Answers

Answer 1

The correlation coefficient may assume any value between -1 and 1. Correct answer option A.

This means that the coefficient might be negative, zero, or positive, with -1 being a perfect negative correlation, 0 representing no connection, and 1 representing a perfect positive correlation.

The correlation coefficient is a numerical measure of two variables' linear connection. It is a measure of the strength of the link between two variables. A correlation coefficient of 1 indicates that there is a perfect positive connection, a coefficient of -1 indicates that there is a perfect negative correlation, and a coefficient of 0 shows that there is no correlation between the two variables.

a 20-volt electromotive force is applied to an lr-series circuit in which the inductance is 0.1 henry and the resistance is 40 ohms. find the current i(t) if i(0) = 0.
i(t) = ___
Determine the current as t → [infinity].
lim t→[infinity] i(t) =_____

Answers

The time becomes infinity, i(t) will become constant, i.e., lim t→[infinity] i(t) = 0.

The current of the given LR-series circuit can be determined using the formula I = (E/R) * (1 - e^-Rt/L).The current i(t) if i(0) = 0 in the LR-series circuit is given by i(t) = 0.125A. The current as t → [infinity] is given by lim t→[infinity] i(t) = 0.How to solve this?The formula for the current in the LR-series circuit is given by:Where E is the electromotive force, R is the resistance, L is the inductance, t is time and I is the current.I = (E/R) * (1 - e^-Rt/L)Given E = 20V, R = 40Ω, L = 0.1H, and i(0) = 0Substitute these values in the above formula.I = (20/40) * (1 - e^-40t/0.1)I = 0.5(1 - e^-400t)I = 0.5 - 0.5e^-400tSo the current is i(t) = 0.5 - 0.5e^-400t.Limit of t as t → [infinity] means that when the time is allowed to run infinitely, then the current will become constant. Hence, when the time becomes infinity, i(t) will become constant, i.e., lim t→[infinity] i(t) = 0. Answer: The current is i(t) = 0.5 - 0.5e^-400t. Limit of t as t → [infinity] means that when the time is allowed to run infinitely, then the current will become constant. Hence, when the time becomes infinity, i(t) will become constant, i.e., lim t→[infinity] i(t) = 0.

An urn contains eight green balls and six red balls. Four balls are randomly selected from the urn in succession, with replacement. That is, after each draw the selected ball is returned. What is the probability that all four balls drawn are red. Round your answer to three decimal places

Answers

The probability of drawing four red balls in succession, with replacement, is 0.04 or 4%.

Since we are replacing the ball after each draw, the probability of drawing a red ball remains the same for each draw. The probability of drawing a red ball on any given draw is:

P(Red) = Number of Red Balls / Total Number of Balls

P(Red) = 6 / (8 + 6)

P(Red) = 0.4286

So, the probability of drawing four red balls in a row is the product of the probability of drawing a red ball four times in a row:

P(4 Red Balls) = P(Red) * P(Red) * P(Red) * P(Red)

P(4 Red Balls) = 0.4286 * 0.4286 * 0.4286 * 0.4286

P(4 Red Balls) = 0.04 or 4%

LOVE is a kite. LV and OE are diagonals. The segments DV = 9cm and LE = 15cm, and

Answers

The lengths of LV and OE are 15cm, and the lengths of LD and EV are 3√7 cm and 9/√7 cm, respectively.

Since LOVE is a kite, LV and OE are perpendicular bisectors of each other. Let the length of LD be x, and the length of EV be y. Then, we can use the Pythagorean theorem and the fact that the diagonals bisect each other to set up two equations:

x² + (LV/2)² = DV²/4

y² + (OE/2)² = LE²/4

Simplifying each equation and substituting the given values, we get:

x² + (LV/2)² = 81/4

y² + (OE/2)² = 225/4

We also know that the diagonals bisect each other, so we can set up another equation:

LV/2 + OE/2 = LO = VE

Substituting the given value for LE, we get:

LV/2 + OE/2 = 15

Solving this equation for one of the variables, we get:

LV = 30 - OE

Substituting this expression into the first equation above, we get:

x² + ((30 - OE)/2)² = 81/4

Simplifying and rearranging, we get:

OE² - 60OE + 675 = 0

Using the quadratic formula, we get:

OE = (60 ± √(3600 - 2700)) / 2

OE = 15 or 45

If OE = 15, then LV = 30 - 15 = 15, and we can solve for x and y:

x² + 7.5² = 81/4

y² + 7.5² = 225/4

Solving these equations, we get:

x = 3√7

y = 9/√7

If OE = 45, then LV = 30 - 45 = -15, which is impossible for a length. Therefore, the solution is:

LV = OE = 15

x = 3√7

y = 9/√7

Answer:

the area of triangle OAP is 12 square units.

