Determine whether the sequence converges or diverges. If it converges, find the limit. (If an answer does not exist, enter DNE.)
Nata [24]

Answer:

a_{i} = \frac{(-3)^{i}}{4\cdot i!} converges.

Step-by-step explanation:

The convergence analysis of this sequence is done by Ratio Test. That is to say:

r = \frac{a_{n+1}}{a_{n}}, where sequence converges if and only if |r| < 1.

Let be a_{i} = \frac{(-3)^{i}}{4\cdot i!}, the ratio for the expression is:

r =-\frac{3}{n+1}

|r| = \frac{3}{n+1}

Inasmuch n becomes bigger, then r \longrightarrow 0. Hence, a_{i} = \frac{(-3)^{i}}{4\cdot i!} converges.

Meth Barie's ice cream shop wants to decide whether to introduce a new ice cream flavor. They randomly selected 15 customers at
Marianna [84]

Answer:

Meth Barie's ice cream shop should not introduce the new ice cream flavor.

Step-by-step explanation:

We are given the following in the question:  

Population mean, μ = 4.01

Sample mean, \bar{x} = 4.4

Sample size, n = 15

Alpha, α = 0.1

Sample standard deviation, s = 1.6 minutes

First, we design the null and the alternate hypothesis

H_{0}: \mu \leq 4.01\\H_A: \mu > 4.01

We use one-tailed t test to perform this hypothesis.

Formula:

t_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{s}{\sqrt{n}} }

Putting all the values, we have

t_{stat} = \displaystyle\frac{4.4 - 4.0}{\frac{1.6}{\sqrt{15}} } = 0.968

Option B) 0.968

Rejection region:

Now, t_{critical} \text{ at 0.10 level of significance, 9 degree of freedom } = 1.345

So the rejection region would be a value of t-statistic greater than 1.345.

Option B) t > 1.345

Conclusion:

Since,                    

t_{stat} < t_{critical}

We fail to reject the null hypothesis and accept the null hypothesis. Meth Barie's ice cream shop should not introduce the new ice cream flavor.

How do maps use the coordinate plane for locating towns?
Degger [83]

Answer:

Your street name and house number furnish your absolute location. Latitude and longitude provide absolute location for a place on the globe. We can locate places on the globe by determining where lines on latitude and longitude cross.
