The number of bacterial population after 5 hours is; 816
- The formula for the exponential growth of the population is;
N(t) = N_o(1 + r)^(t)
Where;
N(t) is number of bacteria after t hours
N_o is number of bacteria initially
r is growth rate
t is time
N_o = 480
r = 11.2% = 0.112
t = 5
N(5) = 480(1 + 0.112)^(5)
N(5) = 816.14
- Approximating to a whole number gives; N(5) = 816 bacteria

Answer:
7
Step-by-step explanation:
When the mean of two numbers is the same as one of the numbers, then the other number also has that same value. This is true for any kind of mean:
arithmetic, geometric, harmonic.
The other number would be 7.
__
The geometric mean (m) of a and b is ...
m = √(ab)
We have ...
7 = √(7b)
49 = 7b . . . . . square both sides
7 = b . . . . . . . .divide by 7
a = b = m = 7 in this case.
p = Probability of picking a shoe of size less than 7.5
x = number of shoes that are less than size 7.5
n = number of shoes total
In this case, x = 6 and n = 15, so
p = x/n = 6/15 = 2/5 = 0.400
Answer: Choice D) 0.400
