Answer:
144, 36, 9, 2 
Step-by-step explanation:
The recursive formula allows us to find a term in a sequence from the previous term.
Given
= 
Given the fourth term we require to work back to the third term , second and so on. Rearrange the formula to give
Multiply both sides by 4, then
= 4
Given a₄ = 2
, then
a₃ = 4 × a₄ = 4 × 2
= 9
a₂ = 4 × a₃ = 4 × 9 = 36
a₁ = 4 × a₂ = 4 × 36 = 144
Answer:
d. is the sum of the probabilities of the sample points in the event.
Step-by-step explanation:
Suppose we have a fair coin then the the sample space S is given by {(H), (T)}
the head and tail are the sample points.
the probability of sample space will be given by the sum of probability of head and tail. P(S)= P(A) + P(B)
1= 1/2+ 1/2
The total probability of the sample space always equals 1
The individual probabilities add up to to give the probability of the sample space.
Remember, you can do anything to an equation as long as you do it to both sides
and when multiply or divide by a negative in inequalities, flip the direction of the sign
12x-39<9
add 39 to both sides
12x<48
divde bothh sides by 12
x<4
-4x+3<-6
minus 3 both sides
-4x<-9
times both sides by -1 and flip sign
4x>9
divide both sides by 4
x>9/4
