from his purchased bags, randy counted 120 red candies out of 500 total candies. using a 90% confidence interval for the population proportion, what are the lower and upper limits of the interval? answer choices are rounded to the thousandths place.

Answer: Let's start by setting up the system of inequalities:

x + y ≥ 18 (Enola has at least 18 coins)

0.25x + 0.10y ≤ 3.60 (The total value of her coins is at most $3.60)

To graph this system of inequalities, we can start by graphing the line x + y = 18 (the boundary for the first inequality). This line represents all the possible combinations of x and y that would give Enola exactly 18 coins. To graph this line, we can plot two points on it and connect them with a straight line. For example, if x = 0, then y = 18, and if y = 0, then x = 18. So the line passes through the points (0, 18) and (18, 0).

Next, we need to shade the region that satisfies the second inequality. To do this, we can rearrange the inequality to get:

y ≤ (3.60 - 0.25x) / 0.10

This inequality represents all the possible combinations of x and y that would give Enola a total value of coins at most $3.60. We can graph this inequality by shading the region below the line y = (3.60 - 0.25x) / 0.10.

Putting both of these graphs together, we get:

Graph of system of inequalities

One possible solution to this system of inequalities is (x, y) = (10, 8). This corresponds to Enola having 10 quarters and 8 dimes, for a total of 18 coins. The total value of her coins is:

0.25(10) + 0.10(8) = 2.50 + 0.80 = 3.30

Since 3.30 is at most $3.60, this solution satisfies both inequalities. Note that there may be other possible solutions as well.

Step-by-step explanation:

The system of inequalities is solved by plotting the inequalities in the xy-plane and finding the overlapping region. One possible solution for the number of quarters (x) and dimes (y) Enola could have that meets the conditions is x = 8 and y = 10.

The subject of this question is inequalities. Enola has x quarters and y dimes. Each quarter is worth $0.25 and each dime is worth $0.10. Therefore, the total amount of money she has is $0.25x + $0.10y. Since she has at least 18 coins, we have the inequality x + y >=18. Since the total money is at most $3.60, we have the inequality $0.25x + $0.10y <= 3.60. Because we are dealing with a whole number of coins, x and y should be integers. The solution of this system of inequalities can be found graphically by plotting these inequalities in the xy-plane and finding the overlapping region. One possible solution is x = 8 and y = 10.

Step-by-step explanation:

To estimate the size of the town, we can use a proportion.

Number of middle school students / Total town population = Number of interviewed middle schoolers / Total number of interviewed townspeople

Let x be the total town population. Then we have:

800 / x = 40 / 125

Simplifying this proportion, we get:

40x = 800×125

40x = 100000

x = 100000 / 40

x = 2500

Step-by-step explanation:

Area of circle =   pi r^2

10 inch = pi (5)^2 = 25 pi

12 inch = pi (6)^2 = 36 pi

12 inch is 11pi bigger

    percentage:  11 pi is what percentage of 25 pi ?

        11 pi / 25 pi x 100%  = 44 % bigger

The area of a pizza increases with the square of the diameter. Therefore, a 10-inch pizza has an area of [tex]π*(10/2)^2= 78.54[/tex]  square inches, and a 12-inch pizza has an area of [tex]π*(12/2)^2 = 113.10[/tex] square inches. This is an increase of 113.10 - 78.54 = 34.56 square inches, or an increase of 44.2%.

To explain further, the diameter of a pizza is measured from one side to the other through the center of the pizza. As the diameter of the pizza increases, the area of the pizza increases. This is because the area of a pizza is calculated as [tex]π*(d/2)^2[/tex], where d is the diameter. So, if the diameter increases, the area increases as well.

For example, if a 10-inch pizza has an area of 78.54 square inches, a 12-inch pizza would have an area of 113.10 square inches. This is an increase of 113.10 - 78.54 = 34.56 square inches, or an increase of 44.2%. This is because the diameter of the pizza has increased by 2 inches (10 inches to 12 inches), and the area has increased by 44.2%.

It is important to note that increasing the diameter of the pizza does not just increase the circumference of the pizza, but also the area. The increase in area is directly related to the increase in diameter, and can be calculated by taking the difference between the areas of the two pizzas.

