B is 2 out of 12
c is if you were talking probability then you would have put down one out of 6 because there is one 3 out of 6 sides but i believe i would expect to see two times 34 because it is two time the dice and it gives you the capability to earn three twice as much so you should see it at least 68 times
HOPE THIS HELPS
im not clear on a tho
Answer:
x = 5
Step-by-step explanation:
Given
x =
( square both sides )
x² = 3x + 10 ( subtract 3x + 10 from both sides )
x² - 3x - 10 = 0 ← in standard form
(x - 5)(x + 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 5 = 0 ⇒ x = 5
x + 2 = 0 ⇒ x = - 2
As a check
Substitute these values into the equation and if both sides are equal then they are solutions.
x = 5
right side =
=
= 5 = left side ← solution
x = - 2
right side =
=
= 2 ≠ - 2 ← not a solution
Thus x = 5 is the solution to the equation
Answer:
Step-by-step explanation:
a ) The worth of Jean-Claude's gnome after 1 year
= 80000 x 1.02
= £81600
b ) common ratio of geometric progression
= 81600 / 80000
= 1.02
c ) worth after 10 years
= 80000 x 1.02¹⁰
= 80000 x 1.21899
= £97519.55
d )
120000 = 80000 x
1.5 = 
ln1.5 = k ln 1.02
k = ln 1.5 / ln 1.02
= .4054 / .0198
= 20.47 years .
