The specified details of the triangle, obtained using the segments joining the midpoints of the sides of the triangle ΔADG and trapezoid ACFG indicates that we get;

4. [tex]\overline{CE}[/tex] is a midsegment of ΔBDF

[tex]\overline{BF}[/tex] is the midsegment of trapezoid ACFG

5. CE = 12 cm, AG = 36 cm

6. m∠2 = 116°, m∠3 = 32°, m∠4 = 58°, m∠5 = 58°, m∠6 = 64°

The midpoint of a segment or the side of a triangle is a point that divides the segment into two parts of the same length.

4. The details of the diagram indicates that the segment [tex]\overline{CE}[/tex] is the midsegment of triangle ΔBDF

[tex]\overline{BF}[/tex] is the midsegment of trapezoid ACFG

5. [tex]\overline{CD}[/tex] is congruent to [tex]\overline{BC}[/tex] by the definition of the midpoint of [tex]\overline{BD}[/tex], similarly;

[tex]\overline{BC}[/tex] is congruent to [tex]\overline{AB}[/tex], by the definition of midpoint of [tex]\overline{AC}[/tex], therefore;

[tex]\overline{CE}[/tex] is the midsegment of triangle ΔBDF, therefore;

CE = (1/2) × BF

CE = (1/2) × 24 cm = 12 cm

CE = 12 cm

ΔBDF and ΔADG and ΔCDE are similar triangles, therefore;

[tex]\overline{BD}[/tex] = (2/3) × [tex]\overline{AD}[/tex]

Similarly, by the relationship between similar triangles we get;

[tex]\overline{BF}[/tex] = (2/3) × [tex]\overline{AG}[/tex]

BF = 24 cm, therefore;

24 = (2/3) × AG

AG = (3/2) × 24 = 36

AG = 36 cm

6. The length of a median of a right triangle, drawn from the right angled vertex, is half the length of the hypotenuse side.

Therefore; ΔACM and ΔABM are an isosceles triangles

m∠1 = m∠3 = 32°

m∠2 = 180° - (32° + 32°) = 116°

m∠2 = 116°

m∠3 = 32°

m∠4 = m∠5 = 90° - m∠1

m∠4 = m∠5 = 90° - 32° = 58°

m∠4 = 58°

m∠5 = 58°

m∠6 = 180° - (m∠4 + m∠5)

m∠6 = 180° - (58° + 58°) = 64°

m∠6 = 64°

Step-by-step explanation:

The line of best fit suggests that the temperature of the water in the beaker after 6 minutes will be approximately 91.8°C. This is because when x = 6, the equation gives us y = 91.8.

The line of best fit for this data is y = 5.3x + 23. This equation can be used to make a conjecture about the temperature of the water in the beaker if heated for 6 minutes. To calculate this, substitute x = 6 into the equation: y = 5.3(6) + 23. Simplifying this equation, we get y = 31.8 + 23, which gives us y = 54.8. This is the temperature of the water in the beaker if heated for 6 minutes, which is approximately 91.8°C. hence, The line of best fit suggests that the temperature of the water in the beaker after 6 minutes will be approximately 91.8°C. This is because when x = 6, the equation gives us y = 91.8.

a. Midpoint of AB, BC, CD, DA is (4,4), (0,-4), (-4,-4),(-4,4) respectively. b.  polygon formed by connecting the consecutive midpoints. c.  get a smaller square inside the square.

In geometry, the midpoint refers to the point that is exactly halfway between two given points, lines, or line segments. It is the point that divides a line segment into two equal parts. The midpoint is also known as the half-way point.

The midpoint can be found using a variety of methods, but the most common one is by using the midpoint formula, which is:

Midpoint = [(x1 + x2)/2, (y1 + y2)/2]

Where (x1, y1) and (x2, y2) are the coordinates of the two points.

The midpoint is an important concept in many mathematical and scientific fields, including physics, engineering, and computer graphics. It is often used to determine the center of mass, the point of balance, or the halfway point in a process or journey.

a. We can use the midpoint formula to find the midpoint of each side of the square:

Midpoint of AB: ((0+8)/2, (8+0)/2) = (4,4)

Midpoint of BC: ((0+0)/2, (-8+0)/2) = (0,-4)

Midpoint of CD: ((-8+0)/2, (0-8)/2) = (-4,-4)

Midpoint of DA: ((-8+0)/2, (0+8)/2) = (-4,4)

b. Connecting the consecutive midpoints of each side of a square creates a smaller square inside the original square. We can see this by observing that the midpoints of opposite sides of a square form the vertices of a smaller square.

The polygon formed by connecting the consecutive midpoints of each side of the square is a square.

c. If we repeat the process of connecting consecutive midpoints one more time, we will get a smaller square inside the square formed in part (b). This smaller square will have vertices at the midpoints of the sides of the square formed in part (b). We can see this by observing that the midpoints of the sides of a square form the vertices of a smaller square inside that square.

So the polygon that would result from connecting the consecutive midpoints of each side of the polygon determined in part (b) is another square.

The point estimate of the population​ proportion, the margin of error is 0.365.

Margin of error is a statistic that expresses the amount of random sampling error in survey results. The larger the margin of error, the less confident people are that the poll results will reflect the overall census results. When the population is incompletely sampled and the resulting measure has a positive variance, the margin of error will be positive, i.e. the measures differ. The term margin of error is often used in non-survey contexts to refer to the error observed in the reporting of measured quantities.

