c = 30 inch

Step-by-step explanation:

perpendicular (p) = 18 inch

base(b) = 24 inch

hypotenuse (h) = ?

we know by using Pythagoras theorem

h² = p² + b²

h² = 18² + 24²

h² = 324 + 576

h² = 900

h= √900

therefore h = 30 inch

Answer: The plane has flown 5,183 feet (approximately)

Step-by-step explanation: First and foremost, the plane is at vertex B of a right angled triangle ABC, and angle A measures 10°. Also the vertical side BC is the distance covered by the plane which in this case is the hypotenuse. The line BC is facing angle A which is the reference angle, hence line BC is the opposite.

With this bit of information we can calculate the distabce flown (hypotenuse) as follows;

Sin A = opposite ÷ hypotenuse

Sin 10 = 900/c

By cross multiplication we now have;

c = 900/Sin 10

c = 900/0.17364817766693

c = 5182.89

c ≈ 5183

Therefore the plane has flown 5,183 feet (approximately)

To find the distance the plane has flown, use the cotangent of the given angle (10 degrees) and multiply with the opposite side length (900 feet). The resulting value, rounded to the nearest foot, is the distance flown.

In this scenario, we have a right triangle where it's given that the vertical side BC = 900 feet, the angle at A is 10 degrees, and we need to find the length of the hypotenuse AB (distance the plane has flown). For a right triangle, the trigonometric property that relates the angle with the sides is tangent (tan), defined as the ratio of the opposite side to the adjacent side.

However, in this case, we need to use its reciprocal function, cotangent (cot), which gives the ratio of the adjacent side to the opposite side. As we know the opposite side (900 feet) and the angle (10 degrees), we can find the length of the hypotenuse (AB) using the cotangent of the angle, i.e., cot(10 degrees) = AB/900. So, AB = cot(10 degrees) * 900.

On calculating the above expression and rounding to the nearest foot, you get the distance the plane has flown.

Answer:

v=2571.13667 mm^3

Step-by-step explanation:

A marble is a sphere, and the volume of a sphere can be found using:

[tex]v=\frac{4}{3} \pi r^3[/tex]

We need to find the radius, and we know that the radius is 1/2 of the diameter

r=d/2

r=17/2

r=8.5

Now we can substitute 8.5 in for r, and 3.14 in for pi

[tex]v=\frac{4}{3} (3.14)(8.5^3)[/tex]

[tex]v=\frac{4}{3} (3.14)(614.125)[/tex]

[tex]v=\frac{4}{3}(1928.3525)[/tex]

[tex]v=2571.13667 mm^3[/tex]

The volume of a glass marble with a diameter of 17 mm is approximately 2600 mm³ (2.6 cm³) when computed using the formula V = (4/3) πr³ and 3.14 as the value for π, with the final result rounded to two significant figures.

To calculate the volume of a glass marble with a diameter of 17 millimeters using 3.14 as the value of π (pi), we use the formula for the volume of a sphere, which is V = (4/3) πr³.

First, we need to find the radius of the marble, which is half the diameter. The diameter is 17 mm, so the radius is 17 mm ÷ 2 = 8.5 mm. Substituting the radius into the volume formula, we get V = (4/3) × 3.14 × (8.5 mm)³.

Calculating the radius to the third power, (8.5 mm)³ = 614.125 mm³. Multiply this by 3.14: 614.125 mm³ × 3.14 = 1928.3525 mm³. Then multiply by 4/3: × (4/3) = 2571.1367 mm³. Since the measured value of volume is limited by the number of significant figures, we need to round this to two significant digits. Therefore, the approximate volume of the marble is 2600 mm³ (2.6 cm³) after rounding off. Please note that the measured value of 17 mm only has two significant figures, so the final answer must also reflect this limitation.

If 3/10 of the project was completed in 9 days, then the total project takes 30 days to complete. Therefore, it will take 21 more days to finish the remaining work.

