determine whether the sequence converges or diverges. if it converges, find the limit. if it diverges write none. a_n = e**(8\/\( n 3\))
The required answer is the limit of the sequence is 1.
To determine whether the sequence a_n = e^(8/√(n^3)) converges or diverges, we can use the limit comparison test.
First, note that e^(8/√(n^3)) is always positive for all n.
Next, we will compare a_n to the series b_n = 1/n^(3/4).
To determine whether the sequence converges or diverges, we need to analyze the given sequence a_n = e^(8/(n^3)). The value of (8/(n^3)) approaches 0 (since the denominator increases while the numerator remains constant). 3. Recall that e^0 = 1.
Taking the limit as n approaches infinity of a_n/b_n, we get:
lim (n→∞) a_n/b_n = lim (n→∞) e^(8/√(n^3)) / (1/n^(3/4))
= lim (n→∞) e^(8/√(n^3)) * n^(3/4)
= lim (n→∞) (e^(8/√(n^3)))^(n^(3/4))
= lim (n→∞) (e^((8/n^(3/2)))^n^(3/4))
Using the fact that lim (x→0) (1 + x)^1/x = e, we can rewrite this as:
= lim (n→∞) (1 + 8/n^(3/2))^(n^(3/4))
= e^lim (n→∞) 8(n^(3/4))/n^(3/2)
= e^lim (n→∞) 8/n^(1/4)
= e^0 = 1
Since the limit of a_n/b_n exists and is finite, and since b_n converges by the p-series test, we can conclude that a_n also converges by the limit comparison test.
Therefore, the sequence a_n = e^(8/√(n^3)) converges, and to find the limit we can take the limit as n approaches infinity:
lim (n→∞) a_n = lim (n→∞) e^(8/√(n^3))
= e^lim (n→∞) 8/√(n^3)
= e^0 = 1
as n approaches infinity, the expression e^(8/(n^3)) approaches e^0, which is 1. Conclusion.
So the limit of the sequence is 1.

a certain phone company charges $4.50 for the first five minutes of an international phone call. additional time is charged at $.50 per minute. how much would a customer be charged for an international phone call that started at 9:35 p.m. and ended at 11:15 p.m. the same day?
A customer would be charged $ 52 for an international phone call that started at 9:35 p.m. and ended at 11:15 p.m. the same day.
Charge for first 5 charged = $ 4.50
Charge for additional time = $ 0.50 per minute
Starting time = 9:35 p.m.
End time = 11:15 p.m.
Total minutes = 100 minutes
Total charge = 4.50 + (95 x 0.50)
= 4.50 + 47.50
= 52.00
Hence, a customer would be charged $ 52 for an international phone call that started at 9:35 p.m. and ended at 11:15 p.m. the same day i.e. for 100 minutes.

we fit a piecewise polynomial for a regression, selecting cut-points in our data - how many constraints need to be introduced at each cut-point to obtain a cubic spline? explain each constraint. what would be the total degrees-of-freedom for the curve?
The number of constraints required at each cut-point for a cubic spline is two, and the total degrees-of-freedom for the curve can be calculated using the formula:
degrees-of-freedom = (number of cubic polynomials) x 4 - (number of cut-points) x 2
When fitting a piecewise polynomial for a regression, the number of constraints required at each cut-point to obtain a cubic spline is two. These two constraints are known as continuity constraints. The first continuity constraint is that the two adjacent cubic polynomials must have the same function value at the cut-point. The second continuity constraint is that the two adjacent cubic polynomials must have the same derivative value at the cut-point. These constraints ensure that the cubic spline is smooth and continuous at each cut-point.
The total degrees-of-freedom for the curve can be calculated by subtracting the total number of constraints from the total number of parameters in the model. For a cubic spline, there are four parameters for each cubic polynomial and two constraints at each cut-point. Therefore, the total degrees-of-freedom for the curve can be calculated using the formula:
degrees-of-freedom = (number of cubic polynomials) x 4 - (number of cut-points) x 2
It is important to note that the number of cut-points is equal to the number of pieces minus one, where a piece refers to a continuous interval in the data that is fitted with a single cubic polynomial.

