Answer:

2

Step-by-step explanation:

By the triangle proportionality theorem,

\( \frac{12}{2y - 1} = \frac{4y - 4}{1} \\ \\ 12 = (2y - 1)(4y - 4) \\ \\ 12 = 8 {y}^{2} - 12y + 4 \\ \\ 8 {y}^{2} - 12y - 8 =0 \\ \\2 {y}^{2} - 3 y - 2 = 0 \\ \\ (2y + 1)(y - 2) = 0\)

From this, we know that y = -1/2 or 2.

However, as distance must be positive, we disregard the negative case, giving us y = 2.

Answer:

y= -x+2

Step-by-step explanation:

If what they are asking for is slope-intercept format, then you need to isolate the y on one side.

So add -2x to both sides to get, -2y= 2x-4

After that you would divide both sides by -2, and when you do this you are dividing every single term by -2 so you would get,

y= -x+2

that is your slope- intercept formula.

so your slope is m= -1

Answer:

X-intercept: (2,0)

Y-intercept: (0,2)

Step-by-step explanation:

all it's asking for when it says "find the intercepts" is for two points, the one with 0 in the x position, and the one with 0 in the y position of the point (x,y).

These are surprisingly easy! Just plug 0 into x and solve for y. In this case, that gives us (-2)x(0)-2y = -4

Do some algebra and you'll find that y = 2. Since we plugged in 0 for x, that gave us the y-intercept: (0,2). (Remember, the y-intercept is when it intersects the y-axis. All points on the y axis have an X coordinate of 0!)

Now do the same thing but plug 0 in for y.

-2x - (2)x(0) = -4

-2x = -4

x=2

This gives us the x-intercept of (2,0)

Answer:

144

Step-by-step explanation:

The measure of arc DB from the given circle is 144°.

A circle is a two-dimensional figure formed by a set of points that are at a constant or at a fixed distance (radius) from a fixed point (center) on the plane. The fixed point is called the origin or center of the circle and the fixed distance of the points from the origin is called the radius.

From inscribed angle theorem, the measure of an inscribed angle is equal to half the measure of its intercepted arc.

That means that measure of arc AD that is 2x.

Since Ab is diameter of the circle, the measure of arc ADB is equal to 180 degree

Since the ratio of AD to DB is 1:4, the arc DB is 8x

Use the arc addition postulate to make a formula.

2x+8x=180°

Solve for x. Round the nearest tenth if necessary

10x=180°

c=18°

Now that you have solved for x, find the measure of are DB. Round to the nearest tenth if necessary.

measure of arc = 8x°

measure of area DB = 8×18°

= 144°

Therefore, the measure of arc DB from the given circle is 144°.

Answer:

All students have to take at least one math class and one language class. Twenty students take calculus, and thirty students take statistics.

(a)The amount of water in the tank is increasing.

(b)Evaluate  \(\int\limits^{18}_0(W(t) - R(t)) dt\) to get the number of gallons of water in the tank at t = 18.

(c)Solve part (b) to get the absolute minimum from the critical points.

(d)The equation can be set up as   \(\int\limits^k_{18}-R(t) dt = 1200\) and solve this equation to find the value of k.

What is the absolute value of a number?

The absolute value of a number is its distance from zero on the number line. It represents the magnitude or size of a real number without considering its sign.

To solve the given problems, we need to integrate the given rates of water flow to determine the amount of water in the tank at various times. Let's go through each part step by step:

a)To determine if the amount of water in the tank is increasing at time t = 15, we need to compare the rate of water being pumped in with the rate of water being removed.

At t = 15, the rate of water being pumped in is given by \(W(t) = 95Vt sin^2(\frac{t}{6})\) gallons per hour. The rate of water being removed is \(R(t) = 275 sin^2(\frac{1}{3})\) gallons per hour.

Evaluate both rates at t = 15 and compare them. If the rate of water being pumped in is greater than the rate of water being removed, then the amount of water in the tank is increasing. Otherwise, it is decreasing.

b) To find the number of gallons of water in the tank at time t = 18, we need to integrate the net rate of water flow from t = 0 to t = 18. The net rate of water flow is given by the difference between the rate of water being pumped in and the rate of water being removed. So the integral to find the total amount of water in the tank at t = 18 is:

\(\int\limits^{18}_0(W(t) - R(t)) dt\)

Evaluate this integral to get the number of gallons of water in the tank at t = 18.

c)To find the time t when the amount of water in the tank is at an absolute minimum, we need to find the minimum of the function that represents the total amount of water in the tank. The total amount of water in the tank is obtained by integrating the net rate of water flow over the interval [0, 18] as mentioned in part b. Find the critical points and determine the absolute minimum from those points.

d. For t > 18, no water is pumped into the tank, but water continues to be removed at the rate R(t) until the tank becomes empty. To find the value of k, we need to set up an equation involving an integral expression that represents the remaining water in the tank after time t = 18. This equation will represent the condition for the tank to become empty.

The equation can be set up as:

\(\int\limits^k_{18}-R(t) dt = 1200\)

Here, k represents the time at which the tank becomes empty, and the integral represents the cumulative removal of water from t = 18 to t = k. Solve this equation to find the value of k.

To estimate an individual's probability using a linear probability model, fit the model with the binary dependent variable and explanatory variables, obtain coefficient estimates, and calculate the probability using the individual's values and the model equation.

1. Set up your data:

  - Make sure you have a dataset that includes your binary dependent variable (usually coded as 0 and 1) and the explanatory variables (also known as independent variables or predictors).

