If out of people who were chosen 3 out of 8 were chosen-again, then the ratio of people who were chosen twice is 3:10.

The "Ratio" is defined as a way of expressing the quantitative relationship between two or more quantities.

We know that, 40 people were selected and out of those 40 selected, 4 out of 5 were chosen, and

Out of the chosen people, 3 out of 8 were chosen again,

Now, we calculate the total-number of people who were chosen,

⇒ 40 selected × (4/5 chosen) = 32 people were chosen in the first round,

⇒ 32 chosen × (3/8 chosen again) = 12 people were chosen again in the second round.

So, the total number of people who were chosen twice is 12,

Now, we find ratio of people who were "chosen-twice" to "total-number-of-people" who were selected,

⇒ Ratio of people chosen twice to total people selected = 12/40,

On simplifying the ratio "12/40",

We get,

⇒ 12/40 = 3/10,

Therefore, the required ratio is 3:10.

So the two cars are approximately 13 kilometers apart.

The Pythagorean theorem is a fundamental concept in mathematics that describes the relationship between the sides of a right-angled triangle. It states that in any right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

Mathematically, the Pythagorean theorem can be expressed as:

c² = a² + b²

We can use the Pythagorean theorem to find the distance between the two cars, as they have traveled perpendicular to each other.

The horizontal distance between the two cars is 5 km, and the vertical distance is 12 km. Therefore, the distance between the two cars can be found using the Pythagorean theorem:

d² = 5² + 12²

d² = 25 + 144

d² = 169

d = √(169)

d = 13

So, the two cars are approximately 13 kilometers apart.

Answer:

m = 4

Y-intercept: 2

Step-by-step explanation:

8x + 4 = 2y

We rewrite the equation in slope-intercept form y = mx + b

m = the slope

b = y-intercept

8x + 4 = 2y

-2y + 8x + 4 = 0

-2y = -8x - 4

y = 4x + 2

m = 4

Y-intercept: 2

Rewriting the equation in slope-intercept form (y = mx + b) makes it easier to tell the slope and y-intercept. The rewritten form is y = 4x + 2. Since 'm' represents the slope, the slope of the equation is 4. 'b' represents the y-intercept, so the y-intercept is 2.

The cost of the concrete for these steps is approximately $14 to the nearest dollar.

What is meant by cost?

Cost is the amount of money or resources required to produce or obtain something. It includes the expenses incurred in the production or acquisition of goods or services.

What is meant by the dollar?

A dollar is a currency unit used in several countries, including the United States, Canada, Australia, and New Zealand. It is a standard unit of currency that represents a specific value and is used in financial transactions to buy goods and services.

According to the given information

The volume of one step is:

3 ft × 1.17 ft × 0.46 ft = 1.28 cubic feet

There are a total of 4 steps, so the total volume of concrete used for the steps is:

4 × 1.28 cubic feet = 5.12 cubic feet

Now that we know the volume of concrete used, we can find the cost by multiplying it by the cost per cubic foot:

5.12 cubic feet × $2.78 per cubic foot ≈ $14.26

Therefore, the cost of the concrete for these steps is approximately $14 to the nearest dollar.

Using the volume of the cylinder we know that 77% of the container B is full when the pumping is complete.

A cylinder is one of the most basic curvilinear geometric shapes and has traditionally been solid in three dimensions.

In elementary geometry, it is regarded as a prism with a circle as its basis.

A cylinder can instead be described as an infinitely curved surface in a number of modern domains of geometry and topology.

The following is a list of the cylinder's attributes: It has two flat circular faces, two curved edges, and one curved surface.

Its uniform cross-section throughout makes it resemble a prism.

They feature two bases that are circular, flat, and arranged in a straight line.

The resulting two-dimensional shape is a square with an area of 72 square units.

The pyramid is a square right pyramid, the base is a square and the vertical height meets the base at its center. When the pyramid is sliced by a plane that passes vertically through the top vertex and is perpendicular to the base, the resulting two-dimensional shape is a square.

