Every quadratic nonresidue of p is a primitive root of p, when p = 2^k + 1 is primeIf p = 2^k + 1 is a prime number, we want to show that every quadratic nonresidue of p is a primitive root of p.

In other words, we aim to prove that if an element x is a quadratic nonresidue modulo p, then it is also a primitive root of p.

Let's assume p = 2^k + 1 is a prime number. To prove that every quadratic nonresidue of p is a primitive root of p, we can use the properties of quadratic residues and quadratic nonresidues.

A quadratic residue modulo p is an element y such that y^((p-1)/2) ≡ 1 (mod p), while a quadratic nonresidue is an element x such that x^((p-1)/2) ≡ -1 (mod p).

Now, let's consider an element x that is a quadratic nonresidue modulo p. We want to show that x is a primitive root of p.

Since x is a quadratic nonresidue, we know that x^((p-1)/2) ≡ -1 (mod p). By Euler's criterion, this implies that x^((p-1)/2) ≡ -1^((p-1)/2) ≡ -1^2 ≡ 1 (mod p).

Since x^((p-1)/2) ≡ 1 (mod p), we can conclude that the order of x modulo p is at least (p-1)/2. However, since p = 2^k + 1 is a prime, the order of x modulo p must be equal to (p-1)/2.

By definition, a primitive root of p has an order of (p-1). Since the order of x modulo p is (p-1)/2, it follows that x is a primitive root of p.

Based on the given information, Abi should choose the Highbrook savings account as it will give her a higher return on her investment at the end of 3 years.

The Highbrook account has a higher initial interest rate of 2.1% for the first year, which is almost double that of the Savemore account. Although the interest rate decreases to 0.95% for the following years, the overall average interest rate for the 3-year period will still be higher than that of the Savemore account.

To calculate the total return on investment for each account, we can use the compound interest formula: A = P(1+r/n)ⁿ, where A is the final amount, P is the principal amount, r is the interest rate, n is the number of times interest is compounded per year, and t is the number of years.

For the Savemore account, Abi will earn 1.25% compound interest each year, so after 3 years, her investment will grow to:

A = 5000(1+0.0125/1)³ = £5,196.09

For the Highbrook account, Abi will earn 2.1% compound interest for the first year and 0.95% for the following 2 years, so after 3 years, her investment will grow to:

A = 5000(1+0.021/1)¹ × (1+0.0095/1)² = £5,269.58

Therefore, Abi should choose the Highbrook savings account as it will give her a higher return on investment of £73.49 after 3 years compared to the Savemore account.

The probability of obtaining exactly the same number of heads as the observed result is 0.0321 if the coin is unfair and 0.9453 if the coin is fair. Comparing these probabilities, it is more likely that the unfair coin was given.

After flipping the coin 30 times, the probability of obtaining the same number of heads or more with a fair coin is 0.5234. This low probability suggests that the coin is likely unfair, which is a confident inference compared to the previous inference after 10 flips.

To determine the probability of obtaining exactly the same number of heads as the observed result, we can use the binomial distribution.

The binomial distribution calculates the probability of obtaining a specific number of successes (in this case, heads) in a fixed number of trials (in this case, coin flips) given a probability of success (probability of getting a head) for each trial.

For the unfair coin, the probability of obtaining exactly the same number of heads as observed is 0.0321. This means that the observed result is relatively rare if the coin is unfair.

For the fair coin, the probability of obtaining exactly the same number of heads as observed is 0.9453. This indicates that the observed result is more likely to occur if the coin is fair.

By comparing these probabilities, we can determine which coin is more likely. Since the probability is higher for the unfair coin (0.0321) compared to the fair coin (0.9453), it is more likely that the unfair coin was given.

Next, to assess the probability of obtaining the same number of heads or more with a fair coin, we calculate the cumulative probability. This is done by summing up the probabilities of obtaining the observed number of heads and all greater numbers of heads.

In this case, the probability is 0.5234, which represents the likelihood of obtaining the observed result or more extreme results with a fair coin.

A low probability, such as 0.5234, suggests that the observed result is highly unlikely to occur by chance alone if the coin is fair. Therefore, we can confidently infer that the coin is likely unfair based on this low probability. This inference is more confident compared to the previous inference made after 10 flips of the coin.

Diana is three years younger than Eduardo, and Eduardo is four years older than Chad, while Faye is three years older than Chad;

we can come up with a way to solve this problem using a system of linear equations.

