The area of the rhombus is 54 sq. units

Area of the trapizium is 115 sq. units.

A quadrilateral called a rhombus has four equal-length sides. The term "equilateral quadrilateral" refers to a quadrilateral whose sides all have equal lengths.

A parallelogram's general characteristics are as follows:

In American and Canadian English, a quadrilateral having at least one set of parallel sides is referred to as a trapezoid. It is referred to as a trapezium in British and other varieties of English. In Euclidean geometry, a trapezoid is a convex quadrilateral by definition. The bases of the trapezoid are the parallel sides.

The area of a rhombus = ½ x (product of the lengths of the diagonals)

= ½ *18*6 = 54 sq. units

Area of the trapizium = ½ x (sum of the lengths of the parallel sides) x perpendicular distance between parallel sides

=½ *(17 + 29) * 5 = 115 sq. units.

The variance of 'x'  for the continuous distribution over the interval 40 to 44 is approximately b) 1.333

The variance of a continuous uniform distribution over the interval [a, b] is:

Calculate the variance using the formula:

                                       Var(x) = (b-a)^2/12

where [a, b] is the interval over which the continuous uniform distribution is defined

But putting a= 40 and b = 44, calculate the variance by putting them in the above formula

So, Var(x) = (44-40)^2/12

     Var(x) = 4^2/12

     Var(x) = 16/12

     Var(x) = 4/3

     Var(x) = 1.333

Therefore, the variance of 'x' for the continuous distribution over the interval 40 to 44 is approximately b) 1.333

Step-by-step explanation: To solve for e in this equation, you can start by isolating e on one side of the equation.

First, distribute the -2/5 on the left side of the equation:

-2/55 - 2/510e = e + 1/36e - 1/312

Now, you can combine like terms on both sides of the equation:

-2 - 4e = e + 2e - 4

Next, you can add e to both sides of the equation:

-2 - 3e = 2e - 4

Now you can add 3e to both sides of the equation:

-2 = 5e - 4

Now you can add 4 to both sides of the equation:

-6 = 5e

Finally, you can divide both sides of the equation by 5:

e = -6/5

So the value of e that satisfies the equation is -6/5.

The 15th term of the geometric progression is a₁₅ = 25/2048

A geometric progression is a sequence in which each term is derived by multiplying or dividing the preceding term by a fixed number called the common ratio.

The nth term of a GP is aₙ = arⁿ⁻¹

The general form of a GP is a, ar, ar2, ar3 and so on

Sum of first n terms of a GP is Sₙ = a(rⁿ-1) / ( r - 1 )

Given data ,

Let the 15th term of the geometric progression be a₁₅

Now , the 4th term of the GP is a₄ = -25

The 9th term of the GP is a₉ = 25/32

Now , nth term of a GP is aₙ = arⁿ⁻¹

Substituting the values in the equation , we get

a₄ = ar³ = -25   be equation (1)

a₉ = ar⁸ = 25/32   be equation (2)

Divide equation (2) by equation (1) , we get

r⁵ = -( 1/32 )

r⁵ = - ( 1/2 )⁵

So , the common ratio r = -1/2

Now , the first term of the GP a is calculated by

ar³ = -25

when r = -1/2

a ( -1/2 )³ = -25

a/8 = 25

a = 200

Now , the 15th term of the geometric progression a₁₅ = ar¹⁴

Substituting the values in the equation , we get

a₁₅ = 200 ( -1/2 )¹⁴

a₁₅ = 200/16,384

a₁₅ = 25/2048

Based on the numerical data, we can estimate that 26 more labor hours will be necessary to satisfy the labor hours required without overtime.

The Fair Labor Standards Act, enacted by the federal government, places a cap on the number of hours per week (40 hours) that businesses may demand their employees to perform in exchange for regular pay. Employers were now required to give employees who put in more than 40 hours of work additional compensation in the form of overtime pay.

Hence,

Overtime pay is usually 1.5 times the employee's regular hourly wage.

So, if an employee is paid $15 per hour, their overtime rate is $22.50 per hour ($15 multiplied by 1.5).

If another employee is paid $25 per hour, overtime is $37.50 per hour ($25 x 1.5).

To determine how old each person now, use algebraic expression and equation.

Let x = current age of Lisa

y = current age of Myra

If the sum of Lisa's age and Myra's age is 40, then we can express it as:

x + y = 40

x = 40 - y

If in 10 years, Lisa will be 3 times as old as Myra, then we can express it as:

x + 10 = 3(y + 10)

x + 10 = 3y + 30

x - 3y = 20

Substitute the equation for x into the 2nd equation and solve for y.

x - 3y = 20

(40 - y) - 3y = 20

40 - 4y = 20

4y = 20

y = 5

Substitute the value of y into the equation for x and solve.
