If this problem cannot be solved with the information provided, write additional information
and then solve the problem.

She need 6 points to score in her 12th game in order to decrease the interquartile range by 1 point.

What is Interquartile range?

An Interquartile range is one of the measure of variability that measures the spread of middle 50% of the data.

Given that;

A basketball player recorded for 11 consecutive games her points as;

13, 20, 15, 22, 24, 21, 18, 20, 25, 17, 27

Now,

Since, We know that;

The formula for the interquartile range is,

⇒ IQR = Q₃ - Q₁

Where, Q₃ is the third quartile , Q₁ is the first quartile.

Here, We arrange the points in the increasing order as;

⇒ 13, 15, 17, 18, 20, 20, 21, 22, 24, 25, 27

The first quartile is calculated as;

Q₁ = (n + 1) / 4 th term

Where, n is number of terms.

Q₁ = (11 + 1) / 4

Q₁ = 3rd term

Q₁ = 17

The third quartile Q₃ is calculated as;

Q₃ = 3(n + 1) / 4

Q₃ = 3 x 3

Q₃ = 9th term

Q₃ = 24

Thus, The interquartile range is,

⇒ IQR = Q₃ - Q₁

⇒ IQR = 24 - 17

⇒ IQR = 7

So, The desired interquartile range is,

⇒ IQR = 7 - 1

⇒ IQR = 6

Therefore, She need 6 points to score in her 12th game in order to decrease the interquartile range by 1 point.

 To prove that given is perpendicular we have show that one make right angle, i.e. 90 degree.

A perpendicular is a straight line in mathematics that forms a right angle (90 degrees) with that other line. In other words, two lines become perpendicular to one another if they connect at a right angle.

For proof of perpendicular-

Theorm 1 : If two lines intersect to form a pair of lines with a "congruent angle," then the lines are perpendicular to one another. Angles that are equivalent to one another are known as congruent angles.

Theorm 2 : Four right angles will be formed if two perpendicular lines cross.

Theorm 3 : The "adjacent acute angles" are complimentary if two of their sides are perpendicular. As you presumably remember, acute angles are angles that are fewer than 90 degrees, whereas adjacent angles are angles that are next to one another.

The value of x using the Pythagoras Theorem is 6.08 cm.

What is Pythagoras' Theorem?

The relationship between the three sides of a right-angled triangle is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem. The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares. The relationship between the three sides of a right-angled triangle is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem. The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.

According to the Pythagoras theorem, the square of the hypotenuse of a triangle, which has a straight angle of 90 degrees, equals the sum of the squares of the other two sides. Look at the triangle ABC,is present. The base in this equation is AB, the height is AC, and the hypotenuse is BC.

In the given figure, we have:

A right angles triangle.

So, the Hypotenuse meaure is 14.2 cm;

The measure of the base side is 3.6 + 9.7 cm = 13.3 cm;

So, we can find the perpendicular side length using the Pythagorean Theorem

So, using the Pythagoras theorem,

[tex]c^{2} = x^{2} + y^{2}[/tex]

[tex](14.2)^{2} = (13.3)^{2} + x^{2}[/tex]

201.64 = 176.89 + [tex]x^{2}[/tex]

24.75 = [tex]x^{2}[/tex]

So, x = 4.97

So, The perpendicular side is 4.97 cm;

Now using the Pythagoras theorem again in the smaller triangle, we get:

[tex](3.6)^{2} + (4.9)^{2} = x^{2}[/tex]

12.96 + 24.01 = [tex]x^{2}[/tex]

36.97 = [tex]x^{2}[/tex]

So, The value of x is 6.08 cm;

Hence,

The value of x is 6.08 cm;.

After the subtraction, the simplified form of the mixed number is 33/4

Mixed numbers

Mixed fraction means a fraction represented with its quotient and remainder.

Given,

Here we have the mixed numbers 12 5/12 - 4 1/6

Now, we have to perform the subtraction in it and then we have to simplifies it.