2. Fit a linear probability model:

3. Obtain coefficient estimates:

4. Calculate the individual's probability:

It's important to note that the linear probability model assumes a constant effect of explanatory variables on the probability, which can lead to predicted probabilities outside the range of 0 to 1. Additionally, heteroscedasticity (unequal variance) and potential issues with interpretation may arise with this model.

Regarding the specific commands for reviews, it would depend on the software or programming language you are using. The command for calculating the cumulative standard normal distribution (cnorm) you mentioned is specific to the probit model, not the linear probability model. For the linear probability model, you would typically use regression functions available in the chosen software, such as `lm()` in R or the appropriate regression function in Python's statsmodels library, to estimate the model and obtain the coefficient estimates.

The value of the triple integral ∭E​2xdV over the region E is π.

We have,

To evaluate the triple integral ∭E​2xdV, where E is bounded by the paraboloid x = y² + z² and the plane x = 1, we need to determine the limits of integration.

The plane x = 1 intersects the paraboloid x = y² + z² when x = 1.

Substituting x = 1 into the paraboloid equation gives:

1 = y² + z²

This equation represents a circle in the yz-plane with a radius of 1.

So, we can express the bounds for y and z as follows:

-1 ≤ y ≤ 1

-√(1 - y²) ≤ z ≤ √(1 - y²)

For the x-coordinate, since we are integrating over the entire region between the paraboloid and the plane, the limits are 0 ≤ x ≤ 1.

Now, we can set up the triple integral:

∭E​2xdV = ∫[0,1]∫[-1,1]∫[-√(1 - y²), √(1 - y²)] 2x dz dy dx

Integrating with respect to z first:

∭E​2xdV = ∫[0,1]∫[-1,1] [2xz] evaluated from -√(1 - y²) to √(1 - y²) dy dx

Simplifying:

∭E​2xdV = ∫[0,1]∫[-1,1] 2x(√(1 - y²) - (-√(1 - y²))) dy dx

∭E​2xdV = ∫[0,1]∫[-1,1] 4x√(1 - y²) dy dx

Now, integrating with respect to y:

∭E​2xdV = ∫[0,1] [4x(π/2)] dx

∭E​2xdV = 2π∫[0,1] x dx

∭E​2xdV = 2π[x²/2] evaluated from 0 to 1

∭E​2xdV = 2π(1/2 - 0) = π

Therefore,

The value of the triple integral ∭E​2xdV over the region E is π.

Step-by-step explanation:

The equation used to find the distance of the flowerbed from the hive is called the "time equation".

The flowerbed is 900 feet far from the hive.

Find the traveling time

The bee spends 12 minutes hunting down the nectar in the flowerbed. Since it was away from the hive for a total of 16 minutes, the traveling time is

16min - 12min = 4 min

Convert the Minutes to seconds

1 minute = 60 seconds

4 minutes = 4*60 = 240 seconds

Find the time each way

The total time is 240 seconds, but it is not divided evenly.

Let the time there = t

Let the time back = 240 - t

The distances are the same

r = 10 m/s

r1 = 6 m/s

t1 = t

t2 = 240 - t

dthere = dback

d = rate * time

10 m/s *t = 6 m/s (240 - t)      

Remove the brackets on the right.

10 * t = 6*240 - 6t                

Combine the like terms on the right.

10t = 1440 - 6t                        

Add 4t to both sides

10t + 6t = 1440 - 6t + 6t          

Combine

16t = 1440                            

Divide both sides by 16

16t/16 = 1440/16                    

Do the division

t = 90                                    

Find the height

d = ?

r = 10 m/s

t = 90 second

d = r*t

d = 10 * 90 = 900 feet

Yes, these data support the scientist's belief that large islands are more effective at protecting at-risk species than small islands. To provide statistical justification, we can compare the probability of extinction for each island size: For large islands, the probability of extinction is 19/208, or approximately 0.091. For small islands, the probability of extinction is 66/299, or approximately 0.221.

The data provided can support the scientist's belief that large islands are more effective than small islands for protecting at-risk species. We can use the concept of probability to calculate the likelihood of extinction for both large and small islands.

For the large island, the probability of extinction for any given species is 19/208 or approximately 0.091. For the small island, the probability of extinction for any given species is 66/299 or approximately 0.221.

Comparing these probabilities, we see that the probability of extinction is higher for at-risk species on small islands than on large islands. This supports the scientist's belief that large islands are more effective for protecting at-risk species.

Additionally, we can use statistical tests such as a chi-square test or a two-sample t-test to confirm whether the difference in extinction rates between large and small islands is statistically significant.

These tests would require more information such as sample size and variance, but based on the provided data alone, the probability calculations suggest that the scientist's belief is supported.

a. The number of employees of bus transportation users who are late to come to the office for one month does not have a Poisson distribution. The Poisson distribution models the number of events occurring in a fixed interval of time or space, with the assumption of a constant rate of occurrence and events being independent. In this case, the number of late employees is not likely to follow a Poisson distribution because it may depend on various factors such as traffic conditions, individual circumstances, and other external factors.

b. The number of short messages received in one week does not necessarily follow a Poisson distribution. The Poisson distribution is typically used to model rare events occurring in a fixed interval of time or space. The number of messages received in a week may not meet the criteria of a constant rate of occurrence or independence. Factors such as popularity, communication habits, and individual circumstances can influence the number of messages received.

c. The number of ships leaning on Tanjung Perak Port does not have a Poisson distribution. The arrival and departure of ships at a port are influenced by various factors, including shipping schedules, cargo demand, weather conditions, and operational constraints.
