Graph ​y=−4/7x+1​.

Use the line tool and select two points on the line to graph the line.

Answer:

Step-by-step explanation:

Use the distance formula:

\(d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\) For us that will look like this:

\(d=\sqrt{(6-(-3))^2+(-2-4)^2}\) which simplifies to

\(d=\sqrt{(9)^2+(-6)^2}\) and a bit more to

\(d=\sqrt{81+36}\) so

\(d=\sqrt{117}\)

Let A be the event that we choose an adult chaperone and let B be the event that we pick a male student. Then, we want to calculate the following probability.

where the symbol between A and B means the union of events, which could be understood as "or". Using the properties of probability, we have

where the symbol on the right, between A and B, is the intersection, which can be understood as "and". Since we are going to pick only one person, it is impossible that we pick an adult chaperona and a male student. So,

So we have

Now, we want to calculate P(A) and P(B).

To calculate the probability of each event, we first count the number of possibilities that the event is true.

Note that since we have 6 adult chaperones, we have 6 possibilites such that the event A is true. Now, to calculate the probability of A, we simply divide this number by the total number of people on the bus (which is 50). So we get

In the same manner, for event B, we have a total of 23 possibilities such that the event B is true. Then

Finally, by replacing this values in the original expression, we have

The correct option regarding the scale factor and the statement in this problem is given as follows:

D. The statement is false. Because there are 3 feet in one​ yard, there are 9 square feet in one square yard.

The scale factor between the length dimensions of the yard are given as follows:

3 feet = 1 yard.

(as these length dimensions are given in yards).

Then for the square units, the correct scale factor is found applying the proportion as follows:

(3 feet)² = (1 yard)².

9 feet squared = 1 square yard.

Hence the statement given in this problem, that because there are 3 feet in one​ yard, there are also 3 square feet in one square yard, is false, and the correct option is given by option D.

The partial derivatives of ∂∂ and ∂∂ using implicit differentiation of (TU-V)2ln(W-UV)=ln(7) at (T,U,V,W)= (2,3,7,28) are:

∂f/∂T = -8/9

∂f/∂U = -10/27

∂f/∂V = 1/27

∂f/∂W = -8/81.

Let the given function be f(T,U,V,W) = (TU - V)²ln(W - UV) - ln(7).

Using the chain rule, we obtain the following expressions:

∂f/∂T = [2(TU - V)

ln(W - UV) + (TU - V)² / (W - UV) (-U)] / (TU - V)²

∂f/∂U = [2(TU - V)

ln(W - UV) + (TU - V)² / (W - UV) (-T)] / (TU - V)²

∂f/∂V = [2(TU - V)ln(W - UV) - (TU - V)²] / (TU - V)²

∂f/∂W = [2(TU - V)ln(W - UV) + (TU - V)² / (W - UV) (-U)] / (W - UV)at (T,U,V,W)

= (2,3,7,28),

we have:

Step-by-step explanation:

Dacia asks Katarina to tell her what the values of y are that can make sin θ negative. The correct answer is: "For y values greater than or equal to zero.

In the first quadrant (0 < θ < π/2), all trigonometric functions are positive.

In the second quadrant (π/2 < θ < π), only the sine is positive.

In the third quadrant (π < θ < 3π/2), only the tangent is positive.

Finally, in the fourth quadrant (3π/2 < θ < 2π), only the cosine is positive.

Therefore, sin θ is negative in the 3rd and 4th quadrants. In other words, for values of θ where sin θ is negative, you should look for θ values that fall in the 3rd and 4th quadrants.

Therefore, when Katarina responds to Dacia, "For y values greater than or equal to zero," it is incorrect as for the negative values of sin, θ must fall in the 3rd and 4th quadrants.

Thus, we cannot reject the null hypothesis and cannot conclude that there is a significant difference in the mean prices.

Based on the given information, we can compare the mean price of hotel rooms in Atlanta and Houston using their respective population standard deviations ($15 for Atlanta and $20 for Houston).

To determine if the mean price in Atlanta is lower than in Houston, we would conduct a hypothesis test.

The null hypothesis (H0) is that the mean price in Atlanta is greater than or equal to the mean price in Houston.

The alternative hypothesis (H1) is that the mean price in Atlanta is lower than the mean price in Houston.

To perform the hypothesis test, we would need the sample data from the Hotel file and calculate the sample means for both cities.

Using the sample means and the population standard deviations, we can calculate the test statistic and compare it to a critical value or find the p-value.

