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.
Okay so she had 67 homework problems and she only finished 25
she has 7 pages to complete and on each page the same number of problems
So we can use subtraction and division
(67 - 25) : 7 =
42 : 7 =
6
So there are 6 problems on each page :)
X squared +14=9x
Square both sides and you get
X+14=3x subtract 14 from both sides
Z
X=3x-14 subtract 3x
-2x=-14 divide negative 2
X=7
Answer:
Step-by-step explanation:
to find the "solution" to this system, set f=g.
then we get:
plugging in 3,-3 for x in both equations, we get:
(3,7),(-3,-7),(-3,-5)
Answer:
is the question asking how long would it take to make enough? if so the answer is 37 hours
Step-by-step explanation:
500 - 150 = 350
350 ÷ 9.50
=36.8421052632
(round up)
=37 hours
