Two numbers have a sum of 2 and a difference of -16. What are the numbers

I'm 99% sure your back in your starting position

In parallelogram ABCD, ∠b = 55°; ∠d = 55. So, the correct answer is (a).

We know that opposite angles of a parallelogram are congruent. In another words, opposite angles of  parallelogram are equal. Therefore, we equate the angle B and angle D to each other and solve.

angle B = angle D

2n + 15 = 3n - 15

n = 30

The value of n is 30.

Now we can find the measures of angles B and D:

angle B = 2n + 15 = 2(30) + 15 = 75 degrees

angle D = 3n - 15 = 3(30) - 15 = 75 degrees

Therefore, the answer is (a) ∠b = 55°; ∠d = 55

Step-by-step explanation:

Answer:

Yes they both are equal

1) The amplitude c+ is c+l

2) The expectation value is 0

3) The uncertainty ΔSX is √(3/7) c+.

Now, we know that any wave function can be written as a linear combination of two spin states (up and down), which can be written as:

Ψ = c+ |+> + c- |->

where c+ and c- are complex constants, and |+> and |-> are the two orthogonal spin states such that Sx|+> = +1/2|+> and Sx|-> = -1/2|->.

Hence, we can write the given wave function as:Ψ = c+|+> + i/√7|->

Now, we know that the given wave function has been defined in Sx basis, and not in the basis of |+> and |->.

Therefore, we need to write |+> and |-> in terms of |l> and |r> (where |l> and |r> are two orthogonal spin states such that Sy|l> = i/2|l> and Sy|r> = -i/2|r>).

Now, |+> can be written as:|+> = 1/√2(|l> + |r>)

Similarly, |-> can be written as:|-> = 1/√2(|l> - |r>)

Therefore, the given wave function can be written as:Ψ = (c+/√2)(|l> + |r>) + i/(√7√2)(|l> - |r>)

Therefore, we can write:c+|l> + i/(√7)|r> = (c+/√2)|+> + i/(√7√2)|->

Comparing the coefficients of |+> and |-> on both sides of the above equation, we get:

c+/√2 = c+l/√2 + i/(√7√2)

Therefore, c+ = c+l

The amplitude c+ is a real number and is equal to c+l

The expectation value of the operator Sx is given by: = <Ψ|Sx|Ψ>

Now, Sx|l> = 1/2|r> and Sx|r> = -1/2|l>

Hence, = (c+l*) + (c+l) + (i/√7) - (i/√7)(c+l*)= -i/√7(c+l*) + i/√7(c+l)= 2i/√7 Im(c+)

As c+ is a real number, Im(c+) = 0

Therefore, = 0

The uncertainty ΔSX in the state |Ψ> is given by:

ΔSX = √( - 2)

where = <Ψ|Sx2|Ψ>and2 = (<Ψ|Sx|Ψ>)2

Now, Sx2|l> = 1/4|l> and Sx2|r> = 1/4|r>

Hence, = (c+l*) + (c+l) + (i/√7) - (i/√7)(c+l*)= 1/4(c+l* + c+l) + 1/4(c+l + c+l*) + i/(2√7)(c+l* - c+l) - i/(2√7)(c+l - c+l*)= = 1/4(c+l + c+l*)

Now,2 = (2i/√7)2= 4/7ΔSX = √( - 2)= √(1/4(c+l + c+l*) - 4/7)= √(3/14(c+l + c+l*))= √(3/14 * 2c+)= √(3/7) c+

A 24-hour collection provides a more comprehensive and reliable assessment of certain values.

A 24-hour collection is a better indicator of some values than a random specimen because it provides a more comprehensive and representative sample of the specific substance or parameter being measured.

It captures variations in levels throughout the day and allows for the detection of fluctuations that may not be captured by a single random specimen.

A 24-hour collection involves collecting samples over a full day, typically for substances such as urine or hormones. This method provides a more accurate representation of the average levels of the substance being measured. It takes into account the diurnal rhythm or cyclical variations that may occur throughout the day.

For example, hormone levels often fluctuate throughout the day, with different peaks and troughs at specific times.

