Answer: 17.63698

Step-by-step explanation:

8 kilogram is equal to 17.63698096 pounds. If You want convert kilograms to pounds, multiply the kilogram value by 2.2046226218.

Answer:

8 kg is equal to 17.6 lbs.

Step-by-step explanation:

Since 2.2 lbs is equal to 1 kg, you would have to multiply 2.2 by 8.

2.2 x 8 = 17.6

Because 2.2 multiplied by 8 is 17.6 that means 8 kg is the same as 17.6 lbs.

The only function whose range includes all real values and is both odd and even is the constant function f (x) = 0, which is precisely zero.

The constant function that is precisely zero, f (x) = 0, is the only function whose range encompasses all real values and is both odd and even. When two functions are added together, they are either even or odd.

F(x) = 0, which is defined for all real numbers, is the unique function that is both even and odd. This is merely a line that is located on the x-axis. A function that is even is the result of two even functions. An even function is the result of two odd functions. An odd function is created when an even function and an odd function are combined.

Neither an even nor an odd function is a function f(x) in which f(x) ≠ f(−x) and −f(x) ≠ f(−x) for any value of x. These functions aren't symmetrical either about the origin or the y-axis on a graph.

By using the unitary method, we can determine that 5 people are needed in the group, with 12 holes and 5 pigeons.

The Pigeonhole Principle is a mathematical theorem that states that if you have more objects than containers and all objects are placed in containers, then at least one container must have more than one object.

In the context of determining the minimum number of people needed in a group for five people to have been born in the same month, we can use the unitary method. The unitary method involves dividing the total number of possibilities by the number of objects we want to place in each container.

So, if we have 12 months in a year and we want to place 5 people in containers take one person per container, we need at least

=> 5/12 = 5/1 = 5 people in the group.

In this case, there are 12 holes and 5 pigeons. So, we need 5 people in the group to ensure that 5 of them were born in the same month.

c) P(at least 6 of the players number were drawn) = 1.84×10⁻⁴

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.

Given that, In a state lottery, a player must choose 8 of the numbers from 1 to 40. The lottery commission then performs an experiment that selects 8 of these 40 numbers.

Players has 8 combinations of numbers from 1-40. The outcome S contains all the combinations of 8 out of 40

a) P(8 of the players numbers are drawn) = 1/40/8 = 1.3×10⁻⁸

b) Number of ways of drawing 78 selected numbers from 1-40 = 8×(40-7)8×32

P(7 of the players number are drawn) = 8×32/40 =3.33×10⁻⁶

c) P(at least 6 players numbers are drawn)= 32/2×(8/6) ways to draw.

P(at least 6 players numbers are drawn) = P(all 8 chosen are drawn) + P(7 players numbers drawn) + P(6 chosen are drawn) = 1+8 x32/40/8 +[8\6 ×32/2]

The basis for the solution space is then {[1, -4, 6]}.

To find a basis for the solution space of a homogeneous system of linear equations, we can perform row operations on the augmented matrix to obtain the reduced row echelon form.

The augmented matrix for the system of linear equations is:

| 1 4 -3 | 0 |

| -2 -8 6 | 0 |

Performing row operations, we get:

| 1 4 -3 | 0 |

| 0 0 24 | 0 |

From the reduced row echelon form, we can see that the non-trivial solution is x = t, y = -4t, z = 6t for any scalar t. This means that the solution space is spanned by the single non-trivial vector [1, -4, 6].

The dimension of the solution space is 1, meaning that it is a one-dimensional subspace of the three-dimensional space of all possible solutions. The basis for the solution space is then {[1, -4, 6]}.

we have to make analogy between multiplication of ratio of filled to total sections and multiplications of numbers,

Total sections in model 1 = 5

Total semi-sections in model 2 = 10

Ratio in 1 = filled/total = 3/5

Answer: Stem and leaf plots have one advantage over histograms-- they display the original data, while histograms merely summarize them.

Step-by-step explanation:

​Stem-and-leaf plots contain original data values while histograms do not.

In order to categorise discrete or continuous variables, a stem and leaf plot, also known as a stem plot, is used. Data collection and organisation are done using a stem and leaf plot.

A bar graph is a good analogy for a stem and leaf plot. Because every number in the data is divided into a stem and a leaf, the name stem and leaf was chosen. The number's entirety - all but the final digit—is contained in the stem. There will always be one digit in the number's leaf. A stem and leaf plot's main benefit is the grouping of the data and the display of all the original data.

The mean of the distribution would be lower than the median of 82.5.

The median for the 400 observations shown in the histogram can be estimated as follows:

Since there are 400 observations, the median will be the 200th observation. The histogram shows that there are 55 observations between 90 and 100 and 155 observations between 80 and 90. Approximately 210 observations are between 80 and 100, and 140 observations are between 85 and 100.

Therefore, the 200th observation is likely to be between 80 and 85. The median can be calculated as the average of 80 and 85, which is (80 + 85) / 2 = 82.5.

If this column has a square cross-section, the width of the square cross-section is 1 km.

Let's call the width of the square cross-section "w".

The volume of the column can be calculated as the area of the cross-section multiplied by its height.

w * w * 400,000 km = 400,000 km^3

Solving for w:

w^2 * 400,000 km = 400,000 km^3

w^2 = 400,000 km^3 / 400,000 km = 1 km^2

The board weighs approximately 8.05 pounds. Hence, its density is 46.80  lb/ ft³

The density of something is a measure of how heavy it is in relation to its size. When a thing is more dense than water, it sinks; when an object is less dense than water, it floats. Density is a feature of a substance that is independent of the amount of substance.

The formula for density is given by:

ρ = m/V

Where:

ρ = density

m = mass

V = volume

In this case, the dimension of the oak board is:

wide = 5.5 inches = 0.458 feet

thick = 1.5 inches = 0.125 feet

length = 3 feet

Hence, the volume of the board is:

V = 0.458 x 0.125 x 3 = 0.172 ft³
