Answer:
The correct option is C) $145,000
Step-by-step explanation:
Consider the provided regression.
sales y in $1000 and advertising x in $100
We have given that they spent $900 in advertising.
That means substitute x=9 in above regression because x is in $100.
It is given that y in $1000.
That means the total sale is 145×$1000=$145000.
Hence, the correct option is C) $145,000
Answer:
D
Step-by-step explanation:
yes it is.
start by multiply by 4 to get rid of the fraction on x
4 () = 4(4) + 4()
x = 16 + 8y/3
Then by 3 to get rid of that one
3(x) = 3(16) + 3()
3x = 48 + 8y
Then subtract 8y from both sides to get
3x - 8y = 48
Product of odd number of negative terms is negative.
Hence, I have given all the 8 possibilities.
