According to the question, Eight kids were chosen at random to take part in a brand-new educational program that emphasizes both academics and mental health education between middle school and high school. The average annual income is $29432. The standard deviation is unknown.

The probability level is given to be 5%.

When the p-value is less than or equal to your significance level, reject the null hypothesis. The alternative theory, which contends that the effect is widespread, is supported by your sample data.

A probability level of 0.05 means that the new curriculum significantly affects the earning potential.

To determine whether the furnace will be adequate for a 1,400 square foot house with a 9-foot ceiling, we need to calculate the volume of the house and compare it to the volume the furnace is designed to heat.

The volume of the house can be found by multiplying the square footage by the ceiling height:

1,400 sq ft x 9 ft = 12,600 cubic feet

Since the furnace is designed to heat 10,000 cubic feet, and the house has a volume of 12,600 cubic feet, the furnace may not be adequate for heating the house. The furnace is not capable to heat the entire house.

Answer:

C)Only III follows

Step-by-step explanation:

Let's review the conclusions;

I. Some proses are songs.

This is false because of the statement; No song is prose.

II. Some epics are lullabies.

This is false because of the following statements; A lullaby is a song. and No song is prose.

III. Some songs are lullabies.

This follows because of the statement; A lullaby is a song.

The correct option is;

C)Only III follows

The correct conclusion based on the logical statements is C) Only III follows.

1. A lullaby is a song.

2. No song is prose.

3. Some proses are epics.

I. Some proses are songs.

II. Some epics are lullabies.

III. Some songs are lullabies.

The first conclusion that some proses are songs is not sound because the earlier claim is that "no song is prose." In the same light, the second conclusion is incorrect because a lullaby is usually a song as asserted in statement 1. While epics can be prose or poem, a lullaby is not prose but a poem or a song.

Thus, the correct conclusion based on the logical statements is C) Only III follows.

Answer:

Step-by-step explanation:

You want to solve graphically the system of inequalities expressing that Rashaad has no less than a total of 18 dimes (x) and nickels (y) with a combined value of at most $1.50, of which at least 4 are dimes.

An inequality can be written for each of the constraints:

  x + y ≥ 18 . . . . . . . no less than 18 coins

  0.10x +0.05y ≤ 1.50 . . . . . . at most $1.50 in value

  x ≥ 4 . . . . . . . . . . at least 4 dimes

A graph of these inequalities is attached. The marked points are the vertices of the triangular solution space. Each is a possible solution, along with all of the grid points inside the triangle.

One possible solution is 4 dimes and 22 nickels, for a total of 26 coins with a value of $1.50.

Using graph to solve the system of linear inequality the most likely solutions will be 4 dimes and 22 nickels, for a total of 26 coins with a value of $1.50

Systems of linear inequalities are equations with two or more linear inequalities that contain two or more variables. These equations can be used to represent real-world problems and to find the solutions of such problems. The solutions of a system of linear inequalities are all the points that are common to all of the linear inequalities in the system.

In this problem, we have to define our variables and then solve this using graphical method. The point of intersection between the two lines lies the solution to the linear inequality.

Let;

x + y ≥ 18

0.1x + 0.05y ≤ 1.50

x ≥4

Using a graphing calculator to solve this,

The possible solutions is 4 dimes and 22 nickels, for a total of 26 coins with a value of $1.50.

The probability that a patient with a negative result is truly HIV-free is 0.999.

To find the probability that confirms that the result of the HIV test is negative, we must take into account the information provided in the information and perform the following mathematical operation.

The probability that No HIV and test positive is:

P = 0.85 * 0.985

P = 0.8372

The probability that HIV and test negative is:

P = 0.15 * 0.003

P = 0.00045

The probability that No HIV and negative test of HIV and negative test is:

P = 0.00045 + 0.8372

P = 0.8377

P = (NOT HIV / Test)

P = 0.8372 / 0.8377

P = 0.999

According to the above, the probability that a patient with a negative result is truly HIV-free is 0.999.

3. The volume of the Pringle Chips container is approximately 2034.72 cubic inches.

4. The cake takes up approximately 7317 cubic inches of space.

5. The volume of foam in the model of the volcano is approximately 7234.08 cubic centimeters.

1. The units for Volume are always cubed.

2. Volume is the amount of space an object takes up. True.

3. To calculate the volume of the Pringle Chips container, we need to find the volume of a cylinder. The formula for the volume of a cylinder is V = πr^2h, where π is a constant (approximately 3.14), r is the radius, and h is the height. Given that the diameter is 9 inches, the radius would be half of that, which is 4.5 inches. Substituting the values into the formula, we have:

V = 3.14 * (4.5)^2 * 32

V = 3.14 * 20.25 * 32

V ≈ 2034.72 cubic inches

4. To find the volume of the 3-tier cake, we need to find the volume of each tier separately and then add them together. Since all the tiers are cylinders, we can use the formula V = πr^2h.

Tier 1:

V1 = 3.14 * (12)^2 * 10 = 4521.6 cubic inches

Tier 2:

V2 = 3.14 * (8)^2 * 10 = 2010.4 cubic inches

Tier 3:

V3 = 3.14 * (5)^2 * 10 = 785 cubic inches

Total volume:

Total V = V1 + V2 + V3

Total V = 4521.6 + 2010.4 + 785

Total V ≈ 7317 cubic inches

5. To find the volume of the Styrofoam model of the volcano, we can use the formula for the volume of a cone, V = (1/3)πr^2h. Given that the diameter is 48 centimeters, the radius would be half of that, which is 24 centimeters. Substituting the values into the formula, we have:

V = (1/3) * 3.14 * (24)^2 * 12

V = (1/3) * 3.14 * 576 * 12

V ≈ 7234.08 cubic centimeters

Answer:

a. City B

b. City A

c. City A

d. City A

Step-by-step explanation:

a. Max temperature for City A = 84°F

Max temperature for City B = 86° F

Therefore, City B has the highest noon temperature

b. City A median noon temperature = 80°F

City B median noon temperature = 72°F

Therefore, City A has the larger median noon temperature.

c. City A IQR = 83 - 75 = 8

City B IQR = 77 - 70 = 7

Therefore, City A has noon temperatures with a higher IQR

d. The median of City A is greater than 78°F, this means about half of its noon temperature are more than 78°F, therefore, City A had more noon temperatures above 78°F compared to City B.

⇒ (2, - 4) and (3, - 4)

An algebraic equation with the second degree of the variable is called an Quadratic equation.

Given that;

The equation is,

⇒ y = x² - 5x - 2

⇒ - 4 = x² - 5x - 2

Now, We can draw the graph of function y = x² - 5x - 2 as shown in figure.

Then, For equation - 4 = x² - 5x - 2;

Value of y = - 4

Hence, By the graph of y = x² - 5x - 2 we can see that at y = - 4 there are two value of x;

⇒ x = 2, 3
