what do you think is going on here? taking all of the information in this graph, as well as the week 3 course materials on democracy and development into account, offer a falsifiable hypothesis that is designed to explain the x vs y relationship that you identified above. or, if you think there is no causal relationship, what explains the pattern(s) you see?

Answers

Answer 1

The hypothesis that I propose is that the higher the GDP per capita, the higher the percentage of population that is considered to be living in democracy.

To test this hypothesis, a simple linear regression equation can be used, where Y is the percentage of population living in democracy, and X is the GDP per capita. From the graph, we can see that the linear equation is Y = 0.0006X + 51.7. This means that, for every additional $1,000 of GDP per capita, the percentage of population living in increases by 0.6%. This could be explained by the fact that higher GDP per capita often results in higher levels of socioeconomic development, which in turn leads to better access to education, and other social services. In turn, this can lead to higher levels of political participation, which is associated with higher levels of democracy.

A spinner with repeated colors numbered from 1 to 8 is shown. Sections 1 and 8 are purple. Sections 2 and 3 are yellow. Sections 4, 5, and 6 are blue. Section 7 is orange.

A spinner divided into eight equal colored sections, with one orange, two purple, two yellow, and three blue.

Which statement about probability is true?

The probability of landing on orange is greater than the probability of landing on purple.
The probability of landing on yellow is less than the probability of landing on blue.
The probability of landing on orange is equal to the probability of landing on yellow.
The probability of landing on purple is equal to the probability of landing on blue.

Answers

Answer:  Choice B

The probability of landing on yellow is less than the probability of landing on blue.

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

Explanation:

We have the following:

There are 2 purple sections labeled "1" and "8". The probability of getting purple is 2/8.There are 2 yellow sections labeled "2" and "3". The probability of getting yellow is 2/8.There are 3 blue sections labeled "4", "5", and "6". The probability of getting blue is 3/8.There's only one orange section (labeled "7"). The probability of getting orange is 1/8.

In short,

Probability of purple = 2/8Probability of yellow = 2/8Probability of blue = 3/8Probability of orange = 1/8

Normally the goal is to reduce the fractions, but in this case it's better to keep them as they are. This allows for easier comparisons of other fractions.

------------

Now to look through the answer choices to see which are true, and which are false.

A) This is false because the probability of orange is 1/8, while the probability of purple is 2/8. We're twice as likely to get purple compared to orange. Statement A is backwards and therefore false.B) This is true. The probabilities of yellow and blue are 2/8 and 3/8 respectively. Compare the numerators to see that 2 < 3, so 2/8 < 3/8. Choice B is the final answer.C) This is false. We found that the probability of orange was 1/8, while the probability of yellow was 2/8. It's clear that 1/8 and 2/8 aren't equal. Or you could say [tex]1 \ne 2 \rightarrow 1/8 \ne 2/8[/tex]D) This is false. The probabilities of purple and blue are 2/8 and 3/8 respectively. Like with choice C, it's clear that 2/8 and 3/8 aren't equal.

a square mile can be thought of as a square that is 1 mile long on each side, or 5,280 feet on each side. united states dollar bills are 6.14 inches long. how many dollar bills laid end to end would it take to enclose a square mile?

Answers

It would take 33,792,000 dollar bills laid end to end to enclose a square mile.

To calculate this, we use the formula for the perimeter of a square: P = 4s, where P is the perimeter and s is the length of one side. Since the length of one side of a square mile is 5,280 feet, we can calculate the perimeter of a square mile in feet: P = 4(5280 ft) = 21,120 ft. Since one dollar bill is 6.14 inches long, we can convert this to feet by dividing by 12 (1 ft = 12 inches): 21,120 ft / 12 inches/ft = 1,760 ft. Finally, we can calculate the number of dollar bills needed by dividing the perimeter in feet by the length of the dollar bill in feet: 1,760 ft / 0.514 ft = 33,792,000 dollar bills.

