Answer:

19320 kg/m³

Step-by-step explanation:

We are given that the density of gold is 19.32 g/cm³, and we want to convert that density to kg/m³.

We can solve this in a manner similar to dimensional analysis, which is common in chemistry. When we do dimensional analysis, we use conversion factors with labels that we cancel out in order to get to the labels that we want.

Recall that 1 kg is 1000 g, and 1 m³ is cm. These will be our conversion factors.

So, we can do the following:

\(\frac{19.32g}{1 cm^3} * \frac{1000000 cm^3}{1 m^3} * \frac{1kg}{1000g}\) = 19320 kg/m³

So, the density of gold is 19320 kg/m³.

The measure of tangent angle QIA is 180 degrees.

m/QIA = 180 degrees.

If IA is the diameter of the circle, it means that angle QIA is a right angle (90 degrees). Since QN is tangent to the circle at point I, it is perpendicular to the radius IA at that point.

Therefore, in triangle QIA, we have a right angle at Q and a right angle at I. This implies that angle IQA is also 90 degrees.

In a right triangle, the sum of the angles is 180 degrees. Since angles QIA and IQA are both right angles, the remaining angle in the triangle, angle QAI, must be:

180 degrees - 90 degrees - 90 degrees = 0 degrees

Angle QAI is a degenerate angle, which means it has a measure of 0 degrees. Therefore, the measure of tangent angle QIA is 180 degrees.

To summarize, m/QIA = 180 degrees.

The Bonferroni method is a procedure for controlling the family-wise error rate (FWER) in multiple comparisons.

To use the Bonferroni method to perform multiple comparisons of the four levels of treatments at the 0.01 level, we would do the following:

Determine the number of pairwise comparisons that will be made. In this case, there are 6 possible pairwise comparisons among the 4 levels of treatments: (1,2), (1,3), (1,4), (2,3), (2,4), and (3,4).

Calculate the Bonferroni-corrected significance level for each pairwise comparison by dividing the desired overall significance level (0.01) by the number of pairwise comparisons. In this case, the Bonferroni-corrected significance level for each pairwise comparison is:

0.01 / 6 = 0.00167

Conduct each pairwise comparison using the Bonferroni-corrected significance level. For example, to compare treatment levels 1 and 2, we would conduct a hypothesis test at the 0.00167 level of significance. If the p-value for the test is less than 0.00167, we would reject the null hypothesis and conclude that there is a significant difference between treatment levels 1 and 2. We would repeat this process for each pairwise comparison.

Note that the Bonferroni method is a conservative approach, meaning that it tends to be more stringent than other methods of controlling the FWER. This can reduce the likelihood of false positives (Type I errors) but may also increase the likelihood of false negatives (Type II errors).

The value of tSTAT is 4.08. The slope of the regression line tells us the rate at which Y changes for each unit increase in X.

tSTAT stands for "t statistic". t statistic is a parameter that estimates how far a sample mean is likely to be from the population mean. A t-test is used to determine whether a difference between two groups is significant. The formula for calculating the t-statistic is:tSTAT = (b1 - 0) / Sb1Where b1 is the slope of the regression line, Sb1 is the standard error of the slope, and 0 is the hypothesized value of the slope (which is zero when testing for no linear relationship between two variables, X and Y).In this case, b1 = 5.3, Sb1 = 1.3, and 0 = 0. Therefore:tSTAT = (5.3 - 0) / 1.3 = 4.08Thus, the value of tSTAT is 4.08.

In statistics, the t statistic is a ratio between the difference between the sample mean and the null hypothesis and the standard error of the mean. The null hypothesis in this case is that there is no linear relationship between two variables, X and Y. The t-test is used to determine whether this null hypothesis is true or not.In order to calculate the t statistic, we need to know the slope of the regression line (b1) and the standard error of the slope (Sb1).  The standard error of the slope tells us how much variation there is in the slope estimate from sample to sample.The formula for calculating the t statistic is:tSTAT = (b1 - 0) / Sb1Where b1 is the slope of the regression line, Sb1 is the standard error of the slope, and 0 is the hypothesized value of the slope (which is zero when testing for no linear relationship between two variables, X and Y).In this case, b1 = 5.3, Sb1 = 1.3, and 0 = 0. Therefore:tSTAT = (5.3 - 0) / 1.3 = 4.08.Thus, the value of tSTAT is 4.08.

Answer:

\(T_{10} - T_7 = 112\)

Step-by-step explanation:

Given

\(T_9 = 63\)

Required

Find \(T_{10} - T_7\)

From the question, we have that:

Each sequence = 2 * Previous sequence + 1;

i.e.

