Answer:

10%

Step-by-step explanation:

To get 0.2 from 2, we need to divide by 10 or multiply by 0.10. Since we have 0.10, we convert that to percent by multiplying by 100 to get 10%.

Answer:

0.2 is 10% of 2.

Step-by-step explanation:

We can set up an equation:

2*x=0.2

x is representing the decimal that 2 needs to be multiplied to equal 0.2

2x=0.2

x=0.1

If x equal 0.1, then we can convert 0.1 into a percent. 0.1=10%

So, 0.2 is 10% of 2.

The length of the garden is 99 m.

The formula for the area of a rectangle is:

Area = Length x Width

We are given that the area of the rectangle is 8811 \(m^{2}\) and the width is 89 m. Substituting these values into the formula, we get:

8811 \(m^{2}\) = Length x 89 m

To solve for the length, we can divide both sides of the equation by 89 m:

Length = 8811 \(m^{2}\) / 89 m

Simplifying, we get:

Length = 99 m

Therefore, the length of the garden is 99 m.

It will cost $1186.5 to fence the given garden which is in shape of right angled triangle.

Perimeter is the sum of boundary sides of the given figure. Generally, perimeter is calculated by adding all the sides of the figure given.

To find the cost of fencing the given garden, which is in shape of a right -angle triangle, firtsly we have to find the primeter of triangle.

Two shorter sides of the triangle are 24m and 7 m.

To find the third side of thye triangle which is also known as hypotenuse we have to apply the pythagoras theorem,

Third side (hypotenuse) = \(\sqrt{7^2+24^2} =\sqrt{49+576} =\sqrt{625} =25m\).

Now the perimeter of the given triangle=24+7+25=56m.

fencing comes in 4m section.

so, for fencing the garden we will need,

\(=\frac{56}{4} =14 sections\).

Cost of one section=$75 + tax (13%).

Cost of one section=$84.75

Cost of 13 sections = 14 x $84.75 = $1186.5.

The probability of choosing an action or a comedy out of seven action movies, five comedies, and three dramas is 4/5.

What is probability?

Probability defines the likelihood of occurrence of an event. There are many real-life situations in which we may have to predict the outcome of an event.

The probability of an event can be calculated by probability formula by simply dividing the favorable number of outcomes by the total number of possible outcomes.

According to the given question:

In the movie drawer, there are 15 movies, seven are action movies, five comedies, and three dramas.

The probability of choosing an action movie = 7/15

While the probability of choosing a comedy movies = 5/15

The probability of choosing an action or a comedy

= (7/15+5/15)

=12/15

= 4/5

Therefore the probability of choosing an action or a comedy out of seven action movies, five comedies, and three dramas is 4/5

The values of the missing angles and sides after dilation are:

m∠C'B'D' = 95°,  CQ = 6 and  B'D' = 11.

m∠C'B'D = 180° - m∠B'C'D' - m∠B'D'C'

m∠B'C'D = m∠BCD, m∠B'D'C' = m∠BDC  (dilation)

m∠C'B'D = 180° - 34° - 51° = 95°

Thus, by way of scale factor we can say that:

BC/B'C' = BD/B'D' = 36/18 = 2

B'D' = ¹/₂BD = ¹/₂ * 22 = 11

Answer:

9 hours

Step-by-step explanation:

The time taken is inversely proportional to the number of men; if M = number of men and D = number of days this can be expressed as
\(D \displaystyle \propto } \dfrac{1}{M}\\\\\text{which can be expressed as an equation: }\\\\D = k \cdot \dfrac{1}{M}\\\\or\\\\D = \dfrac{k}{M}\\\\\)

k is known as the constant of proportionality which can be expressed as

\(k = D\cdot M\)

Inversely proportional means:
As the number of men increases, the time taken decreases

As the number of men decreases, the time taken  increases

We can find k from the given information with M = 3 and D = 6 hours

\(k = 6 \cdot 3 = 18\)

\(\textrm{Therefore, given M= 2, D = $\dfrac{18}{2} = 9$ \;hours}\)

For 2 men it will take 9 hours to repair the road

The probability that the sample mean will be greater than 57.95 is 0.0495.

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. This is the basic probability theory, which is also used in the probability distribution.

To solve this question, we need to know the concepts of the normal probability distribution and of the central limit theorem.

