Answer: 0.81 or 81%

Step-by-step explanation:

     We are looking for the probability that the customer ordered a hot drink if they ordered a large one. This means that our whole is 27, since 22 Hot Large + 5 Cold Large = 27 total large drinks.

     To find the probability, we will divide the total number of wanted outcomes by the total number of possible outcomes.

\(\displaystyle \frac{\text{wanted outcomes}}{\text{possible outcomes}} =\frac{\text{hot large drink}}{\text{large drink}} =\frac{22}{27} =0.81\text{ or } 81\%\)

Step-by-step explanation:

Usando proporciones, hay que con 200 pesos mx se pueden comprar 0.0645 yenes.

Una proporción es una fracción de la cantidad total, y puede ser encontrada por intermedio de una regla de tres.

En este problema, hay que un yene cuesta $0.17, enquanto $1 = 3100 pesos. Por eso, cada yene es equivalente a 3100 pesos.

Por eso, la regla de tres es:

1 yene - 3100 pesos

x yenes - 200 pesos

Aplicando multiplicación cruzada:

\(3100x = 200\)

\(x = \frac{200}{3100}\)

\(x = 0.0645\)

Con 200 pesos mx se pueden comprar 0.0645 yenes.

The expected gain or loss for each participant is -$0.50, which means that on average, each participant can expect to lose 50 cents for every raffle ticket purchased.

To find the expected gain or loss for each participant, we need to calculate the expected value of the raffle ticket.

The probability of winning the first prize of $100 is 1/500, the probability of winning the second prize of $50 is also 1/500, and the probability of winning the third prize of $10 is 1/500. The probability of not winning any prize is (500-3)/500 = 497/500.

The expected value of the raffle ticket can be calculated as:

(expected value of first prize) + (expected value of second prize) + (expected value of third prize) + (expected value of no prize)

= (1/500)($100) + (1/500)($50) + (1/500)($10) + (497/500)($0)

= $0.50

Therefore, the expected gain or loss for each participant is -$0.50, which means that on average, each participant can expect to lose 50 cents for every raffle ticket purchased.

Our assumption is false

We can prove this statement by contradiction. Suppose a > b and c > 0 but ac < bc.

Since a > b, then a - b > 0. Multiplying both sides by c > 0 gives (a - b)c > 0.

We can then add bc to both sides to get (a - b)c + bc > bc.

Since we assumed that ac < bc, then (a - b)c < 0, and thus (a - b)c + bc < bc, which contradicts the previous result.

Therefore, our assumption is false, and we can conclude that for a, b, and c ∈ Z, a > b and c > 0 =⇒ ac ≥ bc.

(a) To find the derivative of the given function, we need to use the product rule of differentiation first, followed by the chain rule.

Using the product rule, we get;` f(x) = ((3/4)x^4+ex^2+π)(x^(3/2)+2/x)`

We can also write this as;` f(x) = u(x) * v(x)`

where u(x) = (3/4)x^4+ex^2+πand v(x) = x^(3/2)+2/x

Now, using the product rule of differentiation, we get;` f'(x) = u'(x)v(x) + v'(x)u(x)`

where u'(x) and v'(x) are the derivatives of u(x) and v(x) respectively.

We have; u'(x) = 3x^3 + 2ex and v'(x) = (3/2)x^(1/2) - 2/x^2

Thus,` f'(x) = (3x^3 + 2ex)(x^(3/2) + 2/x) + ((3/2)x^(1/2) - 2/x^2)((3/4)x^4 + ex^2 + π)`

Now, simplifying the above expression, we get;` f'(x) = (3/2)x^5 + 2ex^2 + 3πx^(1/2) + 2/x^2 + 6x^(3/2) - 2ex/x^2`

We can further simplify this by combining the like terms to get;` f'(x) = (3/2)x^5 + 2ex^2 + 3πx^(1/2) + 6x^(3/2) + (2/x^2 - 2ex/x^2)

We can simplify the last two terms by taking the common denominator, and get;` nf'(x) = (3/2)x^5 + 2ex^2 + 3πx^(1/2) + 6x^(3/2) + 2(x - e)/(x^2)`

Thus, the required derivative of the function `f(x) = ((3/4)x^4+ex^2+π)(x^(3/2)+2/x)` is `(3/2)x^5 + 2ex^2 + 3πx^(1/2) + 6x^(3/2) + 2(x - e)/(x^2)`

(b) To find the derivative of the given function, we can use the quotient rule of differentiation.

