Survey results may be impacted by response bias, sampling bias, question bias, mode of administration, and data collection method.
What is factor ?
A factor is a quantity or element that contributes to a particular result or outcome.
There are several factors that may have contributed to the different results of the two surveys:
Response Bias: The online survey may have attracted participants who are more tech-savvy and have a different perspective than those who are less comfortable with technology. On the other hand, the telephone survey may have attracted participants who are older or less mobile, and have a different perspective than those who prefer online communication.
Sampling Bias: The online survey may not have been representative of the entire population, as it was conducted on a specific website and only attracted those who use that website. Similarly, the telephone survey may have only reached those who answered the phone and were willing to participate.
Question Bias: The questions asked in the online survey may have been different from those asked in the telephone survey, leading to different results. The questions may have been worded in a way that biased the responses, either consciously or unconsciously.
Mode of Administration: The mode of administration, or the method of conducting the survey, may have influenced the responses. Online surveys allow participants to respond at their own pace and in their own environment, while telephone surveys may put pressure on participants to respond quickly and may not allow them to think through their responses.
Data Collection Method: The data collection method, such as self-reported data, may have influenced the results. Self-reported data may not always be accurate, as participants may not remember details accurately or may be unwilling to report certain information.

Peter worked 43 hours at a basic rate of 48 shillings per hour. On Friday and Saturday, he worked for two extra hours both days. The overtime rate on Friday is one and half time
and on Saturday it is double time of normal rate .
a)calculate how much each and and get their difference.
Using mathematical operations, John earned 2320 shillings in a week, Peter earned 2400 shillings in a week. Peter earned 80 shillings more than John.
An operation is a function in mathematics that transforms zero or more input values into a clearly defined output value. The operation's arity is determined by the number of operands. Scalars in MATALB can be multiplied, divided, added to, subtracted from, multiplied by, and have exponents applied to them. These operators can be used to arrange calculations involving vectors and matrices in a straightforward manner.
As per question,
John earns,
1340 per week and 10% on sales over 40,000 shillings
⇒ 1340 + (49800 - 40000) × 0.10
⇒ 2320 shillings
John earned 2320 shillings in a week
Peter earns,
43 hours at a basic rate of 48 shillings per hour
On Friday and Saturday, he worked over - time for 2 hours,
pay for Friday = 72 shillings,
pay for Saturday = 96 shillings
⇒ 43 × 48 + 72 × 2 + 96 × 2
⇒ 2400 shillings
Peter earned 2400 shillings in a week
Difference = 2400 shillings - 2320 shillings = 80

Probability to find a number odd or at most 16,
P(odd or at most 16) = 7/18
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. For an experiment having 'n' number of outcomes, the number of favorable outcomes can be denoted by x. The formula to calculate the probability of an event is as follows.
Probability(Event) = Favorable Outcomes/Total Outcomes = x/n
Given sample
Number 1 - 72
There are 36 odd numbers in between 1 to 72
Probability to find odd numbers P(odd) = 36/72 = 1/2
There are 16 numbers at most 16
Probability to find at most 16 P(at most 16)= 16/72 = 2/9
P(odd or at most 16) = P(odd) + P(at most 16) - P(odd and at most 16)
= 1/2 + 2/9 - (1/2 × 2/9)
= 1/2 + 2/9 - 2/18

4. Ashton walked into the restaurant and 4 employees are working registers. Use the trend line equation to predict how long he will wait to place his order.
The scatter plot of the data is negative association.
What is Scatterplots?Scatterplots are the plotting of set of points on a vertical axis and an horizontal axis. The shows the correlation extent between the numbers of the observed quantities.
1. Given the relationship between the number of employees working registers and the amount of time customers waited in line to order as,
y = -70x + 300
When x = 0, y = 300
When x = 1, y = 230
When x = 2, y = 160
.........................
So the value of y is decreasing as the value of x increases.
This is a negative association.
2. y = 90 seconds
-70x + 300 = 90
-70x = -210
x = 3
3. y = 3.5 minutes = 210 seconds
-70x + 300 = 210
-70x = -90
x = 9/7 = 1.3
There may be two employees working.
4. x = 4
y = (-70 × 4) + 300

