Step-by-step explanation:

The markup rate of a product or service refers to how higher the selling price is than the total production cost. In this case, this company doesn't produce the bikes, instead it purchases them from a wholesaler, distributor or even the factory, and then resells them in order to make a profit.

E.g. Beach Bicycles purchases two-seater bikes at $200 each, and then it will resell them to their customers at 1.68 x $200 = $336. The total markup in this example is $136, which represents $136/$200 = 68% of the purchase price.

The correct answer is - Two-paragraph proof.

A paragraph proof is only a two-column proof that is written in sentences. However, since it is easier to leave steps out when writing a paragraph proof.

The solution to the given problem does not need any columns and can be proved in just sentences. Therefore, it is a two-paragraph proof.

Step-by-step explanation:

The equation which is results from applying the secant and tangent segment theorem to the provided figure is,

\(x(2x +4) = (x +2)^2\)

The secant-tangent theorem tells the relation of the line segment made by a tangent and the secant lines with the connected circle.

According to this theorem, if the tangent and secant segments are drawn from an exterior point, then the square of this tangent segment is equal to the product of the secant segment and the line segment from that exterior point.

The image of the given problem is attached below. In the attached image, the tangent is given as,

\(T=x+2\)

The secant is shown in the image has the value,

\(S=x+x+4\\S=2x+4\)

Now according to the secant tangent theorem,

\(x(2x +4) = (x +2)^2\)

Hence, the equation which is results from applying the secant and tangent segment theorem to the provided figure is,

\(x(2x +4) = (x +2)^2\)

In the figure,  an angle that is adjacent to angle BEC is angle BEA.

What are the adjacent angles ?

When the apex and side of the two angles are the same, the two angles are referred to as adjacent angles.

The vertex of an angle is the place where the rays come to an end and create the sides of the angle. When two adjacent angles share a vertex and a side, they can be either complimentary or supplementary angles.

The probability of not succeeding next attempt is 7/16

Step-by-step explanation:

Here in this question, we are asked to write the probability of not succeeding in the next attempt given that he attempted 9 success out of 16 trials.

To calculate this probability of not succeeding, we need to get it from the number of unsuccessful throws.

Thus, if 9 throws are successful out of 16, then the number of unsuccessful throws will be 16-9 = 7

So the probability of not succeeding on next attempt will be 7/16

What does a quadratic function mean?

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. In other words, a "polynomial function of degree 2" is a quadratic function.

The formula for the solution of a quadratic equation \(ax^{2} +bx+c=0\) is

\(x=\frac{-b+-\sqrt[2]{b^{2}-4ac } }{2a}\).

So, the solution for the equation \(2x^{2} +x-4=0\) is

\(x=\frac{-1+-\sqrt[2]{1^{2}-4*2*(-4) } }{2*2}\\x=\frac{-1+-\sqrt[2]{1+32 } }{4}\\x=\frac{-1+-\sqrt{33} }{4}\)

Answer:

A 95​% confidence interval for the proportion of students who eat cauliflower on​ Jane's campus is [0.012, 0.270].

Step-by-step explanation:

We are given that Jane wants to estimate the proportion of students on her campus who eat cauliflower. After surveying 24 ​students, she finds 2 who eat cauliflower.

Firstly, the pivotal quantity for finding the confidence interval for the population proportion is given by;

                              P.Q.  =  \(\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }\)  ~ N(0,1)

where, \(\hat p\) = sample proportion of students who eat cauliflower

           n = sample of students

           p = population proportion of students who eat cauliflower

Here for constructing a 95% confidence interval we have used a One-sample z-test for proportions.

So, 95% confidence interval for the population proportion, p is ;

P(-1.96 < N(0,1) < 1.96) = 0.95  {As the critical value of z at 2.5% level

                                                   of significance are -1.96 & 1.96}  

P(-1.96 < \(\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }\) < 1.96) = 0.95

P( \(-1.96 \times {\sqrt{\frac{\hat p(1-\hat p)}{n} } }\) < \({\hat p-p}\) < \(1.96 \times {\sqrt{\frac{\hat p(1-\hat p)}{n} } }\) ) = 0.95

P( \(\hat p-1.96 \times {\sqrt{\frac{\hat p(1-\hat p)}{n} } }\) < p < \(\hat p+1.96 \times {\sqrt{\frac{\hat p(1-\hat p)}{n} } }\) ) = 0.95