By collecting samples at regular intervals over a 24-hour period, a more accurate picture of the average hormone levels can be obtained, allowing for a better assessment of hormonal imbalances or abnormalities.

In contrast, a random specimen may only capture a snapshot of the substance's level at a specific moment, which may not be representative of the overall pattern.

Fluctuations in levels throughout the day can be missed, leading to potential inaccuracies or misinterpretation of the data.

Therefore, a 24-hour collection provides a more comprehensive and reliable assessment of certain values by capturing variations and trends over time, making it a better indicator than a single random specimen.

a. The probability of exactly two thefts occurring in a minute is approximately 0.139.

b. The probability of no thefts occurring in a minute is approximately 0.026.

c. The probability of three or fewer thefts occurring in a minute is approximately 0.398.

a. The probability of exactly two thefts occurring in a minute can be calculated using the Poisson probability distribution. With an average rate of 3.6 thefts per minute, the probability is given by:

P(X = 2) = (e^(-λ) * λ^2) / 2!

where λ is the average rate of thefts per minute.

Plugging in the values, we have:

P(X = 2) = (e^(-3.6) * 3.6^2) / 2! ≈ 0.139

Therefore, the probability of exactly two thefts occurring in a minute is approximately 0.139.

b. The probability of no thefts occurring in a minute can be calculated using the Poisson probability distribution as well. The formula is:

P(X = 0) = e^(-λ)

Substituting the average rate of thefts per minute

P(X = 0) = e^(-3.6) ≈ 0.026

Thus, the probability of no thefts occurring in a minute is approximately 0.026.

c. The probability of three or fewer thefts occurring in a minute can be calculated by summing the probabilities of having 0, 1, 2, and 3 thefts. Using the Poisson probability distribution, we can calculate each individual probability and sum them up:

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

Substituting the values, we get:

P(X ≤ 3) ≈ 0.026 + 0.094 + 0.139 + P(X = 3)

We can calculate P(X = 3) using the Poisson formula as before:

P(X = 3) = (e^(-3.6) * 3.6^3) / 3!

Substituting the value:

P(X = 3) ≈ 0.139

Therefore:

P(X ≤ 3) ≈ 0.026 + 0.094 + 0.139 + 0.139 ≈ 0.398

Hence, the probability of three or fewer thefts occurring in a minute is approximately 0.398.

The value of the gift in 11 years, when deposited in an account paying 5 percent, will be $26,781.99.

To calculate the future value of the gift, we can use the formula for compound interest:

Future Value = Present Value * (1 + Interest Rate)^Time

Given that the present value is $15,500, the interest rate is 5 percent (0.05), and the time is 11 years, we can plug these values into the formula:

Future Value = $15,500 * (1 + 0.05)^11

= $15,500 * (1.05)^11

= $15,500 * 1.747422051

= $26,781.99

Therefore, the value of the gift in 11 years, when compounded at an annual interest rate of 5 percent, will be approximately $26,781.99.

In this calculation, we assume that the interest is compounded annually. Exhibit 1-A might provide additional information, such as the compounding frequency (e.g., quarterly, monthly) or any other specific details about the interest calculation. It's important to note that compounding more frequently within a year would result in a slightly higher future value due to the effect of compounding.

Therefore, the degree of the resulting polynomial is m + n when two polynomials of degree m and n are multiplied together.

What is polynomial?

A polynomial is a mathematical expression consisting of variables and coefficients, which involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents. Polynomials can have one or more variables and can be of different degrees, which is the highest power of the variable in the polynomial.

Here,

When two polynomials are multiplied, the degree of the resulting polynomial is the sum of the degrees of the original polynomials. In other words, if the degree of the first polynomial is m and the degree of the second polynomial is n, then the degree of their product is m + n.

This can be understood by looking at the product of two terms in each polynomial. Each term in the first polynomial will multiply each term in the second polynomial, so the degree of the resulting term will be the sum of the degrees of the two terms. Since each term in each polynomial has a degree equal to the degree of the polynomial itself, the degree of the resulting term will be the sum of the degrees of the two polynomials, which is m + n.
