Answer and explanation:
Given : The demand for a product for the last six years has been 15, 15, 17, 18, 20, and 19. The manager wants to predict the demand for this time series using the following simple linear trend equation : 
To find : What are the forecast errors for the 5th and 6th years?
Solution :
Data : 15, 15, 17, 18, 20, and 19.
The simple linear trend equation is given as, 
For t = 5 years



Observed 
Predicted 
Forecast error = Observed – Predicted = 20 – 22 = -2
Absolute forecast error = |-2| = 2
.
For t = 6 years



Observed 
Predicted 
Forecast error = Observed – Predicted = 19 – 24 = -5
Absolute forecast error = |-5| = 5.

Answer:
Euclid introduced the axiomatic
Step-by-step explanation:
<h2>Answer:</h2>
<u>Cost of basketball sneakers with tax</u> = $96.12
<u>Amount of tax</u> = 8% of cost price
= 8/100 × 96.12
= $7.6896.
<u>Cost of sneakers without tax</u> = $96.12 - $7.6896.
= $88.43.
A polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables. imports of coffee into a country during this years 1997 is 1.344
<h3>What is a polynomial?</h3>
a polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables.
P(x)=0.7166x²+6.267x+1.344
when x = 0, it represents 1997
Substitute the value of x as zero in polynomial.
P(0)=0.7166(0)²+6.267(0)+1.344
P(0)=0+0+1.344
P(0)=1.344
The amount of coffee imported in the year 1997 was approximately 1.344 pounds.
Hence amount of coffee imported in the year 1997 was approximately 1.344 pounds.
