Answer 1

Answer:

Using the variables it gives us it is B=150m

Step-by-step explanation:

1.) $1800-$1350=$450

$1350 is the total balance after 3 months and $450 is the amount he has payed in those 3 months

2.) 450/3=150

You do 450/3 to find how much he is paying per month. If you want to check your work do 1800-1050=750 then do 750/5=150

So you put the numbers in B = Zachary's balance after m months and you get B=150m

Answers

Geometric growth is a type of exponential growth where a quantity or value increases at a fixed percentage rate over a certain period of time.

Geometric growth is a type of exponential growth where a quantity or value increases at a fixed percentage rate over a certain period of time. This means that the growth rate is proportional to the current size or value of the quantity, resulting in a continuously increasing growth rate.

Geometric growth is commonly observed in natural and social systems, such as population growth, compound interest, and the spread of infectious diseases. It is represented mathematically by an exponential function, where the base of the exponent is greater than one, indicating an increasing rate of growth over time.

So on solving the provided question, we can say that Volume of cone is \(\pi r^2\frac{h}{3}\) = 10561.39 cm cubic and  surface area  of cone = \(\pi r( r + \sqrt{ h^2 + r^2 } )\) = 37.2338688 cm sq.

what is a cone?

A cone is a three-dimensional geometric object with a flat base and a smooth tapering apex or vertex. In a plane without vertices, a cone is created by connecting a series of line segments, half-lines, or lines that are common to all points on the base. A cone is a three-dimensional structure with a seamless transition from a flat base, which is typically circular, to the vertex or apex, which serves as the axis to the base's center. An obvious three-dimensional geometric shape with an upwardly flattened curved surface is called a cone.

Volume of cone is \(\pi r^2\frac{h}{3}\)

V = 3.14*15.5*15.5*42/3 = 10561.39 cm cubic.

surface area  of cone = \(\pi r( r + \sqrt{ h^2 + r^2 } )\)

SA = \(3.14*15.5 * \sqrt{1764 + 240.25} \\3.14*15.5 * \sqrt{2004.25}\)

Answers

The bball3 dataset appears to take the form of panel data, which is a type of longitudinal data consisting of multiple observations of the same individuals over time

The bball3 dataset appears to take the form of panel data. Panel data is a type of longitudinal data where observations are made on the same individuals over time. This means that the dataset likely consists of multiple observations of a set of individuals, with the observations collected at different points in time. In a panel data set, each individual can be referred to as a ‘panel unit’.

Cross-sectional data, on the other hand, consists of observations that are collected only once, at a single point in time. This means that each observation consists of a snapshot of the population at a given moment, which is different from panel data where each observation may represent different points in time for the same individuals.

Time series data is a type of data that is collected over a period of time. It captures how a certain variable changes over time, and is often used for forecasting purposes. This is different from panel data, which captures information about the same individuals at different points in time.

In conclusion, the bball3 dataset appears to take the form of panel data, which is a type of longitudinal data consisting of multiple observations of the same individuals over time. It is not cross-sectional or time series data.

Answers

The image of point P under the reflection with the axis being the line passing through points A and D in a regular hexagon ABCDEF can be determined.

When reflecting a point across a line, the image of the point is located on the opposite side of the line but at an equal distance from the line. In this case, the reflection axis passes through points A and D.

If we examine the given options, we can eliminate options B, C, and D because their corresponding points are not on the opposite side of the line passing through A and D.

To determine the correct option, we need to consider the midpoint of the line segment connecting P and its reflected image. Since point P is a midpoint, the midpoint of the line segment between P and its reflection will be point O, the center of the hexagon. Therefore, the correct option is E) none of these.

The image of point P under the reflection with the axis being the line passing through A and D is point O, the center of the hexagon.

Let f(x) = c/(1+x2)
a) For what value of c is f a probability density function?
b) For that value of c, find P(-1

Answers

a) The value of c is f a probability density function will be c = 1/pi.

b)  that value of c, find P(-1) will be pi/2.

