7 milimeter = 5 meter scale factor
The scale factor for 7 millimeters to 5 meters is 0.0014.
What is the scale factor?The scale factor is the ratio between the scale of an original object, drawing, map, model, or blueprint compared to its representation as a larger or smaller object.
We can compute the scale factor (scaled-down) using the following formula:
Scale factor = Dimension of the new shape ÷ Dimension of the original shape
1 meter = 1,000 millimeters
5 meters = 5,000 millimeters (1,000 x 5)
The scale-down factor of 7 millimeters to 5,000 millimeters = 0.0014 (7/5,000)
The scale-up factor of 7 millimeters to 5,000 millimeters = 714.286 (5,000/7)

HELP ASAP !! WHATS THE END BEHAVIOR ?
The degree and the leading coefficient of a polynomial function determine the end behavior of the graph.
What is end behaviour ?When referring to a function, "end behaviour" refers to the character of the value as the function parameter becomes closer to +∞ and -∞.
In the given table for f(x), we see that for every value of x, function f(x) is decreasing.
f(-2) = 48
f(0) = 12
f(2) = 3
f(3) = 1.5
In other words as the value of x increases, f(x) is approaching towards 0.
Now we take another function g(x) =
Now we plug in the values of x to get the values of g(x)
g(-1) =2^-1-5
= 1-10/2
= -9/2
= -4.5
g(0) = 2^0-5
= 1 - 5 = -4
g(2) = 2^2-5
= 4 - 5 = -1
g(3) = 2^3-5
= 8 - 5= 3
Now we find that g(x) is increasing with the values of x.
Now we take third function h(x).
By analyzing the given graph we find
h(-4) = 2
h(0) = 3
h(1) = 5
So when we are increasing the value of x function h(x) is increasing.
Finally we conclude by the options given that f(x) is the only function which tends to 0 with the increase in the values of x.

What is linear equations?Ax+By=C is the typical form for linear equations involving two variables. A linear equation in standard form is, for instance, 2x+3y=5. Finding both intercepts of an equation in this format is rather simple (x and y).A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept. Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.This problem is about linear equations. We assume Maya drive X miles, and the total cost is $Y, then we can get like, the first plan has an initial fee of $53 and costs an additional $0.11 per mile driven
For plan 1: Y = 53 + 0.11 X
The second plan has an initial fee of $42 and costs an additional $0.13 per mile driven,
For Plan 2: Y= 42 + 0.13 X
When both plans cost the same, then
Plan 1 = Plan 2
53 + 0.11 X = 42 + 0.13 X
0.13 X - 0.11 X = 53 - 42
0.02 X = 11

O 9
O 2
O 18
O 72
The longest piece of same size that can be cut from 90 inches and 72 inches pieces of wood using HCF is of length 18 inches.
So, the correct option is (c) 18.
Given that,
Jeremy has two pieces of 90 inches and the other is 72 inches wood. He wants to cut both pieces of wood into smaller pieces of same length and length as long as possible.
Therefore, the Highest Common Factor (H.C.F.) of both the lengths will gives the highest possible length i.e between both the wooden pieces.
To find Highest Common factor,
Prime factorizations of 90 and 72 :
90 = (2 x 3 x 3) x 5
72 = 2 x 2 x (2 x 3 x 3)
2 x 3 x 3 is common factor between 90 and 72
∴ The Highest Common Factor of 90 and 72 = 2 x 3 x 3 = 18
The longest possible length that can be cut out from both the pieces are of length = 18 inches
Number of pieces that can be cut from 90 inches long piece = 90/18 = 5
Number of pieces that can be cut from 72 inches long piece = 72/18 = 4
Therefore, the total number of pieces of lumber = 5+4 = 9 pieces

Answer: 57°
Step-by-step explanation:
Because the angle has a bisector ON, we should be able to add the angles together to collectively equal 106. This will help us to find c, so then we can solve <LOM.
(10c-23) + (-3c+73) = 106
Now combine like terms of the left side of the equation
7c + 50 = 106
get the variables alone on one side of the equation
7c = 56
c = 8
Now, plug in c to the equation for the degree of <LOM to solve
10(8) -23 = 80 - 23 = 57°

