Answer:

By using 3-month weighted moving average method -

Forecasts for the 4th month = 5400

Forecasts for the 5th month = 5530

By using Exponential smoothing method -

Forecasts for 3rd month = 5300

Forecast for 4th month = 5350

Forecast for  5th month = 5475

Step-by-step explanation:

To find - Calculate the forecasts for the 4th and 5th months using 3-month weighted moving average method.

Calculate the forecasts for 3rd, 4th and 5th months, using exponential smoothing method.

Proof -

Given that,

month           1            2              3              4

sales         5100       5500     5400        5600

F(4) = 0.6 A(3) + 0.3 A(2) + 0.1 A(1)

      = 0.6 [ 5400] + 0.3 [ 5500] + 0.1 [ 5100]

      = 3240 + 1650 + 510

      = 5400

⇒forecasts for the 4th month = 5400

Now,

F(5) = 0.6 A(4) + 0.3 A(3) + 0.1 A(2)

      = 0.6 [ 5600] + 0.3 [ 5400] + 0.1 [ 5500]

      = 3360 + 1620 + 550

      = 5530

⇒forecasts for the 5th month = 5530

Now,

Given that, the exponential smoothing constant α=0.5

Month                   Sales                           Forecast

1                             5100                            5100

2                            5500                           5100 + 0.5(5100 - 5100) = 5100

3                             5400                          5100 + 0.5(5500 - 5100) = 5300

4                             5600                          5300 + 0.5(5400 - 5300) = 5350

5                                                                 5350 + 0.5(5600 - 5350) = 5475

∴ we get

By using Exponential smoothing method -

Forecasts for 3rd month = 5300

Forecast for 4th month = 5350

Forecast for  5th month = 5475

The m’s would all be the same number.Another way of adding the same number to each other would be to multiply that number by the number of times you want to add it to each other.

With m + m + m you are adding it 3 times.

So instead multiply m by 3:

The answer is 3m

Answer:

In the Question the concept used is the algebra

We know that

Answer:

  x ≤ -14

Step-by-step explanation:

We assume you want to solve ...

  x/(-7) +14 ≥ 16

Subtract 14, then multiply by -7.

  x/(-7) ≥ 2 . . . . subtract 14

  x ≤ -14 . . . . . . multiplying by a negative number reverses the inequality

Answer:

The correct answer is m∠2 = 120°

Step-by-step explanation:

There is a triangle rule that states the outer angle of an angle in a triangle is equal to the sum of the remaining two angles in that triangle, which means that m∠2 = 52° + 68° = 120°. This can be proven correct because the sum of two of the angles in the triangle is 120°, which means the final angle is 60°. Since m∠2 is the outer angle of 60°, that means it will be 180° - 60° or 120°.

m<2+= 60

Answer:

The 90% confidence interval for the mean combined fuel economy for Ford Explorers is between 22.95 and 23.63 mpg.

Step-by-step explanation:

We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 16 - 1 = 15

90% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 15 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.9}{2} = 0.95[/tex]. So we have T = 1.7531

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}} = 1.7531\frac{0.78}{\sqrt{16}} = 0.34[/tex]

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 23.29 - 0.34 = 22.95 mpg

The upper end of the interval is the sample mean added to M. So it is 23.29 + 0.34 = 23.63 mpg

The 90% confidence interval for the mean combined fuel economy for Ford Explorers is between 22.95 and 23.63 mpg.

Answer:

  3.6 s

Step-by-step explanation:

This is nicely solved by a graphing calculator. It takes about 3.6 seconds to hit the ground.

__

We notice that the vertical velocity is a multiple of the leading coefficient, so we can solve this by completing the square.

  0 = -4.9(t^2 -2t) +28 . . . . . for h = 0

  28 +4.9 = 4.9(t^2 -2t +1) . . . . . rearrange, add 4.9 to both sides

  32.9/4.9 = (t -1)^2

  1 +(1/7)√329 = t ≈ 3.5912. . . . . square root and add 1

It takes about 3.6 seconds for the watermelon to hit the street.

The sequence is arithmetic because the second differences are constant. Then the correct option is B.

A sequence is a list of elements that have been ordered in a sequential manner, such that members come either before or after.

Consider the given figure, which shows groups of dots arranged in increasingly larger hexagons.

If the pattern continues, the next group of dots would have 61 dots.

The first difference will be

The difference between 7 and 1 is 6.

The difference between 19 and 7 is 12.

The difference between 37 and 19 is 18.

The difference between 61 and 37 is 24.

The second difference will be

The difference between 12 and 6 is 6.

The difference between 18 and 12 is 6.

The difference between 24 and 18 is 6.

Thus, the sequence is arithmetic, because the second differences are constant. Then the correct option is B.

Step-by-step explanation:

x+y=30

x-y=16

2x=14

therefore x=7 and y=23.

the smallest number is 7.

btw jungwoo = best boy

Step-by-step explanation:

Let x be the smallest number

According to the question,

(Let the two numbers be x and y)

x+y=30

= x=30-y

Now,

y-x=16

= y=16+30-y

= 2y=46

= y =23

Also,

x=30-23

= 7

The value of the smallest number is 7

The other number is 23