It would take 33,792,000 dollar bills laid end to end to enclose a square mile.

an open-pit coal mine consumes 87 hectares of land, down to a depth of 30m, each year. what volume of earth, in cubic kilometers, is removed in this time?

Answers

The required volume of the earth in cubic kilometers as per given hectares of land and its depth is equal to 0.0261 km³.

Hectare of land consumed by an open -pit coal mine = 87 hectares

Convert hectare into square meters

1 hectares = 10⁴ square meter

87 hectares = 87 × 10⁴ square meter

Depth = 30 m

Area of land = 87 × 10⁴ square meter

Volume of earth = area of land × depth

⇒ Volume of earth = 87 × 10⁴ m² × 30 m

⇒ Volume of earth = 261 × 10⁵ m³

1 kilometer = 10³meters

⇒1m³ = 10⁻⁹ km³

Volume of the earth = 261 × 10⁵ × 10⁻⁹ km³

⇒Volume of the earth = 261 × 10⁻⁴ km³

                                     = 0.0261 km³

Therefore, the volume of the earth as per given area of land and depth is equal to 0.0261 km³.

what must be the probability that a randomly chosen young adult has some education beyond high school but does not have a bachelor's degree? why?

Answers

Probability: P(education beyond high school but not a bachelor's degree) = (number of young adults with education beyond high school but not a bachelor's degree) / (total number of young adults).

The probability that a randomly chosen young adult has some education beyond high school but not a bachelor's degree would be:

P(education beyond high school but not a bachelor's degree) = (number of young adults with education beyond high school but not a bachelor's degree) / (total number of young adults)

where "number of young adults with education beyond high school but not a bachelor's degree" refers to the count of individuals in the population who meet this criteria, and "total number of young adults" refers to the count of all individuals in the population who are considered young adults.

The formula calculates the probability of a certain event by dividing the number of favorable outcomes by the total number of possible outcomes. In this case, the event is a randomly chosen young adult having some education beyond high school but not a bachelor's degree. The numerator, "number of young adults with education beyond high school but not a bachelor's degree," represents the favorable outcomes, while the denominator, "total number of young adults," represents all possible outcomes.

By dividing the favorable outcomes by the total number of possible outcomes, we get the probability of the event occurring, which is a value between 0 and 1. The closer the value is to 1, the higher the probability that the event will occur. The closer the value is to 0, the lower the probability that the event will occur. This formula allows us to quantify the likelihood of an event occurring in a population based on the available data.

Answers

Without the actual values of b0 and b1, it is not possible to determine the predicted explanatory value. The correlation coefficient alone does not give enough information to make this prediction.

To find the predicted explanatory value that gives an average response value of 150, you would need to use the regression equation.

The regression equation takes the form:

y = b0 + b1x

where y is the response variable, x is the explanatory variable, b0 is the y-intercept, and b1 is the slope.

To find the x value that gives you a y value of 150, you would rearrange the equation as follows:

x = (y - b0)/b1

Answers

The slopes are :- -5, 1/3, -1/5, undefined, 1/4, -2/3, -1, -1, -2/3 and -5/2

What is slope?

The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

Given are the equations of the lines, we need to find the slope of the equation,

The general equation of a line is given by,

y = mx + c, where m is the slope and c is the y-intercept of the line.

So, finding slope of given equations by comparing them with the general equation,

1) y = -5x-1

m = -5, slope = -5

2) y = x/3-4

m = 1/3, slope = 1/3

3) y = -x/5-4

m = -1/5, slope = -1/5

4) x = 1,

Since, x=1 is a vertical line, the slope is undefined.

