Answer:

A = 27π cm²

Step-by-step explanation:

Area of the shaded region = area of full circle of O - Area of the unshaded sector

= (πr²) - (θ/360*πr²)

Where,

r = 6 cm

θ = 360

Area of shaded region = (π*6²) - (90/360*π*6²)

= (36π) - (¼*π*36)

= 36π - 9π

Area of shaded region = 27π cm²

The length of GH is 15.

GH = IG

GH = 5x - 10

6th terms of given geometric progression whose common ratio is 3/2 and first term is 4  is 243/8 using the farmula ar^(n-1).

What is a geometric sequence?

A mathematical sequence known as a geometric progression (GP) is one in which each following phrase is generated by multiplying each preceding term by a fixed integer, or "common ratio." This progression is sometimes referred to as a pattern-following geometric sequence of numbers. Learn development in mathematics here as well. Here, each phrase is multiplied by the common ratio to generate the subsequent term, which is a non-zero value. A geometric series with a common ratio of 2 is 2, 4, 8, 16, 32, 64, etc.

Geometric Progression takes the following general form: a, ar, ar^2, ar^3, ar^4,..., ar^(n-1).

a = First term where

The common Ratio is r.

To find the radius of the spinner, we'll first find the total area of the spinner and then use the formula for the area of a circle. Radius is defined as the length between the center and the arc of circle.

Here are the steps:
1. Determine the proportion of the sectors that do not move the token: There are 3 such sectors (remaining sectors) out of a total of 9 sectors. So, the proportion is 3/9 = 1/3.

2. Calculate the total area of the spinner: Since 1/3 of the spinner has an area of 14.6 square inches, we can find the total area by multiplying the area of non-moving sectors by 3.
Total area = 14.6 * 3 = 43.8 square inches.

3. Use the formula for the area of a circle to find the radius: The formula for the area of a circle is A = πr^2, where A is the area and r is the radius. We'll solve for the radius (r) in this formula:
43.8 = πr^2

4. Divide both sides of the equation by π:
r^2 = 43.8 / π

5. Calculate r:
r = √(43.8 / π)

6. Round the result to the nearest tenth of an inch:
r ≈ 3.7 inches

So, the radius of the spinner is approximately 3.7 inches.

The point (-6, 9) is not a solution of the given system of equations. Therefore, (-6, 9) does not satisfy both equations simultaneously and is not a solution to the system.

To determine if the point (-6, 9) is a solution of the system of equations:

1. Substitute the values of x and y from the point (-6, 9) into each equation.

2. Check if both equations are satisfied when the values are substituted.

Equation 1: 6x + y = -27

Substituting x = -6 and y = 9:

6(-6) + 9 = -27

-36 + 9 = -27

-27 = -27

The first equation is satisfied.

Equation 2: 5x - y = -38

Substituting x = -6 and y = 9:

5(-6) - 9 = -38

-30 - 9 = -38

-39 = -38

The second equation is not satisfied.

Since the point (-6, 9) does not satisfy both equations simultaneously, it is not a solution of the system.

The correct statements about omitted variable bias are:

1. If the omitted variable and included variable are correlated, there is a bias.

2. If the omitted variable is relevant, there is a bias.

Omitted variable bias refers to the bias introduced in an econometric model when a relevant variable is left out of the analysis. The bias occurs when the omitted variable is correlated with both the dependent variable and the included variables in the model.

If the omitted variable and included variable are correlated, there is a bias because the included variable may capture some of the effects of the omitted variable. In this case, the estimated coefficient of the included variable will be biased, as it will include the influence of the omitted variable.

Similarly, if the omitted variable is relevant, there is a bias because it has a direct impact on the dependent variable. By excluding the relevant variable, the model fails to account for its influence, leading to biased estimates of the coefficients of the included variables.

Random assignment of included variables does not eliminate omitted variable bias. While random assignment may help control for confounding factors and reduce bias in certain experimental designs, it does not address the issue of omitting a relevant variable from the analysis. Omitted variable bias can still exist even with random assignment of included variables.

Answer:

the answer is y=1.25x

Step-by-step explanation:

The graph of g and f have equal intercepts while the slope of the graph of f is 5 times larger than the slope of the graph of g

Given: f(x) = 2x-6 and g(x)=5(0.2x)-6

To compare the two graphs, we can make use of the equation of a line:

The general form of the equation of a line is y = mx + c

Where m is the slope and c is the intercept

So we will compare two the functions with the equation of a line:

Comparing f(x) = 5x-6 with y = mx + c

The slope(m) of the line = 5 and the intercept(c) = -6

Also, comparing g(x) = 5(0.2x)-6 with y = mx + c

The slope(m) of the line = 5(0.2) = 1 and the intercept(c) = -6

Since the slope of f(x) = 5 and the slope of g(x) = 1. Thus:

slope of f(x) / slope of g(x)  = 5/1 = 5

So we can say the slope of  f(x) is  5 times the slope of g(x)

Therefore, the graph of g and f have the same intercept. But the slope of f(x) is  5 times the slope of g(x)

The test statistic for the relative percent differences in perceived life expectancy between men and women is -18.308, and the degrees of freedom for the test statistic are 12.

Let's calculate the test statistic, which is the mean of the relative percent differences for men and women combined:

Men: -28, -24, -21, -22, -15, -13

Women: -22, -20, -17, -9, -10, -11, -6

Combining the data:

-28, -24, -21, -22, -15, -13, -22, -20, -17, -9, -10, -11, -6

The mean of these values is (-28 - 24 - 21 - 22 - 15 - 13 - 22 - 20 - 17 - 9 - 10 - 11 - 6) / 13

= -18.308.

Next, we need to calculate the degrees of freedom for the test statistic. The degrees of freedom can be determined using the formula: df = n - 1, where n is the number of data points.

We have 13 data points, so the degrees of freedom are 13 - 1 = 12.

Therefore, the test statistic is -18.308 and the degrees of freedom are 12.

Our final answer is: 4.5726 x 10^0 (We use scientific notation to write the answer.) Significant figures refer to the accuracy of a measurement. They represent the number of digits in a value that are considered reliable or significant.

The rules for determining significant figures are as follows: All non-zero digits are considered significant.For example, in the number 243.1, there are four significant figures. All zeros between non-zero digits are considered significant.For example, in the number 402, there is only one significant figure.

All zeros to the right of a non-zero digit and to the right of the decimal point are significant.For example, in the number 5.00, there are three significant figures. All zeros to the left of the first non-zero digit are not significant.For example, in the number 0.0058, there are two significant figures.

Now, let's perform the calculations given in the question:(249.36 + 41.0) ÷ 63.498First, we'll add the numbers in the parentheses:249.36 + 41.0 = 290.36.

Now, we'll divide this sum by 63.498:290.36 ÷ 63.498 = 4.5725893 (This value has 8 digits, but we need to round it to the correct number of significant figures.) The given value has five significant figures, so our answer should also have five significant figures.

The digit in the fifth place is 5, which is greater than 5, so we round the digit in the fourth place up. Therefore, our final answer is: 4.5726 x 10^0 (We use scientific notation to write the answer.)

To find the vector v with initial point P and terminal point Q in component form, we subtract the coordinates of P from the coordinates of Q.

P = (-2, 3)

Q = (-5, -2)

To find v, we subtract the x-coordinate of P from the x-coordinate of Q and the y-coordinate of P from the y-coordinate of Q:

v = (Qx - Px, Qy - Py)
