What is the area of this trapezoid?

Answer: 40%

Step-by-step explanation: There is a pretty simple way of knowing this and basically you just remove a zero from the 400 and 1000 and you get 40 out of 100, meaning 40%, this does not work with calculating all percentages, only certain problems like this.

The probability that a randomly selected group of shoppers will spend a total of more than is 7.86%.

Standard deviation = √n × σ

                                = √50 × 30

                                = 212.1320

P( Σx > 5300) = P( Σx - nu / √n * σ > 5300 - 5000/212.1320)

                      = P(z > 1.414)

                      = 1 - P( z< 1.414)

                      = 0.078621

                      = 7.86%

The list that gives the sample space for pulling 2 marbles from the bag with replacement is given as follows:

List 4.

A sample space is a set that contains all possible outcomes in the context of an experiment.

The fact that the experiment is with replacement means that for each of the two marbles, there are two possible outcomes.

Then, applying the Fundamental Counting Theorem, the total number of outcomes is given as follows:

4 x 4 = 16.

This means that the correct list is either the list 3 or the list 4.

As there is replacement, it is possible to take two purple marbles, even though there is only one purple marble, as the same can be taken with replacement, and thus the correct list is given by list 4.

According to source-filter theory, phones (speech sounds) that have two sources are known as voiced sounds. Voiced sounds are produced by the vibration of the vocal folds in the larynx, creating a periodic source of sound. In contrast, unvoiced sounds are produced without vocal fold vibration and have only one source, which is typically the turbulent airflow through the vocal tract.

Source-filter theory is a model used to explain the production of speech sounds. It states that speech production involves two main components: a source of sound and a filter that shapes the sound produced by the source. The source represents the vibrating elements in the vocal tract, and the filter refers to the resonances and articulatory movements of the vocal tract.

Voiced sounds, such as vowels and certain consonants like /b/, /d/, and /g/, have two sources. The first source is the vocal folds, which vibrate and produce a fundamental frequency called the pitch. The second source is the filtering effect of the vocal tract, which modifies the sound produced by the vocal folds, resulting in different phonetic qualities.

In contrast, unvoiced sounds, such as /p/, /t/, and /s/, have only one source, which is the turbulent airflow through the vocal tract. These sounds do not involve vocal fold vibration and are produced solely by the filtering effect of the vocal tract.

Therefore, according to source-filter theory, voiced sounds are the type of phones that have two sources, while unvoiced sounds have only one source.

Answer:

(i) The value of m when t = 30 is 13.2

(ii) The value of t when the mass is half of its value at t=0 is 34.7

(iii) The rate of the mass when t=50 is -0.18            

Step-by-step explanation:

(i) The m value when t = 30 is:

\( m = 24e^{-0.02t} = 24e^{-0.02*30} = 13.2 \)

Then, the value of m when t = 30 is 13.2

(ii) The value of the mass when t=0 is:

\( m_{0} = 24e^{-0.02t} = 24e^{-0.02*0} = 24 \)    

Now, the value of t is:

\( ln(\frac{m_{0}/2}{24}) = -0.02t \)

\( t = -\frac{ln(\frac{24}{2*24})}{0.02} = 34.7 \)

Hence, the value of t when the mass is half of its value at t=0 is 34.7

(iii) Finally, the rate at which the mass is decreasing when t=50 is:

\( \frac{dm}{dt} = \frac{d}{dt}(24e^{-0.02t}) = 24(e^{-0.02t})*(-0.02) = -0.48*                            (e^{-0.02*50}) = -0.18 \)

Therefore, the rate of the mass when t=50 is -0.18.

Answer:

\(\displaystyle s(t)=\frac{3}{4}t^3+10t^3+5t+3\)

Step-by-step explanation:

Integrate v(t) with respect to time

\(\displaystyle \int(3t^3+30t^2+5)\,dt\\\\=\frac{3}{4}t^4+10t^3+5t+C\)

Plug-in initial condition to get C

\(\displaystyle s(0)=\frac{3}{4}(0)^3+10(0)^3+5(0)+C\\\\3=C\)

Thus, the position function is \(\displaystyle s(t)=\frac{3}{4}t^3+10t^3+5t+3\) given the velocity function and initial condition.

