The missing premise is "all dogs are non-cats." Therefore, the argument is true.

The given information and analyze the argument step-by-step.

1. Some non-poodles are not non-cats: This statement means that there are some animals that are not poodles and are also cats.

2. No cats are dogs: This statement means that there is no overlap between cats and dogs.

Now, let's try to determine if "some poodles are dogs" can be concluded from these premises:
Since no cats are dogs, it doesn't matter whether some non-poodles are not non-cats. Poodles are a breed of dog, so it's already a fact that poodles are dogs.

So, the answer is True: some poodles are dogs.

Answer:

Number of fish in 2006 = 845 fishes (Approx.)

Step-by-step explanation:

Given;

Number of fish in 2000 = 1,150 fishes

Decreasing rate = 5% per year

Find:

Number of fish in 2006

Computation:

Exponential decay function:

F = P[1-r]ⁿ

Number of year = 2006 - 2000

Number of year =  6 year

Number of fish in 2006 = 1,150[1-5%]⁶

Number of fish in 2006 = 1,150[1-0.05]⁶

Number of fish in 2006 = 1,150[0.95]⁶

Number of fish in 2006 = 1,150[0.735]

Number of fish in 2006 = 845.25

Number of fish in 2006 = 845 fishes (Approx.)

The equation for the least square regression line can be used to model the relationship between the independent variable (sepal length) and the dependent variable (sepal width) for the iris setosa species.

The least square regression line is represented by the equation:

y = mx + b

where y is the predicted value of the dependent variable (sepal width), x is the value of the independent variable (sepal length), m is the slope of the line, and b is the y-intercept. To find the values of m and b, you would need a dataset of sepal length and sepal width measurements for the iris setosa species. By using statistical software or calculators, you can perform a linear regression analysis on the dataset to obtain the values of m and b. These values can then be plugged into the equation to obtain the least square regression line for sepal width based on sepal length. The equation for the least square regression line with sepal length as the independent variable and sepal width as the dependent variable for iris setosa is y = mx + b, where y is the predicted value of sepal width, x is the sepal length, m is the slope of the line, and b is the y-intercept. The equation for the least square regression line, also known as the linear regression line, allows us to model the relationship between two variables by fitting a straight line to a given set of data points. In this case, we are interested in predicting the sepal width (dependent variable) based on the sepal length (independent variable) for the iris setosa species. To find the equation for the least square regression line, we need to perform a linear regression analysis on a dataset of sepal length and sepal width measurements for iris setosa. This analysis calculates the values of the slope (m) and the y-intercept (b) of the line that best fits the data. Once we have the values of m and b, we can plug them into the equation y = mx + b to obtain the least square regression line. This line represents the best-fit line that minimizes the sum of the squared differences between the observed values of sepal width and the predicted values based on sepal length.

In conclusion, the equation for the least square regression line with sepal length as the independent variable and sepal width as the dependent variable for iris setosa is y = mx + b. This equation allows us to predict the sepal width based on the sepal length by using the values of the slope (m) and y-intercept (b) obtained through a linear regression analysis on a dataset of iris setosa measurements.

The sum of the series correct to four decimal places is 7.0000

To approximate the sum of the series, we can use the ratio test. The ratio test states that if the limit of the ratio of consecutive terms approaches a number L, then the series converges if |L| < 1 and diverges if |L| > 1.

The nth term of the series is given by

\(T_n = (-1)^n (3n)(n!)\)

The consecutive terms is

\(R_n = T_{n+1}/T_n = (-1)^{n+1} (3n+3)(n+1) / (-1)^n (3n)(n!) \\= (-1)^{n+1} * 3 * (n+1) / (n!)\)

Taking the limit as n approaches infinity:

\(L = lim_{n - > \infty} \ R_n = lim_{n - > \infty} (-1)^{n+1} * 3 * (n+1) / (n!)\)

Since \((-1)^{n+1}\) alternates between -1 and 1, the limit approaches 0 and |L| < 1, which means the series converges.

To approximate the sum of the series, we can use a numerical method such as the Euler-Maclaurin formula. The formula approximates the sum of an infinite series by the sum of its first few terms and the remainder term:

\(\Sigma_n^\infty=1T_n \approx \Sigma_{i=1}^m T_i + R_m\)

where \(R_m\) is the remainder term that decreases as m increases

For example, let's choose m = 5:

\(\Sigma_{i=1}^5 T_i = T_1 + T_2 + T_3 + T_4 + T_5\)

= -3! + (-1) * 3 * 2! + (-1) * 2 * 3 * 1! + (-1) * 3 * 4! + (-1) * 4 * 3 * 2! = -6 + 6 - 2 + 24 - 24 = -2

The remainder term \(R_m\) can be estimated using the Euler-Maclaurin formula:

\(R_m = -B_{2m} / (2m)! * T_{m+1}\)

where B_k are the Bernoulli numbers.

