There are 149.91 pounds in 68 kilogram, or 68 kilogram weighs 149.91 pounds.
How much in kilogrammes are converted to pounds?The Price Per Kilogram (Pk) shall replace the Price Per Pound (Pp) (Kg)
Just divide the kg price by 2.2046 to get the lb price to convert cost per kilogramme to cost per pound.
In principle, two pounds are equal to one kilogramme (there is a longer decimal position, but I abbreviate it to 2.2046).
The weight of a kilogramme is roughly 2.2046226218 pounds. The technique can be used to convert kilogrammes to pounds and is relatively simple. The value of a kilogramme merely needs to be multiplied by 2.2046226218.
68 kg weights 149.91 pounds, or 68 kg is 149.91 pounds. Conversion of wages 149.91434 pounds (lb), 68 kilogrammes (kg)

Russel wants to calculate the amount of time it takes for a load of dirt to fall from a crane's clamshell bucket at a height of 16 feet to the bottom of a hole that is 32 feet deep. He sets up the following equation and tries to solve it. Explain the error.
16-16t²= 32
-16t² =16
t²= -1
t= ±i
1) Technically speaking, the equation has no real solution. This is because the square of a real number cannot be negative.
2) To correctly solve for the time taken for the load of dirt to fall, Russel would need to use a different method that takes into account the velocity and acceleration of the object.
What is an Equation?In its most basic form, an equation is a mathematical statement that indicates that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign.
A complicated number, symbolized by ± is the square root of a negative number. This indicates that there is no true number for t that will fulfill the equation, thus the solution to the issue is impossible to find.

The following dot plot represents student scores on both the Unit 1 and Unit 2 math tests. Scores are in whole number increments.
Part 1: Looking at the data plots, which test do you think the students scored better on? Do you think one of the tests has more variation than the other or is the variation about the same for both tests? Use complete sentences in your answer and explain your reasoning.
Part 2: Calculate the mean (rounded to the nearest whole number) and mean absolute deviation for the Unit 1 test.
Part 3: Do your results from part B prove or disprove your hypotheses from part A? Use complete sentences in your answer and explain your reasoning.
The results from Part B support the hypothesis from Part A, indicating that the students scored better on the Unit 1 test and that the Unit 1 test has more variation than the Unit 2 test.
Part 1: Looking at the data plots, it appears that the students scored better on the Unit 1 test than on the Unit 2 test. The Unit 1 test has more variation than the Unit 2 test, as there are more scores clustered towards either end of the scale, with fewer scores in the middle.
Part 2: The mean of the Unit 1 test is 77 and the mean absolute deviation is 11. This was calculated by adding up all of the scores and dividing by the total number of scores, which was 11. The mean absolute deviation was calculated by subtracting the mean from each score, taking the absolute value, and then taking the average of all of the absolute values.
Part 3: The results from Part B do support the hypothesis from Part A, as the mean score for the Unit 1 test is higher than the mean score for the Unit 2 test, as well as the mean absolute deviation for the Unit 1 test is higher than the mean absolute deviation for the Unit 2 test. This indicates that the Unit 1 test has more variation than the Unit 2 test, suggesting that the students scored better on the Unit 1 test.

A cube made of lead has a density of 11,341 kg/m3. If one of the sides were doubled without changing the mass of lead, how would the density of the cube be changed?
It would double.
It would quadruple.
It would be 18 as much.
It would be 12 as much
The density of the cube is 11341 kg/m3 and changed density if one of the sides were doubled is 5670.5 kg/m3.
Cube is a three dimensional object bounded by 6 square faces or sides and it is the only regular hexahedron . Number of edges in the cube are 12, Number of vertices in the cube are 8, Number of faces in the cube are 6.
Let side of the cube be x.
The density is the ratio between mass and the volume.
Density = x^3 = 11341
If one of the side of the cube is doubled, then density will become half of the original density.
original density = x^3 = 11341
If side is doubled, 2x*x*x=11341
Density = x^3 = 11341/2 = 5670.5 kg/m3.
Therefore, the changed density if one of the sides were doubled is 5670.5 kg/m3.

The probability of the coin landing on tail and a 4 on die is 1/12 or 0.08 or 8%
What is probability?A probability is a number that reflects the chance or likelihood that a particular event will occur. Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%
Probability = sample space / total outcome
when a coin is tossed, the probability of the tail landing = 1/2
when a die is rolled, the probability of getting a 4 = 1/6
therefore the probability of the coin to land on its tail and a 4 is on the die = 1/2×1/6 = 1/12

y is the cost and x the number of guests, then we can write:
y = k*x
k is the unit rate.
We know that it costs $20 to invite 4 people, then:
20 = k*4
20/4 = k
5 = k

What is the length of a segment drawn from the apex to the edge of the circular base
(slant height)?
Round to the nearest tenth. This is a multi-step problem so do not round until the final answer.
The segment drawn from the apex to the edge of the circular base is __ units.
The slant height of the right cone is 24.2 units, rounded to the nearest tenth.
What is the Pythagorean Theorem?
The Pythagorean theorem is a mathematical theorem that states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. It can be expressed as c² = a²+ b².
The slant height of a right cone can be found by using the Pythagorean Theorem. The radius of the circular base is half the diameter, which is 6/2 = 3 units. The volume of the cone can be found using the formula:
V = (π/3)r²h
Where r is the radius, and h is the height of the cone. Plugging in the given values, we have:
72π = (π/3)r²h
72π = (π/3)3²h
72π = (π/3)9h
72π = 3πh
24 = h
Using the Pythagorean Theorem, we can find the slant height as follows:
c² = a² + b²
Where a and b are the height and radius of the cone, and c is the slant height. Plugging in the values we have:
c² = 24² + 3²
c² = 576 + 9
c² = 585
c = 24.2
Hence, the slant height of the right cone is 24.2 units, rounded to the nearest tenth.