Firs we have to convert the mixed numbers into normal fraction, for that we have to do the following:

12 5/12 = (12 x 12) + 5/12

=> (144 + 5)/12

=> 149/12

Similarly, when we simplifies the second one, then we get,

=> 4 1/6 = (6 x 4) + 1/6

=> (24 + 1) / 6

=> 25/6

Here the fractions have unlike denominators.

So, first we have to find the Least Common Denominator and rewrite the fractions with the common denominator.

Therefore, the LCD(149/12, 25/6) = 12

Now, we have to multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD.

=> 149/12 - 50/12

The two fractions now have like denominators so you can subtract the numerators.

Then:

=> 99/12

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 99 and 12 using GCF(99,12) = 3

Step-by-step explanation:

since it is a right-angled triangle, the principle of Pythagoras has to be fulfilled :

c² = a² + b²

c being the Hypotenuse (the side opposite of the 90° angle), which is in our case (x + 32).

a and b are the legs.

so

(x + 32)² = x² + (x + 31)²

x² + 64x + 1024 = x² + x² + 62x + 961

2x + 1024 = x² + 961

x² - 2x - 63 = 0

as 63 = 7×9

and -9 + 7 = -2

we can conclude that this quadratic equation is the same as the following factorization :

(x + 7)(x - 9) = 0

we have 2 solutions :

x = -7

x = 9

as x is also the length of a side, the negative solution does not make any sense.

so, x = 9 is our solution.

that means the sides of the triangle are

x = 9

x + 31 = 40

x + 32 = 41

and the perimeter of the triangle is

9 + 40 + 41 = 90

The vertex is (7, -27)

The line of symmetry is x = 7.

The minimum is y = -27

The domain is the set of all real numbers.

The range is y ≥ -27.

Given,

The quadratic equation is as follows:

f(x) = (x - 7)^2 - 27

The quadratic equation is in vertex form, hence if the vertex is (h, k), the vertex form will be as follows:

f(x) = (x - h)^2 + k

Then the vertex in this instance is (7, -27).

A line of the form x = h is the line of symmetry, and in this instance the line is x = 7.

The minimum of the quadratic equation is y = -27 since the function has a positive leading coefficient, indicating that the vertex is a minimum.

Finally, the domain is the set of all real numbers, much like the domain of any quadratic equation.

The range includes all real numbers that are greater than or equal to -27.

The equation that represents the proportional relationship is y=14x. The correct option is D.

Given the table which shows a proportional relationship X=1,2,3 and Y=14,28,42.

We want to find an equation that represents the proportional relationship.

We will find the proportional relationship by dividing Y with X.

When X=1 and Y=14 then proportional relationship is

Y/X=14/1

Multiply both sides by X, we get

(Y/X)X=14X

Y=14X.....(1)

When X=2 and Y=28 then proportional relationship is

Y/X=28/2

Y/X=14

Y=14X.....(2)

When X=3 and Y=42 then proportional relationship is

Y/X=42/3

Y/X=14

Y=14X......(3)

From equation (1),(2) and (3) we get that the proportional relationship is Y=14X.

A random variable can be defined as a variable whose value is unknown or as a function that assigns numerical values to each of the outcomes of an experiment. It can also be defined as a rule that assigns a numerical value to each outcome in a sample space.

The density function (1.4-5)P(x) = an exp(-ax), if x0,0, if x>0, where an is any positive real number, defines the exponential random variable.

radius R has df f(r) ={\lambdae}^{-\lambdar}

area Y= *r2

r = \pm (Y/(\pi))1/2

hence P(Y<y) =F(Y) =P( *r2<y) =P(r<+/- (Y/( ))1/2 ) = \int_{{-y/\pi}^{1/2}}^{{(y/\pi)}^{1/2}}{\lambdae}^{-\lambdar} dr

Therefore P(df of y) = f(y) = d/dyf(y) =(d/dy) (e^{{\lambda(y/\pi)}^{1/2}}- e^{{-\lambda(y/\pi)}^{1/2}})

= ½({(y/\pi)}^{1/2}(e^{{\lambda(y/\pi)}^{1/2}}+ e^{{-\lambda(y/\pi)}^{1/2}})
