lines a and b are parallel in the diagram what is the measure of angle 1
Answers
Answer:
45
Step-by-step explanation:
Upon examining the graph, you can realize that angle 3x is the same as the angle directly to the left of 9x. Since that makes a straight line, we can realize that that sums up to 180. We call this a linear pair.
so you have:
3x+9x = 12x = 180
x = 15
A important concept to know here is vertical angles. Vertical angles occur when two lines intersect each other. The opposite angles formed at an intersection are congruent, which is why 1 is congruent to 3x.
Therefore, angle 1 is 45 degrees.

Picture below answers your question.
10) A submarine starts on the surface, and dives at an angle of depression of 13° from the surface. It goes
diagonally a distance of 890 meters before reaching the bottom. How deep is the water where the submarin
reaches the bottom? (Drawing 1 pt, distance 1.5 pts, units .5 pt)
890
Answers
The water where the submarine reaches the bottom is approximately 212.43 meters deep.
To determine the depth of the water where the submarine reaches the bottom, we can use trigonometry.
The angle of depression of 13° tells us that the submarine is diving at an angle below the horizontal line.
The distance traveled diagonally, which is 890 meters, represents the hypotenuse of a right triangle.
Using trigonometric functions, we can find the length of the adjacent side, which represents the depth of the water.
In this case, we can use the tangent function:
tan(13°) = opposite/adjacent
We know the opposite side is the depth we're trying to find, and the adjacent side is the distance traveled diagonally.
Solving for the depth:
\(depth = 890 \times tan(13) \approx 212.43 meters\).

Answers
Answer:
\(x=32768.000\)
Step-by-step explanation:
One is given the following expression:
\(log_2(x)+log_4(x)=5\)
Use the logarithm base change rule, which states the following:
\(log_b(y)=\frac{log(y)}{log(b)}\)
Remember, a logarithm with not base indicated is another way of writing a logarithm to the base of (10). One can apply the base change rule to this situation:
\(log_2(x)+log_4(x)=5\)
\(\frac{log(x)}{log(2)}+\frac{log(x)}{log(4)}=5\)
Factor out (log(x)),
\((log(x))(\frac{1}{log(2)}+\frac{1}{log(4)})=5\)
Inverse operations:
\(log(x)=\frac{5}{\frac{1}{(log(2)+log(4)}}\)
Simplify,
\(log(x)=5(log(2)+log(4))\)
\(log(x)=4.51545\)
Now rewrite the logarithm, remember, a logarithm is another way of writing an exponent, in the following format:
\(b^x=y\ \ -> log_b(y)=x\)
\(log(x)=4.51545\)
\(10^4^.^5^1^5^4^5=x\)
\(32768.000=x\)

Suppose you wish to measure the impact of smoking on the weight of newborns. You are planning to use the following model, log(bw i
)=β0+β1 male i
+β2 order i
+β3y i
+β4cig i
+ϵ i
where bw is the birth weight, male is a dummy variable assuming the value 1 if the baby is a boy or 0 otherwise, order is the birth order of the child, y is the log income of the family, cig is the amount of cigarettes per day smoked during pregnancy, i indexes the observation and the β 's are the unknown parameters. (a) What could be the problem in using OLS to estimate the above model? (b) Suppose you have data on the average price of cigarettes in the state of residence. Would this information help to identify the true parameters of the model? (c) Use data on BirthWeight.dta to estimate the model above. Use OLS and 2SLS. Discuss the results. (d) Estimate the reduced form for cig. Discuss
Answers
a) Using OLS to estimate the model may lead to biased and inconsistent results due to potential endogeneity.
b) Data on the average price of cigarettes in the state of residence, potentially help identify the true parameters of the model.
c) The 2SLS estimates would be more reliable and provide a better understanding of the true relationship between smoking and birth weight.
d) Estimating the reduced form for cig, we can assess the validity of the instrumental variable
(a) The problem with using Ordinary Least Squares (OLS) to estimate the above model is that the error term, εi, may be correlated with one or more of the explanatory variables. In this case, there might be endogeneity issues, where the variable cig (amount of cigarettes per day smoked during pregnancy) is likely to be correlated with the error term.
This violates one of the key assumptions of OLS, which is the absence of correlation between the error term and the explanatory variables.
(b) Having data on the average price of cigarettes in the state of residence could potentially help identify the true parameters of the model. This information can be used as an instrumental variable (IV) for the variable cig.
An instrumental variable is a variable that is correlated with the endogenous variable (cig) but is not correlated with the error term. By using an IV approach, such as 2SLS (Two-Stage Least Squares), we can obtain consistent estimates of the true parameters of the model, even in the presence of endogeneity.
(c) To estimate the model using OLS and 2SLS, you would need access to the data on birth weight (bw), male (dummy variable), order (birth order of the child), y (log income of the family), cig (amount of cigarettes per day smoked during pregnancy), and other relevant variables. OLS would provide estimates of the parameters under the assumption of no endogeneity
. However, 2SLS would be preferred in this case, as it addresses the potential endogeneity issue by using instrumental variables.
After estimating the model using both OLS and 2SLS, you should compare the results. If the OLS estimates are significantly different from the 2SLS estimates, it suggests the presence of endogeneity.
In this case, the 2SLS estimates would be more reliable and provide a better understanding of the true relationship between smoking and birth weight.
(d) To estimate the reduced form for cig, you would need to regress the variable cig on other exogenous variables that are not included in the main model. The reduced form would provide the relationship between the instrumental variable (average price of cigarettes) and cig. By estimating the reduced form, you can assess the validity of the instrumental variable and its relevance in addressing the endogeneity issue.

