So,
Multiply both sides by 11.
Divide both sides by 7.
f = 1
Check.
This checks.
S = {1}
A40=a1 +(40-1)r
in this case r is 3 beceause -2+3 will be 1 etc
a40=-2 +39*3
Given two points: A(x₁,y₁) and B(x₂,y₂), the slope of the line that passes through these points will be:
<span>m=(y₂-y₁)/(x₂-x₁)
We take 2 points of this line:
For example:
(0,3) and (5,3).
We compute the slope:
m=(3-3)/(5-0)=0/5=0
Answer: B) 0</span>
Answer:
a. [0.137, 0.503]
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence interval 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
For this problem, we have that:
A sample of 25 students in the lab, of whom 8 smoke. So 
95% confidence interval
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The correct answer is:
a. [0.137, 0.503]
Answer:
- <u><em>No, if the left-hand limit fo a function approaches infinity because there is a vertical aymptote the limit does not exist.</em></u>
<u><em /></u>
Explanation:
<h2>Important: infinity is not a value!</h2>
When it is said that a limit approaches infinity, it means that the function becomes indefinitely large: as you get closer and closer to the input value, the function becomes larger and larger; in this case, no value can be assigned to the limit, that is, <em>the limit does not exist</em>
For there to be a limit, the function has to approach a specific value. Infinity is not a number; it does not indicate a particular value; again, the limit does not exist.
