e. The population of a town growing at a constant rate each year.
PLEASE HELP!
Answers
Hey there mate :)
As per question,
Options (a), (b) and (d) are correct.
Proof :-(a) The cost per visit to a community pool.
Considering x = number of visits to the pool
a = fixed cost of visit.
So, the cost per visit to the pool y will be ax
Therefore, this represents a linear function.
And
The neighborhood charges a yearly fee to use the pool.
Assuming x = number of years
a = fixed fee to use the pool
So the yearly fee to use the pool y will be ax
Therefore, this represents a linear function.
(b) The cost to attend a show at the local theater. Tickets are $12 each.
Let x = number of shows
Let the cost of one show = $12.
Now, the cost of x shows y will be 12x
So, it represents a linear function.
(d) The distance a bicyclist travels when cycling at a constant speed of 30 mph.
Assuming x= time
Speed = 30 mph.
Since the distance (y) is given as:-
Distance = Speed×time, so,
=> y = 30x
Hence, this also represents a linear function.
Hence, all correct option are proved

hope helpful~
Answer:
3 is less than y minus 2 => 3 < y - 2
Step-by-step explanation:
If an expression has an equal sign, it is called an equation.
If it has less than or greater than sign, then it is called inequality.
It is also an inequality if it has greater than or equal to or less than or equal to signs. ( ≥, ≤).
Now y minus 2 means
y - 2
Now it says 3 is less than (y-2)
So we get
3 < y - 2

the line with a slope of 9/7 & containing a midpoint of the segment whose end points are (2, -3) & (-6, 5)
Answers
1. Find the midpoint of the segment using the midpoint formula:
Midpoint = ((x1 + x2) / 2, (y1 + y2) / 2)
Midpoint = ((2 + (-6)) / 2, (-3 + 5) / 2)
Midpoint = (-4 / 2, 2 / 2)
Midpoint = (-2, 1)
2. Use the midpoint and the slope to find the equation of the line in point-slope form. The point-slope form is given by:
y - y1 = m(x - x1), where (x1, y1) is the midpoint and m is the slope.
Substituting the values:
y - 1 = (9/7)(x - (-2))
y - 1 = (9/7)(x + 2)
y - 1 = (9/7)x + (18/7)
3. Simplify the equation to obtain the slope-intercept form:
y = (9/7)x + (18/7) + 1
y = (9/7)x + (18/7) + (7/7)
y = (9/7)x + (25/7)
So, the equation of the line with a slope of 9/7 and containing the midpoint of the segment with endpoints (2, -3) and (-6, 5) is y = (9/7)x + (25/7).
Answer:Therefore, the equation of the line with a slope of 9/7 and containing the midpoint of the line segment with endpoints (2, -3) and (-6, 5) is:
y = (9/7)x + 25/7.
Step-by-step explanation:Step 1: Find the midpoint of the line segment.
The midpoint formula is given by:
Midpoint = ((x1 + x2) / 2, (y1 + y2) / 2)
Given the endpoints of the line segment as (2, -3) and (-6, 5), we can find the midpoint as follows:
Midpoint = ((2 + (-6)) / 2, (-3 + 5) / 2)
Midpoint = (-4 / 2, 2 / 2)
Midpoint = (-2, 1)
So, the midpoint of the line segment is (-2, 1).
Step 2: Write the equation of the line using the slope-intercept form.
The slope-intercept form of a line is given by:
y = mx + b
where m is the slope and b is the y-intercept.
Given the slope as 9/7, we have:
y = (9/7)x + b
Step 3: Substitute the coordinates of the midpoint to find the value of b.
Using the coordinates of the midpoint (-2, 1), we can substitute these values into the equation:
1 = (9/7)(-2) + b
1 = -18/7 + b
To find the value of b, we can solve this equation:
1 + 18/7 = b
25/7 = b
Step 4: Write the final equation of the line.
Using the value of b, the equation becomes:
y = (9/7)x + 25/7

