The error step in the problem of finding an inverse is Step 4.
What is an inverse function?
In relation to the original function f, the inverse function is denoted by the symbol [tex]f^{-1}[/tex], and both the original function's domain and its range are transformed into the inverse function's domain and range, respectively.
Given, based on the inverse function
Step 1: y = 6x - 11 (Given equation)
Step 2: x = 6y - 11 (Exchange of variables x and y with each other respectively)
Step 3: x + 11 = 6y (Adding 11 on both sides)
Step 4: x/6 +11 = y Error step ( because dividing both sides by 6 will give x/6 + 11/6 = y)
Hence, the error step in the problem of finding an inverse is Step 4.

Answers
Since the test statistic is not greater than the critical value, the null hypothesis cannot be rejected. Therefore, the claim that the mean score is 71 is not rejected.
1. We are given the population of statistics final exams and asked to test the claim that the mean score is 71 using an alternative hypothesis that the mean score is different from 71. We are also given the sample statistics including the sample size (n = 26), the sample mean (ã = 72), and the sample standard deviation (s = 18). We are asked to use a significance level of α = 0.05.
2. Since we are assuming that the population is normally distributed, we will use a two-tailed z-test to test the claim.
3. The null hypothesis is that the mean score is 71 and the alternative hypothesis is that the mean score is different from 71.
4. The test statistic is calculated as:
Test statistic = (sample mean - population mean) / (standard deviation/√n)
= (72 - 71) / (18/√26)
= 0.283
5. The critical values for a two-tailed z-test with a significance level of α = 0.05 are 1.645 for both the positive and negative critical values.

The appropriate statistical decision that researcher should use is that (d) Reject the null hypothesis with either a = 0.05 or a = 0.01
The null hypothesis is a type of hypothesis that explains the population parameter and is used to examine if the provided experimental data are reliable.
Depending on whether the population or sample under consideration is viable, this hypothesis is either rejected or not.
According to the null hypothesis, there is no relationship between the independent variable and the measured event (the dependent variable). To test the null hypothesis, we don't have to think it's accurate. In contrast, you can suppose that a group of variables (dependent and independent) are connected.

The distance between the line segment from P to RQ is 2.83 units
Distance Between Two PointsDistance between two points is the length of the line segment that connects the two points in a plane. The formula to find the distance between the two points is usually given by d=√((x₂ – x₁)² + (y₂ – y₁)²). This formula is used to find the distance between any two points on a coordinate plane or x-y plane.
In this case, we need to find the coordinate of P and RQ
From P to the line RQ, we will meet the midpoint of the line RQ which has a coordinate of (3, 3)
Let's use the formula of distance of a line segment and solve this
d = √((x₂ - x₁)² + (y₂ + y₁)²)
P = (1, 1)RQ = (3, 3)d = √(3 - 1)² + (3 - 1)²

For two consecutive even integers, the result of sub-
tracting the larger integer from 3 times the smaller
integer is 14. Which of the following is the larger
integer?
Answers
Answer:
Step-by-step explanation:
By writing it as 3(n-2) - n = 14 you can solve this to get n=10
You essentially let the bigger even consecutive number equal n, and therefore the smaller even number equals n-2. Three times the smaller even equals 3(n-2) and minus the bigger even number gives 3(n-2) - n which we know equals 14.
So 3(n-2) - n = 14
3n - 6 - n = 14
2n - 6 = 14
2n = 20
n = 10

How many points are 4 units from the origin and 2 units from the linbe x=-1?
Answers
There are two points, 4 units from the origin and 2 units from the line x = -1.
What are coordinates?Coordinates are a pair of integers (Cartesian coordinates), or occasionally a letter and a number, that identify a certain place on a grid, often referred to as a coordinate plane.
Given point is at a distance of 4 units from origin,
that is √x² + y² = 4
x² + y²= 16 is the equation of the locus of the point.
The given point is also 2 units from the line x =-1
that is √(x+1)² + y² = 2
(x+1)² + y²= 4 is the equation of the locus of the point.
Subtracting the second given equation from the first one,
we get x² - (x+1)² = 12
simplifying, x = 11/2
So the common coordinate point for these 2 points which is 11/2.
Substituting this value to the first equation,
(11/2)²+ y² = 16
Simplifying, y = ±(i√57)/2.
There are 2 points whose coordinates are;
( i√57/2 , 11/2 ) and ( -i√57/2 , 11/2 ).
Therefore there are two points, 4 units from the origin and 2 units from the line x = -1.

