The information you gave was presented as a table with three columns: value, x-coordinate, and y-coordinate.
You would need to make a graph with the x-coordinate acting as the horizontal axis and the y-coordinate acting as the vertical axis in order to plot this data point. The size or colour of the data point would serve as a representation of the value.
Here is an illustration of a data point plot:
[tex]x | 12 | 14 | 14 | 34 \\ y | 1 | 1 | 3 | 3 \\ v | 1 | 1 | 3 | 3[/tex]
The value at the position (12,1) will be 1, the value at the point (14,1) will be 1, the value at the point (14,3) will be 3, and the value at the point (34,3) will be 3. It's vital to remember that the values on the graph can be depicted by many colours or shapes.

The first sequence rule is add 4 starting from 15. The second sequence rule is add 3 starting from 18. What is the first number that appears in both sequences?
Answer: 27
Step-by-step explanation:
Given
In the first sequence, the first term is [tex]a_1=15[/tex]
Common difference is [tex]d_1=4[/tex]
In the second sequence, the first term is [tex]b_1=18[/tex]
Common difference is [tex]d_2=3[/tex]
The nth term of the sequence is [tex]a_n=a+(n-1)d[/tex]
for the same number to appear on both sequence, the nth term must be equal
[tex]\Rightarrow 15+(n-1)4=18+(n-1)3\\\Rightarrow 3=(n-1)\\\Rightarrow n=4[/tex]
Put n=4
[tex]\Rightarrow 15+(4-1)4\\\Rightarrow 15+12=27[/tex]
Therefore, 27 is the first common term in both sequences.
If you are doing a linear regression, what is the slope of the line predicted by the null hypothesis?
The null hypothesis is that the linear regression model does not exist. This essentially means that the value of all the coefficients is equal to zero.
What is the null hypothesis?
The null hypothesis is a common statistical theory that contends that there is no statistical relationship or significance between any two sets of observed data and measured phenomena for any given single observed variable.
Here,
We have to find out the slope of the line predicted by the null hypothesis if we are doing a linear regression.
We concluded that the null hypothesis states that the slope is equal to zero, and the alternative hypothesis states that the slope is not equal to zero.
Hence, the null hypothesis is that the linear regression model does not exist. This essentially means that the value of all the coefficients is equal to zero.

Avogadro's number is a unitless object. It represents a number.
What is unit?
The mass of a particular piece of metal or the length of a particular rod are examples of quantities (specific properties) of objects that have historically been used to define measurement units. An object that has no units is known as unitless.
The proportionality factor that connects the number of constituent particles (often molecules, atoms, or ions) in a sample with the amount of material in that sample is called the Avogadro constant, also known as NA or L. It has a precise value of 6.02214076 × 10²³ reciprocal moles and serves as a SI defining constant.
The value of Avogadro's number is 6.02214076 × 10²³.

z=65,y=65,x=50
Step-by-step explanation:
Firstly, let's identify the only angle provided. The angle is an exterior angle.
The exterior angle theorm states that greater than either of the measures of the remote interior angles.
Let's remember that and start solving!
The exterior angle and x form a supplimentary line which means they create 180 degrees.
130+x=180
x=50
Now by the theorm the sum of z+y should be equal to the exterior angle which is 130.
Simply, z+y=130.
So z is equal to 65, and y is equal to 65.
Let's check our answers now.
z=65,y=65,x=50
z+x+y=180
65+50+65=180! That works :)

4x – 2y = –1 3 and –4x + 4y = –2 what does x and y equal?
Answer:
X = -7 and y = -7.5
Step-by-step explanation:
Use substitution. Let’s try to get x by itself in the second question since it seems easier.
-4x + 4y = -2
-4x = -2 -4y
x = 1/2 + y
Subsitute that into the other equation for y.
4x -2y = -13
4(1/2 + y) - 2y = -13
2 + 4y -2y = -13 # Use the distributive property
2y = -15 # put together like terms
y = -7.5
Then plug it into the x formula
x = .5 -7.5
x = -7
Answer:
The solution is (-7, -7 1/2)
Step-by-step explanation:
4x – 2y = –13
–4x + 4y = –2
-------------------------
2y = -15, and so y = -7 1/2.
Now find x. If y = -7 1/2, then, from the first equation, we get
4x - 2(-7 1/2) = -13, or
4x + 15 = -13, or
4x = -28, or x = -7
The solution is (-7, -7 1/2).

