Complementary angles are two angles whose sum is equal to 90 degrees. In other words, if you add the measures of two complementary angles, you get 90 degrees. Complementary angles are often referred to as "complements" for short. For example, if one angle is 30 degrees, its complement would be 60 degrees.

Supplementary angles, on the other hand, are two angles whose sum is equal to 180 degrees. In other words, if you add the measures of two supplementary angles, you get 180 degrees. Supplementary angles are often referred to as "supplements" for short. For example, if one angle is 120 degrees, its supplement would be 60 degrees.

Answer:

concurrent lines

Step-by-step explanation:

If there are more than 2 lines (or in this case, 3 lines) that meet at a singular and same point, then they are called concurrent lines.

First, we need to calculate the total amount of time the machine runs each day:

Starting time: 09:30

Ending time: 16:10

We can convert the starting time and ending time to minutes:

09:30 = 9 x 60 + 30 = 570 minutes

16:10 = 16 x 60 + 10 = 970 minutes

The total running time of the machine is:

970 - 570 = 400 minutes

Since the machine produces a bolt every 8 seconds, we need to convert the running time from minutes to seconds:

400 x 60 = 24,000 seconds

Finally, we can calculate the number of bolts produced by dividing the total running time by the time it takes to produce one bolt:

24,000 / 8 = 3,000

Therefore, the machine produces 3,000 bolts each day.

The area of the parallelogram is[tex]39\sqrt(15)[/tex] square units.

In the preceding diagram, we must determine the height of the parallelogram in order to determine its area. The length of the perpendicular line segment drawn from vertex A to side BC determines the parallelogram's height. We'll refer to this line segment as AD. Since AD is perpendicular to BC, we can calculate its length using the Pythagorean theorem:

[tex]AD^2 = AC^2 - CD^2[/tex]

[tex]AD^2 = 12^2 - 3^2[/tex]

[tex]AD^2 = 135[/tex]

[tex]AD = \sqrt(135) = 3\sqrt(15)[/tex]

Now that we know the height of the parallelogram, we can use the formula for the area of a parallelogram:

Area = base x height

The base of the parallelogram is the length of side AB, which is 13 units. Therefore, the area of the parallelogram is:

[tex]Area = 13 \times 3\sqrt(15)[/tex]

[tex]Area = 39\sqrt(15) square units[/tex]

Therefore, the area of the parallelogram is [tex]39\sqrt(15)[/tex] square units.

The probability for the possibility on a failing the exam is  1/3 , shown on the scale.

A probability is a numerical representation of the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

Any collection of results constitutes an event. Events are represented by capital letters, such as A and B. For instance, if the experiment involves flipping a single fair coin, event A might only receive one head. P(A) represents the probability of an event A.

Given that-

probability = number of favourable outcome / total outcome

number of favourable outcome = 1

number of total outcome = 3

probability = 1/3

the overall gain is positive, we can conclude that the stockholder made a profit of $190.10. Therefore, the correct answer is: "The overall gain is $190.10."

How to solve the question?

To calculate the overall gain or loss, we need to first find the total cost of buying the shares and the total revenue from selling them.

For the 40 shares of Zycodec purchased at its lowest price of 29.39, the total cost would be:

40 shares x $29.39/share = $1,175.60

For the 95 shares of Unix purchased at its highest price of 16.12, the total cost would be:

95 shares x $16.12/share = $1,531.40

The total cost of purchasing both stocks would be:

$1,175.60 + $1,531.40 = $2,707

Now, we need to find the total revenue from selling the shares. The closing price of Zycodec is 34.95, so the revenue from selling 40 shares would be:

40 shares x $34.95/share = $1,398

The closing price of Unix is 15.78, so the revenue from selling 95 shares would be:

95 shares x $15.78/share = $1,499.10

The total revenue from selling both stocks would be:

$1,398 + $1,499.10 = $2,897.10

The overall gain or loss would be the difference between the total revenue and total cost:

Overall gain/loss = total revenue - total cost

Overall gain/loss = $2,897.10 - $2,707

Overall gain/loss = $190.10

Since the overall gain is positive, we can conclude that the stockholder made a profit of $190.10. Therefore, the correct answer is: "The overall gain is $190.10."