Step-by-step explanation:

First, we need to find the coordinates of the center of the circle, which is (0, 0), and the radius, which is √40 = 2√10.

Since line I is a tangent to the circle at point A, it is perpendicular to the radius OA at point A. Therefore, OA is perpendicular to line I and forms a right angle with it.

We can find the equation of line I using the point-slope form:

slope of radius OA = (0 - 6) / (0 - 2) = -3

slope of line I = 1 / 3 (because it is perpendicular to OA)

equation of line I: y - 6 = (1/3)(x - 2)

simplifying, we get: y = (1/3)x + 4

To find the x-coordinate of point P, we need to solve for x when y = 0:

0 = (1/3)x + 4

x = -12

Therefore, point P has coordinates (-12, 0).

Now, we can find the coordinates of point O, which is the origin (0, 0), and the coordinates of point A, which are given as (2, 6).

To find the area of triangle OAP, we can use the formula for the area of a triangle:

Area = (1/2) x base x height

We know that OA is the base of the triangle and its length is the radius of the circle, which is 2√10.

To find the height of the triangle, we need to find the distance from point A to line I, which is the perpendicular distance. We can use the formula for the distance between a point and a line:

distance = |ax + by + c| / √(a² + b²)

where a, b, and c are the coefficients of the equation of the line, and x and y are the coordinates of the point.

In this case, the equation of line I is y = (1/3)x + 4, so a = -1, b = 3, and c = -12.

Substituting the values, we get:

distance = |(-1)(2) + (3)(6) - 12| / √((-1)² + 3²)

distance = |6| / √10

distance = 3√10 / 5

Now we can substitute the values into the formula for the area of the triangle:

Area = (1/2) x base x height

Area = (1/2) x 2√10 x (3√10 / 5)

Area = 6/5 x 10

Area = 12

Therefore, the area of triangle OAP is 12 square units.

Answers

The statement "Ten cards are selected out of a 52 card deck without replacement and the number of Jacks is observed. This is an example of a Binomial Experiment" is false.

What is a Binomial Experiment?

A binomial experiment is an experiment that is repeated multiple times with each repetition having only two potential outcomes. In a binomial experiment, the probability of success remains constant from trial to trial.

The criteria for a binomial experiment are as follows:

The experiment is made up of a fixed number of trials.There are only two possible results for each trial: success and failure.The probability of success for each trial is the same.The trials are all independent of one another.The formula for calculating the probability of x successes in n trials is:

P(x) = (ⁿCₓ)(pˣ)(q^(n-x))

Where p is the probability of success, q is the probability of failure (q = 1 - p), and ⁿCₓ is the combination formula.

Therefore, the statement "Ten cards are selected out of a 52-card deck without replacement and the number of Jacks is observed. This is an example of a "Binomial Experiment" being false. This is because the probability of drawing a jack changes with each trial, as the deck's composition changes after each card is drawn.

Probability is a branch of mathematics that deals with the study of the likelihood or chance of an event occurring. It is a way of quantifying uncertainty and making predictions about the outcome of a random process. The probability of an event is represented by a number between 0 and 1, where 0 represents an impossible event, and 1 represents a certain event.

Probability theory provides a set of rules and tools for analyzing and modeling the behavior of random phenomena, such as coin flips, dice rolls, or the occurrence of a disease in a population. These tools include probability distributions, which describe the likelihood of different outcomes, and statistical inference, which allows us to make predictions based on a sample of data.​

Answers

(a) Using the Trapezoidal rule, T8 = (1/16)[cos(0) + 2cos(1/16) + 2cos(2/16) + ... + 2cos(7/16) + cos(1)].

Using the Midpoint rule, M8 = (1/8)[cos(1/16) + cos(3/16) + ... + cos(15/16)].

(b) The error in the Trapezoidal rule is bounded by (1/2880)(1-0)^3(max|f''(x)|), where f''(x) = -4x^2sin(x^2) and 0 <= x <= 1. Therefore, the error in T8 is approximately 0.00014. The error in the Midpoint rule is bounded by (1/1920)(1-0)^3(max|f''(x)|), which gives an approximate error of 0.00011 for M8.

(c) Let n be the number of intervals in the approximation.

Then, the error bound for the Trapezoidal rule is (1/2880)(1-0)^3(max|f''(x)|)(1/n^2), and the error bound for the Midpoint rule is (1/1920)(1-0)^3(max|f''(x)|)(1/n^2).

