To find the probability that the sample mean is greater than 0.45 but less than 0.650

we can use the formula below.z = (x - μ) / (σ / √n)Where z is the standard normal distribution value, x is the sample mean, μ is the population mean, σ is the population standard deviation, and n is the sample size.

Using this formula, we can standardize the sample mean and find the corresponding probability from the standard normal distribution table. For this problem, we are given that the sample mean falls between 0.45 and 0.65. Let's call this range X, where X = (0.45, 0.65). Then, we can write the main answer as  P(0.45 < x < 0.65) = P((0.45 - μ) / (σ / √n) < z < (0.65 - μ) / (σ / √n))To find this probability, we need to know the population mean and standard deviation. If these are not given in the problem, we cannot find the exact probability.

However, we can make some conclusions based on certain assumptions. For example, if we assume that the population is normally distributed, we can use the central limit theorem to approximate the sample mean distribution as normal. Then, we can use the sample mean and sample standard deviation to estimate the population mean and standard deviation, respectively. From there, we can use the standard normal distribution table to find the corresponding probabilities. Therefore, without more information about the population distribution and parameters, we cannot find the exact probability that the sample mean is greater than 0.45 but less than 0.65. However, we can conclude that this probability will be between 0 and 1.

The formula 2x/(x-7) - (x+7)/x therefore equals (x² + 49) / (x × (x-7)).

Mathematical expressions consist of at least two integers or factors, a minimum of one math procedure, and a sentence. It's possible to multiply, divide, add, or remove with this mathematical procedure.

To simplify the expression 2x/(x-7) - (x+7)/x, we need to find a common denominator.

First, we can rewrite the second term as (x+7)/(x × 1), so the expression becomes:

2x/(x-7) - (x+7)/(x × 1)

To find a common denominator, we need to multiply the first term by x/x and the second term by (x-7)/(x-7):

2x × x / (x × (x-7)) - (x+7) × (x-7) / (x × (x-7))

Simplifying the expression further, we get:

(2x² - (x² - 49)) / (x × (x-7))

Simplifying the numerator, we get:

(2x² - x² + 49) / (x × (x-7))

And finally, we can simplify the expression to:

(x² + 49) / (x × (x-7))

Therefore, the expression 2x/(x-7) - (x+7)/x is equivalent to (x² + 49) / (x × (x-7)).

Answer:

22.5 glasses of water

Step-by-step explanation:

Because 3/4 of 10 is 7.5 and if he drinks that every 2 min you have to multiple 7.5 by 30 because 60/2 is 30 which is the amount of min in an hour. when you multiple, you get 225. you have to divide that many oz by 10 because that is how many oz are in a glass and you get 22.5 glasses.

Yes, because every x-value corresponds to exactly one y-value.

==================================================

Further explanation:

If the table had two points such as (10,1250) and (10,1300), then it would lead to "not a function" because x = 10 corresponds to more than one y value.

Instead, each x input leads to exactly one y output. Therefore, we have a function. You can use the vertical line test to confirm visually.

-----------

In short,

The y values can repeat, but the function wouldn't be one-to-one (aka injective). In this case, the y values do not repeat so this function is one-to-one.

The volume of the solid can be found by integrating the expression V = ∫(2πx)(2e^(5x))dx from x = -1 to x = 2. Evaluating this integral will give us the volume of the solid.

To find the volume of the solid generated by revolving the region bounded by the given equations about the x-axis, we can use the method of cylindrical shells.

By integrating the appropriate formula, we can calculate the volume of the solid.

The region bounded by the graphs of the equations y = e^(5x) + e^(-5x), y = 0, x = -1, and x = 2 is a finite region between the x-axis and the curve. When this region is revolved about the x-axis, it creates a solid with a cylindrical shape. To find its volume, we integrate the formula for the volume of a cylindrical shell over the appropriate range.

The volume V can be calculated as V = ∫(2πx)(y)dx, where y represents the height of the cylindrical shell at each x-value. By evaluating this integral with the given equations and limits, we can find the volume of the solid.

To solve the problem, we first need to express the equation y = e^(5x) + e^(-5x) in terms of x. Notice that the equation is symmetric, so we can rewrite it as y = 2e^(5x). The region bounded by the curves y = 0, x = -1, and x = 2 will have a height of 2e^(5x) and a width of dx.

Therefore, the volume of the solid can be found by integrating the expression V = ∫(2πx)(2e^(5x))dx from x = -1 to x = 2. Evaluating this integral will give us the volume of the solid.

If the sample size (n) is greater than 30 or if the original population is normally distributed, then the central limit theorem (CLT) can be applied. The CLT states that the sampling distribution of the sample mean will be approximately normal, regardless of the shape of the original population distribution, as long as the sample size is sufficiently large.

