Answer:  6 * 24 = 144 ways.

Step-by-step explanation:

Solution:

Given word => DANGER.

The condition is that vowels can't occupy odd places so, we will let them occupy even places.

A total number of arrangements will be = 6 * 24 = 144 ways.

Answer: 6x24 = 144 ways.

If the sample sizes are n1 and n2, the simplest way to compute the degrees of freedom is to use the smaller n1-1 and n2-1. these are two-sample hypothesis testing.

Degrees of freedom

The number of independent data points used to calculate an estimate is referred to as the degree of freedom of the estimate. It's not exactly the same as the sample's sample size. You must deduct 1 from the total number of items in order to obtain the degree of freedom (df) for the estimate. Imagine you were looking for the average weight loss for a low-carb diet. One option is to utilize 100 persons with df = 99 or 4 people with 3 degrees of freedom (4 - 1 = 3).

Two Samples: Degrees of Freedom

You must take into account two "n"s if you have two samples and wish to find a parameter like the mean (sample 1 and sample 2). In the scenario, degrees of freedom are :

Degrees of Freedom (Two Samples): (N1 + N2) – 2

Step-by-step explanation:

The maximum error in the calculated area of the disk is 26.39 cm². The percentage error is 3.73%. (Round your answer to two decimal places.)

The radius of a circular disk is given as 15 cm with a maximum error in measurement of 0.28 cm.

Use differentials to estimate the maximum error in the calculated area of the disk.

We know that the formula for the area of a circle is given by:

A = πr²

where r is the radius of the circle.

Using differentials, we have:

dA = 2πrdr

Substituting the given values:

r = 15 cm and dr = 0.28 cmdA = 2π(15)(0.28)dA ≈ 26.39 cm²

Therefore, the maximum error in the calculated area of the disk is 26.39 cm².

The relative error is given by the formula:

Relative error = (Error in measurement / Actual value) × 100%

The actual value of the area of the disk is given by:

A = π(15)²A = 706.86 cm²

Substituting the values we calculated earlier, we have:

Relative error = (26.39 / 706.86) × 100%

Relative error ≈ 3.73%

Therefore, the relative error is approximately 3.73%.

The percentage error is the same as the relative error, which is 3.73%.

Therefore, the percentage error is 3.73%.

Step-by-step explanation:

1. You first do what’s in the parentheses (in this situation, there are none)

2. Second, exponents (again, there are none)

3. Third, any multiplication or division (whichever comes first) from left to right (-25 x 0 =0)

4. You now have 50+50-0+2+2

5. Fourth, you do addition and subtraction from left to right, 50+50 = 100

6. Now you have 100-0+2+2

7. This gives you the correct answer of 104

Answer:

no solutions

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

equation of blue line is y = x + 2 , in slope- intercept form

with slope m = 1

equation of red line is y = x - 3 , in slope- intercept form

with slope m = 1

• Parallel lines have equal slopes

then the blue and red lines are parallel.

the solution to the system is at the point of intersection of the 2 lines

since the lines are parallel then they do not intersect each other.

thus the system shown has no solution.

Answer:

\(\huge\boxed{43 \textdegree}\)

Step-by-step explanation:

We can use basic angle relationships to find the measure of z.

We know that all angles in a triangle will add up to 180°. Since we already know two out of the 3 angles (47° and 90° - right angles are always 90°) we can add those two up and subtract from 180 to find out the missing angle length.

\(47+90=137\\\\180-137=43\)

Answer:

130° and 310°

Step-by-step explanation:

the bearing of A from B is the measure of the clockwise angle from a north line at B to A

the angle at B and A are same- side interior angles and sum to 180°

angle at B = 180° - 50° = 130°

the bearing of A from B is then 130°

the bearing of B from A is the measure of the clockwise angle from the north line at A to B

the complete angle about A = 360° then clockwise angle from north line at A to B is

360° - 50° = 310°

the bearing of B from A is 310°

By performing subtraction we know that the farmer sold 4.2 kilograms of apples in the market.

