The least square regression equation for the information provided is y = 9.72x - 40.776

<u>The general equation of a regression model can be expressed thus</u>:

  • y = bx + c

  • Slope, b = r(Sy/Sx)

Calculating slope, b :

  • b = 0.81(177.6 / 14.8) = 9.72

<u>Plugging the values of b, y and x into the equation in other to calculate c</u> :

696 = 9.72(75.8) + c

696 = 736.776 + c

c = 696 - 736.776

c = - 40.776

Therefore, the linear regression model can be expressed as : y = 9.72x - 40.776

borishaifa [10]

<u>Answer:</u>

Approximately 377 cubic inches of water.

<u>Step-by-step explanation:</u>

We know that Mary wants to fill in a cylinder vase and she was told that the vase should be filled 3/4 for the flowers to last the longest. We are to find how much water should she pour into the vase.

So first, we will find the height of the water:

=\frac{3}{4} *10=7.5 inches

Then, find the volume of the water of this height:

Volume = \pi *4^2*7.5 = 376.9

Therefore, Marry should pour approximately 377 cubic inches of water.
