When you dilate the figure by a scale factor less than 1 but greater than 0, then the size of the figure decreases
The dilation is the one form of the transformation of the figure, the change the size of the figure
The scale factor is the ratio between the original size of the figure and the new size of the figure.
When the dilate the figure by a scale factor greater than one then the size of the figure increases, but when the scale factor is between 0 and 1 then the size of the figure decreases
Therefore, the size of the figure decreases after dilation

What do you mean by degree?
A unit of measure is used to measure the magnitude of an angle.
1 degree equals 1/360 of a complete revolution in magnitude.
Given that:
ΔUVW with side UW extended to X
m ∠UVW = (3x + 4)°
m ∠VWX = (8x -12)°
m ∠WUV = (x + 20)°
We know that ,
Sum of angles of triangle = 180°
m ∠UVW + m ∠WUV + m ∠VWU = 180°
m ∠VWU = 180° - (m ∠UVW + m ∠WUV)
Also we know that sum of angles on a straight line
m ∠VWX and m ∠VWU are supplementary angles
m ∠VWX + m ∠VWU = 180°
m ∠VWU = 180° - m ∠VWX
m ∠VWX = (m ∠UVW + m ∠WUV)
Substituting the given values , we get
(8x -12)° = (3x + 4)° + (x + 20)°
8x - 3x - x = 4 + 20 + 12
4x = 36

suppose the exam instructions specify that at most one of questions 1 and 2 may be included among the nine. how many different choices of nine questions are there?
The number of different choices for nine questions is 384, when at most one of questions 1 and 2 may be included among the nine.
Given, the exam instructions specify that at most one of questions 1 and 2 may be included among the nine.
We have to find the number of different choices for nine questions.
Now, using the concept of Permutation and Combinations we get
There will be three cases,
Case 1 : we include question 1
Case 2 : we include question 2
Case 3 : we neither include question 1 nor question 2
Case 1 :
question 1 is included, so question 2 can not be included and remaining 7 questions have 2 choices.
Case 2 :
question 2 is included, so question 1 can not be included and remaining 7 questions have 2 choices.
Case 3 :
neither question 1 nor question 2 is included and also remaining 7 questions have 2 choices.
Total choices = 2^7 + 2^7 + 2^7
So, the number of different choices of nine questions are 384.

A cylinder has height of 17 centimeters it volume 1921.68 cubic centimeters what is the radius cylinder
The radius of the cylinder is found to be 6 cm.
What is a right circular cylinder?A right circular cylinder is a three dimensional figure having its base and top as a circle and the height is perpendicular to circular base. The volume is given as V = πr²h.
Given that,
The height of the cylinder is 17 cm.
And, the volume is 1921.68 cm³.
Suppose the radius be r cm.
Substitute the corresponding values in the expression of volume V = πr²h as follows,
V = πr²h
=> 1921.68 = π × r² × 17
=> π × r² = 1921.68/17
=> r² = 1921.68/17π
=> r = 6
Hence, the radius of the cylinder is obtained as 6 cm.

[extra credit] how many ways are there to create an injective function from a set of 5 elements to a set of 7 elements?
There is a total of 2520 ways to create an injective function.
What is an injective function?
A function f called an injective function (sometimes called an injection, or one-to-one function) translates different elements of its domain into different elements.
Now, we can create an injective function from a set of 5 elements to a set of 7 elements
Based on the definition of an injective function,
For 1st element, we have a total of 7 choices
For 2nd element, we have a total of 6 choices and so on.
So, total ways = 7*6*5*4*3 = 2520

A nickle has a mass of 5 grams while a penny has a mass of 2. 5 grams. What is the mass in kilograms of a bag of coins containing 186 nickles and 72 pennies?.
Answer: 1.11 kg
Step-by-step explanation:
1 kg = 1000 grams
Nickle has a mass of 5 grams = 0.005 kg
Penny has a mass of 2.5 grams = 0.0025 kg
Now take 0.005 times 186 = 0.93 kg for 186 nickles
Next, take 0.0025 times 72 = 0.18 kg for 72 pennies
0.93 kg + 0.18 kg = 1.11 kg
So the bag is 1.11 kg

How to determine the length of DE?From the question, we have the following parameters that can be used in our computation:
The triangles ABC and DBE
From the question, we can see that the following corresponding sides on the triangles:
Sides AD and DB
Sides CE and EB
This implies that these sides are congruent sides
This is evident by the marks on these sides
Also from the figure, we have that:
The endpoints of the line DE is at the midpoint of lines AB and BC
This means that we have the following equation
DE = 1/2 * AB
Substitute the known values in the above equation, so, we have the following representation
DE = 1/2 * 12.6

The derivative of a function of a real variable in mathematics describes the sensitivity of the function value to a change in its argument. Calculus relies heavily on derivatives.
Solution:
Area of Circle = πr²
To find the rate of change we need to use Derivatives
dA/dt = 2πr * dr/dt

Im statistics, a type i error means rejecting the null hypothesis when it's actually true, while type ii error means failing to reject the null hypothesis when it's actually false.
The chance that you commit type i errors is known as the type i error rate or significance level (p-value). This number is conventionally and arbitrarily set to o.o5 or 5%.
