A structure with a design life of 50 yr is planned for a site where high- intensity earthquakes may occur with a return period of 100yr. The struc- ture is designed to have a 0.99 probability of not su ering damage within its design life. Damage effects between earthquakes are statistically independent. If occurrence of high intensity earthquake at the site is modeled by Bernoulli sequence what is the probability of damage to the structure under a single earthquake?

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

b. hoped i'm right lol

step-by-step explanation:

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).

answer: idk wbu

step-by-step explanation: umm..