Now, in Agresti and​ Coull's method; the sample size and the sample proportion is calculated as;

\(n = n + Z^{2}__(\frac{_\alpha}{2})\)

n = \(24 + 1.96^{2}\) = 27.842

\(\hat p = \frac{x+\frac{Z^{2}__(\frac{\alpha}{2}_) }{2} }{n}\) = \(\hat p = \frac{2+\frac{1.96^{2} }{2} }{27.842}\) = 0.141

95% confidence interval for p = [ \(\hat p-1.96 \times {\sqrt{\frac{\hat p(1-\hat p)}{n} } }\) , \(\hat p+1.96 \times {\sqrt{\frac{\hat p(1-\hat p)}{n} } }\) ]

 = [ \(0.141 -1.96 \times {\sqrt{\frac{0.141(1-0.141)}{27.842} } }\) , \(0.141 +1.96 \times {\sqrt{\frac{0.141(1-0.141)}{27.842} } }\) ]

 = [0.012, 0.270]

Therefore, a 95​% confidence interval for the proportion of students who eat cauliflower on​ Jane's campus [0.012, 0.270].

The interpretation of the above confidence interval is that we are 95​% confident that the proportion of students who eat cauliflower on​ Jane's campus is between 0.012 and 0.270.

Answer:

c

Step-by-step explanation:

To find the value of k for which the constant function \(X(t) = k\) is a solution of the differential equation \(7t^2 \frac{dx}{dt} + 8x + 8 = 0\), the value of k that satisfies the differential equation \(7t^2 \frac{dx}{dt} + 8x + 8 = 0\) when \(X(t) = k\) is a constant function is k = -1.

We replace "X(t) = k" into the differential equation "7t2 fracdxdt" + 8x + 8 = 0" to obtain "7t2 fracdxdt(k) + 8k + 8 = 0." The derivative of X(t) = k with respect to t is 0 since it is a constant function. As a result, the word "(7t2 frac dt(k)" becomes zero, leaving us with the expression "(8k + 8 = 0)".

In order to find k in this equation, we first divide both sides by 8 to get (k = -1), then subtract 8 from both sides to get (8k = -8). The constant function "X(t) = k" is a solution of the differential equation "7t2 fracdxdt+8x+8 = 0" for the value of k such that k = -1.

In conclusion, the value of k that, when X(t) = k), satisfies the differential equation (7t2 frac dx dt + 8x + 8 = 0),

the inequality to determine if a child's height satisfies the regulation is:

30in < h < 50 in.

Here we know that the allowed height of the child can be any value between 30 inches and 50 inches (not included, so we need to use the symbols > and <)

So, if we define h as the height, then h must be larger than 30 inches, so we can wrte:

h > 30 in

And h must be smaller than 50 inches, then:

h < 50 in.

If we write these two inequalities as one, we get:

30in < h < 50 in.

That is the inequality to determine if a child's height satisfies the regulation.

The probability mass function (PMF) of a random variable X can be derived from its moment-generating function (MGF). In this case, the MGF of X is given as (0.3 + 0.7e^2t)^8.

To find the PMF of X, we can use the MGF to determine the probabilities associated with each possible value of X. The PMF represents the discrete probability distribution of X.

In this case, the MGF is (0.3 + 0.7e^2t)^8. By expanding and simplifying this expression, we can determine the coefficients of the terms corresponding to each value of X. These coefficients represent the probabilities associated with those values.

Unfortunately, without further information or context, it is not possible to provide the explicit form of the PMF for X in this scenario. Additional details or equations would be required to determine the specific probabilities associated with each value of X.

Let's translate the argument into symbolic form using the following symbols:

B: Brazil has a huge foreign debt.

A: Argentina has a huge foreign debt.

The argument can be represented as follows:

B → (B ∨ A)

To determine the validity of the argument, we can construct a truth table for the expression (B → (B ∨ A)). The truth table will include all possible combinations of truth values for B and A, and we will evaluate the truth value of the entire expression for each combination.

The truth table for the argument is as follows:

B A B ∨ A B → (B ∨ A)

T T T T

T F T T

F T T T

F F F T

As we can see from the truth table, regardless of the truth values of B and A, the expression B → (B ∨ A) always evaluates to true. Therefore, the argument is valid because the conclusion is always true when the premise is true.
