On July 4, 2017, the United States of America had a population of 325.7 million people. The total land area of the United States is 3,535,932 square miles. What was the population density of the United States on July 4, 2017? Round to the nearest tenth.

Answers

Answer 1

The population density in the United States is D = 92.1 people/mi^2

How to get the population density?

To get the population density, we need to take the quotient between the total number of people and the area.

In this case, we know that the total population is 325.7 million, and the area of the United States is  3,535,932 mi^2

Then the population density:

D = (325.7 million)/( 3,535,932 mi^2) = 9.21*10⁻⁵ million/mi^2

And we know that 1 million = 1,000,000 = 1*10⁶

Then:

9.21*10⁻⁵ million/mi^2 = 9.21*10¹ people/mi^2 = 92.1 people/mi^2

This means that in each square mile in the United States, there are around 92.1 people.

if the odds in favor of a horse winning a race is 4:7 , what is the probability of the horse winning the race?

Answers

The probability of the horse winning the race is 4/11 or approximately 0.36 or 36%.

The odds in favor of a horse winning a race is expressed as a ratio of the number of favorable outcomes to the number of unfavorable outcomes. In this case, the odds in favor of the horse winning the race is 4:7.

This means that for every 4 favorable outcomes, there are 7 unfavorable outcomes.

To determine the probability of the horse winning the race, we can use the formula:

Probability = favorable outcomes / total outcomes

In this case, the total number of outcomes is the sum of the favorable and unfavorable outcomes, which is 4 + 7 = 11.

Therefore, the probability of the horse winning the race is:

Probability = 4 / 11

This means that the horse has a probability of approximately 0.36 or 36% of winning the race.

In summary, the odds in favor of a horse winning a race of 4:7 means that there are 4 favorable outcomes for every 7 unfavorable outcomes.

Step-by-step explanation:

The angle should equal 48 degrees as it is congruent to the other angle labeled as 48 degrees.

So, we get the equation 7x + 13 = 48

Subtract 13 from both sides.

7x + 13 - 13 = 7x

48 - 13 = 35

what step is needed when constructing a circle circumscribed about a triangle?

Answers

Draw the circle with the center at the intersection of the perpendicular bisectors and the radius equal to the distance found in step 4.

When constructing a circle circumscribed about a triangle, the following step is needed:

Identify the three vertices of the triangle.

Let's say the triangle has vertices A, B, and C.

Find the perpendicular bisectors of the triangle's sides.

For each side of the triangle, construct a line that is perpendicular to the side and passes through its midpoint.

Locate the point of intersection of the perpendicular bisectors.

The point where all three perpendicular bisectors intersect is the center of the circumscribed circle.

Measure the distance from the center to any of the triangle's vertices.

This distance is the radius of the circumscribed circle.

By following these steps, you can construct a circle that passes through all three vertices of the triangle. This circle is known as the circumscribed circle or circumcircle of the triangle. It is unique to each triangle and provides a useful geometric property that can be applied in various mathematical and geometric contexts.

Algorithm II : Set the value of a variable max to the first data value. Iterate through the remaining values in the list of integers. If a data value is greater than the value of the variable max, set max to the data value. Which of the following statements best describes the behavior of the two algorithms? A Both algorithms work correctly on all input values. В Algorithm I always works correctly, but Algorithm II only works correctly when the maximum value is not the first value in the list. Algorithm Il always works correctly, but Algorithm I only works correctly when the maximum value is greater than or equal to - 1. D Neither algorithm will correctly identify the maximum value when the input contains both positive and negative input values.

Answers

Answer:  Choice C

Algorithm Il always works correctly, but Algorithm I only works correctly when the maximum value is greater than or equal to - 1

=====================================================

Explanation:

Let's say we have the data set {-4,-3,-2}. The value -2 is the largest.

If we follow algorithm 1, then the max will erroneously be -1 after all is said and done. This is because the max is set to -1 at the start even if -1 isn't in the data set. Then we see if each data value is larger than -1.

-4 > -1 is false-3 > -1 is false-2 > -1 is false

Each statement being false means we do not update the max to its proper value -2. It stays at -1.

This is why we shouldn't set the max to some random value at the start.

It's better to use the some value in the data set to initialize the max. Algorithm 2 is the better algorithm. Algorithm 1 only works if the max is -1 or larger.

Determine the inverse Fourier transforms of:
2)(2,5 pontos) Determine as transformadas de Fourier inversas de:
a) X(w) = 2d (w-1) + 3d(w) + 2d(w + 1)
b) Y(w) = 7cos (3w)
c) Y(w) = 20 nt d(W-3)/5W-5

Answers

a) To find the inverse Fourier transform of X(w) = 2δ(w-1) + 3δ(w) + 2δ(w+1), where δ(w) represents the Dirac delta function, we can apply the inverse Fourier transform formula. Using the properties of the Dirac delta function,

we know that its inverse Fourier transform is a constant function. Therefore, the inverse Fourier transform of X(w) is given by x(t) = 2e^(jωt)e^(-jω) + 3 + 2e^(jωt)e^(jω), which simplifies to x(t) = 2e^(-jωt) + 3 + 2e^(jωt).

