Explain WHY a rotation of 180° is the same as doing
reflection over the x-axis AND the y-axis?

Answer:

(-1, 3)

Step-by-step explanation:

No, the statements a) If she attends the meeting, she will become the secretary b) If she does not become the secretary, then she did not attend the meeting are not equivalent.

The statement "a" says that if she attends the meeting, then she will become the secretary. This is a sufficient condition for her to become the secretary.

The statement "b" says that if she does not become the secretary, then she did not attend the meeting. This is a necessary condition for her not attending the meeting.

So, while the statements are related, they don't represent the same relationship between the events of attending the meeting and becoming the secretary.

The solution to the equation is y = 1/6

Given data:

To find the value of y in the solution of the system of equations:

10x + 24y = 9 ...(1)

8x + 60y = 14 ...(2)

We can use the method of substitution or elimination to solve the system. Let's use the method of substitution:

From equation (1), isolate x:

10x = 9 - 24y

x = (9 - 24y)/10

Now substitute this value of x into equation (2):

8((9 - 24y)/10) + 60y = 14

Simplify and solve for y:

(72 - 192y)/10 + 60y = 14

72 - 192y + 600y = 140

408y = 68

y = 68/408

y = 1/6

Hence, the value of y in the solution of the system of equations is y = 1/6.

Answer: Try this:

Step-by-step explanation:

798 rounded to one sig. fig. = 800.

8 is already just one sig. fig.

41 rounded to one sig fig. Is 40.

800/8x40

800/320 = 2.5.......

Rounded to one sig fig. =3

Or if you left the entire equation as is and just rounded the answer to 1 sig. fig.

798/(8x41) = 2.4329.......

rounded to one sig fig =2

Without knowing what specifically the question wants estimated to one significant figure, there could be multiple answers.

The estimate of the equation to one significant figure is 2.

Significant figures are the digits in a number that is significant and required to denote a value and also add to the correctness of that value.

The way we will solve this equation is to first determine the final value and then approximate it to 1 significant figure.

\(\mathbf{= \dfrac{798}{8 \times 41}}\)

= 2.4329

The value of x will be 33 units approximately. Thus, option A is correct.

Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.

We need to find the value of x

so first

Tan 60 = Perpendicular / 11√6

Perpendicular = 1.732 (11√6)

Perpendicular = 46.66

Then,

Sin 45 = Perpendicular / x

Sin 45 = 46.66/ x

x = 33.00

So, the value of x will be 33 units approximately.

Thus, option A is correct.

The complementary event to drawing a blue marble would be "not drawing a blue marble." A complementary event is an event that is mutually exclusive with the original event, which means that only one of the events can occur at a time.

What is a complementary event?

The complementary event is defined as the event that comprises of all outcomes that are not part of the event A. If event A is the occurrence of a specific event, the complementary event would be any outcome other than that. The sum of the probabilities of an event and its complementary event will always equal one.

What are mutually exclusive events?

Two events that cannot occur at the same time are called mutually exclusive events. That is to say, if event A happens, event B cannot happen and vice versa. The likelihood of mutually exclusive events occurring simultaneously is 0. If two events are not mutually exclusive, they can occur at the same time.Therefore, not drawing a blue marble is a complementary event to drawing a blue marble.

The raster data model is commonly used to represent field features, but it is not suitable for representing point, line, and polygon features.

The raster data model is a grid-based representation where each cell or pixel contains a value representing a specific attribute or characteristic. It is well-suited for representing continuous spatial phenomena such as elevation, temperature, or vegetation density. Raster data is organized into a regular grid structure, with each cell having a consistent size and shape.

However, the raster data model has limitations when it comes to representing discrete features like points, lines, and polygons. Since raster data is based on a grid, it cannot precisely represent the exact shape and location of these features. Instead, they are approximated by the cells that cover their extent.

Answer:

54 degrees.

Step-by-step explanation:

So a fun fact is that the exterior angle is equal to the sum of the opposite two interior angles (at least within triangles).

Given this, set these values equal to each other to get the value of a.

d = a + b

2a = (a+10)+44

2a = a + 54

a = 54

The measure of the exterior angle is 54 degrees.

The height of the triangle whose base is 4 cm and area is 20 cm² is 10 cm .

It is given that base is 4 cm and area is 20 cm² .

Putting above values in area formula , we get

         Area = 1 / 2 × base × height

            20  = 1 / 2 × 4 × height

             20 = 2 × height

The board is 3 1/6 feet left. The correct option is C.

To find out how much of the board is left, we need to subtract the length of the section that was cut off from the original length of the board:

6 2/3 - 3 1/2

To subtract these two mixed numbers, we need to find a common denominator. The smallest common denominator of 3 and 2 is 6:

Next, we can simplify the fractions,

62/3 - 3 1/2

= 20/3 - 7/2

= (40 - 21)/6

= 19/6

= 3 1/6 feet.

Step-by-step explanation:

After considering the given data we conclude that a) the mean of the given trials is about 1.0526 trials before failing, b) the probability of first failure occurring in the tenth trial is  0.2%.

a. To evaluate the mean number of trials until failure, we can apply the geometric distribution, since the probability of success (i.e., correct recognition) is 0.95 and the trials are assumed to be independent.

The geometric distribution has a mean of 1/p,

Here

p = probability of success.

Then, the mean number of trials until failure is 1 / p

= 1/0.95

= 1.0526

So, the mean that the device will correctly recognize faces for about 1.0526 trials before failing.

b. To evaluate the probability that the first failure occurs on the tenth trial, we can apply the geometric distribution again.

The probability of the first failure talking place on the tenth trial is the probability of having nine successes followed by one failure.

Can be written as

P(X = 10) = (0.95)⁹ × (0.05)

= 0.02

Hence, the probability that the first failure occurs on the tenth trial is 0.002, or 0.2%.