Felix is slicing a tortilla Española (Spanish omelet) by cutting diameters through the center. He plans on cutting 1 to 8 diameters. The number of slices is a function of the number of diameters. Describe the domain and range of the function.
Answers
The function from which the number of slices can be found based on the number of diameters, can be obtained from the function, f(n) = 2·n, which indicates;
The domain = [1, 8]
The range = [2, 16]
What is the domain and range of a function?The domain is the set of the possible input of the function, while the range is the set of possible output of the function.
The number of diameters Felix plans to slice into the tortilla = 1 to 8
The number of arcs formed by a diameters of a circle = 2
The number of arcs formed by 8 diameters = 2 × 8
Therefore, the number of arcs formed by n diameters of a circle = 2·n
Each arc of the tortilla represents a slice, therefore:
The number of slices formed by n diameters = 2·n slices
The function of the number of slices Felix gets from cutting n number of diameters is; f(n) = 2·n
The domain is the possible number of inputs, which is the number of diameters, therefore;
The domain is; 1 ≤ n ≤ 8When n = 1, f(n) = f(1) = 2 × 1 = 2
When n = 8, f(8) = 2 × 8 = 16
The range is the possible number of slices obtained from the tortilla, therefore;
The range is; 2 ≤ f(n) ≤ 16Learn more about the domain and range of a function here:

In a large population, 69 % of the people have been vaccinated. If 3 people are randomly selected, what is the probability that AT LEAST ONE of them has been vaccinated?
Give your answer as a decimal (to at least 3 places) or fraction.
Answers
The required probability is 0.970 (approx.) or 97/100 (in fraction).
Given that 69% of people in a large population have been vaccinated. We are required to determine the probability of at least one person being vaccinated if three people are randomly selected. Let's solve it using the complement rule.
The complement rule states that the probability of an event occurring is equal to 1 minus the probability of that event not occurring. That is, if A is an event, then P(A) = 1 - P(A').
We can solve the given problem using the complement rule as follows: Let P(A) be the probability of at least one person being vaccinated.
Then, the probability of no one being vaccinated is P(A') = (100 - 69) = 31%.
To find the probability of at least one person being vaccinated, we can subtract the probability of none of them being vaccinated from 1. That is, P(A) = 1 - P(A') = 1 - 0.31 × 0.31 × 0.31 = 1 - 0.029791 = 0.97021.
Hence, the probability of at least one person being vaccinated if three people are randomly selected is 0.97021 (rounded to 3 decimal places).
Therefore, the required probability is 0.970 (approx.) or 97/100 (in fraction).

For which of the following displays of data is it not possible to find the mean histogram frequency, table, stem, and leaf plot doc plot
Answers
The mean from a Histogram, table, and dot plot, it is not possible to determine the mean directly from a stem-and-leaf plot.
Out of the given options, the display of data for which it is not possible to find the mean is the stem-and-leaf plot.
A histogram displays data in the form of bars, where the height of each bar represents the frequency of data within a specific range. From a histogram, it is possible to calculate the mean by summing up the products of each value with its corresponding frequency and dividing it by the total number of data points.
A table presents data in a structured format, typically with rows and columns, allowing for easy calculation of the mean. By adding up all the values and dividing by the total number of values, the mean can be obtained from a table.
A stem-and-leaf plot organizes data by splitting each value into a stem (the first digit or digits) and a leaf (the last digit). While a stem-and-leaf plot provides a visual representation of the data, it does not directly provide the frequency or count of each value. Hence, it is not possible to determine the mean directly from a stem-and-leaf plot without additional information.
A dot plot represents data using dots along a number line, with each dot representing an occurrence of a value. Similar to a histogram and table, a dot plot allows for the calculation of the mean by summing up the values and dividing by the total number of data points.
In summary, while it is possible to find the mean from a histogram, table, and dot plot, it is not possible to determine the mean directly from a stem-and-leaf plot.
