By CER methοd it can be cοncluded that ABCD is a parallelοgram.

CER stands fοr "Cοngruent, Equal, and Midpοint Rule". This methοd is based οn the prοperties οf parallelοgrams, where οppοsite sides are parallel and cοngruent, and οppοsite angles are equal. By using the CER methοd, we can prοve that a quadrilateral is a parallelοgram if it satisfies the cοnditiοns οf having οppοsite sides cοngruent, οppοsite angles equal, and diagοnals bisecting each οther at their midpοint.

Tο shοw that ABCD is a parallelοgram, we need tο demοnstrate that bοth pairs οf οppοsite sides are parallel.

Let's begin by finding the slοpe οf each side using the fοrmula:

slοpe = (change in y) / (change in x)

Slοpe οf AB = (3 - (-1)) / (1 - 2) = 4/-1 = -4

Slοpe οf BC = (5 - 3) / (6 - 1) = 2/5

Slοpe οf CD = (1 - 5) / (7 - 6) = -4

Slοpe οf DA = (-1 - 1) / (2 - 7) = -2/5

Nοw, we can use the fact that twο lines are parallel if and οnly if their slοpes are equal. Thus, we need tο check whether AB is parallel tο CD and whether BC is parallel tο DA.

AB is parallel tο CD if their slοpes are equal. Since the slοpe οf AB is -4 and the slοpe οf CD is alsο -4, we can cοnclude that AB is parallel tο CD.

BC is parallel tο DA if their slοpes are equal. Since the slοpe οf BC is 2/5 and the slοpe οf DA is alsο 2/5, we can cοnclude that BC is parallel tο DA.

Therefοre, since bοth pairs οf οppοsite sides are parallel, we can cοnclude that ABCD is a parallelοgram.

The area of each small triangle is equal to √(7)/8 times the square of the length of one side of the square.

First, we need to find the area of the larger triangle that is created by placing the two small triangles on top of the square. Let's call the base of the larger triangle "b" and the height of the larger triangle "h".

To find "b", we can use the length of one side of the square since the two small triangles are placed on top of the square. Let's call the length of one side of the square "s".

Since the two small triangles are congruent, we know that the base of each small triangle is equal to half of one side of the square, which is s/2. Therefore, the total base of the larger triangle is equal to the sum of the bases of the two small triangles, which is s/2 + s/2 = s.

To find "h", we need to use the Pythagorean theorem since the larger triangle is a right triangle. Let's call the hypotenuse of the larger triangle "c". Since the hypotenuse is the diagonal of the square, we know that its length is √(2)*s.

Using the Pythagorean theorem, we can find the height of the larger triangle:

h² + (s/2)² = c² h² + (s/2)² = (√(2)s)² h² + s²/4 = 2s² h² = 7s²/4 h = √(7)/2 x s

Now that we have found "b" and "h", we can use the formula for the area of a triangle:

Area = 1/2 x base x height

Area of the larger triangle = 1/2 x s x √(7)/2 x s = √(7)/4 x s²

Finally, we can find the area of each small triangle by dividing the area of the larger triangle by two:

Area of each small triangle = 1/2 x (√(7)/4 x s²) = √(7)/8 x s²

Answer:

6√3 cm.

Step-by-step explanation:

The angle between the length of a rectangle and its diagonal is 30°. If the length of the rectangle is 6cm, find the length of the diagonal.

Let's call the width of the rectangle "w" and the diagonal "d". We know that the angle between the length and diagonal is 30 degrees, which means that the angle between the width and diagonal is 90 - 30 = 60 degrees (since the angles in a triangle add up to 180 degrees).

Now, we can use trigonometry to find the length of the diagonal. Specifically, we can use the sine function, which relates the lengths of the sides of a right triangle to the angles opposite them:

sin(angle) = opposite/hypotenuse

In this case, the angle we're interested in is 60 degrees, the opposite side is the width "w", and the hypotenuse is the diagonal "d". So we can write:

sin(60) = w/d

Solving for "d", we get:

d = w/sin(60)

Now we just need to find the width of the rectangle. Since we know the length of the rectangle is 6cm, we can use the fact that the opposite sides of a rectangle are equal to each other to write:

w = length*sin(30) = 6sin(30)

We can simplify sin(30) to 1/2, so:

w = 6/2 = 3

Now we can substitute this value of "w" into our expression for "d" to get:

d = w/sin(60) = 3/sin(60)

We can simplify sin(60) to √3/2, so:

d = 3/(√3/2) = 6/√3 = 2√3 * 2

So the length of the diagonal is 2√3 times the length of the width, or approximately 3.46 times the length of the width. Therefore, the length of the diagonal is:

d = 2√3 * 3 = 6√3 cm.

By working out or simplifying the given statement we will get  a)  26 and the equation b)  8 2/3.

