18% of 40 is 7.2

Change the percentage (18%) into a decimal by dividing it over 100:

18/100 = 0.18

Divide 7.2 by the decimal (0.18):

7.2 / 0.18 = 40

zhuklara [117]

The minimum thickness of the book would simply be the sum of the thickness of the two cover pages and all the pages in between. That is:

minimum thickness = 0.9 mm * 2 + 0.13 mm * 400

The population of lengths of aluminum-coated steel sheets is normally distributed with a mean of 30.0 inches and a standard devi
alexira [117]

Answer: 0.8490

Step-by-step explanation:

Given :  The population of lengths of aluminum-coated steel sheets is normally distributed with a mean of 30.0 inches and a standard deviation of 0.9 inches.

i.e. \mu=30 and \sigma=0.9

Let x denotes the lengths of aluminum-coated steel sheets.

Required Formula : z=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}

For n= 36 , the probability that the average length of a sheet is between 29.82 and 30.27 inches long will be :-

P(29.82

∴ Required probability = 0.8490

Which of the following polynomial functions is graphed below?
Olegator [25]

Answer: B. f(x)=(x+4)(x-2)^2(x+3)

Step-by-step explanation:

in the graph there's two negative x value and one positive x value

so the function should be in a form of f(x)= (x+a) (x-b)^2 (x+c)

the one with negative value has a square, (x-b)^{2}, because that's where the y = 0 (the point is hitting the (x,0))
