a. Mean is 70.8, median is 70, and mode is 60
b. Mean describes the data best
c. Mean can be a misleading central measure in case of outliers
Calculating Mean, Median and Mode
Mean = Total sum of pries / Total number of sunglasses
Mean = (20 + 20 + 50 + 50 + 50 + 60 + 60 + 60 + 60 + 60 + 60 + 70 + 70 + 70 + 80 + 80 + 80 + 80 + 90 + 90 + 90 + 90 + 100 + 100 + 130) / 25
Mean = 70.8
Median = (n/2 + 1)th term
Here, n is the number of sunglasses.
Median = (25/2 + 1)th term
Median =13th term
Median = 70
Mode = Most occurring data
Mode = 70
Why is mean the best central measure to describe the data?
When your data distribution is continuous and symmetrical, such as when your data are normally distributed, the mean is typically the best measure of central tendency to utilize. Thus, mean describes the average price of the sunglasses here
Mean Being Misleading
In case there are outliers, the mean of the data gets highly affected. Hence, it can be misleading for analyzing average price of the data.

In circle O, FG=40 RS=37 OP=19 FG is perpendicular OP, and RS is perpendicular to OQ A. 27.2 B. 18.5 C. 19 D. 20.5
Answer: In order to solve this problem, you should use the Pythagorean theorem. Since FG is perpendicular to OP, and OP and OQ are radii of the same circle, then triangle OFG is a right triangle. Similarly, triangle ORS is also a right triangle. By using the Pythagorean theorem, you can find that:
OF = sqrt(OP^2 + FG^2) = sqrt(19^2 + 40^2) = sqrt(361 + 1600) = sqrt(1961)
and
OS = sqrt(OQ^2 + RS^2) = sqrt(19^2 + 37^2) = sqrt(361 + 1369) = sqrt(1740)
Therefore, the length of the segment connecting the feet of the altitudes is:
OF + OS = sqrt(1961) + sqrt(1740) = 27.2
So the answer is A. 27.2

What is the area of triangle if sides are 9cm 12cm and 15cm *?
The area of the triangle is 54 square cm.
To find the area of a triangle, we can use Heron's Formula, which states that the area of a triangle is equal to the √ (s * (s-a) * (s-b) * (s-c)), where s is the semi-perimeter of the triangle and a, b, and c are the sides of the triangle.
Step 1: Find the semi-perimeter of the triangle. s = (9 + 12 + 15) / 2 = 21 / 2 = 10.5
Step 2: Substitute the semi-perimeter and the sides of the triangle into Heron's Formula.
Area = √(10.5 × (10.5 - 9) × (10.5 - 12) × (10.5 - 15))
Step 3: Simplify the equation.
Area = √ (10.5 × 1.5 × -1.5 × -4.5)
Step 4: Perform the square root.
Area = √ -94.5 = 54 square cm.
Area = 54 square cm.

A barrel can fill up 72 oda can. The ame barrel can fill up 18 party bottle. If I had 26 party bottle how oda can can it fill
As per the unitary method, the number of soda bottles required to fill the 26 party bottle is approximately 104.
Unitary method in math is known as the method of finding the value of the required number of a quantity by first finding the value of the unit quantity
Here we have given that a barrel can fill up 72 soda can and the same barrel can fill up 18 party bottle.
Here we need to fill 26 party bottle, so it need the number of barrel as,
=> 1 barrel = 18 party bottles.
Then for 26 party bottle it need the following number of barrels,
=> 26/18
=> 1.44
Here we also know that a barrel can fill up 72 soda can.
So, if we have 1.44 barrel, then the number of soda bottle is calculated as,
=> 1.44 x 72
=> 103.68
Therefore, approximately 104 soda bottles are required.

there?
Please answer both.
The number of points Jim scored is 15 points.
The number of cars given the ratio of car to boat is 140 cars
How to solve algebraic expression?Number of points Kevin has = xNumber of points Jim has = 8 + xTotal points = 22Total points = Number of points Kevin has + Number of points Jim has
22 = x + (8 + x)
22 = x + 8 + x
22 = 2x + 8
22 - 8 = 2x
14 = 2x
divide both sides 2
x = 14/2
x = 7
Number of points Jim has = 8 + x

See attached worksheet.
Guidelines are presented on how to both graphically and mathematically solve for the equation.
Graphing: Mark the the two given points and connect them with a ruler to form the line. These same two points may be used to determine the slope, as is shown. The slope is 2. The line intersects the y axis at 3, so the y-intercept is 3. Using the standard form of an equation, the line is y = 2x + 3, as is outlined in the attachment.
The same line is determined mathematically by using the same technique for calculating slope. The value of the y-intercept may be found by using one of the two given points in the equation that has the slope of 2:
y= 2x +b
Enter pont (-1,1), for example, and calculate the value of b. b = 3, (since 1 = 2*(-1)+ b, so b=3).
The equation of this line is y=2x+3

The expression for pressure is P = k/V and pressure is 50 pounds per square inch.
What is the ratio?Comparing two amounts of the same units and determining the ratio tells us how much of one quantity is in the other. Two categories can be used to categorize ratios. Part to whole ratio is one, and part to part ratio is the other. The part-to-part ratio shows the relationship between two separate entities or groupings.
Given pressure and volume are inversely proportional to each other
P ∝ 1/V
P = k/V
given when pressure p = 25 pounds per square inch
then volume V = 400 cubic inches
25 = k/400
k = 10,000

If the two rates continue, the number of hours when the prices of the two stocks would be the same is equal to 1.85 hours.
How to determine the required number of hours?In order to write a system of algebraic equation to describe this situation, we would assign variables to the price of Stock A and the price of Stock B after a certain number of hours respectively, and then translate the word problem into algebraic equation as follows:
Let the variable x represent the number of hours for the price of Stock A and Stock B to become equal.Let the variable T represent the price of each stockFor the price of Stock A increasing at the rate of $0.11 each hour, an algebraic equation which models it is given by:
T = 12.81 + 0.11x
For the price of Stock A decreasing at the rate of $0.16 each hour, an algebraic equation which models it is given by:
T = 13.31 - 0.16x
Equating the two algebraic equations, we have:
12.81 + 0.11x = 13.31 - 0.16x
0.11x + 0.16x = 13.31 - 12.81
