What is a dot plot?A dot plot also referred to as a dot chart or stripe graph, is a sort of simple histogram-like figure used in statistics for little data sets with values falling into a number of discrete bins.
It is given that:
The bus driver made 6 stops on his way into town. No passengers exited the bus. By stop 3, there were 9 passengers on the bus
The graph is shown in the picture.
The x-axis represents the bus stops
The y-axis represents the number of passengers
From the graph point to the 13 on the y-axis and locate the related value of x on the x-axis.
The number of bus stops corresponds to 13 = 4
Thus, the number of bus stops is 4 if the bus driver made 6 stops on his way into town option (C) 4 is correct.

One of your friends gives you $10 for a charity walkathon. Another friend gives you an amount per mile. After 5 miles, you have raised $13.50 total. Write an equation that represents the amount y of money you have raised after x miles.
Answers
Another friend gives you an amount per mile -- you will to calculate this value.
After 5 miles, you have raised $13.50 total --
-- Since one friend gave you $10.00, subtract this from the $13.50 to give you the amount by walking the 5 miles
-- $10.00 - $13.50 = $3.50
-- Since you walked 5 miles, divide $3.50 by 5 to give you $0.70 per mile earned.
So, an equation that represents the amount of money earned is: y = $0.70x+$10.00.
This is in slope-intercept form; the slope is $0.70 and represents the amount of money earned per mile and the intercept is $10.00 and represents the initial amount of money that you were given.
The initial amount given is $10, this represents a constant
Now another friends is willing to give an amount which is not fixed, hence it is dependent on the amount if miles we walk
Let this variable amount be x
We have walks 5 miles in total
We have raid is 13.5 total amount
Therefore he expression to represent the total amount we have made is given as
10+5x= 13.50
Let us solve for x
subtract 10 from both sides we have
5x= 13.5-10
5x= 3.50
divide both sides by 5 we have
x = 3.5/5
x= 0.7
Hence our friend gives us $0.7 per mile

For a given input value q, the function f outputs a value r to satisfy the following equation. 11q-4=3r-6, Write a formula for f(q) in terms of q
Answers
Final answer:
To find the formula for f(q), solve the equation 11q-4=3r-6 for r. The steps include adding 6 to both sides and then dividing by 3, resulting in f(q) = (11q + 2) / 3.
Explanation:
To write a formula for f(q) in terms of q, we need to solve the equation 11q - 4 = 3r - 6 for r, the output of the function f. First, we add 6 to both sides to isolate the terms with r on the right side of the equation:
11q - 4 + 6 = 3r - 6 + 6
11q + 2 = 3r
Next, we divide both sides by 3 to solve for r:
(11q + 2) / 3 = 3r / 3
(11q + 2) / 3 = r
Therefore, the formula for f(q) is:
f(q) = (11q + 2) / 3

write the equation for the transformation of the graph of y=f(x). use the form f(x)=a(x-h)+k. 13. translated 2 units left and 7 units down. 14. translated 5 units right, 2 units up, and stretched by a factor of 3.
Answers
14) f(x) = 3 ( x - 5 ) + 2
The equations of the graph after respective transformations are;
13) f(x) = a(x + 2) - 7
14) f(x) = 3(x - 5) + 2
13) In transformations, when we translate a function to the left, it means we will add the number of units it is translated to the left to f(x).
Thus, if we translate 2 units to the left, then using the form f(x) = a(x - h) + k, we will have;
f(x) = a(x + 2) + k
This is because;
h = horizontal shift
k = the vertical shift
a = the factor of stretch.
Now, we are told that it is translated 7 units down.
Downward translation denotes subtraction. Thus, k = -7 and our final translated function is;
f(x) = a(x + 2) - 7
14) Using the same concept above;
Translation of 5 units to the left means h = -5
Also, translation of 2 units up means that k = +2
Stretching by a factor of 3 means that a = 3.
Thus, from the form; f(x) = a(x + h) + k, we have;
f(x) = 3(x - 5) + 2

what is 0.279 times 53
Answers
Final answer:
To calculate 0.279 times 53, multiply 279 by 53 and then place the decimal point three places from the right of the product, resulting in 14.787. If rounding to two decimal places, the answer is 14.79.
Explanation:
To find the product of 0.279 times 53, we can follow the usual multiplication process. We multiply as if there were no decimal places, and then we count the total number of decimal places in both numbers to place the decimal in the correct position in the final answer.
0.279 has three decimal places, and 53 has none. After you multiply 279 by 53, count three places from the right of the resulting number to place the decimal point. So, if 279 times 53 equals 14787, then 0.279 times 53 equals 14.787.
Applying the rules of rounding, if we wanted to round the result to two decimal places we would get 14.79 since the third decimal place is a 7 which rounds up the second decimal place from 8 to 9.

mary climbed up a ladder 24 feet to the second story of her house. she then climbed back down
Answers
Final answer:
To draw Mary's ascent and descent on a ladder, create a vertical number line from 0 to 24 feet to signify the height of the second story, then illustrate arrows for the ascent and descent.
Explanation:
To visualize Mary's movement on a ladder, we will draw a vertical number line. Let's assume the bottom of the ladder is at 0 feet. We will draw a number line up to 24 feet to represent the height Mary climbs to reach the second story of her house. Then, since Mary climbed back down, we would show her descent back to 0 feet. Here is how you can draw the scenario:
Start with a vertical line.Mark the bottom as 0 feet (this is where Mary starts and finishes).Mark a point at 24 feet (this is where the second story of her house is).Draw an arrow pointing up from 0 to 24 to represent Mary climbing up.Draw an arrow pointing down from 24 back to 0 to represent Mary climbing down.By following these steps, you will have a clear representation of Mary climbing up and down her ladder on a vertical number line.
