What are mean, median, and mode?The three main methods for identifying the average value of a set of integers are mean, median, and mode.
Adding the numbers together and dividing the result by the total number of numbers in the list yields the arithmetic mean.
The middle value in a list that is arranged from smallest to greatest is called the median.
The value that appears the most frequently on the list is the mode.
The given data is symmetrical as we can write the no. of students from start or end it will represent the same.

Answer:
rectangles 1 and 2 are similar
Step-by-step explanation:
Polygons are similar when ...
corresponding angles are congruentcorresponding sides are proportionalIn a rectangle, all angles are 90°, so all angles are congruent.
The question of proportionality can be answered a couple of ways. One is to identify corresponding sides in the different figures, then see if the ratios between figures are the same.
Another way is to identify corresponding sides in the same figure, find their ratios, then see if those match with the ratios in the other figure.
For triangles and parallelograms, it can be useful to use the ratios of the sides in order from shortest to longest.
Here, the ratios are ...
rectangle 1: 5 : 6
rectangle 2: 7.5 : 9 = 15 : 18 = 5 : 6 . . . . similar to rectangle 1
rectangle 3: 12 : 15 = 4 : 5 . . . . not similar to the others
Rectangles 1 and 2 are similar.
_____
Additional comment
Ratios are equivalent if all the numbers involved have the same factor. For rectangle 2, we wanted to reduce the ratio to the lowest integer terms. Here, we recognize that 7.5 can be cleared of a decimal by multiplying by 2, so we did ...
7.5 : 9 = (2)(7.5) : (2)(9) = 15 : 18
Now, we can see that these numbers have 3 as a common factor, so we can remove that factor.
(3)(5) : (3)(6) = 5 : 6 . . . . reduced form of the ratio 7.5 : 9.
__
We can also get there by finding the greatest common divisor* of 7.5 and 9. That is 1.5, so we have ...
7.5 : 9 = (1.5)(5) : (1.5)(6) = 5 : 6
__
* Euclid's algorithm for finding the GCD works with decimals or fractions as well as integers. Basically, you see if the difference is a divisor of the numbers. If it is, that is the GCD. 9 -7.5 = 1.5 is a divisor of both 7.5 and 9, so that is the GCD. (If not; the difference replaces the larger number, and the process repeats.)

A utility pole is 24 feet tall and its shadow is 45 feet long. A nearby water tower is 32 feet tall. How long is the water tower's shadow?
Answer: The tower's shadow is 60 feet long.
Step-by-step explanation:
We can use a ratio to solve this:
24/45 = 32/x
Cross multiply: (Numerator of left side times the denominator of right side, and denominator of the left side by numerator of right side.)
24x = 32(45)
24x = 1440 divide both sides by 24
x = 60

What is the volume olf the basketball the diameter is 9.5 round to mearest whole nu!mber
Answer:
143π in³
Step-by-step explanation:
A basketball has the shape of a sphere
Volume of a basketball = 4/3πr³
Diameter = 9.5 in
Radius = diameter/2
= 9.5/2
= 4.75 in
Volume of a basketball = 4/3πr³
= 4/3 * π * 4.75³
= 4/3 * π * 107.17
= (4*π*107.17) / 3
= 428.68π / 3
= 142.89π in³
Approximately
143π in³ to the nearest whole number
There is a building, if you are observing from the outside it looks like a parallelogram with one of the interior angles as 108. What will be the exterior angle that can be used for parking?
Answer:
Exterior angle to be used for parking is 72°
Step-by-step explanation:
I've attached an image of a paralelogram.
Now, we are told that from the outside it looks like a parallelogram with one of the interior angles as 108.
This means that the bigger angle internally would be 108°
Which from the attached image is angle B internally or angle D internally.
So, the interior angle observed will be either at point B or D on the parallelogram.
Now, the sum of angles on a straight line is 180°
Thus,
Internal angle D + External Angle D = 180
Or
Internal angle B + External Angle B = 180
Internal angle is 108°
Thus;
External angle for either B or D = 180 - 108 = 72°
So the exterior angle to be used for parking is 72°

The triangles are similar, so the ratios of corresponding sides are equal, that is
[tex]\frac{DF}{AC}[/tex] = [tex]\frac{EF}{BC}[/tex] , substitute values
[tex]\frac{x}{21}[/tex] = [tex]\frac{18}{27}[/tex] ( cross- multiply )

Total surface area of tringular prism

8 cm
Answer:
144 cm^2
Step-by-step explanation:
The formula for a triangle is (L x W)/2. We plug this in so our first two sides are 24 and 24 square centimeters. The top side is 10 x 4, or 40 cm. The bottom side is 8 x 4, or 32 cm. The back side is 6 x 4, or 24 cm.
24 + 24 + 40 + 32 + 24 = 144 square cm
Answer:= 144cm²
Step-by-step explanation: 4x8 =32
4x6= 24
4x10= 40
8x6=48
add 32+24+40+48 =144cm²
Solve the linear equation 29 - 3x = 5x + 5
Answer:
x = 3
Step-by-step explanation:
29 - 3x = 5x + 5
You want to have the variable of x on one side of the equation, so add 3x to both sides.
29 = 8x + 5
You want to isolate the variable of x, so subtract 5 from both sides.
24 = 8x
You want the variable x on its own, so divide both sides by 8.
3 = x
Check your answer by plugging x back into the original equation.
29 - 3(3) = 5(3) + 5
Solve.
29 - 9 = 15 + 5
20 = 20

what is the rate of change of y with respect to x for this function?
Answer:
Given the function: y=f(x) = 3x+2
when x=-2 at the beginning of the interval [-2, 5],
then;
y = 3x+2 begins at
y= 3(-2)+2 = -6+2= -4.
and
when x=5 at the end of the interval [-2, 5],
y = 3x+2 ends up at
y= 3(5)+2 = 15+2= 17.
So,
y has changed -4 to 17, which is a change of 17-(-4)= 17+4 = 21
and x has changed from -2 to 5, which is a change of 5-(-2)=5+2=7
So, the average rate of change of y with respect to x over the interval
[-2, 5] is given by ;
=
Therefore, the average rate of change y with respect to x over the interval is, 3
