Answer:

15.65 foot

Step-by-step explanation:

Pythagoras theorem can be used

a² + b² = c²

a being 14
b being unknown ( x )
c being 21

hence,

14² + x² = 21²
196 + x² = 441

x = √245  

  = 15.65 foot (answer)

Step-by-step explanation:

Slope-intercept form: y = mx + b

Solve for \(\frac{y2-y1}{x2-x1}\)

\(y2-y1 = \frac{11}{12} -\frac{19}{20}\)

\(x2-x1 = \frac{1}{3} -\frac{2}{5}\)

To solve for the fractions you need a common denominator.

\(y2-y1 = \frac{11*20}{12*20} -\frac{19*12}{20*12} = \frac{220}{240} -\frac{228}{240}=\frac{-8}{240} = \frac{-1}{30}\)

\(x2-x1 = \frac{1*5}{3*5} -\frac{2*3}{5*3} = \frac{5}{15} -\frac{6}{15}=\frac{-1}{15}\)

To divide fractions you keep (the first equation), change (the division sign to multiplication), and flip (the second fraction).

\(\frac{y2-y1}{x2-x1}=\frac{\frac{-1}{30} }{\frac{-1}{15} } = \frac{-1}{30}*\frac{15}{-1} =\frac{-15}{-30}=\frac{1}{2}\)

\(\frac{11}{12}\) = (\(\frac{1}{2}\))*(\(\frac{1}{3}\))+b

\(\frac{11}{12}\) = (\(\frac{1}{6}\))+b

\(\frac{11}{12}-\frac{1}{6}\) = b

\(\frac{11*6}{12*6}-\frac{1*12}{6*12}=\frac{66}{72} -\frac{12}{72} =\frac{54}{72}=.75\)

b = .75

y = \(\frac{1}{2}+.75\)

The slope of the tangent line to the polar curve r = 2 - sin(θ) at the point specified by θ = π/3 is √3.

To find the slope of the tangent line, we need to convert the polar equation to Cartesian coordinates. The conversion formulas are:

x = r * cos(θ)

y = r * sin(θ)

For the given polar curve r = 2 - sin(θ), substituting these formulas, we get:

x = (2 - sin(θ)) * cos(θ)

y = (2 - sin(θ)) * sin(θ)

To find the slope of the tangent line at θ = π/3, we need to differentiate both x and y with respect to θ and then calculate dy/dx.

dx/dθ = -(2 - sin(θ)) * sin(θ) - cos(θ) * cos(θ)

dy/dθ = (2 - sin(θ)) * cos(θ) - sin(θ) * cos(θ)

Now, we substitute θ = π/3 into these expressions:

dx/dθ = -(2 - sin(π/3)) * sin(π/3) - cos(π/3) * cos(π/3)

dy/dθ = (2 - sin(π/3)) * cos(π/3) - sin(π/3) * cos(π/3)

After evaluating these expressions, we can calculate dy/dx to find the slope of the tangent line at θ = π/3, which is √3.

Answer: remainder

Step-by-step explanation:

The simplified expression of cos^2x sin^4x is cos^2x - 2cos^4x + cos^6x.

The expression cos^2x sin^4x can be simplified by using the trigonometric identity that states sin^2x + cos^2x = 1.

We can rewrite cos^2x sin^4x as cos^2x (sin^2x)^2. Then, using the trigonometric identity sin^2x + cos^2x = 1, we can substitute (1 - cos^2x) for sin^2x.

This gives us cos^2x (1 - cos^2x)^2, which can be expanded using the binomial theorem to give cos^2x (1 - 2cos^2x + cos^4x).

Finally, we can simplify this expression further by distributing the cos^2x term and collecting like terms to get cos^2x - 2cos^4x + cos^6x.

Therefore, the simplified expression of cos^2x sin^4x is cos^2x - 2cos^4x + cos^6x.

Answer:

11:27 am.

Step-by-step explanation:

The time which has passed when Tom overtakes Hazel is after Hazel has walked 1 hr 15 minutes and in that time Hazel has walked

1.25 * 4.8

= 6 km.

So, Tom runs 6 km in 10:15 - 9.39 = 36 minutes

= 0.6 hrs.

So, Tom's speed is 6/0.6 = 10 km/hr.