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:

\(Z=\dfrac{X-\mu}{\sigma}\)

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

The Central Limit Theorem establishes that, for a random variable X, with mean \(\mu\) and standard deviation \(\sigma\), a large sample size can be approximated to a normal distribution with mean \(\mu\) and standard deviation \(\frac{\sigma}{\sqrt{\text{n}} }\).

In this problem, we have that:

The probability that the sample mean will be greater than 57.95

This is 1 subtracted by the p-value of Z when X = 57.95. So

\(Z=\dfrac{X-\mu}{\sigma}\)

By the Central Limit Theorem

\(Z=\dfrac{X-\mu}{\text{s}}\)

\(Z=\dfrac{57.95-53}{3}\)

\(Z=1.65\)

\(Z=1.65\) has a p-value of 0.9505.

Therefore, the probability that the sample mean will be greater than 57.95 is 1-0.9505 = 0.0495

The dx2−y2 orbital in the n=5 shell will have a higher principal quantum number (n=5) than the dx2−y2 orbital in the n=3 subshell (n=3). This means that the contour of the orbital in the n=5 shell will extend further along the x and y axes, as the orbital size increases with increasing n.

However, the mℓ value will remain the same, as the angular momentum quantum number (ℓ) remains constant at two and mℓ can only take values between -ℓ and +ℓ.

The problem of unit root in standard regression and time-series models arises when a variable exhibits a non-stationary behavior, meaning it has a trend or follows a random walk. Unit root tests, such as the Dickey-Fuller and augmented Dickey-Fuller tests, are used to detect the presence of a unit root in a time series. These tests examine whether the coefficient on the lagged value of the variable is significantly different from one, indicating the presence of a unit root.

In standard regression analysis, it is typically assumed that the variables are stationary, meaning they have a constant mean and variance over time. However, many economic and financial variables exhibit non-stationary behavior, where their values are not centered around a fixed mean but instead follow a trend or random walk. This presents a problem because standard regression techniques may produce unreliable results when applied to non-stationary variables.

Time-series models, such as autoregressive integrated moving average (ARIMA) models, are specifically designed to handle non-stationary data. They incorporate differencing techniques to transform the data into a stationary form, allowing for reliable estimation and inference. Differencing involves computing the difference between consecutive observations to remove the trend or random walk component.

The Dickey-Fuller test and augmented Dickey-Fuller test are commonly used to detect the presence of a unit root in a time series. These tests examine the coefficient on the lagged value of the variable in a regression framework. The null hypothesis of the tests is that the variable has a unit root, indicating non-stationarity, while the alternative hypothesis is that the variable is stationary.

The Dickey-Fuller test is a simple version of the test that includes only a single lagged difference of the variable in the regression. The augmented Dickey-Fuller test extends this by including multiple lagged differences to account for potential serial correlation in the data. Both tests provide critical values that can be compared to the test statistic to determine whether the null hypothesis of a unit root can be rejected.

a) To get how far from the base of the cliff does the ball land, we will use the SOH CAH TOA identity.

\(tan \theta =\frac{opposite}{adjacent}\\tan40^0=\frac{60}{x} \\x=\frac{60}{tan40^0}\\x=\frac{60}{0.8391}\\x= 71.5m\)

This shows that the ball land 71.5m away from the base of the cliff.

b) The time the ball used in the air is the time of flight and it is expressed as:

\(T=\frac{2usin\theta}{g}\\T=\frac{2(90)sin40^0}{9.81}\\T=\frac{180(0.6428)}{9.81}\\T=\frac{115.704}{9.81}\\T= 11.794s\)

The answer to whether Dr. Reyes can make a causal inference from the study is;

No, she can't make a casual inference from the study because she met only one of the three criteria's for causality.

Now, the three conditions are;

1) Covariation; This condition means that the causal variable must have to vary with with the variable it is assumed to cause in a systematic manner.

2) Temporal precedence; Thus condition simply means that cause must precede effect. In summary it denotes that the variable that has the causal effect must come before the effect that it is meant to cause.

3) Control for extraneous variables; This condition means that results of an experiment or research must not be due to factors outside of the experiment/research

     Now, in our question, he fulfilled the covariation condition because the

result of the research is tied to the responses from the sample students.

However, she did not fulfill the temporal precedence because the cause of

their moods did not precede the effects in his research.

Also, she did not fulfill the condition of control of extraneous variables

because other factors outside of the research itself may have affected their
