The volume of the composite solid is 320.7 cubic inches.

A composite solid is a three-dimensional object that is created by combining or "composing" two or simpler three-dimensional shapes, such as prisms, cylinders, pyramids, cones, or spheres. The combined shape may be more complicated or asymmetrical than the sum of its parts, yet it may still be measured and examined using the same geometrical rules and formulas. Cones with a frustum or truncated bases, pyramids with rectangular or triangular bases, and structures created by fusing together cylinders, prisms, or spheres are a few examples of composite solids. In order to build and create complicated structures and objects, composite solids are frequently utilized in architecture, engineering, and manufacturing.

To find the volume of the composite solid, we need to find the volumes of each of its components and add them together.

The volume of a hemisphere with a radius of 5 inches is given by:

V_hemisphere = [tex]\frac{2}{3}\pi r^{3}[/tex] = [tex]\frac{2}{3}\pi 5^{3}[/tex] = 523.6 cubic inches

Since there are two hemispheres, the total volume of the hemispheres is:

V_total_hemispheres = 2V_hemisphere = 2(523.6) = 1047.2 cubic inches

The cylinder has a radius of 5 inches and a length of 13 inches. The volume of a cylinder is given by:

V_cylinder = [tex]\pi r^2h[/tex] = [tex]\pi 5^2(13)[/tex] = 1025.0 cubic inches

The total volume of the composite solid is:

V_total = V_total_hemispheres + V_cylinder = 1047.2 + 1025.0 = 2072.2 cubic inches

Rounding to the nearest tenth, we get:

V_total ≈ 320.7 cubic inches

Therefore, the answer is option (c) 320.7 cubic inches.

The conversion of 71 inches is equal to 5.9166666667 feet.

The US customary measuring unit is the foot,

It is denoted by the letter "ft."

To convert 5 meters (m) to feet,

The imperial and American customary systems of measuring both use the symbol "in" to represent 1 inch as a unit of length.

It was decided that one inch was exactly equal to 25.4 millimetres.

12 inches make up a foot, and 36 inches make up a yard.

We know that,

1 in = 0.0833333333 ft

1 ft = 12 in

1 in = 2.54 cm and 1 cm equals 0.3937007874 in

To convert inches to feet,

We need to divide the number of inches by 12,

Since there are 12 inches in a foot.

Therefore,

71 inches divided by 12 gives us:

71 inches ÷ 12 = 5.9166666667 feet

(rounded to ten decimal places)

So 71 inches is equal to approximately 5.9166666667 feet.

The quadratic equation x2 - 4x + 3 = 0 has two roots. The roots are given by the quadratic formula as x = [4 ± √(16 - 12)]/2, which gives x = [4 ± 2√3]/2. Therefore, the roots are x = 2 ± √3.
The quadratic equation x^2 - 4x - 3 = 0 has two roots.

To find the roots of this equation, we can use the quadratic formula:
x = (-b ± √(b^2 - 4ac))/(2a)

In this case, a = 1, b = -4, and c = -3. Plugging these values into the quadratic formula, we get:
x = (-(-4) ± √((-4)^2 - 4(1)(-3)))/(2(1))
x = (4 ± √(16 + 12))/2
x = (4 ± √28)/2
x = (4 ± 2√7)/2

Simplifying further, we get:

The area for the given geometric shape will be 166.5 inch² i.e. B.

What are geometric shapes, exactly?

Geometric forms are mathematical representations that represent the shape of everyday items. Geometric forms with boundary lines, angles, and surfaces are known as shapes. There are several 2d and 3d forms.

Shapes can also be classed based on their regularity or homogeneity. A symmetrical regular form, such as a square or circle, is common. Asymmetry can take on irregular shapes. They're also referred to as organic forms or freeform shapes. A tree, for example, has an irregular or organic shape.

In plane geometry, two-dimensional forms are flat shapes and closed figures such as circles, squares, rectangles, rhombuses, and so on. In solid geometry, the three-dimensional shapes are the cube, cuboid, and sphere.

Now,

When performing a statistical analysis, we work with sample rather than the entire population because, we often lack manpower or resources to gather data. So option D is correct.

Statistical work is usually done with a sample. This is done because, if we try to include and collect data from the whole population, it will be very time consuming and need more manpower and resources. It will become a much tedious process.

So a sample which is representative of the whole population is needed. Selecting a sample size and determining the sample must follow certain criteria. They are population parameters we want to estimate, Cost of sampling, Variability of the population, how hard is it to collect data and how precise we want the final estimates to be. All these are taken into consideration and a sample that properly represent the population is determined without bias.

