what is the name for a type of experiment in which random samples of varying size are repeatedly drawn from a large population?

Answers

Monte Carlo  is the name for a type of experiment in which random samples of varying size are repeatedly drawn from a large population.

Define monte Carlo experiment.

A large class of computational techniques known as "Monte Carlo procedures" or "Monte Carlo experiments" rely on repeated random sampling to get numerical results. The core idea is to leverage randomness to find solutions to issues that, in theory, may be deterministic. They are frequently applied to mathematical and physical issues and are particularly helpful when it is challenging or impossible to apply alternative strategies. The three problem types of optimization, numerical integration, and producing draws from a probability distribution[1] are where Monte Carlo methods are most frequently applied.

Given,

Monte Carlo  is the name for a type of experiment in which random samples of varying size are repeatedly drawn from a large population.

In theory, every problem with a probabilistic interpretation can be solved using Monte Carlo methods. By applying the empirical mean (also known as the "sample mean") of independent samples of the variable, one can approximate integrals described by the expected value of a random variable according to the law of large numbers.

1)  The value of x is 31°

The correct answer is an option (b)

2) The value of arc a is 68°

The correct answer is an option (c)

3) The value of angle b is 28°

The correct answer is an option (a)

4) The value of angle s is 35°

The correct answer is an option (a)

5) The measure of angle y cannot be determined.

The correct answer is an option (d)

6) The value of arc Z is 126°

The correct answer is an option (c)

We know that  any two inscribed angles in a circle with the same intercepted arcs are congruent.

Also, the Inscribed Angle Theorem states that the measure of an inscribed angle is equal to the half the measure of its intercepted arc.

1) In the first question, the inscribed angles x and angle that measures 31° have the same intercepted arc.

So, the measure of angle x is 31°

The correct answer is an option (b)

2) We need to find the measure of arc 'a'

Using Inscribed Angle Theorem, the measure of arc a would be twice the measure of angle 34°

So, the measure of arc 'a' would be a = 2 × 34

                                                         a = 68°

The correct answer is an option (c)

3) We need to find the measure of angle b.

Using Inscribed Angle Theorem, the measure of angle b would be half the arc that measures 56°

so, the measue os angle b = (1/2) × (56°)

                                          =  28°

The correct answer is an option (a)

4) The arc subtended by angle s would be equal to 180° - 110° = 70°

By Inscribed Angle Theorem, the measure of angle s would be half the measure of aubtended arc

i.e., s = (1/2) ×   70°

     s = 35°

The correct answer is an option (a)

5) We need to find the measure of angle y.

We know that the alternate segment theorem states that the angle formed between the tangent and the chord through the point of contact of the tangent in any circle is equal to the angle formed by the chord in the alternate segment.

So, the measure of angle y cannot be determined.

The correct answer is an option (d)

6) Using Inscribed Angle Theorem, the measure of arc a would be twice the measure of angle 85°

2 × 85 = m + 90

170 = m + 90

m = 80°

The measure of angle subtended by arc (90° + 64°) would be,

1/2 (90° + 64°) = 77°

The angle subtended by arc (z° + 64°) would be, 1/2(z° + 64°)

And the angle subtended by arc (z° + 80°) would be, 1/2(z° + 80°)

We know that the sum of all angles of quadrilateral is 360°

⇒ 85° + 77° + 1/2(z° + 80°) + 1/2(z° + 64°) = 360°

⇒ 1/2(z° + 80° + z° + 64°) = 360° - (85 + 77)

⇒ z° + 80° + z° + 64° = 2 × 198

⇒ 2z° + 80° + 64° = 396°

⇒ 2z° + 144° = 396°

⇒ 2z° = 252°

⇒ z = 126°

Which statement about geometric figures is true?

O On a coordinate plane, parallel lines have the same slope.
O Two lines on a coordinate plane that do not intersect are perpendicular.
O An angle is formed by a set of points that are all equidistant from a common point.

Answers

Answer:

B

Step-by-step explanation:

On a coordinate plane, parallel lines have the same slope as geometric figures are true. Thus option B is correct.

What are geometric figures?

Marks, splines, spheres, and curved are used to build enclosed geometric shapes. We can see these shapes all around us. Illustrations of geometric shapes include circles, rectangles, triangles, and others. Any configuration of points, columns, or angles is a geometry figure.

A point is the most fundamental algebraic concept because it has no boundaries. Simply put, a point upon that plane is a location. A dot is used to symbolize it. A plane can be identified by three non-straight-line points.

As two or much more vectors seldom cross each other and are located on the same dimension, these are said to be parallel. The slope of these lines is constant. Coplanar lines that seem to be parallel are the ones that don't cross. Therefore, option B is the correct option.

The Area is a two-dimensional scalar quantity. The area of the composite figure is 264 cm².

What is the area?

The area of a two-dimensional region, form, or planar lamina in the plane is the quantity that represents its extent. On the two-dimensional surface of a three-dimensional object, the surface area is its counterpart.

The composite figure can be broken down into four parts a square(A), a triangle(B) and two rectangles(C and D).

Now, if the area of the composite figure is taken out it will be,

\(\text{Area of composite}=\text{Area of Square A} + \text{Area of triangle B} + \text{Area of Rectangle C} + \text{Area of Rectangle D}\\\)

a pair of fair dice are rolled and the total is recorded. if this is done ten times, what is the probability that 7 is recorded at least three times?

