The probability of making the first sale on the fifth call is approximately 0.078.Indicated probabilities using the geometric distribution, the Poisson distribution, or the binomial distribution

The problem can be solved using the geometric distribution, as we are interested in the probability of the first success occurring on a specific trial. In this case, the probability of making a sale on any given telephone call is 0.17.

(a) To find the probability of making the first sale on the fifth call, we can use the formula for the geometric distribution:

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

where P(X = k) represents the probability of the first success occurring on the k-th trial, p is the probability of success on a single trial, and (1 - p)^(k-1) represents the probability of failure on the first k-1 trials.

Substituting the given values into the formula, we have:

P(X = 5) = (1 - 0.17)^(5-1) * 0.17

        ≈ 0.78 * 0.17

        ≈ 0.078

Therefore, the probability of making the first sale on the fifth call is approximately 0.078.

The angle of rotation at the point \(\(z_0 = 2i + 1\)\) when \(\(w = z^2\)\) is \(\(2\arctan(2)\),\) which is approximately 1.107 radians or 63.43 degrees.

To determine the angle of rotation at the point \(\(z_0 = 2i + 1\)\) when \(\(w = z^2\),\) we can follow these steps:

1. Express \(\(z_0\)\) in polar form: To find the polar form of \(\(z_0\)\), we need to calculate its magnitude \((\(r_0\))\) and argument \((\(\theta_0\))\). The magnitude can be obtained using the formula \(\(r_0 = |z_0| = \sqrt{\text{Re}(z_0)^2 + \text{Im}(z_0)^2}\)\):

\(\[r_0 = |2i + 1| = \sqrt{0^2 + 2^2 + 1^2} = \sqrt{5}\]\)

  The argument \(\(\theta_0\)\) can be found using the formula \(\(\theta_0 = \text{arg}(z_0) = \arctan\left(\frac{\text{Im}(z_0)}{\text{Re}(z_0)}\right)\)\):

\(\[\theta_0 = \text{arg}(2i + 1) = \arctan\left(\frac{2}{1}\right) = \arctan(2)\]\)

2. Find the polar form of \(\(w\)\): The polar form of \(w\) can be expressed as \(\(w = |w|e^{i\theta}\)\), where \(\(|w|\)\) is the magnitude of \(\(|w|\)\) and \(\(\theta\)\) is its argument. Since \((w = z^2\)\), we can substitute z with \(\(z_0\)\) and calculate the polar form of \(\(w_0\)\)using the values we obtained earlier for \(\(z_0\)\):

 \(\[w_0 = |z_0|^2e^{2i\theta_0} = \sqrt{5}^2e^{2i\arctan(2)} = 5e^{2i\arctan(2)}\]\)

3. Determine the argument of \(\(w_0\):\) To find the argument \(\(\theta_w\)\) of \(\(w_0\)\), we can simply multiply the exponent of \(e\) by 2:

  \(\[\theta_w = 2\theta_0 = 2\arctan(2)\]\)= 1.107 radians

Therefore, the angle of rotation at the point \(\(z_0 = 2i + 1\)\) when \(\(w = z^2\)\) is \(\(2\arctan(2)\).\)

And you've been given all of those values except QR.  Substituting in the values from the paragraph, we have:

Multiplying by 42, you'd get QR = 102.

(a) The function f(x, y) does not have a limit at (0,0). (b) No information is provided to determine the limit for f2(x, y).

(a) For the function f(x, y) = 5ry²/(3x² + y²), we can analyze the behavior as (x, y) approaches (0,0). Since the denominator 3x² + y² becomes zero as (x, y) approaches (0,0), we cannot directly evaluate the function at this point. However, by considering the parabola z = -y², we can observe that the function does not approach a specific value and thus does not have a limit at (0,0).

(b) The function f2(x, y) = Vel + Vsin(y) is not well-defined as no information or context is provided for the variables Vel, V, and U. Without this information, it is not possible to determine the limit of the function at (0,0) or any other point.

Therefore, for (a), the function f(x, y) does not have a limit at (0,0), and for (b), no information is given to determine the limit for f2(x, y).

I am not entirely clear as to if throwing fewer than 6 darts is allowed, but we'd only need it for c.

The reason we need to throw fewer than 6 for c. is that all the scores are odd, so adding 6 odd scores will always give an even score.

We can create the scores by throwing for the highest score that lets us throw the remaning darts at 1 or more.

