Determine Upper P (Upper F or Upper G )using the general addition rule. Select the correct choice below and fill in any answer b
Lilit [14]

Answer:

S= {8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 }

event F= {10 , 11 , 12 , 13 , 14}

event G= {14 , 15 , 16 , 17}

a) List of outcomes in F or G

answer;

(F or G) = { 10 , 11, 12 , 13 , 14 , 15 , 16 , 17}

b) P ( F or G) = by counting the number of outcomes in F or G  

Ans ( F or G) = No. of outcomes in ( F or G) / Total no. of outcomes

= 8/12 = 2/3

c) P ( F or G) using general addition rule

Ans P (F or G) = P(F) = P(G) - P( F and G)

      = 5/12 + 4/12 - 1/12

       = (5+4-1)/12 = 8/12 =2/3

Step-by-step explanation:

43. A "Square" cornfield, which means all 4 sides has the same lenght BxH

164.000 ft^2=404.96 NO

156.816 ft^2=396 Yes

174724 ft^2=418 Yes

215908  ft^2=464.66 NO

44. it's the same here, if the area is 81. then each side of the square is 9

1st figure: it has 12 sides x9 =108

2nd figure: it has 10 sides x9=90

3rd figure: has also 12 sides x9=108

45. 13^3= 13x13x13 = 2197

46. 25^2= 25x25 = 625

47.  15^3= 15x15x15 = 3375

48. 34^2= 34x34 = 1156

49.  5 root121= 5 (11)=55

50. -6.root36= - 6 (6)= -36

51.  10 root3 (8) = 10(2) = 20

52. -4. root 144= -4(12) = -48

chubhunter [2.5K]

Answer:

\boxed{\sf \ \ \ f^{-1}(x)=1+\sqrt{x} \ \ \ }

Step-by-step explanation:

the minimum of f is for x = 1 and f(1)=0

f is decreasing for x<=1 and increasing for x>=1

so the domain is [1;+\infty[

f^{-1}(f(x))=x =f^{-1}((x-1)^2)\\\\f(f^{-1}(x))=x=(f^{-1}(x)-1)^2

x>=1 so x is positive and we can take the square root

so f^{-1}(x)=1+\sqrt{x}
