Answer:

To find the smallest integer value that the frequency density axis needs to reach, we need to first calculate the frequency density for each class interval. The frequency density is calculated by dividing the frequency of each interval by its corresponding class width.

The class widths are:

14 - 0 = 14

18 - 14 = 4

20 - 18 = 2

25 - 20 = 5

40 - 25 = 15

The frequency densities are:

21 / 14 = 1.5

28 / 4 = 7

17 / 2 = 8.5

22 / 5 = 4.4

33 / 15 = 2.2

To plot all of the data, we need to find the maximum frequency density and round it up to the nearest integer. In this case, the maximum frequency density is 8.5, so we need to round it up to 9. Therefore, the smallest integer value that the frequency density axis needs to reach is 9.

Therefore, the manager should not mix any cashews with the peanuts to ensure no change in revenue.

Revenue is the total amount of money a business or organization earns from selling goods or services during a specific period. It is calculated by multiplying the price of each unit sold by the total number of units sold. Revenue represents the income generated by a company's normal business activities and is used to pay for expenses, invest in future growth, and distribute profits to shareholders or owners. It is an important metric for measuring the financial health and performance of a business.

by the question.

Let's assume that x pounds of cashews are mixed with the 30 pounds of peanuts.

The total weight of the mixture would then be 30 + x pounds.

To ensure no change in revenue, the amount earned by selling the peanuts and cashews separately should be equal to the amount earned by selling the mixture.

The revenue earned by selling 30 pounds of peanuts is 30 x $1.50 = $45.

If y pounds of cashews are sold separately, the revenue earned would be y x $4.00 = $4y.

The total revenue earned by selling the peanuts and cashews separately would be $45 + $4y.

When the 30 pounds of peanuts and x pounds of cashews are mixed together and sold for $3.50 per pound, the total revenue earned would be (30 + x) x $3.50 = $105 + $3.50x.

Since the revenues from selling the mixture and selling the peanuts and cashews separately are equal, we can set the equations equal to each other and solve for x:

$45 + $4y = $105 + $3.50x

$3.50x - $4y = -$60

x - 4/7y = -60/7

We still have one unknown variable y, so we need another equation to solve for both x and y.

We know that the total weight of the mixture is 30 + x pounds. If we add y pounds of cashews to the mixture, the total weight becomes:

30 + x + y

We can set this equal to the total weight of the peanuts and cashews sold separately:

30 + y

Solving for y:

30 + x + y = 30 + y

x = 0

To vertically expand a function by a factor of 2, we multiply the function by 2. Thus, the transformed function becomes g(x) = 2f(x) = [tex]2(x^3)[/tex].

To translate a function down 2 units, we subtract 2 from the original function. Thus, the transformed function becomes h(x) = g(x) - 2 = 2[tex](x^3)[/tex] - 2.

So the equation of the transformed function is h(x) = 2[tex](x^3)[/tex] - 2.

Graphically, the transformation of the function f(x) = [tex]x^3[/tex] into h(x) = 2[tex](x^3)[/tex] - 2 means that the graph of h(x) is twice as tall as the graph of f(x) and shifted 2 units downwards.

Increase in the level of confidence and increase in the population standard deviation will increase the width of a confidence interval and increasing the sample size will decrease the width of a confidence interval.

(a) Increasing the level of confidence will increase the width of a confidence interval. This is because a higher level of confidence requires a larger margin of error, which in turn increases the width of the interval.

(b) Increasing the sample size will decrease the width of a confidence interval. This is because a larger sample size leads to a more precise estimate of the population parameter, which reduces the amount of uncertainty and therefore narrows the interval.

(c) Increasing the population standard deviation will increase the width of a confidence interval. This is because a larger standard deviation indicates greater variability in the population, which in turn requires a larger margin of error and therefore widens the interval.

The exponential growth rate is approximately 3.1% per year, and the equation is C(t) = 0.22 * e^(0.031t). The cost of a bottle of ketchup in 2012 would be approximately $1.72.

