If she priced scooter for $15.50 and ended up selling it for $10.75, then the percentage of decrease in the price of the scooter is 30.64%
The initial price of the scooter = $15.50
The selling price of the scooter = $10.75
The amount decrease in the price of the scooter = Initial price of the scooter - The selling price of the scooter
= 15.50-10.75
= $4.75
The percent of decrease in the price of the scooter = (The amount decrease in the price of the scooter ÷ The initial price of the scooter)×100
= (4.75/15.50)×100
= 30.64%
Hence, if she priced scooter for $15.50 and ended up selling it for $10.75. then the percentage of decrease in the price of the scooter is 30.64%

Construct a perpendicular bisector to AB
Step-by-step explanation:
In order to construct a perpendicular from a point to a given line segment: Draw two arcs crossing the line segment. Make two more arcs which intersect. Join the point where the arcs intersect to the original point.
Events A and B are mutually exclusive. Suppose event A occurs with probability 0.23 and event B occurs with probability 0.21.
a. Compute the probability that A occurs but B does not occur.
b. Compute the probability that either A occurs without B occurring or B occurs without A occurring.
Using it's concept, the probabilities for this problem are given as follows:
a) A occurs and B does not: 0.1817 = 18.17%.
b) Either occurs: 0.3434 = 34.34%.
What is a probability?A probability is calculated as the number of desired outcomes in the experiment divided by the number of total outcomes in the experiment.
In the context of this problem, we have two mutually exclusive events, meaning that they cannot happen together.
For item a, we have that:
The probability of A occurring is 0.23.The probability of B not occurring is of 1 - 0.21 = 0.79.The events are mutually exclusive, hence we can multiply the probabilities as follows:
p = 0.23 x 0.79 = 0.1817 = 18.17%.
For item b, we add the probability in item with the probability of B occurring and A not, found as follows:
The probability of B occurring is 0.21.The probability of A not occurring is of 1 - 0.23 = 0.77.Hence:
p = 0.1817 + 0.21 x 0.77 = 0.3434 = 34.34%.

The. median, range, and mode for the following numbers:8,7,12,7,11,10,7,12
Answer:
median = 9
range = 5
mode = 7
Step-by-step explanation:
median = 9 is in the middle of 10 and 8
range = 12 - 7
mode = there are 3 7s
Mode : the quantity that appears the most in a sequence
Because 7 is the number that appears the most ( 3 times ), it is the mode.
Range : the difference between the largest number and the smallest number
In this case, 12 is the biggest and 7 is the smallest -> Range = 5.
Median : the "middle number" (for example, if the sequence has 7 numbers, the 4th number will be the median. if the sequence has 8 numbers, the median will be the average of the 4th and 5th number, and of course from increasing order.)
There are 8 numbers in the sequence, from lowest to highest : 7,7,7,8,10,11,12,12.
So, the median = (8+10)/2 = 9.

The equation shown has a missing value.
-2(2x - _) + 1 = 17 - 4x
For what missing value(s), if any, does the equation have exactly one solution?
There is no value for which the missing place should be filled in order to have exactly one solution.
A Linear equation may be defined as the one which can be represented in the form ax + b = 0 where a, b are coefficients and x is the independent variable. Since the equation only has one variable that is x then the linear equation will be rightly called as linear equation in one variable. We are given the equation -2(2x - _) + 1 = 17 - 4x. We solve the equation further which results as
-4x - _ + 1 = 17 - 4x
As we can see that there is -4 in both the right-hand side as well as the left-hand side both of them gets cancelled out.
- _ +1 = 17
As we can see that there is no variable left in order to find the value so any value of missing space will not be able to give any solution.