Answer:

Based on the information, the probability of rolling a number less than a 3 (that is, a 1 or a 2) is 56/200 = 7/25 = 28%.

The correct answer is (a) a = 0, b = two-thirds, c = 3.

This can be seen by comparing the given equation, y = two-thirds x squared + 3, to the general form of a quadratic equation, y = ax^2 + bx + c.

In the given equation, the coefficient of x^2 is two-thirds, so a = two-thirds. The coefficient of x is 0, so b = 0. And the constant term is 3, so c = 3.

The margin of error for the 95% confidence interval used to estimate the population proportion is 0.0680. So, the correct answer is option d.

Calculate the sample proportion:

The formula (p) = x/n, where x is the sample size (163) and n is the number of successes (96), yields the sample proportion.

Therefore, the sample proportion is 96/163 = 0.5896.

Calculate the standard error:

The formula SE(p) yields the sample proportion's standard error = √[p(1-p)/n], where n is the sample size, and p is the sample proportion.

Consequently, the sample proportion's standard error is as follows:

SE(p) = √[0.5896(1-0.5896)/163] = 0.037

Calculate the margin of error:

The margin of error is given by the formula ME = z × SE(p), where SE(p) is the standard error of the sample proportion and z is the z-score corresponding to the desired level of confidence.

The z-score for a 95% confidence interval is 1.96.

The average size of the 15 diameters is 25.00mm. Using the concept of percentages, the mass of copper, lead, and tin in the bronze bearing are 140 kg, 40 kg, and 20 kg, respectively.

To find the average size of the 15 diameters, we need to calculate the sum of all the dimensions and then divide by 15 (the total number of diameters).

The sum of the dimensions can be calculated as follows:

(5 x 24.99mm) + (6 x 25.01mm) + (4 x 25.00mm)

= 375.01mm

Now, we can calculate the average size by dividing the sum by 15:

Average size = 375.01mm / 15

= 25.00mm (rounded to 2 decimal places)

Therefore, the average size of the 15 diameters is 25.00mm.

The correct answer is D. Trapezoid EFGH is congruent to Trapezoid ABCD after undergoing transformation D.

Let's first define the transformations:

A. Translation down, followed by rotation of 90°, followed by dilation by a scale factor of 3.

B. Rotation of 45°, followed by a reflection, followed by a translation left.

C. Dilation by a scale factor of 12, followed by a translation up, followed by a reflection.

D. Reflection, followed by a dilation of a scale factor of 1, followed by a rotation of 180°.

To determine if Trapezoid EFGH is congruent to, an enlargement of, or a reduction of Trapezoid ABCD, we need to analyze the effects of each transformation on the trapezoid.

A. Translation down, followed by rotation of 90°, followed by dilation by a scale factor of 3.

This transformation involves moving the trapezoid down, rotating it 90 degrees clockwise, and then increasing its size by a scale factor of 3. This transformation does not preserve angles or side lengths, so Trapezoid EFGH is not congruent to Trapezoid ABCD.

B. Rotation of 45°, followed by a reflection, followed by a translation left.

This transformation involves rotating the trapezoid 45 degrees clockwise, reflecting it across a line of reflection, and then moving it left. This transformation does not preserve angles or side lengths, so Trapezoid EFGH is not congruent to Trapezoid ABCD.

C. Dilation by a scale factor of 12, followed by a translation up, followed by a reflection.

This transformation involves increasing the size of the trapezoid by a scale factor of 12, moving it up, and then reflecting it across a line of reflection. This transformation does not preserve angles or side lengths, so Trapezoid EFGH is not congruent to Trapezoid ABCD.

D. Reflection, followed by a dilation of a scale factor of 1, followed by a rotation of 180°.

This transformation involves reflecting the trapezoid across a line of reflection, then increasing its size by a scale factor of 1 (i.e., not changing its size), and then rotating it 180 degrees. This transformation preserves angles and side lengths, so Trapezoid EFGH is congruent to Trapezoid ABCD.