Using the quotient rule, we get;` f(x) = (3xe^X)/(X^3-1)`

We can also write this as;` f(x) = u(x) / v(x)`where u(x) = 3xe^Xand v(x) = X^3 - 1

Now, using the quotient rule of differentiation,

we get;` f'(x) = (u'(x)v(x) - v'(x)u(x)) / (v(x))^2`

where u'(x) and v'(x) are the derivatives of u(x) and v(x) respectively.

We have; u'(x) = 3e^x + 3xe^xandv'(x) = 3x^2Thus,`f'(x) = ((3e^x + 3xe^x)(X^3 - 1) - 3x^2(3xe^x)) / (X^3 - 1)^2`

Simplifying the above expression, we get;` f'(x) = (3e^x(X^3 - 1) - 9x^2e^x) / (X^3 - 1)^2`

Thus, the required derivative of the function `f(x) = (3xe^X)/(X^3-1)` is `(3e^x(X^3 - 1) - 9x^2e^x) / (X^3 - 1)^2`.

The ratio c:g:t in its simplest form is 10/3 : 5 : 4.

The ratio of c:g is 2:3 and the ratio of g:t is 5:4.

To write the ratio c:g:t in the simplest form, we need to express c,g and t in terms of a common value and simplify.

Let's begin;Let g be a common value between the ratios c:g and g:t. We can express c and t in terms of g as;

The ratio of c:g is 2:3. That means c is 2/3 of g.The ratio of g:t is 5:4.

That means t is 4/5 of g.We can now express the ratio c:g:t in terms of g, as;

c:g:t = 2/3 : 1 : 4/5

Multiplying by 15 (the LCM of 3 and 5) to get rid of the fractions, we have;

c:g:t = 10 : 15 : 12

Simplifying, we can divide each term by 3 to get the simplest form of the ratio;c:g:t = 10/3 : 5 : 4

Therefore, the ratio c:g:t in its simplest form is 10/3 : 5 : 4.

We may build up a proportion and solve for the scale model radius of Neptune using the ratio between the radii of the two planets and the known scale model radius of the Earth. The scale model of Neptune that is produced has a radius of around 9.7 cm.

We may take advantage of the fact that the ratio between the two planets' radii and the ratio between their respective scale model radii is the same. Let's name the Neptune scale model radius "r" Then, we may set up the ratio shown below:

Neptune's radius is equal to the product of Earth's radius and its scale model.

With the provided values, we may simplify and obtain:

24620 km / 6370 km equals 2.5 cm / r

We obtain the following when solving for "r":

r = (24620 km * 2.5 cm) / (6370 km)

r ≈ 9.7 cm

Therefore, a scale model of Neptune would have to be drawn with a radius of approximately 9.7 cm.

The result of an average of more than 100% in a survey of tenants on cleaning chores in shared apartments is likely due to social desirability bias.

The average tenant response of more than 100% in a study about cleaning duties in shared apartments is probably the product of social desirability bias. Social desirability bias occurs when respondents give answers that they think are socially acceptable or desirable, rather than their true opinions or behavior.

In this case, tenants may have overstated their contribution to cleaning the apartment, in order to appear more helpful or responsible, leading to an average percentage higher than 100%.

A $100 bill and a dime differ by a magnitude of 3.

Orders of magnitude can be used in order to define large quantities efficiently and more easily. A dime is a currency used in the US that is equivalent to 0.10 dollars.

So we can represent a dime as 10-¹ of a dollar

and we can write 100 dollars as 10² of a dollar.

Therefore the difference in the order of magnitude of 100 dollars and a dime would be the difference between the powers or exponents of those two quantities,

That is,

2-(-1) = 3

The function f(x)=√x with f:R→R is injective and surjective but not bijective.

Injective (or one-to-one): f(x) is injective, which means that if f(x1) = f(x2), then x1 = x2. In other words, if the square root of x1 is equal to the square root of x2, then x1 and x2 are equal.

Surjective (or onto): f(x) is surjective, which means that for every y in the codomain (R), there exists an x in the domain (R) such that f(x) = y. In other words, the square root of any real number can always be expressed as a real number.

Bijective: f(x) is not bijective. The square root function is not bijective because it is not defined for negative values of x.

Function: A function f is a function if for every x in the domain of f, there is exactly one y in the codomain of f such that f(x) = y. In other words, each x in the domain is mapped to exactly one y in the codomain.

In the case of f(x) = √x, it is a function. For every x in the domain of f, which is [0,∞), there is exactly one y in the codomain of f, which is [0,∞), such that f(x) = y.