The value of c that makes f(x) a probability density function is:

c = 1/pi

a) For f(x) to be a probability density function, it must satisfy the following two conditions:

f(x) must be non-negative for all x.

The integral of f(x) over the entire real line must equal 1.

Let's first check the second condition:

Integral from negative infinity to positive infinity of \([c/(1+x^2)] dx = c * [arctan(x)]\)from negative infinity to positive infinity =\(c * [pi/2 + (-pi/2)] = c * pi.\)

So for the integral to equal 1, we must have:

c * pi = 1

Therefore, the value of c that makes f(x) a probability density function is:

c = 1/pi

b) To find P(-1<x<1), we need to integrate f(x) over the interval (-1, 1):

Integral from -1 to 1 of [c/(1+x^2)] dx = [arctan(x)] from -1 to 1 = [arctan(1) - arctan(-1)] = pi/2.

A hockey puck with a mass of 0.17 kg is traveling to the right along the ice at 15 m/s it strikes a second hockey puck with a mass 0.11 kg the first hockey puck comes to rest after the collision of conservation of momentum holds what is the total final momentum of the system (round your answer to the nearest tenth

Answers

Answer:

Conservation of momentum means that the final momentum must be the same as the initial momentum, where the momentum is defined as:

P = m*v

where m is mass, and v is velocity.

First, let's calculate Pi, the initial momentum.

Pi = Pi₁ + Pi₂

Where the subscripts 1 and 2 refer to each puck:

Pi₁ = 0.17kg*15m/s = 2.55 (kg*m/s)

Pi₂ = 0.11kg*0m/s = 0 (kg*m/s)

Pi = 2.55 (kg*m/s) + 0 (kg*m/s) = 2.55 (kg*m/s)

Now, after the collision we have that:

The first puck comes to rest, then:

Pf₁ = 0.17kg*0m/s =  0 (kg*m/s)

And the second puck will have a velocity v, that we want to find:

Pf₂ = 0.11kg*v

Pf = Pf₁ + Pf₂ = 0 (kg*m/s) +  0.11kg*v =  0.11kg*v

And by conservation of momentum we have:

Pi = Pf

2.55 (kg*m/s) = 0.11kg*v

We divide in both sides by 0.11kg

2.55 (kg*m/s)/0.11kg = v

23.2 m/s = v

And from this, the final momentum will be the same as the initial:

Pf = 23.2m/s*0.11kg = 2.55 (kg*m/s)

The total final momentum of the system is 2.55 Kg m/sec and this can be determined by conserving the momentum.

Given :

A hockey puck with a mass of 0.17 kg is traveling to the right along the ice at 15 m/s it strikes a second hockey puck with a mass of 0.11 kg the first hockey puck comes to rest after the collision of conservation of momentum holds.

The formula of the momentum is given below:

P = mv

Now, let conserve the moment, that is:

\(\rm P_i=P_f\)   --- (1)

where \(\rm P_i\) is the initial momentum and \(\rm P_f\) is the final momentum.

First, determine the initial momentum.

\(\rm P_i = 0.17\times 15 + 0.11\times 0= 2.55\;Kg\;m/sec\)

Now, determine the final momentum.

\(\rm P_f = 0.17\times 0+ 0.11\times v = 0.11v\;Kg\;m/sec\)

Now. substitute the value of \(\rm P_i\) and \(\rm P_f\) in the equation (1).

\(\rm 2.55=0.11v\)

v = 23.18 m/sec

So, the final momentum can be calculated as:

\(\rm P = 23.18 \times 0.11\)

P = 2.55 Kg m/sec

Translate into an algebraic expression: How much 50% sugar syrup can you make if you have x grams of sugar ?

Answers

Answer:

The algebraic expression is v = 2x

v is the volume of the sugar syrup and

x is the mass of sugar in grams.

Step-by-step explanation:

Let x be the mass of sugar in grams and v be the volume of sugar syrup.

So, mass of sugar in grams/volume of sugar syrup × 100 % = 50 %

x/v × 100 % = 50 %

x/v = 50/100

x/v = 1/2

v = 2x

So, the algebraic expression required is v = 2x where v is the volume of the sugar syrup and x is the mass of sugar in grams.