What is exponential growth factor?
The exponential growth or decay formula is given by
x ( t ) = x₀ × ( 1 + r )ⁿ for growth rate
x ( t ) = x₀ × ( 1 - r )ⁿ for decay rate
x ( t ) is the value at time t
x₀ is the initial value at time t = 0.
r is the growth rate when r>0 or decay rate when r<0, in percent
t is the time in discrete intervals and selected time units = n
Given data ,
Let the total mass of element be = 520 grams
So , the value of x₀ = 520 grams
Now , the decay rate of element is given by r = 25.1 %
To calculate the time at which the amount of element left is 60 grams = n
where n is the total time = t
So , x ( t ) = 60
The decay rate formula is given by the equation ,
x ( t ) = x₀ × ( 1 - r )ⁿ
Substituting the values in the equation , we get
60 = 520 ( 1 - 25.1/100 )ⁿ
On simplifying the equation , we get
60 = 520 ( 1 - 0.251 )ⁿ
Divide by 520 on both sides of the equation , we get
( 0.749 )ⁿ = 6/52
Taking logarithm on both sides , we get
n × log ( 0.749 ) = log ( 6/52 )
Divide by log ( 0.749 ) on both sides , we get
n = log ( 6/52 ) / log ( 0.749 )
n = -0.9378 / -0.1255
n = 7.47 minutes
Therefore , the value of n time t = 7.5 minutes
Hence ,
The total time for the mass of the element to be 60 grams is 7.5 minutes

The Area of the given sector is 14.1 yd²
Define Sector of a Circle
A sector is referred to as a component of a circle made up of the circle's arc and its two radii. It is a section of the circle made up of the arc's circumference and the radii of the circle at its ends. A slice of pizza or a pie can be used as an analogy for the form of a circle's sector.
Given,
radius = 6 yd
Angle θ = 45°
The formula for, Sector Area = (θ / 360°) * πr²
Now, plug in the values
Sector Area = (45 / 360) * 3.14 * 6²
= 14.1 yd²

sketch a cylinder with radius 7 feet and height 10 feet, then find the total surface area using the formula
Answers
The total surface area is A≈747.7ft²
The area of the two bases and the area of the curved surface are added to determine the cylinder's total surface area. Consequently, the following is the formula for the cylinder's total surface area:
The area of the two bases plus the area of the curved surface equals the cylinder's total surface area. Due to the cylinder's round bases, their combined area will be equal to r2 + r2. We already know that a cylinder's curved surface area is 2rh.
(r2 + r2 + 2rh) is the cylinder's total surface area.
⇒ 2πr² + 2πrh
A=2πrh+2πr²
A=2·π·7·10+2·π·72≈747.69905ft²

qualitative research methods are particularly strong in studying the meanings that participants attach to events.
Answers
Yes, it's true that the interpretations that participants make of events can be best studied through qualitative research techniques like participant observation or in-depth interviews.
Going into the field without telling every subject of the field research who you are is always unethical. The following are a number of the methodologies normally utilized in qualitative research: Ethnography commonly entails researchers immediately gazing members of their herbal environments over time. A key characteristic of ethnography is the truth that herbal settings, unadapted for the researchers' interests, are used.
A famous and useful categorization separate qualitative strategies into 5 groups: ethnography, narrative, phenomenological, grounded theory, and case study. John Creswell outlines those 5 strategies in Qualitative Inquiry and Research Design. As maximum qualitative information is amassed via interactions with members via the usage of interviews, surveys, questionnaires, or awareness groups, a researcher have to discover members who're inclined to talk approximately their experiences.