If the test statistic falls in the rejection region or the p-value is less than the significance level (usually 0.05), we can reject the null hypothesis and conclude that the mean price of a hotel room in Atlanta is lower than one in Houston.

If a shoe size of 7 is added to the data the IQR remains the same 2. Option D is the correct answer.

The interquartile range (IQR) in descriptive statistics is a measurement of statistical dispersion, or the spread of the data. The IQR is also known as the middle 50%, the fourth spread, or the H-spread. The difference between the data's 75th and 25th percentiles is how it is defined.

By using linear interpolation, the data set is separated into quartiles, or four rank-ordered even sections, to determine the IQR.

The shoe size in increasing order are written as:

5,5.5,6,6.5,6.5,7,7.5,8,8.5

The median of the data is:

Median = 5th value

Median = 6.5

The IQR of the data is given as:

IQR = Q2 - Q1

IQR = (7.5 + 8)/ 2 - (5.5 + 6) / 2

IQR = 2

When 7 is added to the data, the new order is:

5,5.5,6,6.5,6.5,7,7,7.5,8,8.5

The median of the new data is:

Median = 5th + 6th value/ 2

Median = (6.5 + 7)/2 = 6.75

The IQR of the data is given as:

IQR = Q2 - Q1

IQR = (7.5 + 8)/ 2 - (5.5 + 6) / 2

IQR = 2

Ruchi is incorrect because 2.81×10⁴ is around 30,000. so the units must be smaller than feet.

Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.

As it is given that the measurement that Ruchi wrote is 2.81×10⁴ ft². And, the area of 2.81×10⁴ ft² is 28,100 ft² which is nearly 30,000 ft², while the size of an average house is 2,300 ft². Therefore, the area that is written by Ruchi is too big compared to an average kitchen.

The expected value of the area of t is 1/12.

The length of the hands of the clock is 1. If a time of day is chosen uniformly at random, what is the expected value of the area of t?

The area of the triangle is given by the formula

A=1/2 ab sinC.

Here, we use Law of cosines to determine the angle C, which is enclosed by the hour and minute hands.

\((\cos C)_{h,m}=\frac{h^2+m^2-1}{2hm}\)

So, we can write the expected value of the area of t as

\(\begin{aligned}E[A]&=\int_{0}^{2\pi}\frac{1}{2}(1)(1)sinC\left(\frac{1}{12}+\frac{1}{720}((Cos C)_{h,m})^2\right)dC \\ &=\frac{1}{24\pi}\int_{0}^{2\pi}(sinC+sin(11C))dC \\ &=\frac{1}{12}\end{aligned}\)

Increasing marginal productivity infers that extra units of capital and labor contribute more to yield, driving productive asset allotment. ∝ and ß < 1 expect reducing returns, adjusting with reality.

To appear that the generation work has to expand the marginal productivity of capital (in case ∝ > 1) and labor (on the off chance that ß > 1), we ought to take fractional subsidiaries with regard to each input calculation. For capital (K), the fractional subsidiary of the generation work is:

\(\dfrac{dy}{dK }= \alpha AK^{(\alpha-1)}L^\beta\)

Since ∝ > 1, (∝ - 1) is positive, which implies that the fractional subordinate \(\dfrac{dy}{dK}\) is positive. This shows that an increment in capital input (K) leads to an increment in yield (y), appearing to expand the marginal efficiency of capital.

Additionally, for labor (L), the fractional subordinate of the generation work is:

\(\dfrac{dy}{dL} = \beta AK^{\alpha}L^{(\beta-1)}\)

Since \(\mathbf{\beta > 1, (\beta-1)}\) it is positive, which implies that the halfway subordinate \(\dfrac{dy}{dL}\) is positive. This demonstrates that an increment in labor input (L) leads to an increment in yield (y), appearing to increase the marginal productivity

The economic importance of increasing marginal productivity is that extra units of capital and labor contribute more to yield as their amounts increment.  This suggests that the more capital and labor a firm employments, the higher the rate of increment in yield. This relationship is vital for deciding the ideal assignment of assets and maximizing generation effectiveness.

In most generation capacities, it is accepted that ∝ and ß are less than 1. This presumption adjusts with experimental perceptions and financial hypotheses.

In case ∝ or ß were more prominent than 1, it would suggest that the marginal efficiency of the respective factor increments without bound as the calculated input increments.

In any case, there are decreasing returns to scale, which suggests that as calculated inputs increment, the Marginal efficiency tends to diminish. Therefore, accepting ∝ and ß are less than 1 permits for more reasonable modeling of generation forms and adjusts with the concept of diminishing marginal returns.
