Answer:  The answer is 48 degrees

Step-by-step explanation:

The probability of having a wireless mouse is 0.4 , the probability of not having a wireless keyboard is 0.3, and 0.2 is the probability of having both a wireless mouse and keyboard.

Using proper notation, we can denote the events as follows

Event A: Someone has a wireless mouse

Event B: Someone has a wireless keyboard

Then we have the following probabilities:

P(A) = 0.4 This signifies the probability that someone has a wireless mouse.

P(not B) = 0.3 This signifies the probability that someone does not have a wireless keyboard. Note that "not B" means the complement of event B, i.e., the event that someone does not have a wireless keyboard.

P(A and B) = 0.2 This signifies the probability that someone has both a wireless mouse and a wireless keyboard. The notation "A and B" means the intersection of events A and B, i.e., the event that someone has both a wireless mouse and a wireless keyboard.

Vector subtraction is done by arranging head to tail.

Vector subtraction is the process of finding the vector that results from taking away one vector from another. To perform vector subtraction, we arrange the vectors head to tail, with the tail of one vector touching the head of the other vector. We then draw a new vector from the tail of the first vector to the head of the second vector. The resulting vector is the difference between the two vectors. This can be mathematically represented as:

a - b = a + (-b)

where "a" and "b" are vectors, and (-b) is the additive inverse of b, which is the vector with the same magnitude as b but opposite in direction.

If you cut out a piece of paper in the shape of a trapezoid with only one pair of parallel sides, and the parallel sides are 2 inches apart, flipping the shape over will not change the distance between the parallel sides.

The distance between the parallel sides remains the same, which is 2 inches.

When you flip the trapezoid shape over, the orientation of the shape changes, but the dimensions and proportions remain unchanged.

The distance between the parallel sides is determined by the original shape and does not alter when you flip it over. Thus, the distance between the parallel sides of the flipped shape will still be 2 inches.

Answer:

58x + 13 + 58y

Step-by-step explanation:

First, create an expression that represents how much Zinnia made.

Since she gets $58 per week, the amount she gets can be represented by 58x.

This can also represent how much Ruby got, since she also gets $58 per week.

Then, add 13 to 58x to represent Zinnia's $13 bonus.

If we add these together, we get the expression 58x + 13 + 58x

So, 58x + 13 + 58x is the right answer.

Answer:

Answer

equation of L₁ is y = 2x - 7

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given L₂

x + 2y = 3 ( subtract x from both sides )

2y = - x + 3 ( divide through by 2 )

y = - \(\frac{1}{2}\) x + \(\frac{3}{2}\) ← in slope- intercept form

with slope m = - \(\frac{1}{2}\)

given a line with slope m then the slope of a line perpendicular to it is

\(m_{perpendicular}\) = - \(\frac{1}{m}\) = - \(\frac{1}{-\frac{1}{2} }\) = 2

slope of L₁ = 2 and passes through (3, - 1 ) , then

y = 2x + c ← is the partial equation of L₁

to find c substitute (3, - 1 ) into the partial equation

- 1 = 6 + c ⇒ c = - 1 - 6 = - 7

y = 2x - 7 ← equation of L₁

Step-by-step explanation:

Total monthly saving = $1,315

Saving is the portion of income not spent on current expenditures. In other words, it is the money set aside for future use and not spent immediately.

Given:

                        Oakland     Los Angeles  

Cost Housing       $565        $1200

Food                     $545        $655

Health Care         $245        $495

Taxes                    $450         $625

Other Necessities $350        $495

Now,

Saving in house

= $1200 - $565

= $635

Saving in food

= $655 - $545

= $110

Saving in health care

= $495 - $245

= $250

Saving in taxes

= $625 - $450

= $175

Saving in necessities

= $495 - $350

= $145

Total saving = $635+$110+$250+$175+$145

                    = $1,315

Hence, the monthly savings should be $1,315.

the solution to the initial value problem is:

y = (1/2)\(e^{(6t - 24)\) + (5 - (1/2)e⁻¹²)\(e^{(4t - 12)\)

