Consider u = {x|x is a negative real number}. which is an empty set? {x|x ∈ u and x has a negative cube root} {x|x ∈ u and x has a negative square root} {x|x ∈ u and x is equal to the product of a positive number and â€""1} {x|x ∈ u and x is equal to the sum of one negative and one positive number}

Answer:

10 . 44 ft

Step-by-step explanation:

sin 50 = opposite leg / hypotenuse = 8 / x

8 / sin 50 = x    = 10 .44  ft

Answer:

10.433cm

Step-by-step explanation:

Using SOH from TOACAHSOH,

\(sin50deg = \frac{opposite}{hypotenuse} \)

From here we know there the opposite is 8ft (height of the ring) and hypotenuse is what we want to find, distance between you and the ring.

\(sin(50) = \frac{8}{x} \\ x \sin(50) = 8 \\ x = \frac{8}{ \sin(50) } \\ x = 10.443cm(rounded \: to \: 5sf)\)

A. The expected value for Jeremy's initial distribution is:

E(X) = (18/38)$20 + (18/38)(-$20) + (2/38)(-$20) = -$0.53

B. This means that on average, Jeremy can expect to lose $0.53 per round played in the long run.

C. The expected value for Jeremy's new distribution, where he bets $40 per round, is:

E(X) = (18/38)$40 + (18/38)(-$40) + (2/38)(-$40) = -$1.05

D. Doubling his bet does not increase Jeremy's odds of winning money, as his expected value is still negative.

The expected value for Jeremy's initial distribution is calculated by multiplying the net win for each event by its probability of occurring and summing the results. The expected value for Jeremy's new distribution is calculated in the same way, but with a net win of $40 instead of $20.

The negative expected value in both cases means that, on average, Jeremy can expect to lose money over time. Doubling his bet does not increase his odds of winning money, as his expected value is still negative. In fact, increasing his bet actually increases his expected loss per round, as seen in the comparison of the expected values for the two distributions.

This is due to the fact that the increased bet size does not change the underlying probabilities of the game. Roulette is a game of pure chance, and the odds of winning or losing a given round are always the same, regardless of the size of the bet.

In the question, the independence assumption may have been violated, while the Nearly Normal Condition is likely justified. Therefore, the use of the Student-t model for inference may be unreliable.

a) In order to perform a hypothesis test on the claim made by the diet guide, we need to assess the assumptions and conditions required for reliable inference. The independence assumption states that the observations are independent of each other. In this case, it is not explicitly mentioned whether the yogurt samples were independent or not. If the samples were obtained from the same batch or were not randomly selected, the independence assumption could be violated.

Regarding the Nearly Normal Condition, which assumes that the population of interest follows a nearly normal distribution, it is reasonable to assume that the distribution of calorie counts in vanilla yogurt is approximately normal. However, since we do not have information about the population distribution, we cannot definitively justify this condition.

b) The appropriate hypotheses for testing the claim made by the diet guide would be:

H0: The average calories per serving of vanilla yogurt is 120.

HA: The average calories per serving of vanilla yogurt is not equal to 120.

To test these hypotheses, we can use a t-test for a single sample. The test statistic (t) can be calculated by taking the mean of the sample calorie counts and subtracting the claimed average (120), divided by the standard deviation of the sample mean. The p-value can then be determined using the t-distribution and the degrees of freedom associated with the sample.

Without the actual sample mean and standard deviation, it is not possible to provide the specific test statistic and p-value for this scenario. These values need to be calculated using the given data (calorie counts) in order to draw a conclusion about the claim made by the diet guide.

Answer:

$2880

Step-by-step explanation:

First find the volume of the prism.

        l = 12 ft

        w = 8 ft

        h =10 ft

  \(\sf \boxed {\bf Volume \ of \ rectangular \ prism = l*w*h}\)

                                                        = 12 *8 * 10  

                                                        = 960 cubic feet

To find the rental cost, multiply the volume of the prism by the rental cost per cubic foot.

Rental cost = 960 * 3

                  = $ 2880

The radius of the circle is approximately 10.17 units (rounded to two decimal places).

To find the radius of the circle, we need to use the formula that relates the central angle to the length of the arc and the radius of the circle. The formula is given as:

arc length = radius x central angle

In this case, the arc length is given as 24.4 and the central angle is given as 2.4 radians. Substituting these values in the formula, we get:

24.4 = r x 2.4

Solving for r, we get:

r = 24.4 / 2.4

r ≈ 10.17

The rectangular coordinates of the point are (5, 0, 4e).

When working with points in three-dimensional space, it is often useful to describe them using different coordinate systems such as cylindrical, spherical, or rectangular.

In order to convert cylindrical coordinates to rectangular coordinates, we use a set of equations that relate the distance from the origin, the angle in the xy-plane, and the height to the corresponding x, y, and z values.

x = r*cos(theta)

y = r*sin(theta)

z = z

Where r is the radius, theta is the angle, and z is the height.

Given the cylindrical coordinates (5, , 4e), we can plug in the values into the equations to find the rectangular coordinates.

x = 5*cos() = 5*cos(0) = 5*1 = 5

y = 5*sin() = 5*sin(0) = 5*0 = 0

z = 4e

Therefore, the rectangular coordinates of the point are (5, 0, 4e).

To calculate the minimum sample size needed, we can use the formula: n = (z * σ / E)^2

Where:

z = the z-score associated with the desired level of confidence (let's assume 95% confidence, so z = 1.96)

σ = the standard deviation of the population (given in the problem statement)

E = the maximum error margin (given in the problem statement)

Plugging in the values, we get:

n = (1.96 * σ / E)^2

To determine the value of σ/E, we need more information. Let's assume that the maximum error margin E is 0.5, which means that the psychologist wants to be within 0.5 points of the true population mean si score.

Now, let's say that σ = 10 (just as an example). Then, σ/E = 10/0.5 = 20.

Plugging this into the formula, we get:

n = (1.96 * 10 / 0.5)^2 = 384.16

Rounding up to the nearest whole number, the minimum sample size needed is 385.

Therefore, the psychologist would need to take a random sample of at least 385 si scores from smokers to be confident that her estimate of the population mean si score is within 0.5 points.
