Answer:
It will take 5 years for the population to reach 1,944. Option D is correct.
Step-by-step explanation:
Initial population = I = 8
Final population = F = 1944
number of years = x
As given, the population is tripled every year that can be calculated using:
F = I*3^x
By putting values in this equation, we get
1944 = 8*3^x
1944/8 = 3^x
243 = 3^x
3^x = 243
3^x = 3^5
x = 5 bases are same so powers can be simplified.
Therefore, it will take 5 years for the population to reach 1,944. Option D is correct.

Answer:
The given z-score of 188cm is 1.95 which means that this value is 1.95 standard deviations above mean ..
Step-by-step explanation:
First, we have to define z-score:
z-score tells us that how many SDs a value is above or below mean.
If the z-score is positive then the value is above mean and if the z-score is negative then the value is below mean.
The given z-score of 188cm is 1.95 which means that this value is 1.95 standard deviations above mean ..