M) same as “K” except the bent/curved line is going from left bottom corner to right side of box like in the middle.
The graph which represents the velocity of the free-falling rock that changes during the first four seconds is option L: Same as “J” except the line is going from top left corner to bottom right corner.
What is velocity?
The pace at which an object's position changes in relation to a frame of reference and time is what is meant by velocity. Although it may appear sophisticated, velocity is just the act of moving quickly in one direction.
The velocity of a free-falling rock can depicted by equation of motion.
The first equation of motion, v = u + it is referred to as the velocity-time relation. On the other hand, the second equation of motion is s = ut + 1 / 2at² can be called the position-time relation. Likewise, we call the third equation of motion, v² = u²+ 2as, position – velocity relation.
The laws are: (1) Every object moves in a straight line unless acted upon by a force. (2) The acceleration of an object is directly proportional to the net force exerted and inversely proportional to the object's mass. (3) For every action, there is an equal and opposite reaction.
Since, the rock is falling freely it will form a straight line (first equation of motion) on the graph and not curved.
The rock will start to fall at an increasing speed with respect to time.

The most obvious concern is those who chose to respond to the survey may have different eating habits from those who did not respond.
One of the major worries when conducting a survey is that people who choose to reply can differ from those who choose not to. The term for this is nonresponse bias. The representativeness of the sample may be impacted by the traits, opinions, or actions of respondents that differ from those of non-respondents.
In this given case, the chef issued a survey to 1000 families, but only 150 of them responded, or 15% of the households. It's probable that those who are very interested in food or cooking will respond to the poll more frequently than others who aren't. Due to the possibility that the eating patterns of individuals who replied may not be typical of the total population, this could cause the sample to be skewed. Thus, the chef would need to consider the nonresponse bias when interpreting the results of the survey.

A building surmounted is in the form of a cylinder by a cone of height 24.m. If the base diameter and total height of the building are 14m and 34 m respectively, find the outer surface area of the building.
Answer: The building is in the form of a cylinder surmounted by a cone. To find the outer surface area of the building, we need to find the total surface area of the cylinder and the cone and add them together.
The total surface area of the cylinder = 2πr^2 + 2πrh = 2π(7^2) + 2π(7)(24) = 2π(49) + 2π(168) = 98π + 336π = 434π square meters
The total surface area of the cone = πr^2 + πr√(r^2 + h^2) = π(7^2) + π(7)(√(7^2 + 24^2)) = 49π + 49π(√(625)) = 49π + 49π(25) = 49π + 1225π = 1274π square meters
The outer surface area of the building is the sum of the total surface area of the cylinder and the cone, which is 434π + 1274π = 1708π square meters.

Individuals basically use statistics to make decisions in financial planning and budgeting, while organizations are guided by statistics in financial policy decisions.
What exactly do you mean by statistics?
Statistics is the study of data collection, organisation, analysis, interpretation, and presentation. When applying statistics to a scientific, industrial, or social problem, it is customary to begin with a statistical population or a statistical model to be researched.Populations can refer to a variety of groupings of individuals or things, such as "every individual living in a nation" or "each atom making up a crystal." Every facet of data, including the planning of data collecting in terms of the layout of surveys and experiments, is covered by statistics.The science of statistics focuses on creating and researching strategies for gathering, analyzing, interpreting, and presenting empirical data.Given data :
Step 1 :
The statistics department at Brigham Young University (BYU) is doing research to contrast various teaching strategies.
For lengthy courses, two technological echelons are contrasted: standard and multimedia. Eight lecture parts with students are present. There are four teachers in all.
Step 2 :
Consider that we randomly select two professors to use standard technology and the other two to use multimedia technology. Various professors will have various teaching philosophies, which will eventually influence final grades. We won't be able to tell a teaching method from a piece of technology in this way. Regarding technological disparities, there is no assurance.
Step 3 :

An intercept in mathematics is a location on the y-axis through which the line's slope passes. It is a place on the y-axis where a straight line or a curve crosses.
Here, we have
Given: f(x) = 3(2/3)ˣ
We first find the y-intercept
The y-intercept is the value of f(x) when the value of x is equal to zero
For x = 0
f(0) = 3(2/3)⁰ = 3
Point A(0,3)
Now, we find the value of f(x) when x = 1
f(1) = 3(2/3)¹ = 2
Point B(1,2)
Hence, we graph points A(0,3) and B(1,2) to find the solution.

