Kinetic Energy is referred to as "energy possessed by an object as a result of its MOTION".
What is Kinetic Energy?
The energy that an item or particle has as a result of its motion is known as kinetic energy. An object accelerates and gains kinetic energy when work—the transfer of energy—is done on it by exerting a net force.
An object in motion always has a velocity, or "v," at any given moment. This energy is referred to as "kinetic energy," and it comes from:
Kinetic Energy = 12×m×v2
Here, m = Mass of the object in motion
Kinetic energy is a type of power that a moving object or particle possesses. An item accumulates kinetic energy when work, which involves the transfer of energy, is done on it by exerting a net force. A moving object or particle has kinetic energy, which depends on both its mass and its rate of motion. The type of motion can be vibration, rotation on an axis, translation (or travel along a path from one place to another), or any combination of these.
A body's translational kinetic energy is equal to 1/2mv2, which is the product of its mass, m, and square of its velocity, v.

extrapolation is the use of the regression line to estimate a mean of y-values for an x-value that is far outside the x-range of data. a. true
b. false
TRUE extrapolation is the use of the regression line to estimate a mean of y-values for an x-value that is far outside the x-range of data.
"Information available from the question"
In the question:
Extrapolation is the use of the regression line to estimate a mean of y-values for an x-value that is far outside the x-range of data.
Answer in True or False.
Now, According to the question:
Let's Know:
What is extrapolation?
A statistical technique called extrapolation aims to understand the unknown data from the known data. It uses historical data to attempt to predict future data. For instance, using the current population size and growth rate to project the size of a population in a few years.
Predicting hypothetical values outside of a specific data set is the goal of extrapolation.
Contrary to interpolation, which typically focuses on estimating past values, extrapolation is used to predict unknown future values due to its predictive nature.
Hence, TRUE extrapolation is the use of the regression line to estimate a mean of y-values for an x-value that is far outside the x-range of data.

Point Q is on line segment PR. Given PR = 10 and QR = 8 determine the length PQ.
By means of Euclidean geometry and algebra, the line segment PQ has a length of 2 units.
How to determine the length of a line segment
In this problem we find the case of a geometric system formed by a line segment PR with a point Q on the line between P and R. Thus, a line segment PQ is inside the line segment described above.
According to the statement, the lengths of the line segments PR and QR are known and the length of line segment PQ can be known by Euclidean geometry and algebra:
PR = PQ + QR
PQ = PR - QR
If we know that PR = 10 and QR = 8, then the line segment PQ is calculated below:
PQ = 10 - 8
PQ = 2
In accordance with algebra and Euclidean trigonometry, the length of line segment PQ is 2.

the scale on a map of roswell, new mexico is $1\text{ inch}:0.51\text{ mile}$. if two buildings in roswell are $2.3$ miles apart in real life, then to the nearest tenth of an inch, how far apart are they on the map?
Two Hills in Roswell is 1.173 miles apart in real life.
The mile, sometimes called the international mile or statutory mile to distinguish it from others, is an imperial unit in the United Kingdom and a common unit of distance in the United States. Both are based on old English units that are 5,280 British feet or 1,760 yards long. The legal mile was standardized in 1959 by an international agreement between the British Commonwealth and the United States and formally redefined in SI units to be exactly 1,609.344 meters.
With the modifier, the mile is also used to describe or convert a wide range of units derived from or roughly equivalent to the Roman mile, such as the Chinese mile (now exactly 500 m). will be The Romans divided the mile into 5,000 Roman feet, but the furlong was so important in Elizabethan England that in 1593 the legal mile was equal to 8 furlongs, or 5,280 feet. This form of the mile has since spread partially to the successor states of the British Empire, where they continue to use the mile.
According to the question:
The scale is 1 inch : 0.51 miles. It means 1 inch on the map represents 0.51 miles in real life.
If we have 2.3 inches on the map, then in real life

By solving a linear equation, it can be calculated that-
It takes 3.51 months for Belvedere to weigh the same as Thor
What is a linear equation?
At first it is important to know about equation
Equation shows the equality between two algebraic expressions by connecting the two algerbraic expressions by an equal to sign.
A one degree equation is known as linear equation.
A linear equation needs to be solved here
Let the number of months for Belvedere to weigh the same as Thor be x months
Thor weighs 192 pounds and plans on losing 2.1 pounds each month.
Weight of Thor after x months = 192 - 2.1x
Belvedere weighs 211 pounds and plans on losing 7.5 pounds per month.
Weight of Belvedere after x months = 211 - 7,5x
By the problem,
The linear equation is
192 - 2.1x = 211 - 7.5x
7.5x - 2.1x = 211 - 192
3.51 5.4x = 19

A retailer purchases 240 of a new brand of dvd player, of which 7 are defective. The purchase agreement says that if he tests 5 chosen at random and finds 1 or more defective, he receives all the dvd players free of charge. What is the probability that he will not have to pay for the dvd players? (round your answer to three decimal places. )
The probability of not paying any amount for the purchased DVD players as per the condition of 1 or more defective is equal to 0.9029.
As given in the condition,
Number of DVD players purchased by a retailer = 240
Number of defective DVD players = 7
Number of non- defective DVD players = 233
Number of DVD players chosen randomly for test = 5
Condition:
If 1 or more DVD players are defective then all players are free of charges.
Total number success rate for 5 DVD to be defective 'p' = 5 / 240
= 1 / 48
Here value of n = 5
Probability of non defective DVD is equal to:
= 1 - ( 47/ 48 )⁵
= 0.09708
Probability of 1 or more defective DVD's are
= 1 - 0.09708

The distribution of heights in a population of women is approximately normal. sixteen percent of the women have heights less than 62 inches. about 97.5% of the women have heights less than 71 inches.
Use the empirical rule to estimate the mean and standard deviation of the heights in this population.
Mean and standard deviation of the height of the population using empirical rule is equal to 65inches and 3 inches.
As given in the question,
Distribution of height in women population:
Percent of women heights less than 62inches = 16%
As per Empirical rule of normal distribution,
It is less than 68% it comes in first standard deviation
μ - σ = 62 __(1)
Percent of women heights less than 71 inches = 97.5%
As per Empirical rule of normal distribution,
It is in the range of 97.5% it comes in second standard deviation
μ +2σ = 71 __(2)
Solve (1) and (2) we get,
μ - σ = 62
μ +2σ = 71
0 - 3σ = -9
⇒ σ = 3inches
⇒ μ = 62 + 3
= 65inches
Therefore, the using empirical rule the mean and standard deviation to represent the height of population is equal to 65inches and 3 inches respectively.