One of the four operations used in mathematics, along with addition, multiplication, and division, is subtraction.

Removal of items from a collection is represented by the operation of subtraction.

For instance, in the following image, there are 5 2 peaches, which means that 5 peaches have had 2 removed, leaving a total of 3 peaches.

Subtraction in mathematics is the process of subtracting one integer from another. In other words, the result of subtracting two from five is three. After addition, subtraction is usually the second operation you learn in math class.

So, to find the weight of apples, perform subtraction as follows:

= 6.7 - 2.5

= 4.2 kilograms

Therefore, by performing subtraction we know that the farmer sold 4.2 kilograms of apples in the market.

The width of the dog run is 20 feet.

In the given problem, the length of the dog run is given as 30 feet.

The area of the dog run is also given as 240 square feet.

Using the formula for the area of a rectangle (A = lw), we can solve for the width (w).

Rearranging the formula, we have w = A / l.

Plugging in the values, we get w = 240 / 30 = 8 feet.

Since the width is given as (30 minus x) feet, we can set up an equation:

30 - x = 8. Solving for x, we find x = 22.

Therefore, the width of the dog run is 20 feet (30 - 22 = 8).

In this problem, the length and width of the dog run are defined by the dimensions of the fence being built around it.

The area of the dog run is given as 240 square feet.

By using the formula for the area of a rectangle, we can solve for the width. We are also given that the length is 30 feet.

Setting up an equation with the given width (30 minus x) and solving for x, we find that x is equal to 22.

This means that the width of the dog run is 8 feet. The main answer to the problem is that the width of the dog run is 20 feet (30 - 22 = 8).

Diameter of sphere = 18 cm

Step-by-step explanation:

     Diameter = 18 cm

                  r = 18÷ 2 = 9 cm

                 h = 12 cm

\(\sf \boxed{\bf Volume \ of \ cylinder = \pi r^2h}\)

                                    = π * 9 * 9 * 12 cm³

  \(\sf \boxed{\text{\bf Volume of sphere = $\dfrac{4}{3} \pi r^3$}}\)

Solid cylinder is melted and turned into a solid sphere.

Volume of sphere = volume of cylinder

 \(\sf \dfrac{4}{3}\pi r^3 = \pi *9*9*12\)

      \(\sf r^{3}= \dfrac{\pi *9*9*12*3}{4*\pi }\\\\ r^{3}=9 * 9 *3 *3\\\\\\r = \sqrt[3]{9*9*9}\\\\ r = 9 \ cm\\\\diameter = 9*2\\\\\boxed{diameter \ of \ sphere = 18 \ cm}\)

Answer:

\(a_{n}\) = 6n

Step-by-step explanation:

there is a common difference between consecutive terms, that is

12 - 6 = 18 - 12 = 6

this indicates the sequence is arithmetic with nth term

\(a_{n}\) = a₁ + d(n - 1)

where a₁ is the first term and d the common difference

here a₁ = 6 and d = 6 , then

\(a_{n}\) = 6 + 6(n - 1) = 6 + 6n - 6 = 6n

According to the concept of algebraic expression and arithmetic, the correct answers are A) Number of adults = N - 25. B) Number of adults when N = 124: 124 - 25 = 99

A) Let's denote the number of children as N. Since there are 25 fewer adults than children, the number of adults can be expressed as N - 25.

B) If there are 124 children, we substitute N with 124 in the expression from part A. Thus, the number of adults would be 124 - 25 = 99.

To arrive at these answers, we used the given information that there are "N" children and 25 fewer adults than children. By substituting the value of N, we determined the number of adults in terms of N and then calculated the specific number of adults when N is equal to 124.

Note: The given question is incomplete. The complete question is:

Some adults and children are watching a musical. there are 'N' number of children. There are 25 fewer adults than children.
