It will take approximately 3.33 hours for both persons working together to complete the job.

What is distance?

Distance is the measure of how far apart two objects or locations are from each other. It is usually measured in units such as meters, kilometers, miles, or feet.

To solve this problem, we can use the following formula:

1 / T = 1 / t1 + 1 / t2

Where T is the time it takes for both persons working together to complete the job, t1 is the time it takes for the first person to complete the job alone, and t2 is the time it takes for the second person to complete the job alone.

Plugging in the given values, we get:

1 / T = 1 / 5 + 1 / 10

Simplifying the right side, we get:

1 / T = 3 / 10

Multiplying both sides by 10T, we get:

10 = 3T

Dividing both sides by 3, we get:

T = 10 / 3 = 3.33 hours

Therefore, it will take approximately 3.33 hours for both persons working together to complete the job.

If the representative fraction scale is 1:48000, then the verbal scale from inches to feet is  1 inch represents 0.00025 feet.

We have to find the verbal (written) scale from inches to feet that represents a map with a representative-fraction (RF) scale of 1:48,000,

We use the formula:

⇒ Verbal scale = RF × Inches per foot,

We know that the RF scale is 1:48,000, which means that one unit on the map represents 48,000 units in the real world.

There are 12 inches in a foot,

So, we can convert the verbal scale to inches-per-foot by dividing by 12:

⇒ Inches per foot = (Verbal scale)/(12),

⇒ Inches per foot = (1/48000) × (12/1) = 0.00025

Therefore, the verbal scale from inches to feet is : 1 inch represents 0.00025 feet.

To check if Line L1 and Line L2 are parallel, we need to check if their slopes are equal.

Given L1 is y=2x+1

The slope of L1 is the coefficient of x, which is 2.

since L1 is in the form of y=mx+c where m is the slope

Given  L2 is 4y-8x+1=0

To find the slope of L2, we need to rearrange it to slope-intercept form

y = mx + b, where m is the slope and b is the y-intercept.

4y - 8x + 1 = 0

4y = 8x - 1

y = 2x - 1/4

Now the above equation is in the form of y=mx+c

The slope of L2 is also 2.

Since both lines have the same slope, we can conclude that they are parallel. Therefore, we can say that Line L1 and Line L2 are parallel.

To find the circle and radius of equation x2 + y2 +12x +6y +20=0, we need to complete the square for both x and y terms.

First, we can simplify the equation by rearranging the constant term to the right-hand side:

x^2 + y^2 + 12x + 6y = -20

Next, we can complete the square for the x-terms by adding (12/2)^2 = 36 to both sides of the equation:

x^2 + 12x + 36 + y^2 + 6y = -20 + 36

Simplifying further:

(x + 6)^2 + (y + 3)^2 = 13

This is now in the standard form of a circle: (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center of the circle and r is the radius.

So the center of the circle is (-6, -3) and the radius is the square root of 13. Therefore, the equation x^2 + y^2 + 12x + 6y + 20 = 0 represents a circle with center (-6, -3) and radius sqrt(13).

The 99% confidence interval for the mean GPA of all accounting students at this university is approximately (3.12272, 3.27728). This means we are 99% confident that the true mean GPA of all accounting students at this university falls between 3.12272 and 3.27728.

To construct the 99% confidence interval for the mean GPA of all accounting students at this university, follow these steps:
Identify the sample size, mean, and standard deviation: In this case, the sample size (n) is 25, the mean (x) is 3.20, and the standard deviation (s) is 0.15.
Determine the confidence level: The problem states we need a 99% confidence interval, so the confidence level is 99%.
Find the critical value (z-score) for the confidence level: For a 99% confidence interval, the critical value (z) is 2.576 (you can find this value in a standard z-score table).
Calculate the standard error (SE) of the sample mean: SE = s / √n = 0.15 / √25 = 0.15 / 5 = 0.03.
Calculate the margin of error (ME): ME = z * SE = 2.576 * 0.03 = 0.07728.
Find the lower and upper limits of the confidence interval:
- Lower limit = x - ME = 3.20 - 0.07728 = 3.12272.
- Upper limit = x + ME = 3.20 + 0.07728 = 3.27728.

Answer: 3,64

Step-by-step explanation:

The angle A and D will be equal by the help of side angle side theorm.

What is side angle side theorem?

The Side-Angle-Side (SAS) theorem is a concept in geometry that states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent. In other words, if two triangles have the same length of two sides and the angle between those sides is also the same, then the two triangles are identical in shape and size. The SAS theorem is one of the several postulates that can be used to prove congruence between two triangles.

