Ratio test is one of that is used to determine the convergence or divergence of infinite series. It states that [tex]L = \lim_{n→∞} |\frac{ a_{n+1} }{a_n}| \\ [/tex]

We have a series, [tex] \sum_{n= 1}^{\infty}a_n \\ [/tex], where [tex]a_n = \frac{ ( 6n + 7)8^{n+4} }{11^n}[/tex]. We have to check the convergence of above series with the help of ratio test. Here, [tex]a_n = \frac{ (6n + 7)8^{n+4} }{11^n}[/tex].

[tex]a_{n+1} = \frac{(6(n+1)+ 7)8^{n + 1+4 }}{11^{n+1}}[/tex]

[tex]= \frac{(6n+ 13)8^{n + 5}}{11^{n+1}}[/tex].

Now, [tex]L = \lim_{n→∞} |\frac{ a_{n+1} }{a_n}| \\ [/tex]

[tex] = \lim_{n→∞} |\frac{\frac{(6n+ 13)8^{n + 5}}{11^{n+1}}}{\frac{(6n +7 )8^{n +4 }}{11^{n}}}|\\ [/tex]

[tex] = \lim_{n→∞} |\frac{(6n+ 13)8^{n + 5}}{11^{n+1}}×\frac{11^{n}}{(6n +7 )8^{n +4 }}|\\ [/tex]

[tex] = \frac{8}{11}\lim_{n→∞} |\frac{6n+ 13}{6n+7 }|\\ [/tex]

[tex] = \frac{8}{11}\lim_{n→∞} |\frac{n(6+ \frac{ 13}{n})}{n(6 +\frac{7}{n} )}|\\ [/tex]

[tex] = \frac{8}{11} = 0.72 [/tex] < 1

Answer: $1,100 per month for 10 years, if the account earns 2% per year

Step-by-step explanation: $1,100 per month for 10 years, if the account earns 2% per year What the student or parent is asking is: If they deposit $1,100 per month in a savings/investment account every month for 10 years, and they earn 2% per year, how much will the account be worth after 10 years? Deposits are monthly. But interest crediting is annual. What we want is to match the two based on interest crediting time, which is annual or yearly. 1100 per month. * 12 months in a year = 13,200 per year in deposit Since we matched interest crediting period with deposits, we now want to know: If they deposit $13,200 per year in a savings/investment account every year for 10 years, and they earn 2% per year, how much will the account be worth after 10 years? This is an annuity, which is a constant stream of payments with interest crediting at a certain period.

Step-by-step explanation:

Nice that the numbers are in order for you

The min is your smallest number = 28

To find the next part separate into 4 equal parts so you have 3 lines

The first line is between 34 and 34 the average of the 2 numbers is your lower quartile

lower quartile =34

Step-by-step explanation:

The actual average time spent playing outdoors by 10-year-old American children could be 2.67 minutes higher or lower than the reported range of 20.02 to 25.36 minutes.

The margin of error in the report stating that a 10-year-old American child spends an average of 20.02 to 25.36 minutes playing outdoors per day can be calculated by subtracting the lower value from the higher value and dividing by 2. In this case, the margin of error is :

To find the margin of error, we need to calculate the halfway point between these two values.
(25.36 - 20.02) / 2 = 2.67

Therefore, the margin of error is approximately 2.67 minutes. This means that the actual average time spent playing outdoors by 10-year-old American children could be 2.67 minutes higher or lower than the reported range of 20.02 to 25.36 minutes.

Thus, the actual average time spent playing outdoors by 10-year-old American children could be 2.67 minutes higher or lower than the reported range of 20.02 to 25.36 minutes.

Answer:

Total deposit: $501.6

Total Balance: $985.05

Step-by-step explanation:

Aisha's original total is 523.45. Since she is depositing a check for $435.62 and a check for 65.98, you add both check totals to the original balance, by lining up the numbers and adding down the line. This will be the total deposit:

435.62

+ 65.98

    =

$501.6

$501.6 is the total deposit. To find the total checking balance, add the total deposit to $523.45.

523.45

+501.6

    =

1025.05

This is her total balance before Aisha receives $40.

Next, you subtract what she wants to deposit, $40, since she is taking $40 out of her checking account.

1025.05

- 40.00

   =

985.05

The total checking balance is $985.05

The three intervals do you have the most confidence that the interval captures the population mean (x) is (2.4, 4.5). option (b).

