Answer:

Step-by-step explanation:

The number of minutes spent higher than 38 meters above the ground on the Ferris wheel ride is approximately 1.0918 minutes.

To solve this problem, we need to determine the angular position of the Ferris wheel when it is 38 meters above the ground.

The Ferris wheel has a diameter of 50 meters, which means its radius is half of that, or 25 meters.

When the Ferris wheel is at its highest point, the radius and the height from the ground are aligned, forming a right triangle.

The height of this right triangle is the sum of the radius (25 meters) and the platform height (4 meters), which equals 29 meters.

To find the angle at which the Ferris wheel is 38 meters above the ground, we can use the inverse sine (arcsine) function.

The formula is:

θ = arcsin(h / r)

where θ is the angle in radians, h is the height above the ground (38 meters), and r is the radius of the Ferris wheel (25 meters).

θ = arcsin(38 / 29) ≈ 1.0918 radians

Now, we know the angle at which the Ferris wheel is 38 meters above the ground.

To calculate the time spent higher than 38 meters, we need to find the fraction of the total revolution that corresponds to this angle.

The Ferris wheel completes one full revolution in 2 minutes, which is equivalent to 2π radians.

Therefore, the fraction of the revolution corresponding to an angle of 1.0918 radians is:

Fraction = θ / (2π) ≈ 1.0918 / (2π)

Finally, we can calculate the time spent higher than 38 meters by multiplying the fraction of the revolution by the total time for one revolution:

Time = Fraction \(\times\) Total time per revolution = (1.0918 / (2π)) \(\times\) 2 minutes

Calculating this expression will give us the answer in minutes.

Answer:

The answer would be 540,000

543,982 to the nearest ten thousandth place would be 540,000.

Key Information:

2=ones place

8=tens place

9=hundreds place

3=thousands place

4=ten thousands place

5=hundred thousands place

Based on this information, the digit "4" would be in the ten thousandths place.

So, from the ten thousandths place, we can take 43,982.

Take the digit "3" in the thousandths place and round it.

Ask a question. Is the digit "3" closer to 0 or 10? It is closer to 0.

So, this means that 43,982 rounds to 40,000, not 50,000.

Then, you just add the digit "5" initially from the hundred thousandths place. This is where you will get 540,000.

So, therefore, the final answer is that 543,982 rounds to 540,000.

Hope this helped answer your question for you. Good day to you.

Answer: c. estimated OLS values are not BLUE

Step-by-step explanation:

Regression of ordinary least squares (OLS) is a statistical analysis technique that estimates the relationship between one or more independent variables and a dependent variable. The method estimates the relationship between the observed and predicted values of the relationship by minimizing the sum of the squares.

There are 8 to take Lara and Hayden to volunteer the same number.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Lara already volunteered 50 hours and will volunteer 5 hours more each week.

And, Hayden already volunteered to 10 hours and will volunteer 10 hours each week .

Now, For Lara;

⇒ 50 + 5x

And, For Hayden;

⇒ 10 + 10x

So, For same number of volunteer is,

⇒ 50 + 5x = 10 + 10x

⇒ 50 - 10 = 10x - 5x

⇒ 40 = 5x

⇒ x = 40/5

⇒ x = 8

Thus, There are 8 to take Lara and Hayden to volunteer the same number.

Answer:

x = -7

Step-by-step explanation:

All vertical lines have the form x = a number

All horizontal lines have the form y = a number . We can see in the points given the both the x's are -7 (You can also graph them and see the vertical line) So you have a vertical line in the form x = -7

Using the same-side interior angles theorem,

\(8x+30+6x+24=180 \\ \\ 14x+54=180 \\ \\ 14x=126 \\ \\ \boxed{x=9}\)

Using vertical angles,

\(6(9)+24=10y+2 \\ \\ 78=10y+2 \\ \\ 10y=76 \\ \\ \boxed{y=7.6}\)

Given that,

\(f(x) = {x}^{2} \)

\(g(x) = x - 1\)

Solution:

Solving for (f•g)(x):

\( = f(x) \cdot g(x)\)

Now substitute the given values.

\( = x {}^{2} \cdot(x - 1)\)

\( = x {}^{2} (x - 1)\)

Apply distributive property:

\( = (x ^{2} \cdot x) - x {}^{2} \cdot 1\)

Hence,f•g(x) will be \( x {}^{3} - x {}^{2}\).