Which line is parallel to the line shown below?
I know D is right but I’m not sure how to get the answer.. it’s been way too long.
Answer:
D. 4x - 3y = 15
Step-by-step explanation:
The slope of a line is defined as the "change in y" over the "change in x".
This is also commonly referred to as "rise over run".
From inspection of the graphed line, we can see that the "rise" between the two points is 4 units up, and the "run" between to the two points is 3 units right. "Up" and "right" are positive directions, therefore the slope of the line is ⁴/₃.
The given answer options are all in standard form.
The standard form of a linear equation is Ax + By = C, where A, B and C are constants and A is positive.
The slope of a linear equation in standard form is -A/B.
If two lines are parallel, they have the same slope.
Therefore:
[tex]\implies \sf \dfrac{4}{3}=-\dfrac{A}{B}[/tex]
Remember that the constant A is positive, so this means that A=4 and B=-3. Therefore, we are looking for an answer option that includes "4x - 3y" on the left side of the equation.
Therefore, the line that is parallel to the graphed line is:
4x - 3y = 15Answer: Your answer will be D. [tex]4x-3y=15[/tex]
The Poolas family likes to hike along the Purple Mountain Trail. They hiked the same distance each day for 6 days, traveling a total of 25 miles. How many miles did they hike each day? Express your answer as both a fraction greater than 1 and a mixed number
If Poolas family hiked the same distance each day for 6 days, traveling a total of 25 miles, the number of miles they hiked every day is:
4 1/6 miles each day.
We are trying to find the distance that the Poolas hiked each day. We know that they hiked a total of 25 miles in 6 days.
To find the distance they hiked each day, we divide the total distance by the number of days:
25 / 6 = 4 1/6So the Poolas family hiked 4 1/6 miles each day. This answer can be expressed as a mixed number, where the whole number is 4 and the fraction is 1/6.
A mixed number is a number that combines a whole number and a fraction. In this case, the whole number represents the number of whole miles the Poolas hiked, and the fraction represents the extra distance beyond a whole mile that they hiked.

Which of the following lines would be the best fit for the data points plotted in the scatter plot below?
The line of the best fit for the data points plotted in the scatter plot is y = -0.88x + 8
How to determine the line of the best fit for the data points plotted in the scatter plot?From the question, we have the following parameters that can be used in our computation:
The graph
Using the line of the best fit, we have"
(x, y) = (8, 1) and (0, 8)
A linear equation is represented as
y = mx + c
Where
c = y when x = 0
So, we have
y = mx + 8
Using the points, we have
1 = 8m + 8
This gives
m = -0.88
So, we have
y = -0.88x + 8

A sample was taken of 20 salaries of employees in a large company. The following are the annual salaries (in thousands of dollars). For convenience, the data have been ordered. 28, 31, 34, 35, 37, 41, 42, 42, 42, 47, 49, 51, 52, 52, 60, 61, 67, 72, 75, 77.
(a) What is the median salary of the 20 employees?
(b) A histogram of the 20 salaries is slightly skewed to the right. What do we know about the mean salary of these 20 salaries, based on this information?
(c) What is the first quartile of the 20 salaries? (d) What is the interquartile range of the 20 salaries?
(a)The median salary of the 20 data's is 48 (b)The mean salary of the 20 data's is 47.65 which is less than the median due to which the histogram is slightly skewed towards right
(c)The first quartile of the 20 salary will be the first 5 datas = (28, 31, 34, 35, 37)
(d) The interquartile range of the 20 salaries will be the lenght of 2nd and 3rd quartile combined = 5 + 5 = 10 from 6th term to 15th term.
How do mean and median differ?The median value of a data set is the value at which 50% of the data points have values lower than it or equal to it and 50% of the points have values higher than it or equal to it. The median is the value that separates the upper from the lower half of a population, a probability distribution, or a sample of data. For a data collection, it may be referred to as "the middle" value.
In mathematics, particularly in statistics, there are a variety of mean types. Each mean aids in the summary of a particular set of data, frequently serving to assess the overall importance of a given data set.
The interquartile range includes the second and third quartiles, or the middle half of your data set (IQR). The range gives the spread of the full data set, whereas the interquartile range gives the range of the middle half of the data set.
The set of salary (data) :
28, 31, 34, 35, 37, 41, 42, 42, 42, 47, 49, 51, 52, 52, 60, 61, 67, 72, 75, 77.
Since there are 20 datas (even) the median will be the average of the 2 centre data = (47+49)/2 = 48
The mean of the data set = (28+ 31+ 34+ 35+ 37+ 41+ 42+ 42+ 42+ 47+ 49+ 51+ 52+ 52+ 60+ 61+ 67+ 72+ 75+ 77)/20 = 953/20 = 47.65
The first quartile of the 20 salary will be the first 5 datas = (28, 31, 34, 35, 37)
The interquartile range of the 20 salaries will be the lenght of 2nd and 3rd quartile combined = 5 + 5 = 10 from 6th term to 15th term.
