The interior angles of the trapezium is as follows:

∠P = 80°∠L = 100°∠N = 70°∠M = 110°

How to find the angle in a quadrilateral?

The sum of interior angles in a quadrilateral is 360 degrees. Therefore, the diagram above is a trapezium with 4 sides.

Let's find the measure of each interior angles

2x + 2x + 20 + 2x - 10 + 3x - 10 = 360

9x  = 360

divide both sides by 9

x = 360 / 9

x = 40

Therefore, each interior angles is as follows:

2x = 2(40) = 80 degrees

2x + 20 = 2(40) + 20 = 100 degrees

2x - 10 = 2(40) - 10 = 70 degrees

3x - 10 = 3(40) - 10 = 110 degrees

Answers

In a case whereby A ship travels due west for 94 miles. It then travels in a northwest direction for 119 miles and ends up 173 miles from its original position the degrees north of west it turned is 72°

How can the degree be calculated?

From trigonometry, the law of cosines states  the side c of a triangle can be found as

c² = a² + b² - 2abcos(C)

where

C = angle opposite to side c.

a and = lengths of the other sides.

a = 94, b = 119, c = 173.

c² = a² + b² - 2abcos(C)

173² = 94² + 119² - 2 x 94 x 119cos(C)

22327cos(C) = -6932

cos(C) = -6932/22327

C = arccos(-6932/22327)

C = 108º.

Then,

T = 180 - C

= 180 - 108 = 72º.

solution problem i am having trouble trying to solve or figure out

Answers

The solution to the System of equations is x = -9 and y = 8

We have the equation x - y = -1 and the equation x = -9. We can use the second equation to substitute the value of x in the first equation and solve for y.

Given x = -9, we substitute this value into the first equation:

(-9) - y = -1

Simplifying, we have:

-9 + y = -1

To isolate y, we can add 9 to both sides of the equation:

-9 + 9 + y = -1 + 9

This gives us:

y = 8

Therefore, the solution to the system of equations is x = -9 and y = 8.

We can check this solution by substituting the values of x and y back into the original equations:

Equation 1: x - y = -1

Substituting x = -9 and y = 8:

-9 - 8 = -1

Simplifying, we have:

-17 = -1

(c) A medical researcher is working on a new treatment for a certain type of cancer. The average survival time after diagnosis on the standard treatment is two years.

A. the calculation was in error. The researchers forgot to include the sample size.
B. the sample size is small.
C. the placebo effect is present, which limits statistical significance.
D. that although the survival time has doubled, in reality the actual increase is really two years.

Answers

a) The correct option is C. Construct a 99% confidence interval for μ in order to see the magnitude of the difference between 115 and your sample results.

b) The correct option is B. Use a very small level of significance.

c) The correct option is B. The sample size is small.

d) The lack of statistical significance at the 0.10 significance level suggests that the observed doubling of survival time may not be practically significant as the actual increase is only two years.

(a) To assess the practical significance of the results, the most helpful approach would be to construct a 99% confidence interval for the population mean, μ. This would provide a range of values within which the true population mean is likely to fall. By comparing this interval to the hypothesized value of 115, you can evaluate the magnitude of the difference and determine if it is practically significant.

Therefore, the correct option is C. Construct a 99% confidence interval for μ in order to see the magnitude of the difference between 115 and your sample results.

(b) When the consequences of rejecting the null hypothesis are very serious, it is important to be cautious and use a very small level of significance. The level of significance determines the threshold for rejecting the null hypothesis. By using a very small level of significance, you are setting a higher standard for rejecting the null hypothesis, reducing the likelihood of making a Type I error (false positive). This ensures that strong evidence is required to support rejecting the null hypothesis when the consequences are significant.

Therefore, the correct option is B. Use a very small level of significance.

(c) In this scenario, the explanation for the lack of statistical significance at the 0.10 significance level, despite the survival time doubling, is likely due to the small sample size. With only three subjects, the sample may not provide enough statistical power to detect a significant difference. The variability in survival times within the sample might also influence the lack of significance. A larger sample size would provide more reliable and statistically significant results.

Therefore, the correct option is B. The sample size is small.

d) The explanation for the lack of statistical significance in this scenario is that although the survival time has doubled from two years to four years, the actual increase is still only two years. This means that the difference between the standard treatment and the new treatment is not as substantial as it may initially seem.

When conducting statistical tests, it is important to consider both statistical significance and practical significance. While the survival time doubling may be a positive outcome, if the actual increase is only two years, it may not be considered practically significant in the context of cancer treatment.

