Answer:

The correct option is C.

Step-by-step explanation:

The general form of linear regression equation is

y=a+bx           .... (1)

where,

b=\frac{\sum_{i=1}^nx_iy_i-n\overline{x}\overline{y}}{\sum_{i=1}^nx_i^2-n\overline{x}^2}

a=\overline{y}-b\overline{x}

Using the graphing calculator, we get

a=0.0142857

b=2.01071

Substitute the values of a and b in equation (1).

y=0.0142857+2.01071x

The equation of line of best fit is y=0.0142857+2.01071x, where x is number of years and y is height of trees.

Substitute x=22 to find the height of trees after 22 years.

y=0.0142857+2.01071(22)

y=44.2499057

y=44.25

The height of trees after 22 years is 44.25 ft. Therefore the correct option is C.

Which graph below represents a functional relationship? A. 10 10 8 8 6 6 4 2 2 X 10864 6 8 10 10 8 6 4 4 6 8 10 -21 4 -61 -8 -8

Answer:

Graph (C)

Step-by-step explanation:

To find whether the graph\table represents a relationship or a function we have to analyze the input-output values given.

Graph A.

In this graph for every input value (x-value) there are two output values (y-values).

For x = -2, y = -2, 2

So the graph doesn't represent a function.

Graph B.

For every x value there are two y-values

For x = -5, y = -3, 3

So the graph doesn't represent a function.

Graph C.

For every input value there is a different y-value.

Therefore, graph represents a function.

Graph D.

In this graph for x = 3, y = 1, 2, 3, 4

For one value of x, there are four values of y.

Therefore, graph doesn't show the relationship.
