Answer:

51x-2=100

51x=102

x=2

So C is the answer

Answer:

C

Step-by-step explanation:

since the 2 lines are parallel, the angles with the intercepting line must be the same.

and the angles around the intercepting point are mirroring each other above and below the line.

so,

51x - 2 = 100

51x = 102

x = 2

A scientific hypothesis is a proposed explanation or prediction based on limited evidence or prior knowledge, which is subject to further investigation and testing.

A guess is a speculative, unsupported statement without any logical basis, whereas a hypothesis is an educated assumption derived from existing knowledge, observations, or theories. Unlike a guess, a hypothesis is testable and can be supported or refuted by evidence gathered through scientific methods.

Scientists need a hypothesis to provide a framework for their research and guide their investigations. It helps them define the specific question they want to answer and provides a starting point for designing experiments or making observations. By formulating a hypothesis, scientists can systematically evaluate and analyze data, ultimately leading to a deeper understanding of the phenomenon under investigation.

There are indeed scientific hypotheses that cannot be directly tested or proven due to practical or ethical constraints. For example, hypotheses related to historical events that occurred in the distant past may not have accessible evidence for direct testing. Additionally, some questions related to consciousness, subjective experiences, or philosophical concepts may lie beyond the scope of scientific inquiry, as they may not be objectively measurable or observable.

While science has its limitations, it is a powerful tool for investigating and understanding the natural world. However, there are questions that fall outside the realm of scientific inquiry and require other methods of investigation, such as philosophical or ethical considerations.

As the sample size increases, the t-distribution becomes more concentrated around the mean, and there is less uncertainty about the population mean.

The t-distribution is a probability distribution that is used in statistical inference to test hypotheses about the mean of a population when the sample size is small and the population standard deviation is unknown. The shape of the t-distribution depends on the degrees of freedom (df), which is determined by the sample size.

When the degrees of freedom are small, the t-distribution has more probability mass in the tails and is more spread out than when the degrees of freedom are large. As the degrees of freedom increase, the t-distribution approaches the standard normal distribution, which has zero mean and unit variance.

In this case, we are comparing the t-distributions for df = 4 and df = 20. Since df = 4 is smaller than df = 20, the t-distribution for df = 4 is flatter and more spread out than the t-distribution for df = 20. This means that the tails of the distribution are fatter and there is more variability in the data for df = 4 than for df = 20. In other words, when the sample size is small, there is more uncertainty about the population mean, and it is more likely that the sample mean will be farther away from the true population mean.

Answer:

B

Step-by-step explanation:

On a coordinate plane, parallel lines have the same slope as geometric figures are true. Thus option B is correct.

Marks, splines, spheres, and curved are used to build enclosed geometric shapes. We can see these shapes all around us. Illustrations of geometric shapes include circles, rectangles, triangles, and others. Any configuration of points, columns, or angles is a geometry figure.

A point is the most fundamental algebraic concept because it has no boundaries. Simply put, a point upon that plane is a location. A dot is used to symbolize it. A plane can be identified by three non-straight-line points.

As two or much more vectors seldom cross each other and are located on the same dimension, these are said to be parallel. The slope of these lines is constant. Coplanar lines that seem to be parallel are the ones that don't cross. Therefore, option B is the correct option.

The thickness of the clay layer, which drains only from the upper surface, can be determined based on the consolidation settlement observations. With 50% of consolidation settlement occurring in 1 hour for a 25 mm thick specimen, and a total primary consolidation settlement of 35 mm occurring over many years, the thickness of the clay layer is approximately 87.5 mm.

The consolidation settlement of a clay specimen can be used to estimate the thickness of a clay layer that drains only from the upper surface. In this case, the observed settlement data provides valuable information.

Firstly, we know that 50% of the consolidation settlement occurs in 1 hour for a 25 mm thick clay specimen. This is an important parameter for calculating the coefficient of consolidation (Cv) using Terzaghi's theory. From the Cv value, we can estimate the time required for full consolidation settlement.

Secondly, we are given that the same clay settles 10 mm over 10 years and eventually settles a total of 35 mm over a longer period. This long-term settlement is known as the total primary consolidation settlement. By comparing this settlement value with the settlement data from the oedometer test, we can determine the thickness of the clay layer.

To calculate the thickness, we can use the concept of the consolidation settlement ratio. The ratio of the total primary consolidation settlement to the consolidation settlement at 50% completion is equal to the ratio of the total thickness to the thickness at 50% completion. Applying this ratio, we can determine that the thickness of the clay layer, which drains only from the upper surface, is approximately 87.5 mm.

The integral does not converge to a finite value for any value of 'c'.