When two rays intersect an angle is created, As different classification of angles are there on the basis of measurement of angles and on the basis of properties of angles.

When two rays or straight lines intersect at one of their ends, an angle is created. Vertex of an angle refers to the point at which two points meet. The Latin word "angulus," which means "corner," is the origin of the English term "angle."

Symbol of Angle

The symbol ∠ represents an angle. Angles are measured in the form of degrees (°) using a protractor.

For example, 45 degrees is represented as 45°

Sections of Angles

Types of Angles

Based on their measurements, here are the many types of angles:

Interior and Exterior Angles:

Interior angles: Interior Angles are angle formed inside the shape.

Exterior angles: Exterior angles are to be angles that is formed outside a shape, between any side of  shape and to an extended adjacent side.

Complementary and Supplementary Angles:

Complementary angles: Angles that add up to 90° (a right angle) are called complementary angles.

Supplementary angles: Angles that add up to 180° (a straight angle) are called supplementary angles.

Answer:

  $735

Step-by-step explanation:

We assume the cover needs to cover the pool only, not any extra area around the pool.

The cost is given per square foot, so to find the total cost, we need to know how many square feet the cover must cover. The cost will be found by multiplying the cost per square foot by the number of square feet.*

The dimensions of the pool are given as 35 ft by 70 ft. The pool area is the product of these dimensions.

  A = LW

  A = (70 ft)(35 ft) = 2450 ft²

Then the cost is ...

  C = ($0.30/ft²)(2450 ft²) = $735

The cost to buy a pool cover is $735.

__

* This is the same rule you use for any purchase. The total cost is the cost per item multiplied by the number of items. Here, each "item" is 1 square foot of pool cover.

The truth value of the given proposition is "false".

The truth value of the given proposition can be evaluated using the following steps:

Convert the binary representation of the numbers to decimal:

0 = 0

~1 = -1 (invert the bits of 1 to get -2 in two's complement representation and add 1)

10 = 2

Apply the comparison operator "=" between the left and right sides of the equation:

(0 = -1) = 2

Evaluate the left side of the equation, which is false, because 0 is not equal to -1.

Evaluate the right side of the equation, which is true, because 2 is a nonzero value.

Apply the comparison operator "=" between the results of step 3 and step 4, which yields:

false = true

Therefore, the truth value of the given proposition is "false".

Answer:

-5

Step-by-step explanation:

We can see two points that the line intersects:

(0,2) and (1,-3)

‘From that we can find the slope:

\(\frac{y_2-y_1}{x_2-x_1} = \frac{-3-2}{1-0} = \frac{-5}{1} = -5\)

So, A.

:)

Answer:

-5

Step-by-step explanation:

Fast and loose: it's a negative number, since the line is decreasing, and it's decreasing faster than the diagonal of the II-IV quadrant (y=-x) so it's a number less than -1. Slope it's thus -5 or close to it.

More rigorous: start counting the squares. A slope of \(\frac ab\) tells you that every time you move vertically by a squares, you moved horizontally by b squares. Here to advance from 0 to 1 you went down from 2 to -3, ie you subtracted 5. Slope is -5

Honesty can be measured by asking people to rate themselves on a scale of 1-10 for honesty, ranking their fellow participants in terms of honesty, conducting a polygraph test to assess physiological responses when presented with specific questions, and conducting interviews to assess how forthright people are in their answers.

An operational definition of honesty can be measured by asking people to rate themselves on a scale of 1-10 for honesty. This would allow participants to self-assess their own level of honesty and provide a baseline for comparison. By observing how often people tell the truth in a given situation, one can measure the level of honesty of a person.

Additionally, a polygraph can be used to measure physiological responses when asking a series of specific questions. This can provide a more accurate measurement of a person’s honesty in comparison to a self-reported scale.

Lastly, conducting interviews with participants can help to assess how forthright people are in their answers. This allows for a more in-depth assessment of honesty by allowing interviewers to observe and assess the sincerity of participants’ answers.
