Step-by-step explanation:

the correct way to report the results of a hypothesis test and a measure of effect size using a t-statistic is option A: t(19)=2.30, r2=0.42, p<0.05.

The correct way to report the results of a hypothesis test and a measure of effect size using a t-statistic depends on the specific journal or style guide you are using. However, in general, the most common format is to report the t-value, degrees of freedom, and p-value first, followed by the measure of effect size.

So, looking at the options provided, we can eliminate option D because it only reports the t-value, degrees of freedom, p-value, and effect size all at once without separating them. Now, we are left with options A and B. Both options report the t-value, degrees of freedom, and p-value first, followed by the effect size. However, there is a difference in the order of the p-value and effect size. Option A reports the effect size as r2=0.42 after the p-value, while option B reports the effect size as r2=0.42 before the p-value.

The possible value of positive constant b for an absolute maximum value of function g(x), \(g(x) = xe^{-x} + be^{-x} \) at x = \( \frac{2}{3} \) is equals to the \( \frac{1}{3} \).

An absolute maximum point is a point where the function acquires its largest possible value. To drive the max or min absolute value, we have to substitute the derivative value of function equals to zero. We have a function, \(g(x) = xe^{-x} + be^{-x} \), where b is positive constant. We have to determine the possible value of b for absolute maximum of g at x= 2/3.

Differentiating the function g(x) with respect to x

=> \(g'(x) = - x e^{-x} + e^{-x} - be^{-x} \)

\(= (1 - x - b )e^{-x}\)

\(= \frac{1 - x - b }{e^{x}}\)

For obtaining absolute maximum value put, g'(x) = 0

=> \(\frac{1 - x - b }{e^{x}} = 0\)

Substitute x = 2/3, in above expression,

\( \frac{1 - \frac{2}{3} - b }{e^{\frac{2}{3}}} = 0\)

=> \(1 - \frac{2}{3} - b = 0\)

=> \( b = \frac{1}{3}\)

Hence, the required value of b is \( \frac{1}{3} \).

The radius of the spherical part is 3 inches and the length of the tube is 21 cm.

The capacity of a cylinder, which determines how much material it can hold, is determined by the cylinder's volume. There is a formula for the volume of a cylinder that is used in geometry to determine how much of any quantity, whether liquid or solid, can be immersed in it uniformly.

Given that the volume when the water is fully dipped is 4554 / 7 cm³. The volume when the length is 9 cm empty is 396 cm³.

The two equations can be formed as below:-

4554 / 7 = πr²l + (2/3)πr³

396 = πr²( l - 9 ) + (2/3)πr³

Subtract the second equation from the first,

( 4554 / 7 ) - 396 = 9πr²

9πr² = 254.5

r² = 9

r = 3 cm

The length will be calculated as:-

4554 / 7 = πr²l + (2/3)πr³

4554 / 7 = π( 3 )²l + (2/3)π(3)³

l = 21 cm

Therefore, the tube's length is 21 cm, and the spherical part's radius is 3 inches.

The function dependency A -> B for relation schema R(A,B,C,D) implies that:
d. Any two tuples in R that have the same value for A must have the same value for B

The correct answer is option d. This is because the function dependency A -> B means that the value of B is functionally dependent on A.  The productivity function X → Y is called trivial if Y is part of X. In other words, the FD:X → Y dependency means that the value of Y is determined by the value of X. Two bunches of X values ​​that share the same thing must have the same Y value where Z = U - XY is the residue. In simple terms, if the values ​​of the X attributes are known (assuming they are x), then the values ​​of the Y attributes corresponding to x can be determined by looking at them in an R tuple containing x.

Therefore, any two tuples in R that have the same value for A must have the same value for B. This ensures that the relationship is functional and follows the rules of normalization. Tuples are individual rows in a relation and value refers to a specific entry in a tuple for a particular attribute.

To determine which differential equation(s) are linear, we need to examine the form of each equation. A linear differential equation is one that can be written in the form a(x)y" + b(x)y' + c(x)y = g(x), where a(x), b(x), c(x), and g(x) are functions of x.

