x= ~28

Answer:

28˚

Step-by-step explanation:

1) In first triangle, x = 65

So, It is isosceles triangle.

2) In second triangle, x = 60

So, It is not isosceles triangle.

3) In third triangle, x = 45

So, It is not isosceles triangle.

4) In fourth triangle, x = 65

So, It is not isosceles triangle.

In first triangle,

Let measure of third angle = x

Hence,

x + 50 + 65 = 180

x + 115 = 180

x = 180 - 115

x = 65

So, It is isosceles triangle.

In second triangle,

Let measure of third angle = x

Hence,

x + 60 + 60 = 180

x + 120 = 180

x = 180 - 120

x = 60

So, It is not isosceles triangle.

In third triangle,

Let measure of third angle = x

Hence,

x + 70 + 65 = 180

x + 135 = 180

x = 180 - 135

x = 45

So, It is not isosceles triangle.

In fourth triangle,

Let measure of third angle = x

Hence,

x + 55 + 60 = 180

x + 115 = 180

x = 180 - 115

x = 65

So, It is not isosceles triangle.

Check the picture below.

so the way I see it, we have a bunch of semicircies going from 0 to 5, and we're looking at the bottom of the object, the provided picture above is not very useful btw.

so we're looking at the bottom of the object and the semicircles are going from 0 to 5, however from 0 to 1 they vary, from small to large, then they reach a diameter of 6 and go steady with that 6 all the way to 5.

so we can say that from 1 to 5, we can simply get the integral of a semicircle with a steady radius of 3, in which case that'd be the fixed value of 4.5π for the area.

now, we can also say that from 0 to 1 it varies, now, the radius varies, the radius is really the vertical value of the line or namely the y-value of that slanted line from 0 to 1, anyhow, not to bore you to death, but if we use the points (0 , 0) and (1 , 3) to get the equation of the line, we end up with y = 3x, and that's our radius, and we'll get the integral of those semicircles from 0 to 1 with a radius of 3x, with an area of 4.5πx²

The sample of 25 people interviewed by the sportswriter is not a Random sample. The correct answer is Option C. No, because not all residents of Columbus, Ohio have an equal chance of being selected.  

In statistics, sampling is the process of selecting a subset of individuals or units from a larger population to estimate or infer information about the population.

A random sample is a subset of individuals or units from a larger population that is selected in a way that every member of the population has an equal chance of being selected. In other words, a random sample is unbiased and represents the population as a whole.

In the given scenario, the sportswriter interviews the first 25 people who enter the stadium before a game in Columbus, Ohio to determine how strongly Columbus residents support building a new stadium for the local minor league baseball team.

Now, the question is whether this sample is a random sample or not.

The answer is "No, because not all residents of Columbus, Ohio have an equal chance of being selected," which is option C.

The reason is that the sportswriter only interviews the first 25 people who enter the stadium before the game. This means that the sample is not selected randomly from the entire population of Columbus residents, but only from the people who happened to be at the stadium at that particular time.

Moreover, people who attend minor league baseball games may not be representative of the entire population of Columbus residents. For example, people who attend baseball games may be more likely to support building a new stadium than those who do not attend such games.

Therefore, the sample of 25 people interviewed by the sportswriter is not a random sample and may not be representative of the entire population of Columbus, Ohio. The results of the survey based on this sample may not accurately reflect the opinions of all Columbus residents.

If we find that the null hypothesis, H_0 : B_j = 0, cannot be rejected when testing the contribution of an individual regressor variable to the model, we usually should 1. remove the variable from the model.

This is because if the variable is not contributing significantly to the model, it is not useful in predicting the outcome. Therefore, removing the variable will simplify the model and potentially improve its accuracy.
Options 2 and 3 (doing nothing or adding a quadratic term in x) would not be appropriate if the variable is not significant, as they would not address the issue of the variable's lack of contribution.
Option 4 is also incorrect because we do need to take action if a variable is not contributing significantly to the model.

To find the numbers "a" and "c" such that Norman scored lower than approximately "percent" of people who took the test, we need to use the standard normal distribution.

First, we calculate the z-score for Norman's score using the formula:

z = (x - mean) / standard deviation

In this case, x = 72, mean = 50, and standard deviation = 20.

z = (72 - 50) / 20 = 1.1

Next, we find the percentile corresponding to the z-score of 1.1 using a standard normal distribution table or a calculator. Let's assume it is "percent".

To find "c", we need to calculate the complement of "percent" and convert it to a decimal:

complement = 1 - (percent / 100)

Finally, to find "a", we use the formula:

a = mean + (c * standard deviation)

a = 50 + (complement * 20)

100c a can be obtained by multiplying "a" by 100.

Therefore, 100c a = 100 * a.

Please provide the value of "percent" to calculate the exact values for "c" and "100c a".

