Answer:
Step-by-step explanation:
The given sequence of numbers is increasing in geometric progression. The consecutive terms differ by a common ratio, r
Common ratio = 6/3 = 12/6 = 2
The formula for determining the nth term of a geometric progression is expressed as
Tn = ar^(n - 1)
Where
a represents the first term of the sequence.
r represents the common ratio.
n represents the number of terms.
From the information given,
a = 3
r = 2
The function, f(n), representing the nth term of the sequence is
f(n) = 3 × 2^(n - 1)
Answer:
-4, 3.
Step-by-step explanation:
x^2 + x - 12 = 0
(x + 4)(x - 3) = 0
x = -4, 3.
Answer: 1.2
Step-by-step explanation:
Given the probability distribution :
Number Sold(x) ____0 ______ 1 _______ 2
Probability p(x) ___0.20 ______0.40 ___ 0.40
The expected number of homes sold :
Expected value (E(x)) = Σ (x * p(x))
= (0 * 0.2) + (1 * 0.4) + (2 * 0.4)
= 0 + 0.4 + 0.8
= 1.2
