Answer:

x degrees, 14x degrees, x degrees, 14x degrees, x degrees, 14x degrees, 2x degrees, and 28x degrees.

Step-by-step explanation:

The ratio of the same side interior angles of two parallel lines is 1:14, which means that for every one degree of the first angle, the second angle measures 14 degrees. If the first angle is x degrees, then the second angle is 14x degrees.

Since the lines are parallel and the angles are on the same side of the transversal, the alternate interior angles are congruent, so the measure of the third angle is also x degrees, and the measure of the fourth angle is also 14x degrees.

Since the lines are parallel, the alternate exterior angles are also congruent, so the measure of the fifth angle is also x degrees, and the measure of the sixth angle is also 14x degrees.

Finally, the measures of the seventh and eighth angles can be found by adding the measures of the adjacent angles. The seventh angle is adjacent to the third and fifth angles, so its measure is x + x = 2x degrees. The eighth angle is adjacent to the fourth and sixth angles, so its measure is 14x + 14x = 28x degrees.

In summary, the measures of the eight angles formed by the parallel lines and transversal are x degrees, 14x degrees, x degrees, 14x degrees, x degrees, 14x degrees, 2x degrees, and 28x degrees. The value of x can be determined by knowing the measure of one of the angles, or by using other information about the angles or the parallel lines.

The slope of a line in the form "y = mx + b" is given by the coefficient "m" of the x term.

For the first equation, x - 2y = -1/2, we can rearrange the terms to get y = (1/2)x - 1/2. The coefficient of the x term is 1/2, so the slope of the line is 1/2.

For the second equation, -4x - 8y = 2, we can rearrange the terms to get y = -(1/2)x - 1/4. The coefficient of the x term is -1/2, so the slope of the line is -1/2.

m∠C has a value of 47. The angle between any two of the triangle's three sides is known as an interior angle.

An internal angle is the angle inside a shape. A polygon is a closed shape with sides and vertices. A regular polygon's inner angles are all equal to one another. The internal angles of a square, for instance, are all exactly right angles, or 90 degrees. A triangle's three inside angles will always add up to 180 degrees. Since the other two angles (180°+0°+0°) would not exist, a triangle cannot have a single angle of 180°. On the same vertex, the internal angle and the external angle add up to radians (180°). The total internal angle of a simple polygon, where n is the number of sides, is (n2) radians, or 180(n-2) degrees.

Angle C from the statement is sharp. Remember that an acute angle is an angle that measures less than 90 degrees. Also, remember that the internal angles of any triangle add up to 180 degrees. Then:

m∠A +m∠B +m∠C =180

But

m∠A= 110

m∠B= 23

Substituting value:

110+23+m∠C =180

The solution of the DTDS is xn = (0.63)^n * 41 grams, where n represents time in hours.

a) The updating function f(x) for the discrete time dynamical system (DTDS) can be derived from the given information that the body eliminates 37% of the alcohol present in the body per hour.

Since 37% of the alcohol is eliminated, the amount remaining after one hour can be calculated by subtracting 37% of the current amount from the current amount. This can be expressed as:

f(x) = x - 0.37x

Simplifying the equation:

f(x) = 0.63x

b) The initial condition for the DTDS is given as Peter having 41 grams of alcohol in his body after consuming three alcoholic drinks. Therefore, the initial condition is:

x0 = 41 grams

c) To find the solution of the DTDS with the given initial condition, we can use the updating function f(x) and iterate it over time.

For n hours, the solution is given by:

xn = f^n(x0)

Applying the updating function f(x) repeatedly for n times:

xn = f(f(f(...f(x0))))

In this case, since the function f(x) is f(x) = 0.63x, the solution can be written as:

xn = (0.63)^n * x0

Substituting the initial condition x0 = 41 grams, the solution becomes:

xn = (0.63)^n * 41 grams

(6, -1)

Step-by-step explanation:

Solve the System of Equations

2x + 3y = 9 and x − 2y = 8

Add 2y to both sides of the equation.

x = 8 + 2y 2x + 3y = 9

Replace all occurrences of x with 8 + 2y in each e quation.

Replace all occurrences of x in 2x + 3y = 9 with 8 + 2y. 2 (8 + 2y) + 3y = 9

x = 8 + 2y

Simplify 2 (8 + 2y) + 3y.

16 + 7y = 9

x = 8 + 2y

Solve for y in the first equation.

Move all terms not containing y to the right side of the equation.

7y = −7

x = 8 + 2y

Divide each term by 7 and simplify.  

y = −1

x = 8 + 2y

Replace all occurrences of y with −1 in each equation.

Replace all occurrences of y in x = 8 + 2y with −1. x = 8 + 2 (−1)

y = −1

Simplify 8 + 2 (−1).

The amount that marcus end up paying for the two shirts originally priced  at $28.99 and $30.29 is given by: Option A: $39.59

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

\(\dfrac{a}{100} \times b\)

For this case, we're given that:

Cost of two shirts originally is $28.99 and $30.29

30% is off on each of them, so we get:

New price of each shirt = Old price of each shirt - 30% of old price of each shirt

New price of each shirt = \(28.99 - \dfrac{28.99}{100} \times 30\) and \(30.29- \dfrac{30.29}{100} \times 30\)

This sums up to $41.496

Now, at this price, there'd be application of 10% additional discount.

That will make the new price as:

\(41.496 - \dfrac{41.496}{100} \times 10 =37.3464\)

Now, on this price, there'd be applied 6% sales tax

So, the amount he paid for 2 shirts = discounted price + 6% tax on discounted amount

= \(37.3464 + \dfrac{37.3464}{100} \times 6 \approx 39.59 \: \rm dollars\)

Thus, the amount that marcus end up paying for the two shirts originally priced  at $28.99 and $30.29 is given by: Option A: $39.59

To estimate the percentage of people who weigh more than 190 pounds with a 98% confidence and an error no more than 3 percentage points, a minimum sample size of 1064 people should be surveyed.

To estimate the desired percentage accurately, we need to determine the necessary sample size for our survey. Given that body weights are normally distributed in the population, we can use the concept of a confidence interval to calculate the sample size required.

First, we need to determine the standard deviation of body weights in the population. This information is crucial in calculating the sample size. However, since the standard deviation is not provided in the question, we cannot determine the exact sample size. We will make an assumption based on typical body weight distributions.

Next, we can use the formula for sample size calculation:

n = (Z^2 * p * q) / E^2

Where:

- n is the required sample size

- Z is the z-value corresponding to the desired confidence level (98% confidence corresponds to a z-value of approximately 2.33)

- p is the estimated proportion of people who weigh more than 190 pounds

- q is 1 - p

- E is the desired margin of error, which is 3 percentage points (0.03 in decimal form)

Assuming a normally distributed population, we typically assume p = q = 0.5 to obtain the maximum sample size required. However, since we want to estimate the percentage of people weighing more than 190 pounds, p is likely to be less than 0.5.

Without the information on the proportion p, we cannot determine the exact sample size. However, based on typical distributions and assuming p = 0.5, we can estimate the minimum sample size required to be 1064 people.
