The statement that proves that angle XWY is equal to angle ZYW is

A. If two parallels are cut by a transverse, then alternate interior angles are congruent

Alternate interior angles are a pair of angles that are formed on opposite sides of a transversal line when two parallel lines are intersected by the transversal.

When a transversal intersects two parallel lines, it creates eight angles. Among these angles, the alternate interior angles are located on the inside of the parallel lines and on opposite sides of the transversal.

In a parallelogram, the two opposite sides are parallel to each other hence the line crossing them will lead to formation of alternate interior angles

The correct answer is that the probability of a cash flow being between $16,000 and $19,000 is approximately 18.59%.

To calculate the probability of a cash flow being between $16,000 and $19,000, we can use the standard deviation and assume a normal distribution.

We are given that the average cash flow is $14,000 with a standard deviation of $5,000. These values are necessary to calculate the probability.

The probability of a cash flow falling within a certain range can be determined by converting the values to z-scores, which represent the number of standard deviations away from the mean.

First, we calculate the z-score for $16,000 using the formula: z = (x - μ) / σ, where x is the cash flow value, μ is the mean, and σ is the standard deviation. Plugging in the values, we get z1 = (16,000 - 14,000) / 5,000.

z1 = 2,000 / 5,000 = 0.4.

Next, we calculate the z-score for $19,000: z2 = (19,000 - 14,000) / 5,000.

z2 = 5,000 / 5,000 = 1.

Now that we have the z-scores, we can use a standard normal distribution table or calculator to find the corresponding probabilities.

Subtracting the probability corresponding to the lower z-score from the probability corresponding to the higher z-score will give us the probability of the cash flow falling between $16,000 and $19,000.

Looking up the z-scores in a standard normal distribution table or using a calculator, we find the probability for z1 is 0.6554 and the probability for z2 is 0.8413.

Therefore, the probability of the cash flow being between $16,000 and $19,000 is 0.8413 - 0.6554 = 0.1859, which is approximately 18.59%.

So, the correct answer is that the probability of a cash flow being between $16,000 and $19,000 is approximately 18.59%.

  (x, y) = (36, 54), (68, 102)

Step-by-step explanation:

We observe that y-values are proportional to x-values with a constant of proportionality of 1.5. This is a linear function.

"The next 2 values in the table" presumes we can find the rule for choosing x. For the answer above, we have observed that first differences in x-values increase by powers of 2:

  8-6 = 2

  12 -8 = 4

  20 -12 = 8

So we have chosen the next two x-values to be 16 and 32 more than the one before:

  next x = 20 +16 = 36

  x after that = 36 +32 = 68

That is, the rule for x is ...

  xn = 4 + 2^n

and the rule for y is ...

There are five choices for the first digit, five choices for the second digit, and so on. The total number of 5-digit numbers with repetition is given by the formula: 5 * 5 * 5 * 5 * 5 = 3125. The total number of 5-digit numbers that can be formed using the digits 2, 3, 4, 5, and 6 with repetition is 3125.

The number of ways of choosing r items from n is given by the formula:nCr = n! / r! * (n-r)!

In order to calculate the number of 5-digit numbers that can be formed using the digits 2, 3, 4, 5, and 6 without repetition, we have to use the permutation formula: P(n,r) = n! / (n-r)!

Without Repetition: There are five choices for the first digit and after a digit has been chosen, there are only four remaining digits to choose from.

Therefore, we have five choices for the first digit and four choices for the second digit and so on.

So, the number of 5-digit numbers that can be formed using the digits 2, 3, 4, 5, and 6 without repetition can be calculated as follows: Total number of 5-digit numbers without repetition = 5 * 4 * 3 * 2 * 1= 120.

Therefore, the total number of 5-digit numbers that can be formed using the digits 2, 3, 4, 5, and 6 without repetition is 120.

With Repetition: In the case of repetition, we have five choices for each digit.

Thus, there are five choices for the first digit, five choices for the second digit, and so on.

Therefore, the total number of 5-digit numbers with repetition is given by the formula:5 * 5 * 5 * 5 * 5 = 3125.

Therefore, the total number of 5-digit numbers that can be formed using the digits 2, 3, 4, 5, and 6 with repetition is 3125.

The vertex of the Quadratic function with a y-intercept of (5, 0) and an x-intercept of (0, 80) is located at the point (0, 0).

The vertex of a quadratic function given the y-intercept and x-intercept, we need to determine the axis of symmetry, which is the line that passes through the vertex. The x-coordinate of the vertex will be the midpoint between the x-intercepts, while the y-coordinate will be the same as the y-intercept.

Given that the y-intercept is (5, 0) and the x-intercept is (0, 80), we can determine the x-coordinate of the vertex by finding the midpoint of the x-intercepts. The x-coordinate of the midpoint is simply the average of the x-values:

x-coordinate of vertex = (0 + 0) / 2 = 0 / 2 = 0

Since the y-coordinate of the vertex is the same as the y-intercept, the vertex will have the coordinates (0, 0).

Therefore, the vertex of the quadratic function is (0, 0).

In conclusion, the vertex of the quadratic function with a y-intercept of (5, 0) and an x-intercept of (0, 80) is located at the point (0, 0).

