Step-by-step explanation:

The sum of an infinite geometric series is given by a+ar+ar^2  where a is the first term and r is the common ratio.

The sum of the series  can be represented by :

a / ( 1 - r)  = 12

a = 12 ( 1- r )    (1)

So....note that the sum of the  terms  with odd powers of r  can be represented by :

ar  + ar^3  + ar^5 + ar^7 +  ..... + ar^(2n - 1)  =  5   (2)

And note that the sum of the  terms  with even powers of r  can be represented by :

a  +  ar^2  + ar^4 + ar^6 + ar^8 +  ..... + ar^(2n)  =  7   (3)

Multiply (2)  by r on both sides

ar^2  + ar^4  + ar^6 + ar^8 +  ..... + ar^(2n )  =  5r     (4)

Subtract   (4)  from (3)

a  = 7 - 5r    (5)

Sub (5)  into (1)

7 - 5r  = 12(1 - r)

7 - 5r  =  12 - 12r

7r = 5     →   r  =  5/7

Check

a = 7 - 5(5/7)  =  24/7

a / ( 1 - r)  =

(24/7) / ( 1- 5/7)  =

(24/7) / ( 2/7)  =

24 / 2   =

Answer:

the ordered pair (0, 1/6)

Step-by-step explanation:

To reflect a function across the y-axis, we replace every occurrence of x with -x. Therefore, the function g(x) is given by:

g(x) = f(-x) = 1/6(2/5)^(-x)

To find an ordered pair on g(x), we need to choose a value of x and evaluate g(x). For example, if we choose x = 0, then:

g(0) = 1/6(2/5)^(-0) = 1/6

Therefore, the ordered pair (0, 1/6) is on the graph of g(x).

Answer:

Vertical compression of One-half, horizontal stretch to a period of 4 pi, vertical shift of 1 unit up and a phase shift of pi units left

Step-by-step explanation:

The parameters of the sine function are;

The point the curve crosses the y-axis (at x = 0) = 1.5

The minimum of the curve is y = 0.5

The maximum is y = 1.5

The time it goes through one cycle = 4 pi

The general form of the sine function is presented as follows;

y = A·sin(B·(x - C)) + D

From the given information, we have;

A = 0.5

The period = 4·π = 2·π/B

∴ B = 1/2

At x = 0, y = max, therefore, B·(x - C) = (1/2)·(0 - C) = π/2

∴ C = -π

D = 1

Therefore, the given sine function can be presented as follows;

y = 0.5·sin((1/2)·(x - π)) + 1

Therefore, the transformation needed to change the parent sine function to the given sine function are

Vertical compression of One-half, horizontal stretch to a period of 4 pi, vertical shift of 1 unit up and a phase shift of pi units left

Based on the chi-square test, there is no significant evidence to suggest that the die is not balanced.

We have,

To determine if the die is balanced, we can perform a chi-square test of goodness of fit.

The null hypothesis is that the die is balanced, and the alternative hypothesis is that the die is not balanced.

First, let's calculate the expected frequencies for each outcome assuming the die is balanced. Since there are 180 tosses in total, each outcome is expected to have an equal probability of 1/6.

Expected frequency for each outcome

= (Total tosses) x (Probability of each outcome)

Expected frequency for each outcome = (180) x (1/6)

Expected frequency for each outcome = 30

Now, we can calculate the chi-square test statistic using the formula:

χ² = Σ [(Observed frequency - Expected frequency)² / Expected frequency]

Let's calculate the chi-square test statistic:

χ² = [(28 - 30)² / 30] + [(36 - 30)² / 30] + [(36 - 30)² / 30] + [(30 - 30)² / 30] + [(27 - 30)² / 30] + [(23 - 30)² / 30]

χ² = [(-2)² / 30] + [(6)² / 30] + [(6)² / 30] + [(0)² / 30] + [(-3)² / 30] + [(7)² / 30]

χ² = 4/30 + 36/30 + 36/30 + 0/30 + 9/30 + 49/30

χ² = 134/30

χ² ≈ 4.467

Next, we need to compare the calculated chi-square value to the critical chi-square value at a significance level of 0.01 and degrees of freedom equal to the number of outcomes minus 1 (6 - 1 = 5).

Looking up the critical chi-square value in a chi-square distribution table with 5 degrees of freedom and a significance level of 0.01, we find it to be approximately 15.086.

Since the calculated chi-square value (4.467) is less than the critical chi-square value (15.086), we fail to reject the null hypothesis.

Therefore, we do not have sufficient evidence to conclude that the die is not balanced at a 0.01 level of significance.

Thus,

Based on the chi-square test, there is no significant evidence to suggest that the die is not balanced.

The probability that a randomly selected LMU student would have a height greater than 68 inches is 0.0668 or 6.68%.

To determine the probability that a randomly selected LMU student would have a height greater than 68 inches, you can use the standard normal distribution.
The standard normal distribution is a normal distribution with a mean of 0 and a standard deviation of 1. To convert the given normal distribution with mean 65 inches and standard deviation 2 inches to the standard normal distribution, you can use the formula: z = (x - μ) / σ
where z is the z-score, x is the value you want to convert, μ is the mean, and σ is the standard deviation.Using this formula, you can find the z-score corresponding to a height of 68 inches as follows: z = (68 - 65) / 2 = 1.5. The probability of a randomly selected student having a height greater than 68 inches can be found by looking up the area to the right of the z-score of 1.5 in the standard normal distribution table. The table gives the area to the left of the z-score, so to find the area to the right of the z-score, you can subtract the area to the left from 1: P(z > 1.5) = 1 - P(z < 1.5)
Using the standard normal distribution table, you can find that the area to the left of the z-score of 1.5 is 0.9332. Therefore, the area to the right of the z-score is 1 - 0.9332 = 0.0668 or 6.68%.