The angle ABC is equal to angle DBE by vertical opposite angle

AC  is equal to DE

and CB is equal to EB

therefore angle A and angle D

Congruent triangles are triangles that have the same shape and size. When two triangles are congruent, it means that they have the same angles and side lengths. In other words, they are identical in every way, and one can be superimposed onto the other by rotating, reflecting or translating.

There are several ways to prove that two triangles are congruent, including:

Side-Side-Side (SSS) theorem: if all three sides of one triangle are congruent to the corresponding sides of another triangle, then the two triangles are congruent.

Side-Angle-Side (SAS) theorem: if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.

Angle-Side-Angle (ASA) theorem: if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.

The length of arc TU is approximately 0.3935 cm.

Calculation of circle ?

To find the length of arc TU, we first need to determine the measure of angle TAU. Since TV is a diameter, we know that angle TSV is a right angle (90 degrees). Since S is the midpoint of TV, angle TSU is half of angle TSV, which means angle TSU is 45 degrees (90/2 = 45). Therefore, angle TAU is the complement of angle TSU, which is 90 - 45 = 45 degrees.

Next, we need to use the formula for the length of an arc of a circle, which is L = rθ, where L is the length of the arc, r is the radius of the circle, and θ is the measure of the central angle of the arc in radians. Since we have the measure of the central angle in degrees, we need to convert it to radians by multiplying by π/180.

The radius of the circle is half the diameter, which is 0.5 cm. Therefore, we have:

L = rθ

L = 0.5 × (45 × π/180)

L = 0.5 × (0.25π)

L = 0.125π

To get a numerical value, we can use an approximation of π, such as 3.14. Therefore, the length of arc TU is approximately:

L ≈ 0.125π ≈ 0.125 × 3.14 ≈ 0.3935 cm

So the length of arc TU is approximately 0.3935 cm.

The formula of a circle relates its radius, diameter, and circumference.

The diameter of a circle is the distance across the circle passing through its center, and is given by:

D = 2r

where r is the radius of the circle.

The circumference of a circle is the distance around its outer edge, and is given by:

C = 2πr

where r is the radius of the circle, and π (pi) is a mathematical constant approximately equal to 3.14159.

The area of a circle is the region enclosed by the circle, and is given by:

A = πr²

where r is the radius of the circle, and π (pi) is a mathematical constant approximately equal to 3.14159.

These formulas can be used to solve various problems related to circles, such as finding the area, circumference, radius, or diameter of a circle, given one or more of these values.

That g(x) is a vertical stretch of f(x) by a factor of 3, followed by a vertical shift of 3 units upward.

The function g(x) = 3[tex]2^{x}[/tex] is a transformation of the parent function f(x) = [tex]2^{x}[/tex]. Specifically, g(x) is obtained by first stretching f(x) vertically by a factor of 3, and then shifting it upward by some amount.    

To understand this transformation more clearly, consider the effect of changing the value of x on both functions. For the parent function f(x) = [tex]2^{x}[/tex], increasing x by 1 corresponds to multiplying the output (y-value) by 2. For example, if we evaluate f(x) at x=0, we get f(0) = [tex]2^{0}[/tex] = 1, and if we evaluate it at x=1, we get f(1) =[tex]2^{1}[/tex]  = 2, which is double the value of f(0).

Now, let's consider the function g(x) =3[tex]2^{x}[/tex] . When we evaluate g(x) at x=0, we get g(0) = 3[tex](2)^{0}[/tex] = 3, which is triple the value of f(0). Similarly, when we evaluate g(x) at x=1, we get g(1) = 3[tex](2)^{1}[/tex] = 6, which is triple the value of f(1). This shows that g(x) is a vertical stretch of f(x) by a factor of 3.

Finally, notice that the function g(x) has the same shape as f(x), but is shifted upward by an amount of 3 units. We can see this by comparing the graphs of the two functions. The graph of f(x) starts at the point (0,1) and increases rapidly as x gets larger. The graph of g(x) starts at the point (0,3) and increases at the same rate as f(x). This shows that g(x) is a vertical stretch of f(x) by a factor of 3, followed by a vertical shift of 3 units upward.

In the given problem, we find that Luis is wrong because the probability of getting a Yahtzee in one roll of the dice is 1/6^5.

Luis is wrong because the probability of getting a Yahtzee in one roll of the dice is 1/6^5. This is approximately 0.00077 or 0.077%.

A Yahtzee is a combination of five dice with the same number on each dice. The probability of rolling any specific combination of five dice is 1/6^5 and this is because each dice has a 1/6 probability of showing the required number.

The probability of rolling a Yahtzee in one roll of the dice is 6 times the probability of rolling any specific combination, which is 6 x 1/6^5 or 1/6^4  since there are only six possible combinations of a Yahtzee (one for each number on the dice).
