the quantity p(x = 1) is equal to

Number of seconds it takes the object to travel the entire length of the path is 15 seconds.

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

Given that, the object travels 1/20 of the length of the path in 3/4 seconds.

1/20 is a tiny portion of the length that needs to be traveled.  

20/20 is the whole length.  

If 1/20 gets traveled in 3/4 of a second, multiply 3/4 by 20.

That is, 20(3/4) = 15 seconds

Therefore, number of seconds it takes the object to travel the entire length of the path is 15 seconds.

The mass in grams of 0. 450 moles of magnesium sulfate, MgSO4 in grams is 54.2.

The mole, which is 6.0221023 molecular entities, is the basic unit of a substance. One mole of a substance is equivalent to that substance's molecular weight.

The link between moles and molar mass means that the quantity of moles in a material is equal to the product of its mass and molecular mass.

The molar mass of magnesium sulphate is:

Magnesium = 24

Oxygen = 16 x 4 = 64

Sulphate = 32

Thus, the mass of magnesium sulphate is = 24 + 64 + 32 = 120 grams.

Now, moles is equal to:

Moles = given mass/molecular mass

Putting the values:

moles = given mass / 120

0.450 x 120 = given mass

Given mass = 54g.

Thus, the given mass of the magnesium sulphate is 54 g.

The probability that the sample mean is between 39.75 and 41.25 is approximately 0.5987.

The probability that the sample mean is between 39.75 and 41.25 can be calculated using the Central Limit Theorem. This theorem states that the distribution of the sample means will be normally distributed with a mean equal to the population mean (μ = 40) and a standard deviation equal to the population standard deviation divided by the square root of the sample size (σ = 8/√32).

Using this information, we can calculate the probability that the sample mean is between 39.75 and 41.25, which will be the area under the normal curve between those two points. This area can be calculated using the z-score formula, which is (x-μ)/σ = (41.25-40)/(8/√32). This gives us a z-score of 0.25. The probability can then be calculated using a z-table, which is approximately 0.5987. Therefore, the probability that the sample mean is between 39.75 and 41.25 is approximately 0.5987.

45 divided by 3 is 15. The solution has been obtained by using long division.

What is long division?

When splitting huge numbers, the task is divided into several sequential steps using the long division approach. The dividend is divided by the divisor, just like in conventional division problems, and the result is known as the quotient; occasionally, it also produces a remainder.

Using long division, we get

The total number of unique keys after the distribution will be 48.

When the package containing 12 electrical locks is delivered to 16 job site superintendents, each superintendent will receive 3 locks. This means that the total number of locks will be 16 * 3 = 48

When the locks are distributed, each superintendent will receive 12/16 = 3/4 of a lock. This means that each superintendent will receive 3 locks.

Since each lock comes with a unique key, the total number of unique keys after the distribution will also be 48.

It is important to note that each lock is unique and comes with its own key, so even though the locks are being distributed among 16 superintendents, the number of unique keys will remain the same, which is 48.

The total growth of the plant in 2 weeks is 7/6 inches.

A fraction is defined as a piece of a whole. The complete could be a single thing or a group of objects. The component reflects the percentage of the cake when we really cut a slice of cake from the whole cake. Latin is where the word "fraction" originates.

Given plant grew in the first week = 1/3 inch

the plant grew in the second week = 5/6 inch

total growth in 2 weeks = 1/3 + 5/6

1/3 is equivalent to 2/6 with same diameter,

When comparing sets, a higher mean absolute deviation denotes a greater degree of dispersion of the data points from the mean and vice-versa.

What is mean absolute deviation?

The ratio of the sum of all absolute values of deviation from the central measure to the total number of observations is known as the mean absolute deviation.

We find the mean of the data set first, then use that value to calculate the mean absolute deviation of the data.

The mean absolute deviation reveals how dispersed or concentrated a group of data is around the mean. This is the data's variation.

When comparing sets, a higher mean absolute deviation denotes a greater degree of dispersion of the data points from the mean. Data points are more closely packed around the mean when the mean absolute deviation is lower.

To solve we need to calculate the z-score, but since we are given the sample size then we shall begin as follows:

The z-score is calculated as (320 - 300)/(50/6) = 2.4, which means that the value of 320 is 2.4 standard deviations above the population mean of 300. Using a standard normal table or calculator, we can find the probability that a standard normal random variable is less than 2.4, which is approximately 0.9918.

This means that the probability that the sample mean is greater than 320 is approximately 0.9918. In other words, there is a 99.18% chance that a randomly selected sample of 36 U.S. Marines will have a mean number of pushups greater than 320.

Step-by-step explanation:

The arc length,s, can be calculated using the formula s=r*c, where r is the radius of the circle and c is the central angle in radians. So, for a circle with a radius of 8 inches and a central angle of 2.4 radians, the arc length would be s=8 inches*2.4 radians =19.2 inches

The arc length s cut off by an angle with a measure of 2.4 radians in a circle with a radius of 8 inches is 19.2 inches.

What is the arc length?

Arc length is a measure of the distance along a curved line segment of a circle or a curve. It represents the length of a portion of the circumference of a circle, or the distance between two points on a curved line. In mathematical terms, it is defined as the integral of the magnitude of the velocity vector along the curve. The formula for the arc length of a circle depends on the radius r and the central angle θ (measured in radians) that cuts off the arc. It is given by

s = r * θ

In this case, the radius r is 8 inches, and the central angle θ is 2.4 radians. Plugging in these values, we get:

s = 8 * 2.4 = 19.2 inches

Hence, the arc length s cut off by an angle with a measure of 2.4 radians in a circle with a radius of 8 inches is 19.2 inches.
