The best estimate for the number of fish is that there are 82 yellow fish and 18 green fish, which you can calculate using the rule of three. This estimate is expected to be accurate.

This can be calculated using a rule of three as follows. Let's start with the yellow fish:

53 = 65

x    = 100

53 x 100 / 65 = 82 yellow fish

Green fish:

12 = 65

x = 100

12 x 100 / 65= 18 green fish

This estimate is expected to be accurate; however, there might be small differences in real life such as 80 yellow fish and 20 green fish.

At a price of $3, the total revenue will be the greatest, and the company will sell 3 units at that price.

To find the total revenue at each price, we can multiply the price by the corresponding quantity.

Price        Quantity          Total Revenue

$6                0                      $0

$5                 1                       $5

$4                 2                       $8

$3                 3                        $9

$2                 4                         $8

$1                  5                          $5

To find the price at which total revenue is the greatest, we look for the highest value in the Total Revenue column.

In this case, the highest total revenue is $9, which occurs when the price is $3.

At a price of $3, the company will sell 3 units (as indicated in the Quantity column).

Answer:

Step-by-step explanation:

You can answer this directly from your knowledge that the lengths (3, 4, 5) form a right triangle.

If you study Pythagorean triples, you find that for an odd-length short side, the other two sides can be consecutive integers whose sum is the square of the short side. (You can see that in the solution below.) Here are a few examples:

  short side 3: Other sides are 4, 5. 4+5 = 9 = 3^2

  short side 5: Other sides are 12, 13. 12+13 = 25 = 5^2

  short side 13: Other sides are 84, 85. 84+85 = 169 = 13^2

__

Or, you can solve this making use of the Pythagorean theorem. The sum of the squares of the two sides is the square of the hypotenuse. If x is the second side, then ...

  3² +x² = (x +1)²

  3² = 2x +1 . . . . . expand the right side and subtract x²

  x = (3² -1)/2 = 4

  x+1 = 5

The second side is 4 m; the third side is 5 m.

Answer:

3.5

Step-by-step explanation:

I recommend using a calculator. Divide 7/2.

Differentiating both sides of

\(x^2 + 2xy - y^2 + x = 20\)

with respect to \(x\) yields

\(2x + 2y + 2x \dfrac{dy}{dx} - 2y \dfrac{dy}{dx} + 1 = 0 \\\\ \implies (2x-2y) \dfrac{dy}{dx} = -1 - 2x - 2y \\\\ \implies \dfrac{dy}{dx} = \dfrac{1 + 2x + 2y}{2(y-x)}\)

At the point (3, 4) (so \(x=3\) and \(y=4\)), the tangent line has slope

\(\dfrac{dy}{dx} = \dfrac{1 + 2\times3 + 2\times4}{2(4-3)} = \dfrac{15}2\)

Then the tangent line to (3, 4) has equation

\(y - 4 = \dfrac{15}2 (x - 3) \implies \boxed{y = \dfrac{15}2 x - \dfrac{37}2}\)

A bank is eligible to ask for a service fee because it provides various services to its customers that incur costs.

Banks are financial institutions that offer a range of services such as deposit accounts, loans, credit cards, money transfers, and investment options. These services require infrastructure, technology, staff, and administrative costs to operate effectively.

The service fee charged by a bank helps cover these operational expenses and ensures the bank can continue providing quality services to its customers. Additionally, banks may also charge fees to generate revenue and earn profits. Banks are businesses that need to maintain financial sustainability, and service fees contribute to their overall revenue stream.

Banks typically outline their fee structure and disclose the applicable charges in their terms and conditions or fee schedules. Common examples of service fees include monthly maintenance fees for deposit accounts, transaction fees for certain types of transactions, overdraft fees, wire transfer fees, and fees for additional banking services.

It's important for banks to be transparent about their fee structure and provide clear information to customers regarding the charges. Customers can then make informed decisions about which services to use and understand the costs associated with those services.

Step-by-step explanation:

y = ax + b

a is the slope of the line. it is expressed as the ratio

y coordinate change / x coordinate change

when going from one point to the other.

b is the y-intercept (the y value when x = 0).

once we have the slope, we get b by using the coordinates of one of the given points as x and y in the equation and solve for b. or we get the point of the line directly on the y-axis.

we see several marked points.

e.g.

(-4, 4) (0, -4)

x changes by +4 (from -4 to 0)

y changes by -8 (from 4 to -4)

the slope (a) is -8/+4 = -2

the y-intercept is given by the point (0, -4), because this is where x=0.

so, it is -4

and the line equation is

y = -2x - 4

a) The value of x is 21

b) The value of the expression is 135.

c) The value of the expression is 135.