Christmas lights are produced in a large quantity and as a result one-fifth are faulty. If
individual lights are taken out one by one from this large quantity, find the probability
that when the first three lights are taken out
a there is one faulty light
b there are two faulty lights
c there is at least one faulty light.
The probability of there is one faulty light is 0.60%, There are two faulty lights is 0.12% and There is at least one faulty light is 0.60%.
What is probability?The likelihood that an event will occur is measured by probability. It is difficult to make a complete prediction for many events. By using it, we are only able to forecast the likelihood of an event, or how likely it is, to occur. Between 0 and 1, where 1 denotes a certain event and 0 denotes an impossibility, is the range of probability. For students in class 10, probability is a crucial subject because it clarifies all of the fundamental ideas. In a sample space, there is a probability of 1 for each event.
a. Let there be 100 lights, 1/5th are faulty = 20
There is one faulty in first three, P = 3/100 × 20/100
= 0.006
= 0.60%
b. There are two faulty lights, P = 3/100 × 20/100 × 20/100
= 0.0012
= 0.12%
c. There is at least one faulty light = 3/100 ×1/5
= 0.006
= 0.60%
Thus, The probability of there is one faulty light is 0.60%, There are two faulty lights is 0.12% and There is at least one faulty light is 0.60%.

Determine the friction force on the 40 kg crate, and the resultant normal force and its position x, measured from point A, if the force P = 300 N. Take μs=0.5 and μk=0.2
The friction force on the 40 kg crate is the product of the coefficient of static friction, μs, and the normal force on the crate. Therefore, the friction force is 40 kg ×0.5 = 20 N.
The resultant normal force on the crate is the sum of the force P and the friction force, which is
300 N + 20 N = 320 N.
The position x, measured from point A, is determined by the direction of the force P. If the force P is acting to the right, then the normal force will have a position x that is to the right of point A. If the force P is acting to the left, then the normal force will have a position x that is to the left of point A.

In a residential neighborhood, the median value of a house is $200,000. For which of the following sample sizes is the sample median most likely to be above $250.000? O Impossible to determine without more information. O n = 50 O n=1000 O n=100 O n= 10
A) n = 50, Since the sample size is small, it is more likely that a higher value is selected as the median, and the sample would be skewed to the right tail.
What is the median value?
The median value of a set of data is the middle value when the data is arranged in order. It is the value that separates the higher half of the data from the lower half. In other words, it's the value that has half the observations below it and half the observations above it.
In a residential neighborhood, the median value of a house is $200,000, which means that half the houses in the neighborhood are worth more than $200,000 and half are worth less.
For a sample median most likely to be above $250.000, the sample size would have to be small and skewed to the right tail, where the higher values are. In this case, the answer would be
Hence, A) n = 50, Since the sample size is small, it is more likely that a higher value is selected as the median, and the sample would be skewed to the right tail.

Calculate the amount of interest that will be charged on $8500.00 borrowed for 6 months at 5.25%.
Answer:
A = $8,725.58
P (principal) = $8,500.00
I (interest) = $225.58
Step-by-step explanation:
First, convert R as a percent to r as a decimal
r = R/100
r = 5.25/100
r = 0.0525 rates per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 8,500.00(1 + 0.0525/12)(12)(0.5)
A = 8,500.00(1 + 0.004375)(6)
A = $8,725.58
Summary:
The total amount accrued, principal plus interest, with compound interest on a principal of $8,500.00 at a rate of 5.25% per year compounded 12 times per year over 0.5 years is $8,725.58.
