SOLUTIONSince a perimeter is a total distance around the figure.
And a square is a quadrilateral(with four sides) which are equal.To find the length of each side,divide the perimeter by 4.
60 cm÷4 = 15 cmSince,Area of square = side×side = 15cm×15cm = 225cm^2hope it helps you.
Answer:
Area of square = 225 cm²
Step-by-step explanation:
Perimeter of square formula,
→ P = 4 × side
→ P = 4a
Now the side of square will be,
→ P = 4a
→ 4a = 60
→ a = 60/4
→ [ a = 15 cm ]
Then the area of square will be,
→ (a)²
→ (15)²
→ 225 cm²
Hence, area of square is 225 cm².
Verify that if Y has a beta distribution withα=β=1then Y has a uniform distribution over (0, 1). That is, the uniform distribution over the interval (0, 1) is a special case of a beta distribution.
The standard uniform distribution is a special case of the beta distribution when β = γ = 1.
A sort of probability distribution called the beta distribution encompasses all potential probabilities. With examples, let's go over its definition and formula. The Beta distribution is a continuous probability distribution that is defined by two positive parameters in probability and statistics. It is a kind of probability distribution that is used to depict the results or irrational behavior of percentages or proportions.
Let the random variable X ∼ beta(β, γ). The probability density function of X is mentioned in the picture given below which is the probability density function of a standard uniform random variable.

What is function?function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable) (the dependent variable) (the dependent variable). Mathematics uses functions frequently, and functions are essential for specifying physical relationships in the sciences.
Here,
The function is given as:
f(x,y,z)=[tex]x^{2} y^{2} z^{2}[/tex]
[tex]x^{2} +y^{2}+ z^{2}[/tex]=1
=>[tex]x^{2} +y^{2}+ z^{2}[/tex]-1=0
Using Lagrange multiplies, we have:
L(x,y,z,λ)=f(x,y,z) +λ(0)
Substitute f(x,y,z)=[tex]x^{2} y^{2} z^{2}[/tex] and [tex]x^{2} +y^{2}+ z^{2}[/tex]-1=0
Differentiate
L(x)=[tex]2xy^{2} z^{2}[/tex]+2λx
L(y)=[tex]2yx^{2} z^{2}[/tex]+2λy
L(z)=[tex]2zx^{2} y^{2}[/tex]+2λz
L(λ)=[tex]x^{2} +y^{2}+ z^{2}[/tex]-1
Equating to 0
[tex]2xy^{2} z^{2}[/tex]+2λx =0
[tex]2yx^{2} z^{2}[/tex]+2λy = 0
[tex]2zx^{2} y^{2}[/tex]+2λz = 0
[tex]x^{2} +y^{2}+ z^{2}[/tex]-1 = 0
Factorize the above expressions
[tex]2xy^{2} z^{2}[/tex]+2λx =0
2x([tex]y^{2} z^{2}[/tex]+λ)=0
2x=0 and ([tex]y^{2} z^{2}[/tex]+λ)=0
x=0 and [tex]y^{2} z^{2}[/tex]= -λ
[tex]2yx^{2} z^{2}[/tex]+2λy = 0
2y([tex]x^{2} z^{2}[/tex]+λ)=0
2y=0 and ([tex]x^{2} z^{2}[/tex]+λ)=0
y=0 and [tex]x^{2} z^{2}[/tex]= -λ
[tex]2zx^{2} y^{2}[/tex]+2λz = 0
2z([tex]y^{2} x^{2}[/tex]+λ)=0
2z=0 and ([tex]x^{2} y^{2}[/tex]+λ)=0
z=0 and [tex]x^{2} y^{2}[/tex]= -λ
So we have ,
x=0 and [tex]y^{2} z^{2}[/tex]= -λ
y=0 and [tex]x^{2} z^{2}[/tex]= -λ
z=0 and [tex]x^{2} y^{2}[/tex]= -λ
The above expression becomes
x=y=z=0
This means that,
[tex]x^{2} +y^{2}+ z^{2}[/tex]=1
[tex]x^{2} +x^{2}+ x^{2} =1 \\3x^{2 } =1[/tex]
x= ±1/[tex]\sqrt{3}[/tex]
So,
y= ±1/[tex]\sqrt{3}[/tex]
z= ±1/[tex]\sqrt{3}[/tex]
The critic points are
x=y=z=±1/[tex]\sqrt{3}[/tex]
x=y=z=0
Therefore the maximum value of function f(x,y,z)=[tex]x^{2} y^{2} z^{2}[/tex] =1/27
And the minimum value is 0

What is the equation of the line that passes through the point (6,2) and has a slope of 1/3 ?
The equation of the line passes through the point (6,2) and slope 1/3 is
X=3Y-3
Here the point is (6,2) and the slope is 1/3
Means,
x=6 y=2 and m=1/3
We know that the equation of a line is -
Y=mx+c
Putting these values in the above equation we get
⇒2=1/3×6+c
⇒2=6/3+c
⇒2=2+c
⇒c=1
Therefore we find that the intercept is 1
So after putting all these values in that equation y=mx+c we get
Y=1/3X+1
⇒X/3=Y-1
⇒X=3Y-3
The equation passes through the point (6,2) and the slope is 1/3 is x=3y-3

