50 paquetes restamos 2500 - 3250 nos da 750, eso lo dividimos en 15 y da 50 1ue es el resultado
Answer:

And we can find this probability with the complement rule and we got:

And using the normal standard table or excel we got:

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 prices of a population, and for this case we know the distribution for X is given by:
Where
and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:

And we can find this probability with the complement rule and we got:

And using the normal standard table or excel we got:

And we can find this probability on this way:
Answer:
(7 , -3)
Step-by-step explanation:
The distance between A and B is 7 squares to the right and 3 squares down
Recall the formula for volume of a cone: V = (1/3)(base)(height).
Here the volume is V = 62.8 cu in. = (1/3)(pi* r^2)(15 in)
62.8 cu in
or, r^2 = -------------------------- = 4 in^2
(1/3)(3.14)(15 in)
Then the radius of the base is sqrt(4 in^2) = 2 in.
Basically use pythagorean theorem to solve :))
