The correct option is B) Not valid. Consider the statement “Since some shoes are sneakers, some non-sneakers are non-shoes.”

We know that all sneakers are shoes, but all shoes are not sneakers.  Hence, some shoes are sneakers. But, this statement does not imply that “some non-sneakers are non-shoes.” This inference cannot be drawn by contraposition. So, it is not valid.Inferences cannot be drawn in contraposition all the time. Contraposition is a type of logical statement that involves reversing and negating the terms of an original proposition. It is a logical relationship between a proposition and its converse. If a proposition is true, the contrapositive is always true.An example of contraposition can be shown as follows:“If a person is a human, then they are mortal.”We can write the contrapositive of this statement as:“If a person is not mortal, then they are not human.”

Answer:

The coordinates of the other point are:

(x₂, y₂) = (18, 20)

Hence, option A is correct.

Step-by-step explanation:

Given

To determine

Using the Mid-point formula between (x₁, y₁) and (x₂, y₂)

\(\left(x,\:y\right)=\:\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)\)

Here:

(x, y) is the midpoint between (x₁, y₁) and (x₂, y₂)

substituting (x, y) = (0, 5) and (x₁, y₁) = (-18, -10) in the formula

\(\left(0,\:5\right)=\:\left(\frac{x_2+\left(-18\right)}{2},\:\:\frac{y_2+\left(-10\right)}{2}\right)\)

equating

\(0=\frac{x_2+\left(-18\right)}{2}\)

\(x_2-18=0\)

Add 18 to both sides

\(x_2-18+18=0+18\)

\(x_2=18\)

also

\(5=\frac{y_2+\left(-10\right)}{2}\)

\(10=y_2+\left(-10\right)\)

\(10=y_2-10\)

\(10+10=y_2\)

\(10+10=y_2\)

\(y_2=20\)

Therefore, the coordinates of the other point are:

(x₂, y₂) = (18, 20)

Hence, option A is correct.

Answer:

(x₂, y₂) = (18, 20)

The correct answer is: "Anova has less risk of a Type I error because several means are compared in one test."

When comparing more than two treatment conditions, using analysis of variance (ANOVA) is preferred over conducting separate t-tests.

This is because ANOVA allows for the simultaneous comparison of multiple means in a single test, reducing the chances of making Type I errors (false positives).

When conducting multiple t-tests, the probability of incorrectly rejecting the null hypothesis increases with each comparison made. By using ANOVA, the overall risk of making a Type I error is controlled, as the test takes into account the variability within and between groups.

This helps to minimize the likelihood of falsely detecting significant differences between groups.

It's important to note that ANOVA does not inherently have a lower risk of Type II errors (false negatives) compared to t-tests.

The sensitivity of a test, which refers to its ability to correctly detect true effects, depends on various factors such as sample size, effect size, and statistical power, rather than the choice of ANOVA or t-tests.

The interval of convergence for the given power series is (2, 8).

To find the interval of convergence for the given power series. We have the power series:

∑(n=2 to ∞) ((x-5)ⁿ)/(3ⁿ)

To find the interval of convergence, we'll use the Ratio Test. For the Ratio Test, we need to compute the limit:

L = lim (n → ∞) |(a_(n+1)/a_n)|

For our series, a_n = ((x-5)ⁿ)/(3ⁿ). Therefore, a_(n+1) = ((x-5)(n+1))/(3(n+1)). Now, let's compute the ratio:

|(a_(n+1)/a_n)| = |(((x-5)(n+1))/(3(n+1))) / (((x-5)ⁿ)/(3ⁿ))|

Simplify the expression:

|(a_(n+1)/a_n)| = |(x-5)/3|

The series converges if L < 1. So we have:

|(x-5)/3| < 1

Now, we'll solve for x to find the interval of convergence:

-1 < (x-5)/3 < 1

Multiply each term by 3:

-3 < x-5 < 3

Add 5 to each term:

2 < x < 8

Step-by-step explanation:

The period of a simple pendulum is 1 s on Earth. when brought to a planet where g is one-tenth that on earth, its period becomes (d) 1/√10 s.

The period of a simple pendulum is given by the equation T = 2π√(L/g), where T is the period, L is the length of the pendulum, and g is the acceleration due to gravity.

On Earth, the period is 1 s, which means that 1 = 2π√(L/gEarth).

