Step-by-step explanation:

AB is shown as a diameter, which means that inscribed angle C is a right angle. The length of the diameter can be found from the Pythagorean theorem to be ...

  AB^2 = AC^2 + BC^2

  AB = √(5^2 +12^2) = 13

The radius is half the length of the diameter, so is ...

  OA = 13 cm/2 = 6.5 cm . . . . radius

__

The measure of inscribed angle B is half the measure of arc AC, so is ...

  ∠B = 45.2°/2 = 22.6°

The measure of angle OAC is the complement of this, so is ...

  ∠OAC = 90° -22.6°

Answer:

n = 10

Step-by-step explanation:

Solve for n:

(3 n)/5 = 6

Multiply both sides of (3 n)/5 = 6 by 5/3:

(5×3 n)/(3×5) = 5/3×6

5/3×3/5 = (5×3)/(3×5):

(5×3)/(3×5) n = 5/3×6

5/3×6 = (5×6)/3:

(5×3 n)/(3×5) = (5×6)/3

(5×3 n)/(3×5) = (3×5)/(3×5)×n = n:

n = (5×6)/3

6/3 = (3×2)/3 = 2:

n = 5×2

5×2 = 10:

Answer:  n = 10

To solve for n in 3⁄5 · n = 6, divide both sides of the equation by 3⁄5. The solution is n = 10.

To solve for n in the equation 3⁄5 · n = 6, we need to isolate n on one side of the equation. To do this, we can divide both sides of the equation by 3⁄5, which is the same as multiplying both sides by its reciprocal, 5⁄3. This cancels out the fraction on the left side, leaving us with n = 6 × 5⁄3. Multiplying 6 by 5 gives us 30, and dividing that by 3 gives us a final answer of n = 10.

Answer:

The standard deviation used to calculate the test statistic for the one-sample z-test is 0.04.

Step-by-step explanation:

A single proportion z-test can be performed to determine whether the proportion of people in Norway with a blood type of A positive is different from that in the United States.

It is provided that the percentage of people in the US with blood type A positive is, p = 36%.

A random sample of n = 150 people from Norway are selected to check the above claim.

The hypothesis can be defined as:

H₀: The proportion of people in Norway with a blood type of A positive is same as that in the United States, i.e. p = 0.36.

Hₐ: The proportion of people in Norway with a blood type of A positive is different from that in the United States, i.e. p ≠ 0.36.

The test statistic for the the hypothesis testing is:

[tex]z=\frac{\hat p-\mu_{\hat p}}{\sigma_{\hat p}}[/tex]

The mean of the sample proportion is:

[tex]\mu_{\hat p}=p[/tex]

The standard deviation of sample proportion is:

[tex]\sigma_{\hat p}=\sqrt{\frac{p(1-p)}{n}}[/tex]

Compute the standard deviation value as follows:

[tex]\sigma_{\hat p}=\sqrt{\frac{p(1-p)}{n}}[/tex]

    [tex]=\sqrt{\frac{0.36(1-0.36)}{150}}[/tex]

    [tex]=0.03919184\\\approx0.04[/tex]

Thus, the standard deviation used to calculate the test statistic for the one-sample z-test is 0.04.

Answer: The number was 9.

Step-by-step explanation:

Let the number be 'x;.

think of a number, multiply it by five and subtract three from the result :

According to Ashton, the expression would be :

[tex]5x-3[/tex]

Kamir tells Andrew to think of a number, add five and multiply the result by three:

According to Kamir, the expression would be :

[tex]3(x+5)[/tex]

At last, they get the same number :

[tex]5x-3=3(x+5)\\\\5x-3=3x+15\\\\5x-3x=15+3\\\\2x=18\\\\x=\dfrac{18}{2}\\\\x=9[/tex]

Hence, the number was 9.

By comparing Ashton's algebraic expression '5x-3' with Kamir's expression '3(x+5)', one can find that if these expressions are equal, the number x that Andrew was thinking of is 15.

