The diagram depicting the construction of copying a line segment indicates that AB = CD = 6.7 cm.

A line segment, which can be expressed as a segment of a line, has definite length. It is a line drawn that has two endpoints.

A line segment can be named by the capital letters placed at the endpoints.

Copying a line segment, therefore gives a segment of equal length as the original line segment.

Given that the length of AB = 6.7 cm, and the line segment, CD, is obtained by copying segment AB, we have;

Length of CD = Length of AB = 6.7 cm

Therefore;

The identify each representation's associated average rate of change. The average rate of change for the functions r, q, p is 5, 5, 7/3 over the range [0.3].

Given that,

We have to find over the range [0, 3], calculate each function's average rate of change. The identify each representation's associated average rate of change.

The equation for f(x) average's rate of change across [a,b] is

m=[tex]\frac{f(b)-f(a)}{b-a}[/tex]

The function provided is

r(x)=x²+2x-5

r(0)=(0)²+2(0)-5=-5

r(3)=(3)²+2(3)-5=9+6-5=15-5=10

Now,

m₁=[tex]\frac{r(3)-r(0)}{3-0}[/tex]

m₁=[tex]\frac{10+5}{3}[/tex]

m₁=15/3

m₁=5

It is clear from the graph that q(0)=2 and q(1)=3.

Now,

m₂=[tex]\frac{q(1)-q(0)}{1-0}[/tex]

m₂=[tex]\frac{3+2}{1}[/tex]

m₂=5/1

m₂=5

It is evident from the above table that s(0)=-2 and s(3)=5.

Now,

m₃=[tex]\frac{s(3)-s(0)}{3-0}[/tex]

m₃=[tex]\frac{5+2}{3}[/tex]

m₃=7/3

Therefore, The average rate of change for the functions r, q, p is 5, 5, 7/3.

The Percent Change in the number of cupcakes is 60%

The given parameters are:

Initial number of cupcakes = 70

Final number of cupcakes = 112

The Percent Change in the number of cupcakes:

Percent = (Final number of cupcakes - Initial number of cupcakes)/Initial number of cupcakes  * 100%

This gives

Percent = (112 - 70)/70 * 100%

Evaluate the quotient

So, we have

Percent = 0.6 * 100%

Evaluate the product

So, we have

Percent = 60%

Hence, the Percent Change in the number of cupcakes is 60%

In simple linear regression the estimated slope from the regression of y on x is the same as the estimated slope in the regression of x on y.

If Y depends on X then the regression line is Y on X.

Y is dependent variable and X is independent variable. If X depends on Y, then regression line is X on Y and X is dependent variable and Y is independent variable. The regression equation Y on X is Y = a + bx, is used to estimate value of Y when X is known.

What is Simple linear regression?

Simple linear regression is a regression model that estimates the relationship between one independent variable and one dependent variable using a straight line. Both variables should be quantitative.

So the change of rate of x is -1/3 .

The Derivative of a function of a real variable measures the sensitivity to change of the function value with respect to a change in its argument. Derivatives are a fundamental tool of calculus.

Given that object is decreasing at constant rate of 2 units per second so we have [tex]y = 2x^2 + 1[/tex]

[tex]\frac{dy}{dt} = 4x \frac{dx}{dt}[/tex]

given dy/dt = -2

when x = 3/2

-2 = 4(3/2) dx/dt

-2 = 6 dx/dt

dx/dt = -2/6

We get the number of elements in the set B will be 62.

The universal set is A consists of the primary one hundred positive integers.

Set B is a subset of A.

One possibility is that B consists of the primary 62 positive integers.

Then only, the greatest quantity that may be shaped through the sum of any factors of set B is 123.

The number of elements in set B is equal to  62.

We also can selectively interchange one or more elements of B and and add them in complement of B

In most of these instances the number of elements in set B might be 62.

Therefore, we get the number of elements in the set B will be 62.

the cost of 4 dozens of buttons will be $ 6 and the organizers can buy 216 buttons for $ 27.

We are given that:

Cost of 48 buttons = $ 6

48 buttons = $ 6

Divide both sides by 48:

1 button = $ 6 / 48 = $ 1 / 8

Now, the cost of 4 dozen buttons will be:

4 dozen buttons = 12 × 4 = 48

So, the cost will be 4 6 only.

For $ 27, the organizers can buy:

Number of buttons = 27 ÷ 1 / 8

Number of buttons = 27 × 8

Number of buttons = 216 buttons.

Therefore, the cost of 4 dozens of buttons will be $ 6 and the organizers can buy 216 buttons for $ 27.

The response to this question is that p has a value of 8, or the cube root of 8. i.e. p=∛8.

An integer y such that y³ = x is known as the cube root of a number x in mathematics. All nonzero complex numbers have three different complex cube roots, while all nonzero real numbers have exactly one real cube root and two complex conjugate cube roots. When we multiply a factor three times to obtain a number, we have obtained the cube root of that factor. Three cube root of, ending cubic root is the sign for the cube root. In contrast to cubing an integer, finding its cube root is a mathematical operation.

According to the equation, p³=8

We can clearly see that the power of p is 3.

Now by taking cube root on both the sides, we can see that the value of p is

∛p³=∛8

⇒p=∛8

The percentage of bags that Kia still has to make for the contest is 36 %.

We are given that:

Kia has to make 14 bags out of 25 bags.

Now, she has already made 5 gift bags.

The number of bags she still has to make = 14 - 5 = 9

Now ,we need to find the percentage of 9 from the total of 25 so to get the percentage of bags that Kia still has to make.

So, we get that:

Percentage = 9 / 25 × 100 %

Percentage = 9 × 4 %

Percentage = 36 %

A mathematical space's dimension is defined informally as the smallest number of coordinates required to specify any point within it. Thus, a line has a dimension of one since only one coordinate is required to identify a point on it - for example, the point at 5 on a number line.

2-D shapes really had no thickness and they can only be measured on two sides. Two-dimensional objects include the square, circle, rectangle, and triangle.

x=length of the shortest side

2x=length of another side

x+28=length of the third side

144=x+2x+x+28

144=4x+28

144-28=4x

116=4x

x=116/4

x=29 feet (one side)

Putting the value of x to find second side

2x=58 feet (second side)

x+28= 57 feet (third side)

the perimeter of the triangle = sum of all the sides

Two purposes dominate the use of inferential statistics: estimating population numbers (for example, the mean SAT score of all 11th graders in the US). testing hypotheses to make population-level judgments (for example, the relationship between SAT scores and family income).

Inferential statistics that are helpful in the design of experimental and quasi-experimental studies or in the assessment of program outcomes.

Step-by-step explanation:

the slope-intercept form :

y = ax + b

"a" being the slope, "b" being the y-intercept (the y value when x = 0).

but we have the slope and a point.

so, we can start with the point-slope form and then transform it :

y - y1 = a(x - x1)

"a" is again the slope, (x1, y1) is the given point.

so, we have

y - 3 = 4(x - -4) = 4(x + 4) = 4x + 16

y = 4x + 19

and that's it.
