The length of a rectangle
is two times the width of the rectangle.
The perimeter of the rectangle is 24 cm.
Draw the rectangle on the centimetre grid.

The slope of the given line 2 / 3

Whenever the equation of a line is written in the form y = mx + b, it is called the slope-intercept form of the equation. The m is the slope of the line. And b is the b in the point that is the y-intercept (0, b). For example, for the equation y = 3x – 7, the slope is 3, and the y-intercept is (0, −7).

The given graph indicates that the two points are :

A( 3 , 0 ) and B (0 , -2 )

Thus the slope can be given by the formula mentioned below :

[tex]\frac{y_{2}- y_{1} }{x_{2}- x_{1} }[/tex]

this means - 2 - 0/ 0 - 3

= - 2/ -3

2 / 3

Thus the slope of the given line 2 /3

Answer:

There are 10 ghosts, 6 witches, and 4 scarecrows

Step-by-step explanation:

20 = ghosts, witches, and scarecrows.

ghost = x

20 = x + (x-4) + (x-4-2)

20 = 3x-10

30 = 3x

x = 10

10 = ghosts

10-4 = 6 = witches

10-4-2 = 4 = scarecrows

The number of witches and ghosts at the haunted house are 6 and 10 respectively.

Given that, a total of twenty ghosts, witches, and scarecrows at the haunted house.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the number of ghosts be x.

Here,

The number of witches is four less than the number of ghosts

Witches =x-4

The number of scarecrows is two less than the number of witches

Scarecrows =x-4-2

= x-6

Total=x+x-4+x-6

3x-10=20

⇒3x=30

⇒x=10

So, number of witches = 6 and number of scarecrows=4

Therefore, the number of witches and ghosts at the haunted house are 6 and 10 respectively.

The value of y which is calculated from the perimeter given = 7

Perimeter is defined as the sum total of all the sides of an object. Therefore the perimeter of a square is the sum of the four sides = a+ b+ c +d

The perimeter of the square= 132 units.

The given sides = 2(4y + 3) and ,2(5y)

That is,

132 = 2(4y + 3) + 2(5y)

A number with a whole number and a fractional component separated by a point is referred to as a decimal.

A number with a whole number and a fractional component separated by a point is referred to as a decimal.

The word Decimus, which means tenth in Latin, is derived from the base word Decem, or 10. As a result, the decimal system, often known as a base-10 system, has 10 as its fundamental unit.

The tenth place is represented by the first digit following the decimal. The hundredth place is represented by the digit that follows the decimal. Up until there are no more digits, the remaining ones keep the place values filled in.

The accepted method for representing both integer and non-integer numbers is the decimal numeral system. It is the expansion of the Hindu-Arabic numeral system to non-integer values. There are various ways to represent numbers in the decimal system referred to as decimal notation.

Given Information:

Average number of days = 28

Standard deviation = 7

Required Information:

Between what two values will approximately 95% of the number of days be?

Solution:

Recall the Empirical Rule,

68% of the data fall within 1 standard deviation from the mean.

95% of the data fall within 2 standard deviations from the mean.

99.7% of the data fall within 3 standard deviations from the mean.

Since we are asked for 95%

Lower limit = μ - (2)σ

Upper limit = μ + (2)σ

Where μ is the average number of days and σ is the standard deviation.

Lower limit = 28 - (2)7 = 28 - 14 = 14 days

Upper limit = 28 + (2)7 = 28 + 14 = 42 days

Part (b)

Estimate the percentage of customer accounts for which the number of days is between 21 and 35.

Lower limit = 21

Upper limit = 35

Lower limit = μ - (x)σ

21 = 28 - (x)7

(x)7 = 28 - 21

(x)7 = 7

x = 7/7 = 1

Which means that 68% of the customer accounts have payment made between 21 and 35 days.

What is percentage?

Suppose there is a number and the number has to be expressed as a fraction of 100. Then that number is called percentage.

For example, 2% means [tex]\frac{2}{100}[/tex]

Here,

Let the number be x

On increasing x by 10%, result = [tex]x + \frac{10}{100} \times x[/tex]

                                                  = [tex]x + \frac{x}{10}[/tex]

                                                  = [tex]\frac{10x +x}{10}[/tex]

                                                  = [tex]\frac{11x}{10}[/tex]

Now on increasing his answer by 10 %, result =

                                                                            [tex]\frac{11x}{10}+\frac{10}{100}\times \frac{11x}{10}\\\frac{11x}{10} + \frac{11x}{100}\\\frac{110x + 11x}{100}\\\frac{121x}{100}[/tex]

Total increase in number = [tex]\frac{121x}{100} - x[/tex]

                                           = [tex]\frac{121x-100x}{100} \\[/tex]

                                           = [tex]\frac{21x}{100}[/tex]

Percentage increase = [tex]\frac{\frac{21x}{100}}{x} \times 100[/tex]