5) y = x/4+1

m = 1/4, slope = 1/4

6) y = -2x/3-1

m = -2/3, slope = -2/3

7) y = -x+2

m = -1, slope = -1

8) y = -x-1

m = -1, slope = -1

9) 2x+3y = 9

Converting into slope-intercept form,

2x+3y = 9

3y = -2x+9

y = -2x/3+3

m = -2/3, slope = -2/3

10) 5x+2y = 6

Converting into slope-intercept form,

5x+2y = 6

2y = -5x+6

y = -5x/2+3

m = -5/2, slope = -5/2

Hence, the slopes are :- -5, 1/3, -1/5, undefined, 1/4, -2/3, -1, -1, -2/3 and -5/2

Find the area of the surface generated when the given curve revolved about the xx-axis.y=8√xy=8x on [9,20][9,20]

Answers

As a result, the area of the surface formed by rotating the given curve about the x-axis throughout the period [9, 20] is 864π.

What is area?

The size of a region on a surface is measured in area. Surface area refers to the area of an open surface or the border of a three-dimensional object, whereas area of a plane region or plane area refers to the area of a form or planar lamina.

Here,

The area of the surface generated when a curve is revolved about an axis is known as the surface area of revolution and can be calculated using the formula:

A = 2π ∫ y dx

where y is the equation of the curve being revolved and the integral is taken over the interval [a,b] in which the curve is being revolved.

In this case, the curve is given by y = 8√x on the interval [9, 20]. So, the surface area of revolution is:

A = 2π ∫_9^20 8√x dx

This integral can be evaluated using substitution. Let u = √x, so that du = dx / 2√x and x = u^2. Then:

A = 2π ∫_3^4 8u * 2u du

= 2π * 8 * ∫_3^4 u^2 du

= 2π * 8 * [u^3/3]_3^4

= 2π * 8 * (64/3 - 27/3)

= 2π * 8 * (37/3)

= 864π

Let S be a sample space for an experiment in which every outcome is both equally likely and mutually exclusive. What can you conclude about the sum of the probabilities for all of the outcomes? Give an example.​

Answers

The conclusion abput the sum of the probabilities is that the sum for all outcomes in a sample space for the experiment is equal 1.

How to make conclusion about the sum

The sum of the probabilities for all outcomes in a sample space for an experiment must equal 1.

This is because the probability of an event is the number of favorable outcomes divided by the number of total outcomes in the sample space,

And since all outcomes are equally likely and mutually exclusive, the sum of their individual probabilities must equal 1.

Example:

Consider a fair die, the sample space S is the set of all possible outcomes {1, 2, 3, 4, 5, 6}.

if a feather is dropped from the top of a bridge 75 feet above a river, how long does it take the feather to reach the water? your answer is seconds.

Answers

The answer can be solved by using the kinematic equation, S= ut+at²/2. Here the time taken by the feather to fall from 75 feet will be 2.16 s.

Here a feather is dropped from a height of 75 ft. All other units are in SI system. So we have to convert the height to meters.

75 ft = 75/ 3.281 = 22.86 m.

We are neglecting the frictional force, or any other force acting on the feather. If the feather is under free fall, we can use the kinematic equation,

   S = ut + at²/2

S is the displacement, here the height = 22.86 m

u is the initial velocity, which is 0

t is the time

a is acceleration, here a= g, acceleration due to gravity = 9.8 m/s².

S = 0×t + 9.8t²/2

22.86 = 4.9t²

t² = 22.86/4.9

   = 4.665

t = √4.665 = 2.159 s = 2.16 s

So the time taken for the feather to reach water will be 2.16 s.

Write a
linear function f with f (0) = 3 and
f (-6) = 3.
f (x) =

Answers

Answer:The linear function f with the given points is: f(x) = 3.

The linear function is a straight line that passes through two points (0, 3) and (-6, 3). This means that the equation of the line is given by y = mx + c, where m is the gradient of the line and c is the y-intercept. In this case, the 0,3 and -6,3 points have the same y-value, so the y-intercept is equal to 3.

To find the gradient of the line, we must use the formula m = (y2-y1)/(x2-x1). Therefore, the gradient of the line is m = (3-3)/(-6-0) = 0, meaning that the equation of the line is y = 3.
