5)
a) All the angles in the diagram are equal to ∠45°
b) Line BC = 6√2
c) Line BE  = 6

The above are solved using the principles behind the properties of Parallelograms; Rhombus, Rectangle, and Square.

Since the above answers are justified by the qualities or properties of :

Parallelograms; Rhombus, and Rectangle, let's look at them one by one.

2

a)

A = 8 - opposite sides of a parallelogram are equal in length

b = 10 -opposite sides of a parallelogram are equal in length

y = 62° - opposite angles of a parallelogram are of equal measure.

x = 118° - Sum of angles of a parallelogram - 360°. x = (360 - (62*2))/2

= 118°

3)

(a) Here we have a Rhombus.

∠2 = 25° - Opposite angles of a rhombus are equal; Diagonals bisect the angles of a rhombus. Thus ∠1≅∠2

∠3 = 65° - Since diagonals bisect each other at right angles, ∠3 = 180 - (25+90) = 65°

∠4 = 65° - Diagonals bisect the angles of a rhombus. Thus, ∠3≅∠3

∠5 = 90° - [properties of a Rhombus]

(b)

since SL = 10,

i) LT  10 - All sides of a Rhombus are equal

ii) TM = 10 - All sides of a Rhombus are equal

iii) SM = 10 - All sides of a Rhombus are equal

4) Here we have a Rectangle.

a) Since m∠18

∠2 = 18° because The diagonals bisect each other; and both the diagonals have the same length. Thus, m∠2≅∠1 (AAS)

∠3 = 72° - Each interior angle is equal to 90 degrees. Thus, m∠ =  90-18 = ∠72°

∠4 = 72° - because The diagonals bisect each other; and both the diagonals have the same length. Thus, m∠4≅∠3(AAS)

If FA = 27, then LO = 13.5 - The diagonals bisect each other.Thus,

LO = FA/2

LO = 27/2

LO = 13.5

5) Here we have a square.
a) All the angles in the diagram are equal to ∠45°. This is because, the diagonals bisect all interior angles. Since each interior angle is 90°, thus, each of the resulting angle bisected 45°

b) Line BC = 6√2 - This is be
c) Line BE  = 6

The length of one-half of the diagonal of a square can be found using the Pythagorean theorem, which relates the lengths of the sides of a right triangle.

Let s be the side length of the square. Then, the length of the diagonal of the square (d) can be found using the equation d = s√2.

In this case, s = 6√2. So, the length of the diagonal (d) is:

d = s√2 = (6√2)√2 = 6(√2)(√2) = 6(2) = 12

Therefore, one-half of the diagonal of the square is:

(1/2)d = (1/2)(12) = 6

So, the length of one-half of the diagonal of the square ABCD is 6.

The number line for a < 3 is as shown in the figure below and we use an open circle on 3 and all the numbers to the left of 3 in the number line will be the values of a.

What is a number line?

A number line is a representation of a graduated straight line that is used to represent real numbers visually. It is assumed that every point on a number line corresponds to a real number and that every real number corresponds to a point. The endpoints of this line go on forever.

We can see the values that inequality represents by placing them on a number line. On a number line, inequalities are represented by drawing a straight line and designating the endpoints with either an open or closed circle. An empty circle indicates that the value is not included. A closed circle indicates that the value is included.

Given the inequality a < 3.

This means that the value of a is less than three and does not include three.

Therefore we use an open circle on 3 and all the numbers to the left of 3 in the number line will be the values of a.

Answer:

y = -5 [tex]\frac{1}{5}[/tex] o r -5.02 as a decimal

Step-by-step explanation:

-5(y + 0.2) = 25  Distribute the -5

-5(y) + -5(0.2) = 25   Adding a negative is the same as subtracting a positive

-5y - 1 = 25   add 1 to both sides

-5y - 1 + 1 = 25 + 1

-5y = 26  Divide both sides by -5

[tex]\frac{-5y}{-5}[/tex] = [tex]\frac{26}{-5}[/tex]

y = -5 [tex]\frac{1}{5}[/tex] o r -5.02 as a decimal

Answer: To solve the equation -5(y + 0.2) = 25, we need to isolate y by performing the following steps:

Distribute the -5 to the expression inside the parenthesis:

-5 * y - 5 * 0.2 = 25

-5y - 1 = 25

Add 1 to both sides of the equation to isolate -5y on one side:

-5y - 1 + 1 = 25 + 1

-5y = 26

Divide both sides of the equation by -5 to find y:

(-5y) / -5 = 26 / -5

y = -5.2

So, the solution to the equation -5(y + 0.2) = 25 is y = -5.2.

