The probability of the random item chosen that it is less than 16.4 inches long is 2.7%

Probability means ?

The likelihood of an event happening is calculated using the probability formula. To review, probability is the probability that an event will occur. What is the likelihood that a specific event will occur when a random experiment is considered? is one of the first queries that pops into our heads. A prediction's chance is expressed as a probability. If we suppose that, for example, x represents the probability that an event will occur, then (1-x) is the probability that the event will not occur.

4p - 2=7.16 is a formula that can be used to determine the standard price of a pair of socks.

Step-by-step explanation:

The information that we know is...

- Michael purchased four pairs of socks.

-  After utilizing a $2 off coupon, he spent $7.16.

We're expected to figure out what formula we should apply to get the standard price of a pair of socks so...

We start by writing 4p.

4 represents a pair of socks, and p represents the normal price of socks.

4p - 2

Then subtract 2 since he utilized a $2 off coupon.

4p - 2 = 7.16

Lastly, add = 7.16 because he paid in total $7.16.

So, 4p - 2=7.16 is a formula that can be used to determine the standard price of a pair of socks.

The value 34 is at the 55th percentile in the given dataset, meaning it is higher than 55% of the values and lower than 45% of the values.


To determine the percentile of 34 in the given dataset, we first need to arrange the values in ascending order: 1 1 1 1 1 1 2 3 5 8 13 21 34 55 89 89 89 89 89 89.
The percentile of a value represents the percentage of values in a dataset that are equal to or less than that value. In this case, there are 12 values that are less than or equal to 34. The total number of values in the dataset is 20.

To calculate the percentile, we use the formula:
Percentile = (Number of values less than or equal to the given value / Total number of values) × 100.
Therefore, the percentile of 34 is (12/20) × 100 = 60%. This means that 34 is higher than 60% of the values and lower than 40% of the values in the dataset.

Answer:

approximately normal with mean=4.2 and standard deviation=0.3.

The sampling distribution of the sample mean is a normal distribution with a mean equal to the population mean and a standard deviation equal to the population standard deviation divided by the square root of the sample size. In this case, since the population mean is 4.2 cars and the population standard deviation is 3 cars, and we have a sample size of 100 days, then the sampling distribution of the sample mean will have a mean of 4.2 cars and a standard deviation of 3/sqrt(100) = 0.3 cars.

Step-by-step explanation:

The sampling distribution of the sample mean is the distribution of the mean of a sample of observations from a population. In this case, the sampling distribution of the sample mean would be a normal distribution with a mean of 4.2 and a standard deviation of 33/sqrt(100) = 1.6. This means that 68% of the time, the sample mean would be between 2.6 and 5.8, and 95% of the time, the sample mean would be between 1.6 and 7.8.

The sampling distribution of the sample mean is important because it can be used to make inferences about the population mean. For example, if the sample mean is 5.8, we can be 95% confident that the population mean is between 1.6 and 7.8.

The question asks you to analyze a statistical model used to estimate earnings based on various factors. You will need to interpret the significance of variables, coefficient estimates, and the overall fit of the model.

1. Without seeing the variables included in the earning equation, it is impossible to determine which variables are significant. However, the reported standard errors can be used to test the significance of each coefficient. If the absolute value of a coefficient divided by its standard error is greater than 1.96, then the variable is considered significant at the 5% level.

2. The coefficient estimate on females cannot be interpreted without seeing the entire equation.

3. R2 represents the proportion of variation in the dependent variable (in this case, earnings) that can be explained by the independent variables included in the equation. An R2 of 0.17 indicates that the included variables can explain 17% of the variation in earnings.

Answer:

y = 4

Step-by-step explanation:

8(y + 4) - 2(y - 1) = 70 - 3y ← distribute parenthesis and simplify left side

8y + 32 - 2y + 2 = 70 - 3y

6y + 34 = 70 - 3y ( add 3y to both sides )

9y + 34 = 70 ( subtract 34 from both sides )

9y = 36 ( divide both sides by 9 )

y = 4

As we have proved that the line created works exclusively with the three points by justifying how the x-value and y-value fit into the equation for the line.

Let's start by defining what a linear function is. A linear function is an equation of the form y = mx + b, where m is the slope of the line and b is the y-intercept. The slope represents the rate of change of the line, and the y-intercept represents the value of y when x is equal to zero. To create a linear function, we need two points on the line.