The differential equation 2xy" - 5xy' + y = sin(3x) is linear. It can be written in the form a(x)y" + b(x)y' + c(x)y = g(x), where a(x) = 2x, b(x) = -5x, c(x) = 1, and g(x) = sin(3x).
The differential equation (v)² + xy = In(x) is not linear. It does not follow the form a(x)y" + b(x)y' + c(x)y = g(x) because it contains a term with (v)², where v represents the derivative of y with respect to x. This term does not have a linear coefficient.
The differential equation y' + sin(y) = e^(3x) is linear. It can be written in the form a(x)y' + b(x)y = g(x), where a(x) = 1, b(x) = sin(y), and g(x) = e^(3x).
The differential equation (x²+1)y" - 3y - 2x³y = -x - 9 is not linear. It does not follow the form a(x)y" + b(x)y' + c(x)y = g(x) because it contains a term with (x²+1)y", where the coefficient is a function of x.
The differential equation y' + xy = y" is linear. It can be written in the form a(x)y' + b(x)y = g(x), where a(x) = 1, b(x) = x, and g(x) = y".

The standard error of the mean for this random sample of 100 customers is 0.1.

The correct option is C.

The standard error of the mean is a measure that indicates the precision or variability of the sample mean in relation to the population mean. It represents the average amount of sampling error we can expect when estimating the population means based on a sample.

To calculate the standard error of the mean, we divide the standard deviation of the population by the square root of the sample size. In this case, the standard deviation is 1 minute and the sample size is 100.

Dividing 1 by the square root of 100, we get 1/10 or 0.1. This means that the standard error of the mean for this sample is 0.1.

A smaller standard error of the mean indicates that the sample mean is a more accurate estimate of the population mean. In this case, a standard error of 0.1 suggests that the average length of time it took customers to check out may vary around the sample mean by approximately 0.1 minutes.

Answer:

324 square meters

Step-by-step explanation:

Hey there!

The surface area of a shape is the area of all the surfaces added up

The side surface area is 48 since 16 x 3 is 48. Since there are two side areas, we need to multiply 48 x 2 is 96

Now we need to do this for the other sides

the bottom and top areas are 96 square meters each so we multiply 96 by 2 which is 192

The front and back faces have an area of 18 square meters so we multiply 18 by 2 since there are two faces which are 36

Now we add all the values: 96+192+36 which is 324

So the surface area of the prism is 324 square meters

The probability of a late departure or an early arrival P(late departure or early arrival) = 0.12 + 0.27 – 0.04

The probability is defined as the chances of occurence of any event from the sample.

Given: The probability of a late departure is 12 %t, the probability of early arrival is 27%.

i.e. P(late departure)=0.12

P(an early arrival)=0.27

The probability of both a late departure and an early arrival is 4 percent.

P(late departure and early arrival) =0.04

Now, using the formula the probability of the union of two dependent events A and B:-

\(\rm P(AUB)=P(A)+P(B)-P(A \cap B)\)

The intrinsic value of the PUT option is $0. It means the option has no inherent value based on the given information.

To determine the intrinsic value of a PUT option, we compare the strike price (X) with the current market price (S) of the underlying asset. If the strike price is higher than the market price, the intrinsic value is the difference between the strike price and the market price. However, if the market price is higher than the strike price, the intrinsic value is $0.

In the given information, we have the following data:

- Strike price (X): $90

- Market price (S): $47.78

Since the market price is lower than the strike price (47.78 < 90), the intrinsic value of the PUT option is $0. This means that exercising the option would not result in any profit because it is currently out of the money.

The probability of getting a score of 80% or higher is 0.18750.

We are given that;

The probability of getting a score = 80%

Now,

We can use the binomial probability formula:

\($$P(X) = {n \choose x} p^x (1-p)^{n-x}$$\)

where P(X) is the probability of getting x successes out of n trials, p is the probability of success on each trial and (1-p) is the probability of failure on each trial.

In this case, we have:

n = 5 the number of questions on the quiz

x = 4 or x = 5, the number of correct answers needed to get 80% or higher

p = 0.5, the probability of guessing correctly on each question

(1-p) = 0.5, the probability of guessing incorrectly on each question

So, we can plug these values into the formula and calculate the probabilities for x = 4 and x = 5:

\($$P(X=4) = {5 \choose 4} (0.5)^4 (0.5)^{5-4} = \frac{5!}{4!(5-4)!} (0.5)^4 (0.5)^1 = \frac{5}{1} (0.0625) (0.5) = 0.15625$$$$P(X=5) = {5 \choose 5} (0.5)^5 (0.5)^{5-5} = \frac{5!}{5!(5-5)!} (0.5)^5 (0.5)^0 = \frac{1}{1} (0.03125) (1) = 0.03125$$\)

To find the probability of getting 80% or higher, we need to add these two probabilities:

\($$P(X \geq 4) = P(X=4) + P(X=5)\)

= 0.15625 + 0.03125 = 0.18750$$

Therefore, by probability the answer will be 0.18750.