b) For Y(w) = 7cos(3w), we can use the inverse Fourier transform properties and the Fourier transform of the cosine function. The Fourier transform of cos(at) is given by ½[δ(w - a) + δ(w + a)]. In this case, the inverse Fourier transform of Y(w) is y(t) = 7/2[δ(w - 3) + δ(w + 3)].

c) For Y(w) = 20nTδ(w - 3)/(5w - 5), where nT is the unit step function, we can use the inverse Fourier transform properties and the Fourier transform of the unit step function. The Fourier transform of nT is given by 1/(jw) + πδ(w). Substituting this into Y(w), we have Y(w) = 20[1/(jw) + πδ(w)]δ(w - 3)/(5w - 5). Simplifying this expression, the inverse Fourier transform of Y(w) is y(t) = 20[1 + πnT(t - 3)].

assume that iq is normally distributed with a mean of 90 and a sd of 10. we have a sample of size 64. we calculate a 95% confidence interval. assume we instead want a 99% confidence interval. which of the following are true?

Answers

The following statements are true: The margin of error of the 99% confidence interval will be larger than the margin of error of the 95% confidence interval. The upper and lower bounds of the 99% confidence interval will be wider than those of the 95% confidence interval.

To increase the confidence level from 95% to 99%, we would need to widen the confidence interval.

The margin of error of the 99% confidence interval will be larger than the margin of error of the 95% confidence interval.

The upper and lower bounds of the 99% confidence interval will be wider than those of the 95% confidence interval.

The confidence interval is a range of values that is likely to contain the true population mean with a certain level of confidence. Increasing the confidence level will require a wider range of values because there is a higher chance of including the true population mean within that range. The margin of error is calculated based on the sample size and standard deviation of the population. With a larger confidence level, the margin of error will increase, resulting in a wider confidence interval. Therefore, we can conclude that the margin of error of the 99% confidence interval will be larger than the margin of error of the 95% confidence interval. Additionally, the upper and lower bounds of the 99% confidence interval will be wider than those of the 95% confidence interval because the range needs to be larger to achieve a higher level of confidence.

suppose a gambler begins with an initial stake of 32 dollars, and repeatedly plays a game. in each play, the stake either doubles or is reduced to half, with either possibility having equal probability. what is the probability the gambler has strictly more than 32 dollars after playing 5 times?

Answers

The probability that the gambler has strictly more than $32 after playing the game five times is 68.75%.

Probability is a branch of mathematics that deals with the likelihood of an event occurring. In this problem, we are dealing with a gambler who is playing a game with equal probability of doubling or reducing their stake to half.

The gambler's initial stake is $32. Let us consider the possible outcomes after one play of the game. The stake can either double to $64 or reduce to $16, each with equal probability. If the stake doubles, the gambler has more than their initial stake. If the stake is reduced to half, the gambler has less than their initial stake.

Now, let us consider the possible outcomes after two plays of the game. There are four possible outcomes:

(1) the stake doubles twice and the gambler has

=> $64 * 2 = $128,

(2) the stake doubles then reduces to half and the gambler has

=> $32 * 2 * 0.5 = $32,

(3) the stake reduces to half then doubles and the gambler has

=> $32 * 0.5 * 2 = $32,

(4) the stake reduces to half twice and the gambler has

=> $32 * 0.5 * 0.5 = $8.

We can represent these outcomes using a tree diagram. Each branch represents a possible outcome, and the probability of that outcome is written next to the branch.

After five plays of the game, there are 32 possible outcomes.

We can calculate the probability of the gambler having more than their initial stake by adding up the probabilities of all the outcomes where the gambler has more than $32. This turns out to be 0.6875 or 68.75%.

What is a tangent ?

A tangent in geometry is a line that originates at an outside point and travels through a curve's Centre. When you ride a bicycle, every point on the wheel's circumference forms a tangent with the road, providing a practical illustration of a tangent. Let's use an illustration to better grasp what a tangent is. The arc S and point P outside of S are depicted in the following figure. S has been reached via a tangent from P. This serves as an illustration of a tangent.

Two crucial characteristics of the tangent are:

A tangent only hits a curve once.

A line that never reaches the inside of the circle is known as a tangent.

At the point of tangency, the tangent makes a right angle contact with the circle's radius.

A tangent to the circle also has mathematical theorems linked with it, which are needed when doing important computations in geometry in addition to the qualities mentioned above. Let's go into further depth on a couple tangents to circle theorems.

Clark finds that in an average month, he spends $35 on things he really doesn't need and can't afford. About how much does he spend on these items in a year? I came up with $420?

Answers

Clark spends $ 12775 on these items which he does not need in a year (if we consider 365 days) where the average spend in a month is $35.

Clark finds that in an average month, he spends $35 on things he really doesn't need and can't afford.

Let us consider the month in consideration here to be of 30- days and ignore any months other number of days.

Thus, calculating the average, say x' , by formula, we get,

x' = (Summation of values of all observations ) / ( Number of observations)

⇒ 35 = Total spend / 30

⇒ Total spend = $ ( 35*30)

Total spend = $ 1050

Therefore, total spend on a year, that is 12 months (considering all months to be of 30- days ) = $( 1050*12) = $ 12600

But we know a year does not have 360 days. So we calculate the total spend on these 5 days where average month spend is $35 is $175.

Hence the total spend for a year with 365 days is = $( 12600 + 175 ) = $12775