The plane section intersects the four triangular faces of the pyramid, creating four smaller triangles with the same shape and size. These four triangles can be rearranged to form a smaller square that is similar to the larger square base of the pyramid. The area of the plane section is equal to the area of the smaller square, which is proportional to the area of the larger square base. The proportionality constant is equal to the ratio of the height of the plane section to the height of the pyramid.

Let H be the height of the pyramid and h be the height of the plane section. Then, we have:

h/H = (side length of smaller square)/(side length of larger square)

= √(2)/2

Solving for h, we get:

h = (√(2)/2) * H

The area of the plane section is then:

A = (side length of smaller square)²

= (√2)/2 * side length of larger square)²

= (√(2)/2)² * (side length of larger square)²

= (1/2) * (side length of larger square)²

Since the side length of the larger square base is given, we can substitute it in and simplify to get:

A = (1/2) * (12)² = 72 square units

As a result, the resultant two-dimensional form is a square with 72 square units of area.

where t is measured in days, and A(t) represents the amount of flooded land at time t. This function has a B-value of -0.3118.

To model the situation of the flood, we can use an exponential decay function, which represents the decreasing amount of flooded land over time. The function can be written as:

[tex]A(t) = A0 * e^{(-kt)}[/tex]

where A(t) is the amount of flooded land at time t, A0 is the initial amount of flooded land, k is a constant representing the rate of decay, and e is the mathematical constant approximately equal to 2.718.

To determine the value of k, we can use the given information that after 2 days, only 3375 acres of land were under water. Substituting t = 2 and A(t) = 3375 into the equation above, we get:

[tex]3375 = A0 * e^{(-2k)[/tex]

We also know that initially, there were 6000 acres of land under water. Substituting A0 = 6000 into the equation above, we get:

Dividing both sides by 6000, we get:

ln(0.5625) = -2k[tex]ln(0.5625) = -2k[/tex]

Taking the natural logarithm of both sides, we get:

[tex]ln(0.5625) = -2k[/tex]

Solving for k, we get:

It would be appropriate to display these data in a histogram without first plotting them in a time plot if you are looking

to analyze the distribution or frequency of herbicide usage across different amounts or categories.

A histogram can provide a clear visualization of the distribution and help identify any patterns or trends in the data.

However, if your goal is to analyze the trend of herbicide usage over time, then it would be more appropriate to use a

time plot.

A time plot will show changes in the usage of herbicides over a specific time period and help identify any seasonal

To find the probability of drawing a face card or a red card, we first need to determine the total number of favorable outcomes and then divide it by the total number of possible outcomes (52 cards in a deck).

A face card can be a King, Queen, or Jack, and there are 12 face cards in a deck (3 face cards x 4 suits). There are 26 red cards in a deck (13 cards from hearts suit and 13 cards from diamonds suit). However, we must subtract the red face cards from the total, as they are already included in the 12 face cards. There are 6 red face cards (3 face cards x 2 red suits).

So, the total number of favorable outcomes is 12 face cards + 26 red cards - 6 red face cards = 32 cards.

The chance that the number of heads will be in the range 4850 to 5150 is approximately 0.9973, or about 99.73%.

The number of heads in 10,000 coin tosses follows a binomial distribution with parameters n = 10,000 (the number of trials) and p = 0.5 (the probability of heads on a single toss).

We can approximate this binomial distribution using the normal distribution, with mean μ = np = 5000 and variance σ² = np(1-p) = 2500.

To find the probability that the number of heads is in the range 4850 to 5150, we can use the normal distribution and standardize the range using the z-score formula:

z = (x - μ) / σ

where x is the number of heads in the range we're interested in.

For the lower bound of 4850, we have:

[tex]z_lower = (4850 - 5000) / \sqrt{(2500)}[/tex]

For the upper bound of 5150, we have:

[tex]z_upper = (5150 - 5000) / \sqrt{(2500)} = 3[/tex]

Using a standard normal distribution table or calculator, we can find the probability of being within 3 standard deviations of the mean:
