Answer:
Slope = 3
Step-by-step explanation:
Slope = (y2-y1)/(x2 - x1)
In this case,
Slope = (-9 + 3) / (-4 + 2)
= -6/-2
= 3
The answer to this question is 492.307
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:
The options are not clearly written but, the volume of square based pyramid is 1/6 the volume of a cube because each of the six faces of the cube will contain one square based pyramid.
Step-by-step explanation:
Let the length of each side of your cube be x
the height of each of the six enclosed pyramids would be x/2. So the volume of each pyramid would be given by:
V = (1/3) × base area × height
V = (1/3) × x^2 × (x/2) = (x^3)/6
Basically it’s like 40x10 and then let’s say your exponent is two so you would do that equation twice so it would be 800
