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.
Answer:
y = + 5
Step-by-step explanation:
Find the slope of MN, which is
Then, use the formula: y-y₁ = m(x-x₁)
Use point P as (x₁, y₁)
Plugging in x₁ = 6 and y₁ = 1 and simplifying, we find that:
y - 1 = (x - 6)
Simplify to find that:
y = + 4 + 1
y = + 5
Maybe 40 degrees
Please mark as brainliest it correct thank you ;)
Answer:
simplify the expressions
Step-by-step explanation:
you just have to simplify all the different expression and then you can see the ones that are the same