Let the random variable h represent the height of a woman in the population. P(h<60) represents the probability of randomly selecting a woman with height less than 60 inches. Based on the information given, the probability can be found using either the discrete model or the normal model. 1. Give an example of a probability h that can be found using the discrete model but not the normal model
The probability of h that can be found using the discrete model but not the normal model is 0.03.
A discrete probability distribution or DPD (also known as a discrete probability model) records all possible values of a discrete random variable and gives their probabilities.
The normal probability model involves when the distribution of the continuous outcome conforms reasonably well to a normal or Gaussian distribution, which resembles a bell-shaped curve.

How to solve algebraic fractions?An algebraic fraction is defined as a fraction whose numerator and denominator are algebraic expressions.
1) (abc + ab²)/(b²c + bc²)
Factorizing numerator and denominator gives;
ab(c + b)/bc(b + c)
b(b + c) will cancel out to get; a/c
2) (a² - b²)/(a² - a + ab - b)
Factorizing numerator and denominator gives;

How do you select sample size using simple random sampling?
Using the method of simple random sampling, The answer is we select sample before collecting data.
What do you mean by random sampling?Random sampling is a method of selecting a sample from a population in such a way that each member of the population has an equal probability of being selected. This ensures that the sample is representative of the population, and reduces bias in the sampling process. In simple random sampling, a random sample is drawn from a larger population by using random number generators, tables of random numbers, or other methods that ensure that each member of the population has an equal chance of being selected.
What are samples?A sample is a portion or a subset of a population that is selected for the purpose of studying characteristics of the population. The sample is used to make inferences or conclusions about the population from which it was drawn. The sample is usually smaller in size than the population, and it is selected through a process called sampling. The process of sampling is used to select a sample that is representative of the population, meaning that the sample has similar characteristics as the population.
In simple random sampling, the sample size is determined before collecting data. There are several ways to determine the sample size, but one common method is to use a sample size calculation formula, such as: n = (z^2 * p * (1-p)) / e^2

Joe draws a circle with center (-2, 0) and a radius of 4 units. If the scale factor is 5/2, what is the radius of a similar circle with the same center?
Answer:
The radius of a similar circle with center (-2, 0) has a length of 10 units.
Step-by-step explanation:
The radius of the new circle ([tex]R[/tex]) is the product of the former radius ([tex]r[/tex]) and the scale factor ([tex]k[/tex]), that is to say:
[tex]R = k\cdot r[/tex] (1)
If we know that [tex]k = \frac{5}{2}[/tex] and [tex]r = 4[/tex], then the radius of the new circle is:

at the age of 7, john is one of the tallest kids in his class. John is just a few inches shorter than his older brother Matthew, who, at the age of 12 is one of the shortest kids in his class
In the given case, Matthew would have a negative z score and John would have a positive z score.
A z-score is a measurement of how far an observation or data point is from the distribution's mean. An observation is said to be above the mean if the z-score is positive, while it is said to be below the mean if the z-score is negative. Therefore, it is possible that John's z-score would be positive, showing that he is taller than the average for his age group if he is one of the tallest children in his class at the age of 7.
In contrast, if 12-year-old Matthew is among the smallest students in his class, it is likely that his z-score will be negative, suggesting that he is shorter than the norm for his age group. Therefore, John would have a positive z-score but Matthew would have a negative one if he is shorter than average for his age group.
