I’m sure this is easy but i'm gonna ask anyway

No, it's always okay to ask if you don't understand a question. Anyway, for this problem, we just have to plug in the value for <em>V </em>to solve for <em>P</em> :

$P = 4V^{ \frac{1}{3}} \\ P = 4(125)^{ \frac{1}{3}}$

A number to the power of 1/3 is the same as taking a cube root.

$P = 4(125)^{ \frac{1}{3}} \\ P = 4(5) \\ P=20$

The perimeter of one face of the cube is 20m.

Answer:

a) $P(X$

And we can find this probability using the normal standard table:

$P(z$

b) $P(X>48)=P(\frac{X-\mu}{\sigma}>\frac{48-\mu}{\sigma})=P(Z>\frac{48-46.8}{1.75})=P(Z>0.686)=1-P(z$

And we can find this probability using the normal standard table and the complement ruel:

$P(Z>0.686)=1-P(z$

c) $P(46.8-1.5*1.75$

And we can find this probability with this difference:

$P(-1.009$

And in order to find these probabilities we can use the tables for the normal standard distribution, excel or a calculator.

$P(-1.009$

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".

Assuming the following questions:

Part a: What is the probability that the maximum speed is at most 50 km/h?

Let X the random variable that represent the heights of a population, and for this case we know the distribution for X is given by:

$X \sim N(46.8,1.75)$

Where $\mu=46.8$ and $\sigma=1.75$

We are interested on this probability

$P(X$

And the best way to solve this problem is using the normal standard distribution and the z score given by:

$z=\frac{x-\mu}{\sigma}$

If we apply this formula to our probability we got this:

$P(X$

And we can find this probability using the normal standard table:

$P(z$

Part b: What is the probability that maximum speed is at least 48 km/h?

$P(X>48)=P(\frac{X-\mu}{\sigma}>\frac{48-\mu}{\sigma})=P(Z>\frac{48-46.8}{1.75})=P(Z>0.686)=1-P(z$

And we can find this probability using the normal standard table and the complement ruel:

$P(Z>0.686)=1-P(z$

Part c:What is the probability that maximum speed differs from the mean value by at most 1.5 standard deviations?

$P(46.8-1.5*1.75$

And we can find this probability with this difference:

$P(-1.009$

And in order to find these probabilities we can use the tables for the normal standard distribution, excel or a calculator.

$P(-1.009$
