The limit does not exist.

In order for such a limit to occur, the fraction \(\frac{x^{2} }{x^{2} +y^{2} }\) must be comparable to the same value \(L\), regardless of the way we take to get there \((0,0)\).

Try approaching \((0,0)\) along the x-axis.

This means setting \(y=0\) and finding the limit \(lim_{x-0} \frac{x^{2} }{x^{2} +y^{2} }\).

We obtain:

\(lim_{x-0,y=0}\frac{x^{2} }{x^{2} +y^{2} } =lim_{y=0}}\frac{x^{2} }{x^{2} +0 }\\=lim_{x-0}} \frac{x^{2} }{x^{2} } \\\\=lim_{x-0}}1\\=1\)

Now evaluate approaching \((0,0)\) along the y-axis.

This means setting \(x=0\) and finding the limit \(lim_{y-0} \frac{x^{2} }{x^{2} +y^{2} }\).

\(lim_{y-0,x-0} \frac{x^{2} }{x^{2} +y^{2} } =lim_{y-0} \frac{0}{0+y^{2} } \\=lim_{y-0} \frac{0}{y^{2} } \\=lim_{y-0} 0\\=0\)

Approaching the origin via these two methods results in distinct limits.

\(lim_{x-0,y-0} \frac{x^{2} }{x^{2} +y^{2} }\) ≠ \(lim_{y-0,x-0}\frac{x^{2} }{x^{2} +y^{2} }\)

Therefore the limit does not exist.

Using the binomial probability function formula, the probability that the sample contains exactly 2 graduate students is 0.215.

The probability that the sample of 5 students contains exactly 2 graduate students using the binomial probability function can be determined by using the formula below:

P(X = k) = (n choose k) * p^k * (1 - p)^(n - k)

where n is the sample size, k is the number of successes, p is the probability of success, and (n choose k) = n! / (k! * (n - k)!) denotes the number of ways to choose k items from a set of n items.

Using the formula above and the information given, the probability of the sample containing exactly 2 graduate students can be calculated as follows:

P(X = 2) = (5 choose 2) * (0.32)² * (1 - 0.32)^(5 - 2) = 0.215

Where (5 choose 2) = 5! / (2! * (5 - 2)!) = 10 is the number of ways to choose 2 graduate students from a sample of 5 students.

The leftmost vertex is (0, 4), and the rightmost vertex is (2.5, 0). Therefore, the smallest x-value (a, b) is 0, and the largest x-value (a, b) is 2.5.

The extreme points of the feasible region in linear programming are the vertices of the polygon formed by the constraints. The smallest x-value is the leftmost vertex, and the largest x-value is the rightmost vertex.

The extreme points of the feasible region are the vertices of the polygon formed by the constraints of the linear programming problem. Each vertex represents a unique combination of values for the decision variables that satisfies all of the constraints.

The smallest x-value (a, b) of the extreme points corresponds to the leftmost vertex of the feasible region, and the largest x-value (a, b) corresponds to the rightmost vertex of the feasible region.

For example, consider the following linear programming problem:

Maximize 3x + 2y

Subject to:

x + y ≤ 4

2x + y ≤ 5

x, y ≥ 0

The feasible region is a polygon with vertices at (0, 0), (0, 4), (1.5, 2.5), and (2.5, 0). The leftmost vertex is (0, 4), and the rightmost vertex is (2.5, 0). Therefore, the smallest x-value (a, b) is 0, and the largest x-value (a, b) is 2.5.

Step-by-step explanation: Za Warudo

The answer is D

Step-by-step explanation:

For the given equation based on the word problem the possible values for the number are -2 and 6.

Let the number be x. The word problem yields the equation 2x^2 - 8x = 24. To find all possible values for the number, we use the equation and solve for x.

Step 1: Subtract 24 from both sides of the equation to get 2x^2 - 8x - 24 = 0.

Step 2: Factorize the equation

2x^2 - 8x - 24 = 0

x^2 - 4x - 12 = 0

x^2 - 6x + 2x - 12 = 0

x(x - 6) + 2(x - 6) = 0

(x - 6)(x + 2) = 0

Step 3: Set each factor equal to zero and solve for x.

x + 2 = 0

x = -2

x - 6 = 0

x = 6

Step 4: The possible values for the number are -2 and 6.