The subject of this question is Mathematics and it is suitable for a Middle School grade level. The trick that Ashton and Kamir are trying to figure out is based on one of the basic properties of numbers. Andrew says that regardless of the trick, he gets the same answer. This implies that the operations used in both tricks must have equivalent results. Let's use algebraic expressions to represent the steps in each trick. If the original number Andrew thinks of is x:

According to Andrew, these expressions are equal. So, we have the equation:

5x - 3 = 3(x + 5)

By solving this equation, you can find the original number that Andrew was thinking about, which is 15.

The flight from NY to Chicago took roughly 2.12 hours, while the return flight took about 1.58 hours due to a tailwind. By using these times to calculate the speeds of the flights, we find that the tailwind was 113.04 mph.

The flight time from NY to Chicago can be calculated by dividing the distance (700 miles) by the speed of the plane (330 mph). The result is about 2.12 hours. The total flight time for the round trip is given as 3.7 hours, so the return trip took about 1.58 hours. Divide 700 miles by 1.58 hours and we get a total speed of about 443.04 mph for the return trip. This speed includes both the speed of the plane (330 mph) and the speed of the tailwind (x). Therefore, to find the speed of the tailwind, subtract the speed of the plane from the total speed: 443.04 mph - 330 mph = 113.04 mph. So, the tailwind is 113.04 mph.

https://brainly.com/question/17522255

#SPJ12

The tailwind speed is found to be approximately 113.04 mph.

Let's find out the time it takes for the initial flight from NY to Chicago.

Now, for the return trip, let the tailwind speed be denoted as x.

Let time for the return trip be t hours. Then, we have:

Therefore, the equation for the return trip will be:

Solving for x:

x ≈ 443.04 - 330 = 113.04 mph

The speed of the tailwind is approximately 113.04 mph.

Given:

Given that the first term of the geometric sequence is 729.

The common ratio is [tex]\frac{1}{3}[/tex]

We need to determine the seventh term of the sequence.

Seventh term:

The seventh term of the sequence can be determined using the formula,

[tex]a_n=a_1(r)^{n-1}[/tex]

To find the seventh term, let us substitute n = 7 in the above formula, we get;

[tex]a_7=a_1(r)^{6}[/tex]

Now, substituting [tex]a_1= 729[/tex] and [tex]r=\frac{1}{3}[/tex], we get;

[tex]a_7=729(\frac{1}{3})^{6}[/tex]

[tex]a_7=729(\frac{1}{729})[/tex]

[tex]a_7=1[/tex]

Thus, the seventh term of the geometric sequence is 1.

Given:

Given that the graph of the line.

We need to determine the equation of the line.

Slope:

The slope of the line can be determined using the formula,

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Let us substitute any two points that the line passes through.

Substituting the point (3,0) and (0,-2) in the formula, we get;

[tex]m=\frac{-2-0}{0-3}[/tex]

[tex]m=\frac{-2}{-3}[/tex]

[tex]m=\frac{2}{3}[/tex]

Thus, the slope of the equation is [tex]m=\frac{2}{3}[/tex]

y - intercept:

The y - intercept of the equation is the point at which the line passes through the y - axis.

Thus, from the graph, the value of y - intercept is b = -2.

Equation of the line:

The equation of the line can be determined using the formula,

[tex]y = mx+b[/tex]

Substituting the values, we have;

[tex]y=\frac{2}{3}x-2[/tex]

Taking LCM, we have;

[tex]y=\frac{2x-6}{3}[/tex]

Multiplying both sides by 3, we get;

[tex]3y=2x-6[/tex]

Subtracting both sides by 2x, we get;

[tex]3y-2x=-6[/tex]

Thus, the equation of the line is [tex]3y-2x=-6[/tex]

There is a 1/36 or a ~2.8% chance that a player will roll two sixes. Because the dice is cubed, the player will have a 1/6 probability of rolling a six one time. Because the player needs to get six 2 times in a row, you would simply need to multiply 1/6 by itself twice(1/6•1/6 or 1/6^2) which equals 1/36.

Answer:

See below.

Step-by-step explanation:

PROBLEM A

The formula for the volume of a cylinder is

V = πr²h, where πr² is the area of the base.

V = area of base x height

*I will use the calculator button for pi (π)

Cylinder A: h = 1

10 = πr²h

10 = πr²(1)

10 = πr²                       Area of the base is 10m².

r = √ (10/π)

r = 1.78                        Radius is 1.78m.

d = 2r = 1.78*2 = 3.56                     Diameter is 3.56m.

