Volume of sphere = 1766.25 cm^3

Step-by-step explanation:

The radius of sphere = 7.5 cm

Volume of sphere = ?

The formula used is:

$Volume= \frac{4}{3}\pi r^3$

Putting values:

$Volume= \frac{4}{3}\pi r^3\\Volume=\frac{4}{3}*3.14* (7.5)^3\\Volume= 1766.25\,\,\,cm^3$

So, Volume of sphere = 1766.25 cm^3

NNADVOKAT [17]

You can get the amount that they get, by getting the amount of home runs vs the amount of wins they won, to show how the homeruns affect the wins

you can have x as the wins, and y by the amount of homeruns per win.

Then you can create first a bar graph, and then a line graph, to show how the homeruns affects the victory

hope this helps

Suppose that lower production costs increases the supply of wheat, such that more wheat is supplied at each price level. After t

just olya [345]

When the demand and supply curve intersect, that is, where the quantity demanded and quantity supplied are equal, the market is said to be in equilibrium. Thus, the given quantity is equilibrium quantity.

From the graph, we see that when the production cost of wheat is $4, the equilibrium quantity is 600 units.

When the production cost lowers from $4 to $3, the supply of wheat increases, such that the equilibrium quantity increases from 600 units to 800 units.

Thus, after an increase in supply, the equilibrium quantity increases.

So, Option A is the correct answer.

Answer:

$\mu_{\bar x} = \mu = E(X) =30KWh$

$\sigma_{\bar X}= \frac{\sigma}{\sqrt{n}}=\frac{3}{\sqrt{100}}=0.3$

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

The central limit theorem states that "if we have a population with mean μ and standard deviation σ and take sufficiently large random samples from the population with replacement, then the distribution of the sample means will be approximately normally distributed. This will hold true regardless of whether the source population is normal or skewed, provided the sample size is sufficiently large".

Solution to the problem

For this case we select a sample of n =100

From the central limit theorem we know that the distribution for the sample mean $\bar X$ is given by:

$\bar X \sim N(\mu, \frac{\sigma}{\sqrt{n}})$

So then the sample mean would be:

$\mu_{\bar x} = \mu = E(X) =30KWh$

And the standard deviation would be:

$\sigma_{\bar X}= \frac{\sigma}{\sqrt{n}}=\frac{3}{\sqrt{100}}=0.3$
