Answer written in standard form:

2x + 3y = -4

9514 1404 393

Answer:

  2x +3y = -4

Step-by-step explanation:

The slope of the line is given by the slope formula:

  m = (y2 -y1)/(x2 -x1

  m = (-4 -4)/(4 -(-8)) = -8/12 = -2/3

This can be used in the point-slope formula to find an equation of the line:

  y -y1 = m(x -x1)

  y -4 = -2/3(x -(-8)) . . . . substituting for (x1, y1) and m

Multiplying by 3 eliminated fractions:

  3(y -4) = -2(x +8)

  3y -12 = -2x -16

Adding 2x+12 to both sides gives the standard form equation:

  2x +3y = -4

The probability that at least one of the specialists will detect tuberculosis in this person is 0.9999 or 99.99%.

To calculate the probability that at least one of the specialists will detect tuberculosis in this person, we can use the concept of the complement rule.Let's denote the probability that a specialist will detect tuberculosis as p. The probability that a specialist will not detect tuberculosis is then (1 - p).Since each specialist examines the x-ray independently, the probability that none of the specialists will detect tuberculosis is (1 - p) raised to the power of the number of specialists.Let's assume there are four specialists. The probability that none of them will detect tuberculosis is (1 - p)⁴.

Therefore, the probability that at least one of the specialists will detect tuberculosis is 1 minus the probability that none of them will detect tuberculosis.

Probability(at least one specialist detects tuberculosis) = 1 - Probability(none of the specialists detect tuberculosis)

= 1 - (1 - p)⁴

Substituting the given information that each specialist can detect tuberculosis % of the time when it is present (which means p = %/100), we can calculate the probability.

Probability(at least one specialist detects tuberculosis) = 1 - (1 - p)⁴

= 1 - (1 - %/100)⁴

For example, if each specialist has a 90% detection rate (% = 90), the probability would be:

Probability(at least one specialist detects tuberculosis) = 1 - (1 - 90/100)⁴= 1 - (1 - 0.9)⁴

= 1 - (0.1)⁴

= 1 - 0.0001

= 0.9999

Therefore, the probability that at least one of the specialists will detect tuberculosis in this person is 0.9999 or 99.99%.

In problem 1, an initial value problem is given with a first-order differential equation. The exact solution, y(t), is obtained, and Euler's method is used with different step sizes to obtain numerical solutions, u(t), at t=3.In problem 2, the second-order Runge-Kutta method (improved Euler's method) is applied to the same initial value problem. The numerical solution, v(t), is obtained at t=3 with h=0.1.

In problem 1, the initial value problem is solved analytically to obtain the exact solution, y(t). Euler's method is then applied with different step sizes (h) to approximate the solution numerically at t=3. The numerical solution, u(t), is plotted alongside the exact solution, y(t), to visualize their comparison. The error, e1, is calculated as the maximum absolute difference between u(t) and y(t) over the interval [0, 3]. By varying the step size and computing e1, the effect of the step size on the accuracy of the numerical solution can be observed.

In problem 2, the second-order Runge-Kutta method is employed to approximate the solution numerically. The numerical solution, v(t), is computed at t=3 with h=0.1 and compared to the exact solution, y(t), through a plot. The error, e2, is calculated as the maximum absolute difference between v(t) and y(t) over the interval [0, 3]. By computing e2 for different step sizes and comparing it to e1 from problem 1, the difference between the two numerical methods can be observed in terms of accuracy and convergence.

The number of hours it took from her house to the beach is 50.5 hour while The number of hours it took from her beach to the park is 60.5 hour.

What is the number of hours it took Elia from her house?

Given:  speed from house to the beach (Sb) = 181818 km/h, speed from the beach to park (Sp) = 151515 km/h and total duration(T) = 111 h.

Also, we are told the distances are the same. Let's represent that with the letter D

We are instructed to represent the number of hours it took Elia to ride from her house to the beach with bbb and the number of hours it took her to ride from the beach to the park with ppp.

From the information we can say:

bbb + ppp = T

bbb + ppp = 111

Also:  ppp = 111 - bbb

Using the formula for speed:

Speed = distance / time

Sp = D/ppp

151515 = D/ ppp

D = 151515 x ppp

Also:

Sb = D/ppp

181818 = D/ bbb

D = 181818 x bbb

Since the distances (D) are the same. We can equate the two distances:

181818 x bbb = 151515 x ppp

Put ppp = 111 - bbb:

181818 x bbb = 151515 x (111 - bbb)

181818bbb = 16818165 - 151515bbb

181818bbb + 151515bbb = 16818165

333333bbb = 16818165

bbb = 16818165/333333 = 555/11 hour = 50.5 hour

Put bbb = 555 into ppp = 111 - bbb:

ppp = 111 - 555/11  = 666/11 hour = 60.5 hour

Therefore, the number of hours it took her to ride from her house to the beach and the number of hours it took her to ride from the beach to the park are  50.5 hour and 60.5 hour respectively.

The sales trend Sales = 181.00 + 2t where t= time in quarters, beginning in Q1 2014The seasonal factors for the four quarters are i.e: {0.9, 1.1, 1.2, 0.8}

To find the seasonalized forecast for Q2 of 2017, the following steps must be followed:

Step 1: Calculate trend for the Q2 of 2017 t = 3.25

Step 2: Determine seasonal factor for Q2 which is 1.1 since it's the second quarter

Step 3: Multiply trend and seasonal factors to get seasonalized trend for Q2 = (181 + 2(3.25)) * 1.1 = 198.95

Step 4: Therefore, the seasonalized forecast for Q2 of 2017 is 198.95.

Therefore, we have Sales = 181.00 + 2t where t is the time in quarters, starting from Q1 2014. In other words, t = 1 for Q1 2014, t = 2 for Q2 2014, and so on.

In addition, we have seasonal factors for each quarter, i.e, {0.9, 1.1, 1.2, 0.8}.

To calculate the seasonalized forecast for Q2 of 2017, we need to follow the following steps:

Step 1: Calculate trend for the Q2 of 2017t = 3.25 [since there are 13 quarters between Q1 2014 and Q2 2017.

The 13th quarter corresponds to Q2 2017. So, t = 13. Therefore, t = 2 + 4(13 - 1) = 3.25]

Step 2: Determine the seasonal factor for Q2 of 2017

The seasonal factor for Q2 of 2017 = seasonal factor for the second quarter = 1.1

Step 3: Multiply trend and seasonal factors to get seasonalized trend for Q2

Therefore, seasonalized trend for Q2 of 2017 = (181 + 2(3.25)) * 1.1 = 198.95Step 4:

Therefore, the seasonalized forecast for Q2 of 2017 is 198.95.
