Answer:
The relationship is positive.
The model predicts a score of 60.
Not sure what part b is.
Step-by-step explanation:
Since while the money spent on advertising increases while the items sold increases, we have a positive relation between both variables.
By looking at where 30 is on the graph, we can see it lines up with 60,the middle between $40 and $80 on the y axis and so we know this is the cost associated with this value.
Sqrt(50) = sqrt(25*2) = sqrt(25) * sqrt(2) = 5*sqrt 2, answer is A
Alright, lets get started.
For making complete square, we will add and subtract 49 in this
Comparing the standard equation of parabola
where (h,k) are vertex
So, comparing the equation with standard one, h, k would be = (-7 , -89)
So, the vertex are (-7 , -89) : Answer
Hope it will help :)
45cm I’m sorry that’s not the answer I just need answers for my questions sis
