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.

Suppose that events a and b are mutually exclusive with p(a) = ½ and p(b) = ⅓.
irina1246 [14]
No, a & b are not independent if they're mutually exclusive.

Mutually exclusive means the two events cannot occur simultaneously. So if "a" happens "b" cannot. In contrast, two events are independent if the occurrence of one has no effect on the occurrence of the other.

Find the side length of a cube with a volume of 166 m
marin [14]
The answer is 5.5 m.


Cube
Volume = length x width x height

Since the length, width and the height are the same in cube, the formula can be:

Volume = length^3


Let x metres be the side length of the cube.

166 = x^3

x = ∛166

x = 5.495864.....

x = 5.5 (nearest tenth)