Step-by-step explanation:

the range is from the bottom line to top

the IQR is the length of the box in the middle

C. The range is 37 and the IQR is 20.

The range is the difference between the highest and lowest values in the data set. In this case, the highest value is 50 and the lowest value is 13, so the range is 50 - 13 = 37.

The interquartile range (IQR) is the difference between the first and third quartiles. In this case, the first quartile is 24 and the third quartile is 44, so the IQR is 44 - 24 = 20.

Therefore, the range is 37 and the IQR is 20 which is option c.

The expression that gives the simplified expression for the value of f'(1) is option D) lim0 (3h + 7), which evaluates to 9. The function f(x) can be written as f(x) = 3x^3.

To find f'(x), we need to take the derivative of f(x) with respect to x. Using the power rule of differentiation, we get:

f'(x) = 9x^2

To find the value of f'(1), we substitute x = 1 in the expression for f'(x):

f'(1) = 9(1)^2 = 9

Now, we need to find the expression that gives the simplified expression for the limit of the difference quotient, which is the definition of the derivative. The difference quotient is given by:

[f(x + h) - f(x)] / h

Substituting f(x) = 3x^3, we get:

[f(x + h) - f(x)] / h = [3(x + h)^3 - 3x^3] / h

Expanding the cube, we get:

[f(x + h) - f(x)] / h = [3(x^3 + 3x^2h + 3xh^2 + h^3) - 3x^3] / h

Canceling out the terms and simplifying, we get:

[f(x + h) - f(x)] / h = 9x^2 + 9xh + 3h^2

Now, we need to find the expression that gives the simplified expression for the limit of the difference quotient as h approaches 0. We can simplify the expression above as follows:

[f(x + h) - f(x)] / h = 9x^2 + 9xh + 3h^2
= 9x^2 + (9xh + 3h^2)
= 9x^2 + 3h(3x + h)

As h approaches 0, the second term in the expression above approaches 0. Therefore, the simplified expression for the limit of the difference quotient is:

lim(h → 0) [f(x + h) - f(x)] / h = 9x^2

Substituting x = 1, we get:

lim(h → 0) [f(1 + h) - f(1)] / h = 9(1)^2 = 9

The values of x, y and z for the right triangle are: x = √6, y = 3, and z = √10 respectively.

The perpendicular height of the right triangle divides the triangle in two triangles with the same proportions as the original triangle.

√15/(y + 2) = y/√15 {opposite/adjacent}

y(y + 2) = (√15)² {cross multiplication}

y² + 2y = 15

y² + 2y - 15 = 0

by factorization;

(y - 3)(y + 5) = 0

y = 3 or y = -5

by Pythagoras rule:

(√15)² = x² + y²

15 = x² + 3²

x = √(15 - 9)

x = √6

z² = (√6)² + 2²

z = √(6 + 4)

z = √10

Step-by-step explanation:

Part A: A histogram would be the best type of graphic to use to depict the supplied data.

The distribution of quantitative data (in this case, the frequency of sandwich consumption) is presented by a histogram, which enables us to see the frequency of various values or ranges. When working with discrete data, as in this instance, it is quite helpful.

Part B: Making a histogram using the provided data

To divide the data set into appropriate intervals or bins, ascertain the range of values covered by the data set (from the least to the maximum value). In this instance, a minimum value of 6 and a maximum value of 30 are acceptable starting points. Based on the distribution of the data, pick an acceptable bin width, such as 5 or 10. Indicate "Number of times a sandwich was eaten" on the horizontal axis and "Frequency" (or "Count") on the vertical axis.

The height of each bar should represent the frequency of values falling within each interval or bin, and the bars should be created for each interval/bin on the horizontal axis.

The height of each bar should represent the frequency of values falling within each interval or bin, and the bars should be created for each interval/bin on the horizontal axis. Counting the number of data points in each bin will yield the frequency.

Due to the fact that each interval is continuous and the values are discrete, make sure the bars are next to one another without any gaps.

Give the histogram a suitable title, like "Frequency Distribution of Sandwich Consumption."

Include a scale on the vertical axis if necessary to make the frequency count obvious.

These instructions will help you generate a histogram that accurately depicts the provided data and shows how frequently sandwiches were consumed by eighth-graders over the course of a 30-day period.

The correct option is option 5: monetary policy affects interest rates but no change in investment spending results when the LM-curve is vertical.

The LM curve represents the relationship between the interest rate and the level of income or output in an economy, assuming a fixed money supply. When the LM curve is vertical, it means that the central bank has fixed the money supply and is targeting a specific interest rate. In this case, changes in income or output do not affect the interest rate.

Option 1 is incorrect because the monetary policy multiplier can still be nonzero even when the LM curve is vertical. The multiplier refers to the effect of changes in monetary policy on income or output, and it depends on other factors such as the slope of the aggregate demand curve.

