A train leaves the station at time t=0. Traveling at a constant​ speed, the train travels 260 kilometers in 2 hours. Answer parts a and b

Answers

Answer 1

The function which can be used to find the relation between distance and time is f(t) = 130t.

As we know the train travels 260 kilometers in 2 hours,

then the distance traveled in one hour will be 130 kilometers.

distance = 130

when time = 0 ,

distance also = 0 , as the train has not started moving yet.

Then , the function which can tell bout the  relation will be ,

f(t) = 130t

where d = f(t)

Distance is a scalar quantity which tells us about how far an object is from its starting position. Distance don't have a direction.

The distance unit of measurement in the SI

SI unit of distance is meter  in the International System of Units.

Using this as the fundamental unit and a few formulae, a large number of different derived units or quantities are produced, including volume, area, acceleration, and speed.

Distance is measured also  using the C.G.S. and M.K.S in metric unit system.

high school has 36 players on the football team. the summary of the players' weights is given in the box plot. how many players weigh between 169 and 194 pounds?

Answers

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.

Answers

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).

11. Natalee wanted to write a function which shows a 40% increase in bacteria growth.
There were 100 bacteria to start. She wrote y = 100 (40)* but she felt that she was
wrong because her y-values were extremely high when she graphed it. Identify Natalee's
mistake, and write the actual function for this scenario.

Answers

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.

Change from rectangular to cylindrical coordinates. (Let r ≥ 0 and 0 ≤ θ ≤ 2π.)
(a) (−7, 7, 7)
(√98, 7π /4​,7) Incorrect:
(b) (−7, 7 3 , 1)
(14, π /3​,1) Incorrect:

Answers

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)

Answers

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

What is a sample mean?

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.

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

Chi-square independence test.

What is Chi-square?

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.

When the cell probabilities rely on the unknown parameters, the goodness of fit test is relevant as long as the unknown parameters are substituted by their estimates and as long as one degree of freedom is subtracted for each estimated parameter.

How to determine the median of the density curve

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

We know that her goal is to knit at least 12 scarves and, at the most, 19 scarves

So it has to be bigger or equal to 15 and smaller or equal to 19, so it can't be A or D.