To find the exponential growth rate, we use the formula:

r = (ln(P2/P1)) / (t2 - t1)

where P1 is the initial value, P2 is the final value, t1 is the initial time, t2 is the final time, and ln denotes the natural logarithm. Substituting the values we get:

r = (ln(1.39/0.22)) / (2007-1966) = 0.0271 or 2.7% (to the nearest tenth of a percent)

The equation for exponential growth is:

C(t) = C0 * e^(rt)

where C0 is the initial cost and C(t) is the cost at time t. Substituting the values we get:

C(t) = 0.22 * e^(0.0271t)

To find the cost of a bottle of ketchup in 2012, we substitute t = 2012 in the above equation:

Answer: Let's draw a diagram to visualize the situation:

                 / |  25°

         12000 /  |

              /    |

             /     |

            /θ     | B (plane)

           A       |

In this diagram, the pilot of the airplane is located at point B and the water tower is located at point C. The angle of depression from the airplane to the base of the tower is 25°. We are asked to find the length of the line of sight from the airplane to the tower, which is the distance AC.

We can use trigonometry to solve for AC. In particular, we can use the tangent function, which relates the opposite side to the adjacent side of a right triangle:

tan(θ) = opposite / adjacent

In this case, the opposite side is BC (the height of the water tower) and the adjacent side is AB (the distance from the airplane to the base of the tower). We can rearrange the equation to solve for AB:

AB = BC / tan(θ)

We know that BC is the height of the water tower, but we don't have that information. However, we can use the fact that the angle of depression is 25° to find BC. The angle of depression is the angle between the horizontal line (which we can assume is the same as the ground level) and the line of sight from the airplane to the base of the tower. Therefore, the angle between the line of sight and the vertical line (which is perpendicular to the ground) is 90° - 25° = 65°. This means that the triangle ABC is a right triangle, with angle θ = 65°.

Now we can use trigonometry again to find BC, using the sine function:

sin(θ) = opposite / hypotenuse

In this case, the opposite side is BC (the height of the water tower) and the hypotenuse is AC (the line of sight from the airplane to the tower). We can rearrange the equation to solve for BC:

BC = sin(θ) x AC

We know that θ = 65° and sin(θ) ≈ 0.9063 (you can use a calculator to find this value). Substituting these values into the equation gives us:

BC = 0.9063 x AC

Now we can substitute this expression for BC into the equation we derived earlier:

AB = BC / tan(θ) = (0.9063 x AC) / tan(65°)

We can simplify this expression by noting that tan(65°) ≈ 2.1445 (you can use a calculator to find this value). Substituting this value gives us:

AB = (0.9063 x AC) / 2.1445

Multiplying both sides by 2.1445 gives us:

2.1445 x AB = 0.9063 x AC

Dividing both sides by 0.9063 gives us:

AC = (2.1445 x AB) / 0.9063

We know that AB is the altitude of the airplane, which is given as 12,000 feet. Substituting this value gives us:

AC = (2.1445 x 12,000) / 0.9063 ≈ 28,406 feet

Therefore, the length of the line of sight from the airplane to the water tower is approximately 28,406 feet.

Answer:

Step-by-step explanation:

Depending on the correlations between the days, the answer can be anywhere from 25% (perfect correlation) to 100% (for example, first four days mutually exclusive).

If you assume the days are independent, which may be what you intended to ask but is not actually a good assumption when it comes to the weather, then the probability is 1 - (1-0.25)^5 = 76%

The issue pertains to probability theory, and specifically the calculation of the likelihood of precipitation on a particular day. We need to find the total probability that it rains at least three out of five days, and this would require enumerating and counting all possible outcomes.

This is a problem of probability related to weather forecasts, specifically concerned with the chance of rain. The first day has an independent probability of 1/2 (rain or no rain). Thereafter each day's weather depends on the previous day's. If it rained the day before, there's a 2/3 chance it will rain the next day, and 1/3 chance it won't. If it didn't rain, those chances are reversed.

To get the probability that it rains at least three out of five days, we will think about it in terms of the total possible outcomes and the desired outcomes. The problem can be solved by counting the number of ways that we can have 3, 4 or 5 rainy days out of 5 and then multiplying each by the probability of that particular event.

By following these steps, we will arrive at the total probability, which might require a sophisticated understanding of probability theory.

From  following equations option B  will produce the hyperbola graph shown in the figure

what is hyperbola ?

A hyperbola is a type of conic section, which is a curve that is formed by the intersection of a plane and a double cone. A hyperbola can also be defined as the set of all points in a plane, the difference of whose distances from two fixed points (called the foci) is a constant.

In the given question,

Based on the shape of the hyperbola shown on the y-axis graph, we can tell that the hyperbola has a vertical transverse axis, which means that its equation must have the form:

(y - k)² / a² - (x - h)²/ b² = 1

where (h, k) is the center of the hyperbola, a is the distance from the center to the vertices, and b is the distance from the center to the co-vertices.

Option A is not correct because it produces a hyperbola with a horizontal transverse axis, whereas the given graph has a hyperbola with a vertical transverse axis.

We can eliminate option D since its equation has a transverse axis that is not vertical.

Next, we can eliminate option A since the coefficient of x² is positive, which means that the transverse axis is horizontal.

Option C has a transverse axis that is also horizontal, so we can eliminate it as well.

That leaves us with option B, which has a vertical transverse axis and its equation fits the form we determined earlier. Therefore, the equation Y²/9 - x²/4=1 will produce the hyperbola shown on the y-axis graph

Answer:

p = 125

Step-by-step explanation:

Given p is inversely proportional to q³ then the equation relating them is

p = [tex]\frac{k}{q^3}[/tex] ← k is the constant of proportion

To find k use the condition p = 9 when q is 5, then

9 = [tex]\frac{k}{5^3}[/tex] = [tex]\frac{k}{125}[/tex] ( multiply both sides by 125 )

k = 1125

p = [tex]\frac{1125}{q^3}[/tex] ← equation of proportion

When q = 3, then

p = [tex]\frac{1125}{3^3}[/tex] = [tex]\frac{1125}{9}[/tex] = 125

To find the frequency with the largest amplitude, we can assume that the particular solution to the given differential equation is of the form:

y(t) = Aeiwt

Taking the first and second derivatives of y(t), we get:

dy/dt = iwtAeiwt

The size of the angle PRQ is 300 degrees.

What is congruent?

The term “congruent” means exactly equal shape and size. This shape and size should remain equal, even when we flip, turn, or rotate the shapes.

In a regular 12-sided polygon, each interior angle has a measure of:

(12 - 2) × 180° / 12 = 150°

Since PR is diagonal, it divides the 12-sided polygon into two congruent triangles. Therefore, the angle PQR is half of the angle PRQ.

Let x be the measure of angle PRQ. Then we have:

x + 150° + 150° = 180° (sum of angles in triangle PQR)

Simplifying the equation, we get:

x = 180° - 150° - 150° = -120°

However, since x is an angle in a triangle, it must be positive. Therefore, we take the supplement of x, which is:

180° - x = 180° - (-120°) = 300°

Hence, the size of the angle PRQ is 300 degrees.

The cube root function that tells the side lengths of the​ container, x, in inches for a given​ cost, C is x = (C^(1/3))^3.

We can use the formula for the volume of a cube, which is V = x^3, where x is the side length of the cube. If the cost of producing one cube-shaped container is C dollars, then the cost of producing one unit of volume is C/V = C/x^3 dollars per cubic inch. Solving for x, we get:

x = (C/V)^(1/3)

Substituting V = x^3, we get:

x = (C/x^3)^(1/3)

Simplifying, we get:

x = (C^(1/3)) / (x^(1/3))

Multiplying both sides by x^(1/3), we get:

x^(2/3) = C^(1/3)

The perimeter of a quarter circle can be calculated by adding the length of the arc and the two radii that make up the quarter circle.

The length of the arc of a quarter circle is given by (πr)/2, where r is the radius of the quarter circle and π is approximately 3.142 (as given in the question).

So, for a quarter circle with a radius of 7 cm, the length of the arc would be:

(πr)/2 = (3.142 x 7)/2 = 10.997 cm (rounded to 3 decimal places)

The two radii that make up the quarter circle are each equal to the radius of the quarter circle, so the total length of the two radii would be:

2r = 2 x 7 = 14 cm

Therefore, the perimeter of the quarter circle would be:

10.997 cm + 14 cm = 24.997 cm (rounded to 3 decimal places)

So the perimeter of the quarter circle is approximately 24.997 cm. The digits given by the calculator will depend on the specific calculator used.
