Step-by-step explanation:

The probability that she chooses an outfit consisting of the flat heel or spike heel shoes, the twill or the denim pants, and the white or black shirt is given by P ( A ) = 22.22 %

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

Probability = number of desirable outcomes / total number of possible outcomes

The value of probability lies between 0 and 1

Given data ,

Jackie has a choice of 3 pairs of shoes, 3 pants, and 4 shirts that can make an outfit for today.

Each pair of shoes has a different heel height, each pair of pants is made from a different fabric, and each shirt is a different color.

So , There are a total of 3 x 3 x 4 = 36 possible outfits.

The number of outfits with the specified choices is:

2 (choices of shoes) x 2 (choices of pants) x 2 (choices of shirts) = 8

Therefore, the probability that Jackie chooses an outfit consisting of the specified choices is:

8 / 36 = 2 / 9 ≈ 0.2222 or about 22.22%

Hence , the probability is P ( A ) = 22.22 %

Answer:

Step-by-step explanation:

An exponential decay function that models the situation is Aₙ = (900)(1-0.18)ˣ.

An exponential function's curve is created by a pattern of data called exponential decay, which exhibits higher decreases over time.

The exponential decay function:

Aₙ = A₀(1-r)ˣ, where y = Final amount, A₀ = Initial amount, r = Rate of decay in decimal form, x = Time.

Given:

Joe bought a computer for $900.

The value of the computer depreciates at a rate of 18% each year.

An exponential decay function that models the situation is,

Aₙ = A₀(1-r)ˣ, where y = Final amount, A₀ = Initial amount, r = Rate of decay in decimal form, x = Time.

So,

Aₙ = (900)(1-0.18)ˣ

Step-by-step explanation:

The Fourier series coefficients can be calculated using the formula:

Ck = (1/T) * ∫[x(t) * exp(-jkω0t)] dt

To sketch the signal x(t), let's analyze it step by step.

i. Sketching the signal x(t):

The given input signal x(t) is defined as:

x(t) = 8(t - 1 - 3k) - 8(t - 2 - 3k), where k = -∞ to 0.

Let's consider different cases based on the values of t:

Case 1: When t < 1 - 3k:

In this case, both terms inside the brackets become negative, resulting in x(t) = 8(0) - 8(0) = 0.

Case 2: When 1 - 3k < t < 2 - 3k:

In this case, the first term inside the brackets becomes positive and the second term inside the brackets becomes negative. Therefore, x(t) = 8(t - 1 - 3k) + 8(0) = 8(t - 1 - 3k).

Case 3: When t > 2 - 3k:

In this case, both terms inside the brackets become positive, resulting in x(t) = 8(t - 1 - 3k) - 8(t - 2 - 3k) = 0

ii. Finding the Exponential Fourier series of x(t):

To find the Exponential Fourier series coefficients, we need to calculate the complex exponential Fourier series representation of the signal x(t).

The complex exponential Fourier series representation of a periodic signal x(t) with period T can be expressed as:

x(t) = ∑[Ck * exp(jkω0t)]

where Ck represents the Fourier series coefficients, j is the imaginary unit, k is an integer, and ω0 = 2π/T.

In this case, the signal x(t) is not periodic, but we can still find the Fourier series coefficients for a single period.

Given the input signal x(t), we can see that it consists of two rectangular pulses:

The first pulse starts at t = 1 - 3k and ends at t = 2 - 3k.

The second pulse starts at t = 2 - 3k and ends at t = 3 - 3k.

Therefore, for a single period, we can express x(t) as a sum of these two pulses:

x(t) = 8(t - 1 - 3k) - 8(t - 2 - 3k) = 8(t - 1 - 3k) for 1 - 3k < t < 2 - 3k

Now, we need to find the Fourier series coefficients Ck for this pulse.

The Fourier series coefficients can be calculated using the formula:

Ck = (1/T) * ∫[x(t) * exp(-jkω0t)] dt

Since we have a single period between t = 1 - 3k and t = 2 - 3k, we can take the period T = 1.