Applying the laws of cosine, in the second section of her ride, Andariel traveled about 3.012 km, as rounded to 2 decimal places.

The law of cosines is a mathematical formula used to determine the unknown length or angle of a triangle when two sides and an angle or all three sides are known.

Hence, we can think of it as trying to know Andariel's travel distance around a big triangle.

Thus to calculate, using the law of cosines, we have:

[tex]c^2 = a^2 + b^2 - 2ab*cos(C)[/tex]

Where in our case:

If we substitute the values above into the cosine formula, we get:

[tex](5.5)^2 = (6)^2 + (x)^2 - 2(6)(x)*cos(55)[/tex]

[tex]30.25 = 36 + x^2 - 12.0627x[/tex]

Simplifying and rearranging the equation further:

[tex]x^2 - 12.0627x + 5.75 = 0[/tex]

Applying the quadratic formula to simply:

[tex]x = (12.0627 ± sqrt(12.0627^2 - 415.75))/2[/tex]

x = 9.05 or x =3.012.


Remember, we are told Andariel turned left twice and ended up at her starting position, we know that she traveled in a closed loop.

Therefore, the distance she traveled in the second section of her ride must be less than 6 km (the distance she traveled east in the first section). Thus, the distance she traveled last or second section of her ride was 3.012 km.

The trig ratios as fractions expressed in simplest terms is :cos(K) = 8 √(17)/17  , sin(L) = 9 √(17)/17

Trigonometric ratios are mathematical relationships between the angles and sides of a right-angled triangle. They are ratios of the lengths of two sides of a right triangle in relation to one of its acute angles. The three primary trigonometric ratios are sine, cosine, and tangent, which are commonly denoted as sin, cos, and tan, respectively.

Sine: The sine of a right triangle angle seems to be the ratio of the length of the opposite side towards the length of the hypotenuse.

Cosine: The cosine of an angle in a right triangle is the ratio of the length of the adjacent side to the angle towards the length of the hypotenuse.

Tangent: In a right triangle, the tangent of an angle is really the ratio of the length of the side opposite the angle to the length of the adjacent side.

Given: A right angle triangle JKL, with angle J = 90 degrees, JL = sqrt(17), JK = 8, LK = 9

We can use the following trigonometric ratios:

To find the values of sin(L) and cos(K), we need to identify the opposite, adjacent and hypotenuse sides of the angles L and K.

For angle K:

cos(K) = adjacent/hypotenuse = JK/JL = 8/√(17)

To make the fraction easier to understand, multiply the numerator and denominator by √(17):

cos(K) = (8/√(17)) x (√(17)/√(17)) = (8 √(17))/17

Therefore, cos(K) = 8 √(17)/17

For angle L:

sin(L) = opposite/hypotenuse = LK/JL = 9/√(17)

To make the fraction easier to understand, multiply the numerator and denominator by √(17):

sin(L) = (9/√(17)) x (√(17)/√(17)) = (9 √(17))/17

Therefore, sin(L) = 9 √(17)/17

The compound interest on birr 5006 at 5% for 4 years compounded annually​ is $1,078.82.

Compound interest is a type of interest that is calculated not only on the initial principal amount but also on the accumulated interest of previous periods.

In other words, the interest earned during each period is added to the principal amount, and the interest for the next period is calculated on the sum of the principal and the accumulated interest.

Given that:

First, convert R as a percent to r as a decimal

r = R/100

r = 5/100

r = 0.05 rate per year,

Then solve the equation for A

A = P(1 + r/n)^(nt)

A = 5,006(1 + 0.05/1)^(1*4)

A = 5,006(1 + 0.05)^(4)

A = $6,084.82

Compound interest =Amount - Principal

Compound interest = 6084.82 - 5006

Compound interest = $1,078.82

Therefore, The total amount accrued, principal plus interest, with compound interest on a principal of $5,006.00 at a rate of 5% per year compounded 1 time per year over 4 years is $6,084.82.

There is a 1/3 chance, or around 0.333, that a randomly chosen passenger will have to wait longer than 10 minutes during one of these times.

What is probability?

Calculating the likelihood of experiments happening is one of the branches of mathematics known as probability. We can determine everything from the likelihood of receiving heads or tails when tossing a coin to the likelihood of making a research blunder, for instance, using a probability.

Since waiting times follow a uniform distribution on the interval from 0 to 15 minutes, the probability density function (PDF) is:

f(x) = 1/15, for 0 ≤ x ≤ 15

The probability that a randomly selected passenger has to wait more than 10 minutes is:

P(X > 10) = ∫10¹⁵ f(x) dx

P(X > 10) = ∫10¹⁵ 1/15 dx (since f(x) = 1/15 for 0 ≤ x ≤ 15)

P(X > 10) = [x/15]10¹⁵

P(X > 10) = (15 - 10)/15

P(X > 10) = 5/15

P(X > 10) = 1/3

Therefore, there is a 1/3 chance, or around 0.333, that a randomly chosen passenger will have to wait longer than 10 minutes during one of these times.

It seems that the table has not been provided in the question. However, I can provide a general method to complete the table based on the given information.

If each rectangle is 16% longer than the original, we can calculate the length of each new rectangle by adding 16% of the original length to the original length.

Let L be the original length of the rectangle. Then, the length of the new rectangle would be L + 0.16L = 1.16L.

Using this formula, we can calculate the length of the new rectangle for any given original length. For example, if the original length is 10 cm, then the length of the new rectangle would be:

1.16 x 10 cm = 11.6 cm