The radius of a dartboard is 9 inches What is the area of the dartboard in square inches?
Answers
the area of the dartboard is approximately 254.34 square inches.
The area of a dartboard can be calculated using the formula for the area of a circle, which is given by:
Area = π * \(radius^2\)
Given that the radius of the dartboard is 9 inches, we can substitute this value into the formula:
Area = π * \(9^2\)
Area = π * 81
To calculate the area, we need to use the value of π (pi). Pi is an irrational number and is commonly approximated as 3.14. Using this approximation, we can calculate the area:
Area ≈ 3.14 * 81

The equation of the degree 6 polynomial with a root at 3, a double root at 2, and a triple root at -1, and y-intercept at y = 5 is given as follows:
y = -5/12(x - 3)(x - 2)²(x + 1)³.
How to define the polynomial?The equation of the function is obtained considering the Factor Theorem, as a product of the linear factors of the function.
The zeros of the function, along with their multiplicities, are given as follows:
Zero at x = 3 with a multiplicity of 1.Zero at x = 2 with a multiplicity of 2.Zero at x = -1 with a multiplicity of 3.Then the linear factors of the function are given as follows:
(x - 3).(x - 2)².(x + 1)³.The function is then defined as:
y = a(x - 3)(x - 2)²(x + 1)³.
In which a is the leading coefficient.
When x = 0, y = 5, due to the y-intercept, hence the leading coefficient a is obtained as follows:
5 = -12a
a = -5/12
Hence the polynomial is:

if your study had an alpha value of 0.05 and a power of 80%, calculate the chance that you made a type ii error.
Answers
There is a 20% chance that you made a Type II error in your study with an alpha value of 0.05 and a power of 80%. This means that there is a 20% chance that you failed to detect a true effect or relationship in the population.
To calculate the chance of making a Type II error, we need to understand what Type II error is and how it relates to the alpha value and power of a study.
Type II error, also known as a false negative, occurs when we fail to reject the null hypothesis when it is actually false. In other words, it means we incorrectly conclude that there is no effect or relationship in the population, even though there is one.
The power of a study represents the probability of correctly rejecting the null hypothesis when it is indeed false. It is directly related to the probability of making a Type II error. Therefore, the chance of making a Type II error is equal to 1 minus the power of the study.
Given that the power of the study is 80% (or 0.80), the chance of making a Type II error can be calculated as follows:
Chance of making a Type II error = 1 - Power of the study
= 1 - 0.80
= 0.20 or 20%

As the degrees of freedom (DF) increase, the t distribution approaches the normal distribution. Therefore, the correct answer option is: C. normal distribution.
What is the degrees of freedom (DF)?The degrees of freedom (DF) in a sample are typically used to correct a possible bias that exists between the alternative and null hypotheses because they are the maximum number of logically independent numerical values (data points) in the final calculation of a statistical problem.
What is a normal distribution?A normal distribution is sometimes referred to as the Gaussian distribution and it can be defined as a probability distribution that is continuous and symmetrical on both sides of the mean, which shows that all data near the mean have a higher frequency than data that are far from the mean.

Here is a wheel with radius 1 foot. List three different counterclockwise angles the wheel can rotate so that point P ends up at position Q.
Answers
Three different counterclockwise angles obtained when wheel rotates such that point P ends up at position Q are: 90° , 180° and 270°.
Explain about the counterclockwise angles?The angle is positive if the rotation is anticlockwise. The angle is negative if the rotation is in the clockwise direction. Angles can be expressed in radians or degrees. Counterclockwise rotation produces positive angles.
Positive angles, then, represent the turn or rotation that is anticlockwise. Clockwise rotation results in negative angles. In other words, we must rotate clockwise to measure negative angles.
The wheel is rotated anti-clock wise from point P to Q.
So,
90° : (x,y) ------> (-y,x)180° : (x, y) ------> (-x,-y)270° : (x,y) ------> (y,-x)Thus, three different counterclockwise angles obtained when wheel rotates such that point P ends up at position Q are: 90° , 180° and 270°.