,

and Tom will take 18/10 = 1.8 hours to finish the route,

= 1 hr 48 minutes

So he finishes the route at

9:39 + 1:48

= 11:27 am.

calculate the lengths using the distance formula

d = \(\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }\)

with (x₁, y₁ ) = J (- 3, - 7 ) and (x₂, y₂ ) = K (3, - 8 )

JK = \(\sqrt{(3-(-3))^2+(-8-(-7))^2}\)

    = \(\sqrt{(3+3)^2+(-8+7)^2}\)

    = \(\sqrt{6^2+(-1)^2}\)

    = \(\sqrt{36+1}\)

The regression formula estimated when performing a test for the stationarity of a time series variable y is y(t) = α + β*t + ε(t).

a. The null hypothesis of this test is that the time series variable y is non-stationary, meaning it has a unit root.

b. To determine whether two variables are cointegrated, the following steps are typically involved:

1) Identify the two variables: Select two time series variables, denoted as X(t) and Y(t), that are suspected to be related in a long-run equilibrium.

2) Test for unit roots: Conduct unit root tests on both X(t) and Y(t) to determine if they are stationary.

3) Estimate the cointegration regression: If both variables are non-stationary, estimate the cointegration regression model, typically using methods like the Engle-Granger two-step procedure or the Johansen test. This regression model takes the form Y(t) = α + β*X(t) + ε(t).

4) Test for the presence of a cointegrating relationship: Perform hypothesis tests on the estimated coefficients to check if the β coefficient is significantly different from zero, indicating the presence of a cointegrating relationship.

5) Interpret the results: If the null hypothesis of no cointegration is rejected, it suggests that X(t) and Y(t) are cointegrated, meaning they have a long-run relationship.

Cointegration analysis is used to determine whether two variables move together over time, despite being non-stationary individually. It helps in understanding the long-run equilibrium relationship between variables and can be valuable in modeling and forecasting.

The graduate student cannot reject the null hypothesis if the test statistic is not in the critical region, indicating insufficient evidence to conclude the effect of contrast on perceived femininity.

Based on the provided hypotheses and significance level, let's analyze the possible decisions the graduate student can make:

"There is enough evidence to reject the hypothesis that the contrast between lip color and skin tone does not affect how feminine a face is considered." - This decision would be made if the calculated test statistic falls into the critical region (beyond the critical value). This would lead to rejecting the null hypothesis and accepting the alternative hypothesis.

"There is not enough evidence to reject the hypothesis that the contrast between lip color and skin tone affects how feminine a face is considered." - This decision would be made if the calculated test statistic falls outside the critical region (within the non-critical region). In this case, there is insufficient evidence to reject the null hypothesis.

Given the scenario where the test statistic is not inside the critical region, the appropriate decision for the graduate student would be: "The graduate student cannot reject the null hypothesis." This means that based on the available data, there is not enough evidence to conclude that the level of contrast between lip color and skin tone affects how feminine a face is considered.

The statement regarding the test statistic and the boundary to the critical region seems incorrect. The test statistic of 2.59 exceeds the critical value of 1.96, indicating that it falls into the critical region. Therefore, the correct decision would be to "reject the null hypothesis" and conclude that the level of contrast between lip color and skin tone affects how feminine a face is considered.

There are 12 possible seating arrangement that Ali, Bonnie, Carlo, and Dianna can seat in a 4 seated car while visiting to a nearby theme park.

There are in total 4 people so the the possible seating arrangement should be 4! = 4*3*2 = 24.

But only 2 people know how to drive a car that is Bonnie and Carlo,

So the remaining seat can be occupied by any three that are remaining beside the driver.

So 3 remaining people can go in the front passenger seat.

There are 2 people who can go in the first back passenger seat.

The remaining person must go in the last seat.

Thus, there are 2x3x2 or 12 ways that they can be seated.

If 6 human resource managers are randomly selected, the probability that at least 2 of them say job applicants should follow up within two weeks is; 81.047%

The binomial probability is defined as the probability of exactly x successes on n repeated trials, with p probability

The general formula of binomial probability distribution is;

P(X = x) = ⁿCₓ * pˣ * (1 - p)⁽ⁿ ⁻ ˣ⁾

where;

p is probability of success

n is number of trials or sample size

x is number of successful trials

Thus,  If 6 human resource managers are randomly selected, the probability that at least 2 of them say job applicants should follow up within two weeks is;

P(X ≥ 2) = 1 - (P(0) + P(1))

P(0) = ⁶C₀ * 0.43⁰ * (1 - 0.43)⁽⁶ ⁻ ⁰⁾ = 0.0343

P(1) = ⁶C₁ * 0.43¹ * (1 - 0.43)⁽⁶ ⁻ ¹⁾ = 0.15524
