2v Next → Introduction to Geometry: Mastery Test 2 Type the correct answer in the box. Spell all words correctly. Consider these four statements about a line that passes through two points on a plane. Statement A: The line is on a different plane from the points. Statement B: The line lies on only one plane. Statement C: The line is on the same plane as the points. Statement D: The line passes through only one plane. Only statement is true​

Answers

Only Statement C, "The line is on the same plane as the points," is true.

When a line passes through two points on a plane, Statement C, "The line is on the same plane as the points," is the only true statement. This is because a line in a plane can be defined as a straight path that extends infinitely in both directions. When it passes through two points on a plane, it remains within that plane.

Statement A, "The line is on a different plane from the points," is false. If the line were on a different plane, it would not pass through the points on the original plane.Statement B, "The line lies on only one plane," is also false. A line can extend beyond the plane it is drawn on, but it remains within a single plane.Statement D, "The line passes through only one plane," is not accurate either. The line itself does not "pass-through" a plane but rather lies within a single plane.

In summary, Statement C is the only true statement, as the line remains on the same plane as the points it passes through.

The only true statement among the four options is Statement C: The line is on the same plane as the points.

To understand why Statement C is true, let's review some basic concepts in geometry. In Euclidean geometry, a plane is a flat, two-dimensional surface that extends infinitely in all directions. A line is a straight path that extends infinitely in both directions.

When a line passes through two points on a plane, it means that the line is contained within that plane. In other words, all the points on the line lie on the same plane as the given points. This is true because a plane can be defined by just three non-collinear points. Since the line passes through two points on the plane, it must lie entirely within that plane.

Statement A is false because the line is not on a different plane from the points; rather, it is on the same plane. Statement B is false because a line can lie on multiple planes if those planes intersect. Statement D is also false because the line passes through the same plane as the points.

In summary, when a line passes through two points on a plane, it is on the same plane as the points. This is the only true statement among the given options.

Two positive impacts of cold fronts​

Answers

Cold fronts can have two positive impacts on weather patterns and ecosystems.

How can cold fronts have positive impacts on weather and ecosystems?

Cold fronts can bring much-needed precipitation to an area, resulting in increased rainfall or snowfall. This can be beneficial for regions experiencing drought or in need of replenishing their water supplies. Additionally, cold fronts often bring cooler temperatures which can provide relief from hot and humid conditions, making outdoor activities more enjoyable and providing a respite from heat stress.

The cooler air can also improve air quality by reducing pollution and decreasing the likelihood of severe weather events such as thunderstorms and tornadoes. Overall, cold fronts play a crucial role in balancing weather patterns and supporting the health of ecosystems.

Answers

Despite similar latitudes (60°N & 60°S), Central Canada experiences a much colder winter temperature than the Southern tip of South America

Why does Canada experience colder winters than the southern tip of South America?

The reasons behind Canada experiencing winters more than the Southern tip of South America are: Central Canada lies in the Northern Hemisphere which is more Continental as compared to the Southern hemisphere. Hence it experiences many variations in Temperature ranges. And much colder in winter as compared to the Southern tip of South America.

South America lies in the Southern hemisphere which is more oceanic as compared to the Northern hemisphere. Hence its Temperature variation is less as compared to the Northern hemisphere. Thus it experiences a lesser colder winter than central Canada. Central Canada is surrounded by land, hence its Temperature decreases at a much higher rate & it experiences a colder winter. On the other hand, the Southern tip of South America is surrounded by water which moderates its climate.

Hence its Temperature varies at a lower rate and it experiences a lesser colder winter.

A bag contains 5 red marbles, 6 blue marbles and 3 green marbles. If three marbles are drawn out of the bag, what is the probability that all three marbles drawn will be red?

Answers

The probability of drawing three red marbles out of the bag is 5/182 or approximately 0.0275.

How to find the probability that all three marbles drawn will be red

To find the probability of drawing three red marbles out of the bag, we need to first find the total number of ways in which three marbles can be drawn from the bag, and then find the number of ways in which three red marbles can be drawn.

The total number of ways in which three marbles can be drawn from the bag is:

14C3 = (14!/(3!11!)) = 364

Where 14 is the total number of marbles in the bag.

The number of ways in which three red marbles can be drawn is:

5C3 = (5!/(3!2!)) = 10

Where 5 is the number of red marbles in the bag.

Therefore, the probability of drawing three red marbles is:

10/364 = 5/182

So the probability of drawing three red marbles out of the bag is 5/182 or approximately 0.0275.

The height of a point on the earth's face, not in the air, is generally appertained to as Elevation.

The elevation is a thing that tells how high something is raised over a face or ground line. It also refers to the process of determining effects like temperatures and degrees.

1) Because the wonderland lake is on the lower figure of about 5500 feet and is close to the crest where peaks have figure values of over to 6600 bases, its approximate elevation is about 5500 feet.

2) The chart's loftiest figure value, which is 6485 bases, makes it clear that Poorman Hill has a peak elevation of 6485 bases. The position of Poorman Hill is in this figure value.

3) The chart easily shows that Poorman Hill is roughly 6485 bases above ocean position, whereas boulder creek, which is located south of Poorman Hill, is lower than 6000 bases. As a result, Poorman Hill is advanced than the boulder creek's bank.

4, 5, and 6) detect the equals of Boulder Creek and the top of Poorman Hill on a chart. Assume that the equals of Boulder Creek are( X2, Y2) and that the top of Poorman Hill is located at( X1, Y1).

Determine the elevation difference between the two points. On the off chance that you know the height at the loftiest point of Poorman Slope( Elevation1) and the rise at Stone Rivulet( Elevation2), you can take down Elevation1 from Elevation2 to get the relief. Relief can be calculated as follows

relief = Elevation2- Elevation1

Measure the flat distance between the two focuses along the south bearing. A chart scale or an online mapping tool can be used to negotiate this.

Sketch your way on a companion, showing the heading from the loftiest point of Poorman Slope to Stone Rivulet, and name the help determined.

A government which holds total power over a country, affecting both the economy & society, is know as a_______state.

Answers

A government that holds total power over a country, affecting both the economy and society, is known as an authoritarian state.

In an authoritarian state, power is concentrated in the hands of a single individual or a small group of individuals who exercise control over all aspects of governance and decision-making. This type of government often suppresses political dissent, restricts civil liberties, and maintains strict control over the economy.

In an authoritarian state, the government's influence extends beyond political matters and into the economic and social realms. The state exerts control over industries, trade, and resources, often implementing central planning and state ownership of key sectors. Individual freedoms and rights may be curtailed, with limited political participation and freedom of expression. Censorship and surveillance are commonly used to maintain control and suppress opposition.

Authoritarian states can have varying degrees of control, ranging from mild to extreme, but they all share the common characteristic of centralized power and limited individual freedoms. These states often prioritize stability and control over individual liberties and democratic processes, leading to significant challenges in achieving political pluralism, economic diversification, and social progress.