Which case is correct and why? Please advise.

Answers

The vectors x and y are not orthogonal, and case (ii) is correct: The vectors x and y are not orthogonal.

The expression for the dot product of complex vectors x and y with complex conjugates is given byx · y* = [ (i)(3-i) + (1+i)(i) ] = (3i - i² + i - 1) = (4i - 2)

When the dot product of x and y with complex conjugates is zero, the vectors are orthogonal.

Let's begin by computing the dot product of x and y with complex conjugates: (i, 1+i) · (3-i, i)*= (i)(3-i) + (1+i)(i)= 3i - i² + i + i= 4i - 1

Next, we check whether this dot product is zero or not.

If it is zero, then the given vectors are orthogonal.If 4i - 1 = 0, then 4i = 1.

Solving for i, we get:i = 1/4

Since the imaginary part of i is non-zero, we know that the dot product is not zero.

Therefore, the vectors x and y are not orthogonal, and case (ii) is correct: The vectors x and y are not orthogonal.

Answers

The study is most likely attempting to establish is Criterion validity and the study featured a(n) scale of measurement is Ordinal scale.

10). The study is most likely attempting to establish is: By criterion validity.

Criterion validity measures how well one measure predicts the outcome for another measure.

Here, we are judging how well the scores on the employment test predict the performance of the person.

Nominal Scale: This scale is used to assign labels to variables that have no numerical values.

For eg : Gender (male and female) , colour (brown blue black white)

Ordinal scale: It matters how the values are arranged, but it makes no difference how much they differ.

For eg: 1: Food applications rated from 1 to 5, 5 being the best. If a app is rated as 2 and other is rated as 4 does not mean the later is twice as good as the first.

Interval scale: An interval scale is a numerical scale where the order and size of the difference between the numbers are known. Absolute zero does not indicate absence in an interval scale, it only means there is no value.

For eg: Temperature in degree Celsius. If T1=5o Celsius  and T2=15o Celsius this means is a temperature difference of 10o , but with T3=0o does not mean there is no temperature.

Ratio scale: The ratio scale is another numerical scale where the order and size of the difference between the values are known, and where absolute zero denotes the absence of values.

For eg: Salary of people

11). The study featured a(n)scale of measurement is: By ordinal scale

We will rank the chairs on a scale where order counts and the size of the difference is not particularly significant.

Use the Divergence Theorem to calculate the surface integral S F · dS; that is, calculate the flux of F across S. F(x, y, z) = 3xy2i + xezj + z3k, S is the surface of the solid bounded by the cylinder y2 + z2 = 9 and the planes x = −3 and x = 3.

Answers

To calculate the flux of the vector field \(F = 3xy^2i + xe^zk + z^3k\)across the surface S, which is the surface of the solid bounded by the cylinder \(y^2 + z^2 = 9\)and the planes x = -3 and x = 3, we can use the Divergence Theorem.

The Divergence Theorem states that the flux of a vector field F across a closed surface S is equal to the triple integral of the divergence of F over the region enclosed by S.
First, we need to determine the divergence of F. The divergence of a vector field F = P(x, y, z)i + Q(x, y, z)j + R(x, y, z)k is given by div(F) = (∂P/∂x) + (∂Q/∂y) + (∂R/∂z).
In this case, \(F = 3xy^2i + xe^zk + z^3k,\)so we have \(P(x, y, z) = 3xy^2, Q(x, y, z) = xe^z,\)and \(R(x, y, z) = z^3\). Taking the partial derivatives, we find\((∂P/∂x) = 3y^2, (∂Q/∂y) = 0\), and (∂R/∂z) = \(3z^2\).
No can, we evaluate the triple integral of the divergence of F over the region enclosed by S. The region is defined by\(-3 ≤ x ≤ 3, -√9 - z^2 ≤ y ≤ √9 - z^2,\)and -3 ≤ z ≤ 3. Integrating (∂P/∂x) + (∂Q/∂y) + (∂R/∂z) over this region will give us the flux of F across S.
Performing the integration will yield the final numerical result of the flux.

question 9 of 10 explain how you can determine the sign of the sum of two integers if one integer is positive and the other integer is negative.

