Answer:
xy ≈ 2.3
Step-by-step explanation:
Logarithms can be used to find x and y.
3^x = 4
x·log(3) = log(4)
x = log(4)/log(3)
__
4^y = 12
y = log(12)/log(4)
__
Then xy is ...
xy = log(4)/log(3) × log(12)/log(4) = log(12)/log(3)
xy ≈ 1.079/0.477
xy ≈ 2.26
Lets analyse, the sequence adds 20 to the previous term, so that is:
f(n + 1) = 20 + f(n)
where f(1) = 110
Answer:
r(x) = 14x - 18
Step-by-step explanation:
(p×2)(x) = 2×p(x) = 2×(7x - 9) = 14x - 18
Answer:
.28 = P( not winning)
Step-by-step explanation:
The probability of winning is .72
The 2 possibilitites are winning and not winning. They must total 1
1 = P(winning) +P( not winning)
1 = .72 + P( not winning)
Subtract .72 from each side
1-.72 = P( not winning)
.28 = P( not winning)
