The probability of a random student scoring 84 or more if the maximum score is 95 is approximately 0.1179 or 11.79%.

To find the percentage of students scoring 84 or more, first we need to calculate the z-score using the formula:z = (X - μ) / σwhere X = 84, μ = 72, and σ = 15.2z = (84 - 72) / 15.2z = 0.7895Using a standard normal table or a calculator, we can find the percentage of students scoring 84 or more as:percentage = 1 - P(Z < 0.7895)percentage ≈ 21.4%Therefore, approximately 21.4% of students will score 84 or more on the test.b) To find the probability of a random student scoring 84 or more if the maximum score is 95, we need to first calculate the z-score using the same formula as before:z = (X - μ) / σwhere X = 84, μ = 72, and σ = 15.2z = (84 - 72) / 15.2z = 0.7895Then, we need to convert this z-score to a new z-score based on the maximum score of 95. Using the formula:z = (X - μ) / (max score - μ)σwhere X = 84, μ = 72, σ = 15.2, and max score = 95z = (84 - 72) / (95 - 72)z ≈ 1.19Using a standard normal table or a calculator, we can find the probability of a student scoring 84 or more as:P(Z > 1.19)P(Z > 1.19) ≈ 0.1179Therefore, the probability of a random student scoring 84 or more if the maximum score is 95 is approximately 0.1179 or 11.79%.

The mass of the sheet of metal is 200g. This can also be expressed in other units, such as 0.2 kg or 0.002 tonnes.

The mass of a sheet of metal is directly related to its area and thickness. This means that the mass of a sheet of metal is proportional to the product of its area and its thickness. Mathematically, this can be expressed as the formula M = kAT, where M is the mass, k is a constant, A is the area and T is the thickness.In the given example of a sheet of metal with an area of 250 cm and a thickness of 1mm, we can calculate the mass of the sheet by substituting the given values into the formula: M = k(250)(1) = 200g. The constant k in this example is equal to 0.8 g/cm*mm.Therefore, the mass of the sheet of metal is 200g. This can also be expressed in other units, such as 0.2 kg or 0.002 tonnes.

What is the mass of a sheet of metal with an area of 250cm and a thickness of 1mm?

Answer:

(√122 - √10)/112.

Step-by-step explanation:

The average rate of change of a function f(x) over an interval [a, b] is given by:

average rate of change = (f(b) - f(a))/(b - a)

Here, we have f(x) = √x - 1, a = 10, and b = 122. So, the average rate of change of f(x) from x = 10 to x = 122 is:

(f(122) - f(10))/(122 - 10)

= (√122 - 1 - √10 + 1)/(112)

= (√122 - √10)/112

Therefore, the exact, fully simplified answer for the average rate of change of f(x) from x = 10 to x = 122 is (√122 - √10)/112.

To fully describe a triangular prism, you would need to provide the dimensions of its triangular bases (e.g. base length and height), the length of the prism, and the length and width of the rectangular faces. Thus, option C is correct.

To find the volume of filler material required to surround the triangular prism, we need to first calculate the volume of the box and the volume of the triangular prism.

The volume of the box is given by:

[tex]8[/tex] inches ×  [tex]13[/tex] inches ×  [tex]16[/tex] inches =  [tex]1,664[/tex] cubic inches

The volume of the triangular prism is given by:

[tex](1/2) × 8[/tex] inches ×  [tex]13[/tex] inches ×  [tex]16[/tex] inches = [tex]832[/tex] cubic inches

To completely fill the box, we need to add filler material with a volume equal to the difference between the volume of the box and the volume of the triangular prism, which is:

The probability of event Upper B 1 given event A is approximately 0.0134.

To find P(Upper B 1|A) using Bayes' rule, we need to use the formula:

P(Upper B 1|A) = P(A|Upper B 1) × P(Upper B 1) / P(A)

To find P(A), we can use the law of total probability:

P(A) = P(A|Upper B 1) × P(Upper B 1) + P(A|Upper B 2) × P(Upper B 2) + P(A|Upper B 3) × P(Upper B 3)

Substituting the given values, we get:

P(A) = 0.6 × 0.05 + 0.5 × 0.4 + 0.4 × 0.55

P(A) = 0.029 + 0.2 + 0.22

P(A) = 0.449

Now, substituting the values of P(A|Upper B 1), P(Upper B 1), and P(A) into the Bayes' rule formula, we get:

P(Upper B 1|A) = (0.6 × 0.05) / 0.449

P(Upper B 1|A) = 0.006 / 0.449

P(Upper B 1|A) ≈ 0.0134

Therefore, the probability of event Upper B 1 given event A is approximately 0.0134.

