The table shows the growth, in centimeters, of plants in two different soils after two weeks.

which statement explains which soil tended to have a greater growth?

soil a had greater growth because its data have a greater standard deviation.
soil a had greater growth because its data have a greater mean.
soil b had greater growth because its data have a greater interquartile range.
soil b had greater growth because its data have a greater median.

it Might be D. Soil B had greater growth because its data have a greater median.

Step-by-step explanation:

Given is a table about plants growth in soil A and B.

Let us find mean and median.

Soil A

Mean:4.17

Median:3.9

Mode:3.5

Minimum:3.1

Maximum:6

Range:2.9

Count:10

Sum:41.7

Soil B

Mean:4.28

Median:4.25

Mode:3.9

Minimum:2.9

Maximum:5.5

Range:2.6

Count:10

Sum:42.8

Soil B shows a better growth since both mean and median are greater.

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
