A normal distribution is a fundamental tool in statistics which ends up being applied to nearly all elds where mathematics is used. The equation for the "probability density function" is a function that tells how the probability is distributed for di erent values of x. Areas under the normal distribution give the probabilities of landing at x value in the width of the region given, and so the area underneath the entire function (from 1 to 1) is 1. The equation for a particular normal distribution is N(x) = r 2 e(x2)2 Find the center of mass on the x-axis of the region de ned as the region bounded by x = a, x = b, N(x), and the x-axis if you know that the regions area is A. (This should be in terms of a, b, and A)

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius

: )

inch

step-by-step explanation:

yard and mile are too big.

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