Answers

To determine the sign of the sum of two integers when one integer is positive and the other is negative, we can follow a simple rule based on their magnitudes.

If the magnitude of the positive integer is greater than the magnitude of the negative integer, the sum will be positive. This is because the positive integer outweighs the negative integer, resulting in a positive value.

On the other hand, if the magnitude of the negative integer is greater than the magnitude of the positive integer, the sum will be negative. In this case, the negative integer dominates and determines the sign of the sum.

In both scenarios, the sign of the larger magnitude integer takes precedence and determines the sign of the sum. It is important to note that the sum will always have the sign of the integer with the larger magnitude, regardless of the specific values of the integers involved.

By considering the magnitudes of the integers, we can easily determine the sign of their sum when one integer is positive and the other is negative.

the mean number of words per minute (wpm) read by sixth graders is 89 with a standard deviation of 16 wpm. if 66 sixth graders are randomly selected, what is the probability that the sample mean would be greater than 92.25 wpm?

Answers

If 66 sixth graders are randomly selected, the probability that the sample mean would be greater than 92.25 wpm is approximately 0.2142 or 21.42%.

If the sample size is sufficient, we can apply the theorem of central limitation to determine the pattern of distribution of sample means. Since n = 66 is a big enough number in this situation, we may use a normal distribution to roughly comparable the distribution of the sample means.

The general population's mean, which is 89 wpm, is the same as the mean value of the sample means. The following formula can be used to identify the average deviation of the sample means, commonly referred to as the standard deviation or error of the mean:

Standard error is equal to standard deviation squared.(sample size) Standard deviation: 16 squared(66) standard deviation: 1.969 Using the following formula, we can now standardise the sample mean: The formula for z is (sample mean - population mean) / standard error. z = (92.25 - 89) / 1.969 z = 1.732

We may determine the probability when a standard normal random variable is greater than 1.732 using the standard normal distribution table or calculator. This likelihood is roughly 0.0429, or 4.29%. we must remember that rather than just looking for any random variable, we are seeking for the probability that a sample mean is higher than 92.25 wpm. As a result, we must use the sample mean distribution, which we roughly categorized as a normal distribution.

The z-score must then be converted using the following formula to its original units of measurement: Sample mean equals population mean plus z times the standard error. 89 + 1.732 * 1.969 is the sample mean.

92.25 is the sample mean.

An inscribed angle is an angle whose vertex is a point on a circle and whose sides are two _____ of the circle

Answers

An inscribed angle is formed by two chords of a circle that intersect at a vertex located on the circle.

The angle itself is formed by the two sides of the angle, which are the line segments connecting the vertex to the endpoints of the chords. The property that makes inscribed angles interesting is that the measure of an inscribed angle is half the measure of the intercepted arc on the circle.

This relationship holds true for any inscribed angle in a circle, making it a useful concept in geometry for solving problems involving angles, arcs, and circles.

A skeptical paranormal researcher claims that the proportion of Americans that have seen a UFO, p, is less than 3 in every one thousand. Express the null and alternative hypotheses in symbolic form using the given parameter.

Answers

Symbolically, we can represent the null hypothesis as H0: p ≥ 0.003, and the alternative hypothesis as Ha: p < 0.003, where p is the true proportion of Americans who have seen a UFO.

In statistical hypothesis testing, the null hypothesis (H0) represents the default assumption or the status quo, which is assumed to be true until there is sufficient evidence to suggest otherwise. In this case, the null hypothesis is that the proportion of Americans who have seen a UFO, denoted by p, is greater than or equal to 3 in every one thousand.

The alternative hypothesis (Ha) represents the opposite of the null hypothesis, suggesting that there is evidence to reject the null hypothesis in favor of an alternative claim. In this case, the alternative hypothesis is that the proportion of Americans who have seen a UFO is less than 3 in every one thousand. This alternative hypothesis represents the claim made by the skeptical paranormal researcher.
