Answer: 8.5 years
Step-by-step explanation:
Hi, to answer this question we have to apply an exponential growth function:
A = P (1 + r) t
Where:
p = original population
r = growing rate (decimal form) =18/100 = 0.18
t= years
A = population after t years
Replacing with the values given:
192,000 = 47,000 (1+ 0.18)^t
Solving for t:
192,000/47,000 = 1.18^t
4.08 =1.18^t
ln 4.08 = ln 1.18^t
ln 4.08 =t (ln 1.18)
ln 4.08 / ln 1.18 =t
8.5 years = t

blue marbles
y = yellow marbles
Sum = b+y
The <span>chance of a blue marble being drawn first is:
b / (b+y) = 0.55
</span>The <span>chance of a blue marble being drawn first then a yellow next is:
</span>b / (b+y) * y / (b+y-1) = 0.37
This can be solve easily by using a theorem of Bayes
0.37/0.55 = .67 or 67%
Your answers:
10) (m+7)(m+8) 11) (b-10)(b+2)
12) (k-4)(k+10) 13) (n-9)(n-8)
14) (7r+3)(r-2) 15) (5a+6)(a+2)
Hope it helps
Answer:
(-3/8/-(3/8) then you calculate -3/8*(-3/8) then its going to be - 3/-8*3/8 which equals -3/-3 and that becomes -(-3/3) then that becomes 3/3 and the ANSWER IS 1
Step-by-step explanation: Look at answer above.^^^
