The relation that is a function is (d) the graph

The list of options represents the given parameter

As a general rule;

For a relation to be considered a function, the following must be true:

One x value must not point to several y values

Using the above as a guide, the ordered pair in (a), relation in (b) and table in (c) are not functions

This is because one x value must not point to several y values

However, there are unique values in the graph of (d)

Hence, (d) the graph is a function

The measure of angle ABD is 118 degree.

An equation is an expression that shows the relationship between two or more numbers and variables.

WE have been given that the angles are;

(3x +10)° and 2x

WE need to solve the value of x then we use the linear pair;

(3x +10)° + 2x = 180

Solving;

(3x +10)° + 2x = 180

5x + 10 = 180

5x = 180 - 10

5x = 170

x = 36

Angle ABD = (3x +10)° = 3(36) + 10

= 108 + 10

= 118

Hence, the measure of angle ABD is 118 degree.

Answer:

The slope is 1/3, calculate the rest from there

Step-by-step explanation:

We can picture this as a graph with the x value being the shoe size and the y being the length of a foot in inches. If we visualize it that way, we have two points on the graph: (5,9) and (11,11). From this, we can calculate the slope. The formula for slope is change in y value/change in x value, or rise/run. The slope in this case would be 2/6, simplified to 1/3. From this, we know that every time the X value increases by 1, the Y value increases by 3. Using this, you can find the two points on the line yourself. The equation formula for slope is y = mx + b. M is the slope, and Y is the y intercept (the value of Y when X = 0). Since the slope is 1/3, the equation is y = 1/3x+(y intercept). I am not going to fully solve this problem for you because I have a feeling you need this answer for a test of sorts (because of the level of urgency) but with this information you can probably solve this yourself! Good luck :)

Answer:

5. 1/2 & 3 , 6. 2 & 5

Step-by-step explanation:

5.

slope = 2

m = y2 - y1 / x2 - x1

m = 13-3/5-0

m = 10/5 or 2

y-intercept = 3

(0,3)

6.

slope = 1/2

m = y2 - y1 / x2 - x1

m = 6-5/2-0

m = 1/2

y-intercept = 5

(0,5)

The equation of each line in slope-intercept form are:

1. y = 3/4x + 4.

2. y = -x - 2

To express the equation of a line in slope-intercept form, y = mx + b, substitute the value of the slope (m) and the value of the y-intercept (b) into the equation.

1. Slope (m) = 3/4

y-intercept (b) = 4

Substitute m = 3/4 and b = 4 into the equation y = mx + b:

y = 3/4x + 4.

2. Slope (m) = -1

y-intercept (b) = -2

Substitute m = -1 and b = -2 into the equation y = mx + b:

y = -x - 2

Random sampling: It is a type of probability sampling in which the researcher randomly selects a subset of participates from the population.

Biased Sample: Sampling bias is a bias in which a sample is collected in such a way that some members of the intended population have a lower and higher sampling probability than other.

The population generalized in this case, is almost random, the only problem here is that people that want to participate will participate so is likely that the sample is not totally randomized and that there is huge number of people that regularly exercises.

b) This case is less random than the previous , here all the people in the sample regularly do exercise and these people can choose is they prefer to work with a partner or not. So the sample is biased.

In method 01 we can conclude that the result apply to the whole population , whole in method 02 we can't conclude that just because the sample is biased.

Method 01: - Recruit volunteers who are willing to participate. Randomly assign each participate to exercise with a training partner or exercise alone.

So there are people who wants to participate but people don't necessarily do exercise normally day to day life. People also can't choose to work out in a team or alone.

Method 02:  Select a random sample of people from all the people who exercise at a community fitness center. ask each person in the sample whether they use a training partner, and use the response to create the two groups.

The members in the sample are people who exercises regularly and we ask them if they work alone or with a partner then, we create two groups. so this is more biased sample.

Step-by-step explanation:

2/3 is a fraction. ALL numbers are are considered real numbers. Rational numbers are typically fractions and decimals.

