Answer:
A. For every 1 inch of mercury the pressure increases, the boiling point is expected to increase by 1.9°F
Step-by-step explanation:
A regression model is in the form :
y = mx + c
With m being the slope = rate of change
In regression, the value of the slope gives the rate of change in y value per unit increase in the value of x
The slope in the question above is 1.9, this means for every unit increase in mercury pressure, then boiling point, y increases by 1.9°F
The answer is the expression point giving at the right angle of the answe
Answer:
Step-by-step explanation:
6 -Question 13.4
Compute the unit rates.
Tank A:
(5/8 gal) / (1/2 min) = 10/8 gal/min = 5/4 gal/min = 1.25 gal/min
Tank B:
(3/5 gal) / (1/4 min) = 12/5 gal/min = 2.2 gal/min
So tank B is filling faster.