In mathematics, a fraction is used to denote a piece or component of the whole. It stands for the proportionate components of the whole. Numerator and denominator are the two components that make up a percentage. The numerator is the number at the top, and the remainder is the number at the bottom.

a) By converting the numbersr into improper fraction we will get

4 1/3 = (4 x 3 + 1) / 3 = 13 / 3

By multiplying the both of the fractions:

13 / 3 * 6 =[tex]\frac{78}{3}[/tex] = 26

= 4 1/3 * 6 simplifies to 26.

b) Now we will convert both of the mixed numbers to improper fractions and we will get :

[tex]\frac{23}{5}[/tex] = [tex]\frac{2*5+3}{5}[/tex] = [tex]\frac{13}{5}[/tex]

[tex]\frac{31}{3}[/tex] = [tex]\frac{3*3+1}{3\\}[/tex] = [tex]\frac{10}{3}[/tex]

By multiplying both of the  fractions:

[tex]\frac{13}{5} * \frac{10}{3\\}[/tex] = [tex]\frac{130}{5}[/tex]

We can simplify say that the fraction by dividing both of the numerator and denominator by their greatest common factor, which is 5:

[tex]\frac{130}{15}[/tex] =[tex]\frac{26}{3\\}[/tex]

(a + 1/a)³ = a³ + 3a + 3/a + 1/a³

We are given that a + 1/a = 4, so we can substitute that into the identity and simplify:

(a + 1/a)³ = (4)³ = 64

a³ + 3a + 3/a + 1/a³ = 64

a³ + 1/a³ + 3(a + 1/a) = 64

a³ + 1/a³ + 3(4) = 64

a³ + 1/a³ = 52

Therefore, we have proved that a³ + 1/a³ = 52 when a + 1/a = 4.

Answer: The radius of a circle is half of its diameter. Therefore, if the diameter of the circle is 3 cm, then the radius is 1.5 cm.

To set a pair of compasses to draw a circle with diameter 3 cm, open the compasses to a distance of 1.5 cm (which is the radius of the circle). The correct diagram in the link provided shows the compasses set to the correct radius.

So its A

The radius of the circle is 1.5cm.

A circle's diameter is divided in half by its radius. Thus, if the circle's diameter is 3 cm, the radius is:

radius = diameter/2 = 3cm/2 = 1.5cm

Any circular object's radius is the measurement from the centre to its outermost border or boundary. A radius is a dimension that applies to spheres, semispheres, cones with circular bases, and cylinders with circular bases in addition to circles.

It is possible to define a circle as the locus of a point travelling on a plane while maintaining a constant distance from a fixed point. The radius of a circle is the distance from any point on the circle to its centre. The fixed point is referred to as the centre of the circle.

The distance along a line drawn between two points on a circle and through the centre of the circle is the diameter of the circle. It is equivalent to double the circle's radius. It is typically indicated with a d or a D.

Diameter = 2 x Radius

Or

Radius = diameter / 2.

The circle's longest chord equals its diameter.

Moreover, we may relate a circle's area and circumference to its diameter.

Circle circumference equals (Diameter)

Circle area equals /4 (Diameter[tex])^2.[/tex]

From the given data, the test statistic is -2.052 and the p-value is 0.0461. The correct answer is option 5.

To perform a two independent samples t-test, we can use the following formula to calculate the test statistic:

t = (x₁ - x₂) / (s_p × √(1/n₁ + 1/n₂))

where x₁ and x₂ are the sample means, n₁ and n₂ are the sample sizes, s_p is the pooled standard deviation, calculated as:

s_p = √(((n₁ - 1) × s₁² + (n₂ - 1) × s₂²) / (n₁ + n₁ - 2))

Let's calculate the test statistic:

x₁ = 60.345, s₁ = 10.8968, n₁ = 25

x₂ = 67.635, s₂ = 12.936, n₂ = 20

s_p = √(((25 - 1) × 10.8968² + (20 - 1) × 12.936²) / (25 + 20 - 2)) = 11.8074

t = (60.345 - 67.635) / (11.8074 × √(1/25 + 1/20)) = -2.052

The degrees of freedom for the t-distribution can be calculated as:

df = n₁ + n₂ - 2 = 43

Using a two-tailed t-test at a significance level of 0.05, the critical t-value is ±2.016.

The p-value for the test is the probability of obtaining a t-value as extreme or more extreme than the calculated t-value, assuming the null hypothesis is true. Since the calculated t-value is outside the critical region (|t| > 2.016), the p-value is less than 0.05 and we can reject the null hypothesis in favor of the alternative hypothesis.

169-16=(b)²

The constraint 2X - Y = 0 states that the difference between variable X and twice variable Y must be equal to 0, meaning that X must be exactly twice the value of Y.The correct answer is C. 2X - Y = 0.

This constraint states that the difference between variable X and twice variable Y must be equal to 0. In other words, the value of variable X must be exactly twice the value of variable Y. This can be mathematically represented as 2X - Y = 0, meaning that 2 multiplied by X minus Y must equal 0. To illustrate this, let us assume that the value of variable X is 10 and the value of variable Y is 5. This means that 2X is equal to 20 and Y is equal to 5. When we subtract Y from 2X, we get 20 - 5 = 15. However, since the constraint states that the difference between X and twice Y must equal 0, the value 15 does not satisfy the condition. Therefore, the values of X and Y must be adjusted until the difference between X and twice Y equals 0. To satisfy the constraint, the value of X must be equal to 20 and the value of Y must be equal to 10. This means that X is exactly twice the value of Y, which satisfies the condition set by the constraint 2X - Y = 0.

What is meant by marginal frequency?

By dividing the sum or total of a row or the sum or total of a column by the total number of observations in a dataset, one can get the marginal relative frequency of a data set. This dataset is presented as a two-way table for ease of understanding. Although the percentage value is typically chosen, the marginal relative frequency can be stated as either a decimal or a percentage number.

Here,

The total number of middle school students = 21

Number of middle school students playing sports = 21 - 16 = 5

Number of high school students watching movies = 19-16 = 3

Total number of high school students = 11 + 3 = 14

Total number of students = 14 + 21 = 35

Now,

The marginal frequency of middle school students who chose to play sports = 5 / 35 = 0.143

The marginal frequency of high school students who decided to watch movies/TV = 3/35 = 0.0857

The marginal frequency of students in high school = 14/35 =0.4

The marginal frequency of students who chose to play sports = 15/35