Select all true statements about quadrilateral JKLO.
1.) When JKLO is reflected across segment OA, JKLO is taken to HGLO. So, quadrilateral JKLO is congruent to quadrilateral HGLO.
2.) When JKLO is reflected across segment OJ, JKLO is taken to JIHO. So, quadrilateral JKLO is congruent to quadrilateral JIHO.
3.) When JKLO is reflected in any way, it will not produce another congruent quadrilateral in this figure. However, there is a way to translate JKLO to take it to another quadrilateral in this figure.
4.) When JKLO is reflected across segment OI, JKLO is taken to JIHO. So, quadrilateral JKLO is congruent to quadrilateral JIHO.
5.) When JKLO is reflected across segment OL, JKLO is taken to HGLO. So, quadrilateral JKLO is congruent to quadrilateral HGLO.
The statement 2) and 5) about the construction are correct.
What is construction?In geometry, the term "construction" refers to precisely drawing forms, angles, or lines. These structures simply require a pencil, compass, and straightedge (a ruler).
Given this, a design was created by building a standard hexagon.
The construction's real claims are as follows:
2) JKLO is taken to JIHO when it is mirrored across segment OJ. Therefore, quadrilateral JKLO and quadrilateral JIHO are congruent.
5) JKLO is transferred to HGLO when it is reflected over segment OL. Therefore, quadrilateral JKLO and quadrilateral HGLO are congruent.

Kusum bought 50 glasses for rs 1500 out of which 4 were broken if she sold the rest of the glasses for rs 35 each how many profit or loss percent did she bear
Answer:
7.3%
Step-by-step explanation:
Cost for 50 glasses = ₹1500 -----> Cost Price (C.P)
Cost per glass = 1500/50 = ₹30
Here, 4 glasses break. So, she now has
50-4 = 46 glasses
She sold 46 glasses for ₹35 each,
Money earned = 46x35 = ₹1610 -----> Selling Price (S.P)
Since S.P > C.P,
she made a profit = 1610-1500 = ₹110
Profit% = Profit/Cost Price x 100
= 110/1500 x 100
= 7.3%

a certain acid has a ka equal to 5.57 x 10-5. determine the pkb of its conjugate base (give your answer to two decimal places)
The pk[tex]_b[/tex] of given acid conjugate base is 9.74 if k[tex]_a[/tex] of the same acid is equal to 5.57×10⁻⁵
The Bronsted-Lowry corrosive base hypothesis incorporates the ideas of form acids and form bases. At the point when a corrosive separates into its particles in water, it loses a hydrogen particle. The species that is shaped is the corrosive's form base.
A more broad definition is that a form base is the base part, X-, of a couple of mixtures that change into one another by acquiring or losing a proton. The form base can acquire or retain a proton in a synthetic response. The form corrosive gives the proton or hydrogen in the response.
In a corrosive base response, the substance response is:
Corrosive + Base ⇌ Form Base + Form Corrosive
We know very well that from equilibrium state theories that pk[tex]_b[/tex] +pk[tex]_a[/tex] =14
where pk[tex]_a[/tex] = - log( k[tex]_a[/tex] )
So, we have k[tex]_a[/tex] =5.57×10⁻⁵
Taking log of k[tex]_a[/tex] ,we get
=>pk[tex]_a[/tex]= -log(5.57×10⁻⁵)
Using properties of logarithm, log(a × b)=log(a)+log(b)
=>pk[tex]_a[/tex]= -log(5.57) -log(10⁻⁵)
=>pk[tex]_a[/tex]= -0.745 +5
=>pk[tex]_a[/tex]=4.25
Therefore, from above written formula, we get
=>4.25+pk[tex]_b[/tex]=14
=>pk[tex]_b[/tex]=14-4.25
=>pk[tex]_b[/tex]=9.74
Hence, pk[tex]_b[/tex] value is 9.74

What influences how the temperature fluctuates?The balance between energy coming into and going out of the planet's system determines its temperature. The Earth warms up when incoming solar energy is absorbed by the Earth system. Earth does not warm as a result of solar energy being reflected back into space. Earth cools as energy that has been absorbed is ejected back into space.Since 1880, the Earth's average temperature has increased by 0.14° F (0.08° C) every decade; however, since 1981, the pace of warming has increased by 0.32° F (0.18° C) per decade, or more than twice as fast.

Work out the size of angle 0.
Give reasons for your answer.
Answer:
θ = 56°
Step-by-step explanation:
As OA and OB are both radii, triangle AOB is an isosceles triangle:
⇒ m∠ABO = m∠OAB = 48°
Interior angles of a triangle sum to 180°:
⇒ m∠ABO + m∠OAB + m∠AOB = 180°
⇒ 48° + 48° + m∠AOB = 180°
⇒ m∠AOB = 180° - 48° - 48°
⇒ m∠AOB = 84°
Angles on a straight line sum to 180°:
⇒ m∠AOB + m∠DOB = 180°
⇒ 84° + m∠DOB = 180°
⇒ m∠DOB = 180° - 84°
⇒ m∠DOB = 96°
The tangent of a circle is always perpendicular to the radius.
Therefore, tangent BC is perpendicular to radius OB, and tangent DE is perpendicular to radius OD, so:
m∠OBC = 90°m∠ODE = 90°OBCD is a quadrilateral.
The interior angles of a quadrilateral sum to 360°:
⇒ m∠OBC + m∠BCD + m∠CDO + m∠DOB = 360°
⇒ 90° + θ + 28° + 90° + 96° = 360°
⇒ θ + 304° = 360°
⇒ θ = 360° - 304°
⇒ θ = 56°
