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
Answer:
So both equations are true
Step-by-step explanation:
#4 was asking you to substitute x = 4 into both equations to see if it's the solution of the equations.
Substitute x = 4
Ritz equation
y = 30x + 20
y = 30(4) + 20
y = 120 + 20
y = 140
Smits equation:
y = 15x + 80
y = 15(4) + 80
y = 60 + 80
y = 140
Both companies charged same price $140 for 4 days
So both equations are true
Answer:
The answer is social value orientation.
Explanation:
Social value orientation is the preference or choice of a person about distributing and allocating resources such as money between himself and another person. It refers to the concern a person has for others and how much weight a person assigns to other people's well being in relation to his own . Social value orientation concept is studied in various scientific disciplines. Here the Dean's social value orientation studies how much he spends for himself and how much money he uses for the department's improvement from the awarded grant.
Answer: Since the y intercept is (0, 4), b = 4 and the slope, m, is given as 2/3.