Now, let's create another linear function using points B and C:

slope (m) = (y₂ - y₁) / (x₂ - x₁) = (6 - 4) / (5 - 3) = 1

y-intercept (b) = y - mx = 4 - 1 * 3 = 1

Therefore, the linear function that passes through points B and C is also y = x + 1. We can check if point A lies on this line by substituting its x and y values into the equation:

2 = 1 + 1

This is true, so point A lies on the line created by points B and C. Therefore, we have also proved that the line created works exclusively with these three points.

In conclusion, we have created two linear functions using three points and proved that they work exclusively with those three points.

The point Q is (-2, 5), which corresponds to option A.

To find the point Q that partitions the line segment PR into segments PQ and QR in the ratio 4:5, we need to use the ratio formula:
Q = (5P + 4R) / 9
where Q is the coordinates of the point we're looking for, P is the coordinates of the starting point of the line segment PR (in this case P(-10,7)), R is the coordinates of the ending point of the line segment PR (in this case R(8,-5)), and 9 is the sum of the ratio values (4+5=9).
To find point Q that partitions line segment PR in the ratio 4:5, we can use the section formula:
Q(x, y) = ((m1 * x2 + m2 * x1) / (m1 + m2), (m1 * y2 + m2 * y1) / (m1 + m2))
where P(x1, y1) = (-10, 7), R(x2, y2) = (8, -5), and the ratio is 4:5 (m1 = 4, m2 = 5).
Q(x, y) = ((4 * 8 + 5 * -10) / (4 + 5), (4 * -5 + 5 * 7) / (4 + 5))
Q(x, y) = ((32 - 50) / 9, (-20 + 35) / 9)
Q(x, y) = (-18 / 9, 15 / 9)
Q(x, y) = (-2, 5)

Therefore, the point Q on the line segment PR that partitions it into the segments PQ and QR in the ratio 4:5 is option A, (-2, 5).

Because the graph always has a consistent slope of +2, the table x|y-2| 4|0| 6|2| is an illustration of a linear function table.

In order for a table to represent a linear function, there must be a constant rate of change (slope) between any two points on the graph. In other words, the relationship between the x-values and y-values should follow a consistent pattern.

The correct table that represents a linear function is: x|y-2| 4|0| 6|2|This is because there is a constant rate of change of +2 between any two points on the graph. For example, when x goes from 2 to 4, y increases from -2 to 0. When x goes from 4 to 6, y increases from 0 to 2.

This constant rate of change indicates that the relationship between x and y is linear.

In summary, a table represents a linear function when there is a constant rate of change between any two points on the graph. The table x|y-2| 4|0| 6|2| is an example of a linear function table because there is a consistent slope of +2 between any two points on the graph.

Step-by-step explanation:

The Miller index notation for the (100) plane in an FCC crystal structure is [100].

Miller indices are a way to describe crystal planes and directions in a standardized manner. In the case of FCC crystal structure, the (100) plane is parallel to the x-y plane and intersects the x-axis, y-axis, and z-axis at points where the Miller indices are (1,0,0), (0,1,0), and (0,0,1), respectively.

However, to express the (100) plane in a concise and standardized manner, we can use the Miller index notation, which involves taking the reciprocals of the intercepts of the plane with the crystallographic axes and then reducing them to the smallest integer values. In the case of the (100) plane in FCC, all of the intercepts are 1, so the Miller indices are [100].

the pd expression for the (100) plane in FCC crystal structure is [100].

The recurrence relation that describes the sequence {g} is option (b) = (1.1)⋅−1.


The problem states that the population of mice increases by 10% every year. This means that if we start with a population of 100 mice, after one year the population will be 110 (100 + 10% of 100). After two years, the population will be 121 (110 + 10% of 110), and so on.

Let's use the variable g to represent the population of mice after n years. Then, we can write:

g = 1.1g_{n-1}

This recurrence relation says that the population after n years is equal to 1.1 times the population after n-1 years. This makes sense because the population increases by 10% every year.

To find the population after a specific number of years, we can use the recurrence relation repeatedly. For example, to find the population after 3 years, we can write:

g_3 = 1.1g_2
g_2 = 1.1g_1
g_1 = 1.1g_0

If we start with a population of 100 mice (g_0 = 100), then we can find the population after 3 years as follows:

g_1 = 1.1g_0 = 1.1(100) = 110
g_2 = 1.1g_1 = 1.1(110) = 121
g_3 = 1.1g_2 = 1.1(121) = 133.1

So after 3 years, the population of mice would be approximately 133.



the recurrence relation that describes the sequence {g} is (b) = (1.1)⋅−1. This means that the population of mice after n years is equal to 1.1 times the population after n-1 years. To find the population after a specific number of years, we can use the recurrence relation repeatedly.