To solve the initial value problem, we'll use the method of integrating factors. The differential equation is in the form

dy/dt - 2y = \(e^{(4(t - 3))\)

First, we identify the integrating factor, which is given by the exponential of the integral of the coefficient of y, in this case, -2t:

μ(t) = \(e^-2t\)

Now, we multiply the entire equation by the integrating factor:

\(e^{(-2t)\) * (dy/dt - 2y) = \(e^{(-2t)\) * \(e^{(4(t - 3))\)

Simplifying the right side:

\(e^{(-2t)\)  * (dy/dt - 2y) = \(e^{(-2t)\)  * \(e^{(4t - 12)\)

\(e^{(-2t)\)  * (dy/dt - 2y) = \(e^{(-2t + 4t - 12)\)

\(e^{(-2t)\)  * (dy/dt - 2y) = \(e^{(2t - 12)\)

Now, we can rewrite the left side using the product rule:

d/dt (\(e^{(-2t)\) * y) = \(e^{(2t - 12)\)

Integrating both sides with respect to t:

∫d/dt (\(e^{(-2t)\)  * y) dt = ∫ \(e^{(2t - 12)\) dt

Integrating the left side gives:

\(e^{(-2t)\) * y = ∫ \(e^{(2t - 12)\) dt

Integrating the right side:

\(e^{(-2t)\) * y = (1/2) \(e^{(2t - 12)\)+ C

where C is the constant of integration.

Next, we can solve for y:

y = \(e^{(2t - 12 + 2t)\) * [(1/2) \(e^{(2t - 12)\)+ C]

Simplifying further:

y = \(e^{(4t - 12)\) * [(1/2) \(e^{(2t - 12)\) + C]

y = (1/2)\(e^{(6t - 24) + Ce^{(4t - 12)\)

To find the value of C, we use the initial condition y(0) = 5:

5 = (1/2)\(e^{(0 - 24)} + Ce^{(0 - 12)\)

5 = (1/2)\(e^{(-24)} + Ce^{(-12)\)

Solving for C:

C = 5 - (1/2)e⁻²⁴ * e¹²

C = 5 - (1/2)e⁻¹²

Finally, substituting the value of C back into the equation for y:

y = (1/2)\(e^{(6t - 24)\) + (5 - (1/2)e⁻¹²)\(e^{(4t - 12)\)

Therefore, the solution to the initial value problem is:

y = (1/2)\(e^{(6t - 24)\) + (5 - (1/2)e⁻¹²)\(e^{(4t - 12)\)

Answer: Where they bisect each other at W the 2 lines  are split in the center by one another which means both of those lines are 180

Step-by-step explanation:

Answer:

  SAS

Step-by-step explanation:

You have segments UT and VS bisecting each other at point W, and you want to show triangles UWV and TWS ae congruent.

Each half of the segment is congruent to the other half:

  UW≅TW and VW≅SW

The angles between them are vertical angles so are congruent:

  ∠UWV ≅ ∠TWS

So, you have congruent corresponding sides and the angle between. The triangles UWV and TWS are congruent by the SAS congruence postulate.

Additional comment

You can use substantially the same argument to say triangles UWS and TWV are congruent. The proof above shows UV≅TS. The congruence of triangles UWS and TWV shows US≅TV. Hence the figure TSUV is a parallelogram.

If you were not restricted to using just rectangles to fill up the space between the curve and the x-axis, a different geometric shape that might give a more accurate estimate for this area is a trapezoid.

Using trapezoids would likely yield a more accurate result because they can better approximate the curve's shape.
Here's a step-by-step explanation of how using trapezoids can provide a more accurate estimate:

Divide the interval on the x-axis into equal subintervals.

In each subinterval, form a trapezoid by connecting the endpoints of the subinterval to the curve and then closing the shape by drawing a horizontal line from the curve to the x-axis

Calculate the area of each trapezoid using the formula: A = (1/2) * (base1 + base2) * height, where base1 and base2 are the lengths of the parallel sides of the trapezoid (the lengths along the x-axis and the curve), and the height is the length of the vertical line connecting the two bases (the width of the subinterval)

Sum the areas of all trapezoids to approximate the total area between the curve and the x-axis.

