Answer:
Predicted values:
Residuals:
Step-by-step explanation:
For this case we assume the following exponential function:
Where x represent the hours and y the predicted values for each hour. We can find the estimated values like this:
Now we can find the residuals with this formula:
And replacing we got:
Answer:
6. P, y=5x
5. P, y=2x
4. N, N
Step-by-step explanation:
If the graph is a straight line that goes through (0, 0), then it represents a proportional relation. The constant in the proportion (k) can be read from the graph as the y-value that corresponds to x=1.

6. P, y = 5x
5. P, y = 2x
4. N, N . . . . The y-intercept is not zero, so this is not a proportional relation.
Answer:
Step-by-step explanation:
Let the sides of the triangle be a, b and c.
<u>We have:</u>
- P = a + b + c = 29
- a = 2b - 5
- c = b + 6
<u>Substitute values and solve for b:</u>
- 2b - 5 + b + b + 6 = 29
- 4b + 1 = 29
- 4b = 28
- b = 7
<u>Find a and c:</u>
- a = 2*7 - 5 = 14 - 5 = 9
- c = 7 + 6 = 13
<u>The sides are:</u> 7, 9, 13