Option 2 is incorrect because when the LM curve is vertical, fiscal policy does not have a maximum effect on income. Fiscal policy refers to the use of government spending and taxation to influence the level of economic activity. In this case, changes in fiscal policy would not have a significant impact on income because the interest rate is fixed.

Option 3 is incorrect because when the LM curve is vertical, monetary policy has no effect on income. Fiscal policy would also have limited effectiveness since changes in government spending or taxation would not have a significant impact on interest rates.

Option 4 is incorrect because fiscal policy's impact on interest rates can still affect investment even when the LM curve is vertical. When fiscal policy influences interest rates, it can affect the cost of borrowing and, consequently, investment decisions.

Picard's theorem states that a first-order ordinary differential equation of the form y' = f(x, y) with an initial condition y(x0) = y0 has a unique solution if the function f(x, y) is continuous and satisfies the Lipschitz condition with respect to y in some region containing the initial point (x0, y0).

For the given differential equations, we can apply Picard's theorem to determine whether they have unique solutions.

(i) The function f(x, y) = t cos^-1(y) is continuous and satisfies the Lipschitz condition with respect to y in some neighborhood of (0, 1), so by Picard's theorem, the equation has a unique solution.

(ii) The function f(x, y) = tx is continuous and satisfies the Lipschitz condition with respect to y in some neighborhood of (0, y0), so by Picard's theorem, the equation has a unique solution.

(iii) The function f(x, y) = 1/(t^2*y^2) is not continuous at (0, 0), so we cannot apply Picard's theorem to determine whether the equation has a unique solution.

To determine the level of service of the four-lane freeway, we need to consider the geometric design, traffic volume, vehicle mix, and the presence of ramps and obstructions. The HCM methodology can be used to estimate the level of service based on various parameters.

To determine the level of service of the four-lane freeway, we need to consider several factors, including the geometric design, traffic volume, vehicle mix, and the presence of ramps and obstructions.

First, the four-lane freeway has two lanes in each direction with 12-ft lanes, and obstructions 3 ft from the right edge of the traveled pavement. This geometric design may affect the traffic flow, especially when heavy vehicles and RVs are present. These types of vehicles require more space to maneuver, and the presence of obstructions may limit their ability to do so.

Second, the directional weekday peak-hour volume of 2100 vehicles is observed. This traffic volume is relatively high and may lead to congestion and delay, especially during peak hours. To estimate the level of service, we need to use the Highway Capacity Manual (HCM) methodology, which considers various parameters such as speed, travel time, and density.

Third, we need to account for the vehicle mix, which includes 5% heavy vehicles and 10% RVs. These types of vehicles have different characteristics than passenger cars and may affect the traffic flow differently. For example, heavy vehicles may cause more congestion due to their slower speed and larger size, while RVs may require more space to maneuver and may have limited visibility.

Finally, we need to consider the presence of ramps within 2 miles upstream and 2 miles downstream of the midpoint of the analysis segment. Ramps can affect the traffic flow by adding or removing vehicles from the mainline, and their location and design can affect the merging and weaving maneuvers.

The product is 476(cos 540° + i sin 540°).

To find the product and write it in rectangular form, let's simplify the expression step by step.

First, let's simplify the expressions within each set of brackets separately:

Step 1: [4(cos 60° + i sin 60°)I7(cos 210° + i sin 210°)]

This expression involves multiplying two complex numbers using the polar form. When multiplying complex numbers, we multiply their magnitudes and add their angles.

The magnitude of 4 is 4, and the magnitude of I7 is 7. The angle of cos 60° + i sin 60° is 60°, and the angle of cos 210° + i sin 210° is 210°.

Therefore, the product of the first set of brackets is:

4 * 7 * (cos (60° + 210°) + i sin (60° + 210°))

= 28 * (cos 270° + i sin 270°)

= 28 * (-i)

= -28i

Step 2: [4(cos 60° + i sin 60°)17(cos 210° + i sin 210°)]

Similarly, we multiply the magnitudes and add the angles:

4 * 17 * (cos (60° + 210°) + i sin (60° + 210°))

= 68 * (cos 270° + i sin 270°)

= 68 * (-i)

= -68i

Now, we multiply the two results from the above steps:

(-28i) * (-68i)

= (-28 * -68) * (i * i)

= 1904 * (-1)

= -1904

So, the product of the given expression is -1904.

In rectangular form, a complex number is represented as a + bi, where a is the real part and b is the imaginary part.

Hence, the product in rectangular form is -1904 + 0i, or simply -1904.

It addresses a parameter and not a statistic. Hypotheses about parameters are common in statistical analysis as they allow us to make inferences and draw conclusions about the population based on sample data. Thus, the statement H: σ > 110 is a legitimate statistical hypothesis.

Therefore, option A is correct.
