Answer:

x = -1/10 or -0.1

Step-by-step explanation:

-1.8 - 6x = 6(0.1 + 3x)

-1.8 - 6x = 0.6 + 18x

-6x - 18x = 0.6 + 1.8

-24x = 2.4

-x = 2.4/24

-x = 24/10 / 24

-x = 24/10 * 1/24

-x = 24/240

-x = 1/10

x = -0.1

Answer:

-0.13

Step-by-step explanation:

-1.8 - 6x = 6(0.1 + 3x)

Expand the bracket

-1.8 - 6x = 6x0.1 + 6 x 2x

-1.8 -6x = 0.6 + 12x

Collect like terms

-1.8 -0.6 = 6x + 12x

-2.4 = 18x

Divide both sides by 18

-2.4/18 = 18x/18

x = -0.13

The height of a sunflower is normally distributed with a mean of 14.2 feet and a standard deviation of 2.15. What is the probabi
tekilochka [14]

Answer:

0.153

Step-by-step explanation:

Chjmk

In this question, we are asked to calculate the probability of selecting a sunflower greater than a particular height.

What to do in this case is to first find the z-score based on this information given.

Mathematically,

Z-score = x- mean/standard deviation

Here, z-score will have a value of;

(16.4-14.2)/2.15 = 1.023

Therefore,

P(height >16.4ft) = P(Zscore >1.023) = 1-Fz(1.023) = 0.153