The reason trapezoids can provide a more accurate estimate is that they can closely follow the shape of the curve, especially when the curve is not a straight line. Since trapezoids have two different base lengths, they can better accommodate the changes in the curve's slope within each subinterval. This results in a closer fit to the curve compared to using rectangles, which can overestimate or underestimate the area depending on the curve's concavity.

Overall, using trapezoids for estimating the area under a curve can provide more accurate results, especially as the number of subintervals increases.

Step-by-step explanation:

let the third side of the triangle be x

using Pythagoras' identity in the right triangle.

x² + 7² = 16²

x² + 49 = 256 ( subtract 49 from both sides )

x² = 207 ( take square root of both sides )

x = \(\sqrt{207}\) ≈ 14.4 m ( to 1 decimal place )

the perimeter (P) is then the sum of the 3 sides

P = 7 + 16 + 14.4 = 37.4 m

The probability associated with obtaining a particular value of z is referred to as its statistical probability or simply its probability. It represents the likelihood of observing a specific value of z in a given statistical distribution.

The probability of a specific value of z can be calculated using various statistical methods, depending on the distribution being considered. In statistics, z represents a standard score or a z-score. It is a measure of how many standard deviations a particular value is away from the mean of a distribution. The probability associated with a specific value of z is determined by the characteristics of the distribution, such as its shape, mean, and standard deviation. Different distributions, such as the normal distribution or the t-distribution, have different methods for calculating probabilities associated with specific values of z.

The probability associated with a particular value of z can be useful in hypothesis testing, confidence interval estimation, or determining the likelihood of an event occurring. By understanding the probability distribution of z-values, statisticians can make informed decisions and draw conclusions based on data analysis.

Rounded to one decimal place, the new forecasted trend for the current period is 31.3.

To calculate the new forecasted trend for the current period using exponential smoothing, we need the current observed value (33), the previous forecasted value (31), and the smoothing constant (β) of 0.15.

Exponential smoothing assigns a weight to the previous forecast and combines it with the current observed value to generate a new forecast. The formula for exponential smoothing is:

New Forecast = (1 - β) * Previous Forecast + β * Current Observed Value

Substituting the given values, we can calculate the new forecasted trend:

New Forecast = (1 - 0.15) * 31 + 0.15 * 33

           = 0.85 * 31 + 0.15 * 33

           = 26.35 + 4.95

           = 31.3

Exponential smoothing is a forecasting technique that assigns more weight to recent observations while considering past forecasts. The smoothing constant, β, determines the rate at which the influence of past forecasts diminishes as new observations become available. In this case, with a β value of 0.15, the new forecast is closer to the current observed value compared to the previous forecast, reflecting a higher sensitivity to recent data.

It's important to note that exponential smoothing assumes a relatively stable trend and does not account for other factors or seasonality that may impact the forecast. It is a simple method that can be useful for generating short-term forecasts based on recent trends, but it may not be suitable for all forecasting scenarios.

Answer: The height of the cylindrical garbage can can be calculated using the formula for the volume of a cylinder:

V = πr^2h

where V is the volume of the cylinder, r is the radius (which is half of the diameter), and h is the height of the cylinder.

First, we need to convert the diameter from feet to inches, since the volume is given in cubic inches. One foot is equal to 12 inches, so 2 feet is equal to 24 inches.

The radius of the cylinder is half of the diameter, so:

r = 24/2 = 12 inches

Now we can plug in the values we have into the formula and solve for h:

50nft = π(12 inches)^2h

We can simplify this by first converting the volume from cubic feet to cubic inches. Since 1 foot is equal to 12 inches, 1 cubic foot is equal to (12 inches)^3 = 1728 cubic inches. Therefore:

50nft = 50 x 1728 cubic inches = 86400 cubic inches

Substituting this value into the formula, we get:

86400 = π(12 inches)^2h

Simplifying further:

86400 = 144πh

Dividing both sides by 144π, we get:

h = 86400 / (144π) inches

Using a calculator to evaluate this expression, we get:

h ≈ 199.08 inches

Therefore, the height of the cylindrical garbage can is approximately 199.08 inches.
