Answer:
2.2%
Step-by-step explanation:
Given the following :
Population in year 2000 (A) = 4.2 million
Expected population every 32 years = 2 *A
The growth rate per year =?
The population figure after 32 years = (2 * 4.2 million) = 8.4 million
Using the exponential growth formula :
P(t) = A × (1 + r)^t
(1 + r) = g = Total growth percent
A = Initial population
t = time
P(t) = 8.4 million
8,400,000 = 4,200,000 × g^32
g^32 = (8400000/4200000)
g^32 = 2
Taking the root of 32 on both sides
g = 1.02189714865
g = (1 + r)
1.02189714865 = 1 + r
r = 1.02189714865 - 1
r = 0.02189714865
.rate = 0.02189714865 * 100
= 2.18971486541%
= 2.2% ( nearest tenth)

i converted them to decimal
-70% = -0.70
Explanation: Every time you need to change percentage to decimal, move the decimal 2 times to the left.
0.34 = 0.34
Explanation: It stays the same because it is already in decimal form.
-2/5 = -0.40
Explanation: you divide with a calculator -2 divided by 5 and that is- 0.40 or you can change the denominator to 100 which you multiply the numerator and denominator by 20: 5*20=100 and -2*20=40 then -40/100 is -0.40
0.96% = 0.0096
Explanation: Every time you need to change percentage to decimal, move the decimal 2 times to the left.
-0.70, 0.34, -0.40, 0.0096
least to greatest:
-0.70, -0.40, 0.0096. 0.34