The given integral is:

∫[0, ∞] 15x x² (1 − 15c) 7x⁻¹ dx

Using this rule, we can integrate each term of the integral separately. Let's start with the first term:

∫ 15x x² dx = 15 ∫ x³ dx = (15/4) x⁴ + C1

Next, we can integrate the second term:

∫ (1 − 15c) 7x⁻¹ dx = (1 − 15c) 7 ∫ x⁻¹ dx = (1 − 15c) 7 ln(x) + C2

To find the value of the constant 'c', we need to evaluate the integral from 0 to infinity and set it equal to zero, as given in the problem:

∫[0, ∞] 15x x² (1 − 15c) 7x⁻¹ dx = 0

Substituting the values of the integrals, we get:

lim_(t→∞) ∫[0, t] 15x x⁻¹ (1 − 15c) 7x^(-1) dx = 0

lim_(t→∞) [ (15/4) t^4 − (1 − 15c) 7 ln(t) ] [0, t] = 0

Simplifying the expression, we get:

lim_(t→∞) [ (15/4) t^4 − (1 − 15c) 7 ln(t) ] = 0

Therefore, we can set the limit of the second term equal to infinity and solve for 'c':

lim_(t→∞) [ (1 − 15c) 7 ln(t) ] = ∞

(1 − 15c) lim_(t→∞) 7 ln(t) = ∞

lim_(t→∞) ln(t) = ∞

As we can see, the limit of ln(t) as t approaches infinity is infinity, so we can't solve for 'c' in this way.

7.393691004

Step-by-step explanation:

7.4 is the standard deviation from the following set of observation 20, 25, 30, 36, 32, 43​

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

The given data set is 20, 25, 30, 36, 32, 43​

Firstly we have to find the mean

Mean=20+25+30+36+32+43/6

=186/6

=31

The deviations from the mean are 20-31=-11

25-31=-6

30-31=-1

36-31=5

32-31=1

43-31=12

Using the definition of standard deviation (σ) , we have:

σ=√121+36+1+25+1+144/6

σ=√328/6

σ=√54.66=7.4

Hence, 7.4 is the standard deviation from the following set of observation 20, 25, 30, 36, 32, 43​

Step-by-step explanation:

brother or sister whoever you are, please try to post the full question.

a. The probability of success (hitting the target) is constant for each trial (88% or 0.88).

b. The probability of hitting the 6th target is:

P(X = 1) = C(1, 1) * 0.88^1 * (1 - 0.88)^(1 - 1) = 0.88

c. Using the binomial probability formula as before, with p = 0.88 and n = 3:

P(X = 1) = C(3, 1) * 0.88^1 * (1 - 0.88)^(3 - 1)

P(X = 2) = C(3, 2) * 0.88^2 * (1 - 0.88)^(3 - 2)

P(X = 3) = C(3, 3) * 0.88^3 * (1 - 0.88)^(3 - 3)

a) The three characteristics of this scenario that indicate we are working with Bernoulli trials are:

The experiment consists of a fixed number of trials (eight shots).

Each trial (shot) has two possible outcomes: hitting the target or missing the target.

The probability of success (hitting the target) is constant for each trial (88% or 0.88).

b) To find the probability of hitting the 6th target (considered as a single trial), we can use the binomial probability formula:

P(X = k) = C(n, k) * p^k * (1 - p)^(n - k)

where:

P(X = k) is the probability of getting exactly k successes,

C(n, k) is the binomial coefficient or number of ways to choose k successes out of n trials,

p is the probability of success in a single trial, and

n is the total number of trials.

In this case, k = 1 (hitting the target once), p = 0.88, and n = 1. Therefore, the probability of hitting the 6th target is:

P(X = 1) = C(1, 1) * 0.88^1 * (1 - 0.88)^(1 - 1) = 0.88

c) To find the probability that the first time hitting the target is not until the 4th shot, we need to consider the complementary event. The complementary event is hitting the target before the 4th shot.

P(not hitting until the 4th shot) = P(hitting on the 4th shot or later) = 1 - P(hitting on or before the 3rd shot)

The probability of hitting on or before the 3rd shot is the sum of the probabilities of hitting on the 1st, 2nd, and 3rd shots:

P(hitting on or before the 3rd shot) = P(X ≤ 3) = P(X = 1) + P(X = 2) + P(X = 3)

Using the binomial probability formula as before, with p = 0.88 and n = 3:

P(X = 1) = C(3, 1) * 0.88^1 * (1 - 0.88)^(3 - 1)

P(X = 2) = C(3, 2) * 0.88^2 * (1 - 0.88)^(3 - 2)

P(X = 3) = C(3, 3) * 0.88^3 * (1 - 0.88)^(3 - 3)

Calculate these probabilities and sum them up to find P(hitting on or before the 3rd shot), and then subtract from 1 to find the desired probability.

Answer:

3.06 cm^2/sec

Step-by-step explanation:

Since the shape is a cube, all sides have equal lengths, 6 cm  The rate of increase of 0.025cm/s [Note: I assume the unit should be cm/s, not cms'].

See the attached spreadsheet calculation.  Starting at time = 0 sec, the initial area is 36 cm^2.  Each second adds 0.025 cm to each side length,.

We can express this change in length as an equation:

Initial Length (6cm) + (x seconds)*(0.025 cm/s)

So for 10 second, l = 6 cm + 0.25cm or 6.25cm

--

The area is also changing with time.  At 0 seconds, the area is (6cm)^2 or 36 cm^2.  At 10 seconds, the area is (6.25cm)*(6.25cm) or 39.06 cm^2.

The area increased from 36 cm^2 to 39.06 cm^2 in 10 seconds.  That is a change rate of ((39.06 - 36 cm^2)/(10 sec):

 ((39.06 - 36 cm^2)/(10 sec)

 ((3.06 cm^2)/(10 sec)

3.06 cm^2/sec
