Answers
The data in the given three questions can be considered as nominal, ordinal and ratio, respectively.
The frequency (or absolute frequency) of an event in statistics is the number of times the observation occurred or was recorded in an experiment or research.Within a variable, nominal data is data that may be labelled or categorized into mutually exclusive groups. These categories cannot be meaningfully arranged.Ordinal data is a sort of categorical, statistical data in which the variables have natural, ordered categories but the distances between them are unknown.Two categories ( low vs high): frequency of values between 0-49 and frequency of values between 50-100 : nominal Three frequency (count) categories (low, medium, and high) of values ranging from 0 to 25, 26 to 74, and 75 to 100 : ordinalAnalyze each number in the set individually : ratioTo learn more about frequency, visit :

The midpoint of \overline{\text{AB}} AB is M(2, -2)M(2,−2). If the coordinates of AA are (-2, 1)(−2,1), what are the coordinates of BB?
Answers
The coordinate of point B from the given coordinates is (6, -9)
Midpoint of a coordinateThe formula for calculating the midpoint of coordinates is expressed according to the formula:
M(x, y) = {(x₁+x₂)/2, (y₁+y₂)/2}
Given the coordinate points M (2, -2) and A (-2, 1)
Substitute
2 = (x₁+x₂)/2
2 = -2+x₂/2
4 = -2 + x₂
x₂ = 6
Similarly;
Substitute
-2 = (1+y₂)/2
-4 = 1+x₂/2
-8 = 1 + y₂
y₂ = -9
Hence the coordinate of point B from the given coordinates is (6, -9)

Answers
the points will become from ( x , y ) to ( x - 5 , y + 2) and these has been plotted on the graph.
We are given the coordinates of the points:
A (3 , 2)
B (3 , 6)
C (5 , 4)
We need to plot them on the graph paper.
Now, we need to translate the points 2 units to the up and 5 units to the left.
So, the coordinates will change from ( x , y ) to ( x - 5 , y + 2)
So, we get that:
A (3 , 2) will become A' ( - 2 , 4)
B (3 , 6) will become B' ( - 2 , 8)
C (5 , 4) will become C' ( 0 , 6)
Therefore, we get that, the points will become from ( x , y ) to ( x - 5 , y + 2) and these has been plotted on the graph.

Or
2.25:1
The ratio in the form of n:1 is 2.25:1.
what is ratio?When comparing two amounts of the same sort, ratio is utilised. For two numbers, a and b, the ratio formula is written as a: b or a/b. Two or more ratios are said to be in proportion if they are all equal.
A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same sort and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
Given:
ratio 9:4
Now we have to write the ratio in the form of n:1
So, divide the ratio by 4
=9 /4 : 4/4
=9/4: 1
=2.25 :1
Hence, the ratio in the form of n:1 is 2.25:1.

Find an equation for the line below.
Answers
To find the equation of a line, you need to use the formula [tex]m=\frac{y-y_0}{x-x_0}=\frac{rise}{run}[/tex] to find the slope first.
To find the respective points that we need to plug into this formula, we need to use the axes and their values.
We can see that the first point (point on the left) has a position of (-1, -1). For the second point, we see that it has a position of (5, 1).
** remember, whenever you find the position of a point, it's always (x, y). Now that we have our values, we can plug and chug!
[tex]m=\frac{y-y_0}{x-x_0}\\m= \frac{1-(-1)}{5-(-1)} \\m=\frac{1+1}{5+1} \\m=\frac{2}{6} \\m=\frac{1}{3}[/tex]
So your answer should be 1/3 for your slope.
Now you need to find your y intercept, or what y will equal if x = 0. We can find this by using the information we now have. Remember, the equation for a linear line is [tex]y=mx+b[/tex]. So now, we plug in any of the two points (it doesn't matter which pair!) and solve for b!
[tex]y=mx+b\\-1=\frac{1}{3}(-1)+b\\ -1=-\frac{1}{3}+b\\-1+\frac{1}{3}=b\\b=-\frac{2}{3}[/tex]
Now we have b!
So now, we can fully finish the equation of this line. Your final answer should be: y = (1/3)x - 2/3 or [tex]y=\frac{1}{3}x-\frac{2}{3}[/tex].

Using the normal approximation to the binomial, there is a 0.9713 = 97.13% probability that the sum of these variables is less than 60.
What is the missing information?This problem is incomplete, but researching it on a search engine, it asks the probability that the sum of these Bernoulli variables is of less than 60.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.The binomial distribution is the probability of x successes on n trials, with p probability of a success on each trial. It can be approximated to the normal distribution with [tex]\mu = np, \sigma = \sqrt{np(1-p)}[/tex].The binomial distribution is a series of n Bernoulli trials with p probability of a success on each trial, hence the parameters for the binomial distribution are given as follows:
n = 100, p = 0.5.
The mean and the standard deviation are given by:
[tex]\mu = np = 100(0.5) = 50[/tex].[tex]\sigma = \sqrt{np(1-p)} = \sqrt{100(0.5)(0.5)} = 5[/tex]Using continuity correction, the probability that the sum is less than 60 is P(X < 59.5), which is the p-value of Z when X = 59.5, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (59.5 - 50)/5
Z = 1.9
Z = 1.9 has a p-value of 0.9713.
Hence there is a 0.9713 = 97.13% probability that the sum of these variables is less than 60.