Our assumption that \(sqrt11 − sqrt3\)must be incorrect, and we conclude that \(sqrt11 - sqrt3 > sqrt2.\)

We will use a proof by contradiction method to prove that \(sqrt11 - sqrt3 > sqrt2\)

Suppose that

\(sqrt11 − sqrt3≤ sqrt2.\)

The proof proceeds as follows:

Let's take a square of sides length

\(sqrt11 − sqrt3\)

(as we are supposing\(sqrt11 − sqrt3≤ sqrt2).\)

By the Pythagorean theorem, we get that the diagonal is

\(sqrt((sqrt11 − sqrt3)² + (sqrt11 − sqrt3)²).\)

Therefore, the length of the diagonal is

\(sqrt2 * (sqrt11 - sqrt3)\)

As we supposed,

\(sqrt11 − sqrt3≤ sqrt2,\)

it follows that the length of the diagonal is less than or equal to\(sqrt2 * sqrt2.\)

Consequently, the length of the diagonal is less than or equal to 2.

By a direct computation, the length of the diagonal is\(2sqrt2 - 2sqrt6\)which is approximately equal to 0.098.

Since 0.098 is less than 2, this leads us to a contradiction.

The domain of the function is all positive real numbers, representing the possible diameters of the rope, while the range is all positive real numbers, indicating the potential breaking strengths of the manila rope.

The domain of the function is all positive real numbers since the diameter of a rope cannot be negative or zero. However, it is important to note that in practical terms, the diameter should also have a minimum value, typically determined by the manufacturing specifications or practical constraints.

The range of the function represents the possible breaking strengths of the manila rope. Since the function is defined as z = 8900d^2, where d is the diameter, the breaking strength (z) will always be a positive value. As the diameter increases, the breaking strength also increases, and there is no upper limit to the breaking strength. However, it is essential to consider practical limitations, such as the maximum load capacity of the material used or any physical constraints that may prevent the rope from achieving extremely high breaking strengths.

Answer:

Step-by-step explanation:

For the null hypothesis,

H0: p = 88

For the alternative hypothesis,

Ha: p < 88

Considering the population proportion, probability of success, p = 0.88

q = probability of failure = 1 - p

q = 1 - 0.88 = 0.12

Considering the sample,

Sample proportion, P = x/n

Where

x = number of success = 21

n = number of samples = 32

P = 21/32 = 0.66

We would determine the test statistic which is the z score

z = (P - p)/√pq/n

z = (0.66 - 0.88)/√(0.88 × 0.12)/32 = - 3.83

The corresponding p value would be determined by looking at the normal distribution table for the area below the z score. Therefore,

P value = 0.00006

Answer:

X^2/3

Step-by-step explanation:

With a 95% probability, 62 students should be sampled to be within 0.25 drinks of the population mean.

\(\alpha\) is the level obtained by subtracting 1 from the confidence interval and dividing by 2.

So,

\(\alpha\) = (1 - 0.95) ÷ 2 = 0.25

Now, find z in the Z-table, as z has a p-value of 1 - \(\alpha\).

As a result, z has a p-value of (1 - 0.025) = 0.975

so, z  = 1.96

Now, infer M as follows:

M = z × (σ ÷ √n) where n is the sample size and is σ the population standard deviation.

When M = 1, this is n.

According to the question, the standard deviation is roughly 1.

σ = 1

M = z × (σ ÷ √n)

0. 25 = 1.96 × (1 ÷ √n)

√n = 1.96 × (1 ÷ √n)

Square both sides,

The solutions to the equation 4x^2 - 20x + 25 = 10 are x = 5/2 and x = 3/2.

The equation 4x^2 - 20x + 25 = 10 can be rewritten as 4x^2 - 20x + 15 = 0. To find the solutions to this equation, we can factor it or use the quadratic formula.

The equation factors as (2x - 5)(2x - 3) = 0. Setting each factor equal to zero, we get 2x - 5 = 0 and 2x - 3 = 0. Solving these equations, we find x = 5/2 and x = 3/2.

Using the quadratic formula, which states that for an equation of the form ax^2 + bx + c = 0, the solutions are given by x = (-b ± sqrt(b^2 - 4ac)) / 2a, we can determine the solutions.

In this case, a = 4, b = -20, and c = 15. Substituting these values into the quadratic formula, we get x = (-(-20) ± sqrt((-20)^2 - 4 * 4 * 15)) / (2 * 4), which simplifies to x = (20 ± sqrt(400 - 240)) / 8.

Simplifying further, we have x = (20 ± sqrt(160)) / 8, which becomes x = (20 ± 4sqrt(10)) / 8. Finally, simplifying again, we obtain x = 5/2 ± sqrt(10)/2, which gives us the same solutions as before: x = 5/2 and x = 3/2.

Therefore, the solutions to the equation 4x^2 - 20x + 25 = 10 are x = 5/2 and x = 3/2.

To find the solutions to the equation, we can either factor it or use the quadratic formula. In this case, factoring and using the quadratic formula both yield the same solutions: x = 5/2 and x = 3/2. These values of x satisfy the equation 4x^2 - 20x + 25 = 10 when substituted back into the equation.
