when constructing an inscribed square by hand, which step comes after constructing a circle? (1 point)
Constructing the four lines that intersect the circumference of the circle and form the square.
How to construct a circle inscribed in a square?To construct a circle inscribed in a square, first draw a square with the desired side length.
Next, draw two diagonals from opposite corners of the square. This will divide the square into four quadrants. Measure the length of each diagonal.
Divide the length of each diagonal by two and mark the midpoints of each diagonal.
This will create four points which will define the circle. Connect each of the midpoints with a curved line to form a circle inscribed in the square.
Finally, use a compass to adjust the curve of the circle until it is perfectly symmetrical.
The circle should be perfectly centered in the square and tangent to each of its sides.

x is gamma, what is cx
"cX" is a function that takes two inputs and returns a scalar result and the value of "cX" depends on the values of the scalar "c" and the constant X.
Gamma (Γ) is a mathematical constant that is used in various areas of mathematics, including probability theory, statistics, and engineering.
The symbol "c" is a constant that represents a scalar multiplier in mathematics. This means that when you multiply a value by "c", you are multiplying it by a constant number. In this case, when we say "cX", we are multiplying the value of X (which is gamma) by the constant "c".
So, in mathematical terms, the expression "cX" can be defined as a function that takes a scalar value (c) and a constant value (X = gamma) as inputs, and returns a scalar result. This function can be used to determine the value of "cX" for a given value of "c".
It is important to note that the value of "cX" depends on the value of the scalar "c". For example, if "c" is equal to 2, then "cX" would be equal to 2 times the value of gamma.
On the other hand, if "c" is equal to 0.5, then "cX" would be equal to 0.5 times the value of gamma.
Complete Question:
Show that if X is gamma distributed and c(> 0) is a constant, then cX is gamma distributed. In particular, if X is chi-squared distributed, then cX is gamma distributed.

the marks on a statistics midterm are normally distributed with a mean of 78 and a standard deviation of 6. what proportion of the class has a midterm grade of less than 75?
The proportion of the class with a midterm grade less than 75 is approximately 0.3085, or 30.85%. This means that 30.85% of the class is expected to have a midterm grade lower than 75.
We can use the cumulative distribution function (CDF) of the normal distribution to find the proportion of the class with a midterm grade less than 75.
The CDF of a normal distribution with mean μ and standard deviation σ evaluated at a point x is given by the formula:
CDF(x) = 0.5 * [1 + erf((x - μ) / (σ * √2))]
where erf is the error function.
For this problem, μ = 78 and σ = 6, and x = 75, so the CDF can be calculated as follows:
CDF(75) = 0.5 * [1 + erf((75 - 78) / (6 * √2))]
= 0.5 * [1 + erf(-0.3536)]
The value of erf(-0.3536) can be looked up in a table or calculated using a software package. The result is approximately -0.383.
CDF(75) = 0.5 * [1 + -0.383] = 0.5 * [0.617] = 0.3085