5. Write two equivalent equations for a line with x-intercept (3,0) and y-intercept (0, 2).
The equation of the first line is y = -1/3x - 4, while the equivalent equations of the second line are y = -2/3(x - 3) and y = -2/3x + 2
How to determine the equation of the line?The given parameters are
Slope, m = 5/4
Point, (x1, y1) = (1, 3)
A linear equation is represented as
y = m(x - x1) + y1
So, we have
y = 5/4(x - 1) + 3
This gives
y = 5/4x + 7/4
Hence. the linear equation is y = 5/4x + 7/4
The equivalent equationsHere, we have
(x, y) = (3, 0) and (0, 2)
A linear equation is represented as
y = m(x - x1) + y1
Where
m = (y2 - y1)/(x2 - x1)
So, we have
m = (2 - 0)/(0 - 3)
m = -2/3
So, we have
y = -2/3(x - 3)
The above equation can be rewritten as
y = -2/3x + 2
Hence, the equations are y = -2/3(x - 3) and y = -2/3x + 2

What is a square?A square is a kind of a 2D figure in which all the sides are equal.
We know that the absolute perimeter of a square is the sum of the lengths of all the total sides and as we see the area of a square is (side)².
Assuming that the whole square has four units completed for each side.
The square's circumference can be calculated as is 4 sides plus 4 fours, or as seen as 16 units.
Now the area of the square will be calculated as (4) ² = 16 sq units.
Now assuming that the total side length of the square about is 2 units.
The square's perimeter is calculated as (24) = 8 units, while its total area is calculated as (22) = 4 units.
∴ 2 units make up the side length that serves as a counterexample.

The volume of the figure shown in the reference attachment, provided hereby with the question statement will be 6786 ft³.
As per the question statement and the reference attachment, we are provided with a figure and its dimensions.
We are required to calculate the volume of the concerned figure using the dimensional values provided.
To solve this question, we need to calculate the volumes of the bottom cuboidal part, and the top pyramidal part separately, and then add these volumes, to obtain our final desired answer.
Given, the dimensions of the bottom cuboidal part is (21ft by 18ft by 13ft).
We know that, volume of a cuboid = (length * breadth * height).
Therefore, volume of our concerned bottom cuboidal part
= (21 * 18 * 13) ft³
= 4914 ft³.
Also given, the dimensions of the top pyramidal part are as follows,
Base of the triangle = 18 ft,
Altitude of the triangle = 16 ft,
and length of the pyramid = 13 ft.
Therefore, Volume of the concerned pyramid
= [(1/2) * base * altitude * length]
= [(1/2) * 18 * 16 * 13] ft³
= (9 * 16 * 13) ft³
= 1872 ft³.
Therefore, Total volume of the concerned figure shown in the reference attachment, provided hereby with the question statement will be
(4914 + 1872) ft³ = 6786 ft³

two carts, a and b, are connected by a rope 39 ft long that passes over a pulley p. the point q is on the floor 12 ft directly beneath p and between the carts. cart a is being pulled away from q at a speed of 2 ft/s. how fast (in ft/s) is cart b moving toward q at the instant when cart a is 5 ft from q? (round your answer to two decimal places.)
The velocity of the cart b is found as 20/23 ft/s over the pulley.
What is defined as the rate of change?The momentum of a variable is represented by the rate of change, which is used to mathematically define the percentage change in value over such a defined period of time.For the given data in the question.
q's velocity is 2 feet per second.
Rope length is 39 feet.
Assume x is the distance between A and Q. (refer the image).
Assume y is the distance between Q and B. (refer the image).
As a result of the image,
x² + 12² = L²
Now, with respect to time t, differentiate the above equation.
2x(dx/dt) + 0 = 2L.(dL/dt)
For x = 5 ft and L = 13 ft
dL/dt = (5×2)/13 = 10/13
In the case of B,
y² + 12² = (39 - L)² ; from diagram.
Differentiating now,
2y(dy/dt) + 0 = -2(39 - L).(dL/dt)
At x = 5 ft and y = 23 ft.
dy/dy = -20/23
(A negative sign indicates the opposite direction)
Thus, the velocity of cart b is found as 20/23 ft/s.
