Answer:
Okay so your numbers are:
0, 2, 2, 4, 5, 1, 3, 4, 2, 4, 5, 0, 0, 1, 3, 4
You have to put them in order first:
0, 0, 0, 1, 1, 2, 2, 2, 3, 3, 4, 4, 4, 4, 5, 5
Now that its all in order you have to pull out the middle number.
Since there are 16 numbers its an even pile so you have to get the 2 middle numbers:
2, 3
Add them both together:
2 + 3 = 5
Then divide by 2:
5 ÷ 2
= 2.5

A rectangular garden 50 m long by 34 m wide is surrounded by a sand path of uniform width. Calculate the width of this path if it is known that it has an area of 540 cm2.
Considering a width x of the sand path, we have a larger rectangle of dimensions 50+2x by 34+2x, as indicated in the figure. Now, the area of the sand path is expressed.
[tex]\boldsymbol{\sf{ (50+2x)(34+2x)-50\times 34=540\Longrightarrow\quad 0=4x^2+168x-540 }}[/tex]
[tex]\boldsymbol{\sf{ 0=4(x^2+42x-135)=4(x-3)(x+45) }}[/tex]
Therefore, the path is 3 m long.

Determine the equation of the circle graphed below.
The standard equation of the circle in the graph is (x - 2)² + (y - 5)² = 16
How to determine the standard equation?From the graph, we have the following parameters:
Center (a,b) = (2,5)Radius, r = 4The equation of the circle is then calculated using:
(x - a)² + (y - b)² = r²
So, we have:
(x - 2)² + (y - 5)² = 4²
Evaluate
(x - 2)² + (y - 5)² = 16
Hence, the standard equation of the circle in the graph is (x - 2)² + (y - 5)² = 16

We know the compound interest formula.
A = P (1 + r)ⁿ
We have
P = $ 400
r = 13%
n = 7 years
Then we have
A = 400 x (1 + 0.13)⁷
A = 400 x 1.13⁷

Which lines are perpendicular to 3x – y = 10? Select all that apply. A. y = 3x + 5 B. y = –13x + 17 C. x + 3y = 27 D. y – 2 = 13(3x + 36)
The equation of the line which is perpendicular to 3x - y = 10 is y = -(1/3) x + c. Then the correct option is B.
What is the linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
The line that is perpendicular to 3x - y = 10.
The equation can be written as
y = 3x - 10
Then the slope of the line will be
m₁ = 3
Let m₂ be the slope of the second line.
The product of the slope of the perpendicular lines is a negative one.
m₁m₂ = -1
3m₂ = -1
m₂ = -1/3
Then the equation of the perpendicular line will be
y = - (1/3)x + c
3y = -x + c
x + 3y = c
where c is the constant.
Thus, the correct option is B.