Find the coordinates of p so that p partitions segment ab in the part-to-whole ratio of 1 to 5 with a(-9, 3) and b(1, 8). Show your work for full credit. No work - no credit.
The following formula can be used to get the coordinates of P such that P divides segment AB into parts having a part-to-whole ratio of 1 to 5 with A(-9, 3) and B(1, 8). P = (1 - t)A + TB.
What is partitions segment?A line segment can be partitioned by splitting it up into the specified number of parts. To determine how many partitions there are in the line segment, add the two values in the ratio. In order for all database nodes to participate in query execution, segmentation seeks to divide data across them uniformly. The CREATE PROJECTION statement's hash segmentation clause allows you to specify segmentation. For distributed computing, partitioning describes the arrangement of data in each node.where A and B are the coordinates of the segment's two endpoints, P's position on the segment AB is represented by the scalar value t, and
The part-to-whole ratio in this situation is 1:5, thus t equals 1/6.
In order to change the values of A, B, and t in the formula, we do as follows:
P = (1 - 1/6)A + (1/6)B
P = (5/6)A + (1/6)B
P = (-95/6, 35/6) + (1/6, 8/6)
P = (-15/2, 5/2) + (1/6, 4/3)
P = (-15/2 + 1/6, 5/2 + 4/3)
P = (-30/3, 23/6)
The positioning of P is (-10,3.83)
Regarding the second issue,
Using the same procedure as before, we can determine P's coordinates such that P divides segment AB in three equal halves if A(7, -4) and
B(-5, 4).
P = (1 - t)A + TB
The part-to-whole ratio in this situation is 3:1, therefore t equals 3/4.
In order to change the values of A, B, and t in the formula, we do as follows:
P = (1 - 3/4)A + (3/4)B
P = (1/4)A + (3/4)B
P = (7/4, -4/4) + (-53/4, 43/4)
P = (7/4 + -15/4, -4/4 + 3)
P = (-8/4, -1/4)
The positioning of P is (-2,-0.25)
Point P in the first issue is hence (-10,3.83), while Point P in the second issue is (-2,-0.25)

The relationship between the input or domain and the output or range is represented by the function rule. A relation is a function if and only if each domain value has one value in the range.
An output is produced by a function machine using an input and a set of rules. Connecting a function described by a verbal rule with corresponding values in a table is the goal of this task (one of six connections to be made between the four ways to represent a function, the other two being through its graph and through an expression).
Although this broad application is not meant to be evaluated, it encourages students to think more broadly about functions as relating objects other than numbers.

The missing angles and side of the triangle are;
m∠FXD = 44°
EG = 14
m∠FZG = 32°
How to find the angles in a triangle?We are told that the angle bisectors of ΔXYZ are XG, YG and ZG
The parameters are;
∠DYE = 94°
∠FXG = 22°
Thus;
m∠FXD = 2* 22°
m∠FXD = 44°
The sum of angles in a triangle is 180 degrees. Thus;
m∠FZE + 94 + 22 = 180
m∠FZE = 180 - (94 + 22)
m∠FZE = 64°
Thus;
m∠FZG = 64°/2
m∠FZG = 32°
The incenter of a triangle lies at equal distances from the three line segments forming the sides of the triangle, and also from the three lines containing those segments. Thus;
DG = EG = FG = 14

3.) A caterer charges $120 to cater a party for 15 people and $200 for 25 people. A.) Write an equation using x and y to find the cost of having a party catered depending on the number of people attending. B.) Describe what the x and y variables represent in your equation. C.) Use your equation to predict how much it will cost to have a party of 40 people catered. Show your work.
Answer: A) The equation can be written as y = mx + b, where m is the slope and b is the y-intercept. The slope represents the cost per person and the y-intercept represents the fixed cost. Using the two given points, we can find the slope and y-intercept:
(15, 120) and (25, 200)
m = (200 - 120) / (25 - 15) = 80 / 10 = 8
b = 120 - 8 * 15 = 120 - 120 = 0
So the equation is y = 8x.
B) In the equation y = 8x, x represents the number of people attending the party and y represents the cost of having the party catered.
C) To predict the cost of having a party of 40 people catered, we plug in x = 40 into the equation:
y = 8x
y = 8 * 40
y = 320
So it will cost $320 to have a party of 40 people catered.

It is a proportionate relationship if the ratio remains not constant constant.
What kind of relationship is proportional?As an illustration of a proportionate relationship in real life, let's look at the following: There is a correlation between the number of gallons of gas we put in our car and the price we will have to pay when we fill up the tank. That is to say, the more gas we use, the more we will have to pay.
When two variables are correlated in a manner that their ratios are equal, this is known as a proportional relationship. The "constant of proportionality" is a term used to describe this constant.
Examining the ratios between the two variables will help you determine whether a relationship is proportional. It is a proportionate relationship if the ratio remains constant.
