Consider the following time series data.
Month 1 2 3 4 5 6 7
Value 24 13 20 12 19 23 15
a. Construct a time series plot. What type of pattern exists in the data?
b. Develop the three-week moving average forecasts for this time series. Compute MSE and a forecast for week 8.

a is 8.b is 10.c is 10.5. d is -.5

step-by-step explanation:

just minus the smallest number from the biggest.

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough

good luck on ur quiz test or homework. have a good day : )
