Answer:
The value of 2 in the first digit is 100,000 times greater than the value of 2 in the second digit
Step-by-step explanation:
Firstly, we need to know the value of the 2 in 234,567 and that is 200,000
The value of the 2 in 765,432 is simply 2
So the number of times the value of the first 2 is greater than the value of the second 2 is;
200,000/2 = 100,000
So the value of 2 in the first digit is 100,000 times greater than the value of 2 in the second digit
Answer: 16590
Step-by-step explanation:
The formula we use to find the sample size is given by :-
, where p = prior estimate of population proportion.
= Critical z-value (Two- tailed)
E= Margin of error .
Let p be the population proportion of cyanobacteria.
Given : E = 0.01
Critical value for 99% confidence interval : 
If Ian does not want to rely on previous knowledge , then we assume p=0.5 because the largest standard error is at p=0.5.
Now, the required sample size = 

Required sample size = 16590
Step-by-step explanation:
Since 8.7b = (-2.9) * (-3b),
and -11.6 = (-2.9) * (4),
8.7b - 11.6 = -2.9(4 - 3b).