Statistical significance is determined by conducting hypothesis tests and examining the p-value. In this case, even at the 0.10 significance level, the results are not statistically significant, indicating that the observed difference in survival times could likely be due to chance.

It is important to interpret the results in the context of the specific situation and consider factors such as sample size, variability, and clinical significance. In this case, the small sample size of three subjects may limit the statistical power to detect a significant difference. Additionally, the placebo effect or other factors may also play a role in limiting the statistical significance of the results.

In summary, the lack of statistical significance at the 0.10 significance level suggests that the observed doubling of survival time may not be practically significant as the actual increase is only two years.

The solutions of the given inequality is: x ≥ -1 or x ≤ -5, the correct number line is 2nd.

To solve the inequality |x + 3| ≥ 2, we need to consider two cases:

Case 1: (x + 3) ≥ 2

If x + 3 is greater than or equal to 2, then the absolute value of (x + 3) will also be greater than or equal to 2. Solving this case:

x + 3 ≥ 2

x ≥ 2 - 3

x ≥ -1

So, for this case, the solution is x ≥ -1.

Case 2: -(x + 3) ≥ 2

If -(x + 3) is greater than or equal to 2, then the opposite of (x + 3) will also be greater than or equal to 2. Solving this case:

-(x + 3) ≥ 2

x + 3 ≤ -2

x ≤ -2 - 3

x ≤ -5

So, for this case, the solution is x ≤ -5.

Combining the solutions from both cases, we have the final solution:

Answers

We are 98% confident that the true mean amount of money spent per month on home maintenance by all homeowners is between $70.19 and $75.81.

A confidence interval is a range of values that is likely to contain the true value of the population parameter with a given level of confidence. A confidence interval for the population mean μ can be constructed as follows:

μ = sample mean ± margin of error where the margin of error is given by:margin of error = (critical value) x (standard error)

Here, we want to construct a 98% confidence interval for the mean amount of money spent per month on home maintenance by all homeowners. We are given that a survey of 81 randomly selected homeowners finds that they spend a mean of $73 per month on home maintenance.

The population standard deviation is assumed to be $10 per month.

Therefore, the standard error of the mean is given by:standard error = σ / sqrt(n) = 10 / sqrt(81) = 10 / 9 = 1.11

where σ is the population standard deviation and n is the sample size.To find the critical value, we need to look up the t-distribution table with 80 degrees of freedom and a significance level of 0.01 (since we want a 98% confidence interval).

The corresponding value is 2.527.

Therefore, the margin of error is:margin of error = (critical value) x (standard error) = 2.527 x 1.11 = 2.81

Finally, we can construct the confidence interval as follows:73 ± 2.81 = (70.19, 75.81)The confidence interval is rounded to the nearest cent.

If Ole cuts out a piece of poster board that is exactly the same size as the window, which equation can be used to calculate the amount of poster board that will be left over?

Answers

The amount of poster board left over will be 1275 square inches, the equation used is  A = (b₁ + b₂)h/2.

To calculate the amount of poster board that will be left over after Ole cuts out a piece of poster board that is the same size as the window,

we need to find the area of the trapezoid window and subtract it from the area of the poster board.

The formula to find the area of a trapezoid is A = (b₁ + b₂)h/2, where b₁ and b₂ are the lengths of the parallel sides and h is the height.

Let's assume that the length of the top parallel side of the trapezoid is 20 inches, the length of the bottom parallel side is 10 inches, and the height is 15 inches.

Using the formula, we get A = (20 + 10) x 15 / 2 = 225 square inches. This is the area of the window.

To find the area of the poster board, we multiply the length and width, which gives 25 x 60 = 1500 square inches.

Finally, we subtract the area of the window from the area of the poster board using the equation:

1500 - 225 = 1275 square inches.

Therefore, the amount of poster board left over will be 1275 square inches.

Fergus and his best friend went to a movie
and bought popcorn. They split the cost
evenly, each paying $17. How much was the
total cost of the movie and popcorn? If x
equals the total cost, choose the equation
that solves the problem.
O x/2 = 17
Ox-17 = 2
Ox+17 = 2
2x = 17

Answers

Answer:

x / 2 = 17

Step-by-step explanation:

Since we're told that there are 2 friends, they split the cost evenly, and they  each paid $17 individually, we'd have to use the equation x / 2 = 17 to find the total cost.

