You are using an exponential smoothing model for forecasting. The running sum of the forecast error statistics (RSFE) is calcula

ted each time a forecast is generated. You find the last RSFE to be 34. Originally, the forecasting model used was selected because of its relatively low MAD of 0.4. To determine when it is time to re-evaluate the usefulness of the exponential smoothing model, you compute tracking signals. Which of the following is the resulting tracking signal?A) 85B) 60C) 13.6D) 12.9E) 8

Answer:

A)85

Step-by-step explanation:

Calculation for the resulting tracking signal

Using this formula

Tracking signal= Last forecast error statistics (RSFE) /Low MAD (Mean Absolute Deviation)

Let plug in the formula

Tracking signal=34/0.4

Tracking signal=85

Therefore the resulting tracking signal will be 85

Someone solve this please like NOW 4(5x-7)+12=16x+24
Bingel [31]

20x-28+12=16x+24 (i distributed the 4 to get this)

20x-16=16x+24 (added -28 & 12)

4x=40 (Subtracted 16x from both sides and added 16 to both sides)

(divide by 4 on both sides)

x=10

What is the difference between no solution and no real solution? When do you get multiple solutions? This is for solving absolut
shepuryov [24]
No solution means u can graph the two equations and it would form parallel lines and would never intersect while, no real solution when graph the two equations would form the same line. When dealing with absolute value equation an equation with a degree larger than one,theres a chance it can be multiple solutions

A circular window is drawn on architectural plans where each unit is a foot on a coordinate grid. the window is modeled by the e
Pie

The equation indicates that the center of the window is 12 feet from the ground and the distance the window spans 6 feet.

<h3>What is the general equation of a circle?</h3>

The equation of a circle is given by the formula,

(x-a)^{2} + (y -b)^{2} = r^{2}

where (a,b) is the coordinate of the center of the circle, and r is the radius of the circle.

According to the given equation, if we compare this equation with the general equation of the circle.

(x-4)^{2} + (y-12)^{2} = 9

(x-a)^{2} + (y -b)^{2} = r^{2}

(x-4)^{2} + (y -9)^{2} = 3^{2}

On  observing this equation we will get that the value of (a,b) is (4,12).

Thus, The equation indicates that the center of the window is 12 feet from the ground

window span = diameter of circle

window span = 2r

= 2 × 3 (radius = 3)

= 6

Hence, The equation indicates that the center of the window is 12 feet from the ground and the distance the window spans 6 feet.
