Answer:
The slope of the regression line is 0.0138
Step-by-step explanation:
The problem tells us that there is a linear relationship between the dive duration and the depth.
Linear equations have the form y = mx + b where m is the slope, y is the dependent variable and x is the independent variable.
In this problem we have that the depth is the independent variable, the dive duration is the dependent variable and the regression equation is DD = 2.69 + 0.0138D where DD is the dive duration and D is the depth. From the previous paragraph, we can observe that the slope is the coefficient of the dependent variable. Therefore, for this equation the slope is 0.0138.
I could be wrong, but it seems that there are only 2 possible squares in this grid.
•One square has a side length of 2, meaning that the area is 2x2 which is 4 units squared (can be written as 4 units^2)
•The other square has side lengths of 1. 1x1=1 unit^2.
We know that
[volume of cylinder]=pi*r²*h------------> h=[volume of cylinder]/(pi*r²)
Volume=5652 cm³
r=7.5 cm
so
h=[5652]/(3.14*7.5²)-----------> h=32 cm
<span>the height of the soap in the full dispenser is 32 cm
</span><span>the height when 4,239 cubic centimeters of soap remains in the dispenser is
</span>h=[4239]/(3.14*7.5²)-----------> h=24 cm
hence
<span>the difference is 32-24--------> 8 cm
</span>
the answer is
8 cm