As such, let's use the following variables for their ages:

Let D be the age of DianaLet E be the age of EduardoLet C be the age of ChadLet F be the age of FayeBased on the problem statement, we have that:

D = E - 3 (Diana is three years younger than Eduardo)

E = C + 4 (Eduardo is four years older than Chad)

F = C + 3 (Faye is three years older than Chad)

Furthermore, we know that Diana is 14 years old; hence we can substitute that in the equation for Diana's age:

14 = E - 3By adding 3 to both sides of the equation, we get:

E = 17Substituting this value of E in the equation for Faye's age, we get:

F = C + 3Since we don't know Chad's age (i.e., C), we cannot directly calculate Faye's age.

However, we can use another piece of information from the problem statement to determine Chad's age: Eduardo is four years older than Chad.

We know that Eduardo is 17 years old (from above), so Chad must be 17 - 4 = 13 years old.Now we can substitute this value of Chad's age in Faye's equation:

F = C + 3 = 13 + 3 = 16

Therefore, Faye is 16 years old.

Answer:

That's the answer up there, root 55

The diameter of the circle is approximately 60 inches.

To explain further, we can use the formula relating the central angle of a sector to the length of its intercepted arc. The formula states that the length of the intercepted arc (A) is equal to the radius (r) multiplied by the central angle (θ) in radians.

In this case, we are given the central angle (225 degrees) and the length of the intercepted arc (30π inches).

To find the diameter (d) of the circle, we need to find the radius (r) first. Since the length of the intercepted arc is equal to the radius multiplied by the central angle, we can set up the equation 30π = r * (225π/180). Simplifying this equation gives us r = 20 inches.

The diameter of the circle is twice the radius, so the diameter is equal to 2 * 20 inches, which is 40 inches. Therefore, the diameter of the circle is approximately 60 inches.

In summary, by using the formula for the relationship between central angle and intercepted arc length, we can determine the radius of the circle. Doubling the radius gives us the diameter, which is approximately 60 inches.

The total resistance for the current is 432900 ohms.

The obstruction to current flow in an electrical circuit is measured by resistance. The Greek letter omega () represents the unit of measurement for resistance, known as ohms. Georg Simon Ohm (1784–1854), a German scientist who investigated the connection between voltage, current, and resistance, is the name given to the unit of resistance. Ohm's Law is attributed to him as its creator.

The power in parallel connection is calculated as:

Peq = P1 + P2 / (P1)(P2)

Peq = 250 + 150 / (250)(150)

For P3 and P4:

Peq2 = P3 + P4 / (P3)(P4)

Peq2 = 250 + 150 / (250)(150)

Now, the two are in series thus,

P = 250 + 150 / (250)(150) + 250 + 150 / (250)(150)

P = 2(250 + 150 / (250)(150))

P = 0.0213

The power formula is given as:

P = V(V) / R

0.0231 = (100)(100)/R

R = 432900 ohms.

Hence, the total resistance for the current is 432900 ohms.

Here,

1.1. The statement omits details about the truck's loan term. Therefore, without more details, we are unable to respond to this query.

1.2. Assume that the truck's loan period is n years and that the contractor borrowed P dollars at an annual interest rate of r to buy the water tanker.

M is calculated as (r * P * (1 + r)n) / ((1 + r)n - 1)

5 years + 60 months Equals n

r = 5% / 12 = 0.004166667 (weekly interest rate) (monthly interest rate)

P = $100,000

=> M = (0.004166667 * $100,000 * (1 + 0.004166667)^60) / ((1 + 0.004166667)^60 - 1)

If Bob only fixes 50 computers, his total loss is $3,750.

The total loss results from the negative difference between the total revenue and the total costs.

The total costs consist of variable and fixed costs.

The result is a loss when the total costs exceed the total revenue.  This result becomes a profit or income when the total revenue exceeds the total costs.

Equipment = $5,000

Premises = $6,000

Advertising = $4,000

Total fixed costs = $15,000

Variable cost per unit = $25

Selling price per unit = $250

Total number of computers fixed = 50

The total variable cost for 50 units = $1,250 (50 x $25)

The total costs (fixed and variable) = $16,250

The sales revenue for 50 units = $12,500 (50 x $250)

Loss = $3,750 ($12,500 - $16,250)