The degrees of freedom for error in a two-way ANOVA experiment with 3 levels for factor a, 7 levels for factor b, and 100 replications is 2071.

The degrees of freedom (df) for error in a two-way ANOVA experiment depend on the sample size (n) and the number of parameters estimated in the model.

In a two-way ANOVA experiment, we are interested in modeling the response variable as a function of two factors, a and b, and their interaction. The model can be written as follows:

Yij = μ + αi + βj + (αβ)ij + εij

In general, the df for error can be calculated as follows:

df error = n - k

where k is the number of parameters estimated in the model.

In our case, we have 3 levels for factor a, 7 levels for factor b, and 100 replications. Therefore, the total sample size is n = 3 x 7 x 100 = 2100.

To estimate the parameters in the model, we need to calculate the following:

The overall mean μ

The effect of factor a, αi, for i = 1, 2, 3

The effect of factor b, βj, for j = 1, 2, ..., 7

The interaction effect between factors a and b, (αβ)ij, for i = 1, 2, 3 and j = 1, 2, ..., 7

Therefore, the total number of parameters estimated in the model is

=> k = 1 + 3 + 7 + 3 x 7 = 29.

Finally, we can calculate the df for error as:

df error = n - k = 2100 - 29 = 2071.

For the given equation which shows the relation of temperature in Celsius and Fahrenheit, the correct option is Option D.

What is meant by temperature?

Indicating the direction in which heat energy will naturally flow from a hotter body (one with a higher temperature) to a colder body(one at a lower temperature), the temperature is a measure of hotness or coldness defined in terms of any of several arbitrary scales.

The given equation is:

[tex]C = \frac{5}{9} (F- 32)[/tex]

where C = temperature in Celsius

          F = temperature in Fahrenheit

The above equation can be rewritten as:

C = 5/9F - 160/9

Now, this is an equation of a straight line with a formula,

y = mx + c

Comparing,

m = 5/9 which is the slope of the equation.

This means that for a temperature increase of 1 degree Fahrenheit, the equivalent increase in temperature in Celsius is 5/9.

So the option I is true.

Similarly, an increase in 1 degree Celsius of temperature is equivalent to 9/5 = 1.8 degree increase in Fahrenheit.

So option II is true.

Option III is not true as is discussed above.

Therefore for the given equation of temperature, the correct option is Option D.

In rectangle WXYZ, the length of each diagonal are 40.97 units and 39.98 units.

To find the lengths of the diagonals of rectangle WXYZ, we can use the Pythagorean theorem.

The diagonal WX is the hypotenuse of right triangle WXY, so we have:

WX^2 = WY^2 + XY^2

Similarly, the diagonal YZ is the hypotenuse of right triangle XYZ, so we have:

YZ^2 = XY^2 + XZ^2

Substituting the given values for WY and XZ, and x = 2, we get:

WY = 24(2) - 8 = 40

XZ = -18(2) + 13 = -23

Plugging these values into the equations above and simplifying, we get:

WX^2 = 40^2 + XY^2

YZ^2 = XY^2 + (-23)^2

Since XY is a common side of both triangles, we can solve for it by setting the two expressions for XY^2 equal to each other:

40^2 + XY^2 = XY^2 + (-23)^2

Simplifying, we get:

40^2 + 23^2 = 2XY^2

XY^2 = (40^2 + 23^2) / 2 = 1039

Substituting this value for XY^2 in the equations for WX^2 and YZ^2, we get:

WX^2 = 40^2 + 1039 = 1679

YZ^2 = 1039 + (-23)^2 = 1598

Taking the square roots, we get:

WX = sqrt(1679) ≈ 40.97

YZ = sqrt(1598) ≈ 39.98

Therefore, the length of each diagonal of Rectangle are approximately 40.97 units and 39.98 units.
