Answer:

The exponential smoothing forecast for period 13 = 39.68

Step-by-step explanation:

As given,

\alpha = 0.4

Time                 Sales                              forcast

1                            48                                  

2                           41                                 48

3                           37                                 48 + \alpha {(41 - 48)} = 45.2

4                           32                                 45.2 + \alpha {(37 - 45.2)} = 41.92

5                           36                                 41.92 + \alpha {(32 - 41.92)} = 37.95

6                           31                                 37.95 + \alpha {(36 - 37.95)} = 37.17

7                            43                                 37.17 + \alpha {(31 - 37.17)} =  34.70

8                           52                                 34.70 + \alpha {(43 - 34.70)} = 38.02

9                           60                                 38.02 + \alpha {(52 - 38.02)} = 43.61

10                          48                                 43.61 + \alpha {(60 - 43.61)} = 50.17

11                           41.9                                 50.17 + \alpha {(48 - 50.17)} = 49.30

12                           29.7                                 49.30 + \alpha {(41.9 - 49.30)} = 46.34

13                                                                    46.34 + \alpha {(29.7 - 46.34)} = 39.68

∴ we get

The exponential smoothing forecast for period 13 = 39.68

Express the confidence interval (0.036, 0.086) in the form of p-e< p
lina2011 [118]

Answer:

p-e< p < p+e

(0.061 - 0.025) < 0.061 < (0.061 + 0.025)

0.036 < 0.061 < 0.086

Step-by-step explanation:

Given;

Confidence interval CI = (a,b) = (0.036, 0.086)

Lower bound a = 0.036

Upper bound b = 0.086

To express in the form;

p-e< p < p+e

Where;

p = mean Proportion

and

e = margin of error

The mean p =( lower bound + higher bound)/2

p = (a+b)/2

Substituting the values;

p = (0.036+0.086)/2

Mean Proportion p = 0.061

The margin of error e = (b-a)/2

Substituting the given values;

e = (0.086-0.036)/2

e = 0.025

Re-writing in the stated form, with p = 0.061 and e = 0.025

p-e< p < p+e

(0.061 - 0.025) < 0.061 < (0.061 + 0.025)

0.036 < 0.061 < 0.086

Carol is sixty inches tall. This is twenty inches less than two times mindys height. How tall is mindy?
deff fn [24]

Alright lets break it down:

Carol = 60 inches tall

Mindy = ??

Lets turn words into numbers:

60 inches is 20 inches less than (2x) Mindy's height

60 inches + 20 inches = 80 inches

This helps us visualize it better, if 60 is 20 inches less than two times Mindy's height, then that means 80 is two times Mindy's height, right?

80 ÷ 2 = 40 inches

Mindy's height is 40 inches

If this is still unclear, comment back.

Hope I was of use, best of luck.

Lauryn’s wages were not as much as she had budgeted. How can her budget be modified so there will be a positive actual net incom
shutvik [7]

The <em><u>correct answer</u></em> is:

Her variable expenses can be reduced.

Explanation:

In a household budget, you have fixed expenses and variable expenses.

Fixed expenses are expenses that are the same from month to month, such as a car payment, rent, power bill, etc. These cannot be reduced; if you were to pay less on your car payment, your car would be repossessed; paying less than you owe on the power bill can result in your power being disconnected; etc.

Variable expenses are expenses that are different from month to month, such as food, clothing, shopping, etc. If you are dealing with a situation where your wages are less than you anticipate, you can reduce items within your variable expenses to make sure you have enough money. For example, you can purchase fewer clothes that pay period or cut your grocery bill down.
