Alfred Wegener suggested that earth’s continents are moving. Which evidence supports this theory?

Answer:

Since this is means data and we do not know the populations standard deviation, a t-interval

needs to be used. The justification is found in checking the conditions needed for a t-interval. The

problem stated it was a random sample so we will assume this is sufficient. Since the sample size is

slightly under 30, we will still check for the data being roughly normal. Either a boxplot or normal

probability plot would suffice. In both cases there is no reason to doubt the sample data are roughly

normally distributed so we can proceed to the calculations.

The interval would be (69, 76)

Answer:

b/a

Explanation:

ax + by = c

In order to find the slope put the equation in slope-intercept form (y=mx+b):

Solve for y:

ax + by = c

by = c - ax  ==> subtract ax on both sides

y = (c - ax) / b  ==> divide both sides by b to isolate y

y = c/b - ax/b  ==> distribution property

y = -ax/b + c/b  ==> turn the equation into y=mx+b format

-ax/b  ==> The slope is -a/b

Now that we found the slope of the original line, we need to find the slope of the line perpendicular to it.

Perpendicular lines have slopes that are opposite reciprocals:

An example of opposite reciprocals are -1/2 and 2:

Negate 2 to get -2

-2 = -2/1  ==> any number that is divided by 1 is itself

The reciprocal of -2/1 is -1/2

Hence, the opposite reciprocal of 2 is -1/2

Now apply this concept to the slope -a/b:

Negate -a/b to get -(-a/b) = a/b

The reciprocal of a/b is b/a

Hence, the slope of the perpendicular line is b/a.

To find the slope of a line that is perpendicular to a given line, we can use the negative reciprocal of the slope of the given line.

The slope of a line in the form of ax + by = c is the coefficient of x (a) divided by the coefficient of y (b). In this case, the slope of the line is -a/b.

A line perpendicular to the line ax + by = c will have a slope that is the negative reciprocal of -a/b. So the slope of a line perpendicular to the line ax + by = c is b/a.

Note that when a = 0 or b = 0, the slope is undefined. In this case, the line is a vertical or horizontal line respectively and its perpendicular line is the other type of line.

Therefore, the slope of a line perpendicular to the line ax + by = c is b/a, as long as a is not equal to zero.

Answer:

z = 1.00

Explanation:

Given:

Probability of z value  = 0.6826

By using standard normal table for z value.

P(-z < Z < z) = 0.6826

P(Z < z) - P(Z < -z) = 0.6826

We know that

P(Z < z) + P(Z < -z) = 1

So,

2P(Z < z) - 1 = 0.6826

2P(Z < z) = 1 + 0.6826

2P(Z < z) = 1.6826

P(Z < z) = 1.6826 / 2

P(Z < z) = 0.8413  

So,

P(Z < 1.00) = 0.8413  

z = 1.00

Answer:

C

Explanation:

A star does not necessarily get brighter or dimmer when you get closer to it. The apparent brightness of a star is determined by both its intrinsic luminosity (how much energy it emits) and its distance from Earth. If you move closer to a star, the distance between you and the star decreases, so the apparent size of the star increases. However, if the intrinsic luminosity remains the same, the net effect on brightness will be negligible. On the other hand, some stars may appear to change in brightness due to atmospheric effects, such as scintillation and atmospheric extinction, which can affect the amount of light that reaches Earth and how it is perceived.

Within 10 to 20 minutes after a drink is consumed, all of the alcoholic content has probably been absorbed into the body.

Approximately 20% of alcohol exists absorbed through the stomach and most of the remaining 80% exists absorbed through the small intestine. Alcohol exists metabolized by the liver, where enzymes split down the alcohol.

Within 10 to 20 minutes after a drink is consumed, all of the alcoholic content has probably been absorbed into the body.

It takes 30 minutes to feel the effects of alcohol. It may take an hour to metabolize a drink, but it takes approximately thirty minutes before you feel alcohol's effects. This is a good gauge for pacing yourself.

Answer:

The mean of the distribution is 4.00 and the standard deviation is 2.31

Explanation:

Given

Range = 2 to 10

Type of distribution = uniform distribution

Required

1. Mean

2. Standard Deviation

The mean of uniform distribution is calculated as thus;

\(Mean = \frac{1}{2}(a + b)\)

Where b and a are the intervals of the distribution

b = upper bound = 10

a = lower bound = 2

So,

\(Mean = \frac{1}{2}(a + b)\)

Substitute 10 for b and 2 for a

\(Mean = \frac{1}{2}(2 + 10)\)

\(Mean = \frac{1}{2}(12)\)

\(Mean = \frac{1}{2} * 12\)

\(Mean = 6\)

\(Mean = 6.00\) (Approximated to 2 decimal places)

The standard deviation of uniform distribution is calculated as thus;

σ = √σ²

Where σ represents the standard deviation and σ² represents the variance.

Calculate variance

σ² = Var

\(Var = \frac{(b-a)^2}{12}\)

Substitute 10 for b and 2 for a

\(Var = \frac{(10 - 2)^2}{12}\)

\(Var = \frac{8^2}{12}\)

\(Var = \frac{64}{12}\)

\(Var = 5.33\)

Recall that

σ = √σ² = √Var

Substitute 5.33 for Var

σ = √5.33

σ = 2.309401076758503

σ = 2.31 (Approximated)

Hence, the mean of the distribution is 4.00 and the standard deviation is 2.31

Without understanding the exact content, context or scope of the dictionary that you're talking about, it is challenging to determine the exact position of the word "buccaneer." However, using simple logic, as per the alphabetical order, the word "buccaneer" can likely be positioned between the words based on the order of their starting alphabets.

For example, if the words "bubble" and "bucket" are already present in that particular dictionary, the word "buccaneer" can be placed between them, and it would follow "bubble" and precede "bucket".

The precise positioning of "buccaneer" would rely on the words that are already there in the dictionary and the sorting rules used by the publisher which can include (and not be limited to)- the consideration of spaces, special characters, capitalization, etc.

Answer:

The large airline company, Cloudscape, knows from experience that only 72% of the passengers booked for flights actually show up. Suppose that we will take a random sample of 7 Cloudscape passengers. Let p represent the proportion of passengers from the sample who show up for their flight. Consider the sampling distribution of the sample ...

Explanation:

The sample proportion based on the question that we have here is 0.72

The sample proportion (p) indicates the percentage of people in a sample who exhibit a particular quality or attribute. Divide the number of individuals (or items) who have the desired attribute by the overall sample size to obtain the sample proportion.

P=X/N, where X represents the number of successes and N represents the sample size, yields the sample proportion.

Hence from the question, we see that 72% of the passengers booked for flights actually show up.  hence the proportion is 0.72.