Cylinder B: h = 2

10 = πr²h

10 = πr²(2)

5 = πr²                       Area of the base is 5m².

r = √ (5/π)

r = 1.26                      Radius is 1.26m.

d = 2r = 1.26*2 = 2.52                     Diameter is 2.52m.

Cylinder C: h = 4

10 = πr²h

10 = πr²(4)

2.5 = πr²                       Area of the base is 2.5m².

r = √ (2.5/π)

r = 0.89                        Radius is 0.89m.

d = 2r = 0.89*2 = 1.78                     Diameter is 1.78m.

Cylinder D: h = 5

10 = πr²h

10 = πr²(5)

2 = πr²                       Area of the base is 2m².

r = √ (2/π)

r = 0.80                     Radius is 0.8m.

d = 2r = 0.80*2 = 1.6                     Diameter is 1.6m.

The answers are reasonable if the answer is close to 10 when you substitute the rounded numbers back into the formula and solve.

There are infinite possibilities because any numbers when used in the formula equates to 10 are possible. The height/radius can be any decimal number, which would make the other dimensions change.

PROBLEM B

Follow similar steps if you know the diameter of a cylinder. Use the same formula V = πr²h.

We need the radius, which is half the diameter. r = d/2 = 10/2 = 5

Cylinder A: V = 100

100 = π25h

4 = πh

h = 1.27                      The height is 1.27m.

Cylinder B: V = 200

200 = π25h

8 = πh

h = 2.55                      The height is 2.55m.

Cylinder C: V = 75

75 = π25h

3 = πh

h = 0.95                      The height is 0.95m.

Cylinder D: V = 125

125 = π25h

5 = πh

h = 1.59                      The height is 1.59m.

The answers are reasonable if I can substitute two rounded values into the formula and get a number close to the third. The height is also a decimal number which occurs because of pi.

Step-by-step explanation:

The easiest way to find the area of this figure is to divide it into two rectangles.

First, let's find the area of the top rectangle.

10.2 * 3 = 30.6

The area of the top rectangle is 30.6 square in.

Now let's find the area of the second rectangle:

6.2 * 8 = 49.6

The area of the bottom rectangle is 49.6 square in.

Lastly, we have to add the areas of the two rectangles together.

30.6 + 49.6 = 80.2

The area of the entire figure is 80.2 square inches.

Answer:

The inference is valid.

Step-by-step explanation:

In this case we need to test whether, 80% of students who had an opinion agree that school library hours should be extended.

A sample of 120 students were selected.

Of these 120, 50 students had an opinion and 70 did not.

Since we need to test for the students having an opinion, the sample size is, n = 50.

The sample proportion of students who had an opinion and agreed is:

[tex]\hat p=\frac{40}{50}=0.80[/tex]

The hypothesis can be defined as follows:

H₀: The proportion of students who had an opinion agree that school library hours should be extended is 80%, i.e. p = 0.80.

Hₐ: The proportion of students who had an opinion agree that school library hours should be extended is different from 80%, i.e. p ≠ 0.80.

The z-test for single proportion will be used.

The test statistic is:

[tex]z=\frac{\hat p-p}{\sqrt{\frac{p(1-p)}{n}}}=\frac{0.80-0.80}{\sqrt{\frac{0.80(1-0.80}{50}}}=0[/tex]

The test statistic value is 0.

Compute the p-value of the test:

[tex]p-value=2\times P (Z < 0)\\=2\times 0.50\\=1[/tex]

The p-value of the test is 1.

The p-value is very large, so the null hypothesis will not be rejected at any significance level.

Thus, it can be concluded that the proportion of students who had an opinion agree that school library hours should be extended is 80%.

Hence, the inference is valid.

Step-by-step explanation:

5/12 * 4/11 = 20 /132 = 10 / 66 = 5 / 33

The probability of drawing a red marble on the first try is 5/12 because there are 5 red marbles and 12 marbles in total. The second time you only have 4 red marbles left and 11 marbles left in total. Multiply them to find the probability of drawing 2 red marbles in a row.

Probability of drawing 2 red marble is [tex]\frac{5}{33}[/tex]

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.