Now, let's calculate the Fourier series coefficients for the given signal:

Ck = (1/1) * ∫[8(t - 1 - 3k) * exp(-jk2πt)] dt

Ck = 8 * ∫[(t - 1 - 3k) * exp(-jk2πt)] dt

Step-by-step explanation:

I hope that is useful for you :)

Answer:

y=0x - 4

Step-by-step explanation:

perpendicular to the y-axis means parallel to the x-axis.

that would be a horizontal line and they have no slope. so m=0

(0, -4) is the y-intercept since the y intercept is when x is zero.

b=-4

y=mx+b

y=0x - 4

Answer:

y = - 9x + 14

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 )

calculate m using the slope formula

m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)

with (x₁, y₁ ) = (- 4, 50 ) and (x₂, y₂ ) = (5, - 31 )

m = \(\frac{-31-50}{5-(-4)}\) = \(\frac{-81}{5+4}\) = \(\frac{-81}{9}\) = - 9 , then

y = - 9x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (5, - 31 )

- 31 = - 9(5) + c = - 45 + c ( add 45 to both sides )

14 = c

y = - 9x + 14 ← equation of line

Considering the slope of the lines, it is found that the lines going through the points are neither parallel nor perpendicular.

The slope, given by change in y divided by change in x, determines if the lines are parallel, perpendicular, or neither, as follows:

In this problem, the slopes are given as follows:

(2+sqrt3)

Step-by-step explanation:

Assertion(A): (2-√3) is one zero of the quadratic polynomial then the other zero will be (2+√3).

Reason (R): Irrational zeros (roots) always occurs in pairs.

Since the given polynomial is a quadratic so it has only two zeros. Let other zero be x. Hence, the other zero is (2 -√3).

Polynomials that have only one zero mean both values of the variable are the same. This is the case of equal zeros of a quadratic equation. Let x be the variable of a quadratic equation and both zeroes of the quadratic equation are 2, i.e., equal roots.

what ever is bigger So if 12 and 20 which is bigger 20

Answer:

x=10°

5x=50°

2x=20°

Step-by-step explanation:

The sum of angles in a triangle is 180°, so 5x°+2x°+110° must be equal to 180. So solving this equation we get 5x+2x+110=180, 7x+110=180, 7x=70, and x=10, so our answer is x=10.

Now to find 5x, we multiply by 5, and get 5x=50

To find 2x, we multiply x by 2, and get 2x=20.

We are 90% confident that the true difference in proportions between France and the United States falls between -0.1783 and 0.1383.

What is proportion?

The size, number, or amount of one thing or group as compared to the size, number, or amount of another. The proportion of boys to girls in our class is three to one.

The point estimate for the difference in proportions between France and the United States is:

p₁ - p₂ = (60/120) - (26/50) = 0.5 - 0.52 = -0.02

We can use the following formula to calculate the standard error of the difference in proportions:

SE = √(p₁ * (1 - p₁) / n₁ + p₂ * (1 - p₂) / n₂)

where n₁ and n₂ are the sample sizes.

SE = √((0.5 * 0.5 / 120) + (0.52 * 0.48 / 50))

SE = 0.0936

To construct a 90% confidence interval, we can use the formula:

(point estimate) ± (critical value) * (standard error)

The critical value for a two-sided 90% confidence interval with 169 degrees of freedom (calculated as df = (p₁ * n₁ + p₂ * n₂) / (p₁ + p₂)) can be found using a t-distribution table or calculator.

For a 90% confidence level, the critical value is approximately 1.656.

Using these values, the 90% confidence interval for the difference in proportions is:

-0.02 ± 1.656 * 0.0936

which simplifies to:

-0.1783 to 0.1383

Therefore, we are 90% confident that the true difference in proportions between France and the United States falls between -0.1783 and 0.1383.

Step-by-step explanation:

The probability that each of the final rolls is at least as large as the roll preceding it is \(1/6^6\) or 1/46656.

Given data,

A fair die is rolled n times. We have to find the probability that each of the final rolls is at least as large as the roll preceding it.The probability that each of the final rolls is at least as large as the roll preceding it means the probability of getting each number greater than the preceding one. So, there will be no duplicates.

First, find the total possible outcomes on a fair die. The total possible outcomes on a fair die are 6 because the numbers are 1,2,3,4,5,6. The number of possible outcomes for each roll of the die is 6. Then the total number of possible outcomes on the nth roll of a die is\(6^n\). There will be only one possible sequence in which each of the final rolls is at least as large as the roll preceding it. Let's check it from the following table.

Roller 1Roller 2Roller 3Roller 4Roller 5Roller 61-2-3-4-5-6
