Answer:

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.

Three numbers are in the ratio of 2:3:4 and their LCM are 240. Their HCF is?<br>

Dmitrij [34]

Answer:

20.

Step-by-step explanation:

Assign variables. The numbers acan be 2x, 3x and 4x. Then, LCM of 2x, 3x and 4x is 12x

12x = 240

(240/12) = x = 20

The HCF of 2x, 3x, and 4x is 20. (Because x is the highest common factor.)

If f(x)=1/6x+12, then f^-1(x)=<br> PLEASE HELP

Finger [1]

$f(x)=\dfrac{1}{6}x+12\to y=\dfrac{1}{6}x+12$

Change x to y, and y to x.

$x=\dfrac{1}{6}y+12$

solve for y:

$\dfrac{1}{6}y+12=x\ \ \ |-12\\\\\dfrac{1}{6}y=x-12\ \ \ \ |\cdot6\\\\y=6x-72$

Your answer is:

$f^{-1}(x)=6x-72$
