]

Then you slove

[tex]d=(6 )^{2} + (5 )^{2[/tex]

[tex]d=36 + 25[/tex]

[tex]d=61[/tex]

Distance formula: d =√(x2-x1^2 +y2-y1^2)

Find the points of the line: (2,2) and (8, 7)

Length = √((8-2)^2 + (7-2)^2)

Length = √(6^2 + 5^2)

Length = √(36+25)

Length = √61 ( exact answer) or as a decimal: 7.81

Answer:

The plane should pass through the central axis, along the vertical diagonals of the cube, in order to produce a cross section that is a regular hexagon.

Step-by-step explanation:

The plane should pass through the central axis, along the vertical diagonals of the cube, in order to produce a cross section that is a regular hexagon.

Please see the image attached for better visualization.

To produce a regular hexagon as a cross section of a cube, the plane should pass through the cube's vertices and form an equilateral triangle with the three edges it intersects.

In order to produce a regular hexagon as a cross section of a cube, the plane should pass through the cube's vertices. The three edges that the plane passes through should form an equilateral triangle on the face of the cube. This is because a regular hexagon can be formed by placing equilateral triangles side by side.

Plug in 6 for d.

[tex]P=\frac{1}{2}\pi*6+6[/tex]

Answer:

Step-by-step explanation:

The perimeter = pi * d + d

d = 6 miles

The perimeter = pi*6 + 6       This is one possible answer

perimeter = 6*3.14 + 6

Answer:

(1/3)³c = 5

(1/27)c = 5

c = 5 × 27 = 135 cubes

The Main Answer is 135. It takes [tex]135[/tex] of the [tex]1/3[/tex] unit cubes to fill the rectangular prism.

To find out how many [tex]1/3[/tex] unit cubes it takes to fill the rectangular prism with a volume of [tex]5[/tex] cubic units, we need to divide the volume of the prism by the volume of each individual cube.

The volume of the rectangular prism is given as [tex]5[/tex] cubic units. Since the prism is a rectangular shape, we can calculate its volume using the formula:

[tex]Volume of prism=length*width*height[/tex]

Given that the side length of each cube is [tex]1/3[/tex] unit, the volume of each cube is:

[tex]Volume of cube=(side length)^{3} =(1/3)^{3}=1/27 cubic[/tex]

Now, to find out how many cubes are needed to fill the prism, we divide the volume of the prism by the volume of each cube:

[tex]Number of cubes=Volume of prism/Volume of cube \\Number of cubes=5/(1/27)\\Number of cubes=5*27\\Number of cubes=135[/tex]

So, it takes [tex]135[/tex] of the [tex]1/3[/tex] unit cubes to fill the rectangular prism.

Answer:

R = 50

Step-by-step explanation:

The sum of the angles of a triangle equal 180 degrees

S + R + Q = 180

x+70 + x+ 20 + x = 180

Combine like terms

3x +90 =180

Subtract 90 from each side

3x+90-90 = 180-90

3x= 90

Divide by 3

3x/3= 90/3

x = 30

We want to find angle R

R = x+20

R = 30+20

R = 50

Step-by-step explanation:

To find this, we need to understand the combination formula.

If we have n items and we want to choose r at a time, we use the formula:

Where n! means n(n-1)(n-2)....

So we want 9C3, plugging them into the formula and doing some arithmetic, we have:

[tex]nCr=\frac{n!}{(n-r)!*r!}\\9C3=\frac{9!}{(9-3)!*3!}\\=\frac{9!}{6!*3!}\\=\frac{9*8*7*6!}{6!*3*2*1}\\=\frac{9*8*7}{3*2*1}\\=84[/tex]

So, there can be 84 combinations possible.

As per the shown graph, the coordinates of the vertices:

A(0,2)

B(2,4)

C(3,0)

We observe that the y-axis is the vertical line passing through x = 0, and the x-axis is the horizontal line passing through y = 0.

By analyzing the positions of the vertices, we can see that the triangle has rotational symmetry of 180 degrees around points (1, 2) and reflectional symmetry across both the x-axis and the y-axis.
