The interquartile range of the concert tickets sold is 72. (the second option).

A box plot is a graph that is used to study the distribution and level of a set of scores. The box plot consists of two whiskers and a box. The first whisker represents the minimum number and the end of the second whisker represents the maximum number.

On the box, the first line to the left represents the lower (first) quartile. The next line on the box represents the median. The third line on the box represents the upper (third) quartile.

The interquartile range is the difference between the third quartile and the first quartile.

Interquartile range =  third quartile - first quartile

369 - 297 = 72

The number of ways that they can share these fruits if each person must have at least 1 fruit will be 12 ways.

From the information, 6 apples and 5 oranges are shared among 3 people and the apples are indistinguiable, oranges are also indistinguiable.

Therefore, the number of ways that they can share these fruits if each person must have at least 1 fruit will be:

= (6 - 3)! × (5 - 3)!

= 3! × 2!

= 3 × 2 × 2

= 12

If [tex]\hat\gamma-c\hat\alpha-d\hat\beta[/tex] is perpendicular to both [tex]\hat\alpha[/tex] and [tex]\hat\beta[/tex], then their dot products are zero.

Recall that for any vector [tex]\hat x[/tex], [tex]\hat x\cdot \hat x = \|\hat x\|^2[/tex].

Now, we have

[tex](\hat\gamma - c\hat\alpha - d\hat\beta) \cdot \hat\alpha = (\hat\gamma\cdot\hat\alpha) - c\|\hat\alpha\|^2 - d (\hat\beta\cdot\hat\alpha) = 0[/tex]

[tex]\hat\beta\cdot\hat\alpha = -1 + 2 - 6 = -5[/tex]

[tex]\implies 6c - 5d = -11[/tex]

and

[tex]\hat\gamma\cdot\hat\beta = -5 + 0 + 24 = 19[/tex]

[tex]\|\hat\beta\|^2 = (-1)^2 + 2^2 + 3^2 = 14[/tex]

The general equation of a straight line is given by -

y = mx + c

where -

m → slope of line.

c → y - intercept of line.

According to the question -

The y - intercept of the line is at the coordinates (0, 40). Now, we have to find the slope of this line. Consider the two coordinates -

A(0, 40) and B(10, 60)

Slope of a straight line is given by -

m = y₂ -y₁ / x₂ - x₁

m = 60 - 40 / 10 - 0

m = 20 / 10

m = 2

Now, substituting the values in the general equation of line, we get -

y = 2x + 40

Hence, Option B → y = 2x + 40 is the correct alternative.

The algebraic solution for the variable x is as follows:

The equation is represented as follows;

2 / 5 (2 - x) = - 1 / 3 x + 1 / 2

open the bracket on the left side

2 / 5 (2 - x) = - 1 / 3 x + 1 / 2

4 / 5  - 2x / 5 = - 1 / 3 x + 1 / 2

Add 1  /3 x to both sides

4 / 5  - 2x / 5 = - 1 / 3 x + 1 / 2

4 / 5  - 2x / 5 + 1 / 3 x  = - 1 / 3 x + 1 / 3 x  + 1 / 2

4 / 5 + 1 / 3 x - 2 / 5 x = 1 / 2

4 / 5 + 5x - 6x / 15 = 1 / 2

4  / 5  - x / 15 = 1 / 2

subtract 4 / 5 from both sides

4  / 5 - 4 / 5  - x / 15 = 1 / 2 - 4 / 5

- x / 15 = 5 - 8 / 10

- x / 15 = - 3 / 10

cross multiply

- x / 15 = - 3 / 10

-10x = - 45

divide both sides by -10

x = 45  /10

x = 9 / 2

The value of y is 9.

Perimeter is the total length of the boundary of any closed shape. It is basically the sum of all the sides of a given figure.

Perimeter of a rectangle is given by [ 2( l + b ) ] or (2 l + 2 b ) or

( l + l + b + b), here l and b represent the length and breadth of the given rectangle.

Perimeter of the given rectangle = 166 units               ( given )

Length of the given rectangle = 5y                                ( given )

Breadth of the given rectangle = (4y + 2)                     ( given )

By putting values in the formula, we get

perimeter = 2 ( l + b )

166 = 2 [ (5y) + (4y + 2) ]

166 = 2 [ 5y + 4y + 2 ]

166 = 2 [ 9y + 2 ]

166 = 2*9y + 2*2

166 = 18y + 4

166-4 = 18y  ( moving 4 to other side thus changing the sign to negative )

162 = 18y

162/18 = y  ( moving 18 to other side for further solution )

The value of y is 9.

The whole length of any closed shape's boundary is known as its perimeter. In essence, it is the total of a given figure's sides.

A rectangle's perimeter can be calculated using [2(l + b)] or (2 l + 2 b) or

(l + l + b + b), where l and b stand for the provided rectangle's length and width

The rectangle's perimeter is 166 units ( given )

The rectangle's length is 5y ( given )

Given rectangle's width equals (4y + 2) ( given )

When we enter values into the formula, we obtain

perimeter = 2 ( l + b )

166 = 2 [ (5y) + (4y + 2) ]

166 = 2 [ 5y + 4y + 2 ]

166 = 2 [ 9y + 2 ]

166 = 2*9y + 2*2

166 = 18y + 4

166-4 = 18y  ( moving 4 to other side thus changing the sign to negative )

162 = 18y

Because they both don't have big numbers so the are unequal

The angled relationship is the Same-side interior angle where x is 6 and ∠EFG is 102°

For the parallel lines ED and FG, where EF is the transversal,

The angle DEF and the angle EFG are same-side interior angles.

By the same-side interior angle theorem, we can say that the interior angles on the same side of the transversal are supplementary (the sum of the angles is 180°).

∠DEF = 13x°

∠EFG = 17x°

∠DEF + ∠EFG = 180°

13x + 17x = 180

30x = 180

x = 6

∠DEF = 13x = 13*6 = 78°

∠EFG = 17x = 17*6 = 102°

Therefore, the angles follow the same-side interior angles relationship, x = 6 and ∠EFG = 102°

Given that triangle FIM and triangle LAK are similar triangles, therefore, the ratio is true:

FM/LK = IM/AK

Length of FM = 8 units

Length of LK = 12 units

Length of IM = 6 units

Length of AK = ?

Substitute
