Answer:

7

Step-by-step explanation:

The two lengths (4x-7 and x+14) are the same. This is because if we look at the big trapezoid as a whole, the ratio of the three segments on the side (4, 4, 4) is the same as the ratio of the three lengths on the other side. Therefore the ratio of the two lengths would be the same as well, 1:1. (btw the photo that I attached is what I mean by the two sides). So, we can form the equation: 4x-7 = x+14. The steps to solve the problem:

4x-7 = x+14

3x=21

x=7

The value of x is 7!

Gerry's beginning basis in the S corporation is $20,545.

To calculate Gerry's beginning basis in the S corporation, we need to consider the cost of the assets transferred and the additional expenses incurred for the conversion.

The cost of the assets transferred is given as $19,570. This represents the original cost of the assets when Gerry acquired them.

The adjusted basis of the assets is stated as $9,600. The adjusted basis takes into account any adjustments made to the original cost, such as depreciation or other deductions.

To calculate the beginning basis in the S corporation, we add the cost of the assets transferred ($19,570) to the adjusted basis ($9,600). This gives us a total of $29,170.

In addition to the assets, Gerry incurred an additional expense of $975 for the conversion to an S corporation. We include this amount in the calculation of the beginning basis.

Therefore, Gerry's beginning basis in the S corporation is $29,170 + $975 = $20,545.

This beginning basis is important for determining Gerry's tax consequences and future deductions within the S corporation structure.

Answer: 6√6

Step-by-step explanation: When an angle is 45 degrees in a triangle it is actually half a square (I know right!!!), so, therefore, the other side length will also be 6, and then using the Pythagorean theorem we get the hypotenuse to be 6√2. Now, when an angle is 60 degrees in a triangle it is actually half an equilateral triangle (I know right!!!), so, therefore, the other side length will be double the length, 12√2, and using the Pythagorean theorem we get the side length x to be 6√6!

Number of economy seats are 181

An equation between two variables that gives a straight line when plotted on a graph

Consider,

Number of economy seats =x

Number of First class seats =y

There are 209  total seats on the airplane

Then,

x + y=209

Difference between the number of economy and first class seats is 153

x - y=153

Solve both the equation

x + y=209

x = 209-y

Substitute the value of x in second equation

(209-y) - y=153

2y=209-153=56

y=28

Then

x + y=209

x + 28=209

x=209-28

x=181

Hence, the number of economy seats are 181

Answer:

192

Step-by-step explanation:

You have to find 20% of 240.

So write 20% as 20 over 240 in fraction form.

[tex]\frac{20}{240}[/tex]

Since, finding the fraction of a number is same as multiplying the fraction with the number, we have

[tex]\frac{20}{100}[/tex] of 240 = [tex]\frac{20}{100}[/tex] × 240

Therefore, the answer is 48

If you are using a calculator, simply enter 20÷100×240 which will give you 48 as the answer.

Now since it  wants to know how much you paid for the goods you do 240-48=192

So since a company is selling goods with a 20% profit

That means they bought it from somewhere else

Because they had to be manufactured

It wants how much the company paid the company that manufactured the goods

Answer:

11.2 minutes

Step-by-step explanation:

If the element decreases by 6.1, every minute, it means that the mass lost every minute = 0.061 x 700g = 42.7g

The mass remaining after a minute = 657.30g

The equation that can be used to solve this question is :

700 - 42.7m = 220

m = minutes

Collect like terms

700 - 220 = 42.7m

480 = 42.7m

divide both sides of the equation by 42.7

m = 11.241218 minutes

the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero

SOO just remember to divide the diameter by two to get the radius. If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of the circle is 3.5 feet.

Step-by-step explanation:

The analysis involves calculating probabilities, bounding the probabilities based on worst-case scenarios, and considering the implications of the Chernoff bound to demonstrate the existence of tournaments without a certain number of winners.

In a tournament between N teams, where each team plays each other, the concept of a k-winner is introduced. A team i is considered a k-winner if there is a group of k teams that were each beaten by team i. The probability that a given team i is a k-winner can be calculated when the results of each game are decided by a fair coin flip. This probability depends on the number of teams and the specific value of k.

Using this probability for a given team, we can bound the probability that there exists a k-winner in a tournament of size N. This bound takes into account the probabilities of individual teams being k-winners and considers the worst-case scenario.

For a specific value of N, such as N = 100, we can determine the smallest k for which the probability of having k-winners is less than 1. This can be done by evaluating the probabilities for different values of k until the desired condition is met.

When N = 100 and k is determined as in the previous step, it can be argued that there exist possible tournaments with no k-winners. This can be demonstrated by constructing specific scenarios or by analyzing the probabilities of different outcomes.

Using the Chernoff bound, it can be shown that for a value a greater than 1/2, the probability of having any oN-winners (where oN is an arbitrary constant) goes to 0 as N approaches infinity. This conclusion implies that there exist tournaments without N-winners for sufficiently large values of N.

To find the first five terms of a sequence defined by a recurrence relation and initial conditions, we apply the relation repeatedly. Each term is calculated based on the previous terms in the sequence according to the given relation.

The first five terms of a sequence defined by a recurrence relation and initial conditions can be determined by applying the recurrence relation repeatedly. Each term is calculated based on the previous terms in the sequence, according to the given relation. Here are the first five terms for each recurrence relation:

1. Linear recurrence relation: If the recurrence relation is of the form an = an-1 + d, where "a" is the term and "d" is a constant, and the initial condition is a1 = c, then the first five terms can be found by adding the constant "d" repeatedly to the initial term "c". For example, if c = 2 and d = 3, the first five terms would be 2, 5, 8, 11, 14.