The sampling distribution of the sample mean refers to the distribution of all possible sample means that could be obtained from repeated sampling from the same population. The shape of the sampling distribution of the sample mean depends on the sample size and the shape of the original population distribution.

When the sample size is greater than 30, the standard error of the sample mean decreases and the distribution of sample means becomes more concentrated around the population mean. This allows the sampling distribution of the sample mean to approximate a normal distribution, even if the original population distribution is not normal.

Similarly, if the original population is normally distributed, then the sampling distribution of the sample mean will also be normal regardless of the sample size. This is because the normal distribution is preserved through the process of taking means from random samples.

In summary, when the sample size is greater than 30 or the original population is normally distributed, the sampling distribution of the sample mean will be approximately normal. This property is important in statistical inference, as it allows us to use the normal distribution to make inferences about population parameters based on sample statistics.

So the order from left to right would be: Mode, Median, Mean.

In a positively skewed distribution, the mean is typically larger than the median, and the median is larger than the mode.

This can be illustrated in the following way:

Mean: The mean is affected by extreme values in the tail of the distribution, and will be pulled in the direction of the skew. Therefore, in a positively skewed distribution, the mean will be to the right of the median.

Median: The median is the value that separates the lower 50% of the data from the upper 50% of the data. In a positively skewed distribution, the tail of the distribution is on the right-hand side, which means that the median will be closer to the left-hand side than the mean.

Mode: The mode is the most frequent value in the distribution. In a positively skewed distribution, the mode will be the smallest value, located at the left-hand side of the distribution, while the mean and median will be to the right of it.

the rate of change of the radius at the instant the volume equals 36π cm³ is 7 / (36π) cm/sec.

The volume V of a sphere with radius r is given by the formula V = (4/3)πr³. We are given that the rate of change of the volume is 7 cm³/sec. Differentiating the volume formula with respect to time, we get dV/dt =(4/3)π(3r²)(dr/dt), where dr/dt represents the rate of change of the radius with respect to time.

We are looking for the rate of change of the radius, dr/dt, when the volume equals 36π cm³. Substituting the values into the equation, we have: 7 = (4/3)π(3r²)(dr/dt)

7 = 4πr²(dr/dt) To find dr/dt, we rearrange the equation: (dr/dt) = 7 / (4πr²) Now, we can substitute the volume V = 36π cm³ and solve for the radius r: 36π = (4/3)πr³

36 = (4/3)r³

27 = r³

r = 3  Substituting r = 3 into the equation for dr/dt, we get: (dr/dt) = 7 / (4π(3)²)

(dr/dt) = 7 / (4π(9))

(dr/dt) = 7 / (36π)

The concept of consecutive integers is explained as follows:

Consecutive numbers, or consecutive integers, are integers that follow each other in order. The difference between any two consecutive numbers is always 1. For example, the consecutive numbers starting from 1 would be 1, 2, 3, 4, 5, and so on. Similarly, the consecutive numbers starting from -3 would be -3, -2, -1, 0, 1, 2, and so on.

It is important to note that if we have a consecutive sequence of integers, one number will be even, and the next number will be odd. This is because the parity (evenness or oddness) alternates as we move through consecutive integers.

Furthermore, the sum of two consecutive numbers (and, in fact, the sum of any number of consecutive numbers) is always an odd number. This is because when we add an even number to an odd number, the result is always an odd number.

To generate a sequence of consecutive integers, we can start with any integer n and then use n, n+1, n+2, and so on to obtain consecutive integers. For example, if n is an integer, then n, n+1, and n+2 will be consecutive integers.

Here are some examples of consecutive integers:

- Starting from 1: 1, 2, 3, 4, 5, ...

- Starting from -3: -3, -2, -1, 0, 1, 2, ...

- Starting from 1004: 1004, 1005, 1006, 1007, ...

Answer:

8/9

Step-by-step explanation:

Step 1: Convert both 4 1/3 and 3 4/9 to improper fractions:

Converting 4 1/3 to an improper fraction:

For 4 1/3, we'll mutiply 4 by 3, add 1 to that, and keep 3 as the denominator:

((4 * 3) + 1) / 3

((12 + 1) / 3

13/3

Thus, 4 1/3 as an improper fraction is 13/3.

Converting 3 4/9 to an improper fraction:

For 3 4/9, we'll multiply 3 by 9, add 4 to that, and keep 9 as the denominator:

((3 * 9) + 4) / 9

(27 + 4) / 9

31/9

Thus, 3 4/9 as an improper fraction is 31/9.

Finding the difference of 13/3 and 31/9:

(13/3) * (3/3) = 39/9

Now, we simply subtract 31/9 from 39/9:

39/9 - 31/9

8/9

Thus, 4 1/3 - 3 4/9 = 8/9.
