The answer is C.
Because only the position is changed for option C. The answer will still be the same.
Answer:
The correct option is B.
Step-by-step explanation:
The number of members of an online community increases each month. It is represented by the function

Where N is the initial number of members and r is the rate of increase.
The initial value for the function is N, because at t=0 the value of M is N. So, option A is incorrect.
The value of M is product of N and
. The second term is free from N, because second term does not contain N. therefore the second factor does not depend on N. So, option B is correct.
It is an exponential growth function, therefore it can not be linear. So, option C is incorrect.
The initial value is constant. In the given function only the value of t can be changed. So, option D is incorrect.
It is c. hope this helps (:
Answer:
= ( 50.66, 57.34)
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean x = 54 ounces
Standard deviation r = 11.7 ounces
Number of samples n = 49
Confidence interval = 95%
z(at 95% confidence) = 2
Substituting the values we have;
54+/-2(11.7/√49)
54+/-2(1.671428571428)
54+/-3.342857142857
54+/-3.34
= ( 50.66, 57.34)
Therefore, the 95% confidence interval (a,b)
= ( 50.66, 57.34)