Setting these equal to 0.0001 and solving for n, we get n >= 129 and n >= 160 for the Trapezoidal and Midpoint rules, respectively. Therefore, we should choose n >= 160 to ensure that both approximations are accurate to within 0.0001.

A function is shown.

f(x) = x² + 2x - 3

Use the Add Point tool to show the x-intercepts and maximum or minimum of the function.

Answers

the x-intercepts are (-3, 0) and (1, 0), and the minimum occurs at the vertex (-1, -4).

What is a function?

In mathematics, a function is a relationship between a set of inputs (called the domain) and a set of possible outputs (called the range), where each input is associated with exactly one output.

To find the x-intercepts, we set the function equal to zero and solve for x:

x² + 2x - 3 = 0

Using the quadratic formula, we get:

x = (-b ± sqrt(b² - 4ac)) / 2a

Where a = 1, b = 2, and c = -3.

Plugging in the values, we get:

x = (-2 ± sqrt(2² - 4(1)(-3))) / 2(1)

Simplifying, we get:

x = (-2 ± sqrt(16)) / 2

x = (-2 ± 4) / 2

x1 = -3, x2 = 1

Therefore, the x-intercepts are (-3, 0) and (1, 0).

To find the maximum or minimum, we can use the vertex form of the equation:

f(x) = a(x - h)² + k

where (h, k) is the vertex.

To get the vertex, we complete the square:

f(x) = x² + 2x - 3

f(x) = (x + 1)² - 4

The vertex is (-1, -4), which is a minimum since the coefficient of the squared term is positive.

Therefore, the x-intercepts are (-3, 0) and (1, 0), and the minimum occurs at the vertex (-1, -4).

Answers

The correct option for question 1 is (c), while the correct option for question 2 is (a).

When answering questions on the platform Brainly, it is important to always be factually accurate, professional, and friendly. In addition, one should be concise and not provide extraneous amounts of detail, ignore any typos or irrelevant parts of the question, repeat the question in their answer, and provide a step-by-step explanation.Using Holtz model, the factor of growth in a time series is accounted for by adding trend exponential smoothing to estimate. This is because Holtz model is a double exponential smoothing method that can account for both level and trend in the time series. The exponential smoothing factor α, which ranges between 0 and 1, is used to control the smoothness of the trend parameter.In addition, the adaptive response rate single exponential smoothing model is termed adaptive because it has the ability to respond to changes in the pattern of data. This is because the smoothing parameter changes each period, allowing the model to adjust to the changing patterns in the time series. Therefore, the correct option for question 1 is (c), while the correct option for question 2 is (a).

Erica's bedroom is shaped like the letter L. One of the rectangles that makes up her room measures 10 feet by 8 feet. The other rectangle measures 12 feet by 8 feet. What is the area of her entire bedroom?​

Answers

the area of her entire bedroom is 176 feet².

What is rectangle?

A rectangle is a parallelogram with four right angles in the Euclidean plane. It can also be described as a parallelogram with a right angle or an equiangular quadrilateral, where equiangular denotes that all of its angles are equivalent. A square is a rectangle with four equal edges.

What is area?

The size of a section on a surface is determined by its area. Surface area refers to the area of an open surface or the border of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a shape or planar lamina.

Area of first rectangle = length * breadth= 10*8=80 feet²

Area of second rectangle = length * breadth= 12*8 = 96 feet²

Total area of bedroom= 80+96= 176 feet²

suppose you start at the origin, move along the x-axis a distance of 7 units in the positive direction, and then move downward a distance of 6 units. what are the coordinates of your position? (x, y, z)

Answers

The coordinates of your position If we start at the origin, we are moving only along the x-axis  of  a distance of 7 units in positive direction and then only in the negative y-axis direction and  z-coordinate is zero are (7,-6,0).

The origin is the point in space that has a position of (0, 0, 0), which represents the point where the x, y, and z axes intersect.

The first step is to move 7 units in the positive x direction. The positive x direction is the direction in which x values increase. Therefore, we move to the right along the x-axis to the point (7, 0). This means that we have moved 7 units along the x-axis, and our position is now (7, 0, 0).

The second step is to move downward a distance of 6 units. Since we are not moving in the x direction, we are only changing our position along the y-axis. Moving downward in the y direction means decreasing our y-coordinate. Therefore, we move 6 units downward from our current position to the point (7, -6, 0).

Therefore, the coordinates of our position are (7, -6, 0)
