Answer: vertical line.

Step-by-step explanation:

Ok we can define a function f(x) as "something" that maps a given input (we usually call the input "x") into a given output (we usually call the output "y")

We have one rule for functions, each input can be mapped into only one output.

So if for example, for a given value x = A.

f(A) = B

and

f(A) = C

This is mapping the input A into two different outputs, then this is not a function.

Now to the question.

If we have a vertical line (parallel to the y-axis)

This line will have only one value of x associated with it, but all the values of y.

This means that this maps one value of the input into infinite outputs, then this can not be a function.

How would I change this to standard form. <br><img src="https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20x%20-%201"

Answer:

x - 2y = 2

Step-by-step explanation:

the equation of a line in standard form is

Ax + By = C ( A is a positive integer and A, B are integers )

given y = $\frac{1}{2}$ x - 1

multiply through by 2 to eliminate the fraction

2y = x - 2 ( subtract 2y from both sides )

0 = x - 2y - 2 ( add 2 to both sides )

x - 2y = 2 ← in standard form

Car rideshare services are a popular option for people needing to move about in large cities. The scatterplot shows the distance

Bas_tet [7]

Answer:

The value of the correlation coefficient would not change.

Step-by-step explanation:

If the relationship between distance of trips and fares in dollars gives a correlation coefficient value of 0.950. This can be interpreted to mean that the relationship between both variables is strong and positive such that an increase in distance leads to corresponding increase in fares of the trip and vice versa. Thus, interchanging the axis upon which the variables are plotted would still tied the same correlation Coefficient value as the correlation coefficient does not depend on the axis upon which the variables are plotted.

The Randall farm has 22.82 acres. The Schneider farm has 22 7 over 8 acres. which farm is larger?

Marysya12 [62]

let's convert the mixed fraction to improper fraction, and then check.

$\bf \stackrel{mixed}{22\frac{7}{8}}\implies \cfrac{22\cdot 8+7}{8}\implies \stackrel{improper}{\cfrac{183}{8}}\stackrel{\textit{to decimal}}{\implies }183\div 8\implies 22.875 \\\\\\ \begin{array}{rrll} Randall&Schneider\\ \cline{1-2} 22.82&22.875\\ 22.820&\\ 820&875 \end{array}\impliedby \stackrel{\textit{so as you can see}}{820 < 875}\qquad \qquad \stackrel{therefore}{22.875 > 22.82}$

The local amusement park was interested in the average wait time at their most popular roller coaster at the peak park time (2 p

Effectus [21]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the data:

118, 124, 108, 116, 99, 125, 138, 118, 119, 121, 65, 130, 120

Ordered data:

65, 99, 108, 116, 118, 118, 119, 120, 121, 124, 125, 130, 138

1.)

90th percentile :

0.9(n + 1)th term

n = sample size = 13

0.9(14) th term

= 12.6th term

= (12 + 13)th / 2

= (130 + 138) / 2

= 134

Third quartile (Q3) = 75th percentile

0.75(n + 1)th term

n = sample size = 13

0.75(14) th term

= 10.5th term

= (10 + 11)th / 2

= (124 + 125) / 2

= 124.5

What is the first quartile?

First quartile (Q1) :

0.25(n + 1)th term

n = sample size = 13

0.25(14) th term

= 3.5th term

= (3 + 4)th / 2

= (108 + 116) / 2

= 112

(4) What is the 10th percentile?

0.1(n + 1)th term

n = sample size = 13

0.1(14) th term

= 1.4th term

= (1 + 2)th / 2

= (65 + 99) / 2

= 82

(5) 65tb percentile :

0.65(n + 1)th term

n = sample size = 13

0.65(14) th term

= 9.1th term

= (9 + 10)th / 2

= (121 + 124) / 2)

= 122.5

(6) What is the IQR?

Q3 - Q1

124.5 - 112

= 12.5

(7) What are the lower and upper limits?

Maximum = 138

Minimum = 65
