The cylindrical coordinates of (−7, 7, 7) are (√98, -π/4, 7). cylindrical coordinate (−7, 7 3 , 1) is  (14, -π/3, 1).

We must switch from rectangular to cylindrical coordinates in the provided problem. (let r ≥ 0 and 0 ≤ θ ≤ 2π.)

A)(−7, 7, 7)

Given rectangular coordinates(x, y, z) =(−7, 7, 7)

The cylindrical coordinates are (r, θ, z)

As a result, we determine each value of r and θ  separately.

r = √x²+y²

r = √(-7)²+(7)²

r = √49+49

r = √98

θ = tan⁻¹ (y/x)

θ =tan⁻¹  (7/-7)

θ =tan⁻¹  (-1)

θ = -π/4

So cylindrical coordinate = (r, θ, z) = (√98, -π/4, 7)

B) (-7,7√3,1)

Given rectangular coordinates(x, y, z) = (-1,1,1)

The cylindrical coordinates are (r, θ, z)

As a result, we determine each value of r and θ  separately.

r = √x²+y²

r = √(-7)²(7√3)²

r = √49+147

r = √196

r = 14

θ = (y/x)

θ = (7√3/-7)

θ = (-√3)

θ = -π/3

So cylindrical coordinate = (r, θ, z) = (14, -π/3, 1)

Arthrogryposis, also called arthrogryposis multiplex congenita (AMC), is a term used to describe a variety of conditions involving multiple joint contractures (or stiffness).

Arthrogryposis is a general or descriptive term for the development of non progressive contractures affecting one or more areas of the body prior to birth (congenitally). A contracture is a condition in which the joint becomes permanently fixed in a bent (flexed) or straightened (extended) position, completely or partially restricting the movement of the affected joint. When congenital contractures occur only in one body area which means it is not referred to as arthrogryposis but rather as an isolated congenital contracture. The most common form of an isolated congenital contracture is clubfoot. When arthrogryposis affects two or more different areas in the  body, it may be referred to as arthrogryposis multiplex congenita (AMC).

The annual earnings for Walker will be $53223.

A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100. The percentage therefore refers to a component per hundred.

In this case, Ciara Walker was earning $47,100 and received a 13% raise.

Her new annual earnings directly will be:

= $47100 + (13% × $47100)

= $47100 + $6123

In the given sample mean, there are total 5 elements present.

An average of a group of data is called a sample mean.

A data set's central tendency, standard deviation, and variance can all be determined using the sample mean.

A population average can be determined using the sample mean, among other things.

Both the sample mean and sample median are helpful statistics for outlining a data set's core tendency.

The sample mean uses all of the data values because it is the arithmetic average.

Extreme values have no impact on the sample median, which simply uses one or two middle values.

So, we have the sample mean:

0 | 3 | 25 | 100 | 5,000

Now, in the given sample mean we can count that the number of values or the elements is 5.

Generally, A part of a line that is totally vertical is referred to as a vertical line segment. This means that the two vertices that make up the segment's ends have the same x- and y-coordinates but different z-coordinates than one another.

The length of vertical segment XY can be found by subtracting the y-coordinate of point X from the y-coordinate of point Y.

In this case, the y-coordinate of point X is 13 and the y-coordinate of point Y is 7, so the length of vertical segment XY is

A triangle is a three-sided polygon that consists of three edges and three vertices.

The incenter of a triangle is the intersection point of all the three interior angle bisectors of the triangle.

In the given triangle A is the incenter for triangle PQR.

By observing figure, AR is angle bisector of angle URK.

So,   ∠ARU = ∠ARK = 40 degree

Since, incenter point is equidistant from the sides of a triangle.

AT = AU = AK = 20

Since, PA is angle bisector of angle QPU.

So,  ∠QPA = ∠UPA

3x + 2 = 4x - 9

Subtract 3x and add 2 on both sides of equation.

4x - 3x = 9 + 2

x = 11

Now plug in x value in ∠QPA=3(11)+2

The median of the probability density curve is (c) 14

From the question, we have the following parameters that can be used in our computation:

Initial position = 1/12

Suppose we have a set {x₁, ..., xₙ}

The median is the number at the middle.

The difference between a set and a density curve is that the density curve is continuous, so getting the exact middle value can be harder.

In the given graph, we have

Constant density curve that goes from 8 to 20.

Because it is constant, the median will just be equal to the mean,

So, the median is the average between the two extreme values.

The average of two numbers a and b is calculated as

(a + b)/2

So we have

Median = (a + b)/2

Substitute the known values in the above equation, so, we have the following representation

Median = (20 + 8)/2

Natalee's mistake is that she has written the function incorrectly. In her function, she has multiplied the starting number of bacteria, 100, by the growth rate, 40%, to get the final number of bacteria. However, this is not correct because a growth rate of 40% means that the number of bacteria increases by 40% of the starting number, not by 40 itself.

To write the correct function, we can use the fact that a growth rate of 40% means that the final number of bacteria is 1.4 times the starting number. Therefore, the correct function for this scenario is y = 1.4 * 100 = <<1.4*100=140>>140. This function shows that the number of bacteria increases to 140 after experiencing a 40% increase in growth.

Answer:

The actual function for this scenario would be:

y = 100 * 1.40

Step-by-step explanation:

Natalee's mistake was that she didn't add 1 to the value of the increase. When you multiply a number by 1 plus the percentage increase, you get the correct result. In this case, the correct function would be:

y = 100 * 1.40

This function will show a 40% increase in the number of bacteria, starting with 100 bacteria. When graphed, the y-values will not be extremely high.

There are 8 players who weigh between 169 and 194 pounds.

To answer this question, we can look at the box plot to understand the distribution of weights on the football team. The box plot shows us the minimum, maximum, median, and quartiles of the team's weights. The left quartile is 169 pounds, and the right quartile is 194 pounds. This means that 25% of the team's players weigh between 169 and 194 pounds. Since the team has 36 players, 25% of 36 is 9. However, since we are looking at the number of players between 169 and 194 pounds, we need to subtract 1 since the right quartile of 194 pounds is included in the number of players. Thus, there are 8 players who weigh between 169 and 194 pounds.

Chi-square independence test.

A test that evaluates how well a model matches real observed data is the chi-square (2) statistic.

A chi-square statistic can only be calculated with data that is random, unprocessed, mutually exclusive, obtained from independent variables, and drawn from a sizable enough sample.

The outcomes of a fair coin toss, for instance, satisfy these requirements.

To test hypotheses, chi-square tests are frequently employed.

Given the size of the sample and the number of variables in the relationship, the chi-square statistic examines the size of any discrepancies between the expected results and the actual results.

According to the total number of variables and samples used in the experiment, degrees of freedom are utilized in these tests to assess whether a particular null hypothesis can be rejected. as well.

According to our question-

The independence of two variables, each of which is categorized into a variety of categories or attributes, is also tested using the chi square statistic.
