Let y represent the yellow and x the red.
Y= 3x-5 is your equation
1. false because it has only 2 triangular faces
2. true
3. true
4. i think its false, it has four
5.
(a) How would you characterize the relationship between the hours spent on homework and the test scores? Explain
For this case what we see is that we have a scatter diagram, which we can model using a linear trend defining the following variables:
x: number of hours studied.
y: test scores.
The linear relationship would be of the form:
y = mx + b
(b) Paul uses the function y = 8x + 40 to model the situation. What score does the model predict for 3 h of homework?
y = 8x + 40
For three hours of study we have that the note would be approximately:
y = 8 * (3) + 40
y = 64
(c) What does the number 40 in Part (b) mean in the context of the situation?
The number 40 means that if you do not devote any study time, then you expect the test score to be 40.
No I do not think that 12/60 and 16/40 are equivalent because onec you reduce both of the fractions it does not equal.
