Step-by-step explanation:

The estimated mean volume of the diet cola cans is between 11.97 and 12.05 ounces with 95% confidence for the particular hour.

This means that if the supervisor were to repeat this process many times, in 95% of the cases, the true mean volume of the diet cola cans would fall within the interval of 11.97 to 12.05 ounces.

The sample size of 10 cans selected at random is sufficient for this confidence interval to be accurate. This information can be used by the company to ensure that their cans are consistently filled to the advertised volume, and by consumers to have confidence in the volume of the product they are purchasing.

Answer: 771 3/8

Step-by-step explanation:

15 3/8+756

we can apply the assosiative propery and do 15+756+3/8

so 15+756= 771

so finally you do 771+3/8=771 3/8

In a circle, when two diameters intersect, the angles formed at the intersection point are always right angles (90°).

Therefore, none of the given angle measures (50°, 80°, 100°, 130°) can represent the angle formed by diameters AC and BD.

The correct answer would be 90° since the intersection of diameters always creates right angles in a circle.

Among the given options, the reason that has not been cited for the future growth of remote patient monitoring is the decline of rural hospitals (option D).

Remote patient monitoring is expected to experience future growth due to several factors. Firstly, chronic conditions among the elderly (option A) play a significant role in the demand for remote patient monitoring. With an aging population (option B), there is an increasing need for healthcare services that can be provided remotely to accommodate the growing number of individuals requiring care.

Additionally, the reduction in the cost of technology (option C) has made remote patient monitoring more accessible and affordable, thereby driving its adoption.

However, the decline of rural hospitals (option D) is not commonly cited as a reason for the future growth of remote patient monitoring. While the availability of healthcare services in rural areas may be a concern, the growth of remote patient monitoring is typically associated with its ability to provide remote care to patients regardless of their geographical location. Remote patient monitoring allows individuals in rural areas to access healthcare services without the need for physical proximity to healthcare facilities.

The mean is the measure of the central tendency most likely to be affected by an outlier.

The following statement is correct.

The term "mean" is another synonym for "average." When there is an outlier in the data set, the mean suffers the most. The only measure of central tendency on which an outlier will always have an effect is the mean.

The mean is the only measure of central tendency that is affected by all values since it is calculated by dividing the total of the values by the number of observations.

The arithmetic mean is the average quantity in a given set of data. It is defined as the sum of all observations in the data divided by the total number of observations in the data. As a result, because it comprises all of the data in a series, the mean is influenced by the extreme values.

Answer:

\(y = \dfrac{1}{4} x - 4\)

Step-by-step explanation:

Slope intercept form of line equation is y = mx + b, m = slope, b = y-intercept

Slope of line perpendicular to y =m x + b will have slope   - (1/m)

4x+y=3 can be re-written as
y = -4x + 3

Slope = -4

Slope of line perpendicular to this line is - (1/-4)  = 1/4

Line equation: y = (1/4) x + b

Plug in x, y values from given point into this line equation to find b
-3 = 1/4 x 4 + b

-3 = 1 + b

-3 -1 = b

b = -4

So equation of perpendicular line is y = (1/4)x - 4

A) The expected value of X is 3.93.

B) The probability of at most two successes in six independent Bernoulli trials with p = 0.4 is 0.626.

C) The standard deviation of X is 0.89.

A. The expected value of a random variable is the sum of the products of each possible outcome and its probability. In the given probability distribution, we have four possible outcomes: 2, 4, 6, and 8, with respective probabilities of 5/58, 20/58, 13/58, and 20/58. We can calculate the expected value of X using the formula:

E(X) = Σ(xi * P(X = xi)), where xi represents each possible outcome.

Therefore, E(X) = (2 * 5/58) + (4 * 20/58) + (6 * 13/58) + (8 * 20/58) = 3.93

B. In Bernoulli trials, we have two possible outcomes, success or failure, with respective probabilities of p and q = 1 - p. The probability of at most two successes in six independent Bernoulli trials with p = 0.4 can be calculated using the binomial distribution formula:

P(X ≤ 2) = Σ(i=0 to 2) (6Ci * 0.4i * 0.6(6-i)), where Ci represents the combination of selecting i items from a set of six.

Therefore, P(X ≤ 2) = (6C0 * 0.40 * 0.62) + (6C1 * 0.41 * 0.61) + (6C2 * 0.42 * 0.60) = 0.626

C. The standard deviation of a probability distribution is a measure of how much the outcomes deviate from the expected value. It is calculated using the formula:

σ = √(Σ(xi - μ)2 * P(X = xi)), where μ represents the expected value.

In the given probability distribution, we have four possible outcomes with respective probabilities and deviations from the expected value:

xi 0 1 2 3

P(X=xi) 0.1 0.1 0.6 0.2

(xi - μ)2 3.24 1.44 0.04 1.44

Using the above values, we can calculate the standard deviation of X as follows:

σ = √((3.24 * 0.1) + (1.44 * 0.1) + (0.04 * 0.6) + (1.44 * 0.2)) = 0.89

In a triangle, we have three angles and three sides. The Law of Sines says that for any triangle, the ratio between the sine of an angle and the length of the opposite side will be the same for all three angles. In other words, the sine values of each angle are proportional to the length of the opposite side.

To put this in mathematical terms, let's consider a triangle with angles A, B, and C, and sides a, b, and c respectively. The Law of Sines can be written as:

sin(A)/a = sin(B)/b = sin(C)/c

This means that if we know the length of any two sides and the measure of the angle opposite one of those sides, we can use the Law of Sines to find the measure of the other angles and sides.

Given,

Probability;-

Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.

Here,

The number of fortunate situations divided by the total number of coins would be the product between the probability of each occurrence and the likelihood of each event.

Therefore,

P(nickel) = 19/69

P(penny) = 17/68

Step-by-step explanation:

The sum of all three angles; <ABC, <ABD, and <CBD is equal to 360

now we know <ABC = 118 and

the measure of central angle <CBD is equal to measure of the arc it sees so it's = 105

we are asked to find the  m<ABD

118 + 105 + <ABD = 360 add like terms

223 + <ABD = 360 subtract 223 from both sides

m<ABD = 137

Answer:  r and b are both positive or both negative

Reason:

The correlation coefficient r is between -1 and 1

\(-1 \le r \le 1\)

If r = -1, then we have perfect negative correlation. All points are on the same straight line that goes downhill as you move to the right. This slope is negative. If -1 < r < 0, then we still have negative slope but the points aren't all on the same line.

If r = 1, then the slope is positive. The regression line moves upward as you move to the right. All points are on this line. If 0 < r < 1, then the points aren't on the same line but we have a positive slope.

If r = 0, then we have no linear correlation at all. Either the points are randomly scattered or they fall on a curve (eg: parabola).
