Answer:
Sampling bias
Step-by-step explanation:
Sampling bias is due to the mistaken manner of selection of the respondents for the survey when conducting market research or similar survey. The sampling bias error is said to have occurred when the sample selection procedure, methodology, or process focuses on part of the population with a particular attribute, rather than being a random sample. Such that a given subset of the of the population are selected for the survey, which results in a biased sample.

On average Asia makes 14 out of 20 free throws Assuming the relationship is proportional, how many free throws is she likely to make if she shot 150 free throws?
Answer:
105
Step-by-step explanation:
14:20=7:10
150/10=15
7x15=105
Asia will make 105 free throws out of 120 free throws
Let the number of free throws that can be made be represented by x.
Based on the information given in the question, the equation to use in solving the question will be:
14/20 = x/150
Cross multiply
20 × x = 14 × 150
20x = 2100
x = 2100/20
x = 105
Therefore, Asia will make 105 free throws out of 120 free throws
In conclusion, 105 free throws will be made.

Is the following statement true or false?
The intersection of a plane and a line segment can be a line segment.
true
false
Answer:
False. Line segments are one dimensional, therefore any interaction they have with a plane will be a point.
Step-by-step explanation:
The statement 'The intersection of a plane and a line segment can be a line segment' is True.
What is plane?"It is a two-dimensional flat surface with no edges or thickness. "
What is line?"It a one-dimensional geometric figure, which has length but no width."
For given question,
If the line lies within the plane then the intersection of a plane and a line segment can be a line segment.
If the line does not lie on the plane then the intersection of a plane and a line segment can be a point.
Therefore, the statement 'The intersection of a plane and a line segment can be a line segment.' is True.

What is an equation of the line that passes through the point (4,1) and is
perpendicular to the line 2x - y = 4?
Answer:
Point-Slope Form: y - 1 = -1/2(x - 4) or Standard Form: y = -1/2x + 3
Step-by-step explanation:
For a line to be perpendicular, you take the negative inverse of the slope of 2x - y = 4. To do this, rearrange the y to one side and you get y = 2x - 4. The slope of the line is 2. So, taking the negative inverse would be -1/m (with m being slope of the the equation given in the problem. This would give you -1/2.
Using point slope formula, y - y1 = m(x - x1), you can plug in the point given, (4,1) and the slope you found to get y - 1 = -1/2(x - 4). For standard form, isolating the y gets you y = -1/2x + 3.
You can check your answer by using Desmos by putting in the line 2x - y = 4, the point (4,1), and the equation you got as your answer. You will see that the equation is perpendicular to 2x - y = 4 and passes through point (4,1). Your equation of the line is y - 1 = -1/2(x - 4) or y = -1/2x + 3
Hope this helps!
Here, we are required to find the equation of the line that passes through the point (4,1) and is
perpendicular to the line 2x - y = 4.
The equation of the line is: y = (-x/2) + 3
First, the product of the slopes of 2 perpendicular lines is -1.
Therefore, M1 × M2 = -1.
By rearranging the equation 2x - y = 4 to mimic the equation of a straight line; y = mx + c.
we have, y = 2x + 4 and obviously slope, m1 = 2.
Therefore, since M2 = -1/M1 from above;
M2 = -1/2
Therefore, the equation of the required line is given by;
M2 = (y - y1)/(x - x1)
where, M2 = -1/2, y1 = 1 and x1 = 4.
Ultimately, -1/2 = (y - 1)/(x - 4)
The equation of the line is then given as;
y = (-x/2) + 3.

A courier service charges a flat rate of $12.50 per trip plus $0.60 per mile. They charged Films and More $23.30 to deliver a package.
A: Write the equation that represents this scenario.
B: How many miles did the courier service have to travel?
Answer:
all you have to do is multiply that and get the answer
The equation that represents this scenario. y = 0.6x + 12.5 and the courier service to travel 18 miles.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can ais lso be used to indicate the logical syntax's order of operations and other features.
Create an equation where y is the cost to deliver a package, and x is the number of miles traveled.
Since the service charges $0.60 per mile, the cost can be represented by $0.60x.
There is a flat rate of $12.50, so this will be added to 0.60x. Then, set this equal to y. Using this, create an equation:
y = 0.6x + 12.5
A number of miles the courier service had to travel by plugging in 23.30 as y and solving for x:
y = 0.6x + 12.5
23.3 = 0.6x + 12.5
10.8 = 0.6x
18 = x
Therefore, the equation that represents this scenario. is y = 0.6x + 12.5 and the courier service to travel 18 miles.

A car is traveling down a highway at a constant speed, described by the equation d=65t, where d represents the distance, in miles, that the car travels at this speed in t hours.
Answer:
Step-by-step explanation:
We are given an equation d = 65 t, where d represents the distance, in miles, that the car travels at this speed in t hours.
We know distance, speed and time relation
d = s * t.
Where d represents the distance, that the car travels at this speed in t at the speed s.
If we compare that relation with the given equation, we can see s = 65.
So,
a) The 65 tell us speed of 65 miles per hour in this situation.
b) Second part seems to be incorrect. Please check it again.
c) We are given distance = 26 miles.
Plugging d= 26 in the given equation.
26 = 65 t
Dividing both sides by 65, we get
26/65 = t
t= 0.4 hours.
So, it takes 0.4 hours or 0.4 * 60 = 24 minutes o travel 26 miles at this speed.
