Step-by-step explanation:
Solution:
6 bakers
4 pounds of flour
6 / 4 = 1.5lb.
Answer:
Each Baker Gets 1.5 Pounds Of Flour Each!
Answer: A
Step-by-step explanation: Okay so there are plenty of steps to this equation but to save you time, the answer is A. If your puting
you answer into decimal form it woukd equal x= 4 x= -2.5
Answer:
- D. Y = -0.175x^2 - 3.786x + 121.119
- A. Y= 2x-2
Step-by-step explanation:
1. The data generally goes down to the right, so the peak of the curve will be to the left of the y-axis. That means the x-coefficient will have the same sign as the x^2 coefficient (negative). The values near the y-axis are large positive values, so the y-intercept is positive. The equation with these characteristics is the last one:
... D. Y = -0.175x^2 - 3.786x + 121.119
___
You can have your calculator or spreadsheet program write the regression equation for you. It will give you substantially the same result. (see the attachment)
______
2. For estimating a regression line through data of this sort, it often works well to use the extreme data points: (1.5, 1) and (7.5, 13). If you draw a line through these points, you find that it passes through several other points on the graph, and it has a negative y-intercept. The slope of the line is ...
... (change in y)/(change in x) = (13 -1)/(7.5 -1.5) = 12/6 = 2
Only one of your answer choices has a slope of 2:
... A. Y = 2x-2
2x and 15x are the only like terms
