erik [133]

Answer:

P(X

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

P(Z

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".  

Solution to the problem

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

X \sim N(298,3)  

Where \mu=298 and \sigma=3

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 or excel:

P(Z

Find the perimeter of squared garden if its area is 1369m2​
irina [24]

Answer:

the perimeter is of 148 m

Step-by-step explanation:

the perimeter is the sum of all sides so an square has all sides equal so we have

P = x+x+x+x = 4x

and the area is

A=x^2=1369m^2

so we find x

\sqrt{x^2}=\sqrt{1369}\\\\x=37

and now the perimeter

P=4x\\\\P=4(37)\\\\P=148