Here we know that the lines G and M are parallel, meaning that the two shown angles are alternarte exterior angles, and thus, have the same measure, then we can write:

5*(x + 6) = 9*(x - 6)

We can solve that linear equation for x:

5x + 30 = 9x - 54

30 + 54 = 9x - 5x

84 = 4x

84/4 = x

21 = x

Then the measures of the angles are:

a1 = 5*(21 + 6) = 135°

a2 = 9*(21 - 6) = 135°

Answer:

32/13

Step-by-step explanation:

To evaluate the expression Z₂ * Z3 / Z₁, we first need to find the complex numbers Z₂ * Z3 and Z₁.

Z₂ * Z3 = -2 + 3i * 4 + 2i = (-8 + 14i) + (-6 + 6i) = -8 + 8i

Z₁ = 3 - 2i

So, Z₂ * Z3 / Z₁ = (-8 + 8i) / (3 - 2i)

We can simplify this expression by multiplying the numerator and denominator by the complex conjugate of the denominator, which is (3 + 2i).

Z₂ * Z3 / Z₁ = (-8 + 8i) / (3 - 2i) * (3 + 2i) / (3 + 2i) = (-8 + 8i) * (3 + 2i) / (3 - 2i) * (3 + 2i)

Z₂ * Z3 / Z₁ = ((-8 * 3 + 8 * 2i) + (8 * 3 + 8 * 2i)) / (3^2 + (-2i)^2) = (16 + 16i) / 13

Therefore, Z₂ * Z3 / Z₁ = (16 + 16i) / 13.

Answer: C) Either μ is in the interval or it is not. Therefore, the probability that μ is in this interval is 0 or 1.

Step-by-step explanation: A 95% Confidence interval shows that there is a 95% confidence that the true parameter is between the lower and upper limits.

A CI is not a probability that the true parameter is in between the interval. The true parameter is either in the interval or not.

So, probability of falling between the limits is 0 (no chance of being in this interval) or 1 (100% possibility of being in this interval).

Then, "either μ is in the interval or it is not. therefore, the probability that μ is in this interval is 0 or 1." is correct.

La altura de la cabaña es 8,25 metros.

En un triángulo isósceles la pendiente, esto es, la relación entre altura (\(h\)), en metros, y longitud de base (\(w\)), en metros, es constante. Por tanto, podemos determinar la altura a partir de la siguiente relación:

\(h = r\cdot w\) (1)

Donde \(r\) es la relación entre altura y longitud de base, sin unidad.

Si sabemos que \(r = 1,5\) y \(w = 5,5 m\), entonces la altura de la cabaña es:

\(h = (1,5)\cdot (5,5\,m)\)

\(h = 8,25\,m\)

Overall, a truly representative sample would need to be selected randomly from the entire population of interest to get accurate results.

"Randomly selected" refers to the process of choosing something without any predictable pattern or predetermined criteria. When something is randomly selected, it means that it is chosen by chance, without any intentional bias or preference towards any particular option. This can be done through various methods, such as using a random number generator or drawing names out of a hat. The purpose of random selection is often to ensure fairness and equal opportunity, especially in situations where multiple options or individuals are being considered for a particular opportunity or reward.

by the question.

To obtain a representative sample of the population of interest, the sample should be selected randomly from the population, ensuring that all individuals in the population have an equal chance of being selected.

Without any information about the population and its demographics, it is difficult to determine which sample is most representative. However, here are three potential samples:

Randomly select 500 individuals from the county's population and ask them about the types of activities they want at the library. This sample is likely to be representative if the population is diverse and the sample is randomly selected.

Ask 500 people who regularly use the library about the types of activities they want. While this sample is likely to be biased towards people who already use the library, it may still be representative of people who use the library regularly.

Ask 500 people who live within a mile of the library about the types of activities they want. This sample may be biased towards people who live close to the library and does not include people who live further away, but it may still be representative of people who are most likely to use the library.

Answer:

Step-by-step explanation:

Suppose that you have a set of points, where the x-coordinates represent the number of months since you purchased a computer and the y-coordinates represent how much the computer is worth. Would you know how to plot these points on a Cartesian plane? How about if the situation were reversed and you had the plotted points? Could you come up with the coordinates of the points and the function rule that would generate these points?

Functions on a Cartesian Plane

Once a table has been created for a function, the next step is to visualize the relationship by graphing the coordinates of each data point. Data points are formatted as (x,y), where the first coordinate represents the horizontal distance from the origin (remember that the origin is the point where the axes intersect). The second coordinate represents the vertical distance from the origin.

Figure 4.1.5.1

To graph a coordinate point such as (4, 2), we start at the origin.

Because the first coordinate is positive four, we move 4 units to the right.

From this location, since the second coordinate is positive two, we move 2 units up.

Figure 4.1.5.2

Plot the following coordinate points on the Cartesian plane:

(5, 3)

(-2, 6)

(3, -4)

(-5, -7)

We show all the coordinate points on the same plot.
