In a sample of 1100 U. S.​ adults, 213 think that most celebrities are good role models. Two U. S. Adults are selected from this sample without replacement. Complete parts​ (a) through​ (c).

a) 0.0374  , b)  0.6500  , c) 0.3500

Step-by-step explanation:

Pr (Both consider celebrities role models) = (213/1100) x (212/1099)

= 0.0374

Pr (None consider celebrities role models) = (887/1100) x (886/1099)

= 0.6500

Pr (atleast one consider celebrities role models) = 1 - Pr (None consider role models)

1 - 0.6500 = 0.3500

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
