3(n+11)-5n=-2(n-12)+9
The given equation simplifies to -2n + 33 = -2n + 33, where both sides are equal, hence 'n' can be any real number. Thus the equation has infinitely many solutions.
Explanation:This question pertains to solving a linear equation. The given equation is 3(n+11)-5n=-2(n-12)+9.
Let's solve this step by step:
First distribute 3 and -2 in the brackets (Order of Operations - BIDMAS/BODMAS). This will result in: 3n+33-5n = -2n + 24 + 9.Combine like terms on both sides of the equation to obtain: -2n + 33 = -2n + 33.Lastly you can see that both sides of the equation are equal, this means that n can be any real number.This indicates that we have infinitely many solutions because any value of 'n' satisfies this equation.

What is P(0.6 ≤ z ≤ 2.12)?
The value of P(0.6 ≤ z ≤ 2.12) is, 26%
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Given that;
To find the value of P(0.6 ≤ z ≤ 2.12).
Now, We can simplify as;
P(0.6 ≤ z ≤ 2.12) = P( z ≤ 2.12) - P(z < 0.6)
So, From the Cumulative Standardized Normal Distribution table,
P( z ≤ 2.12) = 0.9830
P(z < 0.6) = 0.7257
Hence, We get;
P(0.6 ≤ z ≤ 2.12) = P( z ≤ 2.12) - P(z < 0.6)
P(0.6 ≤ z ≤ 2.12) = 0.9830 - 0.7257
P(0.6 ≤ z ≤ 2.12) = 0.2573
P(0.6 ≤ z ≤ 2.12) = 0.26
P(0.6 ≤ z ≤ 2.12) = 26%
Thus, The value of P(0.6 ≤ z ≤ 2.12) is, 26%

What are the x-intercepts of the graph of the function f(x) = x2 + 5x − 36?
Answer:
x intercepts are (4,0) and (-9,0)
Step-by-step explanation:
The given function graphed f(x) = x² + 5x -36 and we have to find the x-intercepts.
Since x intercepts means points on x-axis which will have y-coordinates as zero.
so f(x) = x² + 5x - 36 = 0
x² + 9x - 4x - 36 = 0
x(x+9) - 4(x-9) = 0
(x-4)=0 ⇒ x = 4
or ( x+9) = 0 ⇒ x = (-9)
Therefore, x intercepts are (4,0) and (-9,0)
Considering the definition of function quadratic and roots, the roots or x-intercepts of the graph of the function f(x) = x² + 5x − 36 are 4 and -9.
Function quadraticThe function f(x) = ax² + bx + c
with a, b, c real numbers and a ≠ 0, is a function quadratic expressed in its polynomial form (It is so called because the function is expressed by a polynomial).
Definition of rootsThe roots are those values of x for which the expression is 0, so it graphically cuts the x-axis.
This can be solved by:
[tex]x1, x2=\frac{-b+-\sqrt{b^{2} -4ac} }{2a}[/tex]
x-intercepts of f(x) = x² + 5x − 36In this case you know that a=1, b= 5 and c= -36. So the roots can be determined as:
[tex]x1=\frac{-5+\sqrt{5^{2} -4x1x(-36)} }{2x1}[/tex]
[tex]x1=\frac{-5+\sqrt{25 +144} }{2}[/tex]
[tex]x1=\frac{-5+\sqrt{169} }{2}[/tex]
[tex]x1=\frac{-5+13}{2}[/tex]
[tex]x1=\frac{8}{2}[/tex]
x1= 4
and
[tex]x2=\frac{-5-\sqrt{5^{2} -4x1x(-36)} }{2x1}[/tex]
[tex]x2=\frac{-5-\sqrt{25 +144} }{2}[/tex]
[tex]x2=\frac{-5-\sqrt{169} }{2}[/tex]
[tex]x2=\frac{-5-13 }{2}[/tex]
[tex]x2=\frac{-18 }{2}[/tex]
x2= -9
Finally, the roots or x-intercepts of the graph of the function f(x) = x² + 5x − 36 are 4 and -9.

A gardener uses a tray of 6 conical pots to plant seeds. Each conical pot has a radius of 3 centimeters and a depth of 8 centimeters. About how many cubic centimeters of soil are needed to plant the full tray? Round to the nearest cubic centimeter.
By definition, the volume of a cone is given by:
[tex] V = (\frac{1}{3}) * (\pi) * (r ^ 2) * (h)
[/tex]
Where,
r: radius of the circular base
h: height of the cone
Since we have 6 conical pots, then the total volume is:
[tex]Vt=6V[/tex]
[tex] Vt = 6 * (\frac{1}{3}) * (\pi) * (r ^ 2) * (h)
[/tex]
Substituting values we have:
[tex] Vt = 6 * (\frac{1}{3}) * (3.14) * (3 ^ 2) * (8)
Vt = 452.16 cm ^ 3
[/tex]
Rounding to the nearest cubic centimeter:
[tex] Vt = 452 cm ^ 3
[/tex]
Answer:
are needed 452 cm^3 of soil to plant the full tray
The cubic centimeters of soil are needed to plant the full tray is approximately 452cubic in
Volume of a coneThe formula for calculating the volume of a cone is expressed as:
V = 1/3πr²h
r is the radius = 3cm
h is the height = 8cm
Substitute
V = 1/3 * 3.14 * 3^2 * 8
V = 75.36 cubic cm
Since the gardener uses a tray of 6 conical pots to plant seeds, the total volume will be expressed as:
T = 6(75.36)
T = 452cubic in
Hence the cubic centimeters of soil are needed to plant the full tray is approximately 452cubic in