If 3 students make up 10% of the class, how many students are there total in the class?
Answer:
30 students
Step-by-step explanation:
3 students = 10% of the class.
x students = 90% of the class.
(If more, less divides. Let x be the subject. Since we know 10% of the class already, we have to find the remaining 90% that is 100% - 10% = 90%.)
x = 90%/ 10% × 3 students. ( the percentage signs cancel out and so do the zero's.)
x= 9/1 × 3 students ( 9/1 is the same as 9)
x= 27 students
(To find the total, you must add the 10% of the students to the remaining 90% of the students in the class.)
Total number of students in the class = 27 students + 3 students
= 30 students

find the area of the region between y=x1/2 and y=x1/3 for 0≤x≤1.
We have to find the area of the region between y=x^(1/2) and y=x^(1/3) for 0≤x≤1.
To find the area of the region between y=x^(1/2) and y=x^(1/3) for 0≤x≤1, we have to integrate x^(1/2) and x^(1/3) with respect to x. That is, Area = ∫0¹ [x^(1/2) - x^(1/3)] dx= [2/3 x^(3/2) - 3/4 x^(4/3)] from 0 to 1= [2/3 (1)^(3/2) - 3/4 (1)^(4/3)] - [2/3 (0)^(3/2) - 3/4 (0)^(4/3)]= 0.2857 square units

A fair coin is flipped four times. Find: (a) The probability it will land up heads each time. (b) The probability it will land the same way cach time (slightly different from (a)).
Given that a fair coin is flipped four times. We are supposed to find: (a) The probability it will land up heads each time.(b) The probability it will land the same way each time (slightly different from (a)). So, (a) the probability it will land up heads each time is 1/16, (b) the probability it will land the same way each time is 1/8.
(a) The probability it will land up heads each time: The probability of getting a head in a single toss of a fair coin is 1/2. The probability of getting a head four times in a row would be:
P (H) = 1/2, P (H) = 1/2, P (H) = 1/2, P (H) = 1/2
P(4 heads)= 1/2 × 1/2 × 1/2 × 1/2 = 1/16.
So, the probability it will land up heads each time is 1/16.
(b) The probability it will land the same way each time: There are two ways in which all four flips can be the same (all heads or all tails). The probability of getting all heads is:
P(4 heads)= 1/2 × 1/2 × 1/2 × 1/2 = 1/16
The probability of getting all tails is: P(4 tails)= 1/2 × 1/2 × 1/2 × 1/2 = 1/16.
The probability it will land the same way each time is: P(all heads) + P(all tails)= 1/16 + 1/16 = 1/8.
Thus, the probability it will land the same way each time is 1/8.

where do the graphs of the linear equations 10x 12y = 14 and 5x 6y = 7 intersect?
The graphs of the linear equations 10x - 12y = 14 and 5x - 6y = 7 intersect along the entire line represented by the equations.
To find the point of intersection between the graphs of the linear equations 10x - 12y = 14 and 5x - 6y = 7, we can solve the system of equations simultaneously.
First, let's solve the second equation for x:
5x - 6y = 7
5x = 6y + 7
x = (6y + 7) / 5
Next, substitute this expression for x into the first equation:
10x - 12y = 14
10((6y + 7) / 5) - 12y = 14
12y + 14 - 12y = 14
14 = 14
The equation 14 = 14 is always true. This indicates that the two equations represent the same line and are coincident. Therefore, the graphs of the two equations overlap and intersect at all points along the line defined by the equations.
In summary, the graphs of the linear equations 10x - 12y = 14 and 5x - 6y = 7 intersect along the entire line represented by the equations.

In a recent election, 63% of all registered voters participated in voting. In a survey of 275 retired voters, 162 participated in voting. Which is higher, the population proportion who participated or the sample proportion from this survey?
The population proportion who participated in voting (63%) is higher than the sample proportion from this survey (58.91%).
To determine whether the population proportion who participated in voting or the sample proportion from the survey is higher, we need to compare the percentages.
The population proportion who participated in voting is given as 63% of all registered voters.
This means that out of every 100 registered voters, 63 participated in voting.
In the survey of retired voters, 162 out of 275 participants voted. To calculate the sample proportion, we divide the number of retired voters who participated (162) by the total number of retired voters in the sample (275) and multiply by 100 to get a percentage.
Sample proportion = (162 / 275) \(\times\) 100 ≈ 58.91%, .
Comparing the population proportion (63%) with the sample proportion (58.91%), we can see that the population proportion who participated in voting (63%) is higher than the sample proportion from this survey (58.91%).
Therefore, based on the given data, the population proportion who participated in voting is higher than the sample proportion from this survey.
It's important to note that the sample proportion is an estimate based on the surveyed retired voters and may not perfectly represent the entire population of registered voters.