Answers

The probability that 7 is recorded at least three times is 7/12 times.

7 is recorded at least three times in one time (A) = (2, 5), (2, 6), (3, 4) (3, 5) (3, 6), (4, 3) ,(4, 4) ,(4, 5) ,(4, 6), (5, 2) ,(5, 3), (5, 4), (5, 5) (5, 6), (6, 1) (6, 2) (6, 3) (6, 4) (6, 5), (6, 6).

n(A) = 21

7 is recorded at least three times in ten times (B) = 10*n(A)

n(B) = 10*21

      = 210

Total possible outcomes at one time = 36

Total possible outcomes at ten times, [n(S)] = 360

The probability that 7 is recorded at least three times = 7 is recorded at least three times in ten times / Total possible outcomes at ten times

P(B) = n(B) / n(S)

       = 210/360

       = 7/12

Hence,  the probability that 7 is recorded at least three times is 7/12 times.

Answers

Answer is
Part 1) y = 3x -5
Part 2) y = 2x + 7

Step by step

Part 1 - they gave you slope of 3 and y intercept of -5

Your equation set up is y= mx + b

M is slope and b is y intercept so

y = 3x - 5

Part 2 - they give you (-1, 5) and slope (m) 2

Your formula is y - y1 = m (x - x1)

y - 5 = 2 (x - -1)

Answers

To find Keegan's optimal consumption bundle of pita wraps and bubble tea, we need to determine the combination that maximizes his utility while staying within his budget of $30. The price of a pita wrap is $6, and the price of a bubble tea is $3.

Step 1: Calculate the maximum quantity of each item Keegan can buy with his budget.
- Pita wraps: $30 / $6 = 5 wraps
- Bubble teas: $30 / $3 = 10 bubble teas

Step 2: List all possible combinations of pita wraps and bubble teas within the budget.
1. 0 wraps and 10 bubble teas
2. 1 wrap and 8 bubble teas
3. 2 wraps and 6 bubble teas
4. 3 wraps and 4 bubble teas
5. 4 wraps and 2 bubble teas
6. 5 wraps and 0 bubble teas

Step 3: Determine the optimal consumption bundle.
Without information about Keegan's preferences, we cannot definitively determine his optimal consumption bundle. However, these six combinations represent all possible bundles that Keegan can purchase with his $30 budget. Keegan's optimal consumption bundle would depend on his personal preferences for pita wraps and bubble teas.

The probability of observing less than 3 heads is  0.6875 when you flip a coin four times.

Probability is a method that is used to find the number of events likely to occur. There are 3 types of probability which are Theoretical Probability, Experimental Probability, and Axiomatic Probability.

The formula used to find the probability is given as ;

P(E) = Number of Outcomes / Total Number of Outcomes.

We have to find the probability of observing less than 3 heads.

if the coin is tossed four times then the total number of outcomes is 16

Let X be the number of heads observed in 4 tosses of a coin, Then

the probability of getting x heads in 4 flips  is P ( X = x )

The probability of observing less than 3 heads is expressed as,

P ( X < 3 ).

P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)

= 1/16 + 4/16 + 6/16

= 11/16

the answer is 22.5 or 22 whole number 1/2.

15 divided by 4 and 1/6 is equal to 18/5 or 3 and 3/5.

To divide 15 by 4 and 1/6, we can convert the mixed number 4 and 1/6 into an improper fraction.

4 and 1/6 can be written as (4 x 6 + 1) / 6 = 25/6.

Now, we can divide 15 by 25/6:

15 ÷ (25/6) = 15 x (6/25)

= (15 x 6) / 25

= 90/25.

Now, the fraction 90/25 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 5:

= 90/25

= (90 ÷ 5) / (25 ÷ 5)

= 18/5.

The transformation of a function occurs in a fancy way such that a function maps itself. f: x → x.

From the given information:

Let's take a look at the function f(x) that goes through 0 just when x = 0. Now we want to move it to the right by 2. It implies that it has to go through 0 when x = +2.

Now, we have to add 2 to x, then the function becomes f'(x) = f(x-2) will be shifted by 2 units to the right.

Similarly, the same scenario occurs when shifting up. Again imagine your function passes 0 when x = 0.  We have to add 3. Now, the function f’’(x) = f(x) + 3 will be shifted by 3 units up.

Combining the two transformations, we have:

g(x) = f(x-2) + 3

Therefore, we can conclude that the function implies that the graph g(x) is shifted two units right and three units up.

Answers

\(\text{The answer = P = 15000( 1 - 0.15)}^t\)

The population is decreasing by 15% every year

The initial population = 15,000

Since it decreases every year

\(\begin{gathered} P=a(1+r)^t \\ \text{Where a = initial amount},\text{ r = rate, t = time} \end{gathered}\)

Decreases every year = (100 - 15)

The rate of the population every year = 75%

\(P=15,000(1-0.15)^t\)

What this simply means is that the population of California keep decreasing by 15%

Assuming the population of California in 2018 is 15000

By 2019 , it would have decreased by 15%

The new population in 2019 will now be = (100 - 15)% x 15000