A prism is a polyhedron with an n-sided polygonal basis, a second base that is a shifted copy of the first base, and n extra faces (necessarily all parallelograms), with two connecting the corresponding sides of the base. All cross sections that are parallel to the base are translations of it. A prism is a two-sided, solid, three-dimensional object with two faces. It has the same cross-sections, flat sides, and similar bases. Faces of a prism are parallelograms or rectangles with no bases. A prism is a refracting item that is homogeneous, solid, and transparent, contained by two planes that are obliquely oriented to one another. A typical prism has two triangular faces and three parallel rectangular faces. They are made of either glass or metal.  

To calculate the volume of a triangular prism, multiply the area of the triangular base by the prism's height.

Triangle area = 1/2 * base * height

Triangle area = 1/2 * 8 cm * 6 cm

Triangle area = 24 cm2

We must now determine the prism's height. The diagram shows that the prism has a height of 10 cm.

Finally, the volume of the triangular prism can be calculated by multiplying the area of the triangle base by the prism's height:

Prism volume = base area * The prism's height

Prism volume = 24 cm2 * 10 cm

Prism volume = 240 cm3

As a result, the compound inequality has the following solution:               -1 ≤ x < 28/9

An inequality in mathematics is a claim that two values or expressions are not equivalent to one another. A spectrum of potential values for a variable can be described by an inequality, which can also be used to compare the values of two quantities. There are various kinds of inequality, such as: Inequalities involving linear expressions or formulae are referred to as linear inequalities. An illustration of a linear inequality is 2x + 3 7. Inequalities involving quadratic expressions or formulae are known as quadratic inequalities. x2 - 4x + 3 > 0 is an illustration of a quadratic equation.

given

The compound inequality is as follows:

-4 ≤ 3x - 1 < 8

This can be resolved by splitting it into two distinct inequalities:

-4 <= 3x - 1 and 3x - 1 < 8

By adding 1 to both sides and dividing by 3, we can solve the first equation for x:

-4 + 1 ≤ 3x - 1 + 1/3

-3/3 ≤ x

-1 ≤ x

Solving the second inequality for x, we add 1 to both sides and split by 3:

3x - 1 + 1/3 < 8 + 1/3

3x < 9 + 1/3

3x < 28/3

x < 28/9

Answer:

A) This sequence is geometric.

B) In the equation A(x) = 20000(1.05)^(x-1):

A(x) represents the amount of money in the savings account after x years.

20000 represents the initial amount of money in the savings account.

1.05 represents the interest rate, which is compounded annually.

(x-1) represents the number of compounding periods, which is one less than the number of years because the initial amount is not compounded.

C) To find out how much money we would have in the savings account in 11 years when Kolton starts college, we can substitute x = 11 into the equation and simplify:

A(11) = 20000(1.05)^(11-1)

A(11) = 20000(1.05)^10

A(11) ≈ 35,123.58

Therefore, if we only relied on the interest to build our savings for 11 years, we would have approximately $35,123.58 in the savings account when Kolton starts college. However, this amount may not be enough to cover the total cost of college, so it is important to continue making regular deposits to the savings account.

a = 5, b = 25, c = 0

step by step explanation:

Let the three numbers be a, b, and c. Then, we have the following system of equations:

a + b = c + 20 (1)

a + c = b + 30 (2)

b + c = a + 40 (3)

Adding all three equations together, we get:

2(a + b + c) = 90

Simplifying, we get:

a + b + c = 45

Now, using the hint given in the problem, we can write:

c = x - 10

b = a + 20

a + (a + 20) = (x - 10) + 30

Simplifying this equation, we get:

2a + 20 = x + 20

Solving for x, we get:

x = 2a

Substituting this value of x in the equation c = x - 10, we get:

c = 2a - 10

Now we can express b and c in terms of a:

b = a + 20

c = 2a - 10

Therefore, three numbers that satisfy the given conditions are:

a = 5, b = 25, c = 0

We can verify that the sum of any pair exceeds the third by the given amounts:

a + b = 30 > c + 20 = 20

a + c = 5 > b + 30 = 25

b + c = 15 > a + 40 = 45

To find the number of ways a person can go from P to Q and return by a different bus, we can use the combination formula:

nCr = n! / (r! × (n-r)!)

where n is the total number of options, and r is the number of choices we want to make.

In this case, there are 25 buses running between P and Q, so the total number of options for going from P to Q and returning by a different bus is 25 × 24 (since we have 25 choices for the first leg of the journey, and 24 choices for the second leg).

To find the total number of ways to make this choice, we can use the combination formula with n = 25×24 and r = 2

nCr = (25×24)! / (2! × (25×24-2)!)

Let's start by finding the formula for the surface area of a sphere. The surface area (A) of a sphere with radius (r) is given by the formula:

A = 4πr²

Now, we need to find the rate at which the surface area is changing with respect to time (t) when the radius is 8 meters and the rate of change of radius is 3 m/s.

To find dA/dt, we need to differentiate the formula for surface area with respect to time, using the chain rule:

dA/dt = d/dt (4πr²) = 8πr (dr/dt)

Here, we have used the fact that the derivative of r² with respect to time is 2r (dr/dt) by the chain rule. Now, we can substitute the given values into the formula to find the rate of change of surface area:

r = 8 m (given)

dr/dt = -3 m/s (negative sign because the radius is decreasing)

To find out how many more hours Jason worked than Sheldon, we need to subtract the number of hours Sheldon worked from the number of hours Jason worked:

Jason's hours = 14/3

Sheldon's hours = 25/6

Jason's hours - Sheldon's hours = (14/3) - (25/6)

To subtract fractions, we need to have a common denominator, which in this case would be 6:

(14/3) - (25/6) = (28/6) - (25/6) = 3/6

Simplifying the result, we get:

3/6 = 1/2

Therefore, Jason worked 1/2 more hours than Sheldon.

Jason worked 1/3 more hours than Sheldon.

To find out how many more hours Jason worked than Sheldon, we need to subtract the number of hours Sheldon worked from the number of hours Jason worked.

Jason worked for 14/3 hours, which can be simplified to 4 and 2/3 hours. Sheldon worked for 25/6 hours, which can be simplified to 4 and 1/6 hours.

Subtracting the hours Sheldon worked from the hours Jason worked, we get: 4 and 2/3 - 4 and 1/6 = 2/3 - 1/6 = 1/3.

Step-by-step explanation:

You want the average density of a planet with radius 6052 km and mass 4.87×10^27 g.

The mass is given in grams, and the corresponding unit in the desired answer is kilograms. There are 1000 g in 1 kg, so 4.87×10^27 g = 4.87×10^24 kg.

The radius is given in km, and the corresponding unit in the desired answer is meters. There are 1000 meters in 1 km, so 6052 km = 6052×10^3 m. (We could adjust the decimal point, but we choose to let the calculator do that.)

The units of density tell you it is computed by dividing the mass by the volume:

  ρ = mass/volume

The volume of the sphere is found using the given formula, so the density is ...

  ρ = (4.87×10^24 kg)/(4/3π(6052×10^3 m)^3)

  ρ ≈ 5240 kg/m³

The average density of the planet is about 5240 kg/m³.

Additional comment

This is comparable to the average density of Earth, which is about 5520 kg/m³.

Step-by-step explanation: I had a similar question consisting of the same numbers.

The second fuel line must be able to fill the oil tanker at a rate of 2.67 tanks per hour in order to fill the tanker in 45 minutes when used together with the first fuel line.

Rate of the first fuel line = 1 tank / 3 hours = 1/3 tanks per hour

Let's assume that the rate of the second fuel line is x tanks per hour. When both fuel lines are used together, their combined rate is the sum of their individual rates:

Combined rate = Rate of the first fuel line + Rate of the second fuel line

1 tank / 0.75 hours = (1/3) tank per hour + x tanks per hour

Simplifying the equation, we get:

1 tank / 0.75 hours - 1/3 tank per hour = x tanks per hour

x = (1 tank / 0.75 hours - 1/3 tank per hour)

x = 2.67 tanks per hour

Therefore, the second fuel line must be able to fill the oil tanker at a rate of 2.67 tanks per hour in order to fill the tanker in 45 minutes when used together with the first fuel line.