Answer: 8.6

Step-by-step explanation:

The square root of 74 cannot be simplified, but its decimal form is 8.6.

The solution set of this inequality is {x| x > -6.1}

Here we have the inequality:

2x + 8 > -4.2

To find the solution set, we need to isolate the variable x in one of the sides of the inequality. Doing that we will get:

2x + 8 > -4.2

2x > -4.2 - 8

2x > -12.2

x > -12.2/2

x > -6.1

So the set of all numbers larger than -6.1, this in number form is:

{x| x > -6.1}

Answer:

I'm not 100% sure, so I really apologize if my answer is incorrect (Haven't done interest rate in a while) But the answer I got was $161.64

Step-by-step explanation:

The time taken by Amy to travel to the place was t = 4 hours.

A measure of average speed is the amount of distance travelled in a given amount of time. It is determined by dividing the overall mileage by the overall time required to cover that mileage.

In physics and other sciences, average speed is frequently employed to describe how objects move. For instance, it is possible to estimate how long it will take to go a certain distance or assess a car's fuel economy by looking at its average speed over a given distance. By dividing the whole distance travelled by the total time required, average speed may also be used to characterise the speed of an object that is moving at various speeds at different points along its path.

Let the time taken to get back = t + 1.

Now, it took one hour less time to get there thus time = t.

Now, average speed is given as:

average speed = total distance / total time

Substituting the values:

50 km/h = d / t

d = 50t  .........(1)

40 km/h = d / (t + 1)

d = 40(t + 1)......(2)

Setting the value of d as equal we have:

50t = 40(t + 1)

50t = 40t + 40

10t = 40

t = 4

Hence, the time taken by Amy to travel to the place was t = 4 hours.

Answer:

C

Step-by-step explanation:

For these types of problems, its important that we focus on the base as well as the lengths of the base and any other given lengths.

Here, the net has a base that forms a square with side lengths of 8mm.

So automatically, we can eliminate choices a and d as both have a base that is a triangle rather than a square.

We've also noticed that the base has a length of 8mm

If we look at B and C closely, we can tell that B has base lengths of 10mm while C has base lengths of 8mm.

So C is the correct answer choice.

Answer:

A) P(chooses a blue pencil and then a red pencil) = 5/27

B) P(chooses yellow then blue) = 5/81

Step-by-step explanation:

She has 3 red pencils, 5 blue pencils, and 1 yellow pencil in her backpack

Thus;

total number of pencils = 3 + 5 + 1 = 9 pencils

A) probability that she chooses a blue pencil and then a red pencil;

P(blue) = 5/9

Now she puts it bag after choosing which means the sum is back to 8 pencils.

Thus, if she now chooses a red pencil, then P(red) = 3/9 = 1/3

Thus;

P(chooses a blue pencil and then a red pencil) = 5/9 × 1/3

P(chooses a blue pencil and then a red pencil) = 5/27

B) probability that Chloe chooses the yellow pencil and then a blue pencil;

Similar to A above;

P(yellow) = 1/9

P(blue) = 5/9

P(chooses yellow then blue) = 1/9 × 5/9

P(chooses yellow then blue) = 5/81

A linear equation can have one or more variables.

A linear equation of one variable is represented as:

\(Ax + B = C\)

Where

A linear equation of two variables is represented as:

\(y = mx + b\)

Where

There are several ways to solve a linear equation; one of these ways is by using the distributive property of equality.

The distributive property of equality states that:

\(a(b + c) = ab + ac\)

Now; for example

\(3(x + 1) = 2\)

The first step is to distribute the left-hand side, as follows

\(3 \times x + 3 \times 1 = 2\)

Then you evaluate all products

\(3x + 3 = 2\)

Apply subtraction property of equality

\(3x +3 - 3= 2 -3\)

\(3x = -1\)

Apply division property of equality

\(\frac{3x}3 = -\frac 13\)

\(x = -\frac 13\)

Hence, the value of x for \(3(x + 1) = 2\) is \(-\frac 13\)

perimeter is 220m

Answer:

Step-by-step explanation:

The distance around the field means the perimeter of the field

Since the field is rectangular

Perimeter of a rectangle = 2l + 2w

where l is the length

w is the width

l = 85m

w = 25m

Perimeter = 2(85) + 2(25)

Perimeter = 170 + 50
