What is the value of x? (Simply your answer)

Answer:

15=x  5x=75

Step-by-step explanation:

90/6=15

6 is how many x's there are in total meaning that 1 x = 15

15*5=75 so one angle is 15 while the other is 75

75 + 15= 90

90+90=180 getting you the 180 degrees

The least-squares regression line of height versus age will have a slope of 0.8 .  Was true statement option (2)

The correlation coefficient (r) measures the strength and direction of a linear relationship between two variables, in this case, height and age. A correlation coefficient of 0.8 indicates a strong positive linear relationship between height and age. The slope of the least-squares regression line represents the change in the height of a child for each one-unit increase in age.

Therefore, a slope of 0.8 indicates that for each one-year increase in age, the expected increase in height is 0.8 units. The other options are not correct or relevant based on the given information.

The standard deviation is decreases then the graph of the normal z - score curve is increases.

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

The standard deviation is calculated as the square root of variance by determining each data point's deviation relative to the mean. If the data points are further from the mean, there is a higher deviation within the data set; thus, the more spread out the data, the higher the standard deviation.

In mathematics, the Z score is used to quantify how many standard deviations the raw score deviates from or approaches the mean. Giving the z score are:

z = (x - μ ) / σ

Where,

x = raw score

μ = mean

σ = standard deviation

For a sample size,

z =  (x - μ ) / σ / \(\sqrt{n}\)

The z score affects the area under the curve. The area under the curve increases as the z score increases and decreases as the z score decreases.

The standard deviation has an inverse relationship with the area under the curve (z score). The z score drops as the standard deviation rises, diminishing the area under the curve.

The area under the curve grows as the standard deviation is reduced because the z score increases.

Therefore,

The standard deviation is decreases then the graph of the normal z - score curve is increases.

Cora is flipping three coins at once. The probability that the number of landed coins showing "heads" is less than 3 is 0.875

Probability is a measure how likely an event occurs. Probability of an event A is calculated as:

P(A) = number of ways A can occur / total possible outcomes

Let A and B be independent events, then the followings hold:

P (A and B) = P (A∩B) = P(A) + P(B)

P (A or B) = P (A∪B) = P(A) · P(B)

P (not A) = P(Ā) = 1 - P(A)

In the given problem, H is an event where the number of landed coins showing heads.

The probability distribution for H is:

P(H = 0) = 0.125

P(H = 1) = 0.375

P(H = 2) = 0.375

P(H = 3) = 0.125

The probability of three coins show heads less than 3 is:

P(H < 3) = 1 - P(H=3)

             = 1 - 0.125 = 0.875

It can also be obtained using:

P(H<3) = P(H=0) + P(H=1) + P(H=2)

           = 0.125 + 0.375 + 0.375

           = 0.875

Hence, the probability of three coins show heads less than 3 is 0.875.

Complete question:

Cora is playing a game that involves flipping three coins at once. Let the random variable H be the number of coins that land showing "heads". Here is the probability distribution for H:

Each of Maddy's friend will get 66 apples, with 5 remaining apples left over.

Maddy has 1655 apples and she wants to distribute them equally among her 25 friends. To find out how many apples each friend will receive, we divide the total number of apples by the number of friends.

1655 apples ÷ 25 friends = 66.2 apples per friend.

Since we can't have a fraction of an apple, we need to round the number to a whole number.

Considering that we want to distribute the apples equally, each friend will receive approximately 66 apples.

If we distribute 66 apples to each of the 25 friends, the total number of apples distributed will be 66 * 25 = 1650. There will be 5 apples remaining, which cannot be evenly distributed among the friends.

The statement is true.

The average length of time between successive events of a given size (or larger) is indeed referred to as the recurrence interval (RI).

To understand this concept better, let's break it down:

1. Recurrence Interval (RI): The recurrence interval is a measure used in statistics and probability to determine the average time between events of a specific size or larger.

It is commonly used in fields such as hydrology, seismology, and finance to analyze the frequency and magnitude of events.

2. Successive Events: In this context, successive events refer to events that occur one after the other, without any gaps in between.

For example, if we are studying earthquakes, successive events would be the occurrence of earthquakes of a certain magnitude within a specific area.

3. Given Size or Larger: The recurrence interval focuses on events of a given size or larger. This means that we are considering events that meet or exceed a particular threshold.

For instance, if we are analyzing rainfall patterns, we might be interested in the recurrence interval of rainfall events that exceed a certain amount, such as 1 inch or more.

To illustrate this concept, let's consider an example:

Suppose we are studying hurricanes in a coastal region. We want to determine the average length of time between Category 3 or higher hurricanes.

We collect data and find that, on average, there is a Category 3 or higher hurricane every 5 years.

In this case, the recurrence interval (RI) for Category 3 or higher hurricanes would be 5 years. This means that, on average, we can expect a Category 3 or higher hurricane to occur once every 5 years in that coastal region.

To summarize, the statement is true: the average length of time between successive events of a given size (or larger) is referred to as the recurrence interval (RI).

It helps us understand the frequency and timing of specific events in various fields of study.

When the production manager selects a sample of items that have been produced on her production line and computes the proportion of those items that are defective, the proportion is referred to as a statistic.

The statement is true.

A statistic can be the sample mean or the sample standard deviation, which is a number computed from sample. Since a sample is random in nature therefore every statistic is a random variable (that is, it differs from sample to sample in such a way that it cannot be predicted with certainty).

Statistics are computed to estimate the corresponding population parameters.

Here the production manager selects a sample of items produced on her production line to compute the proportion of defective items, that is taken from the sample and would later be used to represent the entire bunch of items produced. Thus, the proportion can be referred to as a statistic.

The graph of g(x) is obtained by transformations of functions translating the graph of f(x) downward by 3 units, and the point (0, -3) is on the graph of g(x).

To transform the graph of f(x) = 3x to represent the function g(x) = 3x - 3, we need to perform a translation.

To translate the graph of f(x), we shift it vertically downward by 3 units. This means that each point on the graph of f(x) will be moved downward by 3 units to obtain the corresponding point on the graph of g(x).

The point (0, 0) on the graph of f(x) will be translated to (0, -3) on the graph of g(x), as it moves down by 3 units.

Therefore, the graph of g(x) is obtained by transformations of functions translating the graph of f(x) downward by 3 units, and the point (0, -3) is on the graph of g(x).