For \(m = 5, B_2m = B_{10} = -1/252\), so

\(R_m = -B_{10} / (10)! * T_{m+1} = -1/252 * (-1)^6 * 3 * 6! = 1/252 * 3 * 720 = 9\)

Therefore, the sum of the series is approximately

\(\Sigma_{i=1}^\Infty T_i \approx \Sigma_{i=1}^5 \ T_i + R_m \\= -2 + 9 = 7\)

To four decimal places, this is 7.0000

Answer: 1/50

Step-by-step explanation:

Step 1: We need to multiply the numerator and denominator by 100 since there are 2 digits after the decimal.

0.02 = (0.02 × 100) / 100

= 2 / 100 [ since 0.02 × 100 = 2 ]

Step 2: Reduce the obtained fraction to the lowest term

Since 2 is the common factor of 2 and 100 so we divide both the numerator and denominator by 2.

2/100 = (2 ÷ 2) / (100 ÷ 2) = 1/50

By analyzing the given information, it can be determined that 90% of the small town's population, which consists of 3000 inhabitants, will have heard the rumor by approximately 1:30 PM.

The initial information states that at 8 AM, 240 people had heard the rumor. This implies that (240/3000) * 100 = 8% of the town's population knew about the rumor at that time. By noon, half of the town has heard the rumor, meaning 50% of 3000 inhabitants or 1500 people have heard it. This indicates that the rumor spread to an additional (1500-240) = 1260 people during this time frame.

To determine the time when 90% of the town's population will have heard the rumor, we can calculate the percentage increase from the initial 8% to 90%. The difference between these percentages is 90% - 8% = 82%. Since 1260 people heard the rumor between 8 AM and noon, it is reasonable to assume a similar rate of increase for the remaining 82% of the population.

To find the time, we can calculate the time it took for the initial 8% to increase to 82% by dividing the increase in percentage (82%) by the increase in people (1260). This gives us (82/1260) = 0.0651 percentage increase per person. To reach 82% (90% - 8%) of the population, we can divide 82% by 0.0651, resulting in approximately 1260 / 0.0651 = 19344 people.

Since the initial 240 people heard the rumor at 8 AM and an additional 1260 people heard it by noon, the total number of people who have heard the rumor by noon is 240 + 1260 = 1500. To reach 19344 people, the rumor will need to spread to 19344 - 1500 = 17844 more people.

Considering the similar rate of increase, it can be estimated that it will take the same amount of time to reach this additional number of people as it took to reach the first 1500 people. Hence, by extrapolating this, it can be approximated that by approximately 1:30 PM, 90% of the small town's population will have heard the rumor.

The true size of a block with a nominal size of 6x4x16 may vary. The nominal size refers to the intended dimensions, but the actual size can differ due to manufacturing tolerances and other factors.

The nominal size of 6x4x16 indicates the intended dimensions of the block, with a length of 16 units, width of 6 units, and height of 4 units. However, the true size of the block can vary from the nominal size due to manufacturing tolerances and other factors.

Manufacturing processes may introduce slight variations in the actual dimensions of the block. These variations are commonly referred to as tolerances. Tolerances account for potential deviations from the intended dimensions and are necessary to accommodate practical considerations during manufacturing.

Therefore, without specific information on the tolerances or manufacturing specifications, it is not possible to determine the true size of a block with a nominal size of 6x4x16. The true size can vary within an acceptable range based on manufacturing tolerances and other factors.

C) y = 2x + 3

Step-by-step explanation:

In slope intercept form(y = mx + b), b is the y intercept and m is the slope. The y intercept is y variable when the x variable is 0. In the chart, the y-intercept(b) is 3. Slope is identified by the different in y by the difference in x. In this chart the slope is 2. Now plug in the number into slope intercept form( y = 2x + 3).

Applying the inscribed angle theorem, the value of x in the circle is: 126°.

According to the inscribed angle theorem, the measure of the inscribed angle, 63° is one-half of the measure of central angle, x, as shown in the circle given.

Therefore, we would have the following equation:

With an 80% improvement in typing speed from an initial rate of 50 words per minute, you will be able to type 90 words per minute.

Increasing your typing speed by 80% means you will be able to type 80% more words in the same amount of time. Therefore, if your initial typing speed is 50 words per minute, an 80% improvement would result in a typing speed of 90 words per minute.

To calculate the new typing speed, we first find 80% of the initial typing speed.

80% of 50 is (80/100) * 50 = 0.8 * 50 = 40.

This means that your typing speed will increase by 40 words per minute.

To determine the new typing speed, we add the increase to the initial typing speed:

50 + 40 = 90.

Thus, after the 80% improvement, you will be able to type 90 words per minute.

In summary, with an 80% improvement in typing speed from an initial rate of 50 words per minute, you will be able to type 90 words per minute.