\(T_n = 2 * T_{n - 1} + 1\)

Considering the 9th sequence;

\(T_9 = 2 * T_8 + 1\) ------ Equation 1

Considering the 8th sequence;

\(T_8 = 2 * T_7 + 1\)

Substitute \(2 * T_7 + 1\) for \(T_8\) in equation 1

\(T_9 = 2 * T_8 + 1\) becomes

\(T_9 = 2 * (2 * T_7 + 1) + 1\)

Open bracket

\(T_9 = 2 * 2 * T_7 + 2*1 + 1\)

\(T_9 = 4T_7 + 2 + 1\)

\(T_9 = 4T_7 + 3\)

Substitute 63 for \(T_9\)

\(63 = 4T_7 + 3\)

Subtract 3 from both sides

\(63 - 3 = 4T_3 + 3 - 3\)

\(60 = 4T_3\)

Divide both sides by 4

\(\frac{60}{4} = \frac{4T_3}{4}\)

\(15 = T_7\)

\(T_7 = 15\)

Considering \(T_{10}\)

\(T_1_0 = 2 * T_9 + 1\)

Substitute 63 for \(T_9\)

\(T_1_0 = 2 * 63 + 1\)

\(T_1_0 = 126 + 1\)

\(T_1_0 = 127\)

Calculating \(T_{10} - T_7\)

\(T_{10} - T_7 = 127 - 15\)

\(T_{10} - T_7 = 112\)

Hence, the 10th - 7th number is 112

Answer:

∠ BAC = 32°

Step-by-step explanation:

Supplementary angles sum to 180° , then

∠ BAC = 180 - (18x + 22) = 180 - 18x - 22 = 158 - 18x

Complementary angles sum to 90° , then

∠ BAC = 90 - (9x - 5) = 90 - 9x + 5 = 95 - 9x

Now equate the 2 expressions for ∠ BAC

95 - 9x = 158 - 18x ( add 18x to both sides )

95 + 9x = 158 ( subtract 95 from both sides )

9x = 63 ( divide both sides by 9 )

x = 7

Substitute into either of the 2 expressions for ∠ BAC

∠ BAC = 95 - 9x = 95 - 9(7) = 95 - 63 = 32°

To calculate the energy of the resulting explosion when a 10,000 kg UFO made of antimatter crashes with a 40,000 kg plane made of matter, we can use Einstein's famous equation, E=mc², which relates energy (E) to mass (m) and the speed of light (c).

In this case, we'll need to calculate the total mass of matter and antimatter involved in the collision and then use the equation to find the energy released. The equation E=mc² states that energy is equal to the mass multiplied by the square of the speed of light (c). In this scenario, we have a collision between a UFO made of antimatter and a plane made of matter. Antimatter and matter annihilate each other when they come into contact, resulting in a release of energy.

To calculate the energy of the resulting explosion, we need to determine the total mass involved in the collision. The total mass can be calculated by adding the masses of the UFO and the plane together. In this case, the UFO has a mass of 10,000 kg and the plane has a mass of 40,000 kg, so the total mass is 50,000 kg.

Next, we can use the equation E=mc² to calculate the energy. The speed of light (c) is a constant value, approximately 3 x 10^8 meters per second. Plugging in the values, we have E = (50,000 kg) x (3 x 10^8 m/s)². Simplifying the equation, we have E = 50,000 kg x 9 x 10^16 m²/s².Multiplying the numbers, we get E = 4.5 x 10^21 joules. Therefore, the energy of the resulting explosion when the UFO and plane collide is approximately 4.5 x 10^21 joules.

The population density in Nevada in 2012 was approximately 24.9 people per square mile.

In order to find the population density in Nevada in 2012, we need to know the land area of Nevada in square miles. Assuming the land area of Nevada in 2012 was 110,622 square miles, we can calculate the population density as follows:

First, we need to find the population of Nevada in 2012:

Population in 2012 = Population in 2005 + (Population in 2005 x % increase)

Population in 2012 = 2.432 million + (2.432 million x 0.132)

Population in 2012 = 2.754944 million (rounded to the nearest thousand)

Next, we can calculate the population density:

Population density = Population / Land area

Population density = 2.754944 million / 110,622 square miles

Population density ≈ 24.9 people per square mile

Therefore, the population density in Nevada in 2012 was approximately 24.9 people per square mile.

Given, the function is f(x,y,z)=5+yxz+g(x,z)Here, we need to find the directional derivative of f at the point (3,0,3) along the direction of the vector (0,4,0) . The directional derivative of f at the point (3,0,3) along the direction of the vector (0,4,0) is 0.

Using the formula of the directional derivative, the directional derivative of f at the point (3,0,3) along the direction of the vector (0,4,0) is given by

(f(x,y,z)) = grad(f(x,y,z)).v

where grad(f(x,y,z)) is the gradient of the function f(x,y,z) and v is the direction vector.

∴ grad(f(x,y,z)) = (fx, fy, fz)

                       = (∂f/∂x, ∂f/∂y, ∂f/∂z)

Hence, fx = ∂f/∂x = 0 + yzg′(x,z)fy

                = ∂f/∂y

                = xz and

fz = ∂f/∂z = yx + g′(x,z)

We need to evaluate the gradient at the point (3,0,3), then

we have:fx(3,0,3) = yzg′(3,3)fy(3,0,3)

                             = 3(0) = 0fz(3,0,3)

                             = 0 + g′(3,3)

                             = g′(3,3)

Therefore, grad(f(x,y,z))(3,0,3) = (0, 0, g′(3,3))Dv(f(x,y,z))(3,0,3)

                                                 = grad(f(x,y,z))(3,0,3)⋅v

where, v = (0,4,0)Thus, Dv(f(x,y,z))(3,0,3) = (0, 0, g′(3,3))⋅(0,4,0)   = 0