Thus, the probability that a randomly selected LMU student would have a height greater than 68 inches is 0.0668 or 6.68%.

Geometrically, S represents a plane in ℝ^3 that is orthogonal (perpendicular) to the vector m.

To establish that S is a subspace of ℝ^3, we must confirm that S is closed under vector summation and scalar multiplication.

A pertinent theorem from linear algebra that can be applied here is the "Subspace Criterion" theorem. This principle states that a non-empty subset S of a vector space V is a subspace if and only if it fulfills the following conditions:

For any vectors a, b ∈ S, their addition a + b ∈ S.

For any vector a ∈ S and any scalar k, the product ka ∈ S.

Now, let's define a vector m = v - e.

Observe that for any y in S, we have:

m • y = (v - e) • y = (v • y) - (e • y) = 0.

This implies that y is orthogonal to the vector m.

To find the limit of \((11x + 21) / (7x + 6 - x^2)\) as x approaches negative infinity, we can simplify the expression and apply the properties of limits.

First, let's factor out \(-x^2\) from the denominator:

\((11x + 21) / (7x + 6 - x^2) = (11x + 21) / (-x^2 + 7x + 6)\)

Now, let's divide both the numerator and denominator by x^2:

\((11/x + 21/x^2) / (-1 + 7/x + 6/x^2)\)

As x approaches negative infinity, the terms 11/x and \(21/x^2\) approach 0, and the terms 7/x and \(6/x^2\) also approach 0. Therefore, we can simplify the expression to:

0 / (-1 + 0 + 0) = 0 / (-1) = 0

Hence, the limit of (11x + 21) / \((7x + 6 - x^2)\) as x approaches negative infinity is 0.

the expectation of buying one ticket is $2

Expectation if a person buys one ticket A person is interested in buying a ticket for a lottery that offers one $1000 prize, one $500 prize, and five $100 prizes. One thousand tickets are sold at $3 each. The expected return is calculated using the following formula:

Expectation = (Probability of winning Prize 1 × Value of Prize 1) + (Probability of winning Prize 2 × Value of Prize 2) + (Probability of winning Prize 3 × Value of Prize 3)To determine the expectation, we must first determine the probability of winning each of the three prizes.

Since one thousand tickets are sold and only one person can win the first prize, the probability of winning the $1000 prize is 1/1000 or 0.001. Similarly, the probability of winning the $500 prize is 1/1000 or 0.001. Since five $100 prizes are available and only one person can win each prize, the probability of winning any one of the five $100 prizes is 5/1000 or 0.005.

Therefore, the expectation is calculated as follows: Expectation = (0.001 × $1000) + (0.001 × $500) + (0.005 × $100)Expectation = $1 + $0.50 + $0.50Expectation = $2Thus, the expectation of buying one ticket is $2. This means that the average value of a ticket is $2, and a person can expect to win $2 on average by purchasing a ticket. Since the cost of a ticket is $3, the expected return is less than the cost of the ticket, and therefore, it is not a good investment from a financial standpoint.

To determine whether to reject or fail to reject the null hypothesis, we typically rely on statistical hypothesis testing. After conducting a hypothesis test, we consider the test statistic and the corresponding p-value.

When the p-value is less than or equal to the predetermined significance level (usually denoted as α), we reject the null hypothesis. This indicates that the observed data provides sufficient evidence to support the alternative hypothesis. Conversely, when the p-value is greater than the significance level, we fail to reject the null hypothesis. In this case, we do not have enough evidence to support the alternative hypothesis.

The significance level α is predetermined and represents the probability of making a Type I error, which is the rejection of the null hypothesis when it is actually true. Commonly used significance levels include 0.05 (5%) and 0.01 (1%). The choice of the significance level depends on the specific research context and the consequences of making a Type I error.

It is important to note that failing to reject the null hypothesis does not necessarily mean that the null hypothesis is true. It simply means that the observed data does not provide enough evidence to support the alternative hypothesis. There could still be other factors or limitations in the study that contribute to the lack of significant results.

The sum Σ (1)/(n(n-1)) can be written as a telescoping series, and when n = 5, the sum is 29/30.

First, we can write the partial fraction decomposition of (1)/(n(n-1)) as:

(1)/(n(n-1)) = 1/(n-1) - 1/n

Then, we can use this expression to write Σ (1)/(n(n-1)) as a telescoping series:

Σ (1)/(n(n-1)) = (1/10) - (1/11) + (1/21) - (1/22) + (1/32) - (1/33) + ...

Notice that each term cancels out with the next term in the series, leaving only the first and last terms:

Σ (1)/(n(n-1)) = (1/10) - (1/11) + (1/21) - (1/22) + (1/32) - (1/33) + ... - (1/(n-1)n) + (1/n(n+1))

Now, we can substitute n = 5 to get:

Σ (1)/(n(n-1)) = (1/10) - (1/11) + (1/21) - (1/22) + (1/32) - (1/33) - (1/45) + (1/56)

Simplifying this expression, we get:

Σ (1)/(n(n-1)) = 1 - 1/5*6

Σ (1)/(n(n-1)) = 1 - 1/30

So when n = 5, the sum of the series is S5 = 1 - 1/30 = 29/30.