45% of the burgers served were well-done.

What is percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

To find the percentage of well-done burgers, we need to divide the number of well-done burgers by the total number of burgers served and then multiply by 100 to get the percentage.

Total number of burgers served = 9 well-done + 11 medium = 20

Percentage of well-done burgers = (9/20) x 100% = 45%

Therefore, 45% of the burgers served were well-done.

The difference in the loudness of sound when the two teams score is about 14.77 decibels

Sound intensity is defined as the power carried by sound waves per unit area in a direction perpendicular to that area.

We can use the fact that the loudness of sound is measured in decibels (dB) and that the dB scale is logarithmic.

Let's assume that the loudness of the sound when the away team scores is x decibels. Then the loudness of the sound when the home team scores a touchdown is 30 times as great, which means it is 30x decibels.

The difference in loudness between the two scenarios is given by the difference in decibels:

difference in decibels = 10 log (30x/x) = 10 log 30 = 14.77

Therefore, the difference in the loudness of sound when the two teams score is about 14.77 decibels

You need to add 225mL of the 75% alcohol solution to obtain the desired 30% alcohol solution.

To find the amount of 75% alcohol solution needed to obtain a 30% alcohol solution, we must use the formula for dilution:

M1V1 = M2V2

Where M1 is the concentration of the initial solution, V1 is the volume of the initial solution, M2 is the desired concentration, and V2 is the desired volume.

In this case, M1 is 5%, V1 is 675mL, M2 is 30%, and V2 is unknown.

We can rearrange the equation to solve for V2, which is the volume of the 75% alcohol solution needed:

V2 = (M1V1) / M2

V2 = (5% x 675mL) / 30%

V2 = 225mL

Step-by-step explanation:

The picture in this question can be a little deceiving. Each rectangular glass pane is 3 by 10 inches. This means that the picture of the 4 panes overlapping, leaves the center square open. The open area has your inner edges. The question asks for the sum of the inner and outer edges.

Every pane is 10 inches long, so the out perimeter of the figure is 40 inches because the figure has four sides. The rectangles overlap, creating 3 by 3 inch square. 3 inches off either side of a pane leaves 4 inches as the length for the edge of the inner square. Therefore, the perimeter of the inner square is 16 inches.

Outer Perimeter + Inner Perimeter = 40 + 16 = 56 inches

Answer:

[tex]P = 56\sqrt2[/tex]

Step-by-step explanation:

We can find the perimeter of a square given its diagonal by modeling the square as two congruent right triangles and using the Pythagorean Theorem to solve for the square's side lengths.

The Pythagorean Theorem states that...

[tex]a^2+b^2=c^2[/tex], where [tex]a[/tex] and [tex]b[/tex] are the right triangles legs, and [tex]c[/tex] is its hypotenuse.

However, since we are working with a square, we know that the right triangles' legs are congruent. Thus, the theorem becomes:

[tex]a^2 + a^2 = c^2[/tex]

[tex]2 \cdot a^2 = c^2[/tex]

Using this formula, we can solve for the square's side lengths, inputting the given hypotenuse length of 28.

[tex]2 \cdot a^2 = 28^2[/tex]

↓ simplify the exponent

[tex]2 \cdot a^2 = 784[/tex]

↓ divide both sides by 2

[tex]a^2 = 392[/tex]

↓ take the square root of both sides

[tex]a = \sqrt{392}[/tex]

↓ simplify the square root

[tex]a = \sqrt{2^3 \cdot 7^2}[/tex]

[tex]a = (2\cdot 7)\sqrt{2}[/tex]

[tex]a=14\sqrt2[/tex]

Finally, we can multiply the side length by 4 to get the square's perimeter (since a square has 4 sides).

[tex]P = 4 \cdot a[/tex]

[tex]P = 4 \cdot 14\sqrt2[/tex]

[tex]\boxed{P = 56\sqrt2}[/tex]

[tex]\boxed{P \approx 79.2}[/tex]

The cost per square inch of the apple pie is $ 0.16.

Given that,

The diameter of the pie = 10 in

The radius of the pie = 10/2

                             = 5 inches.

Area of the pie = [tex]\pi r^{2}[/tex]

The cost of the apple pie = $ 12.85.

Therefore, the cost per square inch of the pie = 12.85 ÷ 78.5

                                                                             = $ 0.16.
