Answer:
No
Step-by-step explanation:
N = 10,000
n= 800
p = .28
Sampling distribution drawn from specific population. So it is not safe to assume that sampling proportion of customers is approximately normal.
Answer:
<em>It will take 26.34 minutes for the population to reach 5 times its initial value</em>
Step-by-step explanation:
<u>Exponential Growing</u>
The population of bacteria grows at a rate expressed by the equation:

Where t is in minutes.
We need to know when the population will reach 5 times its initial value. The initial value can be determined by setting t=0:

Now we find the time when the population is 5*256=1,280. The equation to solve is:

Dividing by 256:

Taking natural logarithms:

Applying the logarithm properties:

Solving for t:

It will take 26.34 minutes for the population to reach 5 times its initial value
Answer:
t > 8
Step-by-step explanation:
Given that :
Initial volume = 16 litres
Addition rate = 4 litres per minute
Target volume > 48 litres
Let number of minute for which water is added to achieve these = t
Mathematically,
Initial volume + (addition rate * t) > target volume
16 + 4t > 48
Collect like terms
4t > 48 - 16
4t > 32
Divide both sides by 4
4t/4 > 32/4
t > 8
Laura will need add water at 4 Litre per minute rate for more than 8 minutes
