Ms. Khan wants to add x feet onto each side of an existing patio, then the area of the existing patio is (x-2)² square feet.
Define square feet?
In the United States, Canada, China, and the United Kingdom, the square foot is a commonly used imperial measure of area. Its emblem is a straightforward square with a vertical line cutting it in half .
The Imperial system uses a combination of feet, inches, miles, and gallons.
So,
we can write (x-2)² = x²+14x+48.
Expanding the left side gives us x²-4x+4 = x²+14x+48.
Simplifying gives us 18x = 44.
Therefore, x = 11/4.

if p = 2^k + 1 is prime, show that every quadratic nonresidue of p is a primitive root of p.
Answers
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.

A college has 19 engineering students for every 81 students enrolled. if the college has 750 students, approximately how many are engineering students
Answers
The total number of engineering students is 176 approximately among the 750 students enrolled in the college by using the proportionate formula.
It is mentioned here that a college has 19 students of engineering for every 81 students who got enrolled.
Therefore the ratio of engineering students to total number of students is as follows:
No. of engineering students = 19
Total number of students = 81
Ratio = \(\frac{19}{81}\)
Now if the total number of students that the college has is 750 then the number of engineering students can be found by using the proportionate formula as the ratio of the engineering to the total students will remain same.
Total number of students = 750
Let the number of engineering students be y
Ratio = \(\frac{y}{750}\)
Comparing it with the above ratio and using the proportionate formula,
\(\frac{19}{81} = \frac{y}{750}\)
⇒ y = \(\frac{19*750}{81}\)
⇒ y = 175.925
So approximately 176 were the engineering students among 750 students enrolled.

In ΔEFG, the measure of ∠G=90°, the measure of ∠F=47°, and GE = 50 feet. Find the length of EF to the nearest tenth of a foot
Answers
The length of EF in triangle EFG, to the nearest tenth of a foot, is approximately 50.8 feet.
To find the length of EF in triangle EFG, we can use trigonometric ratios based on the given angle measures.
Since ∠G is a right angle (90°), we can use the trigonometric ratio of tangent (tan) to determine the length of EF.
tan(∠F) = opposite/adjacent
In this case, EF is the opposite side and GE is the adjacent side to ∠F.
tan(∠F) = EF/GE
We can rearrange the equation to solve for EF:
EF = tan(∠F) * GE
Substituting the given values:
EF = tan(47°) * 50
Using a calculator, we find:
EF ≈ 50.790
Rounding to the nearest tenth of a foot:
EF ≈ 50.8 feet
Therefore, the length of EF in triangle EFG, to the nearest tenth of a foot, is approximately 50.8 feet.

The expectancy theory is based on the beliefs of expectancy, instrumentality, and valence, which together shape an individual's motivation and decision-making process in the workplace. These beliefs can have different probabilities associated with them, influencing the level of motivation and engagement individuals exhibit.
(1) The expectancy theory attempts to answer the question of what motivates individuals in the workplace and why they choose to engage in certain behaviors. It explores the relationship between an individual's effort, performance, and outcomes in a work setting.
(2) The theory is built on three probabilistic beliefs, namely expectancy, instrumentality, and valence.
(3) Expectancy refers to an individual's belief that their effort will lead to a specific level of performance. It is influenced by factors such as self-confidence, past experiences, and the availability of necessary resources.
(4) Instrumentality is the belief that performance will be rewarded with certain outcomes or consequences. It depends on factors like trust in the reward system, credibility of management, and perceived fairness of the reward distribution.
(5) Valence represents the value or attractiveness an individual places on the anticipated outcomes. It reflects personal preferences and includes both intrinsic and extrinsic motivators.
Each belief can have a range of probability values associated with it. For example, in the case of expectancy, it could range from low to high, indicating varying levels of confidence in the relationship between effort and performance. Similarly, instrumentality could range from low to high, representing the extent to which individuals believe that performance will result in desirable outcomes. Valence can also vary from negative to positive, depending on how individuals perceive the desirability of the outcomes.
Therefore, the expectancy theory is based on the beliefs of expectancy, instrumentality, and valence, which together shape an individual's motivation and decision-making process in the workplace. These beliefs can have different probabilities associated with them, influencing the level of motivation and engagement individuals exhibit.

A subspace is a special type of set within a vector space that has the same properties as the larger vector space.
In order to determine if a subset of a vector space is a subspace, we must check if it satisfies certain conditions.
The first condition is that the subset must contain the zero vector.
The second condition is that the subset must be closed under addition.
The third condition is that the subset must be closed under scalar multiplication.

a random sample of 39 students is taken. the population of students spends an average of $10.2 a day on dinner. the standard deviation is $1.4. what is the probability that the sample mean will be between $10 and $10.2?
Answers
The probability that the sample mean will be between $10 and $10.2 is approximately 0.3144 or 31.44%.
To calculate the probability that the sample mean will be between $10 and $10.2, we need to use the properties of the sampling distribution of the sample mean. Under certain assumptions (e.g., a large sample size or normality of the population distribution), the sampling distribution of the sample mean follows a normal distribution.
Given that the population mean is $10.2 and the population standard deviation is $1.4, we can use the Central Limit Theorem to approximate the distribution of the sample mean. The Central Limit Theorem states that for a sufficiently large sample size, the sampling distribution of the sample mean will be approximately normal, regardless of the shape of the population distribution.
In this case, the sample size is 39, which is considered reasonably large. Therefore, we can approximate the distribution of the sample mean as a normal distribution with a mean of $10.2 and a standard deviation of σ/√n, where σ is the population standard deviation and n is the sample size.
The standard deviation of the sample mean is calculated as follows:
Standard deviation of the sample mean = σ/√n = 1.4/√39 ≈ 0.224
To find the probability that the sample mean will be between $10 and $10.2, we need to calculate the z-scores for both values and then use the standard normal distribution (z-distribution) to find the probability.
The z-score for $10 is calculated as follows:
z1 = (10 - 10.2) / (0.224) ≈ -0.893
The z-score for $10.2 is calculated as follows:
z2 = (10.2 - 10.2) / (0.224) = 0
Now, we can use a standard normal distribution table, calculator, or software to find the probabilities associated with these z-scores.
The probability that the sample mean will be between $10 and $10.2 is equal to the probability of having a z-score between -0.893 and 0.
Using a standard normal distribution table or calculator, the probability can be calculated as follows:
P(-0.893 ≤ Z ≤ 0) ≈ P(Z ≤ 0) - P(Z ≤ -0.893)
Looking up the values in a standard normal distribution table or using a calculator, we find:
P(Z ≤ 0) ≈ 0.5 (probability of being less than or equal to the mean)
P(Z ≤ -0.893) ≈ 0.1856
Therefore,
P(-0.893 ≤ Z ≤ 0) ≈ 0.5 - 0.1856 ≈ 0.3144
Hence, the probability that the sample mean will be between $10 and $10.2 is approximately 0.3144 or 31.44%.