If you were to solve, you'd find that the total cost was $34 as 2 * 17 = 34 and 34 / 2 = 17

You walk along the outside of a park starting at point P to point Q. You then take a shortcut back to point P, represented by PQ on the graph.

Answers

The length of the shortcut is 1 mile

The total length of your walk in the park is 1.4 miles

Given that you walk along the outside of a park starting at point P to point Q

The point P is at (0, 0)

The point Q is located at (0.6, 0.8)

We have to find the length of the shortcut

Distance=√(x₂-x₁)²+(y₂-y₁)²

PQ=√(0.6-0)²+(0.8)²

=√0.36+0.64

=√1 units

=1 mile

The total length of the park is PR+RQ

PR=√(0.6-0)²

=0.6

RQ==√(0.8-0)²

=0.8

The total length is 0.6+0.8

Which is 1.4 miles

Answers

The surface area of the rectangular prism is (26/3) times larger than the surface area of the cube.

Given data ,

Let the surface area of the cube be S₁

Let the surface area of the rectangular prism be S₂

Let the volume of the cube be V₁

Let the volume of the prism be V₂

On simplifying , we get

The side length of cube = x

So , surface area of cube = 6x²

The volume of cube = x³

And , the surface area of prism = 2 ( 12x² + 8x² + 6x² )

S₂ = 52x²

And , volume of prism = l x w x h

V₂ = ( 2x ) ( 3x ) ( 4x ) = 24x²

So , S₂ = ( 26/3 ) S₁

52x² = ( 26/3 ) ( 6x² )

52x² = 52x²

Hence , The rectangular prism's surface area is (26/3) times greater than the cube's surface area.

C = < 1, 15>.
Hallar: (A ∩ B ) - C

Answers

The result of the expression (A ∩ B) - C is [-2, 5] U [13, 18] is [-2,5,13,18].

To find the result of the expression (A ∩ B) - C, where A, B, and C are sets, we need to perform the following steps:

Find the intersection of sets A and B, denoted as (A ∩ B).Subtract set C from the intersection (A ∩ B).

Given the sets:

A = < - 7, 5 ] U [10, 18 >

B = [ - 2, 8 > U < 13, 23 >

C = < 1, 15 >

1.Find the intersection of sets A and B (A ∩ B):

To find the intersection, we need to find the overlapping region between the intervals.The intersection of the intervals [-7, 5] and [-2, 8] is [max(-7, -2), min(5, 8)] = [-2, 5].The intersection of the intervals [10, 18] and [13, 23] is [max(10, 13), min(18, 23)] = [13, 18].Therefore, the intersection of sets A and B is [-2, 5] U [13,18].

2. Subtract set C from the intersection (A ∩ B):

Subtracting set C = <1, 15> from the intersection [-2, 5] U [13, 18] means removing any elements that are present in set C from the intersection.

Since set C = <1, 15> does not overlap with either [-2, 5] or [13, 18], the subtraction (A ∩ B) - C results in the same set as the intersection:

(A ∩ B) - C = [-2, 5] U [13, 18].

The Martinez family has a large lot. They have decided to create a square garden in
one corner of the lot. They want to put a walkway around the garden. The walkway
will be 5 feet wide on one side of the square and 8 feet wide on the other side. The
total area of the garden and the walkway must be 700 square feet.p

Answers

The length of a side of the square garden is 5.75 feet.

How to calculate the length

(x+10)(x+5) - x² + (x+13)(x+8) - x² = 700

Simplifying and solving for x, we get:

2x^2 + 46x - 177 = 0

Using the quadratic formula, we can solve for x:

x = (-46 ± ✓46² - 4(2)(-177))) / (2(2))

x = (-46 ± 26) / 4

x = 5.75

The length of a side of the square garden is 5.75 feet.

B. 10 percent now and when she graduates.

C. 0 percent now and 10 percent when she graduates.

D. 12 percent now, 12 percent when she graduates.

Answers

Wendy's marginal tax brackets in 2022 while she is still in school is 12 percent and it will be also 12 percent when she graduates.

Hence the correct option is (D).

Given that Wendy is Single.

So the effective taxable income regime will be which is on the second column.

It is given that at her school days she earns a taxable income of $ 12,000.

So $12000 falls in the slab of $ 10276 - $ 41775.

So the tax rate for her in her school days is 12%.

When she will graduates the taxable per year income will be $35,000.

Clearly, $35,000 also falls into the slab of $ 10276 - $ 41775.

So the tax rate for her when she will graduate will be same 12 percent.

Hence the correct option will be (D).