The number of 100.

To find:

The given number as an exponential expression with 10 as the base.

Solution:

We have,

Given number = 100

It can be written as

\(100=10\times 10\)

\(100=10^{1+1}\)                   \([\because a^m\cdot a^n=a^{m+n}]\)

\(100=10^2\)

Here, base is 10 and exponent is 2.

Therefore, the given number can be written as \(10^2\).

This indicates that the population variance is, with 99% confidence, between 8.53 and 9.35.

The chi-square distribution can be used to compute the population variance's 99% confidence interval estimate based on a sample standard deviation of 12 and a sample size of 10.

The confidence interval's formula is:

(s² / X²) * (n - 1) < σ² < (s² / X²) * n

Where X² is the upper percentile of the chi-square distribution with n-1 degrees of freedom, n is the sample size (10), and s² is the sample variance  (12² = 144).

Using a chi-square table with 9 degrees of freedom and a 99% level of confidence, we can determine that  X² = 16.919 As a result,

the population variance's confidence interval is:

(144 / 16.919) * (10 - 1) < σ² < (144 / 16.919) * 10

(8.53 < σ² < 9.35)

This indicates that the population variance is, with 99% confidence, between 8.53 and 9.35.

The measure of angle BAC in the given shaded right triangle is approximately 45 degrees.

Let's start by labeling the sides of the triangle. We are given that BC = 3, AC = 3, and BA = 4.24. We can use the Pythagorean theorem to find the length of the missing side, which is opposite the right angle at C. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In this case, we have:

BA² = BC² + AC²

Substituting the given values, we get:

4.24² = 3² + 3²

Simplifying and solving for 4.24², we get:

4.24² = 18.0176

Taking the square root of both sides, we get:

4.24 ≈ √18.0176

Now we can use the trigonometric ratio of sine to find the measure of angle BAC. The sine of an angle in a right triangle is defined as the ratio of the length of the side opposite the angle to the length of the hypotenuse. In other words:

sin(BAC) = AC / BA

Substituting the given values, we get:

sin(BAC) = 3 / 4.24

Using a calculator to evaluate the right-hand side, we get:

sin(BAC) ≈ 0.7071

Finally, we can use the inverse sine function (also called arcsine) to find the measure of angle BAC. The inverse sine function takes a ratio and gives us the angle whose sine is that ratio. In other words:

BAC = arcsin(sin(BAC))

Substituting the calculated value of sin(BAC), we get:

BAC = arcsin(0.7071)

Using a calculator to evaluate the right-hand side, we get:

BAC ≈ 45°

The area of the lawn watered by the sprinkler is approximately 3.311 square feet.

To determine the area of the lawn watered by the sprinkler, we need to calculate the sector area of the circle covered by the sprinkler's rotation.

First, let's find the radius of the circle. The distance from the sprinkler to the edge of the water projection is 4.1 ft. Since the sprinkler rotates 115°, it covers one-fourth (90°) of the circle.

To find the radius, we can use the trigonometric relationship in a right triangle formed by the radius, half of the water projection (2.05 ft), and the adjacent side (distance from the center to the edge). The adjacent side is found using cosine:

cos(angle) = adjacent / hypotenuse

cos(90°) = 2.05 ft / radius

Solving for the radius:

radius = 2.05 ft / cos(90°) = 2.05 ft

Now that we have the radius, we can calculate the area of the sector covered by the sprinkler:

sector area = (angle / 360°) * π * radius^2

= (115° / 360°) * π * (2.05 ft)^2

Calculating this expression:

sector area ≈ 0.318 * π * (2.05 ft)^2 ≈ 3.311 ft²

The inequalities that represent the regular price of eyeglass frames will be 0.4r ≤ 120 and r ≥ 4(360/5).

If we let r represent the regular price of the eyeglass frames, then we can write the following two inequalities based on the given information:

0.4r ≤ 120

This inequality represents the fact that the lowest regular price for the eyeglass frames is $120. We use 0.4 because a 60% discount means that the price paid is 40% of the regular price.

Also, r ≥ 4(360/5) as this inequality represents the fact that the highest regular price for the eyeglass frames is $360. We use 4(360/5) because a 75% discount means that the price paid is 25% of the regular price, which is equivalent to multiplying the regular price by 0.25. Then, 4 times that amount gives us the regular price, which is $360 in this case.