A random sample is a sample that is drawn from a population in such a way that each member of the population has an equal chance of being selected. The mean is a measure of central tendency that represents the average value of a set of data.

In this scenario, a simple random sample of size n was drawn from a population that is normally distributed. The sample mean, X, was found to be 112, and the sample standard deviation, s, was found to be 10.

(a) To construct an 80% confidence interval about us if the sample size, n, is 13, we can use the formula:

CI = X ± t(α/2, n-1) * s/√n

where t(α/2, n-1) is the critical value for the t-distribution with (n-1) degrees of freedom and α is the level of significance. For an 80% confidence interval, α = 0.2 and t(α/2, n-1) = 1.340. Thus, the confidence interval is:

CI = 112 ± 1.340 * 10/√13
CI = (103.76, 120.24)

(b) To construct an 80% confidence interval about p if the sample size, n, is 24, we can use the formula:

CI = p ± z(α/2) * √(p(1-p)/n)

where z(α/2) is the critical value for the standard normal distribution and p is the sample proportion. Since the population is normally distributed, we can assume that the sample proportion is also normally distributed. For an 80% confidence interval, α = 0.2 and z(α/2) = 1.282. Thus, the confidence interval is:

CI = 112/24 ± 1.282 * √(112/24 * (1-112/24)/24)
CI = (0.38, 0.68)

(c) To construct a 95% confidence interval about p if the sample size, n, is 13, we can use the same formula as in (b), but with α = 0.05 and z(α/2) = 1.96. Thus, the confidence interval is:

CI = 112/13 ± 1.96 * √(112/13 * (1-112/13)/13)
CI = (0.38, 0.78)

(d) Yes, we could have computed the confidence intervals using the formulas provided, as long as the assumptions of normality and independence were met. However, if the sample size was small or the population was not normally distributed, we would need to use different methods, such as the t-distribution or non-parametric tests.

The probability of Roger selling a zucchini bread as the next loaf is 4/21.

What is probability?

Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, with 0 representing an impossible event and 1 representing a certain event. The probability of an event is calculated by dividing the number of ways the event can occur by the total number of possible outcomes.

The probability of Roger selling a zucchini bread as the next loaf can be found by dividing the number of zucchini breads sold by the total number of breads sold so far.

The total number of breads sold so far is:

11 (banana) + 8 (zucchini) + 9 (cranberry) + 14 (blueberry) = 42

The number of zucchini breads sold is 8.

So the probability that the next loaf Roger sells will be zucchini bread is:

8/42 = 4/21

Therefore, the probability of Roger selling a zucchini bread as the next loaf is 4/21.

Answer:

f(x) = 8(x-3)

Step-by-step explanation:

F^ -1 ( x) = x/8 +3

Let y = x/8+3

To find the inverse

Exchange x and y

x = y/8+3

Solve for y

x-3 = y/8+3-3

x-3 = y/8

Multiply each side by 8

8(x-3) = y/8 * 8

8(x-3) = y

The inverse of the inverse is the function so

f(x) = 8(x-3)

Answer:

\(\boxed{f(x) = 8(x-3)}\)

Step-by-step explanation:

\(y=\frac{x}{8} +3\)

Switch variables.

\(x=\frac{y}{8} +3\)

Make y as subject.

Subtract 3 from both sides.

\(x-3=\frac{y}{8}\)

Multiply both sides by 8.

\(8(x-3)=y\)

The triangle JKL is similar to triangle MNL by AA similarity and all three sides of the triangle are equal, so JKL = MNL.

One of the fundamental shapes in geometry is represented by the symbol Δ and consists of three connected vertices. Any one of a triangle's three sides can serve as its base, however typically the bottom side is used.

Given:

JK || MN and  L is the midpoint of JM,

As the line JK || MN  then,

∠ MNL = ∠ JKL (The alternate angle of the parallel line are equal)

∠ LMN = ∠ LJK (The alternate angle of the parallel line are equal)

∠ JLK = ∠ NLM (The corresponding  angle of the parallel line are equal)

Thus, all the sides will also be equal as the angles are equal.

Hence, the area will also be equal.