An interval is a range of values that is used to estimate a population parameter, such as the mean.

To answer your question, let's look at the three intervals you provided: (1) (1.3, 4), (2) (2.5, 4.5), and (3) (2, 5). We want to determine which interval has the highest level of confidence in capturing the population mean.

Interval (1) has a range of 2.7 units, which is relatively large. This means that it is possible that the true population mean could fall anywhere within this range.

Interval (2) has a smaller range of 2 units, which means that it is more likely to capture the true population mean. Interval (3) has the largest range of 3 units, which makes it less likely to capture the true population mean compared to interval (2).

Hence the correct option is (b).

Step-by-step explanation:

Let's call the length of the base of the triangle "b". We know that the height of the triangle is double the length of the base, so the height can be written as "2b".

We also know that the area of the triangle is approximately 200 square feet. The formula for the area of a triangle is:

A = (1/2)bh

where A is the area, b is the length of the base, and h is the height.

We can substitute in the values we know:

200 = (1/2)bh

Since we know that h = 2b, we can substitute that in:

200 = (1/2)b(2b)

Simplifying:

200 = b^2

This is the equation we can use to find the length of the sign's base, b.

We can set the equation to: 200 = (1/2) × b × (2b)

To find the length of the sign's base, b, we can use the equation for the area of an isosceles triangle: A = (1/2)bh, where b is the length of the base and h is the height. Since we know that the height is double the length of the base, we can substitute 2b for h in the equation: A = (1/2)b(2b). Simplifying, we get A = b^2. Since we know that the area should be approximately 200 square feet, we can set A = 200 and solve for b: b^2 = 200. Taking the square root of both sides, we get b = 14.14 feet. Therefore, the length of the sign's base should be approximately 14.14 feet.

To find the equation for the length of the base of the sign, we'll use the formula for the area of a triangle, which is:

Area = (1/2) × base × height

Since the height of the triangle is double the length of its base (h = 2b), we can rewrite the equation as:

Area = (1/2) × b × (2b)

The owner of Trixie's Sweets and Treats wants the area of the sign to be approximately 200 square feet. So, we can set the equation to:

200 = (1/2) × b × (2b)

Now we have the equation that you can use to find the length of the sign's base, b.

If the population standard deviation of a sample increases without other changes, the confidence interval is most likely to widen.

This is because the standard deviation is a measure of the spread of the data, so if it increases, the data points are more spread out from the mean. As a result, the range of values that could reasonably contain the true population parameter (i.e., the confidence interval) needs to be wider to account for the increased variability in the sample.
If the population standard deviation of a sample increases without other changes, the confidence interval is most likely to become wider.
When standard deviation increases, it indicates more variability in the data. As a result, the confidence interval, which is a range of values that estimates the true population parameter with a certain level of confidence, needs to be wider to account for the increased variability. This ensures that the true population parameter is still captured within the interval with the same level of confidence.

The weight of the remaining paper is 5/12 pounds.

A ream of printer paper is a standard measure of paper quantity that typically consists of 500 sheets. The weight of a ream of paper depends on the type of paper and its thickness. In this problem, we are given that a ream of printer paper weighs 5 1/4 pounds.

Now, Adam used 1/3 of a ream to print flyers. We can find the weight of the paper Adam used by multiplying 1/3 of the weight of a ream of paper by its weight:

Weight of paper used = (1/3) x 5 1/4 pounds

Weight of paper used = (5/3) x (1 1/4) pounds

Weight of paper used = 6 7/12 pounds

To find the weight of the remaining paper, we need to subtract the weight of the paper used from the weight of the full ream:

Weight of remaining paper = Weight of full ream - Weight of paper used

Weight of remaining paper = 5 1/4 pounds - 6 7/12 pounds

Weight of remaining paper = (21/4) pounds - (79/12) pounds

Weight of remaining paper = (21/4) pounds - (6 7/12) pounds

Weight of remaining paper = (21/4) pounds - (6 7/12) pounds

Weight of remaining paper = (84/12) pounds - (79/12) pounds

σ² = Σ(x - μ)² / N

σ² = Σ(x - μ)² / N

where:

σ² =  the population variance

Σ = the sum of

x = the value of each element in the population

μ = the population mean

N = the population size

First, we need to find the population mean:
