Answer:
C. 4
Step-by-step explanation:
All other answer choices involve the variable 'b' and/or are tied to it in some way. The sole number 4 has no connection to the variable b, therefore it is C. 4.
Answer:
Option c.
Step-by-step explanation:
Using the normal curve to approximate a sampling distribution:
For a sample size n and a proportion n, the normal curve can be used if:
and 
Option a:
So option a cannot be used.
Option b:
So option b cannot be used.
Option c:
So option c can be used, and is the answer
Option d:
So option d cannot be used.

Answer:
Step-by-step explanation:
A number is at least 65. It means the number n can be 65 or greater.
<u>Its translation is:</u>
<em>The answer options don't have this included.</em>
The formula of geometric sequence is expressed in the following manner:
an = a1 * r^(n-1) where r is the ratio and n is an integer.
Substituting, to find r
358.80 = <span>14 * r^(8)
r is equal to 1.5
hence,
</span><span>a19 = 14* 1.5^(19-1)
</span>a19 <span> ≈ 20,690.</span>