2. Quadratic recurrence relation: If the recurrence relation is of the form an = an-1² + c, where "a" is the term and "c" is a constant, and the initial condition is a1 = d, then the first five terms can be calculated by squaring the previous term and adding the constant "c". For instance, if d = 1 and c = 2, the first five terms would be 1, 3, 11, 123, 15187.

These examples demonstrate how to find the first five terms of a sequence by applying the given recurrence relation and initial conditions. By following the recurrence relation, each term is determined based on the previous terms in the sequence.

The solution of the integral (1/6)ln|9x²+1| +(1/3)arctan (3x) +(1/6)arctan((3x)²)- (1/18)(3x)²/(9x²+1) + (1/90)(3x)⁴/(9x²+1) + C.

We have the following integral to solve.∫ [(1+cos(arctan (3x))+(arctan (3x))⁵)/(1+9x²2)]dx

Let's begin by using the substitution u = arctan(3x).

We need to convert this integral into a U-form. By substituting the above expression, we have the following new expression.

∫ [(1+cos u)+u⁵]/[1+9(3tanu)²] *(1/3) du=∫ [(1+cos u)+u⁵]/(9tan²u+1) *(1/3) du

Let's now consider the numerator.

We have 1+cosu+u⁵ in the numerator. Let's break down the integral into 3 parts. The first part is ∫(1)/(9tan²u+1) *(1/3) du.

We can convert the denominator to a perfect square of the form 3²tan²u+1 which simplifies to (3tanu+1)(3tanu-1)+2.

Let's now factorize

= ∫(1)/(9tan²u+1) *(1/3) du

=∫(1)/[(3tanu+1)(3tanu-1)+2] *(1/3) du

Now let's perform partial fraction decomposition. We have 1/[(3tanu+1)(3tanu-1)+2] which we can write as

= A/(3tanu+1)+B/(3tanu-1)+C/(3tan²u+1) where A, B, and C are constants to be determined.

We now have 1= A(3tanu-1)(3tan²u+1)+ B(3tanu+1)(3tan²u+1)+ C(3tanu+1)(3tanu-1).

Let's now set up the system of equations.

The first equation is

1= A(3tanu-1)(3tan²u+1)+ B(3tanu+1)(3tan²u+1)+ C(3tanu+1)(3tanu-1)

Putting u=0, we get

A = 1/4

Putting u =pi/3, we get

B=1/4 Putting

u = arctan(1/√(3)), we get C=1/2. Now that we have A, B, and C, let's substitute them back to our integral.

We have

= ∫(1)/[(3tanu+1)(3tanu-1)+2] *(1/3) du

= (1/4)∫(1)/(3tanu+1) du + (1/4)∫(1)/(3tanu-1) du +(1/2)∫(1)/(3tan²u+1) du

Let's now solve the integral and simplify.

= ∫(1)/(3tanu+1) du

= (1/6)ln|3tanu+1|- (1/6)ln|3tanu-1|+ (1/3)arctan (3tanu).

Similarly,

= ∫(1)/(3tanu-1) du

= (-1/6)ln|3tanu+1|+ (1/6)ln|3tanu-1|+ (1/3)arctan (3tanu).

The third integral we can solve by substitution

v = √(3)tanu.

We then get

=  ∫(1)/(3tan²u+1) du= (1/√(3))∫(1)/(v²+3) dv

= (1/sqrt(3))arctan(v/√(3))

= (1/√(3))arctan((√(3)tanu)/√(3)).

We can now put back all the values to get the solution.

= ∫ [(1+cos(arctan (3x))+(arctan (3x))⁵)/(1+9x²)]dx

= (1/3)∫ [(1+cos u)+u⁵]/(9tan²u+1) du

=(1/3)[(1/4)(ln|3tanu+1|- ln|3tanu-1|+ 2arctan (3tanu))+(1/4)(-ln|3tanu+1|+ ln|3tanu-1|+ 2arctan (3tanu))+(1/2)(1/√(3))(arctan((sqrt(3)tanu)/√(3)))]+ C

We can simplify the above expression to get

=- ∫ [(1+cos(arctan (3x))+(arctan (3x))^5)/(1+9x²)]dx

= (1/6)ln|9x²+1| +(1/3)arctan (3x) +(1/6)arctan((3x)²)- (1/18)(3x)²/(9x²+1) + (1/90)(3x)⁴/(9x²+1) + C

The appropriate test to investigate whether the proportion of students failing the comprehensive statistics final has decreased with the shift to online instruction is the z test for two proportions.

Explanation:

The z test for two proportions is used when we want to compare two proportions or percentages from different populations or groups. In this case, we want to compare the proportion of students who fail the statistics final before and after the instruction moved online.

To conduct the z test for two proportions, we follow these steps:

1. Define the null hypothesis (H₀) and alternative hypothesis (H₁). In this case, the null hypothesis would be that the proportion of students failing the final is the same before and after the instruction moved online, while the alternative hypothesis would be that the proportion has decreased after the shift to online instruction.

2. Collect data on the number of students who fail the statistics final before and after the shift to online instruction.

3. Calculate the sample proportions for each group. Let's denote the proportion before the shift as p₁ and after the shift as p₂.

4. Calculate the standard error (SE) of the difference between two proportions using the formula:

SE = sqrt((p₁ * (1 - p₁) / n₁) + (p₂ * (1 - p₂) / n₂))

where n₁ and n₂ are the sample sizes for the two groups.

5. Calculate the test statistic (z) using the formula:

z = (p₁ - p₂) / SE

6. Determine the critical value for the desired significance level (e.g., 0.05) and compare it to the calculated test statistic. If the calculated test statistic falls within the critical region, we reject the null hypothesis; otherwise, we fail to reject the null hypothesis.

7. Interpret the results and draw conclusions about whether there is sufficient evidence to support the claim that the proportion of students failing the statistics final has decreased after the shift to online instruction.