When the same pendulum is taken to a planet where g is one-tenth that on Earth, the equation becomes T = 2π√(L/(g/10)).

We want to find the new period, so we can solve for T: T = 2π√(L/(g/10)) = 2π√(10L/g).

We know that the length of the pendulum does not change, so we can substitute L from the first equation into the second equation: T = 2π√(10/gEarth).

We can simplify this equation by dividing the numerator and denominator of the square root by gEarth:

T = 2π√(10/gEarth) * (√gEarth/√gEarth) = 2π√(10gEarth/gEarth^2) = 2π√(10/9.81) s.

Therefore, the answer is (d) 1/√10 s.

Step-by-step explanation:

We are to find the first five sequence

when n = 1

f(2) = f(1) - 19

f(2) = 34 - 19

f(2) = 15

when n = 2

f(2+1) = f(2) - 19

f(3) = f(2) - 19

f(3) = 15 - 19

f(3) = -4

when n = 3

f(3+1) = f(3) - 19

f(4) = f(3) - 19

f(4) = -4 - 19

f(4) = -23

when n = 4

f(4+1) = f(4) - 19

f(5) = f(4) - 19

f(5) = -23 - 19

f(5) = -42

Hence the first five terms  in the arithmetic sequence are 34, 15, -4, -23 and -42

The volume of the triangular prism that h = 8m, b = 10m, l = 22m is 880 cubic meters.

To find the volume of a triangular prism, we first need to find the area of the base triangle, which is given by the formula:

A = (1/2) × b × h

where b is the base and h is the height of the triangle.

In this case, the base of the triangular prism is a triangle with base b = 10m and height h = 8m, so its area is:

A = (1/2) × 10m × 8m = 40m²

The volume of the triangular prism is then given by multiplying the area of the base by the length of the prism:

V = A × l

where l is the length of the prism.

In this case, the length of the triangular prism is l = 22m, so its volume is:

To determine if a function crosses the horizontal asymptote, analyse the behavior of the function as it approaches the asymptote and on either side of it.

1. Identify the horizontal asymptote of the function. The horizontal asymptote is a horizontal line that the function approaches as the independent variable (usually denoted as x) goes to positive or negative infinity. It is often denoted by a horizontal line y = a, where "a" is a constant.

2. Examine the behavior of the function as x approaches positive infinity. Evaluate the limit of the function as x goes to positive infinity. If the limit is equal to the value of the horizontal asymptote, then the function does not cross the asymptote. However, if the limit does not equal the asymptote, move to the next step.

3. Examine the behavior of the function as x approaches negative infinity. Evaluate the limit of the function as x goes to negative infinity. If the limit is equal to the value of the horizontal asymptote, then the function does not cross the asymptote. If the limit does not equal the asymptote, proceed to the next step.

4. Investigate the behavior of the function around critical points or points where the function changes its behavior. These points may include the x-intercepts or vertical asymptotes. Determine if the function crosses the asymptote around these points by analyzing the behavior of the function in their vicinity.

If, at any point in this process, the function crosses the horizontal asymptote, then it does not have a true horizontal asymptote. However, if the function approaches the asymptote and does not cross it at any point, then it has a horizontal asymptote.

It's important to note that some functions may have multiple horizontal asymptotes or no horizontal asymptote at all. The steps outlined above are a general guideline, but the specific behavior of the function needs to be analyzed to make a conclusive determination.

Answer:

Step-by-step explanation:

The storage bin is in the shape of a rectangular prism.

Its volume is 5400 cubic inches and its base area is 450 square inches.

The volume of a rectangular prism is given as:

V = L * W * H

where L = length

W = width

H = height

The product of the length and width gives the base area of the rectangular prism:

A = L * W

This implies that:

V = A  * H

=> 5400 = 450 * H

H = 5400 / 450

H = 12 inches

The height of the bin is 12 inches.

The amount of liquid that can be processed in 2 hours at a unit rate of 1 gallon per 18.25 minutes is calculated to be approximately 6.58 gallons.

Assuming the unit rate of 1 gallon per 18.25 minutes, we can convert 2 hours to minutes by multiplying it by 60, which gives us 120 minutes.

So, in 120 minutes, the amount of liquid that can be processed at a unit rate of 1 gallon per 18.25 minutes would be:

(120 minutes) / (18.25 minutes/gallon) = 6.58 gallons
