Answer:

a. the line that passes through the most data points.

Step-by-step explanation:

Regression analysis, is used to draw the line of‘ best fit’ through co-ordinates on a graph. The techniques used enable a mathematical equation of the straight line form y=mx+c to be deduced for a given set of co-ordinate values, the line being such that the sum of the deviations of the co-ordinate values from the line is a minimum, i.e.

erica [24]

Answer:

Water is stored in the following places: The lithosphere (the solid outer crust and upper mantle). In oceanic crust it is stored within the rock structure which it is composed of and in continental crust it is also found in rocks, minerals, and also in clay and as groundwater.

I say the lithosphere.

Step-by-step explanation:

or it can be

But new research suggests a different origin for the oceans: they simply seeped out of the center of the Earth. The finding, published in Science, suggests that a reservoir of water is hidden in the Earth's mantle, more than 400 miles below the surface.

The top band in the state charges C(x)=55x+15,000, where x is the total number of attendees at the concert. The venue charges $7
suter [353]

The venue will break even after selling 1000 tickets.

The value will be $70,000 at that point.

Step-by-step explanation:

Given,

Charges of band;

C(x) = 55x+15000

Per ticket charges by Venue = $70

V(x) = 70x

For breaking even,

C(x) = V(x)

55x+15000=70x\\15000=70x-55x\\15000=15x\\15x=15000

Dividing both sides by 15

\frac{15x}{15}=\frac{15000}{15}\\x=1000

The venue will break even after selling 1000 tickets.

Putting 1000 in V(x)

V(1000)=70(1000)\\V(1000)=70000

The value will be $70,000 at that point.

A school ordered 3 large boxes if board markers. After giving 15 markers to each of 3 teachers, there were 90 markers left. How
Elis [28]

Answer:

45 markers were in each box.

Step-by-step explanation:

To solve the problem, the total number of markers must be calculated and then divided by the number of original large boxes.

The number of markers is calculated as follows:

90 left over, 15 for each teacher and there are three teachers, that is, 15 * 3 = 45

That is: 90 + 45 = 135 markers in total.

Therefore per box would be 135/3 = 45 markers were in each box.