The formula for a function that has vertical asymptotes is x=5 and x=8 and horizontal asymptote y=5 is f(x)=(5x²)/(x²-13x+40)
In order to find a function that fits the criteria given, you need to know how to find the asymptotes in the first place.
Vertical Asymptotes: we set the denominator equal to 0 and solve for x
Horizontal Asymptotes: we compare the degree of the numerator and denominator; if the degrees are equal, the HA equals the ratio of the leading coefficients, which is the case for this question
For the vertical asymptotes, if x = 8 and x = 5, then we can write the factors as (x - 8) and (x - 5).
For the horizontal asymptotes, if y = 5, the degree of the numerator and denominator are equal so the ratio of the leading coefficients must be 5/1.
f(x) = (5x²) / [(x-8)(x-5)] which can be rewritten as f(x) = (5x²) / (x2-13x+40)

6x + y = -39
3× + 2y = -15
Answer: The solution to the system of equations is x = 7 and y = -2.
Step-by-step explanation:
The system of equations can be solved using substitution method.
First, solve one of the equations for one of the variables. For example, from the first equation, we can solve for x:
x = (-39 - y)/6
Substitute this value of x into the second equation:
3((-39 - y)/6) + 2y = -15
Solve the resulting equation for y:
-13 - y/2 + 2y = -15
y = -2
Substitute this value of y back into the equation we used to solve for x:
x = (-39 - (-2))/6
x = 7
The solution to the system of equations is x = 7 and y = -2.
How do you find the B in Y MX B with two points and slope?
To find the B in Y = MX + B with two points and slope, choose either the point (X₁, Y₁) and slope M, then B is given by an expression Y₁ - MX₁
The slope-intercept form of equation of line is y = mx + b
where m is the slope of the line and b is the y-intercept of the line.
We need to find the value of b i.e., y-intercept when the slope and a point is given.
We know that the equation of line with slope m and passing through point (x₁, y₁) is given by the formula
(y - y₁) = m(x - x₁)
If we have been given two points (lets say (x₁, y₁) and (x₂, y₂)) and a slope, then we use above point-slope form of equation of line by choising one of the point from (x₁, y₁) and (x₂, y₂)
For point (x₁, y₁) and slope m, we simplify equation.
(y - y₁) = m(x - x₁)
y - y₁ = mx - mx₁
y = mx + (y₁ - mx₁)
Comparing above equation with slope-intercept form we get the y-intercept ,

After 5 seconds, the height will be about 65.5 feet.
One way to predict the height after 5 seconds is to use the equation of the line of best fit. The line of best fit is a line that best represents the relationship between the x and y values in the table.
To find the equation of the line of best fit, we can use the Least Squares Method.
Using the least squares method, we can calculate the slope of the line which is m=12.5, and the y-intercept which is b=3.
Therefore, the equation of the line of best fit is: y = mx + b
y = 12.5x + 3
We can use this equation to predict the height after 5 seconds by substituting x = 5 into the equation:
y = 12.5(5) + 3
y = 62.5 + 3
y = 65.5
So, after 5 seconds, the height will be about 65.5 feet.

How do you find the distance between two points in Class 9?
We can use the distance formula d=((x2 - x1)² + (y2 - y1)²) to find the distance between the two points.
What is the distance?The total movement of an object, independent of direction, is its distance.
The amount of space that an object has traveled, regardless of where it started or ended, is referred to as distance.
We can determine an object's actual size by learning how far it is from us.
The area that an object occupies in the sky can be measured.
The distance to an object is then necessary to calculate its real size.
A thing appears smaller the farther it is away.
The length of the line segment bridging two points on a planar is known as the distance between both points.
d=((x2 - x1)² + (y2 - y1)²) is a popular method for determining the distance between two points.

What is synthetic division ?Synthetic division can be defined as a simplified way of dividing a polynomial with another polynomial equation of degree 1 and is generally used to find the zeroes of polynomials.
How to illustrate the information?
It should be noted that 4x² - 17x - 15 will be:
= 4x² - 20x - 3x - 15
= (x - 5)(4x + 3)
The roots of the polynomial will be:
= f(x) = 0
(x - 5) = 0
x = 5
4x + 3 = 0
x = -3/4