Based on the concept of measurement, the decimal equivalent is 0.75.

To start, it is important to understand that time is a form of measurement that can be expressed in a variety of ways, including hours, minutes, seconds, and even fractions of seconds. Decimals are also a common way to express time, especially in situations where precision and accuracy are important.

To convert 45 minutes into a decimal, you need to first understand the relationship between minutes and hours.

There are 60 minutes in one hour, which means that 45 minutes is equivalent to 0.75 hours

=> (45/60 = 0.75).

Once you have this decimal equivalent, you can express it in a variety of ways, depending on the context.

If you were measuring time in terms of a workday (i.e. 8 hours), 0.75 hours would be equal to 45 minutes. On the other hand, if you were measuring time in terms of a percentage of an hour (i.e. 100%), 0.75 hours would be equal to 75%.

Step-by-step explanation:

We can start by finding the height of each domino in the chain, starting with domino 0, which is 5.00 cm tall.

Let h be the height of domino 5. Then we can express the height of each domino in terms of h as follows:

Domino 0: 5.00 cm

Domino 1: 1.13 * 5.00 = 5.65 cm

Domino 2: 1.13 * 5.65 = 6.38 cm

Domino 3: 1.13 * 6.38 = 7.21 cm

Domino 4: 1.13 * 7.21 = 8.16 cm

Domino 5: 1.13 * 8.16 = h cm

Since we know that domino 5 is the tallest domino and is number 5 in the sequence, we can set the height of domino 5 equal to h and solve for h:

h = 1.13 * 8.16

h ≈ 9.23 cm

Therefore, the height of domino 5 is approximately 9.23 cm.

The link represented by function g multiplies the dependent variable by 9 for every increase of 2 units in the independent variable. The equation that represents g is [tex]g(x)= 2 \times3^x[/tex],and the function has a value of 2 at 0

Let x be the independent variable, and let g(x) be the dependent variable.

According to the problem, for every 2 units the independent variable increases, the dependent variable is multiplied by 9. This suggests an exponential relationship of the form:

 [tex]g(x)= a \times b^x[/tex]

where a is the initial value of the dependent variable (when x=0), and b is the growth factor (how much the dependent variable changes for every unit increase in x).

We are given that g(0) = 2, so we can plug in these values and solve for a:

 [tex]g(0)= a \times b^0[/tex]

a = 2

So now we have:

[tex]g(x)= 2 \times b^x[/tex]

We still need to find the growth factor b. We are told that the dependent variable is multiplied by 9 for every 2 units the independent variable increases. In other words:

[tex]g(x+2) = 9 \times g(x)[/tex]

Using our equation for g(x), we can substitute in and simplify:

  [tex]2 \times b(x+2) = 9 \times 2\times b^x[/tex]

Simplifying, we get:

[tex]b^2[/tex] = 9

Taking the square root of both sides (we take the positive square root since b must be positive in order for g to be an increasing function), we get:

b = 3

So the final equation for g(x) is:

[tex]g(x) = 2 \times 3^x[/tex]

The solution to the system is (x,y) = (48,19).

To find the solutions to the system of equations, we need to find the values of x and y that satisfy both equations simultaneously. One way to do this is to set the two expressions for y equal to each other and solve for x:

2/3x−5 = 1/2x+3

Multiplying both sides by 6 (the least common multiple of 3 and 2) to clear the fractions, we get:

4x - 30 = 3x + 18

Simplifying, we get:

x = 48

Now that we know x, we can substitute it into either of the original equations to find the corresponding value of y. Let's use the first equation:

y = 2/3(48) - 5 = 19

So the solution to the system is (x,y) = (48,19).

Nominal variables are calculated in current year prices and real variables are measured in base year dollars to adjust for the effect of inflation by the price index.

Nominal Variable:

Nominal variables as well as dichotomous and ordinal variables constitute the three types of categorical variables. Dichotomous variables are a subtype of dummy variables that can only have two levels or categories. On the other hand, ordinal variables can have two or more categories, but they can be ordered or ordered. In addition to categorical variables, other types of variables are used, such as interval and ratio variables. An example of a dummy variable is hair color. Indeed, the hair can be of different colors like blond, black, brown, red, etc. These categories cannot be sorted and no operations can be performed.

Real Variable:

A real variable is one that does not take into account the effects of price and/or inflation. Conversely, nominal variables are variables that do not take into account the effect of inflation. As a result, changes in prices and inflation affect nominal rather than real variables. Real changes in private equity, real disposable income, real government spending, real private fixed investment, etc. The same concept of calculating real wages applies to all of these variables.
