Answer: D. 2/3

Step-by-step explanation:

If it is 1/5 of an hour, we times it by 5, to get full hour, right?

So, we also do ×5 for the acre of land, so we can get the amount of acres in a full 1 hour.

5 is the same as 5/1 as a fraction

1/5 × 5 = 5/5 ......1 hour

2/15 × 5/1 = 10/15

So we get, 10/15 acre of land cleared in 1 hour

We simplify 10/15,

Which becomes,

2/3.

In conclusion, this is the working out =

2/15 × 5 = 10/15 = 2/3

As given:

The side of the Square= (2x+

As we know:

The area of a square = Side × side

Putting the values of side in above formula we get:

 Area = (2x+4) ×(2x+4)

on solving we get:

Area= 2x×2x + 2x×4 +4×2x + 4×4

Area= 4x^2 + 8x + 8x + 16

Area= 4x^2 + 16x + 16

Hence,The Area of the Square is (4x^2+ 16x +16)

This is a contradiction, so our original assumption that g(x) = f(x) must be false. Therefore, the solution is not true algebraically.

What are functions ?

In mathematics, a function is a rule that maps each element in a set (the domain) to a unique element in another set (the range). It is a relation between a set of inputs and a set of possible outputs with the property that each input is related to exactly one output. Functions are commonly represented using function notation, where the symbol "f" is used to represent the function, and the input value is placed inside parentheses. For example, if the function takes the input "x" and returns the output "y"

According to the question:
To prove algebraically that g(x) = f(x), we need to show that the expressions for g(x) and f(x) are equivalent for all values of x. That is, we need to show that:

2x²+3x-1 = x²-3

We can start by simplifying both sides of the equation:

2x²+3x-1 - (x²-3) = 0

Simplifying the left side, we get:

2x²+3x-1 - x²+3 = x²+3x+2

Now we can simplify the right side:

x²+3x+2 = (x+1)(x+2)

Substituting this expression back into the equation, we get:

2x²+3x-1 - x²+3 = (x+1)(x+2)

Simplifying the left side again, we get:

x²+3x-4 = (x+1)(x-4)

Now we have:

(x+1)(x-4) = (x+1)(x+2)

We can cancel out the factor of (x+1) from both sides, since it is not equal to zero for any value of x:

x-4 = x+2

Subtracting x from both sides, we get:

-4 = 2

This is a contradiction, so our original assumption that g(x) = f(x) must be false. Therefore, the solution is not true algebraically.

The journal could use a one-tailed hypothesis test with a significance level (α) of 0.05 to determine whether there is a significant difference between the proportion of women and men.

In statistics, the p-value is a measure of the evidence against the null hypothesis. It is the probability of observing a test statistic as extreme as, or more extreme than, the one calculated from the sample data, assuming that the null hypothesis is true. In other words, the p-value is the probability of obtaining the observed results, or more extreme results, if the null hypothesis were true.

Given by the question.

To test the claim that women perceive the gender equality problem to be much more compared to men, the journal could test the following hypothesis:

Hypothesis: The proportion of women who perceive gender equality to be a major problem in the workplace (W) is significantly greater than the proportion of men who perceive gender equality to be a major problem in the workplace (M).

H0: W = M (there is no significant difference in perception of gender equality between men and women)

Ha: W > M (women perceive gender equality to be a major problem more than men do)

who perceive gender equality to be a major problem in the workplace. They could calculate the p-value and compare it to α. If the p-value is less than α, they would reject the null hypothesis and conclude that the proportion of women who perceive gender equality to be a major problem in the workplace is significantly greater than the proportion of men who perceive it to be a major problem.

The values of x such that f(x) = x + 2 and g(x) = 2^x + 1 if f(x = g(x) are x =0 and x = 1

Given that

f(x) = x + 2

g(x) = 2^x + 1

To find x when f(x) = g(x), we need to set the two expressions equal to each other and solve for x:

f(x) = g(x)

x + 2 = 2^x + 1

Subtracting 1 from both sides:

x + 1 = 2^x

We can solve for x by using trial and error or by using numerical methods.

One solution to this equation is x = 1.

To see why, we can plug x = 1 into both sides of the equation:

x + 1 = 2^x

1 + 1 = 2^1

2 = 2

Another solution is x = 0

0 + 1 = 2^0

0 + 1 = 1

1 = 1

Anything on one side of the equals sign in a calculation must equal anything on the other side of the equals sign. So long as we maintain the balance on both sides of the equals symbol, we can do whatever we want to an equation.

We can create a system of equations using the provided values (8, 10) and (9, 12) in order to determine the rule that connects x and y. One approach is as follows:

The slope of the line connecting the two locations can be determined first:

m = (y2 - y1)/(x2 - x1) = (12 - 10)/(9 - 8) = 2/1 = 2

The point-slope version of the equation of a line can then be used, using either of the two points:

We want tο find P(A|B), the prοbability that the subject has the disease given a negative test result.

Bayes' theοrem states that:

P(A|B) = P(B|A) * P(A) / P(B)

where P(B|A) is the probability of a negative test result given that the subject has the disease, P(A) is the prior probability of the subject having the disease, and P(B) is the probability of a negative test result.

From the table, we can calculate:

P(B|A) = 9/96 = 0.09375

P(A) = (87+9)/(87+9+27+312) = 0.235

P(B) = (27+312)/(87+9+27+312) = 0.883

Plugging these values into Bayes' theorem, we get:

P(A|B) = 0.09375 * 0.235 / 0.883 ≈ 0.025

The equation is now in the standard shape of a hyperbola, as per the provided assertion. [(x - h)² / a²] - [(y - k)² / b²] = 1

A curve formed by the junction of a double right-angled cone and a plane that slices one half of the cone. a plane curve produced by a point so mobile that the difference between its distance from two fixed locations is a constant.

To complete the square for the given equation, we will group the x and y terms and complete the square separately for each.

4x² + 24x - 9y² + 18y - 9 = 0

4(x² + 6x) - 9(y² - 2y) = 9

4(x² + 6x + 9 - 9) - 9(y² - 2y + 1 - 1) = 9

4(x + 3)² - 9(y - 1)² = 36

Dividing by 36, we get:

(x + 3)² / 9 - (y - 1)² / 4 = 1

So, the equation is now in the standard form of a hyperbola:

[(x - h)² / a²] - [(y - k)² / b²] = 1

where h and k are the coordinates of the center, a is the distance from the center to the vertices along the x-axis, b is the distance from the center to the vertices along the y-axis, and the slope of the asymptotes is b/a.

Comparing with the standard form, we can see that:

h = -3, k = 1, a = 3, b = 2, and the slope of the asymptotes is b/a = 2/3.

The center is (-3, 1). The hyperbola opens horizontally, and its vertices are located at (-3 + a, 1) and (-3 - a, 1). So, the vertices are (-6, 1) and (0, 1).

The asymptotes are two straight lines passing through the center with a slope of ±(b/a) = ±2/3. So, the equations of the asymptotes are y - 1 = (2/3)(x + 3) and y - 1 = -(2/3)(x + 3), which simplify to y = (2/3)x + 5/3 and y = -(2/3)x + 1/3.

The distance between the center and the foci is c = sqrt(a² + b²) = √(13). The foci are located at (-3 + c, 1) and (-3 - c, 1). So, the foci are approximately (-0.16, 1) and (-5.84, 1).

The graph of the hyperbola looks like two mirrored U-shaped curves, with the vertices being the endpoints of the transverse axis.

The asymptotes intersect at the center and divide the hyperbola into four parts, called branches. The foci are located on the transverse axis, inside the branches.
