Answer: 60.5
Step-by-step explanation:
The forecast for the next period using the simple exponential smoothing method is given by:
, where D= actual demand for the recent period, 
smoothing factor, F= forecast for the recent period .
Given: D= 64, 
, F= 59
The forecast for the next period = 
Hence, the forecast for the next period = 60.5
The error interval of the perimeter is 6.1 cm ≤ p < 6.15 cm
<h3>How to determine the error of interval?</h3>
The perimeter is given as:
P = 6.1 cm to 1 decimal place
The smallest number that can be approximated to 6.1 is 6.05, while the largest number is less than 6.15
This means that the interval is:
6.1 cm ≤ p < 6.15

Answer:
B, 25 ft
Step-by-step explanation:
This can be modeled as a triangle. Let x be the height of the flagpole. From the picture, we can see that tan30 = x/43. x = 43tan30 = 25 ft.
Answer:
Well to find the mean of the above
take £ as sigma
therefore,
mean= £fx/£f
This simply means the sum of all the numbers divided by the number of members
therefore,
10 + 11+12+13+14+15+16+17+18= 126
And the number of figure present on the number line are 9, therefore 126 divided by 9
giving you a result of 14
Therefore the mean of the above numbers is 14.
