Answer:

5x - 6 = 5x - 7

5x - 6 = 5x - 6

5x - 6 = 9

Step-by-step explanation:

When you are looking for an equation with no solution, you only have to change the number without the variable. (5x - 6 = 5x - 7)

When you are looking for an equation with many solutions, you only have to write the exact same thing on the other side. (5x - 6 = 5x -6)

When you are looking for one solution, you don't use a variable and you only have to put a number that will give you a solution. (5x - 6 = 9)

To determine whether the series is absolutely convergent, conditionally convergent, or divergent, we need to evaluate the sum of the series. The given series is:

∞Σk=1 4k/(5k+k)

Simplifying the denominator, we get:

∞Σk=1 4k/(6k)

= ∞Σk=1 2/3

Since the summand is a constant value (2/3) and does not depend on k, the series is a divergent series.

Therefore, the given series is divergent.
Hi! To determine whether the series is absolutely convergent, conditionally convergent, or divergent, we will consider the given series:

Σ (4 / (5k)), where k = 1 to ∞

First, we'll examine absolute convergence by taking the absolute value of the series terms:

Σ |4 / (5k)| = Σ (4 / (5k))

Since the absolute value does not change the terms in this case, the series is the same. Now we'll apply the Ratio Test:

lim (n → ∞) |(4 / (5(k+1))) / (4 / (5k))|

= lim (n → ∞) (4 / (5(k+1))) * (5k / 4)

= lim (n → ∞) (5k / (5(k+1)))

= lim (n → ∞) (5k / (5k + 5))

= lim (n → ∞) (k / (k + 1))

= 1

The result of the Ratio Test is 1, which means the test is inconclusive. However, we can apply the Comparison Test with the harmonic series Σ (1 / k), which is known to be divergent. Since 4 / (5k) ≤ 1 / k for all k, and the harmonic series is divergent, the given series is also divergent by the Comparison Test.

So, the given series is divergent.

Answer:

x = 35

Step-by-step explanation:

Let x be the one of the other angles

X is also the third angle since we know they are equal

The sum of the angles of a triangle is 180

110+x+x = 180

110 +2x= 180

2x = 180-110

2x= 70

Divide by 2

2x/2 = 70/2

x = 35

Answer:

\(x = 35 \degree\)

Step-by-step explanation:

Let the unknown angle be x

Unknown Angles are equal to each other so,

\(x + x + 110 = 180\)

sum of the interior angles in a triangle is 180°

\(2x + 110 = 180 \\ 2x = 180 - 110 \\ 2x = 70 \\ \frac{2x}{2} = \frac{70}{2} \\ x = 35 \degree\)

The k-value represents the factor by which the old circumference has been multiplied to get the new circumference. To find the k-value, we can use the following formula , the k-value is approximately 1.16.

k = New Circumference / Old Circumference

To find the k-value, we need to use the formula:

new circumference = k x old circumference

Substituting the given values:

95 = k x 82

Solving for k:

k = 95/82

k = 1.1585

Rounding off to two decimal places, k ≈ 1.16

Therefore, the k-value is approximately 1.16.

b) The probability that Greer will refund more than $25 for a tire is 0.9

According to the Question:

Greer Tire Company has:

Lifetime mileage = 33500

Standard Deviation = 3500 miles

a)

Meal lifetime mileage : $33,500

Standard deviation of mileage $3,500

Observed miles 30,000 miles

(A) sample of 13 mature female pink seaperch was collected in winter, with a mean length of 109 millimeters and a standard deviation of 11 millimeters.

(B)  The critical value(s) and rejection region(s) are determined based on the significance level of 0.10 and the degrees of freedom

(c) The standard test statistic, also known as the t-value, is calculated using the formula:

t = (mean₁ - mean₂) / sqrt[(s₁²/n₁) + (s₂²/n₂)]

In order to determine whether the mean length of mature female pink seaperch is different in fall and winter, a hypothesis test is conducted with a significance level (alpha) of 0.10. The marine biologist collected a sample of 14 mature female pink seaperch in fall, with a mean length of 113 millimeters and a standard deviation of 10 millimeters. Another sample of 13 mature female pink seaperch was collected in winter, with a mean length of 109 millimeters and a standard deviation of 11 millimeters.

To support or refute the biologist's claim, the following steps are taken:

(b) The critical value(s) and rejection region(s) are determined based on the significance level of 0.10 and the degrees of freedom. Since the sample sizes are relatively small and the population variances are assumed to be equal, the appropriate test statistic to use is the t-distribution. The critical values are obtained from the t-distribution table or a statistical software. The rejection region(s) correspond to the extreme values in the tails of the t-distribution.