2.Under feudalism, landowners were granted plots of land (called fiefs) by nobles in exchange for their loyalty and military service. The landowner, or vassal, was required to provide the lord with soldiers when needed and give him a portion of the land's produce. In return, the lord provided the vassal with protection from invaders.

Manorialism (how did it work)

Manorialism was an economic system that developed in medieval Europe. It was based on the control of land and the produce of that land by a lord. The lord would grant land to peasants in exchange for their labor and a portion of the produce. This system allowed for the development of large estates and the growth of a class of landowners.

Justinian ( identify and achivements)

Justinian was the Byzantine emperor from 527 to 565. During his reign, Justinian sought to revive the empire's greatness and reconquer the lost western half of the historical Roman Empire.

One of Justinian's most famous achievements was the construction of the Hagia Sophia, which was completed in 537. The Hagia Sophia is a former Greek Orthodox cathedral that was turned into a mosque after the Ottoman conquest of Constantinople in 1453. It is now a museum in Istanbul, Turkey.

Another of Justinian's accomplishments was the compilation of the Justinian Code, a collection of laws that codified Roman law and is still used as a reference today. The Justinian Code was instrumental in the development of modern legal systems.

vassal

The social position and duties of a vassal during the Middle Ages was to provide military service to their lord in exchange for land that they could then cultivate. Vassals were also required to attend their lord's court and give him counsel

New York City will indeed pay two men $36 million for their wrongful conviction in the 1965 assassination of a civil rights activist.

How is the chronology so that New York City pays for the incident of wrongful conviction of two people for the alleged murder of a civil rights leader?

After carrying out further investigations into the lawsuits against 2 people, in particular Muhammad A. Aziz and Khalil Islam who were accused of the murder of the leader of civil rights activist, Malcolm X, it was found that the two defendants were victims of wrongful conviction. It was previously stated that the police appeared to be withholding evidence to weaken the charges leading to acquittal. However, in the end, the court gave an acquittal because it was known that Muhammad Aziz and Khalil Islam had been proven innocent. As a form of accountability, New York City is willing to pay 26 million dollars to the victims and an additional 10 million dollars from New York state.

In conclusion, the amount of money paid by New York City is a form of responsibility that has been approved for the wrongful conviction of Muhammad Aziz and Khalil Islam.

You want the radius and water depth in a spherical bowl in which the water level is 10 cm above the center of the sphere, and the circular surface has a diameter of 30 cm.

The geometry of the diameter of the water surface can be modeled as shown in the attachment. The radius of that surface forms one leg of a right triangle with the other leg being 10 cm. The hypotenuse of the triangle is the radius of the sphere, so we have ...

  r² = 15² +10² = 325

  r = √325 = 5√13 ≈ 18.03 . . . . . cm

The water depth is 10 cm more than the radius, so is ...

  d = 10 +r = 10 +5√13 ≈ 28.03 . . . . . cm

The radius of the bowl is about 18.03 cm; the depth of water is about 28.03 cm.

The inequality that can be used to find the number of gigabytes used is 52.50+5g<75 and the value of g should be less than 4.5.

According to the question,

We have the following information:

Gabriel pays a flat cost of $52.50 per month and $5 per gigabyte. He wants to keep his bill under $75.

Now, the number of gigabytes used are represented by g.

So, we will have the following inequality:

52.50+5g<75

Now, we will solve this inequality.

Subtracting 52.50 from both the side:

5g<75-52.50

5g<22.5

Dividing by 5 on both the sides:

g<22.5/5

g<4.5

Hence, the inequality that can be used to find the number of gigabytes used is 52.50+5g<75 and the value of g should be less than 4.5.

The value of x in the inverse variation is  x = 4

Inverse variation is express mathematically by; y = k/x

where,  y and x = variables

k = constant of variation

We solve for 'x' in the variation using standard form for inverse variation:

y = k/x

Given; y = 3, x = 24

We now use the given information to find k.

Step 1: Substitute the given in to equation y= k/x; to

3 =k/24

Cross multiply

k = 3 * 24

k = 72

Step 2; The inverse relation for is y = 72/x since we have gotten k=72

For y = 18, we get