The given problem involves a basic understanding of ratios and proportions, specifically applied to the concept of time and work. We know from the problem that 3/10 of the work was completed in 9 days. If that amount of work represents 3/10, then 1 whole or the complete work would be (10/3) times that much. We can set up the proportion as follows: 3/10 = 9/x. Solving for x gives us x = (10/3) * 9 = 30 days. So, at the same rate of work, it will take 30 days to complete the project. However, since 9 days of work have already been done, the project can be finished in 30 - 9 = 21 more days.

The area of a square given its radius is [tex]144 cm^2[/tex]

To find the area of a square when given the radius of a circle inscribed in the square, we need to use the diameter of the circle, which is twice the radius, to determine the side length of the square.

The radius provided in this question is 6 cm.

The area of a square can be found using the formula: [tex]A = side^2.[/tex]

In this case, since we're given the radius, we need to calculate the side length first, which is 2 * radius.

Therefore, side length = 2 * 6 cm = 12 cm.

Now, calculate the area: A = 12 cm * 12 cm = [tex]144 cm^2[/tex]

Answer: It’s 4 they’re all wrong (pretty sure I have the same graph)

Step-by-step explanation:

A general cosine function has the form:

f(x) = A*cos(c + x)

We want to find the value of A that matches the one in the image, and we will find that A = 3

Ok, a general cosine function is:

f(x) = A*cos(c + x)

Where A is the amplitude.

To find the amplitude of a cosine function, we just need to find half of the difference between the maximum and minimum value of the function:

By looking at the given graph, we can see that the maximum is y = 3, and the minimum is y = -3

Then the amplitude is:

A = (3 - (-3))/2 = 6/2 = 3

Step-by-step explanation:

It is a right angled triangle so with reference angle 37°

hypotenuse (b) = 10

perpendicular (p) = x

So

tan 37° = p/ b

0.75 = x / 10

x= 0.75/10

Therefore x = 0.075

Hope it will help you :)

The value of x when rounded to nearest 10th will be 6.0

Given: a right angled triangle with hypotenuse equal to 10 units and angle opposite to the perpendicular equal to 37°

To find: value of the perpendicular [tex]x[/tex]

To find the perpendicular we can use trigonometric equation:

[tex]\sin \theta = \frac{\text{perpendicular}}{\text{hypotenuse}}[/tex]

where [tex]\theta[/tex] is the angle opposite to the perpendicular

Putting the values in the equation we get:

[tex]\sin 37 = \frac{x}{10}\\[/tex]

[tex]0.6018 = \frac{x}{10}\\[/tex]

[tex]x= 0.6018 \times 10\\x = 6.018[/tex]

So, the value of the perpendicular (x) is 6.018 units but when rounded to nearest 10th we get 6.0

Answer: The margin of error is larger in the 90% CI than in the 80% CI.

Step-by-step explanation:

Confidence interval is written as

Sample mean ± margin of error

Margin of error = z × population standard deviation/number of samples

The z score for a 90% confidence level(1.645) is higher than the z score for a 80% confidence level(1.282)

If all other parameters(sample size and population standard deviation) remain the same, then the true statement is

The margin of error is larger in the 90% CI than in the 80% CI.

Option(A) The margin of error is larger in the 90% confidence interval than in the 80% CI because as the confidence level increases, a wider interval is required to maintain more certainty that it encompasses the true population parameter.

If we take samples from normal populations and construct two confidence intervals (CI) for which the only difference is that one of them is at the 80% confidence level and the other is at the 90% confidence level, the margin of error is larger in the 90% CI than in the 80% CI. This is because the margin of error (EBM) depends on the confidence level. A higher confidence level requires a wider interval to ensure that it captures the true population parameter with more certainty.

To construct a confidence interval, we use the form (point estimate − margin of error, point estimate + margin of error), where the margin of error depends on the confidence level and the standard error of the mean. Thus, as the confidence level increases from 80% to 90%, the margin of error needs to increase as well, resulting in a wider interval. This can be observed by comparing the 90 percent confidence interval to a 99 percent confidence interval, where the latter is wider because it leaves out less of the distribution in the tails and hence contains more of the normal distribution's probability.