(c) The standard test statistic, also known as the t-value, is calculated using the formula:

t = (mean₁ - mean₂) / sqrt[(s₁²/n₁) + (s₂²/n²)]

where mean₁ and mean₂ are the sample means, s₁ and s₂ are the sample standard deviations, and n₁ and n₂ are the sample sizes.

By plugging in the given values, the standard test statistic is calculated.

In order to reach a conclusion about the biologist's claim, the test statistic is compared to the critical value(s) obtained in step (b). If the test statistic falls in the rejection region, the null hypothesis (mean length is the same in fall and winter) is rejected, providing support for the biologist's claim. Conversely, if the test statistic falls outside the rejection region, there is not enough evidence to support the claim, and the null hypothesis cannot be rejected.

To calculate the forecast for the next period using exponential smoothing, we can use the following formula:

Forecast for next period = (a * Actual demand) + [(1 - a) * Forecast for current period]

Given that the actual demand is 50, the forecast for the current period is 53, and the smoothing constant (a) is 0.2, we can plug in these values and solve for the forecast for the next period:

Forecast for next period = (0.2 * 50) + [(1 - 0.2) * 53]
Forecast for next period = 10 + 42.4
Forecast for next period = 52.4

Therefore, the answer to the first question is C. 52.4.

Regarding the second question, the parameter of the exponential smoothing model that provides the weight given to the most recent time series value in the calculation of the forecast value is known as the smoothing constant (option C).

Regarding the third question, the standard error of the estimate is the square root of SSE (option C).
Question 1: Using exponential smoothing, the forecast for the next period can be calculated using the formula:

Forecast = α(Actual demand) + (1-α)(Previous forecast)

where α is the smoothing constant.

In this case, Actual demand = 50, Previous forecast = 53, and α = 0.2. Plugging these values into the formula, we get:

Forecast = 0.2(50) + (1-0.2)(53) = 10 + 0.8(53) = 10 + 42.4 = 52.4

So, the answer is C. 52.4.

Question 6: A parameter of the exponential smoothing model that provides the weight given to the most recent time series value in the calculation of the forecast value is known as the:

C. smoothing constant.

Question 7: The standard error of the estimate is the:

As a rough estimate, 100g of sugar is equivalent to 0.5 cups of granulated sugar.

Conversion is the process of changing units of measurement from one system to another.

In this case, we need to convert 100g of sugar into cups. However, the conversion factor for sugar varies depending on factors such as the type of sugar and how densely it is packed. For instance, powdered sugar is denser than granulated sugar, and so the conversion factor will differ.

In general, one cup of granulated sugar weighs around 200g, which means that 100g of sugar is equivalent to 0.5 cups. However, it is essential to note that this conversion factor is approximate and can vary depending on the quality and type of sugar used.

What is long division method and its steps ?

When splitting huge numbers, the task is divided into several sequential parts using the long division approach. The dividend is divided by the divisor, just as in conventional division problems, and the result is known as the quotient; occasionally, it also produces a remainder.

We need to comprehend a few stages in order to divide. A vinculum or right parenthesis separates the dividend from the quotient, while a vertical bar separates the divisor from the dividend. Let's now go through the long division stages listed below to comprehend the procedure.

1. Take the dividend's first digit starting from the left . Verify if this digit exceeds or is equal to the divisor.

2. Next, divide it by the divisor, and write the result as the quotient on top.

3. Subtract the outcome from the digit, and then put the difference below.

Step 4: Decrease the dividend's subsequent digit (if present).

Step 5: Carry out Step 4 again.

The center of the circle will be (2, -5) and the radius of the circle will be 1 unit.

A circle can be characterized by its center's location and its radius's length.

Let the center of the considered circle be at the (h,k) coordinate.

Let the radius of the circle be 'r' units.

Then, the equation of that circle would be:

(x - h)² + (y - k)² = r²

The equation is given below.

x² - 4x + y² + 10y = -28​

Then the center and the radius of the circle will be

x² - 4x + 4 + y² + 10y + 25 = -28​ + 4 + 25

The cumulative probability of having x or fewer successes is 0.157.

To calculate the probability of 11 or fewer successes in 12 trials with a probability of success of 0.4, we can use the cumulative distribution function (CDF) of the binomial distribution. The CDF gives the cumulative probability of having x or fewer successes in n trials.

In this case, the cumulative probability of 11 or fewer successes in 12 trials is given by:

P(X <= 11) = ∑(12 choose i) * (0.4)^i * (0.6)^(12-i)

for i = 0, 1, 2, ..., 11

Where (12 choose i) is the number of ways to choose i successes out of 12 trials, and can be calculated as

12! / (i! * (12-i)!).

This can be calculated using a binomial cumulative distribution function calculator. The result should be approximately 0.157.