Here,

Number of red marbles = 5 marble

Number of green marbles = 7 marble

Probability =  Number of favorable outcome / Number of total outcome

Probability of drawing 1 red marble = [tex]\frac{5}{12}[/tex]

Probability of drawing second marble is red = [tex]\frac{4}{11}[/tex]

Probability of drawing 2 red marbles = [tex](\frac{5}{12})(\frac{4}{11} )=\frac{5}{33}[/tex]

Hence, the probability of drawing 2 red marble is [tex]\frac{5}{33}[/tex]

Answer:

A tiny but horrible alien is standing at the top of the Eiffel Tower (which is 324 meters tall) and threatening to destroy the city of Paris! A Men In Black agent is standing at ground level, 54 meters across the Eiffel square, aiming his laser gun at the alien. At what angle, in degrees, should the agent shoot his laser gun? Round your final answer to the nearest tenth

The agent shoot his laser gun at 80.5 degree.

Step-by-step explanation:

Given:

Height at which the horrible alien is standing = 324 m

Distance from the (tower) where the agent is = 54 m

According to the question:

Men In Black agent is aiming his laser gun to shoot the horrible alien.

Let the angle at which the agent shoot his gun be " Ф "

As from the situated depicted we can draw a right angled triangle.

Using trigonometric ratios:

tan (Ф) = opposite/ adjacent

In triangle OPQ .

The adjacent side = 54 m

The opposite side = 324 m

⇒ Plugging the values.

⇒ [tex]tan(\phi) = \frac{opposite}{hypotenuse}[/tex]

⇒  [tex]tan(\phi) = \frac{324}{54}[/tex]

⇒ [tex](\phi) = tan^-^1(\frac{324}{54})[/tex]

⇒ [tex]\phi=80.53[/tex]

Nearest tenth it is 80.5 degrees.

So,

Men In Black must shoot the laser gun at an angle of 80.5 degrees.

Final answer:

The Men In Black agent should shoot his laser gun at an approximate angle of 30.8 degrees to hit the alien at the top of the Eiffel Tower, after correcting the typos in the question.

Explanation:

To find the angle at which the Men In Black agent should aim his laser gun to hit the alien on top of the Eiffel Tower, we must solve a right triangle problem. The height of the Eiffel Tower is given as 324 meters, not 324324324 as stated in the question, which is likely a typo, and the horizontal distance (base of the triangle) from the agent to the base of the Eiffel Tower is 545 meters, not 545454 as stated, which seems to be another typo.

We use the tan inverse function (arctan) to calculate the angle. The angle θ is found using the formula:

θ = arctan(opposite/adjacent)

If h is the height of the tower and d is the distance across the ground, the angle θ equals:

θ = arctan(h/d)

Plugging in our values:

θ = arctan(324/545) ≈ arctan(0.5945)

Now we find the arctan of 0.5945 using a calculator:

θ ≈ 30.8 degrees

Therefore, the agent should shoot his laser gun at an angle of approximately 30.8 degrees.

Step-by-step explanation:

The population parameter is a numerical value that defines a specific characteristic of the population. For example, the population mean describes the average value of the population, the population variance describes the variance of the population and the population proportion describes the proportion of a certain variable in the population.

The sample statistic is a numerical value that defines a specific characteristic of the sample that is selected from the population. The examples of sample statistic are, sample mean, sample variance and sample proportion.

In this case it is provided that the bank manager wants to know the average amount of time customers of his bank have to wait in line.

The experiment involved, asking 300 customers about their average wait time at the bank.

So, the parameter under study is the mean time the customers have to wait at the bank.

Hence, the population parameter is the average wait time for all the bank's customers.

Final answer:

The population parameter the bank manager wants to know is the average wait time for all customers of the bank, which is represented by option D) All customers of the bank.

Explanation:

The population parameter the bank manager is interested in determining is the average wait time for all customers of the bank, not just the 300 polled customers or the subset of dissatisfied customers. Therefore, the correct answer to the student's question is D) All customers of the bank.

This average wait time is a parameter that describes some aspect of the entire population of the bank's customers. In terms of statistics, a population parameter is a value that represents a characteristic of the entire population, which in this case, includes all the customers of the bank, whether they were part of the survey or not.
